tinyrb

A tiny subset of Ruby with a Lua'esc VM.

Everything in TinyRb should run in the big Ruby. (except bugs and things that don't comply to the principle of least surprise.) But not everything in the big Ruby should run in tinyrb.

This is a work in progress and not usable for “real things” yet. See TODO for a couple of those things that need to be done.

github.com/macournoyer/tinyrb #tinyrb on freenode

Install

make
make test # optional
./tinyrb -h

What WON'T be in tinyrb (tiny patches accepted)

  • for

  • redo, retry

  • if … do, while … do, etc

  • alias keyword (see alias_method)

  • undef keyword (see undefine_method)

  • throw, catch

  • Alternate string delimiters (%q, %Q, etc.)

  • heredoc strings

  • Parallel assignment (a, b = 1, 2)

  • as . (Class::new)

  • Character code literal (?c)

  • protected, private, public (yes everything is public, mind you)

  • ObjectSpace

  • $SAFE (but Sandbox mode at the VM level)

  • … others to come for sure.
