grunt-fest

Compile Fest templates.

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:

npm install grunt-fest --save-dev

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

grunt.loadNpmTasks('grunt-fest');

The "fest" task

Overview

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

grunt.initConfig({
    fest: {
        options: {
            // Task-specific options go here.
        },
        target: {
            options: {
                // Target-specific options go here.
            }
        }
    }
})

Options

options.require

Type: String Default value: fest

Path to require Fest library.

options.compile

Type: Object Default value: undefined

Fest’s compile() options.

options.ext

Type: String Default value: .js

Compiled file’s extension.

options.name

Type: String Default value: undefined

Compiled function’s name. The basename of the source file will be used if is set to True.

options.template

Type: Function Default value: undefined

This function is called when template will be compiled. It takes an argument as an object with the following properties:

• src — path to the template
• relSrc — relative path to the template
• dest — path to the compiled file
• name — template’s name (relative to the source directory and w/o the extension)
• basename — template’s basename
• contents — compiled template

Usage Examples

Static mappings

grunt.initConfig({
    fest: {
        options: {
            compile: {
                beautify: true,
                debug: true
            }
        },

        // Compiles "fest/**/*.xml" to "fest/**/*.js"
        put_in_the_same_derictory: {
            src: 'fest/**/*.xml'
        },

        // Compiles "fest/**/*.xml" to "fest/**/*.xml.js"
        put_in_the_same_derictory_and_append_ext: {
            src: 'fest/**/*.xml',
            options: {
                ext: '.xml.js'
            }
        },

        // Compiles "test/**/*.xml" to "build/fest/**/*.js",
        'build': ['fest/**/*.xml'],

        // Compiles "test/qux.xml" to named function and writes it to "build/qux.js"
        v8: {
            src: 'fest/qux.xml',
            dest 'build/qux.js',
            options: {
                name: 'qux'
            }
        }
    }
})

Dynamic mappings

In this example Fest compiles "fest//*.xml" to "fest-build//*.js". See Building the files object dynamically documentation for more information.

grunt.initConfig({
    fest: {
        build: {
            files: [{
                expand: true,       // Enable dynamic expantion.
                cwd: 'fest',        // Src matches are relative to this path.
                src: ['**/*.xml'],  // Actual pattern(s) to match.
                dest: 'fest-build', // Destination path prefix.
                ext: '.js'          // Dest filepaths will have this extension.
            }],
            options: {
                compile: {
                    debug: false,
                    beautify: false
                }
            }
        }
    }
})

Template’s Usage

In this example Grunt builds AMD modules for the compiled templates.

grunt.initConfig({
    fest: {
        build: {
            files: [{
                expand: true,       // Enable dynamic expantion.
                cwd: 'fest',        // Src matches are relative to this path.
                src: ['**/*.xml'],  // Actual pattern(s) to match.
                dest: 'fest-build', // Destination path prefix.
                ext: '.js'          // Dest filepaths will have this extension.
            }],
            options: {
                template: function (data) {
                    // Make AMD module
                    return grunt.template.process(
                        'define(<%= JSON.stringify(name)  %>, function () { return <%= contents %> ; });',
                        {data: data}
                    );
                },
                compile: {
                    debug: false,
                    beautify: false
                }
            }
        }
    }
});

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt. Before pull-request to dev branch do rebase.
