mylint

My really simple rendition of how a linter works.

This original version was written for my AST article. Since then I've added tests and turned it into a package. Check the original branch for the original version of this, that was used in the article.

Usage

mylint [...file names]

Example:

$ mylint tests/testcode.py
testcode.py:17:15: W001: Set contains duplicate item: 1
testcode.py:12:12: W001: Set contains duplicate item: 'PUT'
testcode.py:1:0: W002: Unused variable: 's'
testcode.py:5:4: W002: Unused variable: 'var'
testcode.py:17:0: W002: Unused variable: 's2'

Development / Testing

Setup a virtual environment, and install the package with:

pip install -r requirements-dev.txt

Then run pytest to run tests. Now, have fun playing with the code and tests!

Type Checking

Run mypy .
