Re: [MacRuby-devel] Exposing c structs and functions
John, thanks for the ideas. Currently, I am using a simple Obj-C class with methods instead of a struct and functions. That works OK, but it is not the best solution, especially in those cases where the framework would be used by Obj-C code instead of MacRuby code and where speed is a concern. A struct/ function approach is really ideal. I am afraid I don't understand the tutorial example concerning BridgeSupport files and how that might apply to structs and functions. As you said, the documentation on the BridgeSupport web page is limited. Before I go down that road, I'd love to know how involved the process is, see an example of how it works, and so on. Perhaps Laurent could shed some light? Jim ___ MacRuby-devel mailing list [email protected] http://lists.macosforge.org/mailman/listinfo.cgi/macruby-devel
Re: [MacRuby-devel] Exposing c structs and functions
Your best bet is to take a look at the bridgesupport files for most system frameworks and learn from those. They are found inside Resources/BridgeSupport. Nonetheless, it would indeed be very nice if a more elaborate guide could be written. Eloy On Dec 19, 2008, at 4:45 PM, Jim Getzen wrote: John, thanks for the ideas.

Here this works.
If it doesn't work then paste a few lines more.

Re: [MacRuby-devel] Exposing c structs and functions
OK, I decided to devote a little time to see if I could make any
headway with BridgeSupport. It doesn't seem too terribly complicated,
but I have run into a problem.
My framework is called ZenGL, so I first created a struct in ZenGL.h
based on NSPoint:
typedef struct _ZPoint {
float x;
float y;
} ZPoint;
I also created a ZPointMake function:
ZPoint ZPointMake(float x, float y);
Then, I rebuilt the framework. Fine so far.
Next, I created an XML ZenGL.bridgesupport file using Foundation.xml
(in /Library/BridgeSupport/) as an example. Here are the contents:
">
encoding='{_ZPoint="x"f"y"f}'
type='{_ZPoint="x"f"y"f}'/>
I placed ZenGL.bridgesupport in the folder with my built MacRuby app
and added this code to load it:
load_bridge_support_file './ZenGL.bridgesupport'
(Going back to my xml, I originally did not include a 'type' attribute
for the struct since the NSPoint example in Foundation.xml did not
have one, but I received an error when running the load_... command.
Not sure why.)
All seems well, but when I try this code from MacRuby:
zp = ZPointMake(10.0, 10.0)
I get this error:
`ZPointMake': wrong number of arguments (2 for 0) (ArgumentError)
My ZPointMake function definition in the xml sure looks right to me,
based on the examples in Foundation.xml, so what have I done wrong?

Re: [MacRuby-devel] Exposing c structs and functions
Hi Jim,
Sorry for the late response!
Indeed the best way to make your C API available from MacRuby is to
cover it with a BridgeSupport file and load it, MacRuby will
reconstruct the corresponding API in the Ruby world. BridgeSupport
descriptions are language agnostic and can be loaded in other
scripting languages too.

Looks like your XML description is not correct, function_arg and
function_retval are invalid elements.
Try:
">
encoding='{_ZPoint="x"f"y"f}'
type='{_ZPoint="x"f"y"f}'/>
You can learn more about the BridgeSupport format by reading the
gen_bridge_metadata(1) and BridgeSupport(5) man pages.

Re: [MacRuby-devel] Exposing c structs and functions
Hi Laurent,
First, why does the Foundation.xml use the elements "function_retval"
and "function_arg" instead of just "retval" and "arg"?
Second, I used the xml you suggested, but I now get this error:
`ZPointMake': unrecognized octype `{_ZPoint="x"f"y"f}' (RuntimeError)
I have read the man pages (I had to learn what a "man page" was
first!), but I didn't see anything that would solve that error.

FYI, man pages are great at reminding folks of options, details, etc. They are less useful as tutorials. In any case, it often helps to skim a related set of man pages (ie, follow SEE ALSOs) a couple of times, as that helps things to sink in... -r -- http://www.cfcl.com/rdmRich Morin http://www.cfcl.com/rdm/resume [email protected] http://www.cfcl.com/rdm/weblog +1 650-873-7841 Technical editing and writing, programming, and web development ___ MacRuby-devel mailing list [email protected] http://lists.macosforge.org/mailman/listinfo.cgi/macruby-devel

Re: [MacRuby-devel] Exposing c structs and functions
Hi Jim,
You're probably looking at an old BridgeSupport file. function_retval
and function_arg do not exist anymore since a very long time, and were
replaced by retval and arg.
You should be able to get the latest Foundation bridgesupport file
from here:
/System/Library/Frameworks/Foundation.framework/Resources/
BridgeSupport/Foundation.bridgesupport
Back to your new problem, I think your struct element is also wrong
(uses the old definition). I would look at the Foundation file and try
to mimic it. Also, you can generate the file by using
gen_bridge_metadata (from the command line) if your code is a
framework or a shared library. Finally, if you opt by writing the file
by yourself, it is always good to run an XML validation pass (the DTD
location is part of your XML declaration).

Re: [MacRuby-devel] [MacRuby] #141: Building MacRuby 0.3 - Rake fails during openssl compilation
Have you tried removing /Library/Frameworks/MacRuby.framework after
cleaning the build location, but before starting the new build?
I have had trouble with builds before and sometimes clearing out the
old MacRuby.framework helps.

You should keep this, but only return the class if it's not a Ruby class
