Getting Started

This plugin requires Grunt ~0.4.2

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-figlet --save-dev

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

grunt.loadNpmTasks('grunt-figlet');

The "figlet" task

Overview

In your project's Gruntfile, add a section named figlet to the data object passed into grunt.initConfig(). This will create a "figlet" variable that you can use in banner templates.

grunt.initConfig({
    figlet: {
        // These will be the default options for the targets
        options: {
            font: 'Dancing Font',
            horizontalLayout: 'default',
            verticalLayout: 'default'
        },
        banner1: 'Some Text',
        banner2: 'More Text',
        
        /*
            More advanced options let you customize the text and create a comment block
            for the ASCII Art
        */

        banner3: {
            options: {
                text: 'Code Comment',
                font: 'Graffiti',
                comment: {
                    style: 'js',
                    generate: function(asciiArtText) {
                        return asciiArtText + '\nThis is a test message.'
                            + '\nMore random text\nAnd some more...';
                    }
                }
            }
        }
    },

    // ...

    // The figlet task will create a "figlet" config variable with properties holding
    // the results that corespond to the targets. You can use these variables to print 
    // out the banners. See the example below.

    uglify:{
        options: {
            banner: '<%= figlet.banner3 %>\n'
        },
        sample: {
            src: 'some-file.js',
            dest: 'some-file.min.js'
        }
    },
});

Options

This task primary delegates to FIGlet.js, though it takes in some additional options.

options.text

Type: String Default value: ''

A string value that is converted into ASCII Art.

options.font

Type: String Default value: 'Standard'

A string value that indicates the FIGlet font to use.

options.horizontalLayout

Type: String Default value: 'default'

A string value that indicates the horizontal layout to use. FIGlet fonts have 5 possible values for this: "default", full", "fitted", "controlled smushing", and "universal smushing". "default" does the kerning the way the font designer intended, "full" uses full letter spacing, "fitted" moves the letters together until they almost touch, and "controlled smushing" and "universal smushing" are common FIGlet kerning setups.

options.verticalLayout

Type: String Default value: 'default'

A string value that indicates the vertical layout to use. FIGlet fonts have 5 possible values for this: "default", full", "fitted", "controlled smushing", and "universal smushing". "default" does the kerning the way the font designer intended, "full" uses full letter spacing, "fitted" moves the letters together until they almost touch, and "controlled smushing" and "universal smushing" are common FIGlet kerning setups.

options.comment

Type: Object Default value: undefined

If present, then a comment block will be constructed (see examples down below).

options.comment.style

Type: String or Function Default value: 'js'

Indicates the style of the comment. Right now only "js" is supported. If you want to create a custom comment style, you can make this equal to a function that takes in the final comment block text. This function should return the final comment block.

options.comment.generate

Type: Function Default value: A function that returns the generated ASCII Art text.

Indicates how to construct the comment block text. This should equal a function that takes in the ASCII Art text and returns the final comment message. You can use this if you want to add additional text on top of the generated ASCII Art.

Usage Examples

Default Options

Below is a simple example that uses the default options.

grunt.initConfig({
    figlet: {
        banner1: 'Some Text'
    },

    // ...

    // The figlet task will create a "figlet" config variable with properties holding
    // the results that corespond to the targets. You can use these variables to print 
    // out the banners. See the example below.

    uglify:{
        options: {
            banner: '/*\n<%= figlet.banner1 %>\n*/\n'
        },
        sample: {
            src: 'some-file.js',
            dest: 'some-file.min.js'
        }
    },
});

Custom Options

Below is an example that uses custom options.

grunt.initConfig({
    figlet: {
        banner1: {
            options: {
                text: 'Code Comment',
                font: 'Graffiti',
                comment: {
                    style: 'js',
                    generate: function(asciiArtText) {
                        return asciiArtText + '\nThis is a test message.'
                            +'\nMore random text\nAnd some more...';
                    }
                }
            }
        }
    },

    // ...

    // The figlet task will create a "figlet" config variable with properties holding
    // the results that corespond to the targets. You can use these variables to print 
    // out the banners. See the example below.

    uglify:{
        options: {
            banner: '/*\n<%= figlet.banner1 %>\n*/\n'
        },
        sample: {
            src: 'some-file.js',
            dest: 'some-file.min.js'
        }
    },
});
