git-find-rs

A CLI tool used for finding git repositories.

I've been using git-find-repos every day for a long time, so it seemed like a good idea to Rewrite it in Rust to learn the language.

Note that as of right now, this is mostly for my own understanding and built for my own use case.

Benchmarks

Obviously this is not a totally fair comparison as Rust is compiled, but compared to git-find-repos we see the following improvement on my 2017 MacBook Pro with ~100 git directories:

$ hyperfine --warmup 3 '/usr/local/bin/git-find-rs $HOME/code' '$HOME/.local/bin/git-find-repos $HOME/code'
Benchmark 1: /usr/local/bin/git-find-rs $HOME/code
  Time (mean ± σ):     284.2 ms ±   6.8 ms    [User: 45.5 ms, System: 234.2 ms]
  Range (min … max):   274.1 ms … 297.4 ms    10 runs

Benchmark 2: $HOME/.local/bin/git-find-repos $HOME/code
  Time (mean ± σ):     761.3 ms ±  37.6 ms    [User: 203.5 ms, System: 542.5 ms]
  Range (min … max):   733.6 ms … 860.2 ms    10 runs

Summary
  '/usr/local/bin/git-find-rs $HOME/code' ran
    2.68 ± 0.15 times faster than '$HOME/.local/bin/git-find-repos $HOME/code'

Installation

# Clone this repo to a local directory, for example `/Users/foo/git-find-rs`
$ cargo build --release
$ ln -s /Users/foo/git-find-rs/target/release/git-find-rs /usr/local/bin/git-find-rs

---

Using in fish shell

Create a function to use git-find-rs, for example:

function repo
    set initial_query $argv
    set code_dir "/Users/foo/code"
    set dest (git-find-rs "$code_dir" | fzy -q "$initial_query" -l 20) && cd "$dest"
end

You can then:

$ repo my-repo-name

This will show a list of git directories. You can type a partial string of the repo name and fzy will match this for you. Selecting a directory will cd into the directory.
