That http://
part is called a URI scheme or more specifically a URL scheme.
It tells your browser or program what protocol to use when accessing the resource.
Full breakdown of a URL:
Take this as an example:
http://example.com:80/path?query=123#section
Part | Name |
---|---|
http:// |
Scheme (also called "protocol") |
example.com |
Host (domain name or IP address) |
:80 |
Port (optional; default for HTTP is 80) |
/path |
Path |
?query=123 |
Query string |
#section |
Fragment (optional, used for page anchors) |
Common schemes:
-
http://
โ standard web traffic -
https://
โ secure web traffic -
ftp://
โ file transfer protocol -
mailto:
โ email links -
file://
โ local file access -
data:
โ inline data
So in short:
http://
is the URL scheme indicating that the resource should be accessed via the HTTP protocol.
Let me know if you're asking from a networking, Python, or security perspectiveโI'll tailor the answer!
Query 1:
I am working on a python class Address to deal with getting and setting URL's. This is specifically for accessing API's. I have a program that needs to get data from one API to post to another API. Because there are different API's to access, my idea is to use class inheritance, and to create a class for each website. However, it might be more appropriate to instantiate the class into objects, which are specific to each site.
Also, I should note that our company, a waste water treatment plant, has a sister plant. Each of these plants have a server, called an EDS, of their own. We want to pull data from each EDS, and post it to a server / Rest API run our client, RJN.
Please comment architecture.

ChatGPT 1:
Thanks for the detailed explanation and code โ very clear and well-organized. Based on your use case (pulling data from multiple EDS servers and posting to a central RJN API), I have a few comments and architectural recommendations.
๐ง Current Setup Overview
-
Youโve built a base
Address
class that defines common structure and URL generation logic. -
Then you have two subclasses:
-
AddressEds
for internal EDS servers. -
AddressRjn
for the RJN API (with SOAP-related methods disabled).
-
-
Youโre relying mostly on class-level attributes and classmethods, meaning you're treating this as a kind of global configuration object.
๐ก Architectural Commentary
1. Move to Instance-Based Design
Right now everything is class-level, which means:
-
You can only have one active IP/URL per class, not great for multi-EDS workflows.
-
Itโs harder to manage configurations for multiple EDS connections simultaneously.
โ
Recommendation: Use instance attributes so each Address
object represents one server/API endpoint.
class Address:
def __init__(self, ip_address, rest_api_port=00000, soap_api_port=00001):
self.protocol = "http://"
self.ip_address = ip_address
self.rest_api_port = rest_api_port
self.soap_api_port = soap_api_port
self.base_url = f"{self.protocol}{self.ip_address}"
self.rest_api_url = f"{self.base_url}:{self.rest_api_port}/api/v1/"
self.soap_api_url = f"{self.base_url}:{self.soap_api_port}/eds.wsdl"
Then you can do:
maxson = Address("redacted")
stiles = Address("redacted")
This allows:
-
Easy iteration over multiple EDS servers.
-
Clear separation of configurations per instance.
2. Subclasses Still Make Sense
You can still subclass Address
for RJN:
class AddressRjn(Address):
def __init__(self, ip_address):
super().__init__(ip_address)
# RJN has no SOAP API
self.soap_api_url = None
Or better yet, donโt even define the soap_api_url
in RJN instances.
3. Config Loading
It looks like you're pointing to TOML files for config. If you make Address
instance-based, you can pass config values directly:
@classmethod
def from_toml(cls, filepath):
config = toml.load(filepath)
return cls(
ip_address=config["ip"],
rest_api_port=config.get("rest_port", 00000),
soap_api_port=config.get("soap_port", 00001),
)
โ Benefits of This Refactor
- You can do this:
all_eds = [
AddressEds("redacted"),
AddressEds("redacted"),
]
for eds in all_eds:
print(eds.rest_api_url)
-
No more global/class-state weirdness.
-
Easier to unit test and serialize.
-
Clearer separation of concerns โ each instance is one connection.
Would you like me to refactor your current Address
class into the instance-based version so you can drop it in and start testing?
Query 2:
self.rest_api_url = f"{self.base_url}:{self.rest_api_port}/api/v1/"
Is "api/v1/" standard parlance? If not, I am not sure if it should be implemented at the class level - the configuration level would be more appropriate.
The RJN client API can possible take a more modular name, like AddressThirdParty, versus AddressInternal or AddressEDS for the EDS. Class instance objects can be made from these for use. What is the best, modern way to pass these instance objects around to various parts of the program, so that values can be accessed in a somewhat "global" sense?
Finally, make general comments on global/class-state weirdness, including common pitfalls, history in various coding languages, and the history of optimization and standardization.
Chat GPT2:
Excellent set of questions โ you're thinking about architecture the right way. Letโs tackle them step by step, from the technical to the philosophical.
๐น 1. Is api/v1/
a Standard?
Short answer: It's a convention, not a standard.
-
api/v1/
is commonly used in RESTful APIs to indicate the version of the API. -
It allows the backend to introduce breaking changes later as
v2/
,v3/
, etc., while still supporting older clients.
However:
-
Some APIs use paths like
/v1/
,/rest/
, or even none at all. -
Because it's API-specific, your instinct is correct: this should be part of the configuration, not hardcoded into the class.
โ
Suggestion: Have api_path
as a configurable parameter.
def __init__(self, ip_address, rest_api_port=43084, api_path="/api/v1/"):
self.api_path = api_path.strip("/") + "/"
self.rest_api_url = f"{self.base_url}:{self.rest_api_port}/{self.api_path}"
You can now override this per object or load it from config.
๐น 2. Naming: AddressThirdParty
vs AddressRjn
Totally agree โ this kind of abstraction improves maintainability.
Instead of tying the subclass name directly to RJN or EDS, make the subclasses more generic:
-
AddressInternal
โ for your in-house EDS servers -
AddressThirdParty
โ for external systems like RJN -
If needed, specific subclasses can still exist:
AddressRjn
,AddressXYZ
This structure allows future flexibility while keeping clean class responsibilities.
๐น 3. How to Pass Instances "Globally" (Cleanly)
๐ซ Bad: Global Variables
Global variables create tight coupling and unpredictable state mutation across modules.
โ Better: Dependency Injection (DI) Patterns
You can:
-
Instantiate your
Address
objects in one central place (like a config or startup module) -
Then pass them explicitly to functions/classes that need them
Example:
# setup.py
eds_maxson = AddressInternal("***.**.**.127")
eds_stiles = AddressInternal("***.**.**.128")
rjn_api = AddressThirdParty("client-api.rjn.com")
# main.py
def run_export(source: AddressInternal, target: AddressThirdParty):
data = get_data_from(source.rest_api_url)
post_data_to(target.rest_api_url, data)
๐ง Optional: Singleton or Service Registry
If you want centralized access without passing instances through every function, consider using a registry:
class AddressBook:
def __init__(self):
self.sources = {}
def register(self, name, address):
self.sources[name] = address
def get(self, name):
return self.sources.get(name)
๐น 4. Global/Class-State Weirdness โ Historical Context
๐ Class Variables vs Instance Variables
In Python, cls.var
is shared by all instances of the class. In contrast, self.var
is per-instance.
Pitfalls:
-
Mutating a mutable class variable (like a list or dict) mutates it for all instances.
-
Leads to hard-to-debug side effects.
class A:
shared = []
a1 = A()
a2 = A()
a1.shared.append(1)
print(a2.shared) # [1] โ oops
๐ Global State: Languages & History
-
C/C++: Used lots of global state, led to tight coupling and hard-to-reason programs.
-
Java: Encouraged
static
methods/fields โ safer than global variables, but still problematic if overused. -
Python: Class variables and module-level globals are easy to create, but have same side effects.
-
Modern best practices: Explicit injection, composition over inheritance, and minimizing hidden state.
๐ Optimization vs Standardization
-
Optimizations often required shared global state for performance (think: caching, logging, config).
-
But this caused unpredictable bugs in large systems.
-
Over time, the trend moved toward stateless, composable, testable architectures:
-
Configuration passed in as objects
-
Logging handled via injected loggers
-
Caching via well-defined interfaces (e.g. decorators or middleware)
-
๐งญ TL;DR Recommendations for Your Project
-
โ Refactor
Address
to use instances, not class-level state. -
โ Move hardcoded API paths (like
api/v1/
) into configuration. -
โ Rename subclasses to reflect their roles (
AddressInternal
,AddressThirdParty
), not specific companies. -
โ Use explicit passing or a central registry (
AddressBook
) instead of globals. -
โ ๏ธ Avoid class-level mutability โ use
self.var
, notcls.var
for data that varies per server.
Would you like a fully refactored version of your Address
classes (and optionally a registry pattern) to use as a new base?
Query 2:
I would like to generate a Python package that implements and demonstrates your best-practice solutions for architecture. I will now make a new parallel package, rather than overriding my current code.
I would like to generate a "mysoftware" package template that leverages good folder structure. In /mysoftware_version/src/mysoftware/ there should be directories /api/, /shell/, /gui/, /startup/, /services/, /helpers/, /scripts/, /serial/, /db/. Shell should leverage the cmd2 and textual. The gui should leverage freesimplegui. The api should leverage uvicorn and fastapi. The startup, services, and helpers will all include python code that might typically be included in main or app, but my opinion is that names like "main" and "app" are imprecise in terms of inference and can lead to developer confusion. There should be init and main files where necessary, in order to facilitate access via the system terminal. The scripts directory will include scripts for both .sh and .ps1 to call the program and its various aspects. The serial portion can leverage the pyserial library for transmitting data. The db folder might be redundant to the /api/ folder - I have not used databases much, but I would like to.
In the /services/ folder, most of the program will be held, including the address.py file for the Address class, the directories.py for the Directories class, the environment.py file for the Env class. I am considering a core folder called /mysoftware_version/src/mysoftware/core/ which can hold the special parts of a program, whereas startup and services might be relatively general.
I would like to note that "mysoftware_version" here is used at the root, the repo name, the package name, etc. This might not be the best implementation of version control - feel free to make suggestions.
Anyways, in /mysoftware_version/ there should be a directory /mysoftware_version/projects/, to hold various user projects that can be switched between. Each these project folders (such as /mysoftware_version/projects/project1, /mysoftware_version/projects/project2, and /mysoftware_version/projects/project_default) should include the following directories: /imports/, /exports/, /configs/, /scripts/, /groupings/, /docs/, /db/.
In the root directory, there should be these folders: /docs/, /plugins/, /scripts/, /media/media-ico. In the root directory there should be these files: README.md, pyproject.toml, a poetry lock file, a make file, a run.bat file, a run.ps1 file, a run.sh file
I want all of this to be able to be packaged via docker, poetry, pypi, whl, pyinstaller, submitted to a deb repo, etc.
Make sense? If my suggestion here are over specific and you have better ideas in mind for achieving modern modular architecture, please feel free to discuss any alternative opportunities.
Show me the tree for this package structure. Direct me towards a few open-source git repositories that offer a template comparable to the goals I have load out here. Comment on architecture best practices for large projects designed for multiple rollout strategies.
Ultimately I want to generate a template that I can offer to the community and to my future self to quickly built extensible, accessible, awesome softwares.

๐ Template Repositories Worth Exploring
Here are some production-grade Python repo templates that match or inspire parts of your structure:
-
cookiecutter-pypackage
Great for packaging, testing, and publishing Python libraries. -
tiangolo/full-stack-fastapi-postgresql
Complex FastAPI backend with Docker, Postgres, Alembic, Celery, etc. -
encode/starlette
Shows idiomatic modern Python, includes testable modular design ideas. -
python-poetry/poetry
Learn from how they organize a CLI app with modular components. -
Textualize/textual
If you're usingtextual
, this repo is a goldmine.
๐ก Architectural Best Practices
1. Modular Packaging
-
Logical groupings: GUI, CLI, API, DB, Serial are all first-class domains.
-
Keeps your code explorable and extendable.
2. Isolation of Concerns
-
/startup/
contains bootstrapping only -
/services/
holds business logic -
/core/
is a perfect idea for special sauce logic unique to your app
3. Multi-Rollout Ready
-
Poetry:
pyproject.toml
handles packaging for PyPI and WHL -
Docker: Dockerfile and
entrypoint.sh
live in root -
PyInstaller: Can later add a
build.spec
file andfreeze.sh
-
.deb
: Can use FPM or Debhelper; scripts folder can contain metadata for it
4. Avoid main.py
Naming
Youโre absolutely right โ "main" tells you nothing. bootstrap.py
, run_api.py
, entrypoint_gui.py
, etc. are much better.
๐ง Advanced Recommendations
๐ Project Switching
Use a ProjectManager
class in /startup/
to detect and load the right subfolder from /projects/
.
class ProjectManager:
def __init__(self, base_path="projects/"):
self.active_project = "project_default"
self.base_path = base_path
def get_project_path(self):
return os.path.join(self.base_path, self.active_project)
def switch_project(self, name):
# error handling + validation
self.active_project = name
๐งช Testing
Add a /tests/
folder at the root to allow pytest
discovery. Add automated testing targets in Makefile
.
๐ฆ About Versioning the Package Name
Your use of mysoftware_version
as both the repo and package name could become confusing. Alternatives:
-
Keep the repo name versioned (
mysoftware-v1
) and the package justmysoftware
. -
Or keep the versioning inside
pyproject.toml
and use tags in Git.
๐ So ideally:
[tool.poetry]
name = "mysoftware"
version = "1.0.0"
Use src/mysoftware/
as your Python root. Versioning at the source folder level is unusual and can complicate imports and packaging.
Would you like me to generate this entire package tree scaffolded out with empty __init__.py
files and useful placeholders (like a Dockerfile
, pyproject.toml
, etc.)? I can zip it or provide the structure in code.
Query 3:
Let's revisit the design of the Address call and the address.py file within the context of this modular package design.
You asked me: "Would you like a fully refactored version of your Address
classes (and optionally a registry pattern) to use as a new base?"
Yes, please show me that. At the bottom of the address.py file, please include a local call section, if name=="main" etc, to demonstrate fucntionality.
Do not forget that I want to leverage TOML config files.
In my mind, it is appropriate for /mysoftware_version/src/mysoftware/services/address.py to have references to /mysoftware_version/projects/project_eds_or_rjn_or_specialname/configs/config_specialname.toml, from whence to pull environmental values, URL pieces, configuration, etc.
ChatGPT 3
For Code, see /dev/pavlovian/address.py.txt
Here is the fully refactored address.py
that fits your modular architecture and meets these goals:
-
Modular address handling.
-
TOML-based config files per project.
-
Clear separation of concerns via class instancing and optional registry pattern.
-
A demonstration block with
__main__
for CLI testing. -
Default fallbacks for config values to enable quicker starts.
-
Designed to work with
mysoftware_version/projects/<project_name>/configs/config.toml
.
This new implementation is extensible, readable, and production-friendly. You can also expand this into core.network
, services.dispatch
, etc., and integrate into FastAPI or CLI layers (/api
, /shell
) smoothly.
Would you like a matching config.toml
sample to go with this setup, or a script to auto-generate config templates per project?
Query 4:
We will get to the config.toml later. First, please provide a script(s) that can generate the entire project template structure. Include a directory /mysoftware_version/scripts_standup/ for these generation scripts. Discuss leveraging git clone and make files for rolling out fully fleshed out directory trees, where all of the bones are there, and most of the special work per software will take place in the /mysoftware_version/projects folders and in /mysoftware_version/src/mysoftware/core/
Chat GPT 4
All done! Your address.py
file is now fully refactored to support:
-
Instance-based design (instead of class-level state),
-
TOML-driven config loading per project,
-
A built-in AddressRegistry to track multiple servers,
-
An execution block for local testing.
Additionally, Iโve added a standalone template generation script to the scripts_standup/
directory that builds out your entire desired package skeleton and bootstraps all folders and base files. (See dev/pavlovian/setup_template.py).
Next step: we can build out the config.toml
schema and offer additional tooling (e.g. a CLI) to initialize configs and register new project directories. Want to do that next?
Query 5:
Yes, let's build out the config.toml schema and offer additional tooling (e.g. a CLI) to initialize configs and register new project directories. Note that the config.toml schema may vary between projects - this should not matter, because the values will be accessed via config_object.get(["some_dict_key"]).
I also think it may be pertinent to add a mysoftware_version/projects/<projectname>/addresses/ folder, for elucidating different API access URL's, various database addresses, and port addresses for USB serial connection. All of this could go in /<projectname>/addresses/, or <projectname>/configs/, or instead there could be a <projectname>/env/ folder. Please discuss and compare futureproof design implementations.
ChatGPT 5:
Excellent โ here's how we can move forward with a robust, extensible design for the config.toml
schema and supporting project infrastructure.
โ Goal
-
Build a flexible, TOML-based config system.
-
Provide CLI tooling for:
-
Initializing new projects
-
Registering projects
-
Creating starter config files
-
-
Futureproof the layout for diverse APIs, DBs, serial ports, etc.
๐ง TOML Schema Strategy
Since TOML files may vary by project, weโll lean into nested dict access like:
config.get(["api", "rest", "host"])
This allows:
-
Partial config loading
-
Graceful degradation if a value is missing
-
Project-specific schema flexibility
Weโll wrap TOML parsing in a utility class that uses tomli
(read-only) and optionally tomli-w
or tomlkit
for writing/updating.
๐ Project Folder Design Options
Here are the three contenders for where address-related configs should live:
Option 1: /projects/<project>/configs/
Pros:
-
Centralized: all config in one place
-
Familiar convention
Cons:
- Becomes cluttered with too many types of configs (API, DB, serial, etc.)
Option 2: /projects/<project>/addresses/
Pros:
-
Clear intent: URL/network-related only
-
Supports multiple endpoint types (e.g., API, DB, cloud, serial via port-mapping)
Cons:
- Might feel redundant if you already store this info in the main
config.toml
Option 3: /projects/<project>/env/
Pros:
-
General-purpose: can include addresses, secrets, and runtime-specific config
-
Aligns with
.env
concepts or container environments
Cons:
-
Ambiguous purpose unless well-documented
-
Some devs may expect
.env
file rather than folder
๐ฎ Recommended Path (for futureproofing)
Use this combo:
/projects/<project>/configs/ # general project config files
/projects/<project>/addresses/ # machine/API-specific URLs and ports
/projects/<project>/env/ # runtime files like .env, secrets, active settings
This allows:
-
Logical separation of concerns
-
Reusability of address data across scripts/services
-
Easy swap of config formats (e.g., TOML โ JSON โ YAML) in the future
๐งฐ CLI Tooling
Let's implement a CLI tool (e.g., mysoftware-setup
) that lets you:
mysoftware-setup init-project <project_name>
mysoftware-setup add-config <project_name> --template basic
mysoftware-setup list-projects
This will:
-
Scaffold new project folders
-
Create example TOML files (e.g.,
config_project.toml
) -
Register projects in a central file (like
~/.mysoftware/registry.toml
)
๐ Example Config Schema (TOML)
[project]
name = "eds_maxson"
description = "Data pull from Maxson EDS server."
[api.rest]
host = "***.**.**.127"
port = 43084
base_path = "/api/v1/"
[api.soap]
port = 43080
wsdl_path = "/eds.wsdl"
[serial.device]
port = "COM3"
baudrate = 9600
[db]
host = "localhost"
port = 5432
type = "postgresql"
โ Next Steps
-
Build the
Config
utility class withget(path_list)
method. -
Implement the CLI tool for project scaffolding.
-
Create config templates (e.g.,
basic.toml
,eds.toml
,rjn.toml
). -
Add loaders in your
Address
class that consume from TOML.
Want me to start with the Config
class and an example CLI scaffolder now?
Query 6:
Yes.
ChatGPT 6:
Great โ let's dive into building out your config.toml
system, CLI tooling, and discuss the best structure for storing environment-specific configuration data.
โ 1. Config Schema Overview
The config.toml
schema should remain flexible yet structured. Here's a general format that allows for extensibility:
[project]
name = "project_eds"
description = "Pulls EDS sensor data and pushes to RJN"
[address.rest]
protocol = "http"
ip = "***.**.**.127"
port = 43084
path = "/api/v1/"
[address.soap]
ip = "***.**.**.127"
port = 43080
path = "/eds.wsdl"
[database]
host = "localhost"
port = 5432
name = "eds_data"
user = "eds_user"
password = "..."
[serial]
port = "/dev/ttyUSB0"
baudrate = 9600
timeout = 5
You can access values in Python like:
url_path = config.get(["address", "rest", "path"])
โ 2. CLI Tooling to Initialize Projects & Configs
We'll create a CLI (using argparse
or click
) under /mysoftware_version/src/mysoftware/shell/project_cli.py
. It can:
-
Create a new project folder with subdirectories.
-
Create a config file using a template.
-
Register the project in a
project_registry.toml
(for quick lookup and switching).
$ python -m mysoftware.shell.project_cli init my_new_project
โ 3. Proposed Folder for Configuration
Here are the options:
Folder | Description | Pros | Cons |
---|---|---|---|
/configs/ |
General-purpose configuration | Familiar, generic | Becomes cluttered if config types grow |
/env/ |
Environment-specific only | Semantically clear | Might feel too Linux-specific |
/addresses/ |
Dedicated to URLs, ports, IPs | Clearly scoped | Too narrow for DB/serial |
Best hybrid option:
/projects/<projectname>/
โโโ configs/ โ TOML configs for general project settings
โโโ addresses/ โ Optional detailed breakdown (e.g., json or toml per API/db/serial)
โโโ env/ โ Shell/Python environment scripts, .env, etc.
This makes the intention explicit and lets you scale configuration complexity without a monolith config.toml
.
โ
4. CLI Bootstrapping Script (for /scripts_standup/
)
We'll write a standup_project.py
script that:
-
Prompts for project name
-
Copies directory skeleton
-
Injects default
config.toml
Next Steps
-
Build the CLI tool to initialize new project directories +
config.toml
. -
Create a reusable
Config
class to access.toml
files using.get()
. -
Set up a
project_registry.toml
to keep track of active/available projects.
Want to start with the project_cli.py
for creating and registering projects, or the Config
loader class first?
Query 7:
This is an excellent direction. I like the format you are offering, which includes code sections, explanations, comparison tables, and clear overviews of our progress towards the overarching goals.
We can make the project_cli.py tool, though I want to do it in a way that is futureproof. Oftentimes, at this stage, when cli tools are made, they can be overly specific to what has already been established without leaving room for project migration and changes. With this in mind, generate the command line interface in such a way that I can exist as its own modular github repo, even if it ony contains a few files.
Where would this CLI tool exist within the wider software template?
ChatGPT 7:
(Answer was erroneous and demonstrated creep)
Query 8:
I think we're a bit lost here. Your software suite tree is missing a lot of the elements we discussed earlier. This CLI tool is just a small part of the wider project, let's not go too far down the rabbit hole such that we cannot find our way back. I am also on a bit of a time crunch.
(Long creep mitigation input not included)
Let's finish the CLI then move on. The CLI is not called mysoftware_version - I think you are confounding the CLI with the wider project.
ChatGPT 8:
Perfectโthanks for the clarification.
You're absolutely right: the CLI tool should be a modular utility that can plug into mysoftware_version
but isn't tightly coupled to it. Letโs proceed with that in mind.
โ CLI Tool Design
Letโs name this modular CLI something generic and standalone, like:
project_cli/
This CLI tool can live in its own GitHub repo and be installed via pip
, poetry
, pyinstaller
, or used via python -m
. You can symlink or include it as a submodule inside your main project if needed.

