Linter Cheatsheet

It happens to be a major PITA to find these little snippets, so I gather all useful findings here. As a rule of thumb, you should use these as last resort to solve a linting issue.

_* Some JSlint suppressors work with JSHint, YMMV. For JShint/JSLint compatibility, space after a comment token (/_) must be omitted.

ESLint

http://eslint.org/docs/rules/

  • Suppress all
/* eslint-disable */
  • Suppress all for a single line
// eslint-disable-line
  • Suppress a rule for a single line
// eslint-disable-line <rule1> <rule2>
  • Suppress a rule for all
/* eslint-disable <rule> */ E.g.: /* eslint-disable space-before-function-paren */

JShint

http://jshint.com/docs/options/

  • Suppress environment warnings
// jslint browser: true
// jslint jquery: true
// jshint esversion: 6
  • Suppress undefined global variables. **
/*global <var1>, <var2>, ... */
  • Suppress exported/unused global variables. **
/*exported <var1>, <var2>, ... */
  • Suppress a single warning. E.g.: // jshint -W001
// jshint -<*>
// jshint +<*>
  • Suppress all warnings
// jshint ignore:start
// jshint ignore:end
  • Suppress all warnings for a single line
// jshint ignore:line

HTML-Lint

Rules

<!--htmlhint spec-char-escape: false -->

SCSS-Lint

  • Suppress a single warning. Example: // scss-lint:enable Compass::PropertyWithMixin
// scss-lint:enable <*>
// scss-lint:disable <*>

Pug-lint (was Jade)

https://github.com/pugjs/pug-lint/blob/master/docs/rules.md

Beautify

  • Suppress through a section (must be a block-comment)
/* beautify ignore:start */
/* beautify ignore:end */
