Getting Started

This plugin requires Grunt ~0.4.1

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-include-replace --save-dev

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

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

The "includereplace" task

Overview

The task allows you to preprocess your project file contents by replacing placeholder "variables" and including content from other files. In addition to "global" variables that are replaced in all files you specify, the task introduces the concept of "local" variables, which are passed as parameters to included files.

WARNING: The task does not check for recursive includes.

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

grunt.initConfig({
  includereplace: {
    your_target: {
      options: {
        // Task-specific options go here.
      }
      // Files to perform replacements and includes with
      src: '*.html',
      // Destination directory to copy files to
      dest: 'dist/'
    }
  }
})

Options

options.globals

Type: Object Default value: {}

Global variables availabe for replacement in all files.

options.prefix

Type: String Default value: @@

Variable/include directive prefix. Careful when changing as it is added to the regular expression used for finding variables to be replaced.

options.suffix

Type: String Default value: ``

Variable/include directive suffix. Careful when changing as it is added to the regular expression used for finding variables to be replaced.

options.includesDir

Type: String Default value: Relative to including file

Directory where includes will be resolved.

options.docroot

Type: String Default value: .

@@docroot is a magic local variable that contains the relative path from the file that uses it to the path specified.

Usage Examples

Default Options

includereplace: {
  dist: {
    options: {
      globals: {
        var1: 'one',
        var2: 'two',
        var3: 'three'
      },
    },
    src: '*.html',
    dest: 'dist/'
  }
}
Files array format
includereplace: {
  dist: {
    options: {
      globals: {
        var1: 'one',
        var2: 'two',
        var3: 'three'
      },
    },
    files: [
      {src: 'js/**/*.js', dest: 'dist/', expand: true, cwd: 'src/'},
      {src: '*.css', dest: 'dist/css/', expand: true, cwd: 'src/css'}
    ]
  }
}
Files object format
includereplace: {
  dist: {
    options: {
      globals: {
        var1: 'one',
        var2: 'two',
        var3: 'three'
      },
    },
    files: {
      'dist/js/': ['**/*.js', '!dist/**/*.js'],
      'dist/css/': ['**/*.css', '!dist/**/*.css']
    }
  }
}

Custom Options

The following example allows include statements to appear as comments in HTML files by altering the prefix and suffix. Also all includes are resolved relative to the directory inc/ (relative to your Gruntfile) rather than relative to including file.

includereplace: {
  dist: {
    options: {
      prefix: '<!-- @@',
      suffix: ' -->',
      includesDir: 'inc/'
    },
    src: '*.html',
    dest: 'dist/'
  }
}

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.