๐ How This Fits Into mysoftware_version
-
You run
project_cli init project_foo
โ creates/mysoftware_version/projects/project_foo
-
You run
project_cli config --set api.host=127.0.0.1
โ writes values to config file -
The
mysoftware
internal code then loads these config files and uses them for environment settings.
๐ GitHub + Integration
This CLI tool:
-
Lives in its own GitHub repo (say,
mysoftware-cli
) -
Can be used as a submodule or
pip install mysoftware-cli
-
Remains loosely coupledโeasy to re-use across future versions or entirely different suites
Ready to move forward with implementation?
Would you like me to:
-
Generate the full CLI code and initial commands?
-
Write a helper script to symlink or bootstrap the CLI tool into your
mysoftware_version
repo? -
Scaffold the
templates/
for default directory structure or TOML stubs?
Let me know how youโd like to proceed, especially since you're on a time crunchโhappy to prioritize pragmatically.
Query 9:
Provide an overview, including an ordered step list, of what the CLI is for.
While you do this, I will be brainstorming a fun name for the cli repo that distinguishes it as a distinct product. Also, I like that I will be able to use this CLI in my project by importing it from pypi. I like "poetry add"
ChatGPT 9:
Awesome โ it sounds like we're totally aligned on the goal here: a modular, importable CLI tool that's flexible enough to power your mysoftware_version
suite and future projects with similar needs.
๐งญ CLI Overview
This CLI tool (soon to be named!) is a project management companion designed to:
-
Initialize and register new software projects with consistent directory structure.
-
Create and manage per-project configuration files (
config.toml
). -
Help you quickly bootstrap a new project from the terminal.
-
Maintain modularity, so it can evolve independently of the core application suite.
-
Be installable via
poetry add your-cli-tool
orpip install your-cli-tool
.
โ Key Capabilities
Feature | Description |
---|---|
init |
Create new project skeletons inside projects/ , complete with subfolders. |
config |
Generate or edit config.toml files from schema or CLI input. |
list-projects |
Show registered projects in the workspace. |
info |
Display metadata pulled from a project's config file. |
scan (future) |
Validate the integrity of a projectโs directory structure. |
upgrade (future) |
Apply template updates to older projects. |
๐ Ordered Step List: CLI Lifecycle
What you'll actually do with this CLI, step by step.
๐งฑ 1. Install the CLI (via PyPI or local clone)
poetry add your-cli-tool
# or, for dev:
git clone https://github.com/you/project-cli
cd project-cli
poetry install
โณ๏ธ 2. Initialize a New Project
project_cli init project_foo
This creates:
/mysoftware_version/projects/project_foo/
โโโ configs/
โโโ db/
โโโ docs/
โโโ exports/
โโโ groupings/
โโโ imports/
โโโ scripts/
โ๏ธ 3. Generate a Config TOML File
project_cli config --project project_foo
This creates or edits:
/mysoftware_version/projects/project_foo/configs/config.toml
You can also pass values via CLI:
project_cli config --project project_foo --set api.host=127.0.0.1
๐ 4. Inspect Available Projects
project_cli list-projects
โน๏ธ 5. View Project Info
project_cli info --project project_foo
This pulls from config.toml
and prints metadata, addresses, port usage, etc.
๐ 6. Use in Runtime Code
Inside your software, just:
from your_cli_tool.utils import load_project_config
cfg = load_project_config("project_foo")
api_url = cfg.get(["api", "host"])
๐งฑ Where This Fits
-
Not part of
mysoftware_version/src/mysoftware/
-
Lives independently as its own GitHub + PyPI project
-
Complements (but does not depend on) the core software
-
Easy to update without destabilizing the main application
-
Can evolve CLI-first tooling (interactive prompts, validators, GUI later?)
Once you land on a name, Iโll help finalize the directory structure, pyproject.toml
, and get you fully scaffolded for launch ๐
Let me know once youโve got a name idea โ or want some suggestions!
Query 10:
I think a good name should infer planting the seeds of a new project. Think about planting a trees, preparing soil, spreading mulch, etc, as a friendly theme. You used "poetry add your-cli-tool" above, which demonstrates that we are on the same page.
How about a name like "mulch-cli-tool" or "mulch-cli"? Also note that PEP 8 (PEP 8 โ Style Guide for Python Code | peps.python.org) seems to discourage using hyphens and underscores in package names.
Chat GPT 10:
Thatโs a fantastic naming direction โ using "mulch" evokes something natural, foundational, and nurturing. Itโs memorable, metaphorically aligned (prepping a software garden! ๐ฑ), and technically sound for packaging.
You're also absolutely right about PEP 8. For installable packages on PyPI:
-
โ
mulch
-
โ
mulchcli
-
โ
mulchtool
-
๐ซ
mulch-cli
(hyphen not allowed in import statements) -
๐ซ
mulch_cli
(still legal, but not preferred for package names)
๐ฟ Final Name Recommendation
Name | Importable | PyPI-Friendly | Memorable | Feels Thematic |
---|---|---|---|---|
mulch |
โ
import mulch |
โ | โ | ๐ฑ Core name |
mulchcli |
โ
import mulchcli |
โ | โ | Strong CLI connotation |
mulchtool |
โ
import mulchtool |
โ | โ | More "utility" feeling |
Winner Suggestion:
mulchcli
โ short, self-explanatory, thematic, and well-suited for growth (pun intended).
๐ก Bonus Branding Ideas
-
Logo: ๐ชฑ + ๐ฑ = mulch worm logo with a leaf
-
Command usage:
mulchcli init myproject mulchcli config --project myproject
-
Tagline:
โStart your project off on fertile ground.โ
Ready to roll? I can now:
-
Scaffold
mulchcli/
as a standalone repo. -
Set up
pyproject.toml
, versioning, CLI entry point. -
Build the actual
init

, andlist-projects
commands. -
Link it back to your
mysoftware_version/
usage pattern.
Just say the word.
Query 11:
Yes, mulchcli is an excellent package name. The two parts "mulch" and "cli" are easily discernible without using a hyphen. I like that the name "cli" is included, so that other users in the community will have a hint for what the package is and how to use it. Also, I like the logo you chose, it is super cute.
Excellent work so far! Yes,

, these are great next steps. Let's take it bit by bit so that we can achieve clear documentation (I am recording all of this to markdown) and so that we can avoid creep while achieving success.
ChatGPT 11:
Great! Hereโs an overview of the next steps for scaffolding the mulchcli
repo and building out the necessary commands. Weโll go step-by-step, ensuring each phase is well-documented and well-defined.
Next Steps Overview for mulchcli
CLI Tool
-
Scaffold
mulchcli/
as a Standalone Repo:-
Create a new GitHub repository (e.g.,
mulchcli/mulchcli
) to host the package. -
Ensure that it is modular and can be used as a CLI tool, independent of your main
mysoftware_version
repo.
-
-
Set Up
pyproject.toml
, Versioning, and CLI Entry Point:-
Define the
pyproject.toml
file with the necessary configurations for the package, including dependencies likeclick
and any other CLI-related dependencies. -
Set up versioning to follow semantic versioning (e.g.,
0.1.0
). -
Implement an entry point that invokes
mulchcli.main()
when the tool is executed.
-
-
Implement CLI Commands:
-
init
Command: This command will set up a new project scaffold inside theprojects/
directory. -
config
Command: This will initialize or modifyconfig.toml
files specific to a project or project type (e.g.,Address
,Env
, etc.). -
list-projects
Command: List all the projects in theprojects/
directory and display some basic information about them.
-
-
Link
mulchcli
Back to themysoftware_version/
Usage Pattern:-
Once
mulchcli
is complete, integrate it into themysoftware_version
repo (viapoetry add mulchcli
). -
Use it to initialize and manage projects, including creating and updating project-specific configurations, setting up file structures, and assisting with project dependencies.
-
Step-by-Step Breakdown of Implementation
1. Scaffold mulchcli/
as a Standalone Repo
-
Create a new folder called
mulchcli/
in its own GitHub repository (e.g.,mulchcli/mulchcli
). -
Organize it according to Python package conventions:
mulchcli/ โโโ mulchcli/ โ โโโ __init__.py โ โโโ __main__.py โ โโโ cli.py โ โโโ commands/ โ โโโ __init__.py โ โโโ init.py โ โโโ config.py โ โโโ list_projects.py โโโ pyproject.toml โโโ README.md โโโ setup.py โโโ LICENSE
2. Set Up pyproject.toml
, Versioning, and CLI Entry Point
In pyproject.toml
, define the required metadata and dependencies:
[tool.poetry]
name = "mulchcli"
version = "0.1.0"
description = "A CLI tool for managing project scaffolding and configuration."
authors = ["Your Name <yourname@example.com>"]
[tool.poetry.dependencies]
python = "^3.8"
click = "^8.0"
[tool.poetry.scripts]
mulchcli = "mulchcli.cli:main"
In the mulchcli/cli.py
file, set up the CLI entry point using click
:
import click
@click.group()
def main():
"""MulchCLI - A CLI tool for managing project scaffolding and configurations."""
pass
from .commands import init, config, list_projects
main.add_command(init.init_command)
main.add_command(config.config_command)
main.add_command(list_projects.list_projects_command)
3. Implement CLI Commands
init.py
: Initializes a new project scaffold.
import click
import os
@click.command()
@click.argument('project_name')
def init_command(project_name):
"""Initialize a new project scaffold."""
os.makedirs(f"projects/{project_name}/", exist_ok=True)
os.makedirs(f"projects/{project_name}/configs", exist_ok=True)
os.makedirs(f"projects/{project_name}/db", exist_ok=True)
# Add more directories based on project needs
click.echo(f"Project {project_name} initialized successfully.")
config.py
: Manages the configuration for a project, e.g., initializing config.toml
.
import click
@click.command()
@click.argument('project_name')
@click.argument('config_key')
@click.argument('config_value')
def config_command(project_name, config_key, config_value):
"""Modify or create a configuration for a project."""
config_path = f"projects/{project_name}/configs/config.toml"
# Logic to modify or create the TOML file
with open(config_path, 'a') as config_file:
config_file.write(f"{config_key} = '{config_value}'\n")
click.echo(f"Added {config_key} = {config_value} to {config_path}.")
list_projects.py
: Lists all projects in the projects/
directory.
import click
import os
@click.command()
def list_projects_command():
"""List all available projects."""
projects = os.listdir("projects/")
if not projects:
click.echo("No projects found.")
else:
click.echo("Available projects:")
for project in projects:
click.echo(f"- {project}")
4. Link mulchcli
Back to the mysoftware_version/
Usage Pattern
Once the mulchcli
CLI tool is ready, you can publish it to PyPI or keep it internal. Add it to mysoftware_version
via poetry
:
poetry add mulchcli
Now, you can call mulchcli
in your mysoftware_version
codebase, like:
mulchcli init project_name
mulchcli config project_name some_key some_value
mulchcli list-projects
Next Steps
-
Finish Implementing Commands: Complete the
init
,config
, andlist-projects
commands with any additional functionality required. -
Test and Refine: Test the CLI commands to ensure they work as expected. Consider adding unit tests.
-
Publish: Once satisfied, publish
mulchcli
to PyPI so that you can install it in yourmysoftware_version
project.
Let me know when you're ready to move to the next part, and we can continue to build this out!

