rg

rg

recursively searches directories for a regex pattern while respecting your gitignore

curl -fsSL https://unflab.app/get | sh -s -- rg

Installs to ~/.local/bin. Add --prefix /usr/local/bin to
put it somewhere else, or --uninstall to remove it.

Why it’s here

No dependency problem to solve — it’s here so it installs the same way as everything else.

Details

Built from that exact tarball, with its SHA-256 pinned in the
recipe. The binary links against nothing outside /usr/lib
and /System/, checked in CI before release.

ripgrep (rg) is a line-oriented search tool that recursively searches the
current directory for a regex pattern. By default, ripgrep will respect gitignore
rules and automatically skip hidden files/directories and binary files. (To
disable all automatic filtering by default, use rg -uuu.) ripgrep has first
class support on Windows, macOS and Linux, with binary downloads available for
every release. ripgrep is similar to other popular search tools like The Silver
Searcher, ack and grep.

man rg is the full reference; rg --help covers the flags.

Install

./install.sh                      # into ~/.local/bin
./install.sh --prefix /usr/local/bin
./install.sh --uninstall

Shell completions

Completions for zsh, bash and fish are installed to each shell’s
conventional directory. Nothing is sourced and no rc file is edited,
so whether they take effect depends on your shell already looking
there:

• bash — ~/.local/share/bash-completion/completions, found
  automatically by bash-completion 2.x.

• fish — ~/.local/share/fish/vendor_completions.d, found
  automatically.

• zsh — ~/.local/share/zsh/site-functions, which is not in the
  default fpath. Add it in ~/.zshrc, above the line that runs
  compinit:

  fpath=(~/.local/share/zsh/site-functions $fpath)
  autoload -Uz compinit && compinit
  

  The order is the part people get wrong: compinit only reads
  directories that were in fpath when it ran, so appending
  afterwards silently does nothing. compinit does notice a newly
  populated directory and rebuilds its cache on its own, so there is
  no need to delete ~/.zcompdump.

Installed under a different --prefix? Substitute <prefix>/../share
for ~/.local/share throughout.

That setup is per-shell, not per-package: once zsh is looking in
site-functions, every unflab package that ships a completion works.

About this build

Pure Rust, statically linked apart from macOS’s own system libraries —
no package manager, no runtime dependencies. Upstream disables
jemalloc on macOS, so unlike some Rust builds there is no allocator
library to link against.

Built with PCRE2 support (rg --pcre2 / -P), statically linked the
same way as everything else here — matching upstream’s own release
binaries. This enables PCRE-specific regex syntax such as
backreferences and lookaround that ripgrep’s default Rust-regex engine
doesn’t support.

Upstream also publishes prebuilt macOS binaries; this package exists so
rg installs the same way as everything else here, not because it was
hard to get.
