Rubinius support

[edmundhighcock]

Hi all,

Thanks for your continued work on this very useful gem.

Just out of interest, has anyone had a look at making this Rubinius compatible? How much work would it be? I'm interested in looking at it at some point, but just wanted to see what, if anything had been attemped.

A quick attempt to build it in Rubinius seems to a show a lot of the source files building without a hitch (see below), so maybe it's not too bad.

I have also posted in the Rubinius forums to try and get help from the rbx developers.

rubinius/rubinius#2006 (comment)

[edmundhighcock]

The patch below was sufficient to allow rake compile to work with rubinius... the RBASIC macro is now deprecated in 2.x according to this page:

http://docs.ruby-lang.org/en/2.1.0/README_EXT.html

However, of course, I'm not sure if rb_obj_hide and rb_obj_reveal are supported in 1.x.

So rake compile works with rbx 2.0.

rake test gives the error below, which is something I've not seen before, coming from MRI. Google doesn't reveal anything on it.

An exception occurred running /home/edmundhighcock/.rvm/gems/rbx-2.5.2@global/gems/rake-10.4.2/lib/rake/rake_test_loader.rb:

wrong number of arguments (ArgumentError)