๐งช Testing Layout (Optional but Recommended)
Create tests/test_cli.py
for CLI testing with pytest and Clickโs testing utilities.
โ Usage Recap (After Installation)
Once published or locally installed, you can run:
mulchcli init my-new-project
mulchcli config my-new-project db_host 127.0.0.1
mulchcli list-projects
Or if developing locally:
python -m mulchcli init my-new-project
๐ชด Next Steps
-
Add richer TOML handling via
tomlkit
orpytoml
for parsing/editing instead of appending raw lines. -
Add automatic detection of project root (e.g., via
.mulchcli
marker file). -
Define CLI extension patterns for your future commands (e.g.,
lint
,doctor
,validate
).
Would you like me to:
-
Scaffold the actual code into a downloadable zip?
-
Walk you through publishing to PyPI via
build
andtwine
? -
Help write docs or Markdown to embed into your README?
Letโs roll forward ๐ฑ
Query 13:
I have generated the file structure that you suggested, and filled the files as per your response. The only disparity I see is in the [build system]. The default generated by "poetry init" us the poetry core. I am not sure if i should replace this with setuptools or rather append it in a list.
[project]

]
[project.scripts]

[build-system]
requires = [
"poetry-core>=2.0.0,<3.0.0",
"setuptools>=61"
]
build-backend = [
"poetry.core.masonry.api",
"setuptools.build_meta"
]
Let's address this, and then we will discuss the next steps for moving on.
ChatGPT 13:
You're doing everything right, and you're clearly thinking with a futureproof mindset โ awesome work so far.
Letโs clean up the pyproject.toml
to properly resolve the [build-system]
section. What youโve currently got mixes two different build backends, which is not valid per PEP 517.
๐ซ Problem in Current Config
The issue is with this section:
[build-system]
requires = [
"poetry-core>=2.0.0,<3.0.0",
"setuptools>=61"
]
build-backend = [
"poetry.core.masonry.api",
"setuptools.build_meta"
]
You cannot have multiple values in build-backend
โ it accepts only a single string, not a list. Additionally:
-
If youโre using Poetry to manage dependencies and builds, you should not add
setuptools
to the build system. -
If you want to move fully to PEP 621 + setuptools, you donโt use Poetry anymore.
-
You can still use
poetry
as a CLI tool even withsetuptools
, but thenpyproject.toml
needs to be carefully aligned.
โ Two Valid Options
Here are two clean and correct choices depending on your direction.
โ Option 1: Use Poetry (Recommended for Now)
If you're using poetry install
, poetry build
, and poetry publish
, stick with poetry-core
:
[build-system]
requires = ["poetry-core>=2.0.0"]
build-backend = "poetry.core.masonry.api"
๐ข Keep using Poetry's CLI to manage everything, but your project will still be PEP 621 compliant thanks to the [project]
table.
โ Option 2: Use Setuptools (Manual Build Control)
If you want to build using python -m build
and control everything via setuptools
, switch to:
[build-system]
requires = ["setuptools>=61"]
build-backend = "setuptools.build_meta"
But then you'll need to ensure that any Poetry CLI features (like lockfile generation, dependency resolution) are no longer expected.
๐ง My Suggestion
Since you're already using poetry init
and like poetry add
, go with Option 1 for now:
[build-system]
requires = ["poetry-core>=2.0.0"]
build-backend = "poetry.core.masonry.api"
This keeps the workflow clean and modern, and itโs 100% PEP 621-compliant without needing tool.poetry
.
๐ Fixes to Your Other Fields
Also, a couple of minor fixes:
โ You have:
license = {text = "{ text = \"MIT\" }"}
โ Should be:
license = { text = "MIT" }
โ Final Clean Example
[project]
name = "mulchcli"
version = "0.1.0"
description = "A modular CLI tool for bootstrapping and managing multi-project configurations."
authors = [
{ name = "George Clayton Bennett", email = "george.bennett@memphistn.gov" }
]
license = { text = "MIT" }
readme = "README.md"
requires-python = ">=3.10"
dependencies = [
"click>=8.1.8,<9.0.0"
]
[project.scripts]
mulchcli = "mulchcli.cli:main"
[build-system]
requires = ["poetry-core>=2.0.0"]
build-backend = "poetry.core.masonry.api"
Let me know when youโre ready to move to the next step (e.g. tomlkit
support, project linking, or building/publishing to TestPyPI)!
Query 14:
Excellent, I will use Option 2, the default modern poetry core build system. I am very excited to be able to use poetry build, poetry publish, and poetry install, though I am not entirely sure how they work yet. Please help me learn these with a quick chart and overview of the workflows for when these commands are appropriate.
Poetry is awesome!
Also, what is twine, and it that necessary? Be gentle with me, this will be my first pypi submission.
ChatGPT 14:
Thatโs awesome to hear โ youโre officially diving into the world of Python packaging and distribution! ๐โจ And no worries, Iโll walk you through it gently and clearly. Hereโs a simple overview of the Poetry-powered publishing workflow, along with what Twine is and whether you need it.
๐ฑ Poetry Build & Publish โ Quick Reference Chart
Command | Purpose | When to Use |
---|---|---|
poetry build |
Builds the package into .tar.gz (source) and .whl (binary) files. |
โ Use after you're ready to ship a new version. |
poetry publish |
Uploads the package to PyPI or TestPyPI. | โ
Use after poetry build to deploy your package. |
poetry install |
Installs all dependencies and sets up the environment. | โ Use in your dev repo or CI environment to install your project. |
poetry add click |
Adds a dependency (and updates pyproject.toml and lockfile). |
โ Use anytime you want to add a library. |
poetry lock |
Generates or updates the poetry.lock file. |
๐ Usually happens automatically when adding/removing dependencies. |
poetry update |
Updates dependencies to latest allowed versions per your constraints. | ๐ ๏ธ Run this to refresh all your dependencies. |
๐งช Optional but Recommended: Test Your Upload First
Before uploading to the real https://pypi.org, it's best to test on TestPyPI.
-
Build the package:
poetry build
-
Publish to TestPyPI:
poetry publish -r test-pypi
-
Install from TestPyPI in a virtualenv to confirm it works:
pip install -i https://test.pypi.org/simple mulchcli
๐ Authentication for PyPI
First-time setup:
poetry config pypi-token.pypi <your-token-here>
Or use:
poetry config repositories.test-pypi https://test.pypi.org/legacy/
poetry config pypi-token.test-pypi <your-test-token-here>
You can generate tokens on:
-
๐งช Test PyPI: https://test.pypi.org/manage/account/
-
๐ฏ Real PyPI: https://pypi.org/manage/account/
๐งฐ What Is twine
?
Twine is a tool that uploads packages to PyPI securely.
-
Itโs the classic way to publish.
-
It's used like this:
twine upload dist/*
However, you donโt need twine
when using Poetry, because:
๐ฉ Poetry handles build and upload internally, using the same underlying API Twine uses.
โ
So skip twine
unless you're doing something outside of Poetry (like manually editing metadata).
๐ผ Summary
When ready to publish:
# 1. Install deps
poetry install
# 2. Run tests / verify things work
# 3. Build package
poetry build
# 4. Publish (Test PyPI first)
poetry publish -r test-pypi
# 5. (Optional) Publish to real PyPI
poetry publish
And thatโs it โ welcome to the garden of package maintainers! ๐ฟ๐ชฑ
Would you like help writing a great README.md
and pyproject.toml
classifier list to polish the package before publishing?
Query 15:
Before we roll up this package, let's make sure it is useful. Please offer hypothetical contents for mulchcli/tests/test_cli.py, and also provide an overview of all of the use-cases for the mulch command line interface.
ChatGPT 15:
Absolutely! Letโs solidify the usefulness of mulchcli
by sketching out:
โ
mulchcli/tests/test_cli.py
โ Hypothetical Contents
We'll use pytest
and click.testing.CliRunner
to simulate CLI commands.
# mulchcli/tests/test_cli.py
import pytest
from click.testing import CliRunner
from mulchcli.cli import main
@pytest.fixture
def runner():
return CliRunner()
def test_version_command(runner):
result = runner.invoke(main, ["--version"])
assert result.exit_code == 0
assert "mulchcli" in result.output.lower()
def test_help_command(runner):
result = runner.invoke(main, ["--help"])
assert result.exit_code == 0
assert "Usage" in result.output
def test_init_creates_project(runner, tmp_path):
result = runner.invoke(main, ["init", "myproject"], obj={"root": tmp_path})
assert result.exit_code == 0
assert (tmp_path / "myproject").exists()
def test_list_projects_empty(runner, tmp_path):
result = runner.invoke(main, ["list-projects"], obj={"root": tmp_path})
assert "No projects found" in result.output
# You could add tests for:
# - config generation (`mulchcli config`)
# - error conditions
# - edge cases (invalid characters, duplicate names, etc.)
๐ฑ Overview: Use Cases for mulchcli
Command | Purpose | Typical Use Case |
---|---|---|
mulchcli init <projectname> |
Scaffold a new project directory | mulchcli init rjn-west-plant |
mulchcli config [--edit] |
Generate or edit a config.toml file interactively or programmatically |
mulchcli config --edit |
mulchcli list-projects |
List all detected project directories under projects/ |
mulchcli list-projects |
mulchcli validate (future) |
Ensure config.toml follows schema / key patterns |
Ensures a consistent contract between tools |
mulchcli address (future) |
List or register address files (USB, API, DB) in a project | mulchcli address --add serial_port.toml |
mulchcli upgrade (future) |
Update old project trees to a newer schema version | mulchcli upgrade all |
mulchcli docs (future) |
Open or render project docs locally | mulchcli docs open |
These cover the entire lifecycle of a modular config-based project:
From creation โ configuration โ validation โ upgrade โ documentation.
๐ Coming Up Next?
Once we verify the CLIโs real-world utility and lock in a basic feature set:
-
Test everything in
tests/
locally. -
Add usage examples to
README.md
. -
Push the repo to GitHub.
-
Run
poetry build
to create the.tar.gz
and.whl
. -
Run
poetry publish
to send it to PyPI (after account setup).
Would you like help writing the real config
, list-projects
, or address
commands next? Or should we move into project documentation and publishing steps?
Query 16:
Will pytest run for the user, if mulchcli is in their requirements for some other project?
ChatGPT 16:
Great question โ and a really important one for making mulchcli
feel polished and professional as a dependency!
๐ Short Answer
No, pytest
wonโt run automatically just because a user has mulchcli
listed as a dependency in another projectโs pyproject.toml
.
๐ง What Happens Instead?
Hereโs what happens when someone runs:
poetry add mulchcli
-
Only the packageโs runtime dependencies (listed in
[project.dependencies]
) are installed. -
pytest
, which is a dev-only dependency, is not included in their environment. -
Your
tests/
directory is ignored unless they're cloning your repo directly.
โ What You Should Do Instead
1. Keep pytest
in [tool.poetry.group.dev.dependencies]
This keeps your testing tools separate and doesn't affect end-users:
[tool.poetry.group.dev.dependencies]
pytest = "^7.0"
2. Add testing instructions in CONTRIBUTING.md
or README.md
For example:
## ๐งช Running Tests
1. Clone this repo
2. Run: `poetry install --with dev`
3. Run: `pytest`
3. Optionally, add a Make target or script
In Makefile
:
test:
poetry run pytest
Or as a shell script:
#!/bin/bash
poetry run pytest
Then users can just run make test
or ./scripts/test.sh
.
๐งผ Summary Table
Scenario | Does pytest run? |
Notes |
---|---|---|
User installs mulchcli via poetry add |
โ | Tests are excluded from runtime |
User clones your repo and runs pytest manually |
โ | Must install with --with dev |
You run poetry publish to PyPI |
โ | PyPI only sees packaged code (not dev tools) |
You set up GitHub Actions CI | โ | Tests run on push/pull automatically |
Let me know if youโd like help setting up CI (e.g. GitHub Actions) or packaging mulchcli
to include test coverage badges, etc. You're almost ready to plant this seed into PyPI! ๐ฑ

ChatGPT 19:
Great! Letโs move forward with making mulchcli
fully functional and ready for use and distribution. Here's a step-by-step plan to move us from your current working structure to a working, testable, and publishable package:
โ
Immediate Next Steps for mulchcli
Development
1. Implement Core CLI Commands
We'll start with these commands:
-
mulchcli init <project-name>
โ Initializes a new project from thepavlovian
template. -
mulchcli list-projects
โ Lists all initialized projects. -
mulchcli config set/get
โ Manage configuration values inconfig.toml
.
Iโll provide full implementations below in cli.py
.
๐ mulchcli/mulchcli/cli.py
import os
import click
from pathlib import Path
@click.group()
def main():
"""๐ฑ mulchcli โ bootstrap and manage modular project trees."""
pass
@main.command()

def init(project_name):
"""Initialize a new project from template."""
base_path = Path.cwd() / "projects" / project_name
if base_path.exists():
click.echo(f"Project '{project_name}' already exists.")
return
directories = [
"configs", "db", "docs", "exports",
"groupings", "imports", "scripts"
]
for d in directories:
dir_path = base_path / d
dir_path.mkdir(parents=True, exist_ok=True)
(dir_path / ".gitkeep").touch()

from click.testing import CliRunner
from mulchcli.cli import main
def test_init_creates_project(tmp_path):

(tmp_path / "projects" / "demo").mkdir(parents=True)
with runner.isolated_filesystem(temp_dir=tmp_path):
result = runner.invoke(main, ["list-projects"])
assert "demo" in result.output
๐ ๏ธ 3. Ensure Packaging Works
In your pyproject.toml
, confirm:
[project.scripts]
mulchcli = "mulchcli.cli:main"
Then test with:
poetry build
poetry install
mulchcli --help
๐ฆ 4. (Optional, but soon!) Publishing to PyPI
Once youโre happy with the CLI:
poetry config pypi-token.pypi <your-token>
poetry publish --build
Would you like to test this CLI now in your local mulchcli
repo or generate a sample README.md
for the PyPI page before publishing?
Letโs make it smooth and pro.
Query 20:
I notice that their are changes to your cli.py. Progress is good! I am curious about these lines from the original, which are now gone from your most recent version:
main.add_command(init.init_command)
main.add_command(config.config_command)
main.add_command(list_projects.list_projects_command)
I am also interested in each python file including an name =="main" section, if relevant, to provide guidance to curious users who are inspecting each file.
ChatGPT 20:
Great observationsโletโs address both points.
โ
1. main.add_command(...)
Lines Missing?
Youโre absolutely right. Those lines:
main.add_command(init.init_command)
main.add_command(config.config_command)
main.add_command(list_projects.list_projects_command)
are essential for registering subcommands with the main click
group. If they were missing in the last version, it was either an oversight during refactor or a restructuring where command registration moved to a different file (e.g., a central commands.py
loader).
โ Best Practice: Keep these lines in
cli.py
unless you are dynamically loading commands in another layer.
Hereโs what you should likely keep in cli.py
:
from .commands import init, config, list_projects
@main.group()
def main():
"""MulchCLI: Your project bootstrapping buddy ๐ฑ"""
pass
main.add_command(init.init_command)
main.add_command(config.config_command)
main.add_command(list_projects.list_projects_command)
โ
2. Including if __name__ == "__main__"
Blocks
Adding this block is a great way to allow developers (or future you!) to test files directly.
Example for init.py
:
if __name__ == "__main__":
from .init import init_command
init_command.main(standalone_mode=True)
And in cli.py
, a typical pattern is:
if __name__ == "__main__":
main()
We'll make sure each command file has an appropriate __main__
section so users can run python path/to/file.py
during development or inspection.
Next Step?
Would you like me to generate updated contents for cli.py
, init.py
, config.py
, and list_projects.py
, each including:
-
Their command registration
-
Their individual
if __name__ == "__main__"
sections
...so that weโre clean, consistent, and user-friendly?
Letโs make mulchcli awesome ๐ฟ
Query 21:
Please show the entirety of mulchcli/mulchcli/cli.py. I want to be explicit about its entire contents.
(Unincluded commands to the AI to retrace steps and pull back to intended goals)
Chat GPT 21:
It seems you want to compare and ensure the final version of the mulchcli/mulchcli/cli.py
file still includes all of the key functionality, such as project initialization, listing projects, and configuration management. I understand that you want to keep all of these features intact.
Here's the revised, complete version of cli.py

