Repository navigation

# Homebrew formula for offshoot, served straight from this repo as a tap:

# brew tap sricola/offshoot https://github.com/sricola/offshoot

# brew install offshoot

# The explicit URL form of `brew tap` accepts a repo that is not named

# homebrew-*, and brew picks up formulae from the tap's Formula/ directory.

# Source build (depends_on "go" => :build) rather than per-arch bottles:

# it version-bumps by editing url+sha256 only, and mattn/go-sqlite3 compiles

# its bundled SQLite amalgamation via cgo, so no sqlite dependency is needed.

def caveats

<<~EOS

`offshoot diff` shells out to sqldiff, which Homebrew ships as its

own formula (not part of `sqlite`):

brew install sqldiff

Everything else, including `offshoot diff --summary`, works without it.
