Re: [MacRuby-devel] unrecognised defined?

[Ben Schwarz]

Hey Laurent,

Would it be possible for the error thrown to post some line /  
character information (backtrace?)

Or can I turn some verboseness on for debugging these issues somehow?

Cheers,

Ben

Hi Ben,

This is a missing feature in the compiler, in the way we compile the  
defined? expression.


It's easily reproducible here:

$ ./miniruby -e 'p (defined? FOO && 42)'
unrecognized defined? arg: 21 (NODE_AND)Abort trap

I filed a test_vm case.

Now, it looks like the code you found this problem is bugged.

if defined? RUBY_ENGINE && RUBY_ENGINE == 'jruby'

should probably be written as

if (defined? RUBY_ENGINE) && RUBY_ENGINE == 'jruby'

otherwise, it seems to be the equivalent of

if defined?(RUBY_ENGINE && RUBY_ENGINE == 'jruby')

which is probably not what the code wants to do.

Hey folks,

After installing the 'grit' gem I required' it in macirb and  
received the following:


b...@homeslice ~ Ϟ macirb
irb(main):001:0> require 'grit'
	unrecognized defined? arg: 21 (NODE_AND)fish: Job 1, 'macirb'  
terminated by signal SIGABRT (Abort)



Which, I believe is responding to line 12 in grit.rb – http://github.com/mojombo/grit/blob/master/lib/grit.rb#L 
12
Is this a bug that should be logged? I've tried defined?  
RUBY_ENGINE in macirb and it appears to execute without a problem


Cheers,

Adding backtrace information is in the TODO list for 0.5.

Not currently. I tend to use a lot the following line when searching
for a MacRuby bug:
STDERR.puts "#{__FILE__}:#{__LINE}"

My understanding is that backtraces are really high on Laurent's TODO list
and I also use the same trick as Vincent when I need to debug some of my
code. (and yes, it's very frustrating and I can't wait to have some decent
backtraces and hopefully a debugger)

Awesome stuff lads.
Perhaps this could be added to your .irbrc files to have it always  
present until backtraces are available?

That wouldn't do any good though, as __FILE__ and __LINE always point  
to the file and line of the binding that it's evaluated from. So  
putting it in .irbrc at line 3 would mean it would print ".irbrc: 3",  
not what you'd expect…

Good point Eloy, I wasn't really thinking there...

[MacRuby-devel] RubyKaigi 2009 slides

[Vincent Isambart]

Hi,

Just to say I uploaded my RubyKaigi 2009 slides on slideshare:
http://www.slideshare.net/vincentisambart/rubymac

The presentation was entirely done in Japanese (with someone
translating in English on IRC) but the slides are bilingual
Japanese/English

The video is also available on Ustream but there is no translation and
you will only see the screen, not me presenting:
http://www.ustream.tv/recorded/1833285

PS: Yes I know it was two months ago, but well nobody asked for my
slides so I did not take the time to upload them :P.

Cheers,
Vincent

Hello Alex...

I watched that peepcode screencast a couple of days ago and build  
the app from scratch with macruby 0.5. If it is of any help, I put  
the project directory on my ftp:


ftp://witwenmacher.com/TwittRb.zip

The app works so far, except for the "require 'cgi'" in  
TwittRbDelegate.rb. That one throws an ArgumentError in  
define_method. If you comment it out the application will run but be  
unable to send tweets. I wasn't able to find a solution for that yet.


I get the same error Bjoern does on an 10.5 installation with MacRuby  
0.5, but the original nib-related errors are coming from MacRuby 0.5  
running on Snow Leopard. Bjoern, what OS are you running this on?

I am running this on OS X 10.6.1 with the newest MacRuby 0.5 and XCode

Re: [MacRuby-devel] Nib issues on Snow Leopard

[Matt Aimonetti]

The incomplete CGI implementation seems to be causing the issue:

$ macruby -e "require 'CGI'; puts CGI.escape('foo bar')"
wrong number of arguments (1 for 0) (ArgumentError)

I'll look into it tonight.
