Building CLI Apps for Everyone
summary
Explains how mruby-cli compiles Ruby into a statically linked, self-contained binary for Linux, macOS and Windows, using mrbc ahead-of-time bytecode and Docker-based cross-compilation. Shows concrete numbers: typical Ruby hello world boots ~41ms on MRI versus ~3ms with mruby, and an example macOS binary is ~421 KB. Describes workflow files (build config, gemspec, generated C bootstrap), testing with mtest unit and shell integration tests, and current limits around native extensions and gem compatibility.
