Note: the Liferay theme generator is still in development and is not guaranteed to work on all platforms/environments.

Liferay theme generator allows you to generate new themes to be used with Liferay Portal, and supplies you with the necessary tools to deploy and make quick modifications to your theme.

1. Install Node.JS, if you don't have it yet.
   Note: the Liferay theme generator requires Node version 0.10.x or 0.12.x, due to issues with node-sass the generator will not currently work with Node 0.11.x.
2. run <sudo> npm install -g yo gulp to install global dependencies.

1. Install generator: <sudo> npm install -g generator-liferay-theme
2. Run yo liferay-theme to start theme generator and follow prompts to name and configure your theme.

Note: the generator will create a new folder in your current directory that will house your theme.

Unfortunately, there can be some minor headaches when using the generator on Windows. The main reason is because, by default, we use node-sass, which requires node-gyp to run. node-gyp requires Python and Visual Studio to be installed. You can read more at the following links:
node-gyp Installation
Visual Studio Setup

There is one other possible alternative that some may find easier to setup. You can use the ruby based version of Sass. In order to use that version of Sass, you'll need to install Ruby with the Ruby Installer, and install the Sass and Compass gems from the command line (gem install sass compass), and when the generator asks you if you need Compass support, type "Y". This will bypass node-gyp completely, and use the Ruby versions of Sass and Compass.

Available generators:

• liferay-theme
• liferay-theme:import
• liferay-theme:themelet

yo liferay-theme

The default liferay-theme generator creates a new theme that inherits styles from liferay-theme-styled or liferay-theme-unstyled.

yo liferay-theme:import

The liferay-theme:import generator enables you to import pre-existing Liferay themes from the SDK.

yo liferay-theme:themelet

The liferay-theme:themelet generator enables you to create theme fragments called themelets.

The advantage of themelets is that reused code/components that often exist in multiple themes can be abstracted and easily reused in all of your themes.

Once the generator is done creating your theme, there are multiple gulp tasks available to expedite theme development. See liferay-theme-tasks for more detail.
