    Perfect, that worked, thank you!

    I thought this could be solved by changing the directory to src/ and then executing that command, but this didn't work.

    This also seems to be an issue with the web app, e.g. the repository for the formatter black is only one white dot

    Ruff is not only much faster, but it is also very convenient to have an all-in-one solution that replaces multiple other widely used tools: Flake8 (linter), isort (imports sorting), Black (code formatter), autoflake, many Flake8 plugins and more. And it has drop-in parity with these tools, so it is really straightforward to migrate from them to Ruff.

    1. LICENSE: This file contains information about the rights and permissions granted to users regarding the use, modification, distribution, and sharing of the software. I already had an MIT License in my project. 2. pyproject.toml: It is a configuration file typically used for specifying build requirements and backend build systems for Python projects. I was already using this file for Black code formatter configuration. 3. Used as a documentation file for your project, typically includes project overview, installation instructions and optionally, contribution instructions. 4. example_package_YOUR_USERNAME_HERE: One big change I had to face was restructuring my project, essentially packaging all files in this directory. The name of this directory should be what you want to name your package and shoud not conflict with any of the existing packages. Of course, since its a Python Package, it needs to have an 5. tests/: This is where you put all your unit and integration tests, I think its optional as not all projects will have tests. The rest of the project remains as is.

    It was with this test that I made that I was able to test my parse_md function, previously called check_md_and_write, and locate a bug that I uncovered a last week. I noticed this bug when I was using the linter, Ruff, and formatter, Black, I set up for my project. If you're interested in reading about the linter and formatter I chose and the setup process you can read last week's blog. Essentially the problem was that I could not parse any Markdown in my program. I wasn't sure what the problem was, but I think it had something to do with when I refactored my code and tried to clean things up. Luckily, I still has the branches where I worked on improved the function to parse markdown and the refactoring branch. To make note of it, I made an issue for myself and specified which branches to take a look at.
