This plugin requires Grunt
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 assemble-styles --save-dev
Run this task with the
grunt styles command.
Task targets, files and options may be specified according to the grunt Configuring tasks guide. ### Options
Default: empty string
Specified files will be prepended to the beginning of src files, not to the concatenated output. This feature is useful for "inlining" globaly-required LESS files, such as
mixins.less, so that they do not need to be referenced with
@import statements inside any individual files.
Concatenate all source files by default. If you change the value to false, all source files will compile into individual files.
Default: Directory of input file.
Specifies directories to scan for
@import directives when parsing. Default value is the directory of the source, which is probably what you want. In other words, the
paths option allows you to specify paths for your @import statements in the
styles task, as an alternative to specifying a path on every @import statement that appears throughout your LESS files. So instead of doing this:
you can do this:
Compress output by removing some whitespaces.
Compress output using cssmin.js
Set the parser's optimization level. The lower the number, the less nodes it will create in the tree. This could matter for debugging, or if you want to access the individual nodes in the tree.
Force evaluation of imports.
Configures -sass-debug-info support.
Accepts following values:
In your project's Gruntfile, add a section named

Pick and choose which Bootstrap components you want to "bundle" or exclude.
A common (unjustified) complaint about Bootstrap is that it's bloated or has too many "extras", which really means: "it's too much work to comment out or remove the @import statements I'm not using".
Well, lazy people rejoice! Because
assemble-styles makes it easier than squeeze cheeze to customize Bootstrap.

assemble-styles is a gruntplugin for compiling LESS to CSS, but with a twist that you won't find in other similar plugins. This plugin makes it much easier to maintain libraries of LESS components and themes, by leveraging JSON and underscore templates to enable you to define LESS "packages" or "bundles" using external configuration files.
The plugin is quite simple to use, and it demonstrates good conventions for managing your LESS components. But the best part is that you can easily switch back and forth between:
The best part is that your LESS projects will be easier to maintain.
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.
assemble-styles, and some of the documentation on this page, is derived from grunt-contrib-less, authored by Tyler Kellen. The plugin was modified to
concat LESS files first, and then compile them into CSS files. This allows for prepending globally required LESS files, and it also adds the ability to build out individual CSS files, rathers than building a single conctatenated file.
