gtkaml is an XML parser that extends the Vala.Parser (literally) and transforms all your tags into a valid Gtk+ UI class described in the Vala language.

<VBox class:name="MyVBox" xmlns="Gtk" 
      xmlns:class="http://gtkaml.org/0.2">  
      <Label label="_Hello" with-mnemonic="true" 
             expand="false" fill="false" padding="0" />  
</VBox>

Features

• compact XML syntax for describing Gtk widgets
• code 'islands' (written in Vala) for signal handling and other methods/signals/properties/ in your widget class (so you don't modify the generated code ever)
• doesn't depend on an external library at run-time
• much more readable than the usual UI boilerplate (e.g. you don't need to worry about temporary variable names, or ever write hundreds of lines of code/markup)

To see a sample of what gtkaml looks like, see the example here. Have a look at the design goals for a quick specification + advancements in development.
