grunt-git-describe

> Describes git commit

Getting Started

This plugin requires Grunt ~0.4.0

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:

``shell
npm install grunt-git-describe --save-dev
`

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

`js
grunt.loadNpmTasks('grunt-git-describe');
`

The "git-describe" task

$3

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

`js
grunt.initConfig({
"git-describe": {
"options": {
// Task-specific options go here.
},
"your_target": {
// Target-specific file lists and/or options go here.
},
},
})
`

> Note that since this is a multi-task you have to have at least one target defined for git-describe (otherwise the task won't run)

$3

#### options.cwd
Type: String
Default value: '.'

A string value that is used to do set the current working directory when spawning the git command

#### options.commitish
Type: String
Default value: undefined

A string value that is used as commitish for git. Default is to use HEAD.

$3

Type: String
Default value: {%=tag%}-{%=since%}-{%=object%}{%=dirty%}

A string value used to format the result of this task

#### options.match
Type: String
Default value: undefined

Value for the --match command line option. If set, only consider tags matching this glob pattern, excluding the "refs/tags/" prefix.

#### options.failOnError
Type: boolean
Default value: true

A boolean that allows Grunt to keep going if there's an error in this task. This is useful if your build isn't guaranteed to always be run from within a Git repo.

$3

If you would like to save or otherwise use the retun value, use grunt.event.emit. Here is an example:
`js
grunt.registerTask('saveRevision', function() {
grunt.event.once('git-describe', function (rev) {
grunt.log.writeln("Git Revision: " + rev);
grunt.option('gitRevision', rev);
});
grunt.task.run('git-describe');
});
`

#### Returned Object
The rev object returned makes several specific properties available, in addition to the full toString description.
`js
grunt.event.once('git-describe', function (rev) {
grunt.log.writeln("Git rev tag: " + rev.tag);
grunt.log.writeln("Git rev since: " + rev.since);
grunt.log.writeln("Git rev object: " + rev.object); // The 6 character commit SHA by itself
grunt.log.writeln("Git rev dirty: " + rev.dirty); // A flag denoting whether all local changes are committed
});
