alef 0.25.37

//! Homebrew test_app generator.
//!
//! Generates a registry-mode-only test_app at `test_apps/homebrew/` that
//! exercises a Homebrew tap's CLI formula and (optionally) FFI formula.
//!
//! Emitted files:
//!
//! - `Brewfile` — declares tap + formulae for `brew bundle install`.
//! - `run_tests.sh` — installs via Brewfile and runs the configured CLI tests.
//!   When `ffi_formula` is set it also compiles and runs `ffi_smoke.c`.
//! - `ffi_smoke.c` — minimal C program linking against the FFI formula.
//!   Only emitted when `ffi_formula` is configured.
//! - `README.md` — describes the test_app.
//!
//! This generator is registry-mode only.  In local mode it emits a single
//! stub `README.md` explaining why generation was skipped.
//!
//! # Configuration (`alef.toml`)
//!
//! ```toml
//! [crates.e2e.registry.packages.homebrew]
//! tap = "myorg/tap"
//! cli_formula = "my-tool"
//! # ffi_formula is optional; omit to suppress FFI sections entirely.
//! ffi_formula = "libmy-tool"
//!
//! # Optional: explicit CLI tests.  When absent, a single --version check is emitted.
//! [[crates.e2e.registry.packages.homebrew.cli_tests]]
//! name = "version"
//! command = "$CLI_FORMULA --version"
//! expect_contains = "$VERSION"
//! ```
