# slosh — Homebrew formula (a *formula*, not a cask: casks are for prebuilt
# .app/.pkg/.dmg drops, formulae are for things brew builds and puts in bin).
#
# This file is the source of truth. `contrib/brew-release` rewrites the three
# stanzas below (url/version/sha256) for a new commit or tag and copies the
# result into the tap repo, which is what users actually tap:
#
# brew tap sl0p-foo/slosh
# brew install slosh
#
# Try it without publishing anything:
#
# brew install --build-from-source contrib/homebrew/slosh.rb
class Slosh < Formula
desc "Terminal multiplexer with detachable sessions and programmable pane chrome"
homepage "https://sl0p.foo"
# GitHub's archive of a commit is deterministic per ref: same ref, same
# bytes, so the sha256 below stays honest. Pinned to a full commit id rather
# than a branch, because a branch tarball changes under you and brew would
# keep the stale one.

Start from the shipped config:
mkdir -p ~/.config/slosh && cp #{opt_share}/slosh/config.kdl ~/.config/slosh/
Then: slosh (attach to session "main", creating it if needed)
C-a ? (the keys) C-a p (every command by name)
