python - Problem with number/type of arguments passed to an overloaded c++ constructor wrapped with swig -

-

i trying wrap c++ class (let's call "spam") written else swig expose python. after solving several problems, able import module in python, when try create object of such class obtain following error:

 foo = spam.spam('abc',3) traceback (most recent call last):   file "<stdin>", line 1, in <module>   file "spam.py", line 96, in __init__     = _spam.new_spam(*args) notimplementederror: wrong number of arguments overloaded function 'new_spam'.   possible c/c++ prototypes are:     spam(unsigned char *,unsigned long,bool,unsigned int,sstree::io_action,char const *)     spam(unsigned char *,unsigned long,bool,unsigned int,sstree::io_action)     spam(unsigned char *,unsigned long,bool,unsigned int)     spam(unsigned char *,unsigned long,bool)     spam(unsigned char *,unsigned long)

googling around, realized error caused type of arguments , not number (which quite confusing), still cannot identify. suspect problem lies in passing string first argument, have no idea on how fix (keep in mind know no c/c++).

try with:

%typemap(in) (unsigned char *) = (char *);

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."
