Function: string WrapText(string source, integer length);
Splits a long text string into lines whose character length you get to specify. Useful, for instance, for long floating text to make it tidier. It will not split words at odd places but instead look for the space in the text nearest to the length you have specified.
Example: string myWrappedText = WrapText(Title, 25);
Specification
string WrapText(string pcText, integer piWidth) {
list laLines = [];
integer liIndex;
integer liKeep; // Specifies if we keep the char pointed at or not
integer liLen = llStringLength(pcText);
list llSearch = [" ", "\n"];
while (liLen > 0) {
liIndex = piWidth;
if (!(liKeep = (liLen <= piWidth))) {
while ((liIndex >= 0) && (-1 == llListFindList(llSearch, (list)llGetSubString(pcText, liIndex, liIndex))))
--liIndex;
if (liIndex <= 0) {
liIndex = piWidth;
liKeep = 1;
}
}
laLines += llGetSubString(pcText, 0, liIndex - 1);
pcText = llDeleteSubString(pcText, 0, liIndex - liKeep);
liLen -= (1 + liIndex - liKeep);
}
return llDumpList2String(laLines,"\n");
}