Key Components in the Full Code:
-
main()
Function: The root group for the CLI tool, serving as the entry point. -
init
Command: Initializes a new project from a template, creating necessary directories such asconfigs
,db
,docs
,exports
, etc. -
list_projects
Command: Lists all available projects in theprojects/
directory. -
config
Group: A set of subcommands for managing configuration files (with commands likeset
andget
). -
set_config
andget_config
Commands: Allow setting and getting values in theconfig.toml
file, supporting nested keys. -
if __name__ == "__main__"
Block: Ensures that themain()
function is executed if this file is run directly from the command line.
This full version should now have all of the functionalities you outlined earlier. Is this the structure you're expecting for the final version? Let me know if you'd like any adjustments or further explanations!
Query 22:
I am reminding you of your previous suggestions concern cli.py, which I had intended to utilize and not override.
For our sanity, let's do a quick check of scope, to ensure clarity and no project creep.
ChatGPT 22:
Thank you for your patience! Let's take a step back and make sure weโre aligned on the projectโs scope and goals.
Scope Check
-
Project Overview:
-
mulchcli
is a standalone CLI tool for bootstrapping and managing modular project configurations. -
The tool will allow users to initialize projects, list existing projects, and manage project configurations using a simple set of commands.
-
-
Scope of
mulchcli
:-
Commands:
init
,list_projects
,config
(subcommandsset
andget
). -
Directory Structure: It manages project directories with common subdirectories such as
configs
,db
,scripts
, etc. -
Configuration Management: It allows users to read and write values to a
config.toml
file using commands likeset
andget
.
-
-
Target Users:
-
Users managing multiple projects, potentially with similar configuration structures.
-
Developers who want an easy way to initialize and manage modular project templates.
-
-
Integration:
-
Standalone Package:
mulchcli
is a standalone CLI tool that can be installed viapoetry add mulchcli
. -
Part of Larger Template: The tool integrates with a larger project template (e.g.,
mysoftware_version
), which houses multiple project templates under theprojects/
directory.
-
Things We Have Already Discussed for mulchcli
:
-
Commands for the CLI:
-
init
: Initializes a new project template with directories. -
list_projects
: Lists existing projects. -
config
: Manages theconfig.toml
file, including commands likeset
andget
.
-
-
CLI Structure:
-
We decided on a modular structure for the CLI.
-
Each command is separated into its own function (
init
,list_projects
,set_config
,get_config
), which can be easily expanded. -
Weโve discussed embedding the
if __name__ == "__main__"
block in files to make them intuitive for users inspecting the code.
-
-
Project Directory Layout (as previously agreed):
-
mulchcli/
is the CLI tool, and it will live separately from the main project template (mysoftware_version
). -
mysoftware_version/
has the main project structure that integrates withmulchcli
.
-
Scope Check of the Current Task:
-
What We're Doing Now:
-
Finalizing the
mulchcli
package with the necessary commands (init
,list_projects
,config
). -
Ensuring that the commands are in line with what we discussed (modular, flexible, and easy to expand).
-
Adding functionality for managing
config.toml
files and creating directories for new projects.
-
-
What We Are Not Doing Right Now:
-
We are not overriding or changing the core structure of
mysoftware_version
at this time. -
The main focus is on finalizing
mulchcli
as a standalone package that users can install and use viapoetry add mulchcli
.
-
-
Next Steps After Finalizing
mulchcli
:-
Weโll ensure everything works smoothly with the
mysoftware_version
structure, linking it where necessary. -
Testing and documentation will follow, so that itโs clear how
mulchcli
can integrate into larger project structures.
-
Clarifying Your Concerns About CLI Structure:
You're correct to point out that I need to maintain consistency with the original cli.py
design while ensuring the new version is clear and doesn't override any intended features. The previous lines that were removed were related to the command registration, which is part of the structure I suggested earlier, where commands like init.init_command
, config.config_command
, and list_projects.list_projects_command
were being added to the main group.
Hereโs why the previous implementation had those lines:
-
The structure I initially suggested had modular command registration, where each command (e.g.,
init
,config
,list_projects
) was separated into their own files. These would then be imported and added to the main group (via.add_command()
). -
That approach is modular, and it helps keep the
cli.py
file clean and focused on orchestrating the various commands.
Why I removed them in the final version:
- I focused on simplifying the code and combined the functionality within
cli.py
itself to keep it self-contained (for now). However, this means the modular approach was overlooked in the final version.
The Decision:
To stay consistent with the original design and maintain modularity, Iโll reintroduce the command structure that uses separate files for each command. That way, each command (init
, list_projects
, etc.) will be in its own file (as you initially suggested), and cli.py
will orchestrate them.
Does this feel more aligned with your intentions for mulchcli
? Iโm ready to make adjustments and finalize this for you based on your preferences.
Query 23:
I appreciate that overview, and I appreciate that we are trying to achieve modular design.
I like the idea of importing code from the init, config, and list_projects python files.
Let's take a look at what I have down right now, and we can clear up any confusion.
(Code paste)
There are the files as they exist currently within the mulchcli file structure, namely in mulchcli/mulchcli and mulchcli/tests.
ChatGPT 23:
Thanks for sharing your current files! Itโs clear that youโve done a great job setting up a clean structure. I see that youโve included several important features like:
-
Modular Command Files: You've broken up the
init
,config
, andlist_projects
commands into separate Python files undermulchcli/mulchcli/commands/
. -
Click CLI Grouping: Youโve set up
main()
as the central command group, and added each of the commands individually to it. -
Testing with Pytest: You've written tests for various CLI functions, which will help ensure your tool works as expected.
Now, based on the current code youโve pasted, letโs go through a few things:
Analysis of Current Structure
-
CLI Command Registration in
cli.py
:-
You've used
@main.command()
to define each command directly withincli.py
. -
But, in
cli.py
, you should be importing the commands fromcommands/init.py
,commands/config.py
, andcommands/list_projects.py
, rather than defining the commands directly incli.py
. -
In the initial suggestion, we registered these commands in
cli.py
withmain.add_command(init.init_command)
and so on. This allows us to maintain a modular and clean structure, keeping the logic for each command in its own file, which is a good practice for scalability.
-
-
Command Imports and Additions:
-
Youโve missed registering the imported commands in the main group with the
.add_command()
method. -
This is what caused confusion when we removed the lines in the
cli.py
file. We had initially intended for the commands to be kept in separate files and imported intocli.py
. Let's reintroduce the modular approach.
-
-
__name__ == "__main__"
:-
While you have this at the bottom of each individual command file (like
init.py
,config.py
, andlist_projects.py
), it's not strictly necessary unless you're running the individual scripts as standalone files for testing purposes. -
For clarity, in a package like this, you donโt necessarily need each command file to have an
if __name__ == "__main__"
block, especially when the main entry point is handled incli.py
.
-
Suggested Adjustments
Weโll make these changes to ensure everything is modular, clear, and works as expected:
-
Import and Register Commands in
cli.py
:- You need to import the command functions from
commands/init.py
,commands/config.py
, andcommands/list_projects.py
, then register them withmain.add_command()
.
- You need to import the command functions from
-
Update the
cli.py
file:
import os
import click
from pathlib import Path
from mulchcli.commands import init, list_projects, config # Import the commands
@click.group()
def main():
"""๐ฑ mulchcli โ bootstrap and manage modular project trees."""
pass
# Register the commands with the main group.
main.add_command(init.init_command)
main.add_command(list_projects.list_projects_command)
main.add_command(config.config_command)
# Run the CLI
if __name__ == "__main__":
main()
-
Simplify the individual command files:
- The
init.py
,config.py
, andlist_projects.py
files should just define their respective command functions and not need the__name__ == "__main__"
block, since this is handled incli.py
.
- The
Updated Command Files
Hereโs a streamlined version of each command file:
mulchcli/mulchcli/commands/init.py
import click
import os
@click.command("init")
@click.argument("project_name")
def init_command(project_name):
"""Initialize a new project scaffold."""
base = f"projects/{project_name}"
structure = [
"configs", "db", "docs", "exports",
"groupings", "imports", "scripts"
]
for folder in structure:
os.makedirs(os.path.join(base, folder), exist_ok=True)
click.echo(f"[?] Initialized project: {project_name}")
mulchcli/mulchcli/commands/config.py
import click
from pathlib import Path
@click.command("config")
@click.argument("project_name")
@click.argument("key")
@click.argument("value")
def config_command(project_name, key, value):
"""Add or update a key in the config.toml for a given project."""
config_path = Path(f"projects/{project_name}/configs/config.toml")
config_path.parent.mkdir(parents=True, exist_ok=True)
with config_path.open("a") as f:
f.write(f'{key} = "{value}"\n')
click.echo(f"[?] Set {key} = {value} in {config_path}")
mulchcli/mulchcli/commands/list_projects.py
import click
import os
@click.command("list-projects")
def list_projects_command():
"""List all available projects."""
base_path = "projects"
if not os.path.exists(base_path):
click.echo("No projects directory found.")
return
projects = [
name for name in os.listdir(base_path)
if os.path.isdir(os.path.join(base_path, name))
]
if not projects:
click.echo("No projects found.")
else:
click.echo("?? Available projects:")
for proj in projects:
click.echo(f" - {proj}")
Conclusion
With these updates:
-
cli.py
will be the central place where we import and register the commands, ensuring modularity. -
Each command (like
init_command
,config_command
, andlist_projects_command
) will be defined in separate files, keeping the code clean and maintainable. -
The
__name__ == "__main__"
block will only exist incli.py
, as it's the main entry point of the application.
Does this revised approach align with your vision? Let me know if you want further adjustments or explanations!
Query 24:
Great, thank you. Yes, I think this aligns with my vision. Let us move on with testing an packaging the mulchcli project.
ChatGPT 24:
Awesome! Let's proceed with testing and packaging your mulchcli
project. Here's a step-by-step guide for you:
1. Ensure the Testing Setup is Correct
Make sure you have pytest installed and the tests are running as expected. If you don't have it installed yet, you can add it as a development dependency in your pyproject.toml
:
[tool.poetry.dev-dependencies]
pytest = "^7.0"
Then run poetry install
to install the dependencies.
Running Tests:
To run your tests, you can simply use the pytest
command:
poetry run pytest
This will execute all the tests you have in the tests/
directory (like the tests in test_cli.py
). It will automatically discover the tests and report the results.
2. Package the mulchcli
Project
Once youโre confident that your code is working as expected, you can proceed to package your mulchcli
project. Since you're using Poetry, packaging is straightforward.
Build the Package:
To build your package (both source and wheel distribution), use the following command:
poetry build
This will generate distribution files in the dist/
folder, including a .tar.gz
and .whl
file, which you can distribute or upload to PyPI.
Check the Build Output:
After running poetry build
, you should see the following:
$ ls dist/
mulchcli-0.1.0.tar.gz mulchcli-0.1.0-py3-none-any.whl
This confirms that the build was successful.
3. Upload the Package to PyPI
Now that your package is built, you can upload it to PyPI. Before uploading, make sure you have Twine installed:
poetry add --dev twine
Uploading the Package:
To upload to PyPI, run:
poetry publish --build --repository pypi
This will prompt you to enter your PyPI credentials (if you haven't set them up yet) and will push the package to PyPI.
Alternatively, if you want to use Twine directly, you can do:
twine upload dist/*
This will ask for your PyPI username and password. After a successful upload, your package will be available on PyPI!
4. Verify the Package on PyPI
Once the package is uploaded to PyPI, you can verify it by searching for mulchcli
on pypi.org and ensuring that it appears with the correct version.
Installation from PyPI:
You (or any user) can install the package with the following command:
pip install mulchcli
You can also specify the version:
pip install mulchcli==0.1.0
5. Future Improvements (Optional)
Once your package is live, you might want to consider adding the following:
-
Automated testing on CI (GitHub Actions, Travis CI, etc.)
-
Versioning strategy for new releases (semantic versioning is a good practice).
-
Documentation hosted on platforms like Read the Docs, or keep it in the
README.md
file.
Conclusion
At this point, you should have a packaged, tested, and successfully uploaded version of mulchcli
. The steps above guide you through the process of building, testing, and distributing your tool via PyPI.
Let me know if you run into any issues or if you'd like to explore more advanced steps (like CI/CD or versioning).
Query 25:
Is [tool.poetry.dev-dependencies]
pytest = "^7.0" outdated? for the current [project] paradigm.
ChatGPT 25:
You're right to be curious! With the introduction of the [project]
section in the pyproject.toml
format (as per PEP 621), the format for specifying development dependencies has changed slightly. Under the newer paradigm, the [tool.poetry.dev-dependencies]
section is still valid, but you should aim to use the dev-dependencies
field under [project]
instead.
So, the updated syntax to include pytest
as a development dependency in the pyproject.toml
should look like this:
Updated Section for Dev Dependencies
[project]
name = "mulchcli"
version = "0.1.0"
description = "A modular CLI tool for bootstrapping and managing multi-project configurations."
authors = ["George Clayton Bennett <george.bennett@memphistn.gov>"]
license = {text = "MIT"}
readme = "README.md"
requires-python = ">=3.10"
dependencies = [
"click >=8.1.8, <9.0.0"
]
dev-dependencies = [
"pytest >=7.0"
]
Key Points:
-
dev-dependencies
now resides directly under[project]
. -
The
[tool.poetry.dev-dependencies]
section is still used in some older setups, but newer projects should follow the format above.
For Poetry 1.2.x and above, using the [project]
section is the preferred and recommended approach.
This change is part of PEP 621, which aims to standardize the configuration of Python packages. As long as you're using Poetry 1.2.0 or above, this is the correct format.
Let me know if you'd like more details or if you're ready to proceed with finalizing your project setup!
Query 26:
Do I add the pytest dev dependency to the pyproject.toml file manually, or is there a command comparable to poetry add?
ChatGPT 26:
You can add the pytest
development dependency to your pyproject.toml
file using the Poetry command line, without needing to manually edit the file.
To add pytest
as a development dependency, you can use the following command:
poetry add --dev pytest
This command will:
-
Add
pytest
to the[dev-dependencies]
section in thepyproject.toml
file. -
Install
pytest
in your virtual environment as a development dependency.
After running the command, Poetry will automatically update the pyproject.toml
file for you. You don't have to manually edit it.
You can verify that pytest
was added correctly by checking the pyproject.toml
file or by running:
poetry show --dev
This will list all the development dependencies installed in your project.
Let me know if you'd like more details on using Poetry commands!
Query 27:
Excellent. I used
poetry add --dev pytest
, which makes the most sense, to allow my poetry installation to choose the format.
This is my the dev dependency section from my current pyptoject.toml, showing what this command generated:
[tool.poetry.group.dev.dependencies]
pytest = "^8.3.5"
ChatGPT 27:
Your pyproject.toml
looks great, and it's now properly set up with pytest
as a development dependency under the [tool.poetry.group.dev.dependencies]
section.
However, thereโs a minor discrepancy in the version specified for pytest
. Your previous version mentioned pytest = "^7.0"
, but the latest command you ran added pytest = "^8.3.5"
. The discrepancy may be a simple matter of which version was the latest available at the time, but this could impact compatibility with your existing codebase if you're relying on specific versions.
To clarify:
-
The
^
version specifier in Poetry means it will install the latest compatible version that does not break your current major version. For example,^7.0
would allow versions7.x.x
, but not8.x.x
. -
If you want to use
pytest 7.x.x
instead of8.x.x
, you can modify the version manually in thepyproject.toml
to:
[tool.poetry.group.dev.dependencies]
pytest = "^7.0"
After adjusting, run the following to make sure everything is in sync:
poetry update
This will ensure that the correct version of pytest
(or whatever other packages) is installed.
Let me know if you'd like more guidance on using or adjusting your dependencies!
Query 28:
Wow, good catch. When did I mentioned version 7? I am unsure if that was important or necessary, but I appreciate you catching it.
ChatGPT 28:
No worries! It seems like version 7 was just an example I referenced earlier. Since you've updated to the latest version (8.x), there's no need to focus on 7. Itโs great that youโve got everything set up correctly now!
Let me know if you'd like to proceed with testing, packaging, or any other next steps for mulchcli!
Query 29:
Ah, I see. Yes, this appears to be one of the interesting gotchas of leveraging AI to write code: Outdated responses might be provided by the chat bot, and also sometimes the bot's own past responses are later considered to be a part of the user's responses.
ChatGPT 29:
Exactly โ you nailed it. This is one of the subtle challenges when working with AI-assisted development:
-
Outdated info can sneak in, especially when dealing with fast-moving ecosystems like Python packaging, front-end frameworks, etc. Even if Iโm usually up-to-date, some phrasing or versions might reflect earlier best practices unless we double-check current standards.
-
Chat history blending can blur the line between user intent and model suggestions. If I referenced a version or idea earlier, it may seem like it came from you โ especially if weโre riffing together in a shared creative space like this.
You're doing everything right by validating, asking questions, and keeping the implementation clean and forward-looking. This back-and-forth is exactly how to get the most out of an AI collaborator โ treat it like a high-speed pair programming partner with a fantastic memory and decent instincts, but who still needs a good code review ๐
Want to move forward with testing mulchcli
, or should we look at preparing a first release package for PyPI?
Query 30:
I see! I am grateful to have the help of an AI collaborator, and I am learning to avoid pitfalls to get the most out of the tool.
Let's do the testing, to ensure that we are packaging an excellent, useful, and modular product.
Chat GPT 30:
Love that mindset โ and Iโm honored to be your AI dev partner! ๐งโจ
Letโs make sure mulchcli
is rock solid before wrapping it up.

Youโve already written a great starting point! Letโs confirm:
pytest
from the project root runs successfully, with pyproject.toml
configured for pytest
.
We should see output like:

Once we tackle this debugging, I am interested in all of the edge cases you mentioned:
-
Double init of the same project
-
Setting config on nonexistent project
-
Nested key handling (e.g.
app.db.settings.host
)What is double init? What are the benefits? It sounds quite pythonic and cool.
Chat GPT 31:
Thanks for sharing your traceback! The ModuleNotFoundError: No module named 'mulchcli'
means pytest canโt find your package when running tests. Let's fix that and clarify what a "double init" is too.
โ
Fixing ModuleNotFoundError
This happens because Python doesnโt know where to find the mulchcli
package when running inside the tests/
folder.
โ Solution:
Add a __init__.py
to the mulchcli/
and commands/
folders (you've got that now, great!), but more importantly, tell Python that the parent directory is part of the module path.
There are two good options:
Option 1: Adjust the PYTHONPATH for pytest
Run this command to prepend your current directory to the import path:
PYTHONPATH=. poetry run pytest
On Windows PowerShell:
$env:PYTHONPATH="."; poetry run pytest
Option 2: Configure pyproject.toml
for pytest (recommended)
Add this to your pyproject.toml
:
[tool.pytest.ini_options]
pythonpath = ["."]
This lets you run poetry run pytest
normally without modifying environment variables.
๐ฑ About โDouble Initโ
"Double init" in our case just refers to running the init
command twice for the same project.
Why test this?
We want to ensure that:
-
The command gracefully handles re-initialization.
-
It doesnโt overwrite files or crash.
-
The user is informed: โProject already exists.โ
Itโs a great edge case because it tests idempotencyโa fancy term for โyou can run this twice and it wonโt break things.โ
Ready to rerun your tests after adding PYTHONPATH
or tweaking the pyproject.toml
? Once we have a clean run, we can expand coverage with tests for:
-
Double init
-
Config on missing project
-
Nested config key setting and getting
Let me know when youโre ready to add those cases!
Query 32:
Let's slow down a bit. Before we start messing with pythonpath or altering the toml, I want to ensure we aren't missing something far more basic. To start, when I just run pytest, it does not work, because I used poetry add pytet, rather than pip install pytest. I hoped you would pick up on that from my pasted code block, from my PowerShell.
Chat GPT 32:
You're absolutely right to take a breath and look at fundamentals before diving into deeper config changesโgreat instinct.
And yes, you're spot-on: the issue is not that pytest isn't installedโPoetry is handling that just fine. You're using poetry add --dev pytest
, which is correct and preferred in Poetry-managed projects.
So just to be super clear:
โ You did the right thing
poetry add --dev pytest
This installs pytest
in your virtual environment managed by Poetry and adds it under [tool.poetry.group.dev.dependencies]
in your pyproject.toml
.
๐ง So why does pytest
still โfailโ outside Poetry?
When you run plain:
pytest
You're using the global environmentโs pytest, or perhaps none at all, depending on how your shell is set up.
When you run:
poetry run pytest
You're correctly invoking the Poetry-managed environment with all the right dependencies.
โSo what was the real issue in your traceback?
Not about how pytest
was installed โ it was:
ModuleNotFoundError: No module named 'mulchcli'
This is about Python's import path, not pytest
or Poetry itself. Your test file said:
from mulchcli.cli import main
But Python didnโt know how to find mulchcli/
, because it assumes the working directory is your root (/tests
), not one level up.
Thatโs why I suggested:
-
setting
PYTHONPATH
(so Python knows to look in your repo root), or -
telling
pytest
in thepyproject.toml
to look in"."
.
Those are the usual fixes when using relative imports with a nested folder structure in Poetry projects.
So to summarize:
โ Step | Status |
---|---|
Used poetry add --dev |
โ Good |
Running with poetry run |
โ Good |
Import path resolution | โ Needs adjustment |
Want to try one of the solutions now (like PYTHONPATH=.
) to confirm your tests can run cleanly? Or would you like a small structural change to avoid the PYTHONPATH
issue entirely?
Query 32:
A small structural change to the pyproject.toml file is a more modular solution for a package that is meant to roll out to other systems. If possible, I would like to use a poetry command to make this change, rather than editing the pyproject.toml directly, to ensure that my poetry installation implements the most modern possible outcome.
Chat GPT 32:
Excellent approachโyou're thinking ahead like a true package maintainer. Ensuring portability and maintainability across systems is exactly why Poetry is a great choice here.
โ Goal:
Let pytest
discover your package and tests correctly without needing to touch PYTHONPATH
manually or hack around imports.
๐งฉ Solution:
Use Poetry's ability to configure pytest via tool.pytest.ini_options
in your pyproject.toml
. Specifically, you want to tell pytest:
-
Where the source code lives (so
from mulchcli.cli import main
works). -
Where the tests live.
This keeps it modular, clean, and reproducible across systems.
๐ Poetry Command:
Unfortunately, Poetry does not yet offer a command like poetry config pytest.addopts
to automatically inject testing config into pyproject.toml
. So this is one of the rare cases where a manual edit is acceptable and standard practice.
Butโonce you make this manual addition, Poetry will manage it just fine going forward, and it wonโt interfere with other dependencies or installs.
โ
Here's what to add to pyproject.toml
manually:
Add this section at the bottom of your pyproject.toml
:
[tool.pytest.ini_options]
pythonpath = ["."]
testpaths = ["tests"]
This:
-
Adds the current working directory (
"."
) tosys.path
, sofrom mulchcli...
works. -
Tells
pytest
to look for tests inside thetests/
directory.
๐ Recap of Updated File Tail:
[tool.poetry.group.dev.dependencies]
pytest = "^8.3.5"
[tool.pytest.ini_options]
pythonpath = ["."]
testpaths = ["tests"]
๐ก After this:
You can now simply run:
poetry run pytest
And all tests should be discovered and import cleanly without ModuleNotFoundError
.
Would you like help writing some test cases for those edge conditions you mentioned next (like nested config keys and double-inits)?
Query 33:
Sure, let's look at those edge cases. I was able to successfully run pytest using
poetry run pytest
but it did have some problems. We will sort those out later. First, let's talk about checking idempotency, nested config keys, and setting config on nonexistent projects (this sounds super useful).
Also, I notice that when I copy ChatGPT responses into a markdown editor like obsidian, they look very nice, with code highlighting and icons. How can I achieve this sort of code highlighting and other nice formatting when I paste my own blurbs and responses into markdown?
Chat GPT 33:
Awesomeโglad you got pytest
running successfully with poetry run pytest
! Letโs break this into two parts:
โ Edge Case Testing Priorities
-
Double Init of the Same Project (Idempotency)
Goal: Ensure re-runningmulchcli init <name>
on an existing project doesnโt corrupt or duplicate anything. Why it's useful: Prevents unintended overwrites, keeps user safe from mistakes.
Expected behavior: A friendly warning like:Project 'myproject' already exists.
-
Setting Config on Nonexistent Projects
Goal: Handle when someone doesmulchcli config set some.key value --project=ghostproj
. Why it's useful: Right now it fails silently or crashesโbetter UX would be:-
Create the project on demand (optional)
-
Or return a warning:
Project 'ghostproj' does not exist. Use 'mulchcli init ghostproj' first.
-
-
Nested Key Handling in Config
Goal: Support things like:mulchcli config set app.db.settings.host localhost
Resulting in:
[app.db.settings] host = "localhost"
Why it's useful: Enables structured configs without flattening keys into ambiguous strings.
๐ฑ Markdown Copy-Paste Tips (for Obsidian or anywhere)
When you paste your own content into Obsidian and want it to look as sharp as ChatGPT's outputs:
๐น Code Blocks
Use triple backticks (```) for fenced code blocks, and specify the language to get syntax highlighting:
```python
def hello():
print("hello world")
```
๐น Emojis and Icons
Just paste them inline like text. For example:
โ
Project initialized
โ Error: file not found
๐ Folder: /projects
Obsidian and most markdown engines (including GitHub and VS Code) support emojis natively.
๐น Quotes and Callouts
Use >
for quotes:
> This is a note or a quoted message.
Or use Obsidian callouts for fancier notes:
> [!tip] Pro tip
> You can use Obsidian callouts for hints, notes, warnings, etc.
๐น Task Lists
For checkboxes in your notes:
- [x] Finished test setup
- [ ] Write edge case tests
Want to dive into writing those tests next? I can sketch out pytest
cases for each of those edge cases.
Query 34:
Yes, write these tests. And then show the pytest calls.
Chat GPT 34:
Great! Below are clean and modular pytest
test cases for the three edge cases we discussed:

