grunt-concat-include

Concatenate files using an include file.

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-concat-include --save-dev

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

grunt.loadNpmTasks('grunt-concat-include');

Concat task

Run this task with the grunt concatinclude command.

Task targets, files and options may be specified according to the Grunt Configuring tasks guide.

Options

separator

Type: String Default: grunt.util.linefeed

Concatenated files will be joined on this string. If you're post-processing concatenated JavaScript files with a minifier, you may need to use a semicolon ';' as the separator.

banner

Type: String Default: empty string

This string will be prepended to the beginning of the concatenated output. It is processed using [grunt.template.process][], using the default options.

(Default processing options are explained in the [grunt.template.process][] documentation)

footer

Type: String Default: empty string

This string will be appended to the end of the concatenated output. It is processed using [grunt.template.process][], using the default options.

(Default processing options are explained in the [grunt.template.process][] documentation)

Usage Examples

Concatenating with a custom separator

In this example, running grunt concatinclude:dist (or grunt concatinclude because concatinclude is a [multi task][multitask]) will concatenate the files listed in the include.inc file, joining files with ; and writing the output to dist/built.js.

// Project configuration.
grunt.initConfig({
  concatinclude: {
    options: {
      separator: ';',
    },
    dist: {
      files: {
      	'dist/built.js': ['src/include.inc']
      }
    }
  }
});

Banner comments

In this example, running grunt concatinclude:dist will concatenate the files listed in the include.inc file, placing a banner comment at the top, and writing the output to dist/built.js.

This generated banner will be the contents of the banner template string interpolated with the config object. In this case, those properties are the values imported from the package.json file (which are available via the pkg config property) plus today's date.

Note: you don't have to use an external JSON file. It's also valid to create the pkg object inline in the config. That being said, if you already have a JSON file, you might as well reference it.

// Project configuration.
grunt.initConfig({
  pkg: grunt.file.readJSON('package.json'),
  concatinclude: {
    options: {
      banner: '/*! <%= pkg.name %> - v<%= pkg.version %> - <%= grunt.template.today("yyyy-mm-dd") %> */'
    },
    dist: {
      files: {
      	'dist/built.js': ['src/include.inc']
      }
    }
  }
});

Footer comments

In this example, running grunt concatinclude:dist will concatenate the files listed in the include.inc file, placing a footer comment at the bottom, and writing the output to dist/built.js.

This generated footer will be the contents of the footer template string interpolated with the config object. In this case, those properties are the values imported from the package.json file (which are available via the pkg config property) plus today's date.

Note: you don't have to use an external JSON file. It's also valid to create the pkg object inline in the config. That being said, if you already have a JSON file, you might as well reference it.

// Project configuration.
grunt.initConfig({
  pkg: grunt.file.readJSON('package.json'),
  concatinclude: {
    options: {
      footer: '/*! <%= pkg.name %> - v<%= pkg.version %> - <%= grunt.template.today("yyyy-mm-dd") %> */'
    },
    dist: {
      files: {
      	'dist/built.js': ['src/include.inc']
      }
    }
  }
});

include.inc file

The grun concatinclude task will look for files to concatenate together from a include.inc file.

The task will include all files with an @require directive, and will ignore all other lines.

Include files directly: @require external/example.js

Include all files of a type: @require external/*.js

Include all files in a directory: @require external/*

Include all files in a directory and all sub-directories: @require external/**

-- jQuery files			 // this line will be ignored

	@require external/jquery/jquery.js
	@require external/jquery/jquery.plugin1.js
	@require external/jquery/jquery.plugin2.js
	@require external/jquery/jquery.plugin3.js

-- External files		 // this line will be ignored

	@require external/external/*.js

-- Project files		 // this line will be ignored

	@require app/objects/**
	@require app/helpers/**
	@require app/models/**
	@require app/routes/**
	@require app/views/**
