Using Ruby in Lua¶ ↑

NONE OF THIS IS IMPLEMENTED¶ ↑

IF YOU HAVE SUGGESTIONS, TELL ME!¶ ↑

Ruby is different in Lua in that there is a single Ruby VM, whereas there can be many Lua states. This is represented in Lua as an object in the global table named 'ruby'.

The first thing you need to require the RubyLuaBridge library. With this object, you can run Ruby code, load Ruby libraries, and access Ruby objects.

require 'rubyluabridge'
print(ruby)    # => userdata: 0x219083

With this ruby object, you can get and set variables and invoke functions.

ruby.NilClass    --
ruby.a = 5       -- 
ruby.print       --

ruby.eval("print 'hello world'"     # => nil
ruby.eval("1")                      # => 1
ruby.eval("'test'")                 # => "test"
