grunt-lesshint

Lint LESSCSS files with grunt

Getting Started

This plugin requires Grunt ~0.4.5

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-lesshint --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks( 'grunt-lesshint' );

The "lesshint" task

Overview

In your project's Gruntfile, add a section named lesshint to the data object passed into grunt.initConfig().

grunt.initConfig({
    lesshint: {
        options: {
            // Task-specific options go here.
        },
        your_target: {
            // Target-specific file lists and/or options go here.
        },
    },
});

Options

force

Type: Boolean
Default value: false

Set force to true to report lesshint errors but not fail the task.

reporter

Type: Object

Refer to the lesshint docs for more examples: https://github.com/lesshint/lesshint#writing-your-own-reporter Define your own custom reporter:

options {
    reporter: {
        name: "foo-reporter", // optional but recommended
        report: function(errors) {
            errors.forEach(function(error) {
                console.log(error);
                // error object looks like:
                // {
                //     column: 5,
                //     file: 'file.less',
                //     fullPath: 'path/to/file.less',
                //     line: 1,
                //     linter: 'spaceBeforeBrace',
                //     message: 'Opening curly brace should be preceded by one space.',
                //     severity: 'warning',
                //     source: '.foo{'
                // }
            });
        }
    }
}

lesshintrc

Type: String or true
Default: null

If set to true, no config will be sent to lesshint and lesshint will search for .lesshintrc files relative to the files being linted.

If a filename is specified, options and globals defined therein will be used. The lesshintrc file must be valid JSON and looks something like this:

{
    "spaceAfterPropertyColon": "no_space",
    "spaceBeforeBrace": "no_space"
}

allowWarnings

Type: Boolean
Default value: false

Set allowWarnings to true to allow the task to succeed if only warnings occur.

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
