Ironruby core - Jan 2010 - Differences between 1/ MRI and 2/ IronRuby+JRuby

Hello,

maybe someone can shed some light on that - the question is: is there a
setting to make IronRuby works the same way MRI Ruby does by default for
what I''m describing below ? I don''t think it''s a bug
(but well maybe it is,
just wondering).

Using this script http://gist.github.com/290538 , MRI has a different
behaviour than JRuby or IronRuby.

The script will work just fine in MRI, whereas in JR/IR you''ll get:

(erb):2: undefined local variable or method `version'' for main:Object
(NameError)
    from :1:in `eval''
    from /opt/local/share/java/jruby/lib/ruby/1.8/erb.rb:743:in
`result''
    from binding-error.rb:19

(erb):1: undefined method `version'' for main:Object (NoMethodError)
        from C:/IronRuby/lib/ruby/1.8/erb.rb:716:in `result''
        from binding-error.rb:19
        from :0:in `eval''

It''s just like values.send(:binding) is doing nothing.

any thoughts ?

thanks,

-- Thibaut

AFAIK that shouldn''t work in MRI either

Hey Ivan,

thanks for your answer.

I redid the test on:
- Mac OS X (mri ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10.0.0])
=> http://gist.github.com/290538#file_test_on_mac_os_x.txt
- Windows 7 (mri ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32])
=> http://gist.github.com/290538#file_test_on_windows.txt

And it works on both apparently...

There must be a reason... Which version of Ruby/IRB are you using ?

mine was on windows with ruby 1.9.1 though.. I don''t have a 1.8 around
to
see if that same test works with 1.8 on windows. In 1.9.1 the tweaked stuff
works too

Thanks - that''s probably a 1.8 specific thing... We''ll see
what others have
to say on Monday :)

Thanks for your tests!

It should work as soon as we push the latest source out.

Hi Thomas,

thanks for the update (note that I''m in no hurry on these bugs -
I''m just
pushing what I find as I go, based on the MSI release, and using workaround
whenever necessary).

cheers,

We should be doing an MSI in the next few weeks.
