Install the LESS command line compiler, JSHint, Recess, and uglify-js globally with npm by running the following command:
$ npm install -g less jshint recess uglify-js
Once installed just run make
from the root of your bootstrap directory and you're all set.
Additionally, if you have watchr installed, you may run make watch
to have bootstrap automatically rebuilt every time you edit a file in the bootstrap lib (this isn't required, just a convenience method).
Install the LESS command line tool via Node and run the following command:
$ lessc ./less/bootstrap.less > bootstrap.css
Be sure to include --compress
in that command if you're trying to save some bytes!
Download the latest Less.js and include the path to it (and Bootstrap) in the <head>
.
<link rel="stylesheet/less" href="/path/to/bootstrap.less"> <script src="/path/to/less.js"></script>
To recompile the .less files, just save them and reload your page. Less.js compiles them and stores them in local storage.
The unofficial Mac app watches directories of .less files and compiles the code to local files after every save of a watched .less file.
If you like, you can toggle preferences in the app for automatic minifying and which directory the compiled files end up in.
Crunch is a great looking LESS editor and compiler built on Adobe Air.
Created by the same guy as the unofficial Mac app, CodeKit is a Mac app that compiles LESS, SASS, Stylus, and CoffeeScript.
Mac, Linux, and PC app for drag and drop compiling of LESS files. Plus, the source code is on GitHub.
