Version management

This project use semantic versionning to define the releases. This mean that each stable release of the project will get associate a version number of the form vX.Y.Z.

  • X define the major version number
  • Y define the minor version number
  • Z define the patch version number

When a release contains only bug fixes, the patch number increase. When the release contains new features backward compatibles, the minor version increase. When the release contains breaking changes, the major version increase.

Thus, it should be safe to depend on a fixed major version and moving minor version of this project.

Install MDL Seaside

To install MaterialDesignLite on your Pharo image you can just execute the following script: Spotter Cloud Workspace Url. See ZnWorkspace section for installing a ZnWorkspace if you so want.

    Metacello new
    	githubUser: 'DuneSt' project: 'MaterialDesignLite' commitish: 'master' path: 'src';
    	baseline: 'MaterialDesignLite';

To add MaterialDesignLite Seaside to your baseline just add this:

    	baseline: 'MaterialDesignLite'
    	with: [ spec repository: 'github://DuneSt/MaterialDesignLite:master/src' ]

Note that you can replace the #master by another branch as #development or a tag as #v1.0.0, #v1.? or #v1.2.? .

Getting started

We use as a base the files product by Google's Material Design Lite. To have a working Material Design Seaside application we need to add those files. Most of them can be easily added via a file library but one file need to be explicitely added because this file change depending on the colors you wish for your application.

For now MDL Seaside is based on version 1.3.0 of Google's Material Design Lite.

Add the right libraries and file

To use MaterialDesign you will need to add JQuery and Material Design library to your application:

	(WAAdmin register: self asApplicationAt: 'myApplication')
		addLibrary: JQDeploymentLibrary;
		addLibrary: MDLLibrary

Then you will need to add the css file with the colors. To do so, you will have two options:

  • Add it to your file library
  • Add it in your #updateRoot:

You can find the files on

They are in the form of:


  • XXX = primary color
  • YYY = accent color

Add the css file in the updateRoot of your application:

    MyApplication>>updateRoot: anHtmlRoot
	    super updateRoot: anHtmlRoot.
	    anHtmlRoot beHtml5.
	    anHtmlRoot stylesheet url: (WAUrl absolute: '').

Subclassing MDLApplication

Another simple way to start with MDL is to subclass MDLApplication to create your root component. MDLApplication is a class to help you to start an application easily. It will keep in a FileLibrary most of MDL's files.

Since MaterialDesignLite works with a primary color and an accent color you will need to set them. To do so you will need to add this to your #initialize method:

    self primaryColor: MDLColor indigo secondaryColor: MDLColor pink

You can find the possible colors into the class MDLColor class.


You can find multiple examples when the application will be installed at the url: http://localhost:8080/MDLDemo

When you install in a plain Pharo image you need to start the seaside server first by opening World menu > Tools > Seaside Control Panel and adding and starting an appropropriate ZnZincServerAdaptor. If you do not use port 8080, change the port in the URL.

You can find a demo at:


If you look at a cloud workspace page, you'll see it mentions a ZnWorkspace. This is how you can load it up.

Gofer it
  squeaksource: 'ZincHTTPComponents';
  package: 'Zinc-WWS-Client';

To open one, just do a

ZnWorkspace openUrl: ''
