Download the script here.

Just run passing the URL, for example:

$ python u.py www.coding.com.br

http://u.nu/72mpd

Easy your life by putting the script on your $PATH and execution (+x) file mode. Worth check the API from other services:

• bit.ly
• migre.me (brazilian company)
• is.gd
• tiny.cc
• tinyurl

For simple variables types like int or float is just equal to 0 or 0.0 respectively. Now, suppose that you have a “large” struct and doesn’t want to set each member  individually… you could just type “={0}” which means that the first member is explicitly initialized to zero and the remaining members are implicitly initialized, also zero. Let’s see an example:

typedef struct
{
int a;
char c;
char s[10];
int *ptr;
} data;

When you initialize with:

data d;

You got some random value like:

{a = -1208298748, c = -12 ‘\364′, s = “\317\372\267\230\353\377\277\351\203\004″, ptr = 0xb7e94cc5}

When you type:

data d = {0};

You’ll have each struct member initialized to zero.

{a = 0, c = 0 ‘\000′, s = “\000\000\000\000\000\000\000\000\000″, ptr = 0×0}

You can learn much more about designated inits [section 6.26] on GCC docs.

I haven’t found the solution for my problem (for wordpress, drupal and joomla there are so many) so I resolved it and now I’m posting if somebody can’t do it or just wanna some copy/paste

 location ~ ^/wiki {
 	root /path/to/wiki;
 	index wikka.php;
 
 	if (!-e $request_filename) {
 		rewrite ^/wiki/images/(.*)$ /images/$1 break;
		rewrite ^/wiki/templates/(.*)$ /templates/$1 break;
 		rewrite ^/wiki/3rdparty/plugins/freemind/(.*)$ /3rdparty/plugins/freemind/$1 break;
 		rewrite ^/wiki/3rdparty/plugins/wikkaedit/(.*)$ /3rdparty/plugins/wikkaedit/$1 break;
 		rewrite ^/wiki/(.*)$ /wiki/wikka.php?wakka=$1 break;
 		break;
 	}
 }

A brief explanation:

on line 1 we setup where our wiki is located, on our case /wiki, so in line 2 we give full path to where the wiki’s file are located on the filesystem and line 3 we says our index will be wikka.php once Wikka Wiki just redirect index.php to wikka.php (ok I don’t mind why they don’t put the contents of wikka.php on index.php and its over ).

line 5-12 we configure the rewrite rules, on line 5 is the condition what to do when there is no file or symbolic link when a URL is acessed, if its matched the following rules are processed:
line 6-10: rules to ensure that static content like css, js and images won’t be redirected to wikka.php.
line 11: the main rule, that will redirect all URLs to wikka.php so it process and show the output for each wiki page.

I don’t why (I’m new to Nginx) even using the condition if(!-e $request_filename) I need to put the rules to ensure that static content will be reached, if I discover, I update this post, but these rules are working for me under Nginx 0.7.67 and Wikka 1.2-p1
