This is a Google Desktop Indexing plugin for Pidgin. It registers IM events directly when generated (without log parsing) and it's written in C

A related project is PidginGDS by gatorstudent20.

The plugin doesn't work on Linux (no GDS SDK available yet or maybe never) but a workaround is here: "Trick to Make Google Desktop Search Index Pidgin Conversation Log". You could too use Tracker or Beagle instead.
