GIML

Gazay's incomplete Minimalistic Language.

By Alexey Gaziev.

Objectives

Smallest and incomplete language for big but simple config files. It should be so simple that you can write fast parser for it in few LOC and without heavy dependencies.

Strange behavior of Module#attr_reader

If run this with ruby test.rb with MRI, Jruby, and in MRI irb: true

If run in Jruby irb: false

I think it can be related in following failing rails tests, but I'm not sure:

  3) Error:
AttrInternalTest#test_naming_format:
