objective c - Gcc not including Object.h -

-

i starting on doing objective-c gcc (so far used xcode).

#include <objc/object.h>   @interface integer : object   {   int integer;   }   - (int) integer;   -(id) integer: (int) _integer;   @end 


#import "integer.h"   @implementation integer   - (int) integer   {       return integer;   }   - (id) integer: (int) _integer   {       integer = _integer;   }   @end

and once try compile stuff this:

main.m: in function ‘main’:   main.m:8: warning: ‘integer’ may not respond ‘+new’   main.m:8: warning: (messages without matching method signature   main.m:8: warning: assumed return ‘id’ , accept   main.m:8: warning: ‘...’ arguments.)   main.m:8: warning: ‘integer’ may not respond ‘+new’

seems me inclusion of object.h did not quite work. searched thee includes object.h , got this:

find /usr/include/ -name object.h    /usr/include//objc/object.h

also gcc output hints compiler is searching in path.

 #include "..." search starts here:    #include <...> search starts here:    /usr/local/include    /usr/lib/gcc/i686-apple-darwin10/4.2.1/include    /usr/include    /system/library/frameworks (framework directory)    /library/frameworks (framework directory)   end of search list.   gnu objective-c version 4.2.1 (apple inc. build 5664) (i686-apple-darwin10)         compiled gnu c version 4.2.1 (apple inc. build 5664).   ggc heuristics: --param ggc-min-expand=150 --param ggc-min-heapsize=131072   compiler executable checksum: 84137cc00ce86c64ee80a91a006f61ae   main.m: in function ‘main’:   main.m:8: warning: ‘integer’ may not respond ‘+new’   main.m:8: warning: (messages without matching method signature   main.m:8: warning: assumed return ‘id’ , accept   main.m:8: warning: ‘...’ arguments.)   main.m:8: warning: ‘integer’ may not respond ‘+new’`\

what overlooking?

if gcc couldn't find object.h, give error indicating that. problem apple removed of methods object (or @ least interface it) in objective-c 2.0. instead, should subclass nsobject , include foundation framework.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
