Dolphin's codesearch UI

A server and associated JS app running (soon) on https://cs.dolphin-emu.org/

The application allows browsing through Dolphin's source code and browse through xrefs: what uses this function, where is this function defined, etc. A quick search feature allows regexp-matches over the whole codebase in a few milliseconds.

The xrefs indexing is powered by Google's Kythe project. The configuration for Dolphin's indexing pipeline is not part of this repository — see SADM instead for Buildbot and indexing scripts.

The regexp-search is powered by Google's codesearch Go library. The library is extended to index from Kythe LevelDB tables instead of using filesystem data.
