Task helpers for Cakefiles


I've always been a little frustrated with the node filesystem API, especially when trying to get a build process in place for a javascript project. Frosting is really not much more than an abstraction layer over the filesystem module that helps keep Cakefiles readable.


To skip right to some code, here's an example Cakefile with build tasks for a client-side javascript library:

{each} = require 'frosting'
task 'compile:dev''Compile development distro files'->
  each './lib/*.coffee'( f ) -> f.compile -> f.write "./dist/dev/#{f.basename( )}.js"
task 'compile:min''Compile minified distro files'->
  each './lib/*.coffee'( f ) -> f.compile -> f.minify -> f.write "./dist/min/#{f.basename( )}.js"
task 'compile''Compile all distro files'->
  invoke 'compile:dev'
  invoke 'compile:min'

Frosting is definitely an opinionated set of build tools. It assumes that source files are being written in coffeescript and minification will be done via uglify-js.

Frosting provides a couple of convenience methods that yield a File class. This class has the necessary API for reading, writing, mutating, inspecting, compiling and minifying source files.


each can be used to iterate over a set of source files. It accepts a callback which will be passed a File instance for each file, and you can build as you wish from there. It can be given a glob pattern or an explicit array of files.

each './lib/*.coffee'( f ) -> # `f` is an instance of File 
# or 
each [
]( f ) -> # `f` is an instance of File 


concat is similar to each, except it simply concatenates all of the source files into one coffeescript file and yields a File instance with the combined sources already in the buffer. If given an array of filenames, they will be read and concat'd in order.

concat './lib/*.coffee'( f ) -> # `f` is an instance of File, will only get called once 
# or 
concat [
]( f ) -> # `f` is an instance of File, will only get called once
