grunt-flake8

library0.1.3jsnpmunverified

A Grunt plugin to lint Python projects using flake8, which combines PyFlakes, PEP8, and McCabe's cyclomatic complexity checks. Version 0.1.3, last released in 2014, with no active development. It wraps flake8 as a Grunt task, allowing project-level configuration overrides. Alternatives include direct flake8 invocation or other Python linters.

// Install: npm install grunt-flake8 --save-dev // Gruntfile.js module.exports = function(grunt) { grunt.initConfig({ flake8: { options: { errorsOnly: false, force: false, maxComplexity: 10, maxLineLength: 100, ignore: ['E501'] }, src: ['src/**/*.py', 'test/**/*.py'] } }); grunt.loadNpmTasks('grunt-flake8'); grunt.registerTask('default', ['flake8']); };

Debug

Known issues

deprecatedPackage has not been updated since 2014; unmaintained.

fix

Use direct flake8 invocation or switch to modern Python linting tools.

affects: >=0.1.0

gotchaGrunt must be run from within the Python virtual environment where flake8 is installed.

fix

Activate the virtual environment before running grunt.

affects: >=0.1.0

gotchaOptions set in Gruntfile override global/project flake8 configurations; some options may be dropped silently.

fix

Check flake8 documentation for supported options and test with --verbose.

affects: >=0.1.0
