custolint 0.4.6

Another custom linter layer

Your current code-validation pipeline rules may be changed more easily using custolint.

Source Code: https://github.com/a-da/custolint.

Custolint add new layer on top of:

• PyLint

• Flake8

• MyPy

• Python Coverage

Motivation

You cannot just add a linter and activate 100% inspections when you have a large, ancient codebase with thousands of lines.

Instead, you only make 1% of the checks available, which is really frustrating for a decent developer.

You could enable those 100% checks just for your changes with “custolint”.

Idea

Given we have a project alike this one, where we:

1. had added a function custolint/generics.py:filer_output.

2. had modified the function custolint/git.py:_blame

$ tree
...
|-- src
|   |-- custolint
...
|   |   |-- generics.py <<<< 1
|   |   |-- git.py      <<<< 2
|   |   |-- mypy.py
|   |   |-- pylint.py
|   |   `-- typing.py
|-- tests
|   `-- test_custolint.py
...

When:

• Detect affected files with git diff and git blame

  • custolint/git.py

  • custolint/generics.py

• Run the linter tool (pylint, flake8, mypy, coverage …) with all available feature enables (the configuration have to be placed into config.d/ folder) only on changed affected files or parse log/result of the linter tool.

• Match changed code with the linters output, and consider only the match lines as failed lint criteria. It has to detect that custolint/generics.py:filer_output need unitest for coverage and custolint/git.py:_blame introduce a mypy typing issue.

Then:

• Fail or Report the build.
