Hi Jonathan,
If you want an open source framework, use CorePlot
(http://code.google.com/p/core-plot/). If you're willing to pay money
for something that looks awesome, is easier to use and
well-maintained, check out DataGraph (both the App and Framework:

Hi Scott,
The problem is due to the way the macruby Pointer class handles types,
which apparently is due to an LLVM issue... The Pointer class is
defined in compiler.cpp. See this comment:

Hi Steve (et al),
So, there are a couple things going on here. Cocoa classes use the
concept of a "designated initializer" method, which is a name for the
instance method that calls the initializer method of the superclass.
This chain continues until you hit [NSObject#init]. To figure this out

Hi Carlo,
In case it helps, you might be able to use one of the existing
keychain wrappers / code rather than rolling your own (listing):

There is also a nice keychain wrapper for iPhone, but I'm not sure if
it works on OS X:

As Ben points out, KVO really shines when you need to keep a UI in

Those symbols are defined in the Carbon framework. Try compiling with:
cc shortcut.m -o shortcut.bundle -g -framework Foundation -framework

Be careful not to confuse the TableView delegate with the DataSource delegate.

Seems like a good idea that would be useful even outside of HotCocoa.
Especially for simple cases, I think if Obj-C had blocks, this would
be a good place to use them. For more control, the delegate pattern
actually works really well. It's good that you have a way to do both.

In this case, you could use the KVC[1] (key-value coding) accessor
(#valueForKey:) to access the ivar.

When you built MacRuby, did you have the RUBYOPT env set?
If so, unset it. See the comments for this:

Hi Pete,
Since you have an NSData object, you should be able to convert it to a
String (NSString) and then use unpack. For example:
socket_port = NSSocketPort.alloc.initWithTCPPort(1)
addr = socket_port.address
addr_str = NSString.alloc.initWithData(addr,
encoding:NSString.defaultCStringEnco
I think that if you need to make use extensive use of C
functions/libraries, then the least painful route is to wrap this
functionality in Objective-C classes. Writing Objective-C classes

Unless there is an issue in the library code, usually building for at
least ppc/x86 only involves choosing from a drop down in xcode or a
few compiler flags on the command line. It shouldn't take much time
and is only a few extra bytes.

CGLRendererInfo is a pointer to a struct:
typedef struct _CGLRendererInfoObject *CGLRendererInfoObj;
try creating a pointer to void or to the struct:
info = Pointer.new_with_type("^v") # void *info;
or
info = Pointer.new_with_type("^{_CGLRendererInfoObject=}") #
