There are so many excellent coverage badge generation tools out there, why do we need another one? Well, at the time of writing this package (circa early 2021), all the existing tools (for example, coverage-badge) I had come across ended at generating SVG/PNG files/strings/Base64 images. What you do with this remains entirely up to you.

Now, it is often much easier to simply use online services such as codecov.io and coveralls.io. These services are free for open source projects, but require a monthly subscription for private repos. Many times, we work on private repos, and we wanna be able to automatically have coverage badges in our READMEs. What if you are unable to pay such subscription fees, or maybe you don't want to use a SaaS? Your solution becomes to generate your own badge!

This is where this project comes in. It automatically generates your project's coverage badge using the shields.io service, and then updates your README accordingly, in just one command! That's all it does, resonating with the Unix philosophy of doing one thing and doing it well. The main idea for this came from istanbul-badges-readme, which does exactly the same thing for JavaScript projects. You will see that these two projects have quite a lot in common.

After using istanbul-badges-readme, I searched for a python alternative but couldn't find anything suitable. The closest I found was coverage-badge, and if you look at this project's code, you will see a lot of similarities with coverage-badge!

If what you're looking for is a powerful, general purpose badge generation tool for your projects, then you should probably check out projects like anybadge and genbadge.

• automatically generates your project's coverage badge using the shields.io service, and then updates your project's README with the newly generated badge
• simple CLI tool (readme-cov) with helpful messages
• tested on python 3.6 to 3.9 with coverage ≥ 84%
• free software: BSD-3-Clause license
• generates different colours depending on the coverage percentage. Optionally generate plain colour (green) regardless of percentage
• minimal external dependencies – this tool only has 2 external dependencies; Coverage.py (obviously!) and colorama (for cross-platform coloured terminal output)

The table below shows the coverage thresholds, associated colours and examples of generated badges:

Coverage	Colour	Example
0 ≤ coverage < 40	red
40 ≤ coverage < 60	orange
60 ≤ coverage < 75	yellow
75 ≤ coverage < 90	yellowgreen
90 ≤ coverage < 95	green
95 ≤ coverage ≤ 100	brightgreen

pip install readme-coverage-badger

Note: Before using the tool, ensure that you insert a string of the form ![Code Coverage]() or ![Code Coverage](anything here) in your project's README.

readme-cov [-h] [-v] [-p]

optional arguments:
  -h, --help     show the help message and exit
  -v, --version  show program's version number and exit
  -p, --plain    Plain colour mode. Standard green badge.

The tool operates on the basis of the following assumptions:

• you have a README.md or README file at the root of your project
• your README file is in markdown format. I know, some Pythonistas prefer restructuredtext! Sadly, this isn't supported (yet)
• Somewhere in your your README is a string in the form: ![Code Coverage]() or ![Code Coverage](anything here). This is what gets updated in-place (using re.sub()) when the script runs.
• the script is called from the root of your project repo, which has coverage.py already configured, and the coverage already updated (you have already run your tests prior to running the script)
• If the coverage badge in your README file is already up to date, your README file won't be updated, you will only be notified

• ensure that you have Python 3.6+ on your machine, and that you are able to configure python virtual environments.
• ensure that you have git setup on your machine.

First, fork this repository, then fire up your command prompt and ...

1. Clone the forked repository
2. Navigate to the cloned project directory: cd readme_coverage_badger
3. activate your python virtual environment and pip install --upgrade pip
4. Install dependencies: pip install -r requirements_dev.txt
5. Setup pre-commit by running pre-commit install followed by pre-commit install --hook-type commit-msg. Optionally run pre-commit run --all-files to make sure your pre-commit setup is okay.

At this stage, hopefully everything should be working fine, and you should be able to start hacking on the project.

You can run the application via invoke run or

python readme_coverage_badger/__main__.py

Simply run pytest or invoke test to run tests in your virtual environment.

Test other Python versions by running tox.

• Run invoke lint to run flake8, black, isort and mypy on the code.
• If you get any errors from black and/or isort, run invoke lint --fix or invoke lint -f so that black and isort can format your files. Alternatively, just run pre-commit. You can take a look at .pre-commit-config.yaml.

Contributions, issues and feature requests are most welcome! A good place to start is by helping out with the unchecked items in the TODO section of this README!

Feel free to check the issues page and take a look at the contributing guide before you get started. In addition, please note the following:

• if you're making code contributions, please try and write some tests to accompany your code, and ensure that the tests pass. Also, were necessary, update the docs so that they reflect your changes.
• commit your changes via cz commit. Follow the prompts. When you're done, pre-commit will be invoked to ensure that your contributions and commits follow defined conventions. See pre-commit-config.yaml for more details.
• your commit messages should follow the conventions described here. Write your commit message in the imperative: "Fix bug" and not "Fixed bug" or "Fixes bug." This convention matches up with commit messages generated by commands like git merge and git revert. Once you are done, please create a pull request.

Please give a ⭐️ if this project helped you!

• Cater for not only markdown but also restructuredtext, and automatically detect if a file's syntax is markdown or restructuredtext if no extension given
• Provide option to generate badge in HTML format
• Provide option to generate to stdout and skip substitution in a README file. This could be useful if you're using the tool in a script and you just want the result so that you can use it elsewhere.
• Allow for flexibility in choosing whatever colours one wants
• Allow for specifying Alt Text on the badge URL, for example ![Alt Text]() or ![Alt Text](anything here)
• Make the codebase fully typed
• Improve the Tests by parametrizing fixtures and test functions
• improve CI/CD to cater for GNU/Linux, Mac OS X and Windows
• Create pre-commit hook

• Add a screenshot / demo in this README
• Create standalone documentation for hosting either on Github Pages or readthedocs. This README is already detailed enough to serve as documentation!

• It would be fun if we had some kind of a badger logo!
