urequire-ab-grunt-contrib-watch

Introduction

Automagically generates and runs a grunt-contrib-watch task from a uRequire config running within grunt.

Usage

You can use this library directly or inderectly through grunt-urequire or urequire-ab-specrunner

The direct usage is :

  urequire:
    UMD:
      ...
      path: 'some/source/path'
      ...
      afterBuild: require('urequire-ab-grunt-contrib-watch')

Options

You can pass options by invoking options:

  UMD:
    path: 'some/source/path'
    afterBuild: require('urequire-ab-grunt-contrib-watch').options({
        someOption: someValue })

Watch Options blending

Note that you don't need build.watch to be set to true or anything else in your grunt-urequire config. If watch is there though, any configuration it has is blended properly into the final watch object (precedence given to options).

For example:

  UMD:
    path: 'some/source/path'
    watch: 1439
    afterBuild: require('urequire-ab-grunt-contrib-watch')

will set debounceDelay: 1439 to the options of the watch, i.e its equivalent to

  UMD:
    path: 'some/source/path'
    afterBuild: require('urequire-ab-grunt-contrib-watch').options({
        debounceDelay: 1439
    })

Also files, after and before items (see below) are carried forward and added to the final watch arrays.

debounceDelay

Sets the debounceDelay of grunt-contrib-watch

before & after tasks

You can add any other grunt (or grunt-urequire) tasks to run before or after the current task at each watch cycle:

  UMD:
    path: 'some/source/path'
    afterBuild: require('urequire-ab-grunt-contrib-watch').options
        before: ['clean:cache', 'concat:useless']                   # an `Array` of grunt tasks to run before current at each cycle
        after:  'urequire:spec zip:UMD email:me'                    # a `String` with space separated grunt tasks is also fine

You 'll be happy to know that if the task is a urequire:someTask, then its bundle.path (as a files pattern) is added to files of the grunt-contrib-watch task automatically (and the urequire build task is also initialized if not already so).

files to be watched

You can add files to the watch task grunt-contrib-watch to be watched and trigger a watch cycle if they change. They can be added in two ways:

• File patterns as defined in grunt-contrib-watch

• Some other grunt urequire:task, where its path is added so you'll never repeat your self.

Example:

 urequire:
   UMD:
     ...
     watch:
       files: ['urequire:spec', 'some/files/path/**.ext']

   spec:
     path: 'some/source/path'
     ...

In this case 'some/source/path/**/*' will be added to files along with 'some/files/path/**.ext'.

debugLevel

Prints debug info, goes from 0 (default) to 100.

All other options

Any other key is added directly to grunt-contrib-watch options object, but be warned that atBegin: true and spawn: true should not be set.
