stylelint-scss - A collection of SCSS specific linting rules for stylelint

•    Javascript

---

A collection of SCSS specific linting rules for stylelint (in a form of a plugin). stylelint by itself supports SCSS syntax very well (as well as other preprocessors' syntaxes). Moreover, it introduces some specific rules that can be used to lint SCSS, e.g. to limit nesting, control the way @-rules are written. Yet stylelint is in general focused on standard CSS.

stylelint-webpack-plugin - A webpack plugin to lint your CSS/Sass code using stylelint

•    Javascript

---

This module requires a minimum of Node v6.9.0 and webpack v4.0.0. Both stylelint-loader and this module have their uses. stylelint-loader lints the files you require (or the ones you define as an entry in your webpack config). However, @imports in files are not followed, meaning only the main file for each require/entry is linted.

scss-lint - Configurable tool for writing clean and consistent SCSS

•    Ruby

---

scss-lint is a tool to help keep your SCSS files clean and readable by running it against a collection of configurable linter rules. You can run it manually from the command line, or integrate it into your SCM hooks. The Sass core team is now building Sass in Dart instead of Ruby, and will no longer be maintaining the Ruby implementation unless a maintainer steps up to help. Since the SCSS-Lint project relies on the Ruby Sass implementation, this means it will eventually not support the latest Sass features and bug fixes.

sass-lint - Pure Node.js Sass linting

•    Javascript

---

Sass-lint can be configured from a .sass-lint.yml or .sasslintrc file in your project. The .sasslintrc file can be in either JSON format or YAML. Both formats are interchangeable easily using tools such as json2yaml. If you don't either file in the root of your project or you would like all your projects to follow a standard config file then you can specify the path to one in your project's package.json file with the sasslintConfig option. Use the Sample Config (YAML) or Sample Config (JSON) as a guide to create your own config file. The default configuration can be found here.

syntastic - Syntax checking hacks for vim

•    Vim

---

Syntastic is a syntax checking plugin for Vim created by Martin Grenfell. It runs files through external syntax checkers and displays any resulting errors to the user. This can be done on demand, or automatically as files are saved. If syntax errors are detected, the user is notified and is happy because they didn't have to compile their code or execute their script to find them. At the time of this writing, syntastic has checking plugins for ACPI Source Language, ActionScript, Ada, Ansible configurations, API Blueprint, AppleScript, AsciiDoc, Assembly languages, BEMHTML, Bro, Bourne shell, C, C++, C#, Cabal, Chef, CMake, CoffeeScript, Coco, Coq, CSS, Cucumber, CUDA, D, Dart, DocBook, Dockerfile, Dust, Elixir, Erlang, eRuby, Fortran, Gentoo metadata, GLSL, Go, Haml, Haskell, Haxe, Handlebars, HSS, HTML, Java, JavaScript, JSON, JSX, Julia, LESS, Lex, Limbo, LISP, LLVM intermediate language, Lua, Markdown, MATLAB, Mercury, NASM, Nix, Objective-C, Objective-C++, OCaml, Perl, Perl 6, Perl POD, PHP, gettext Portable Object, OS X and iOS property lists, Pug (formerly Jade), Puppet, Python, QML, R, Racket, RDF TriG, RDF Turtle, Relax NG, reStructuredText, RPM spec, Ruby, SASS/SCSS, Scala, Slim, SML, Solidity, Sphinx, SQL, Stylus, Tcl, TeX, Texinfo, Twig, TypeScript, Vala, Verilog, VHDL, Vim help, VimL, Vue.js, xHtml, XML, XSLT, XQuery, YACC, YAML, YANG data models, YARA rules, z80, Zope page templates, and Zsh.

lint-staged - 🚫💩 — Run linters on git staged files

•    Javascript

---

Linting makes more sense when running before committing your code. By doing that you can ensure no errors are going into repository and enforce code style. But running a lint process on a whole project is slow and linting results can be irrelevant. Ultimately you only want to lint files that will be committed. This project contains a script that will run arbitrary npm and shell tasks with a list of staged files as an argument, filtered by a specified glob pattern.

ember-paper - The Ember approach to Material Design.

•    Javascript

This project aims to bring Google's new Material Design to Ember. The goal is to encapsulate everything possible in Ember components. This project is packaged as an Ember-cli addon. This should also automatically create an scss file under app/styles/app.scss with @import 'ember-paper'; and install ember-cli-sass.

puppet-lint - Check that your Puppet manifests conform to the style guide

•    Ruby

---

Puppet Lint tests Puppet code against the recommended Puppet language style guide. Puppet Lint validates only code style; it does not validate syntax. To test syntax, use Puppet's puppet parser validate command. Puppet Lint version 2 is the last planned version with support for Puppet 3 and Ruby 1.8.7. The next major version of Puppet Lint will drop support for these versions.

ruby-lint - Moved to https://gitlab.com/yorickpeterse/ruby-lint

•    Ruby

---

ruby-lint is a static code analysis tool for Ruby. It is inspired by tools such as jshint, flake8 and similar tools. ruby-lint primarily focuses on logic related errors such as the use of non existing variables instead of focusing on semantics (e.g. the amount of characters per line). The features of ruby-lint include but are not limited to the detection of unused variables, the use of undefined methods and method calls with invalid argument amounts and more. More in-depth analysis will be added over time.
