grunt-bless

A grunt module for Blessing your CSS files so they will work in Internet Explorer. This is based on a pull request by Aki Alexandra Nofftz (@akinofftz).

Getting Started

This plugin requires Grunt >=0.4.0

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-bless --save-dev

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

grunt.loadNpmTasks('grunt-bless');

The "bless" task

Overview

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

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

Options

options.banner

Type: String Default value: undefined

Add a banner followed by a new line to the top of the main file, the one that you will include in your source.

	options: {
		banner: '/* this is a banner */'
	}

options.compress

Type: Boolean Default value: false

Compress the css output added by bless. This does not compress the CSS you wrote. For that you should try the cssmin plugin.

options.force

Type: Boolean Default value: false if grunt --force flag is not set

Override the Grunt option for this task. This will allow bless to overwrite the input file.

Changed in v0.2.0, grunt-bless will refuse to overwrite the input file. To return to the old behavior, set this option to true.

options.imports

Type: Boolean Default value: true

Enable or disable the use of @import in generated CSS files. This feature was added in bless.js 3.0.3.

options.root

Type: String Default value: ''

Add a path or domain to the @import statements in the generated CSS files. By default the generated CSS files are relative to the output file.

options.logCount

Type: Boolean | String Default value: false

If set to true, you'll get output with all file selectors count. If set to warn, you'll get only log messages only on files that reached CSS selectors limit.

options.failOnLimit

Type: Boolean Default value: false

Requires logCount. If set to true, the process will exit with an error if the selector limit is exceeded.

options.suffix

Type: String Default value: '' Added: v1.0.0

Add a suffix to the filename. The suffix will be added before the number and only if it is not the main file.

options.sourceMaps

Type: Boolean Default value: false Added: v1.0.0

Generate sourcemaps for the provided files.

Removed options

These options have been removed from grunt-bless and no longer function.

options.cacheBuster

Type: Boolean Default value: true

Add or remove a cache-buster parameter from the generated CSS files.

Reason for removal:

• Removed in bless 4.0.0.
• Other plugins may provide better support.
• See this issue

options.cleanup

Type: Boolean Default value: true

Clean up files generated by bless before proceeding.

Reason for removal:

• Removed in bless 4.0.0.
• Other plugins may provide better support.

Usage Examples

Default Options

The default options will split the files and add a cache-buster parameter. Just as the defaults for blessc are.

grunt.initConfig({
	bless: {
		css: {
			options: {},
			files: {
				'tmp/above-limit.css': 'test/input/above-limit.css'
			}
		}
	}
})

Custom Options

You can set any option allowed by bless.

grunt.initConfig({
	bless: {
		css: {
			options: {
				cacheBuster: false,
				compress: true
			},
			files: {
				'tmp/below-limit.css': 'test/input/below-limit.css'
			}
		}
	}
})

Without writing

If you don't want to write blessed files, you can just set input files, without destination and add logging.

grunt.initConfig({
	bless: {
		css: {
			options: {
				logCount: true
			},
			src: [
				'test/input/below-limit.css'
			]
		}
	}
})

Contributing

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.
