rpl.rb

Reverse-Polish-Lisp inspired language in ruby

Install

gem install rpl

Usage

  • rpl --help
  • run RPL: rpl
  • by default rpl persists its state in $XDG_DATA_HOME/rpl.rb/env.rpl which is created if needed (if $XDG_DATA_HOME isn't set ~/.local/share/ is used)

Development

To run REPL locally: rake run

To run the test suite: rake test

To build gem: rake gem

known bugs

TODO-list

  • Language:
    • pseudo filesystem: subdir/namespace for variables . 'a dir' crdir 'a dir' cd vars
  • SDL-based graphic environment/API
