Sharing data between tasks

Comments

In the scenario below task2 depends on the result from task1 which is stored
in value property of the meta object(this is just an example) which does not initially exist but is created from within
task1. task2 can later have access to the value using <%= meta.value %> at a later time.
This way two tasks can share data..
There may be better ways of doing this, if you have come across please share

Sourcecode

//sample of a task created
module.exports = function(grunt){
    grunt.registerMultiTask('task1','', function(){
        var data = this.data,
            value = data.value;
        //process value
	grunt.config.set('meta.value', value); //sets a property called value on the grunt.config object
    });
}



//In the main gruntfile (grunt.js)
grunt.initConfig({
    pkg:'<json: package.json>',
    meta: {
        banner: '/*! <%= pkg.title || pkg.name %> - v<%= pkg.version %> - ' +
        '<%= grunt.template.today("yyyy-mm-dd") %>\n' +
        '<%= pkg.homepage ? "* " + pkg.homepage + "\n" : "" %>' +
        '* Copyright (c) <%= grunt.template.today("yyyy") %> <%= pkg.author.name %>;' +
        ' Licensed <%= _.pluck(pkg.licenses, "type").join(", ") %> */'
    },
    ...
    task1: {
        bar:{
            value: 'foo'
        }
    },
    task2:{
        barbar:{
            value: '<%= meta.value %>' //contains value passed from task1
        }
    }
    ...

    grunt.registerTask('default', 'task1:bar task2:barbar')

});