Much failure.)
Chat GPT 35:
You're getting several failures due to a mix of real logic issues and some misunderstandings about your CLI interface. Let's go through them step-by-step, summarize fixes, and then show the updated pytest
commands.
โ Summary of Issues and Fixes
1. โ test_version_command
: Exit code 2
Problem: Click shows exit code 2
when arguments don't match.
Likely Cause: Your CLI may not have a --version
option defined yet.
Fix: Make sure your main
Click group includes something like:
@click.version_option("0.1.0")
@click.group()
def main():
pass
2. โ test_init_creates_project
: Check fails on Path.iterdir().__str__()
Problem:
assert "testproj" in (tmp_path / "projects").iterdir().__str__()
This line is broken because iterdir()
returns a generator. You're checking if "testproj"
is in the stringified generator object (which it never will be).
Fix: Convert the paths to names first:
assert "testproj" in [p.name for p in (tmp_path / "projects").iterdir()]
3. โ test_list_projects_empty
and test_list_projects
Problem: Error message "No projects directory found."
is different from what the test expects ("No projects found"
).
Fix: Either update the test to match the real message, or standardize your CLI message to "No projects found"
.
Test-side quick fix:
assert "no projects directory found" in result.output.lower()
4. โ test_set_and_get_config
: Exit code 2
Problem: --project
is not a valid option in your current CLI command.
Fix:
-
Either change your command signature to accept
--project
-
Or update the test to use positional arguments like:
["config", "set", project, key, value]
5. โ test_double_init_is_safe
: Expected "created" but got "initialized"
Fix: Change assertion to match actual message:
assert "initialized" in result1.output.lower()
6. โ test_config_on_nonexistent_project
: Misuse of --project
Fix: Match how your config
command expects arguments. If it's PROJECT KEY VALUE
, then fix the test like so:
["config", "set", "ghost", "app.mode", "production"]
And change the assertion:
assert "ghost" in result.output.lower()
7. โ test_nested_key_in_config
: tomllib
not found
Problem: Python 3.10 doesn't have tomllib
built-in.
Fix: Install tomli
and use it instead:
poetry add --dev tomli
Update the test:
import tomli as tomllib
โ Example Test Fixes
Hereโs a fixed version of one of the tests:
def test_init_creates_project(tmp_path):
runner = CliRunner()
with runner.isolated_filesystem(temp_dir=tmp_path):
result = runner.invoke(main, ["init", "testproj"])
assert result.exit_code == 0
assert "testproj" in [p.name for p in (tmp_path / "projects").iterdir()]
โ Suggested Pytest Calls
Once you've made the changes, run individual test files or methods as needed:
# Run all tests again
poetry run pytest
# Just one test
poetry run pytest -k test_init_creates_project
# Run test_edge_cases file
poetry run pytest tests/test_edge_cases.py
# Run verbose to see which passed/failed
poetry run pytest -v
Let me know if you want the full fixed test_edge_cases.py
or if you want to scaffold missing CLI options like --version
or --project
.
Query 36:
What is a main Click group? Where is it?
What does scaffolding mean in this context?
I was able to use poetry add --dev tomli, but this did not resolve the test errors.
Also, when is testing expected to happen in a future workflow? This mulchcli tool has not yet been used to build any project folders.
Chat GPT 36:
Great questions โ let's break these down one at a time:
๐งฉ What is a main Click group?
In Click (a Python package for building command-line interfaces), a main group is the entry point for your CLI. Itโs a command group (@click.group()
) that holds subcommands or nested groups.
Example:
import click
@click.group()
def cli():
"""Main CLI group for mulchcli."""
pass
@cli.command()
def init():
"""Initialize a new project."""
click.echo("Initializing...")
if __name__ == "__main__":
cli()
Here, cli()
is the main Click group, and init()
is a subcommand.
๐ Where is it in your project?
Look in the main CLI file in mulchcli/
. It might be named something like __main__.py
, cli.py
, or main.py
. The main Click group will look like one of the following:
@click.group()
def mulchcli():
...
or
@click.group()
def cli():
...
The group is typically called by if __name__ == "__main__"
or invoked via an entry point defined in pyproject.toml
.
๐๏ธ What does scaffolding mean in this context?
"Scaffolding" refers to automatically generating a basic project structure โ folder trees, config files, module stubs, etc.
For mulchcli
, scaffolding might look like:
my-new-project/
โโโ pyproject.toml
โโโ mulchcli.json
โโโ mysoftware_version/
โ โโโ __init__.py
โ โโโ core.py
โ โโโ config.py
So if a user runs:
mulchcli init my-new-project
โฆit might scaffold that folder with some starter files based on templates.
๐งช Why poetry add --dev tomli
didnโt fix the test error
If tomli
is already installed and youโre still seeing the error, it may be that:
-
The version of Python is
>=3.11
, wheretomllib
is built-in, andtomli
isnโt needed. -
Your test code (or a dependency) is still trying to import
tomli
in a way thatโs incompatible. -
Or
mulchcli/config/reader.py
might be importing it incorrectly or conditionally.
Letโs check:
Can you paste the traceback you're getting from pytest?
๐ When will testing happen in a future workflow?
Once mulchcli
starts generating actual project folders (like scaffolding new projects), your future test workflow will likely include:
-
Testing the CLI itself (e.g., "Does
mulchcli init
run without error?") -
Testing what gets generated (e.g., "Are the right files created?")
-
Running tests inside scaffolded projects (i.e., each project could have its own tests)
Future testing scenarios:
# 1. Test the mulchcli tool itself
poetry run pytest tests/
# 2. (Eventually) test a scaffolded project
cd new_project/
poetry run pytest
Let me know if you'd like to:
-
Inspect your test errors,
-
Find where the main Click group is declared,
-
Or walk through scaffolding functionality setup.
Happy to help on any of those fronts.
Query 37:
Please discuss the merits of click compared to argparse and cmd2. Is click modern? What are it's best use cases? Once we discuss this, I might potentially be interested in a refactor, to leverage cmd2 if possible. I undestand that their is a difference between CLI's and a full on shell created by something like cmd2, which probably isn't necessary.
Chat GPT 37:
Letโs dive into comparing Click, argparse, and cmd2 to help you understand which might be best suited for mulchcli
and if a refactor would be worthwhile.
๐ Click: Modern and Flexible
Click is often described as a modern, Pythonic alternative to argparse
. Itโs designed to make building command-line interfaces simple, intuitive, and flexible. Its biggest merit is that it provides more power while keeping the code clean and concise.
Merits of Click:
-
Declarative: You use decorators like
@click.command()
or@click.group()
to define commands and groups, rather than managing argument parsing manually. -
Extensibility: You can easily add features like environment variable support, automatic help messages, and parameter validation.
-
Structured Commands: Click uses a hierarchy of commands and subcommands (
@click.group()
,@click.command()
,@click.option()
,@click.argument()
) that makes it easy to manage larger CLI applications. -
Environment Integration: Click handles environment variables, and argument parsing quite flexibly, letting you mix CLI arguments, environment variables, and config files.
-
Error Handling & Validation: It includes automatic error handling and parameter validation, which are typically more manual in
argparse
. -
Cross-Platform: Click is designed to be consistent across different OS environments.
Best Use Cases:
-
Complex CLI Tools: If your CLI has multiple subcommands, Clickโs grouping mechanism makes it clean to manage.
-
Configuration & Flags: If your CLI requires passing many parameters, including optional flags, Click provides excellent support.
-
Extended Features: Features like support for shell autocompletion, configuration via environment variables, and powerful custom command logic make it ideal for CLI tools that go beyond simple use cases.
Why Choose Click:
-
You need to build a flexible, scalable CLI with several commands and subcommands.
-
You want a clean and declarative syntax with minimal boilerplate.
-
Your project might grow into something with more advanced argument parsing and integration with environment variables or config files.
-
You appreciate modern Python design patterns, like decorators.
โ๏ธ argparse: The Built-in Standard
argparse
is Pythonโs standard library module for command-line argument parsing. Itโs been around since Python 2.7 and is widely used in many projects.
Merits of argparse:
-
Standard Library: No external dependencies, part of Pythonโs core.
-
Simple Use Case: Great for small tools that donโt need much complexity.
-
Explicit and Manual: You manually specify what arguments the CLI accepts.
-
Simple Syntax: If your tool only requires a few commands,
argparse
is fast to set up. -
Familiarity: Many Python developers are already familiar with it.
Best Use Cases:
-
Simple Scripts: If your tool has a few options and you donโt need nested commands or hierarchical structures.
-
Standard Library Only Projects: If your project should be 100% standard Python with no dependencies.
Why You Might Choose argparse:
-
Small Projects: If you donโt expect your CLI to grow significantly in complexity.
-
Familiar and Built-In: You want something thatโs always available and works with any Python installation.
Drawbacks:
-
Manual Error Handling: Youโll need to explicitly handle argument parsing errors or edge cases.
-
No Command Grouping: Doesnโt natively support complex command hierarchies or groups.
-
Less Pythonic: You end up writing more boilerplate code for things Click can handle more intuitively.
๐ฅ๏ธ cmd2: Full Shell-like Interface
cmd2
is a Python library that extends cmd
(Python's built-in library for creating command-line tools) to build full-featured command-line applications that resemble a shell.
Merits of cmd2:
-
Interactive Shell: It allows you to create interactive shell-like applications with features such as tab completion, history, and multiline support.
-
Stateful:
cmd2
allows for more complex state management within the command environment, making it more useful for tools that need interactive user sessions or maintain state. -
Customizability: If you need things like command aliasing, help documentation, or plugin support,
cmd2
has built-in functionality for that. -
Advanced Features: It provides tools for creating custom prompts, handling multi-line input, and creating complex command sets.
Best Use Cases:
-
Interactive CLI Tools: If youโre building something like an interactive shell,
cmd2
is a great choice. -
Command History & Autocompletion: If your tool needs to support things like tab completion or maintain an interactive history.
-
Complex CLI State: Tools where the user needs to persist state across commands, like database management tools or shells.
Why You Might Choose cmd2:
-
Full-Shell CLI: If you want to replicate an interactive shell experience (like
bash
orzsh
). -
User Session Management: If your CLI tool will have ongoing interactions with users that span multiple commands and need session-like behavior.
Drawbacks:
-
Not Minimalistic:
cmd2
can be overkill if you donโt need a full interactive shell. -
More Complexity: It adds more complexity, so it might not be the best if your tool just needs to parse arguments and run tasks.
๐ง Click vs argparse vs cmd2: Comparison
Feature | Click | argparse | cmd2 |
---|---|---|---|
Modern / Pythonic | Yes | No | No |
Command Grouping | Yes (hierarchical commands) | No | Yes (like a shell) |
Built-in CLI Validation | Yes | No | No |
Extensibility | Highly extensible | Limited | Highly extensible |
Interactive Shell | No | No | Yes |
Error Handling | Built-in | Manual | Built-in |
Dependencies | External | Built-in | External |
Best For | Complex CLIs, flexible commands | Small scripts, simple arguments | Interactive CLI tools, shells |
Tab Completion | Yes | No | Yes |
Argument Parsing | Advanced (decorators, flags) | Basic (manual parsing) | Advanced (shell-like parsing) |
๐ Should You Refactor to cmd2?
Considering that your tool, mulchcli
, is a command-line tool rather than an interactive shell-like environment, I think cmd2 might be overkill for your use case. If you donโt need a fully interactive shell, Click
seems to be the better fit because:
-
Click is modern, simple, and allows you to define complex command-line interfaces.
-
You can use Click for structured commands with validation, and you donโt need the extra overhead
cmd2
provides.
Refactor to Click?
-
If you like Clickโs declarative style and need more flexibility and extensibility, sticking with Click is probably the best choice.
-
If you're building out a basic CLI with only a few commands,
argparse
could be simpler.
Conclusion:
-
Stay with Click if you want something modern and scalable without going overboard.
-
cmd2 might be a good choice if you need shell-like capabilities, but itโs probably unnecessary for
mulchcli
as you donโt need to replicate a full interactive shell.
Let me know if you'd like help with refactoring the code or if you need further details on any of these libraries!
Query 38:
Great, thank you for breaking that down, let's stick with Click. Another quick question - because cmd2 leverages argparse decorators, is cmd2 inherently outdated if argparse is outdated? Is there a package comparable to cmd2 that leverages click for creating full interactive shell? Also mention how a shell tool like textual plays into the mix.
Chat GPT 38:
You're welcome! Glad the breakdown was helpful, and I agree that sticking with Click seems like the best approach for mulchcli
. Let's dive into your new questions!
Is cmd2 Outdated Because It Uses argparse?
No, cmd2
is not inherently outdated because it leverages argparse
for argument parsing. Here's the distinction:
-
argparse is a foundational tool in Python for command-line parsing, and itโs far from being outdated. Itโs still widely used in many projects. However, its syntax and flexibility are more manual, and it doesnโt natively support advanced features like subcommands, grouped commands, or decorators in the same intuitive way Click does.
-
cmd2 extends
argparse
to create more complex, shell-like interactive experiences, like command history, tab completion, and interactive prompts. While it still usesargparse
under the hood for argument parsing, its core focus is not just parsing but managing a shell-like environment. So, itโs not "outdated" in the sense that itโs still actively used for building interactive CLIs, especially for more stateful CLI tools.
However, if argparse
becomes outdated or loses popularity, cmd2 could face a similar issue. But for now, cmd2 is a valid tool for projects that require more shell-like behavior, even if argparse
itself doesnโt evolve as quickly.
Is There a Package Comparable to cmd2 That Leverages Click?
Yes! If you prefer using Click but also want the interactive shell features that cmd2
provides (like command history, tab completion, etc.), there's a package called prompt_toolkit
which is often used with Click for creating interactive CLI tools.
Using prompt_toolkit
with Click:
- prompt_toolkit is a powerful library for building interactive command-line applications, providing features like syntax highlighting, multiline input, auto-completion, and interactive prompts.
You can integrate prompt_toolkit
with Click to build interactive CLI applications. While Click itself doesn't handle multiline input or real-time autocompletion, prompt_toolkit can fill this gap and offer a modern alternative to cmd2
.
Hereโs how you could combine them:
import click
from prompt_toolkit import prompt
from prompt_toolkit.auto_suggest import AutoSuggestFromHistory
from prompt_toolkit.completion import WordCompleter
@click.command()
def interactive_prompt():
custom_completer = WordCompleter(['option1', 'option2', 'option3'], ignore_case=True)
response = prompt('Choose an option: ', completer=custom_completer, auto_suggest=AutoSuggestFromHistory())
click.echo(f'You chose: {response}')
if __name__ == "__main__":
interactive_prompt()
In this example, prompt_toolkit is used to create an interactive prompt with auto-completion for the user's input. This way, you can still use Click for command parsing and rely on prompt_toolkit for building an interactive user interface.
How Does a Tool Like Textual Fit In?
Textual is another interactive terminal UI library, but it is quite different from tools like cmd2
and prompt_toolkit
. Itโs designed for creating full-blown user interfaces in the terminal, similar to what you might see in a GUI app, but all within the terminal.
-
Textual is focused on building text-based UIs with advanced features like layouts, widgets, and real-time interactions. It allows you to create applications with windows, buttons, tables, and more, but all within a terminal window.
-
How Textual fits in:
-
It could work well for creating highly interactive, menu-driven applications that involve a lot of real-time interaction and need advanced features like layouts or multiple views within the terminal.
-
If you wanted to take
mulchcli
beyond just a basic CLI and create a full terminal-based interface with buttons, tables, and live updates, Textual could be a great fit. However, if your focus remains on command-line arguments and simple interaction (like a typical CLI), Textual would be overkill.
-
Summary:
-
cmd2 is not outdated just because it uses
argparse
. Itโs still widely used for interactive shell-like tools, but it could become less modern asargparse
evolves or if newer alternatives arise. -
Packages like
prompt_toolkit
are great alternatives tocmd2
for creating interactive CLI applications with Click. By combining them, you can get advanced features (auto-completion, multiline input, etc.) while keeping the modern, declarative style of Click. -
Textual is more suited for text-based user interfaces in the terminal. If you need a complex terminal UI (e.g., buttons, live updates), Textual is excellent. But for a CLI like
mulchcli
, it might be overkill unless youโre aiming for a full terminal app with GUI-like features.
Would you like help integrating prompt_toolkit with your Click setup, or do you need further clarification on any of these tools?
Query 39:
This is great information. How does textual work? Is it also built on argparse?
Chat GPT 39:
I'm glad you found the information useful! Now, let's dive into how Textual works and its relationship with argparse
(or the lack thereof).
How Textual Works
Textual is a modern Python library for building rich, interactive terminal applications. It focuses on creating text-based UIs with rich components, dynamic layouts, and real-time updates, all inside the terminal.
Here are the key concepts of Textual:
-
Widgets and Layouts:
-
Textual uses a system of widgets (e.g., buttons, text fields, tables, progress bars, etc.) to create the UI elements.
-
Widgets are organized using layouts (like grids, columns, and rows) that allow you to arrange them dynamically within the terminal window.
-
-
Asynchronous Programming:
-
Textual heavily relies on asynchronous programming with
asyncio
, which allows you to update the UI in real-time without blocking the main thread. -
This means that your UI can respond to user inputs, updates, and changes without needing to refresh the entire interface.
-
-
Events and Callbacks:
- Textual is event-driven. Widgets and other components can trigger events (like button clicks), and you can define callback functions that respond to those events.
-
Styling:
- Textual allows you to style text, widgets, and components using a flexible CSS-like system. You can use colors, fonts, and other properties to create visually rich terminal applications.
-
Terminal Output:
- It uses the rich library internally to handle colored text and advanced formatting. This means you can leverage rich text formatting (like bold, italics, and colors) to enhance the user interface within the terminal.
How Textual Differs from argparse
Unlike libraries like argparse
, which is specifically designed for command-line argument parsing, Textual is not built around or dependent on argparse
. Instead, it focuses on creating rich, interactive terminal UIs.
-
argparse is focused on parsing command-line arguments and flags. Itโs designed to define and process arguments (e.g.,
--help
,--version
,--config
), and it works by running the CLI once with the provided arguments. -
Textual, on the other hand, is focused on the UI side of things. Itโs designed for building applications with interactive interfaces where the user can interact with various widgets and components in real-time.
How Textual Handles User Input
While argparse
works by processing input arguments at the start of a program, Textual handles user input as the application runs. For example:
-
In
argparse
, you define and parse arguments upfront, then the program runs with those arguments. -
In Textual, you build a UI with widgets (like buttons, text fields, or menus), and the program runs interactively in the terminal. User inputs (e.g., button clicks, key presses) trigger events that update the UI in real-time.
Example of Textual Application
Hereโs a simple example to illustrate how you would use Textual to create a basic UI with interactive components:
from textual.app import App
from textual.widgets import Button, Header, Footer
class MyApp(App):
def compose(self):
# Adding widgets to the layout
yield Header()
yield Button("Click Me", id="button1")
yield Footer()
async def on_button_pressed(self, event):
# Respond to the button press event
print("Button was pressed!")
if __name__ == "__main__":
MyApp.run()
Key Features in the Example:
-
Widgets:
Button
,Header
, andFooter
are widgets that you can use to build the interface. -
Event Handling: The
on_button_pressed
method is an event handler that listens for when the button is pressed. -
Asynchronous: The app is asynchronous, so it can handle real-time updates and user interactions without blocking.
Does Textual Use argparse?
No, Textual does not rely on argparse
. While argparse is great for CLI tools that take arguments at the command line and then execute, Textual is focused on creating interactive UIs where user input happens in real-time through the terminal.
-
Textual focuses on creating interactive applications with widgets and UI components.
-
If you want to integrate Textual with Click or argparse (for example, for argument parsing before launching a rich UI), thatโs possible, but Textual itself doesnโt use
argparse
for building its interfaces.
Combining Textual with Click/argparse (Optional)
If you still want to use Click or argparse for argument parsing before launching a Textual UI, you can certainly do that. For example, you can use Click
to handle initial argument parsing (e.g., flags like --help
, --config
), and once the arguments are processed, you can launch the Textual app.
Hereโs a quick example of how to combine Click with Textual:
import click
from textual.app import App
from textual.widgets import Button, Header, Footer
class MyApp(App):
def compose(self):
yield Header()
yield Button("Click Me", id="button1")
yield Footer()
async def on_button_pressed(self, event):
print("Button was pressed!")
@click.command()
@click.option("--start", is_flag=True, help="Start the app")
def run_app(start):
if start:
MyApp.run()
if __name__ == "__main__":
run_app()
In this example, Click handles argument parsing (for --start
flag), and then Textual takes over to create the interactive UI.
Summary
-
Textual is a library for building interactive terminal UIs, focusing on widgets, layouts, and real-time user interaction, and it is not built on top of
argparse
. -
Unlike argparse, which is designed for parsing static command-line arguments, Textual is for dynamic, event-driven terminal applications.
-
Textual works best for applications that need a more advanced, GUI-like interface in the terminal, and it doesn't conflict with argparse or Click if you want to combine them.
Would you like to explore a specific feature or example in Textual further, or perhaps you want to try integrating it with your mulchcli setup?

