Source code has moved to github.com:

• For gtkaml-0.6 beta check out https://github.com/radare/gtkaml3
• For gtkaml-0.4 legacy check out https://github.com/radare/gtkaml

Gtkaml is a markup language based on Vala which lets you create Gtk+ composite widgets through concise XML:

<HBox homogeneous="false">  
      <Label label="_Hello" with-mnemonic="true" expand="false" fill="false"/>  
      <Entry g:public="my_entry" text="World! "/>
</HBox>

or by using Gtkon object notation:

HBox !homogeneous {
  Label with-mnemonic label="_Hello" !expand !fill;
  Entry $my_entry text="World!";
}

Features

• compact XML syntax for describing Gtk widgets
• JSON-like and less verbose Gtkon syntax
• 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)
• you don't depend on gtkaml 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)
• works with any library that has a .vapi file, not just Gtk+ (composition methods can be specified in the .implicits file)

To see a sample of what gtkaml looks like, see the examples here. Have a look at the design goals for a quick specification + advancements in development. A reference of the gtkaml keywords is made available too. Examples can be found in /tests and /examples in the source distribution.

You can discuss about gtkaml on the gtkaml-dev mailing list or you can .

(2013-01-03) gtkaml 0.6 beta 3

This third beta release contains the following fixes compared to beta2:

• prevent a crasher when class name is blank
• stop stripping CDATA tags' leading and trailing whitespaces
• honor -D defines in the context used to parse members
• honoring -d for .gtkaml generated files
• fix a bug copying fields twice if generated automatically by properties

Support was added for enum literals, like <Window type='toplevel' />

There should be no notable differences compared to 0.4.3's functionality other than:

• compatibility with Vala 0.18
• source files' order from command line is not relevant anymore (previous architectural limitation)
• support for custom creation methods (the construct will still be generated by gtkaml)
• support for enum literals
• '.implicits' files renamed to '.markuphints'

Source is available in the svn branch gtkaml-0.6 for now.

(2011-03-22) gtkaml 0.4.3

• #! shebang support for GtkON files to be used with the gtkaml executable
• vim syntax files for gtkon and gtkaml files. (thanks [email protected]). See editors/vim/README on how to use them.
• removed own debian/* files in favour of debian's own packaging scripts (thanks David [email protected])
• optional running of tests with --enable-tests at configure stage

See the release notes.
