Comment(by eloy.de.en...@…):

 In order to prevent this, you can pass the --format-executable to macgem
 when you install gems. The rake bin would then be named ‘macrake’. Though
 there is an issue with rubygems that it doesn't remove the bin when
 uninstalling a gem, but that's a minor issue imo.

Re: [MacRuby-devel] memory leaks

Hi Jakub,

Sorry for the late reply. I have been switching homes and was without internet 
access.

Investigating memory leaks in a MacRuby app can be problematic because of the 
GC. (The same problem is also valid for pure Objective-C apps running in GC 
mode.) What you may see as leaks could potentially be false positives. Numbers 
reported by top(1) can also sometimes be wrong.

In general, memory leaks can easily be induced by the user, although it is 
unlikely here. There has been some work on eliminating memory leaks in the 0.6 
release but there might still be some around.

What I would do:

1) build MacRuby trunk (just run rake macruby)
2) in the same directory, run your app like this (here, Foo): $ 
DYLD_LIBRARY_PATH=. MallocStackLogging=1 MallocStackLoggingNoCompact=1 
/path/to/Foo.app/Contents/MacOS/Foo 
3) use your app a little bit, then when you're reading to measure leaks: $ 
leaks Foo > /tmp/Foo.leaks

Then, attach /tmp/Foo.leaks here.

> Here's a minimal version of the app:

How should I use it? It looks like it's asking me some kind of 
username/password.

Re: [MacRuby-devel] Using the SystemConfiguration framework

2010-07-06 Thread Laurent Sansonetti 
I'm afraid there is no other way currently than wrapping this API in ObjC as 
John suggested.

We are working on a better BridgeSupport system but it won't be available soon.

 It's complaining that there aren't any inline functions in the
 SystemConfiguration framework. This is the command I ran and the
 output I received:
 
 $ gen_bridge_metadata -f
 /System/Library/Frameworks/SystemConfiguration.framework -F dylib -o
 SystemConfiguration.dylib
 No inline functions in the given framework/library, no need to generate a 
 dylib.
 
 However, this doesn't make any sense to me. The documentation clearly
 lists lots of inline functions. C isn't my best language, so maybe I'm
 misunderstanding something...

Comment:

 Looks like we properly encode the sequence, so I guess it's a bug
 somewhere else.

 {{{
 $ macruby -e 'p "\u{01}".bytes.to_a'
 [240, 144, 128, 128]
 $ ruby1.9 -e 'p "\u{01}".bytes.to_a'
 [240, 144, 128, 128]

 Vincent do you have an idea?

[MacRuby-devel] Fullscreen sample app

2010-07-06 Thread Michael Jackson 
Hi all,

I created a fullscreen sample app in MacRuby, and I thought someone
else might be able to get some use out of it.

http://mjijackson.com/2010/07/fullscreen-macruby
http://github.com/mjijackson/Fullscreen

It's basically a port of someone else's Objective-C code, but it uses
NSApp's presentation options to control automatic hiding/showing of
the menu bar and dock instead of doing it manually. If anyone has any
feedback for me, I'd love to hear it.

Enjoy,

Michael

Re: [MacRuby-devel] Fullscreen sample app

2010-07-06 Thread Laurent Sansonetti 
Hi Michael,

Thanks for porting it :) Would you mind if we bundle your sample as part of the 
MacRuby sample code? If you agree, would you also be willing to license the 
code under the Ruby license? (which is the default license for everything in 
MacRuby, so no need to mention it).
