grunt-passfail

Run functions when your tasks complete or fail.

Getting Started

This plugin requires Grunt ~0.4.1

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-passfail --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-passfail');

The "passfail" task

Overview

In your project's Gruntfile, add a section named passfail to the data object passed into grunt.initConfig().

grunt.initConfig({
  passfail: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
})

Options

All callbacks called in task context, giving you access to the "inside tasks" API: http://gruntjs.com/api/inside-tasks

Could be useful, for example, to run async logic with this.async

options.force

read this!

Type: Boolean Default value: false

Alias for the --force option on the command line. Defaults to false. This plugin won't work without force, since it will presumably be the last task run and will never be run if a previous task fails without --force set.

This is just a convenience so you don't have to supply --force all the time, but beware! It'll force --force on all your tasks! force force :O

options.fail

Type: Function

A function to be run when at least one warning or error has occured anywhere in the current task. Is passed the number of warnings and errors occurred.

callback(warncount, errorcount)

options.success

Type: Function

A function to be run when no errors nor warnings have occurred. Also, the options ignoreWarn and ignoreError can be supplied to affect the condition on which success is callled.

options.error

Type: Function

A function to be run when at least one error has occurred in the current task. It is passed the number of errors occurred.

callback(errorcount)

options.warn

Type: Function

A function to be run when at least one warning has occurred in the current task. It is passed the number of warnings occurred.

callback(warncount)

options.ignoreWarn

Type: Boolean Default: false

If set to true, warnings will not affect whether the success function will be run.

options.ignoreError

Type: Boolean Default: false

If set to true, errors will not affect whether the success function will be run.

Usage Examples

grunt.initConfig({
  passfail: {
    options: {
      force: true
    },
    all: {
      success: function() {
        console.log("Cool :)")
      },
      fail: function() {
        console.log("Lame :'(")
      }
    }
  }
})

Here's an example using SoX to play an mp3

var spawn = require('child_process').spawn;

grunt.initConfig({
  passfail: {
    options: {
      force: true
    },
    all: {
      success: function() {
        spawn('play', ['./success.mp3']).on('close', this.async());
      },
      fail: function() {
        spawn('play', ['./fail.mp3']).on('close', this.async());
      }
    }
  }
})

Possible TODOs

  • Use this.requires for success / fail checking?
  • Allow customizable success and failure conditions?