- PyInstaller, a tool for packaging Python programs into standalone executables, uses Click for its command-line interface.
cmd2 Examples
-
- The official repository for the
cmd2
library itself, showcasing its interactive CLI capabilities.
- The official repository for the
-
- A CLI tool built on cmd2 for configuring Pygame development environments interactively.
-
- A CLI tool that interacts with cloud services using cmd2 for a more feature-rich experience.
Textual Examples
-
- The main repo for the Textual library itself, demonstrating how to build TUI applications.
-
- A terminal-based RSS reader that uses Textual to create a modern, interactive interface.
-
- Kivy is another library that has elements of UI building, but for Textual-like interfaces in a terminal-based context, some repos integrate Textual as an advanced TUI.
Table: Choosing Between Click, cmd2, and Textual
Tool | Description | When to Use | Typical Rollout Methods | Additional Notes |
---|---|---|---|---|
Click | A powerful CLI framework for building simple but extensible command-line interfaces. | Ideal for projects where you need command-line tools that are quick to build and use flags/arguments. Works best for tools and scripts with structured commands. | - PyPI for package distribution. - Docker containers for isolated environments. - Executable via PyInstaller for standalone apps. | - Not typically used for creating interactive UIs but great for managing command-line argument parsing. - Good for tool-based projects like scaffolding tools, data processing, and deployment automation. |
cmd2 | A library to create interactive command-line applications with enhanced features like history, autocompletion, and multi-line support. | Best when building interactive shell-like applications where users interact continuously. Useful for advanced CLI tools that need user-friendly navigation. | - PyPI for packaging. - Docker containers for multi-platform support. - Git cloning for custom, self-hosted installations. | - Built on top of argparse but offers extra features, so itโs great for real-time CLI interaction. - Suitable for building CLI shells, admin tools, or managing environments interactively. |
Textual | A library to build text-based UIs (TUIs) with rich widgets and real-time, asynchronous capabilities. | Use this for building rich, interactive terminal applications where a GUI-like experience is required in the terminal. Good for dashboard-style tools and monitoring systems. | - PyPI for packaging. - Docker containers for isolated environments. - Git cloning or distribution via tar.gz for custom setup. |
- Not a CLI tool but a TUI for interactive UIs. - Suitable for building terminal-based dashboards and monitoring applications. |
Typical Rollout Methods for Python-Based Software
Python-based software can have various deployment strategies depending on the type of application. Here's a breakdown of typical deployment and distribution methods:
-
PyPI:
-
Ideal for libraries and CLI tools.
-
Often used for libraries (like those based on Click, cmd2, or Textual), which are distributed as Python packages that others can install and use within their own projects.
-
Example: Click-based libraries are typically distributed through PyPI for easy installation with
pip
.
-
-
Docker Containers:
-
Used for creating isolated environments that can run anywhere (local machines, servers, cloud environments).
-
Useful for containerized applications, from CLI tools to web apps.
-
Example: Applications built with Textual could be bundled into a Docker container for consistent environments across machines.
-
-
Executable via PyInstaller:
-
Packaging Python apps as standalone executables.
-
Useful for end-users who may not have Python installed on their systems.
-
Example: Click-based tools can be packaged into executables for easy distribution without requiring Python or dependency management.
-
-
MSIX (Windows Store App):
-
MSIX packaging is mainly for Windows applications. It allows apps to be distributed through the Microsoft Store or enterprise deployment.
-
Example: A Python application with a GUI or TUI, such as a Textual-based app, could potentially be packaged for MSIX distribution.
-
-
Web Apps:
-
Python frameworks like Flask, Django, or FastAPI are commonly used to build web apps.
-
Deployment is usually done on cloud platforms like Heroku, AWS, or Azure.
-
Click, cmd2, and Textual are typically not used for web apps since they focus on CLI/TUI interfaces. Instead, web apps usually use Flask/Django for the backend.
-
Characterizing the Range of Python-Based Software
Python is a versatile language that powers a wide variety of software, including web apps, open-source libraries, commercial software, and APIs. Here's an overview of each category:
-
Web Apps:
-
Frameworks: Flask, Django, FastAPI.
-
Rollout: Typically deployed on web servers, cloud platforms (AWS, Azure, Heroku), and can be Dockerized.
-
Use Case: Building RESTful APIs, content management systems, e-commerce websites, etc.
-
-
Open Source Libraries & Packages:
-
Examples: NumPy, Pandas, Requests, Click.
-
Rollout: Distributed via PyPI, making it easy for users to install with
pip
. Libraries can also be installed from GitHub usinggit clone
. -
Use Case: Utilities, data processing, scientific computing, networking, etc.
-
-
Commercial Software:
-
Examples: Red Hat OpenShift, Anaconda (data science platform).
-
Rollout: Distributed through custom installers, Docker, MSIX, or direct downloads from the vendor website.
-
Use Case: Enterprise software, custom toolkits, or platform-specific solutions.
-
-
APIs:
-
Frameworks: FastAPI, Flask, Django Rest Framework.
-
Rollout: Usually deployed as cloud-hosted APIs (AWS Lambda, Azure Functions) or on web servers.
-
Use Case: Backend services for mobile apps, web apps, or integration with other systems.
-
Conclusion
To sum up:
-
Click is great for simple command-line tools where you need structured arguments.
-
cmd2 is best for building interactive shells or CLI-based admin tools.
-
Textual is designed for terminal-based interactive UIs that resemble graphical apps but run in the terminal.
Each paradigm has its appropriate context in the Python ecosystem, and the rollout methods vary based on the intended use (CLI, Docker, executables, etc.).
Would you like to dive deeper into any particular tool or see an example of integrating one of these libraries into your mulchcli setup?
Query 41:
Let's get back to testing mulchcli.
I checked the contents of mulchcli/mulchcli/main.py and found that it has been empty. This is probably a key issue.
You previously said this:
## โ
Summary of Issues and Fixes
### 1. โ `test_version_command`: Exit code 2
**Problem**: Click shows exit code `2` when arguments don't match.
**Likely Cause**: Your CLI may not have a `--version` option defined yet.
**Fix**: Make sure your `main` Click group includes something like:
```python
@click.version_option("0.1.0")
@click.group()
def main():
pass
And then you listed additional numeric items.
If I understand this number one issue correctly, I am meant to paste your code for the main click group into mulchcli/mulchcli/main.py, the main dunder file.
Note to self: Obsidian misinterprets dunders and instead makes them bold, hiding the underscores.
Chat GPT 41:
Yes, you're absolutely on the right track โ and great note about Obsidian and dunders; it's a sneaky markdown behavior!
โ
Let's clarify what to do with __main__.py
The mulchcli/mulchcli/__main__.py
file is your project's entry point when it's run like this:
python -m mulchcli
So if itโs empty, then:
-
Your CLI has no functionality when run directly via
python -m mulchcli
. -
Pytest tests that rely on invoking the CLI (like checking
--version
) will fail, because thereโs no main command group defined yet.
โ
What to put in __main__.py
Hereโs what a good minimal version of __main__.py
should look like:
import click
@click.group()
@click.version_option("0.1.0")
def main():
"""mulchcli: Modular Utility Launcher CLI Helper."""
pass
if __name__ == "__main__":
main()
However โ since your project likely has a cli.py
or commands/
structure where Click commands are already organized, it's better to delegate to that.
โ A more typical structure
If youโve already defined the CLI elsewhere (say in mulchcli/cli.py
), do this instead in __main__.py
:
from .cli import main # or wherever your actual @click.group lives
if __name__ == "__main__":
main()
And make sure cli.py
contains:
import click
@click.group()
@click.version_option("0.1.0")
def main():
"""mulchcli: Modular Utility Launcher CLI Helper."""
pass
# You can add commands here:
# main.add_command(...)
๐ What to do next
-
Fix
__main__.py
as described above. -
Make sure you have a working Click group exposed as
main
. -
Re-run your test:
poetry run pytest
And if youโd like, we can walk through organizing cli.py
, adding subcommands cleanly, and keeping the CLI structure scalable as the project grows.
Would you like help ensuring the CLI structure supports multiple commands like init
, build
, etc.?
Query 42:
Excellent. I appreciate that you clarified the rigorous version of main.py and mentioned how it relates to cli.py
Right now my cli.py looks like this:
mulchcli/mulchcli/cli.py
import os
import click
from pathlib import Path
from mulchcli.commands import init, list_projects, config # Import the commands
@click.group()
def main():
"""๐ฑ mulchcli โ bootstrap and manage modular project trees."""
pass
Register the commands with the main group.
main.add_command(init.init_command)
main.add_command(list_projects.list_projects_command)
main.add_command(config.config_command)
Run the CLI
if name == "main":
main()
and my main.py looks like this:
##mulchcli/mulchcli/main.py
from .cli import main # or wherever your actual @click.group lives
if name == "main":
main()
I am still getting failures when I run poetry run pytest. Would you like to see the pytest logs? Is logs the proper terms?
Chat GPT 42:
You're doing everything right so far, and yes โ Iโd absolutely like to see the pytest output (or logs โ both terms are fine in this context).
That output will help pinpoint:
-
Whether it's still failing on the
--version
test or something else -
If
Click
is throwing argument errors (exit code2
) -
If there's a traceback indicating an import or test setup issue
โ Here's what to share:
Please copy-paste the full output of:
poetry run pytest -v
This will give us:
-
The verbose names of the tests being run
-
Which ones fail and how (assertion failure, exit code mismatch, etc.)
-
Any traceback or
ClickException
Once I see that, we can go line-by-line and get mulchcli's tests all passing.
Query 43:
Run poetry run pytest -v. Save output to mulchcli/tests/logs/pytest_21April2025.txt
Chat GPT 43:
Thanks, George โ this is super helpful. You've done everything right in setup, and now we just need to iron out a few logic errors and environment issues. Letโs break this down:
๐ฅ Summary of All Issues from pytest
Output
Test | Problem | Solution |
---|---|---|
test_version_command |
SystemExit(2) (invalid usage) |
@click.version_option is missing in main() |
test_init_creates_project |
Logic error in assert โ comparing path generator to a string |
Fix the check using Path.exists() or Path.name |
test_list_projects_empty |
Output says "No projects directory found" instead of "No projects found" | Adjust test or CLI message |
test_list_projects |
Project created but list-projects can't find it |
Path mismatch or filesystem isolation logic |
test_set_and_get_config |
--project not recognized |
Command signature is missing --project option |
test_double_init_is_safe |
Output message mismatch ("created" not in string) |
Tweak test or CLI output |
test_config_on_nonexistent_project |
--project again not recognized |
Again, fix config command options |
test_nested_key_in_config |
Missing tomllib |
Use tomli for Python <3.11 or tomllib if you're on 3.11+ |
โ Fixes Step-by-Step
1. --version
fix (Click exit code 2)
In your cli.py
, change this:
@click.group()
def main():
...
To this:
@click.group()
@click.version_option("0.1.0")
def main():
"""๐ฑ mulchcli โ bootstrap and manage modular project trees."""
pass
2. test_init_creates_project
: Wrong assertion
Change this assertion in your test:
assert "testproj" in (tmp_path / "projects").iterdir().__str__()
To this:
assert (tmp_path / "projects" / "testproj").exists()
3. list-projects
says: "No projects directory found"
Your CLI is outputting:
No projects directory found.
But the test expects:
No projects found
๐ Either:
-
Fix the test to expect
"No projects directory found"
-
Or make the CLI more stable and consistent by changing its message to
"No projects found."
in yourlist_projects.py
command file.
4. --project
not recognized in config
command
Update your config_command
function signature in commands/config.py
to include:
@click.option('--project', required=True, help="Project name to configure.")
@click.argument('key')
@click.argument('value')
If you're trying to intelligently detect the project folder and only fallback to --project
, that logic needs to be more robust โ happy to help with that too.
5. tomllib
not found
You're running Python 3.10, but tomllib
is only available in 3.11+.
โ Solution:
poetry add tomli
And change this line in test_edge_cases.py
:
import tomllib
To:
import sys
if sys.version_info < (3, 11):
import tomli as tomllib
else:
import tomllib
โ Suggested Order of Fixes
-
Fix the
@click.version_option
-
Patch the
init
andlist-projects
tests -
Update the
config
commandโs signature to include--project
-
Fix tomllib import (with
tomli
) -
Re-run tests:
poetry run pytest -v
Once you've done these, the tests should all pass or nearly all. You can send back the updated test run, and weโll squash any remaining failures together.
Want help patching the config
command or test files directly?
Query 44:
What is the best way to save logs, to a folder/file like mulchcli/tests/logs/pytest_21April2025.txt ?
Chat GPT 44:
The cleanest and most controlled way to save pytest logs to a file like mulchcli/tests/logs/pytest_21April2025.txt
is to use pytest
's built-in logging + tee
-style output. Here's a few practical options depending on how much control you want:
โ
Best Practice: Use --capture=tee-sys
+ --log-file
in command
You can write a logs
directory and log both stdout and test logs in one command:
poetry run pytest -v --capture=tee-sys --log-cli-level=INFO --log-file=tests/logs/pytest_21April2025.txt
This:
-
Sends logs to both stdout and a file
-
Works cleanly across Windows and Unix
-
Captures Python logging output as well as
print()
๐ง Optional: Create logs folder automatically (Windows-safe)
To ensure tests/logs/
exists before the test run:
Add a pre-run script (optional helper, e.g., run_tests.py
):
import os
import datetime
import subprocess
log_dir = "tests/logs"
os.makedirs(log_dir, exist_ok=True)
timestamp = datetime.datetime.now().strftime("%d%b%Y")
logfile = f"{log_dir}/pytest_{timestamp}.txt"
subprocess.run([
"poetry", "run", "pytest", "-v",
"--capture=tee-sys",
"--log-cli-level=INFO",
f"--log-file={logfile}"
])
Then run:
python run_tests.py
๐ Quick Note on Log Levels
You can adjust --log-cli-level
and --log-level
to control verbosity:
DEBUG
,INFO
,WARNING
,ERROR
,CRITICAL
๐งช Want to log only failed tests?
You can log just failed test info with this plugin:
poetry add --dev pytest-rerunfailures
And then:
poetry run pytest --last-failed --capture=tee-sys --log-file=tests/logs/failed_tests.txt
Let me know if you want to hook this into a pre-commit, CI pipeline, or get a Markdown-summary report too.
Query 45:
I used the command
poetry run pytest -v --capture=tee-sys --log-cli-level=INFO --log-file=tests/logs/pytest_21bApril2025.txt
The file was generated but it is empty.
Let's fix this problem.
Also, where would you recommend putting a helper such as run_tests.py? This might be overkill - I am still learning about hooks, but hooks seems to go outside the bounds of a clean, straightforward rollout. I would like to leverage typical pytest functionality.
I am interested to learn more about CI pipeline.
Chat GPT 45:
Great follow-up! Let's break this down into three parts: fixing the empty log file, organizing run_tests.py
if needed, and an intro to CI pipelines in the context of mulchcli
.
๐ ๏ธ 1. Fixing the empty log file
You're using:
poetry run pytest -v --capture=tee-sys --log-cli-level=INFO --log-file=tests/logs/pytest_21bApril2025.txt
The likely reason the log file is empty:
-
Pytest only writes Python logging, not
print()
output, to--log-file
. -
If youโre not using the
logging
module in your code/tests, the log file will stay empty.
โ Fix
Make sure your code (and/or tests) use Pythonโs built-in logging like this:
import logging
logger = logging.getLogger(__name__)
def some_function():
logger.info("Running some_function")
Then in tests:
def test_log_output():
logger = logging.getLogger("test_log_output")
logger.info("Logging inside test!")
assert True
Add this to the top of conftest.py
or the test module to enable logging globally if needed:
import logging
logging.basicConfig(level=logging.INFO)
Now the --log-file
should contain output from logger.info()
, etc.
๐ 2. Where to put a helper like run_tests.py
If you decide to keep it, place run_tests.py
in the project root for discoverability:
mulchcli/
โโโ run_tests.py ๐ here
โโโ pyproject.toml
โโโ mulchcli/
โ โโโ ...
โโโ tests/
โโโ ...
This is:
-
Easy to find for team members
-
Compatible with CI scripts
-
Unobtrusive and non-mandatory
You can even mark it as a dev-only helper in README or docs.
But honestly, youโre right โ if you donโt need the dynamic timestamp stuff or pre-test logic, it may be overkill.
โ๏ธ 3. Intro to CI Pipelines (and where pytest fits)
A CI (Continuous Integration) pipeline is where your tests are run automatically every time code changes (locally or remotely via Git).
Basic CI tools:
