ANTLR grammar for XKB, and Relax NG schema (draft)

I completed the ANTLRv3 grammar for symbols/ configuration files of XKB. The grammar can parse and create the abstract syntax tree (AST) for all keyboard layouts in xkeyboard-config. ANTLRv3 helps you create parsers for domain specific languages (DSL), an example of which is the configuration files in XKB. Having the ANTLRv3 grammar for a configuration …

Looking into the symbol files

In the previous post, we talked about the ANTLR grammar that parses the XKB layout files. The grammar is available at http://code.google.com/p/keyboardlayouteditor/source/browse.

Testing the updated IM support in GTK+

In Improving input method support in GTK+-based apps, we talked about some work to update the list of compose sequences that GTK+ knows to the latest version that comes from Xorg. From 691 compose sequences, we now support over 5000. The patch has landed in GTK+ (trunk), and here are instructions for testing. If you …
