Welcome to lxr.linux.no -- the Linux Cross Reference
Welcome to lxr.linux.no LXR (formerly "the Linux Cross Referencer") is a software toolset for indexing and presenting source code repositories. LXR was initially targeted at the Linux source code, but has proved usable for a wide range of software projects. lxr.linux.no is currently running an experimental fork of the LXR software. Browse the code These are the browsable source code repositores at lxr.linux.no:

LXR Source code For the interested, the source code is available as a git repository at https://github.com/argggh/lxrng. Not all of the functionality present in mainline LXR is available in this version, and the documentation is unfortunately rather sparse. Don't hesitate to contact lxr@linux.no with any questions, though. Thanks Perl, CPAN, PostgreSQL, Xapian and Excuberant Ctags are invaluable components of the lxr.linux.no infrastructure. About lxr.linux.no is provided as a non-profit service to the public in the hope that it is found useful. It is herded by Arne Georg Gisnås Gleditsch in his spare time.
Disclaimer This site and the software running on it has seen very sparse development over at last decade(s), and many source code visualization options now exist that surpass this site in terms of functionality and capabilities. lxr.linux.no is kept online as a sort of time capsule at this point, to service existing links on the internet and users who may still be actively using it.
