MXRuby

mruby wrapper in Elixir

Usage

mruby = MXRuby.new()

{:ok, "foo"} = MXRuby.eval(mruby, """
  class Foo
    def foo
      123
    end
  end
""")

{:error, "NoMethodError: undefined method 'bar'"} = MXRuby.eval(mruby, "Foo.new.bar")

{:ok, "123"} = MXRuby.eval(mruby, "Foo.new.foo")

{:ok, "4"} = MXRuby.eval(mruby, "1 + 3")

Passing arguments

mruby = MXRuby.new()
{:ok, res} = MXRuby.eval(mruby, "$mxruby.inspect", arg1: "val1", arg2: "val2")
IO.puts(res)

Output:

{:arg1=>"val1", :arg2=>"val2"}

Argument keyword list should have only binaries as values.
