themes-compiler-brunch

Adds support for a themes based compiling process whereby a master theme is used to create multiple additional themes that can overrride imported files to provide a completely unique theme.

Example brunch project with themeing

PROJECT FOLDER  
  app  
      /base (this is the master theme)
          /sass
          /js
      /theme2   
          /sass
          /js
      /theme3
          /sass
          /js
      ...  
  node_modules  
  brunch-config.coffee  
  package.json  
  ...  

If a file of the same name exists in another theme other than 'base' then that file will replace the file in base when compiling the css file for that theme (imports as well).

For example

PROJECT FOLDER  
  app  
      /base (this is the master theme)
          /sass  
              /partials
                  _header.scss  
              base.scss (this file imports _header.scss using import) 
      /theme2 
          /sass  
              /partials
                  _header.scss (custom _header.scss file)

Then base.scss is rendered for each theme:

FOR base 
    {output-folder}/base.css (import uses the header.scss file located in base theme when import is referenced) 
FOR theme2  
    {output-folder}/base.css (import uses the header.scss file located in theme2 theme when import is referenced)  

Example brunch-config file

exports.config =
  # See http://brunch.io/#documentation for docs.
  paths:
    public: "../../theme/static-test"
  files:
    stylesheets:
      joinTo:
        "base/css/base.css": /^app\/themes\/base\/sass\/base.*/
    javascripts:
      joinTo:
        "base/js/app.js": /^app\/themes\/base\/js/
        "base/js/vendor.js": /^app\/themes\/base\/vendor/
  overrides:
    theme1:
      files:
        stylesheets:
          joinTo:
            "theme1/css/base.css": /^app\/themes\/base\/sass\/base.*/
        javascripts:
          joinTo:
            "theme1/js/app.js": /^app\/themes\/carbon\/js/
            "theme1/js/vendor.js": /^app\/themes\/carbon\/vendor/
    theme2:
      files:
        stylesheets:
          joinTo:
            "theme2/css/base.css": /^app\/themes\/base\/sass\/base.*/
        javascripts:
          joinTo:
            "theme2/js/app.js": /^app\/themes\/krypton\/js/
            "theme2/js/vendor.js": /^app\/themes\/krypton\/vendor/
  plugins:
    themes:
      options:
        directory: 'themes'
        base: 'base'
        styles: 'sass'

###To build:###

• base - brunch build
• theme1 - brunch build --env theme1
• theme2 - brunch build --env theme2

Known Issues

• Currently file import substition only works with scss not sass due to pattern matching error
• Had to circumvent brunch pipline callback on compile due to being unable to control multiple files being written based on single path passed to compile.
