I was inspired by Russ Cox's Regular Expression index article and by Sublime Text's "find anything" feature to build a code search web tool. Ås with most things this is an incomplete proof of concept more than anything.
- Install:
go get github.com/evanj/csearch - Run:
csearch (path to search)e.g.csearch $GOPATH/src
In the "Query" box, type a regexp and click search. The results are ugly, sorry.
In the "file name live" box, start typing. It will display a "live" list of results. This is both ugly and the results are not high quality.
I've forked codesearch into github.com/evanj/codesearch to be able to read the file names from the index file. This is a bit of overkill but it works. To get it, I've used govendor fetch github.com/google/codesearch/^::github.com/evanj/codesearch to set up the vendor path correctly. This means the fork maintains the original import paths for easy merging.
