Looks very similar to Mozilla's DXR: https://wiki.mozilla.org/DXR

(DXR also uses Clang as its parsing engine)

DXR needs Python/CGI to run :-) My favorite difference between the Woboq Code Browser and DXR is to have a pure static website generated ahead of time without requiring dynamic code or a database on the HTTP server.

Well, thanks for the downvote. I'm administering the server code.woboq.org is running on, so I think I have reasons to like that static HTML fact ;)

Sometimes a single downvote is just someone mis-tapping while scrolling on a touchscreen. At any rate, your post is not gray right now.

Which they mention right there in the second paragraph.

Very nice, I've been looking for something like this for my own open source project, have even been thinking about developing one myself (also using clang/llvm, to get metrics for visualization, call graphs, usages, data dependencies etc).

Current similar systems, as far as I know, are either very limited, or slow, or almost impossible to get to work for other projects than what they're based on.

Nice work. I hope the system itself will also be open source some day :)

DXR is similar, and is open source: https://github.com/mozilla/dxr/tree/testing

I saw DXR when I was searching around, but did not know of the github, and that it is still actively maintained. Thanks!

I have built a similar one for Github hosted .Net projects http://sourcecodereader.apphb.com , detailed description is provided on my blog http://rajeeshcv.com/post/details/47/introducing-sourcecoder...

The PHP project uses OpenGrok for its codebase (although curiously at an address suggesting it uses LXR instead). http://lxr.php.net/ is always the go-to place to read the soure code now, not the Git repo. It's especially useful when tearing through the Zend engine.

Is there an open-source equivalent of this anywhere? I have seen DXR/LXR but I think they use an "approximate" parser. So it will get confused by functions in different scopes with the same name, and so forth.

This actually uses clang which can do the analysis exactly.

I was pleasantly surprised to see that DXR uses clang too, these days: https://github.com/mozilla/dxr/tree/testing/plugins/clang

Anyone with time willing to setup this or lxr or dxr for the webkit project would get eternal gratitude from me.

Very nice! Suggestion : It would be great to also have a monospace font in the tooltip view.

Btw this would be almost impossible with dynamic languages.
