Print class and instance methods declarations from Objective-C implementation

printmethods.awk

#!/usr/bin/env awk -f
# print class and instance methods declarations from implementation
# Usage: ./printmethods.awk class.m or awk -f printmethods.awk class.m

/^[[:space:]]*@implementation/ {
  implementation = 1;
}

/^[[:space:]]*@end/ {
  implementation = 0;
}

/^[[:space:]]*[\-\+]/ {

    method = 1;
    collect = "";
  }

    p = index($0, "{");
    if(p == 0) {

        collect = $0
      else
        collect = collect $0 "\n";
    } else {

Try embedding clang and use the AST walkers :)

That would be much nicer yes, this was a quick hack for someone on stackoverflow :) Do you have any documentation how to use the AST talkers? seams as the include files for clang is not included with Xcode :( Found this http://llvm.org/devmtg/2010-11/Gregor-libclang.pdf which seams nice but maybe old? C++ and libast may be a better choice?
