Fix Bugs

Look through the GitHub issues for bugs. Anything tagged with "bug" and "help wanted" is open to whoever wants to implement it.

Implement Features

Look through the GitHub issues for features. Anything tagged with "enhancement" and "help wanted" is open to whoever wants to implement it.

Write Documentation

You can never have enough documentation! Please feel free to contribute to any part of the documentation, such as the official docs, docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

If you are proposing a feature:

• Explain in detail how it would work.
• Keep the scope as narrow as possible, to make it easier to implement.
• Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!

Ready to contribute? Here's how to set up nemseer for local development.

1. Download a copy of nemseer locally.

2. Install poetry v1.4.0

   • The command below applies to UNIX systems (Mac/Linux)

     $ curl -sSL https://install.python-poetry.org | python3 -
     

   • The command below applies to Windows. Run it in PowerShell (make sure you run PowerShell as an administrator).

     • You will also need to add the Poetry bin directory (printed during install) to your PATH environment variable

     • For activating environments etc. you may need to alter your PowerShell Execution Policy to RemoteSigned

         (Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py -
       

3. Install nemseer using poetry:

   • Developers should install additional poetry groups for development:

     • docs for documentation dependencies

     • style for linters. nemseer uses flake8 and mypy for type annotations

     • test for testing utilities

     • (optional) debug for debugging tools

       $ poetry install --with=docs,style,test
       

   • If you are on Windows and attempting to install dependencies results in an error such as the one below, refer to the fix below:

     Command "C:\Users\Abi Prakash\AppData\Local\Programs\Python\Python38\python.exe" -W ignore - errored with the following return code 1, and output:
     The system cannot find the path specified.
     C:\Users\Abi Prakash\AppData\Local\Programs\Python\Python38
     input was : import sys
     
     if hasattr(sys, "real_prefix"):
         print(sys.real_prefix)
     elif hasattr(sys, "base_prefix"):
         print(sys.base_prefix)
     else:
         print(sys.prefix)
     

   • Use the virtual env in your terminal by running poetry shell, or direct your favourite text editor to the poetry environment

4. Install the pre-commit git hook scripts that nemseer uses by running the following code within your Poetry environment (e.g. after running poetry shell)

   $ pre-commit install
   

5. Use git (or similar) to create a branch for local development and make your changes:

   $ git checkout -b name-of-your-bugfix-or-feature
   

6. When you're done making changes, check that your changes conform to any code formatting requirements and pass any tests.

7. Commit your changes and open a pull request.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

1. The pull request should include additional tests if appropriate.
2. If the pull request adds functionality, the docs should be updated.
3. The pull request should work for all currently supported operating systems and versions of Python.

Fix for running poetry on Windows

If you get an error message similar to the one above, or one that returns an EnvCommandError when you run poetry install -vv follow these steps.

We will implement the fix described here:

1. Find where poetry source files are located. We are interested in env.py.

   • They are likely to be here: C:\Users\<USER>\AppData\Roaming\pypoetry\venv\Lib\site-packages\poetry\utils
   • If they are not, run poetry install -vv to get a stack trace and find where env.py is located (this should be in the stack trace)

2. Find the _run method of class Env

3. Comment out and add lines as demonstrated below (this is done in the last three line of the code block below)

   def _run(self, cmd: list[str], **kwargs: Any) -> int | str:
   """
   Run a command inside the Python environment.
   """
   call = kwargs.pop("call", False)
   input_ = kwargs.pop("input_", None)
   env = kwargs.pop("env", dict(os.environ))
   
   try:
       #if self._is_windows:
       #    kwargs["shell"] = True
       kwargs["shell"] = False
