Utility for examining python source files to ensure proper documentation. Lists missing docstrings, and calculates overall docstring coverage percentage rating
If the health of your documentation is in dire straits, `docstr-coverage` will see you now.
`docstr-coverage` is a simple tool that lets you measure your Python source code's
[docstring](http://www.python.org/dev/peps/pep-0257/#what-is-a-docstring) coverage. It can show you which of your functions,
classes, methods, and modules don't have docstrings. It also provide statistics about overall docstring coverage for individual
files, and for your entire project.

- No module docstring
- No docstring for `readme`
Needed: 2; Found: 0; Missing: 2; Coverage: 0.0%
- No module docstring
Needed: 1; Found: 0; Missing: 1; Coverage: 0.0%
- No docstring for `DocStringCoverageVisitor.__init__`
Needed: 11; Found: 10; Missing: 1; Coverage: 90.9%
Overall statistics for 3 files:
Docstrings needed: 14; Docstrings found: 10; Docstrings missing: 4
Total docstring coverage: 71.4%; Grade: Very good
How Do I Use It?
#### Command-line Tool
General usage is: `docstr-coverage <path to dir or module> [options]`
To test a single module, named `some_module.py`, run:
$ docstr-coverage some_module.py
To test a directory (recursively), just supply the directory `some_project/src` instead:
$ docstr-coverage some_project/src
* *--skipmagic, -m* - Ignore all magic methods (like `__init__`, and `__str__`)
* *--skipfiledoc, -f* - Ignore module docstrings (at the top of files)
* *--exclude=\<regex\>, -e \<regex\>* - Filepath pattern to exclude from analysis
* To exclude the contents of a virtual environment `env` and your `tests` directory, run:
<br>```$ docstr-coverage some_project/ -e "env/*|tests/*"```
* *--verbose=\<level\>, -v \<level\>* - Set verbosity level (0-3)
* 0 - Silence
* 1 - Print overall statistics
* 2 - Also print individual statistics for each file
* 3 - Also print missing docstrings (function names, class names, etc.)
#### Package in Your Project
You can also use `docstr-coverage` as a part of your project by importing it thusly:
from docstr_coverage import get_docstring_coverage
my_coverage = get_docstring_coverage(['some_dir/file_0.py', 'some_dir/file_1.py'])
* Required arg: `filenames` \<list of string filenames\>
* Optional kwargs: `skip_magic` \<bool\>, `skip_file_docstring` \<bool\>, `verbose` \<int (0-3)\>
* For more info on `get_docstring_coverage` and its parameters, please see its [documentation](https://docstr-coverage.readthedocs.io/en/latest/api_essentials.html#get-docstring-coverage)
```get_docstring_coverage``` returns two dicts: 1) stats for each file, and 2) total stats.
For more info, please see the `get_docstring_coverage` [documentation](https://docstr-coverage.readthedocs.io/en/latest/api_essentials.html#get-docstring-coverage)
Why Should I Use It?
* Thorough documentation is important to help others (and even yourself) understand your code
* As a developer, improve your code's maintainability for when you need to make updates and fix bugs
* As a user, instantly know how easy it's going to be to understand a new library
* If its documentation coverage is low, you may need to figure a lot out for yourself