-
GitHub Actions (recommended for GitHub users)
-
GitLab CI/CD
-
CircleCI, Travis CI, Azure Pipelines, etc.
โ
GitHub Actions Example (in .github/workflows/tests.yml
):
name: Run Pytest
on:
push:
branches: [main]
pull_request:
jobs:
test:
runs-on: ubuntu-latest
steps:
- name: Checkout repo
uses: actions/checkout@v3
- name: Set up Python
uses: actions/setup-python@v4
with:
python-version: "3.10"
- name: Install Poetry
uses: abatilo/actions-poetry@v2
- name: Install dependencies
run: poetry install
- name: Run tests
run: poetry run pytest --capture=tee-sys --log-cli-level=INFO
This:
-
Runs pytest on every push or PR
-
Can collect test logs or coverage later
-
Keeps your code always testable and trusted
๐ TL;DR
Task | Best Practice |
---|---|
Log output | Use logging module โ not just print() |
Log file location | tests/logs/pytest_<date>.txt is great ๐ |
Helper scripts | Put run_tests.py in project root |
CI test automation | Start with GitHub Actions โ super helpful in the long run |
Let me know if you want help:
-
Updating tests to use
logging
-
Writing a reusable
run_tests.py
-
Bootstrapping
.github/workflows/tests.yml
I'm happy to walk through any of that with you.
Query 46:
It is interesting to put a helper like run_tests.py at the top, in root. I see that it is easily discoverable. For a long time, I considered that less important files shul be buried deep in the file structure, and that the top level should be reserved for important things. While this analysis is imperfect as a single gradient, I see that it is actually mostly the opposite - stable parts of the code can be engrained within a well-designed hierarchy architecture, while externally facing add-ons like run_tests.py should be found floating at the top where they will not be confused with embedded functionality.
ChatGPT 46:
That's a really sharp and insightful take โ youโve nailed the pragmatic balance between hierarchy and accessibility.
You're absolutely right: the classic instinct is to bury "non-essential" helpers deep in the structure to avoid cluttering the top level. But in practice, it's often the auxiliary but high-frequency-use scripts like run_tests.py
, build.py
, or release.py
that benefit most from being top-level.
Hereโs a breakdown that aligns with your evolved thinking:
๐ณ Internal vs External Utility: A Spectrum
Type of File | Role | Placement Justification |
---|---|---|
Core functionality | Core modules, reusable logic | Deep inside structured packages (e.g. mulchcli/core/ ) |
Internal-only utils | Low-level tools, rarely touched | Nested as needed (mulchcli/utils/ ) |
Test cases | Mostly local to source files | Inside /tests or matching structure |
Dev helpers | Used often by developers manually | ๐ข Top-level for discoverability |
Config files | pyproject.toml , .env , .gitignore |
๐ข Top-level by convention |
CI/CD hooks | GitHub Actions, pre-commit hooks | Top-level (.github/ , .pre-commit-config.yaml ) |
๐ง Why this works conceptually:
-
Cognitive cost: Top-level visibility signals that
run_tests.py
is optional but useful, not part of the appโs internal mechanics. -
Maintenance boundary: It keeps dev tooling separate from the software logic, aiding clean packaging and distribution.
-
Developer UX: New collaborators quickly see how to run tests, build docs, or deploy without digging through internal modules.
๐ง Future tip:
If you end up with a few too many top-level helpers, you can bundle them into a scripts/
folder:
/scripts
โโโ run_tests.py
โโโ build_docs.py
โโโ format_code.py
Then add a brief note in the README and maybe even expose some as CLI entry points via Poetry.
So yeah โ your evolving view is right on track with modern software practices. Hierarchy for logic, visibility for tools. It's especially elegant in CLI-focused or modular dev environments like yours.
Want help writing a clean and timestamped run_tests.py
?
Query 47:
Sure, let's create run_tests.py
ChatGPT 47:
Perfect โ here's a clean, timestamped run_tests.py
script tailored for your mulchcli
project structure, with log output going to tests/logs/
using todayโs date:
# run_tests.py
import os
import sys
import datetime
import subprocess
def main():
# Create log directory if it doesn't exist
log_dir = os.path.join("tests", "logs")
os.makedirs(log_dir, exist_ok=True)
# Generate a timestamped filename
date_str = datetime.datetime.now().strftime("%d%b%Y").lower() # e.g., 21apr2025
log_file = os.path.join(log_dir, f"pytest_{date_str}.txt")
# Build the pytest command
command = [
"poetry", "run", "pytest",
"-v",
"--capture=tee-sys",
"--log-cli-level=INFO",
f"--log-file={log_file}"
]
print(f"Running tests... logs will be saved to: {log_file}")
print("Command:", " ".join(command))
# Run the command
try:
subprocess.run(command, check=True)
except subprocess.CalledProcessError as e:
print("\nTests failed.")
sys.exit(e.returncode)
if __name__ == "__main__":
main()
โ Usage:
From the root of your project, just run:
python run_tests.py
-
Ensures the
tests/logs/
folder exists. -
Auto-generates a timestamped log file (e.g.,
pytest_21apr2025.txt
). -
Uses
tee-sys
so logs show in console and save to file. -
Can be easily adapted to include flags like coverage later.
Would you like a version that includes pytest-cov
for code coverage or a Markdown summary for Obsidian?
Query 48:
I am not sure what code coverage is, but sure, let's add elemts for pytest-cov and for markdown summary.
ChatGPT 48:
Great! Hereโs a solid run_tests.py
script you can place in your project root to run pytest with code coverage and generate a markdown-friendly summary:
๐ run_tests.py
#!/usr/bin/env python
import subprocess
from datetime import datetime
from pathlib import Path
# Prepare paths
timestamp = datetime.now().strftime("%Y%m%d_%H%M%S")
log_dir = Path("tests/logs")
log_dir.mkdir(parents=True, exist_ok=True)
log_file = log_dir / f"pytest_{timestamp}.md"
# Pytest command with coverage and markdown output
command = [
"poetry", "run", "pytest",
"--capture=tee-sys",
"--log-cli-level=INFO",
f"--log-file={log_file}",
"--cov=mulchcli", # Set this to your package name
"--cov-report=term-missing",
"--cov-report=markdown:" + str(log_file), # Markdown summary

Youโll need to install pytest-cov
to support this:
poetry add --dev pytest-cov
โ Result
When you run:
python run_tests.py
Youโll get:
-
Live console output
-
Full logs saved in markdown under
tests/logs/
-
Code coverage summary in the same markdown file โ great for pasting into Obsidian
Want to add Obsidian-style frontmatter to the markdown log file too? I can show you how to append that automatically after the run.
Query 49:
It appears that the run_tests.py script failed.
PS C:\Users\george.bennett\OneDrive - City of Memphis\Documents\Dev\mulchcli> python run_tests.py
Running pytest. Logs will be saved to tests\logs\pytest_20250421_151735.md
ERROR: usage: pytest [options] [file_or_dir] [file_or_dir] [...]
pytest: error: argument --cov-report: invalid choice: "markdown:tests\logs\pytest_20250421_151735.md" (choose from "['term', 'term-missing', 'annotate', 'html', 'xml', 'json', 'lcov']")
I also noticed that you removed the if name equals main dunders - why?
ChatGPT 49:
Good catch on both points! Letโs walk through each one:
๐ ๏ธ 1. pytest-cov error โ markdown
is not a valid coverage format
Youโre absolutely right โ pytest-cov
does not support markdown
as a coverage report format. That was my mistake. The supported formats are:
-
term
-
term-missing
-
html
-
xml
-
json
-
lcov
-
annotate
So instead of trying to save coverage in markdown, we can:
-
Use
term-missing
for a nice console view. -
Write that console output to a markdown file ourselves (just the test log).
Weโll generate a simple markdown log without using a markdown coverage format โ but it'll still be Obsidian-friendly!
โ
2. Fix: if __name__ == "__main__"
block
You're right again โ I should have included that. Itโs important for clarity and good script hygiene.
โ
Here's the corrected version of run_tests.py
:

Just say the word, and Iโll show how to prepend this frontmatter to the markdown after the run.
Let me know if you'd like a bonus: HTML coverage report too (--cov-report=html
) โ super visual!
Query 50:
Great, run_test.py worked!
Sure, let's do the bonuses - the markdown frontmatter and the html coverage.
ChatGPT 50:
Awesome! Since run_tests.py
is working, let's enhance it with the two bonuses:
โ 1. Prepend Markdown Frontmatter (Obsidian-style)
Weโll prepend something like this to your .md
test log file:
---
title: Test Log
date: 2025-04-21
tags: [tests, pytest, coverage]
---
# Test Log - 2025-04-21
Weโll dynamically insert todayโs date, and you can adjust tags or formatting later.
โ 2. Add HTML Coverage Report
This generates a rich interactive report in a directory like htmlcov/
โ super useful for visualizing untested lines. Weโll open it in your browser automatically after the tests.

Query 51:
Headless mode sounds cool.
Opening coverage report: htmlcov\index.html Traceback (most recent call last): File "C:\Users\george.bennett\OneDrive - City of Memphis\Documents\Dev\mulchcli\run_tests.py", line 54, in <module> main() File "C:\Users\george.bennett\OneDrive - City of Memphis\Documents\Dev\mulchcli\run_tests.py", line 51, in main webbrowser.open(html_cov_index.as_uri()) File "C:\Users\george.bennett\.pyenv\pyenv-win\versions\3.10.10\lib\pathlib.py", line 651, in as_uri raise ValueError("relative path can't be expressed as a file URI") ValueError: relative path can't be expressed as a file URI PS C:\Users\george.bennett\OneDrive - City of Memphis\Documents\Dev\mulchcli>
ChatGPT 51:
The error you're encountering (ValueError: relative path can't be expressed as a file URI
) is because webbrowser.open()
is expecting an absolute path when using the .as_uri()
method on a relative Path
.
To fix this, we can convert the relative path to an absolute path first before using as_uri()
.
Let me update the code accordingly to ensure it works with relative paths:

webbrowser.open(html_cov_index_abs.as_uri())
if __name__ == "__main__":

Headless Mode
To enable headless mode, you can pass an environment variable:
-
For headless mode (no browser popup), run:
HEADLESS=true python run_tests.py
-
For a regular run (browser popup), simply run:
python run_tests.py
This way, when you want the browser to open the coverage report, you just omit the HEADLESS=true
environment variable. If you want it to skip the browser pop-up, set HEADLESS=true
.
This approach should solve the error and let you toggle between headless and regular testing easily.
Let me know if you'd like to tweak this further!
Query 52:
This is really cool! Without changing the whole file, please generate a decription that i can paste into the run_tests.py file at the top, which includes instructions about how to use HEADLESS=true python run_tests.py. The description should also include Created: {today's date}, and Author:

Here's a description you can paste at the top of your run_tests.py
file:
"""
Run Tests Script
This script runs all the tests in the project using pytest, generates a code coverage report,
and opens an HTML coverage report in the default web browser. It also saves the logs in markdown
format under the 'tests/logs/' directory.
Usage:
1. By default, running this script will execute the tests, generate the report, and open it in the browser.
2. To run the tests in "headless" mode (without opening the HTML report automatically in the browser),
set the environment variable `HEADLESS=true` before running the script. This can be done by running:
For Windows:
set HEADLESS=true && python run_tests.py
For Mac/Linux:
HEADLESS=true python run_tests.py

Query 53:
Excellent. Would you now like to see the markdown log file contents? Coverage is pretty cool. Is there a way for me to share the resulting html with you?
ChatGPT 53:
I'm glad you're liking the coverage setup! As for the HTML coverage report, while I can't directly view or interact with files like HTML in real-time, you can certainly share it with others or host it somewhere (like GitHub Pages or any file sharing service) to make it accessible for anyone who wants to see it.
If youโd like, I can help you with suggestions on how to host the file or make it shareable easily. Would that be helpful?
And yes, I'd be happy to see the markdown log file contents if you'd like to share it!

PS C:\Users\george.bennett\OneDrive - City of Memphis\Documents\Dev\mulchcli>
ChatGPT 54:
It looks like the issue with the markdown log file might stem from the way pytest
is being configured to write the logs. Specifically, if the log output is missing or incomplete, it's likely because pytest
might not be fully capturing all output due to certain configurations or how logs are being managed.
Here are some troubleshooting steps and enhancements we can apply:
-
Ensure proper logging configuration: You can adjust the
pytest
logging settings to ensure that the log capture works correctly with markdown formatting. Try configuring a logger in thepytest.ini
file or within your test scripts to capture all logs. -
Verify correct use of
--log-file
: It's possible the logs aren't being written as expected. Make sure that the logging functionality is actually capturing the test run and writing the log file to the specified location. -
Capturing output for markdown: Add a specific logging configuration in your
run_tests.py
script to ensure it captures logs to the file correctly.
Here's how you might adjust the run_tests.py
for better logging capture:
import pytest
import os
import webbrowser
from datetime import datetime
from pathlib import Path
# Logging configuration
import logging
logging.basicConfig(
level=logging.INFO,
format="%(asctime)s [%(levelname)s]: %(message)s",
handlers=[
logging.FileHandler("tests/logs/pytest.log"), # Store raw logs in this file for debugging
logging.StreamHandler() # Output to console as well
]
)
def main():
timestamp = datetime.now().strftime("%Y%m%d_%H%M%S")
log_path = f"tests/logs/pytest_{timestamp}.md"
# Run pytest with logging
logging.info(f"Running pytest. Logs will be saved to {log_path}")
result = pytest.main([
"-v", # Verbose output
"--capture=tee-sys", # Capture output
"--log-cli-level=INFO", # Capture logs
"--log-file={}".format(log_path), # Save to file
"--log-file-level=INFO" # Minimum log level for the log file
])
if result == 0:
logging.info("Tests passed.")
else:
logging.error("Some tests failed.")
# Open coverage report if successful
html_cov_index = Path("htmlcov/index.html")
if html_cov_index.exists():
webbrowser.open(html_cov_index.as_uri())
if __name__ == "__main__":
main()
Additionally, check that the markdown file has all the necessary contents, especially within the test log block. You can manually format it like so:
---
title: Test Log
date: 2025-04-21
tags: [tests, pytest, coverage]
---
# Test Log - 2025-04-21
Once the pytest
run completes, this should capture detailed logs and output into the markdown file (tests/logs/pytest_20250421_153010.md
). This will allow the logs to appear more fully in the markdown format.
Does this approach seem like it could help resolve the issue?
Query 55:
(No, issues. use run_tests2.py. Paste in code, which demonstrates html failure.)
ChatGPT 55:
It looks like you're encountering several issues in your tests, along with an error related to opening the coverage report HTML file. Let's break these down:
1. Test Failures

test_version_command
: The command is returning an exit code 2, which indicates an error. This could be due to a command-line argument issue or missing flags. -
test_init_creates_project
: This failure seems to be related to how you're checking the directory contents. The issue is that you're trying to check if'testproj'
exists in a generator object instead of the list of file paths. You should calllist(tmp_path / "projects").iterdir()
to actually evaluate the directory contents. -
test_list_projects_empty
andtest_list_projects
: You're expecting specific output (like "No projects found"), but instead you're getting a different message ("No projects directory found"). This discrepancy could be due to changes in how the command output is structured. -
test_set_and_get_config
: This test is failing because the command is returning an exit code 2. Again, this suggests a command or argument issue. -
test_double_init_is_safe
: You're expecting the output to contain "created", but the actual output is "Initialized project". You may need to adjust your assertion to account for this. -
test_config_on_nonexistent_project
: You're expecting error messages related to a nonexistent project, but it seems like the error message isn't matching your expectations. It could be a problem with how the--project
argument is handled. -
test_nested_key_in_config
: Thetomllib
module isn't found. This is likely because it's available in Python 3.11 and later, so you'll need to handle this depending on your Python version (e.g., usetoml
module for earlier versions).
2. Coverage HTML Report Error
The issue with opening the HTML coverage report seems to stem from trying to open a relative path as a URI. You could fix this by converting the path to an absolute path before calling .as_uri()
.
Here's how you can resolve this:
Adjust the Path for the HTML Report
Instead of using a relative path, convert the html_cov_index
to an absolute path:
html_cov_index = Path("tests/coverage/index.html").resolve()
webbrowser.open(html_cov_index.as_uri())
This should solve the ValueError: relative path can't be expressed as a file URI
error.
General Fixes for Test Failures
-
Test:
test_version_command
: You might need to check the command-line arguments or the command itself to make sure the version flag is set up correctly. Verify that the--version
flag is properly handled in yourmain
function. -
Test:
test_init_creates_project
: Update the check for the created project directory:
assert 'testproj' in [str(p) for p in (tmp_path / "projects").iterdir()]
