brewx is a single Rust binary that runs Homebrew executables on demand.
It resolves the executable to a Homebrew formula using an embedded
db.json, installs the formula if needed, and then execs the requested
tool.
Example:
./target/release/brewx deno --help
- Build the database from cached Homebrew data:
./build-db.py
- Build the binary:
cargo build --release
- Run a Homebrew tool:
./target/release/brewx deno --help
build-db.py fetches Homebrew API responses (cached in cache/brew.sh)
and writes db.json in the repository root. The Rust build embeds this
file in the binary, so rebuild after regenerating the DB.
db.json contains a schema version, a generation timestamp, and a map of
executable names to their selected Homebrew formula. The builder uses
install analytics to pick the most popular formula when there is more
than one candidate.
- brewx embeds
db.jsonat build time; rebuild after regenerating it. - The database is derived from Homebrew manifests and analytics data.
