codesearch

There's also https://github.com/google/codesearch for local only search

What is a good open-source system for code search if I want to plug 100 or so git repos into it and have it available over the web? GH search is not desirable because it would search too broadly and would not cover repos on Gitlab etc. I looked at the Debian code search [1] in the past, but for some reason thought it required a bit too much effort and didn't complete my investigation of it. Though [2] looks pretty approachable. Sourcegraph mentioned Zoekt [3], but I am not sure how usable it is. If it was pretty good, why did Sourcegraph OSS exist? Finally, from all the discussion how Sourcegraph OSS was very behind in the past few years, I guess there is no serious plan to fork it? Edit: GCS release [4] seems to have been open-sourced without a frontend. Edit2: Livegrep [5] and Opengrok [6] were recommended higher in the thread. Quite ex

Whenever I work on huge codebase (think 1M+ lines of code), I always reach for Russ Cox's codesearch https://github.com/google/codesearch. It requires indexing the codebase first, which takes 15 minutes or so, but after that searches are instant.

There is some older version that's open source, I haven't tried it and I don't know how much of today's code search is based on it. https://github.com/google/codesearch

csearch/cindex has not changed for 5 years, pretty useful and reliable https://github.com/google/codesearch cscope: last version in 2012, combined with Vim http://cscope.sourceforge.net/ [edit] actually codesearch received 2 fixes in 2018

I found this on github in Google's org : https://github.com/google/codesearch

Maybe that was 2018, but last tool I adopted is 8 years old cindex/csearch code (well text) indexer: https://github.com/google/codesearch

You can store a local search index of your code using https://github.com/google/codesearch, which uses this algorithm in the background.

The project was released by the original author here. https://github.com/google/codesearch There is no information on the subject besides the 3 blog posts and the proof of concept.

If this looks cool you might also be into Google Code Search https://github.com/google/codesearch

(Sorry, this is mildly off-topic.) Not sure if this fits your usecase, but you should check out codesearch if you haven't already: https://github.com/google/codesearch (Russ Cox's excellent writeup is here: https://swtch.com/~rsc/regexp/regexp4.html)

Unfortunately, this doesn't support regular expressions, which is a very useful feature for a code search engine. See https://github.com/google/codesearch for one implementation of this.

I have written about it all here (I maintain searchcode.com ) http://www.boyter.org/category/searchcode/ specifically http://www.boyter.org/2013/02/why-code-search-is-difficult/ is of note. If you want to see implementations I suggest looking at https://github.com/OpenGrok/OpenGrok https://github.com/ggreer/the_silver_searcher https://github.com/google/codesearch and my own https://github.com/boyter/searchcode-server

I've recently ran into debian code search again, https://codesearch.debian.net/. Built on top of Russ Cox's Code search (https://github.com/google/codesearch), and quite well documented. Can't say I've used it much, but it gives a few pointers into how you could build a better one yourself.

It's like codesearch [1]. [1] https://github.com/google/codesearch
