Hmm…this is an interesting case. It's possible that we've not fully looked into calling super with explicit block args. Can you see if this can be reduced to a simple, self-contained example? Either way, it would be good to have a Trac ticket for this issue.

Thanks!

Hi

I can repeat the issue. It is working good with Sinatra 1.0.0 ->

Morning all,

I'm having a go at setting up a macRuby app that utilizes Control Tower and Sinatra.
I've no problem installing the gems for either, but the current versions of each seem to be mutually exclusive, as they require specific versions of Rack that do not match.

I poked around and couldn't identify any reasons why a new version of Rack wouldn't work, so I forked/edited/built/installed ControlTower 1.0.me and gave it a go. Control tower by itself seems to be doing Great. However, if I attempt to load sinatra for the never-been-done-before hello world example, I get this:

/Users/kpoorman/Library/Developer/Xcode/DerivedData/ControlTowerTest-gpdchdkfcdvfgdczhlapcihrrkpc/Build/Products/Debug/ControlTowerTest.app/Contents/Resources/rb_main.rb:20:in `block': wrong number of arguments (1 for 0) (ArgumentError)
from /Users/kpoorman/Library/Developer/Xcode/DerivedData/ControlTowerTest-gpdchdkfcdvfgdczhlapcihrrkpc/Build/Products/Debug/ControlTowerTest.app/Contents/Resources/rb_main.rb:17:in `<main>'

Fast forward 30 minutes, and I've narrowed it down to a block of perfectly working MRI-ruby:

return super(*args, &block) if respond_to? method_name

Specifically, if I start loading Sinatra components in macirb, it works great until you hit a Set or Enable method call, which in turn invokes the Delegator mixing ¡K etc down to line 1601 of sinatra::base (version 1.4.0) which is above.

So, I suppose I should use your time wisely and ask a couple of direct questions --

1: what, if anything, am I doing wrong?
2: Is this version of sinatra incompatible with Control Tower?
2a: what version of sinatra *is* compatible ?
3: is this a Macruby bug?
3a: I like to think of myself as a fairly advanced ruby developer, with excellent knowledge of meta-programming and the sinatra framework, what I don't understand, is what's wrong with that code ?

Thank you for your time!

-Kevin
