Custom variables

{{ var $size-1: "small" }}
{{ var $size-2: "medium" }}
{{ var $size-3: "large" }}

<p>My cat is $size-1.</p>
<p>My dog is $size-2.</p>
<p>My horse is $size-3.</p>
<p>But all of them have things that are $size-1, $size-2 and $size-3 in relation to their own size.</p>

{{ include('inc.html', {"biggest": "$size-3"}) }}

inc.html

<hr />
<p>But which is the biggest size? {{ biggest }}</p>

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-more --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-more');

The "includereplacemore" 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 includereplacemore to the data object passed into grunt.initConfig().

grunt.initConfig({
  includereplacemore: {
    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.

Must be at least 1 character, otherwise resets to default value.

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.

Must be at least 1 character, otherwise resets to default value.

options.startIf

Type: String Default value: if

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

Must be at least 1 character, otherwise resets to default value.

options.endIf

Type: String Default value: endif

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

Must be at least 1 character, otherwise resets to default value.

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.

options.processIncludeContents

Type: Function Default value: undefined

A function called for every included file prior to processing by grunt-include-replace. It is passed the include file contents and local variables as parameters and should return the (possibly altered) file contents.

Usage Examples

Default Options

includereplacemore: {
  dist: {
    options: {
      globals: {
        var1: 'one',
        var2: 'two',
        var3: 'three'
      },
    },
    src: '*.html',
    dest: 'dist/'
  }
}

Files array format

includereplacemore: {
  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

includereplacemore: {
  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. The prefix and suffix for conditional IF blocks is also changed. Also all includes are resolved relative to the directory inc/ (relative to your Gruntfile) rather than relative to including file.

includereplacemore: {
  dist: {
    options: {
      prefix: '<!-- {{',
      suffix: ' -->',
      startIf: ' _if_ ',
      endIf: ' _endif_ ',
      includesDir: 'inc/'
    },
    src: '*.html',
    dest: 'dist/'
  }
}
