I'm working on a domain-specific language (DSL) for non-programmers. Non-programmers make a lot of grammar mistakes: they misspell keywords, they don't close parentheses, they don't terminate blocks, etc.
I'm using ANTLR to generate my parser; it provides a nifty mechanism for handling RecognitionExceptions…

Hello,
I am trying to parse integers and to access their value in antlr 3.2.
I already found out how to do this in Java:
//token definition
INT : '0'..'9'+;
//rule to access token value:
start : val=INT {Integer x = Integer.valueOf( $val.text ).intValue(); }
;
... but I couldn't…

I am writing a program in Objective-C (XCode 3.2, on Snow Leopard) that is capable of either selectively blocking certain sites for a duration or only allow certain sites (and thus block all others) for a duration. The reasoning behind this program is rather simple. I tend to get distracted when I…

Hi,
I made an Objective-C project for the iPhone. I had only one cpp class, the soundEngine taken from some Apple demo. Now I'm trying to merge OpenFeint which is coded in Objective-C++. As soon as I drop in the code without even referring to it from my code, when I hit Build, my Objective-C code…

Does anyone know of a way to add additional attribute types to the @property keyword without modifying the compiler? Or can anyone think of another way to genericize getter/setter creation?
Basically, I have a lot of cases in a recent project where it's handy for objects to lazily instantiate their…

I am developing an iPhone application and I use HTML to display formatted text.
I often display the same webpage, but with a different content. I would like to use a template HTML file, and then fill it with my diffent values.
I wonder if ObjectiveC has a template system similar to ERB in Ruby.
That…

Say I have 2 protocols, MyProtocol and MyProtocolCB:

- (void) func;
@end
@protocol MyProtocol <NSObject>
- (void) register:(MyProtocolCB*) cb;
@end
I'm receiving this…
