jspreprocess-brunch v1.0.2

jspreprocess-brunch

Adds C-style preprocessor directive support to JS brunch compilations. This allows you to have the same source files, but multiple config.coffee files to compile for different environments.

Setup

Add "jspreprocess-brunch": "x.y.z" to package.json of your brunch app.

In each config.coffee file of your brunch app, add a line to specify your buildTarget.

It can also be helpful to have different public paths for each config. That way different configurations with different buildTarget's will compile their output to different folders.

ex: config_prod.coffee

exports.config =
  buildTarget: 'PRODUCTION'
  paths:
    public: 'prod'
  ...

ex: config_debug.coffee

exports.config =
  buildTarget: 'DEBUG'
  paths:
    public: 'debug'
  ...

Add Directives to Code

Directives for if, else, elif, and endif are available to control what javascript gets compiled. Each must be on its own line and prepended by the double slash comment op.

// #BRUNCH_IF (PRODUCTION)
...

// #BRUNCH_ELIF (DEBUG)
...

// #BRUNCH_ELSE
...

// #BRUNCH_ENDIF

Note the use of parentheses. Unlike C preprocessor directives, those parentheses are required for #BRUNCH_IF and #BRUNCH_ELIF statements.

The #BRUNCH_IF and #BRUNCH_ELIF directives also support the OR (||) operator. ex: // #BRUNCH_IF (PRODUCTION || iOS)

• Nested #BRUNCH_IF statements are not yet supported.

Compile Your Brunch App

Using the config_prod.coffee and config_debug.coffee examples from before, you can compile each config like so:

• brunch build -c config_prod
• brunch build -c config_debug
