Migrate Jekyll (gh-pages) themes to use handlebars instead of liquid.

Follow this project's author, Jon Schlinkert, for updates on this project and others.

Install

Install with npm:

$ npm install --save hekyll

Usage

Quickstart

The easiest way to use hekyll is to call the static .build method with an options object.

Required options

At minimum, you will need to define the following:

• options.cwd - the source directory with the jekyll theme to convert
• options.destBase - the base destination directory to write the converted or copied files to.

Example

var Hekyll = require('hekyll');

Hekyll.build({cwd: 'jekyll_theme_folder', destBase: 'output_folder'})
  .then(function() {
    console.log('converted!');
  })
  .catch(console.error);

Custom

The main export is a constructor function that takes an options object. Once an instance is created, you can use hekyll's methods to convert and copy files however you want. See the API documentation for more details.

Example

var Hekyll = require('hekyll');
var hekyll = new Hekyll({
  cwd: 'jekyll_theme_folder',
  destBase: 'output_folder'
});

function dest(dir) {
  return function(file) {
    return dir || '';
  };
}

hekyll.templates([
  `{,_*/**/}*.{html,markdown,mdown,mkdown,mkdn,mkd,md,textile,liquid}`,
  '!**/{README*,LICENSE*,CONTRIBUTING*}'
], dest())
  .then(hekyll.assets('{assets,public}/**', dest()))
  .then(hekyll.copy('_config.yml', dest()))
  .then(hekyll.copy('_data/**', dest('_data')))
  .then(hekyll.copy('_sass/**', dest('_sass')))
  .then(hekyll.copy('styles.scss', {addImport: 'custom'}, dest('_sass')))
  .then(hekyll.copy('**/*.{xml,txt}', function(file) {
    file.extname += '.hbs';
    return '';
  }))
  .then(hekyll.text(dest()))
  .then(function() {
    console.log('done!');
  })
  .catch(console.error)

Required Options

• cwd: the directory with source files for a Jekyll theme.
• destBase: the base destination directory for the converted theme.

API

Hekyll

Create an instance of Hekyll with the given options.

Params

• options {Object}

Example

var Hekyll = require('hekyll');
var hekyll = new Hekyll();

.templates

Copies and converts liquid templates to handlebars templates using the given glob patterns, options and dest function.

Params

• patterns {String|Array}
• options {Object}
• dest {Function}: Must return a string.
• returns {Promise}

Example

hekyll.templates(patterns, {destBase: 'foo'}, function(file) {
  // optionally do stuff to vinyl "file" object
  // the returned folder is joined to `options.destBase`
  return 'folder_name';
});

.copy

Copies files using the given glob patterns, options and dest function. Converts liquid templates and strips front matter from files.

Params

• patterns {String|Array}
• options {Object}
• dest {Function}: Must return a string.
• returns {Promise}

Example

hekyll.copy(patterns, {destBase: 'foo'}, function(file) {
  return '';
});

.assets

Copies assets files using the given glob patterns, options and dest function. Does not read the files or modify file contents in any way.

Params

• patterns {String|Array}
• options {Object}
• dest {Function}: Must return a string.
• returns {Promise}

Example

hekyll.assets(patterns, {destBase: 'foo'}, function(file) {
  return '';
});

.text

Copies plain text files using the given glob patterns, options and dest function. Strips front-matter, but does not attempt to convert templates.

Params

• patterns {String|Array}
• options {Object}
• dest {Function}: Must return a string.
• returns {Promise}

Example

hekyll.text(patterns, {destBase: 'foo'}, function(file) {
  return '';
});

Choosing a theme

~20 jekyll themes were tested during the creation of this library, including all of the poole/poole themes from @mdo, and all of the built-in gh-pages themes. Most themes convert flawlessly, but some have nuances that might require some manual editing.

Handlebars helpers

To be able to render the migrated templates with handlebars, you will first need to include any missing handlebars helpers that were converted from liquid filters and tags during the migration.

Here are some libraries that might be useful for this:

• template-helpers - generic helpers that can be used with any template engine.
• handlebars-helpers - more than 150 handlebars helpers

Bug reports

If you find a bug or something that doesn't convert correctly, please let me know, I want this to work as seamlessly as possible.
