Building CLI Apps for Everyone
summary
Claims a practical toolchain: mruby-cli plus a Docker build image produces a single statically linked binary that can cross-compile for Linux OSX and Windows. Measured startup drops from about 40 milliseconds (MRI hello world) to 3 milliseconds and example OSX binaries are ~421 kilobytes. Demonstrates building and testing (unit mtest and bintest), shows a real reuse: jruby-launcher rewritten as njruby using mruby-cli, and notes mrbgems and stdlib limitations.