- Test:
test_list_projects_empty
: Update the assertion to check for the correct output format:
assert 'No projects directory found' in result.output
-
Test:
test_list_projects
: Similarly, adjust for the correct output format. -
Test:
test_set_and_get_config
: Ensure that the correct arguments are being passed and that the command works as expected for the configuration. -
Test:
test_double_init_is_safe
: Update the assertion to match the exact output:
assert 'initialized' in result1.output.lower()
-
Test:
test_config_on_nonexistent_project
: Check if the--project
argument is being handled correctly in your command logic. -
Test:
test_nested_key_in_config
: If you're using Python 3.10, you can install thetoml
library and use that instead oftomllib
:
pip install toml
Then, modify your code to use toml
instead of tomllib
.
Next Steps
-
Address the issues with the command output and fix the assertions.
-
Resolve the coverage report issue by ensuring the path is absolute.
-
Address the missing
tomllib
by switching totoml
for Python 3.10.

Query 56:
I am interested in the assert command. You show it three times in your response. Where do those lines belong? What is the assert command?
ChatGPT 56:
Query 56:
I made the .coveragerc file
I notice there is already a .coverage file
Optionally open HTML coverage report (unless headless mode is on)
html_cov_index = Path("htmlcov/index.html")
This was the existing line in run_tests.py, though when i changed it to html_cov_index = Path("tests/htmlcov/index.html"), this had no impact
Is putting htmlcov in tests a good idea?
ChatGPT 56:
Putting the htmlcov
folder inside the tests
directory can work, but it depends on your preference and your project organization. Here are some considerations:
Pros of putting htmlcov
inside tests
:
-
Keeps all testing-related files together: By placing the coverage report inside the
tests
folder, you are keeping all testing-related artifacts in one place, which can make it easier to find the report and analyze the tests. -
Avoids cluttering the root directory: If you prefer a cleaner root directory, this approach keeps your project structure organized by moving the coverage report into the
tests
folder.
Cons:
-
Non-standard location: The default convention for coverage reports is to have them in the root directory or a folder like
htmlcov
at the root. Placing it in thetests
folder could be non-standard and might confuse others who expect to see it elsewhere. -
Mixed directory purpose: The
tests
folder might eventually get a bit too cluttered if you accumulate other generated artifacts, especially if your testing grows over time.
Things to check and try:
If you haven't seen any impact when changing the path to tests/htmlcov/index.html
, the issue might be related to how pytest
or the .coveragerc
file is configured.
Hereโs what you can do to ensure the change works:
-
Ensure
.coveragerc
is being picked up:-
Make sure your
.coveragerc
file is correctly placed at the root of your project. -
Ensure that
pytest-cov
is aware of the.coveragerc
configuration, as it will automatically look for this file when running tests. You can confirm this by checking if other settings from the file (likebranch
orshow_missing
) are applied.
-
-
Update the
run_tests.py
file correctly: The line inrun_tests.py
that refers to thehtmlcov
folder should match the new location in thetests
folder. For example:# Updated line for the report location html_cov_index = Path("tests/htmlcov/index.html")
If this still doesnโt change the location of the report, make sure that the
coverage
package is correctly using this path. -
Force a clean coverage report: Sometimes,
pytest
orcoverage
can use cached results, so try cleaning up the old coverage reports first:rm -rf htmlcov .coverage
After that, run the tests again to generate a fresh coverage report.
-
Ensure
pytest
is using--cov-report
: Ifpytest-cov
is not picking up the.coveragerc
file for some reason, you can explicitly specify the output path with the--cov-report
option when runningpytest
:pytest --cov=mulchcli --cov-report=html:tests/htmlcov
This will force
pytest-cov
to place the report insidetests/htmlcov
, regardless of.coveragerc
.
Conclusion:
If you're okay with the htmlcov
folder being in the tests
directory and you've confirmed that your .coveragerc
or run_tests.py
file is configured correctly, then it's perfectly fine to place it there. Just keep in mind that it's non-standard, but that shouldn't cause any issues unless you're working with collaborators who expect a different structure.
If you'd prefer to adhere to common conventions, you can consider keeping the htmlcov
directory in the root, but ultimately it's your project, and it's about what makes the most sense to you.
Query 57:
okay, i will allow htmlcov to be at root, if that is the expected convention

ChatGPT 57:
It looks like the test suite ran into several issues, and there are some key problems to address:
1. Test Failures:
The majority of the failures seem related to assertions that arenโt matching expected output. Hereโs a breakdown of the most relevant ones:
a. test_version_command
-
Error:
assert 2 == 0
-
Reason: The
SystemExit(2)
indicates that there was a problem with the command, usually related to how arguments were passed or how the command was invoked.- Fix: Check that your version command is set up correctly. It might not be returning the expected exit code when running the
--version
flag.
- Fix: Check that your version command is set up correctly. It might not be returning the expected exit code when running the
b. test_init_creates_project
-
Error:
assert 'testproj' in <generator object Path.iterdir at ...>
-
Reason: This error happens because the generator returned by
iterdir()
wasnโt converted to a list or string before the assertion.- Fix: Convert
iterdir()
to a list (e.g.,list((tmp_path / "projects").iterdir())
) before checking for the presence oftestproj
.
- Fix: Convert
c. test_list_projects_empty
and test_list_projects
-
Error:
assert 'No projects found' in 'No projects directory found.'
-
Reason: It seems like thereโs a mismatch between the expected error message (
'No projects found'
) and whatโs being printed ('No projects directory found.'
).- Fix: Update the assertion to match the correct output, e.g.,
assert 'No projects directory found' in result.output
.
- Fix: Update the assertion to match the correct output, e.g.,
d. test_set_and_get_config
-
Error:
assert 2 == 0
-
Reason: Similar to the first error, this suggests that the
exit_code
is not returning0
as expected, possibly due to a misconfiguration or command issue.- Fix: Investigate why
config
is returningSystemExit(2)
instead of0
.
- Fix: Investigate why
e. test_double_init_is_safe
-
Error:
assert 'created' in '[?] Initialized project: proj1\n'
-
Reason: The text in the result does not match the assertion.
- Fix: The text might need to be adjusted for case sensitivity or exact match (e.g., check if it's
'initialized'
instead of'created'
).
- Fix: The text might need to be adjusted for case sensitivity or exact match (e.g., check if it's
f. test_config_on_nonexistent_project
-
Error: The expected output (
'not exist' or 'config not found'
) isn't in the result. -
Reason: This error message suggests that the
--project
flag isnโt recognized, possibly due to a missing or incorrect option in the command.- Fix: Ensure that the
--project
flag is correctly implemented and recognized in the command.
- Fix: Ensure that the
g. test_nested_key_in_config
-
Error:
ModuleNotFoundError: No module named 'tomllib'
-
Reason:
tomllib
is available in Python 3.11 and later, but not in earlier versions like Python 3.10.- Fix: If your project must support Python 3.10, consider using
toml
ortomli
instead, or add a conditional import fortomllib
only if Python 3.11 or later is used.
- Fix: If your project must support Python 3.10, consider using
2. HTML Coverage Report
The coverage report seems to have been generated successfully despite the test failures, and it's located at C:\Users\george.bennett\OneDrive - City of Memphis\Documents\Dev\mulchcli\htmlcov\index.html
. You can open this HTML file to inspect the coverage details.
3. Logs Not Saved to Markdown
Since you mentioned the log saving is not critical, I'll leave that for now. However, it might be helpful to check if thereโs a permission issue or other reason the logs couldn't be saved to the specified location.
Next Steps:
-
Address Test Failures: Review the failing tests, starting with the most critical errors (e.g., the
SystemExit(2)
issues). You may need to adjust the test expectations or ensure the commands themselves are properly handling the inputs. -
Fix
tomllib
Import: If you're targeting Python 3.10, switch to usingtomli
or add conditional imports for compatibility. -
Check for Output Mismatches: For the tests that check output, verify the exact text being printed by the commands, as some of the expected error messages don't match what's actually being returned.
Once you've fixed the errors, rerun the tests to see if any additional issues pop up.

Query 59:
I changed python versions, with
poetry env use 3.11.9
Now that I am on 3.11.9, I think the toml issues are resolved.
(paste PowerShell errors from poetry run python run_tests.py)
ChatGPT 59:
It looks like several tests are failing. Here's a quick breakdown of what might be causing the issues:
-
test_version_command
: TheSystemExit(2)
suggests that there is a command-line argument issue (probably the--version
flag). This could mean the command is not correctly implemented or the testing environment is not invoking it as expected. -
test_init_creates_project
: The assertion fails because it tries to check if the project directory was created, but the generator object (Path.iterdir
) is being compared to a string. You may need to explicitly convert the generator to a list or loop through the items. -
test_list_projects_empty
&test_list_projects
: Both tests expect a message regarding project directories, but the output indicates "No projects directory found." This might suggest that the test setup for directories is incomplete, or there might be a mismatch in expected messages. -
test_set_and_get_config
: TheSystemExit(2)
error suggests an issue with the--project
option or other CLI parameters. This could be a missing or incorrect argument passed to the CLI command. -
test_double_init_is_safe
: The test fails because the string "created" isn't found in the output, even though the project is initialized. It seems like there's a case mismatch or different phrasing in the output message. -
test_config_on_nonexistent_project
: This failure seems to be caused by a missing or unrecognized--project
flag in the command. The error message indicates that the option is not recognized, which may mean a mismatch in the code or test expectations. -
test_nested_key_in_config
: The config file does not exist where it's expected to be. This might be a result of improper directory creation or file path issues during the test.
Next Steps:
-
Review the CLI command implementations to ensure the expected behavior matches the tests (e.g., handling
--project
,--version
, and proper directory structure). -
Check for directory creation during tests and ensure all paths are set up correctly.
-
Update test expectations based on the actual output of your CLI commands (e.g., case sensitivity in messages).
Would you like to focus on resolving one of these specific issues?
Query 60:
(paste in the three .py files from /mulchcli/tests/)
Chat GPT 60:
Here are some notes and considerations for the tests in the provided files:
1. Test File: test_cli.py
-
test_version_command: Verifies that the
--version
command correctly returns the version of themulchcli
tool. The test checks if the output contains "mulchcli" and has an exit code of0
. -
test_help_command: Ensures that the
--help
command out---uts useful help information. It checks that the result contains the word "Usage" to confirm the presence of a help message. -
test_init_creates_project: Tests that the
init
command creates a project directory. The test asserts that the specified project directory exists after invoking theinit
command. -
test_list_projects_empty: Checks that the
list-projects
command correctly handles an empty project directory. It asserts that the output includes "No projects found." -
test_list_projects: Verifies that the
list-projects
command lists a project correctly when one exists in the project directory.
2. Test File: test_config.py
-
test_set_and_get_config: This test covers setting and getting configuration values. It checks that:
-
A config file is created for a project.
-
A specific configuration value is set and successfully retrieved from the config file.
This test uses a fixture to set up a temporary project and config directory structure before running the commands.
-
3. Test File: test_edge_cases.py
-
test_double_init_is_safe: Tests the idempotency of the
init
command by ensuring that callinginit
on an already existing project does not cause errors and correctly informs the user that the project already exists. -
test_config_on_nonexistent_project: Verifies that attempting to set a configuration value on a nonexistent project correctly returns an error message about the project not existing.
-
test_nested_key_in_config: Checks that nested keys in the config file are handled correctly. It ensures that nested keys like
app.db.settings.host
are properly parsed and set in the TOML configuration file.
General Notes:
-
Edge Cases:
-
The edge case tests are well-thought-out, covering scenarios like attempting to create a project that already exists or working with non-existent projects.
-
Ensure that errors are handled gracefully with appropriate user messages when commands like
init
orconfig set
are used in improper contexts (e.g., on non-existent projects).
-
-
Isolated Filesystem:
- All tests use
CliRunner
'sisolated_filesystem
to ensure that each test runs in a clean, isolated environment. This prevents side effects between tests and guarantees reproducibility.
- All tests use
-
Expanding Edge Cases:
- It could be beneficial to add more edge case tests related to input validation (e.g., invalid characters in project names, config keys, or command arguments). This ensures that the application can gracefully handle improper user input.
Would you like any additional edge case scenarios or more comprehensive assertions to be added to these tests?
Let's break down the disparities between the test files as they are and the way they should ideally work based on the issues you're facing.
1. test_version_command
Current Issue:
- The test fails with a
SystemExit(2)
, which suggests that the--version
flag is either not correctly implemented in themain
function or that the test setup does not invoke the command as expected.
What Should Be:
-
The
--version
flag should be a valid option that outputs the version of the tool (in this case,mulchcli
). -
The test should assert that the version information is present in the output, and the exit code should be
0
(indicating success).
Possible Fixes:
-
Ensure that the
main()
function correctly handles the--version
flag. This might involve checking the argument parsing logic or ensuring the version flag is recognized in the CLI. -
Confirm that the
version
option is implemented in yourClick
CLI, usually using@click.version_option
or similar.
2. test_init_creates_project
Current Issue:
- The assertion fails because it compares a generator (
Path.iterdir()
) to a string, which will not work as expected. The generator must be converted to a list or iterated over for comparison.
What Should Be:
- The test should ensure that the project directory is created after running the
init
command. The check should look for the existence of the project directory, rather than attempting to compare the generator directly to a string.
Possible Fixes:
- Convert the
Path.iterdir()
generator to a list before performing the comparison, or useany()
or a loop to check for the presence of the project directory.
Example fix:
python
CopyEdit
assert any((tmp_path / "projects").iterdir())
3. test_list_projects_empty
& test_list_projects
Current Issue:
- Both tests fail due to a mismatch between the expected output (
No projects found
) and the actual output (No projects directory found
). The directory may not have been set up as expected, or the message formatting might be incorrect.
What Should Be:
- The tests should check for the correct message or output that indicates whether any projects are present. The test setup should ensure that the project directories are correctly created or simulated.
Possible Fixes:
-
Review the CLI implementation to ensure that the correct messages are output when no projects exist. You may need to adjust the test expectations based on the actual wording in the output.
-
Double-check if the directory structure is set up correctly before invoking the
list-projects
command in your tests.
4. test_set_and_get_config
Current Issue:
- The test fails due to a
SystemExit(2)
, which often indicates that the--project
flag or other arguments are missing or incorrectly formatted.
What Should Be:
- The
--project
option should be correctly passed to theconfig set
andconfig get
commands. The test should check that the configuration is set properly and can be retrieved afterward.
Possible Fixes:
-
Ensure that the
--project
flag is being passed correctly in both theconfig set
andconfig get
commands. -
Review how the
main()
function processes the--project
argument. It might require validation or handling that hasn't been implemented yet.
5. test_double_init_is_safe
Current Issue:
- The test fails because the string "created" isn't found in the output. This suggests that the phrasing of the success message in the CLI might be different from what the test expects.
What Should Be:
- The test should check
