wordwrapping - string segments
|
The game i am playing, for some reason, whats hardcoded linebreaks after x amount of characters, when creating custom items.
What would be the easiest way to break up a string like that, but only on spaces. |

Interesting question!
How about this? Assuming that it breaks at 80 or less, and the string you want to break is $mystring...
| Code: |
$wordlist = %replace($mystring," ","|")
$testline = ""
$lineout = ""
#WHILE (%numitems($wordlist) > 0) {
#WHILE (%len($testline) <= 80 AND %numitems($wordlist) > 0)) {
$lineout = $testline
#IF ($testline = "") {
$testline = $wordlist.1
} {
$testline = %concat($testline," ",$wordlist.1)
}
}
#IF ($lineout = "" AND %numitems($wordlist) > 0) {
#SAY Warning! This line is cannot be broken at less than 80 characters!
$lineout = $wordlist.1
}
#SENDRAW $lineout
$testline = ""
$lineout = ""
#CALL %pop($wordlist)
}
|
One possible downside of this code is that it will strip out any leading or trailing spaces, if that is a problem. |

Actually, Vijilante wrote something like this for me a while back.
| Code: |
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
<func name="format" copy="yes">
<value>#RETURN %subregex($string,"(.{1,79})(?:$| )",%concat("\1",%crlf))</value>
<arglist>$string</arglist>
</func>
</cmud>

Much neater, in my opinion. Then all you have to do is @format(" This line is a string that needs to be formatted correctly and includes three spaces at the beginning of the line.") |

After tweaking, this is my final result:
| Code: |
$len=%if(%2, %2, 79)
$string=%replace($string, %crlf, " ")
$string=%concat(" ", %trim($string))
#RETURN %subregex($string,%concat("(.{1,", $len, "})(?:$| )"),%concat("\1",%crlf)) |
