Search code on GitHub with better semantics — from the command-line.
Ultimately, I want grep-like semantics to explore across hundreds of projects. It should be fluid, iterative, and maybe even impress my co-workers.
Codesearch is simple: cs [term]. It shows you the information you need
without much more. There are two output modes: the default is similar to
ripgrep and -G gets you grep.
On top of that, we use the ANSI Hyperlink Sequence to make everything clickable. Line numbers take you directly to the file with it highlighted and file names to the file. We're not quite sure where repository names take you yet but you can find out!
go install github.com/coxley/codesearch/cs@latest
# or with a version like...
# go install github.com/coxley/codesearch/cs@v1.0.3
There were a handful of tools I was spoiled by when I worked at Facebook.
BigGrep was one of them.
cs is modeled after it's experience. It wraps
around GitHub's REST and GraphQL APIs. One to get a collection of ranked
results, the other to get file contents for stuff like --context, --before,
and --after.
Just enough color is used to find what you need without being over-bearing. We're not trying to boil the ocean. We just want to find things.
Listen, I'm barely navigating the sea of SaaS as it is. My company doesn't have it and this only cost booze and a weekend.
In all seriousness, I've heard rad things about Sourcegraph. There might even
be opportunity to support it as an alternative backend in cs. But you should
be able to enjoy comfortabl search without it.
Setup:
You should get a setup prompt the first time you run cs. If you get bored and
miss it, just delete ~/.codesearch.yaml and go at it again.
Note: If you're using GitHub Enterprise, the Base URL will be
https://[domain]/. We'll take care of adding the api-specific details.
> ./cs viper.WriteConfig
Welcome to codesearch!

Base URL [https://api.github.com/]:
You'll need a GitHub personal token for this to work. Head
on over to create one: https://github.com/settings/tokens/new?description=Codesearch&scopes=repo%2Cread%3Auser%2Cread%3Aorg
Set any expiry you want - it stays on your machine. Just make sure to give it
'repo' scope at minimum. The other two are supplementary but make everything
smooth.

Awesome! You can run ./cs set-org if you'd like
to scope searches to a specific organization.
Set a default org:
While cs works for anything on Github, it's best use-case is within a company
/ team / whatever-structure hosting their projects here. That... and you're
likely to find the results you want before being rate-limited this way.
It's easy to change on the fly so don't feel committed.
# cs set-org [name] works too

Searching:
Your first search - exciting! If you're using a modern terminal, try clicking on the line numbers, filenames, and repositories.

# While GitHub requires "owner/repo" for the repo filter, we fix that for you
# if org is set. (regardless of config or --org)

Sometimes you want the URLs in your face. Use --url-prefix/-u for those occassions.

Context:
Like grep, ripgrep, and similar, cs supports contextual line flags. Leading, trailing,
and surrounding, oh my!

Sometimes you only want the repos that match. These are clickable too!
