Running Objective-C with Ruby on Rails

I want to execute the following Objective-C code in a Rails application:

CFMutableStringRef inputString = CFStringCreateMutableCopy(kCFAllocatorDefault, 32, CFSTR("")); CFLocaleRef locale = CFLocaleCreate(kCFAllocatorDefault, CFSTR("ru")); CFStringTransform(inputString, NULL, kCFStringTransformStripDiacritics, false); CFStringLowercase(inputString, locale); NSLog(@"%@", (NSString *)inputString); CFRelease(locale); CFRelease(inputString);

It basically outputs a lowercase, non-contact version of the input string. I am running on a Snow Leopard server.

How can I do this (without using MacRuby, which seems to be redundant here)? I have heard about Ruby extensions, but cannot find any resources in my case.

Instead of creating an application, you should turn on and off in one instance of Rails, you can write your application using other communication methods, for example, named pipes:

Or follow the Ruby C extension path:

You may be able to do this with ffi , but for this you need to enter a set of functions. A tiny test case for calling a Core Foundation function:

 require 'ffi' module CF extend FFI::Library ffi_lib '/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation' attach_function :CFAbsoluteTimeGetCurrent, [], :double end puts CF.CFAbsoluteTimeGetCurrent
