Quick, simple zsh plugin manager

zrat

zr 1.0.2
by Jonathan Dahan <hi@jonathan.is>

zr [[http://example.com]plugin/name[.git/path/to/file.zsh]]    fetch plugins and output sourceable zsh
zr --update                                                    updates plugins from already sourced zsh
zr help                                                        show help

install

zr is published to crates.io, and can be installed with cargo install zr

usage

Add this to your ~/.zshrc:

# simplest usage
. <(zr frmendes/geometry junegunn/fzf.git/shell/key-bindings.zsh)

A bit more complex example, that only generates when .zshrc has been updated:

# Generate new ~/.config/zr.zsh if it does not exist or if ~/.zshrc has been changed
if [[ ! -f ~/.config/zr.zsh ]] || [[ ~/.zshrc -nt ~/.config/zr.zsh ]]; then
  zr \
    frmendes/geometry \
    jedahan/geometry-hydrate \
    junegunn/fzf.git/shell/key-bindings.zsh \
    > ~/.config/zr.zsh
fi

source ~/.config/zr.zsh

identifiers

zr supports four identifier formats. The last format requires .git as a delimeter.

format resolves to
author/name *.zsh from https://github.com/author/name
author/name/file.zsh file.zsh from https://github.com/author/name
https://gitlab.com/a/plugin *.zsh from https://gitlab.com/a/plugin
https://gitlab.com/a/plugin.git/file.zsh file.zsh from https://gitlab.com/a/plugin.git. The .git is used as a delimeter, and is required.

speed

The following two benchmarks show on my dell xps13 9380

  • it takes 5ms to generate a sourceable script from a dozen or so repos
  • it takes an additional 15ms for zsh to load said script
# install hyperfine for benchmarking
$ which hyperfine || cargo install hyperfine

# run 
$ hyperfine --warmup 3 'zsh -d -f -l -c "source benchmark.zsh && zrinit && exit"' 'zsh -d -f -l -c "source benchmark.zsh && . <(zrinit) && exit"'

Benchmark #1: zsh -d -f -l -c "source benchmark.zsh && zrinit && exit"
  Time (mean ± σ):       5.3 ms ±   2.3 ms    [User: 2.8 ms, System: 2.4 ms]
  Range (min … max):     2.9 ms …   9.9 ms    285 runs

Benchmark #2: zsh -d -f -l -c "source benchmark.zsh && . <(zrinit) && exit"
  Time (mean ± σ):      21.8 ms ±   1.0 ms    [User: 17.5 ms, System: 5.1 ms]
  Range (min … max):    19.7 ms …  26.4 ms    127 runs
