[MacRuby-devel] Appscript and pathname translation

2012-04-18 Thread Robert Schaaf 
Hello again, Macruby community!

I'm trying to rewrite a program that drives Excel with appscript, and running 
into the problem of translating back and forth between HFS and POSIX pathnames. 
 The old Appscript module included a MacTypes module, and these two 
translations were provided.

1. to go from POSIX to HFS:  

hfs_pathname  = MacTypes::FileURL.path(posix_pathname).hfs_path

2. to make the round trip back to POSIX:  

posix_pathname  = 
DefaultCodecs.unpack(DefaultCodecs.pack(hfs_pathname).coerce(KAE::TypeFileURL)).path

Do I need to go to the scripting bridge for this?  This is Core Foundation 
stuff, and I'm totally at sea.  

Any help would be greatly appreciated.

Re: [MacRuby-devel] Appscript and pathname translation

2012-04-18 Thread Alan Skipp 
Hi Bob,
If at all possible I'd try and avoid the conversion. If this is not feasible, 
this could help:

def posix_from_hfs(hfs)
url = CFURLCreateWithFileSystemPath(nil, hfs, KCFURLHFSPathStyle, false) # 
final argument is whether the path is a directory or not
url.path
end

def hfs_from_posix(posix)
url = NSURL.fileURLWithPath posix
CFURLCopyFileSystemPath(url, KCFURLHFSPathStyle)
end

The first method needs reworking, as it assumes that the HFS path is not a 
directory.
I've only did a very brief test of the above code, but it seems to do the job.

[MacRuby-devel] Help with class files

2012-04-18 Thread Robert Rice 
Help,

I have a recurring problem with corrupted class files created by Xcode 3.2.4 
and I don't know much about class files.

I start having this problem whenever my application become large and I try to 
change the inheritance of some MacRuby files. Occasionally, the change will 
cause Interface Builder to crash immediately without an error message but 
usually the problem manifests itself by not updating the class inheritance 
information in IB. Even after selecting "Reload All Class Files", IB will show 
the old inheritance. Deleting my file from Xcode and adding it back in still 
does not fix the problem.

The only way I know to fix the problem is to copy all of my source file into a 
new project but this is getting to be more than annoying. Is there a way that I 
can force Xcode to rebuild all class files for my project?

Thanks,
Bob Rice

Hi Watson,

I tried the 4/18 nightly build and it still fails, although it seems to have 
gotten further. Now the last line in the files window is:

./usr/local/share/man/man1/macrubyd.1

Thanks,
Bob Rice

 Hi,
 
 I'm still using Xcode 3.2.4. Does MacRuby now require Xcode 4?
 
 I backed up to the 1/1/2012 nightly. The 2/21/2012 nightly didn't have 
 Xcode MacRuby templates.
 
 Thanks,
 Bob Rice

Re: [MacRuby-devel] Installer Fails

2012-04-18 Thread Robert Rice 
Hi Watson,

Thanks for you help. I guess that if Xcode 3 won't still work for me then it's 
time for me to upgrade to Xcode 4. After installing the latest Xcode 4 the 
latest MacRuby nightly install ran without a problem.

Now I will have to learn Xcode 4. It seems that Xcode 4 is showing me which 
imported XIB files were corrupted instead of just crashing like IB did.

Thanks,
Bob

 We updated at several times about packager which include the Xcode3
 template into installer,
 so nightly build which you have might lost the Xcode3 template.
 
 please try with latest.

 Hi MacRubyists,
 
 It's been a long time since I posted on this forum. I've been doing 
 well with MacRuby. But I ran into a problem trying to bring my 
 installation up-to-date. updated I found that I could only update to 
 the 2/21/2012 nightly build. After that the installer gives me a 
 message "Installation Failed" with nothing descriptive of the problem. 
 Anyone know what changed?

[MacRuby-devel] Elegant initialization

2012-04-18 Thread Josh Voigts 
Hey, first post to the list, woot!

I've run into a little bit of a snag. Is there an elegant way of
building an initializer similar to this one in macruby? (assuming I'm
subclassing an NSView object)


- (id)initWithFrame:(NSRect)frame controller:(AppController *)ctrlr
{
    if (self = [super initWithFrame:frame]) {
        controller = ctrlr; // deliberately weak reference.
    }

    return self;
}

Re: [MacRuby-devel] Compile error

2012-04-18 Thread Joshua Ballanco 
It's hard to know what exactly is going on here without seeing more of your 
project. Some things you can try though is to look through the build settings 
for your project for the string bundle1.o. It's not clear to me though why you 
would want to be linking a .o file?

Have you tried "Clean All"? (I forget the exact wording in the Xcode 3 menu…but 
it's there with "Clean")

Re: [MacRuby-devel] Elegant initialization

2012-04-18 Thread Joshua Ballanco 
Welcome! Hope you enjoy your stay!

You can write Obj-C-ish methods in MacRuby the same way you call them: using 
Ruby's hash syntax. The only other caveat is the difference between "super" in 
Ruby and Obj-C. In Obj-C, "super" is the superclass. In Ruby, it is shorthand 
for calling the same method in the superclass. Also, in Ruby, you are not 
allowed to redefine self. Finally, you generally don't need to worry about weak 
references in Ruby (since cycles can be handled by the GC). So your above 
method translated would look like this:

def initWithFrame(frame, controller: ctrlr)
  initWithFrame(frame)
  @controller = ctrlr
  self
end

Cheers,

Josh
