# Do your dangerous IPFW work in the upper pane.
# When done, switch to lower pane (Crtl-B, down arrow) and kill it with Ctrl-C

string replacement

How to implement this substring replacement rule?

  • %% is replaced with % and %x is replaced with #

which would do, for example,

abc %x def      => abc # def
abc %%x def     => abc %x def
abc %%%x def    => abc %# def

abc %%%%x def => abc %%x def

Chaining the PHP ternary
<?php
// Some people object to this use of the ternary. I think it's fine so long as each
// condition-value pair fits nicely on one line. If so then the structure is highly
// expressive. The value $var takes is very obvious. The logic that
// this condition => that value, this condition => that value, etc. is plain to see.
$var =
condition1 ? 'value1' : (
condition2 ? 'value2' : (
condition3 ? 'value3' : (

detecting urls
<?php
$letnum = '\p{L}\p{Mn}\p{Mc}\p{Nd}';
$sym = '+&@#/%=~_|$';
$pnct = '?!:,.-';
$c1 = "[$letnum$sym$pnct]";
$c2 = "[$letnum$sym]";
// then the regex pattern is, so to speak:
// \b(?: https?:// | www\. ) (?: \($c1*\) | $c1 )* (?: \($c1*\) | $c2 )
// with xui options.
