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

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 …
