poetry_test_project_for_me 0.2.0

A poetry python test projet

Poetry Test

In this proeject, I will be testing the poetry package manager for python.

Currently the project is capable of downloading a random image.

How to Poetry

--> https://python-poetry.org/docs/#installation

Installing Poetry

Install it via pipx install poetry.

pipx installs packages semi globally, very weird...

Setup a poetry project directory

1. Make poetry create a .venv dir for you in every project that uses poetry -> poetry config virtualenvs.in-project true (this is a global setting)
2. Run poetry init in your project dir
3. Add dependencies with poetry add <module_name> or during the init process
4. Run poetry install to install your dependencies.
5. Change the python version of your venv to the same as your poetry project via: -> poetry env use /path/to/python3.11
6. Activate your new venv via poetry shell and DO NOT source .venv/bin/activate

Local Packaging

1. Build the package via poetry build
2. Install the wheel locally: pip install dist/your_project.whl

To actually being able to run your python program, you must include this line in your pyproject.toml:

[tool.poetry.scripts]
your_command_name = "your_project_name.main:main"

Explanation:

1. your_command_name = the command you will run to start your project. Should be same as project name if you only have one.
2. your_project_name = the name of the dir in the src/ folder where your project code is
3. .main = the name of the file you want to execute
4. :main = the name of the function in the file you want to execute
5. You can actually have multiple commands here

Publishing your package to pypi

1. Run: poetry config pypi-token.pypi <YOUR_PYPI_TOKEN>
   1. This command stores the API token directly in Poetry's configuration. I don't know where since I could not read it via poetry config --list.
2. Build and Publish via: poetry publish --build

Publishing to a custom repo (untested):

1. Run poetry config pypi-token.<repository_name> <YOUR_REPOSITORY_TOKEN>
2. in your pyproject.toml add:

[tool.poetry.repositories.<repository_name>]
url = "https://example.com/my-private-repo"

3. Build and Publish: poetry publish --build -r my-private-repo

Example File Structure

simple poetry example file structure:

poetry-test/
├── pyproject.toml
├── README.md
├── src/
│   └── poetry_test/
│       ├── __init__.py
│       └── main.py
└── tests/
    └── test_example.py
