Word wrap function -- is there already one?

You've got a string such as:

"All instances of each separator will be used to parse the string"

64 characters

using Xyzzy text (10 char variation), two prims per line, i can display on a sign board i'm making up to 20 chars per line.

So with 64 characters in above for instance (string just an example, will change daily), I need 4 lines (64 / 20 = 3, plus 1 line for the leftover 4 characters.

But I don't want to just messily break a word right in the middle like th
is.

I've already started on a function, experimenting with

llParseString2List(wordstringstart, [" "], []);

to break out words based on spaces after having broke stuff down into sets of 20 characters...

started because i didn't want to be lazy....


but nor do I want to be dumb and re-invent the wheel, if anyone knows of a piece of script already out there that does this.

(I know there's not a lot of text manipulation functions as SL is not what you would normally define as a document-rich environment, hehe.)

Try this function:

list WrapText(string pcText, integer piWidth) {
    list     laLines = [];
    integer  liIndex;
    integer  liKeep;        // Specifies if we keep the char pointed at or not
    
    while (llStringLength(pcText) > 0) {
        liIndex = piWidth;
        liKeep = 1;
        if (llStringLength(pcText) > piWidth) {
            liKeep = 0;
            while ((liIndex >= 0) && (llGetSubString(pcText,liIndex,liIndex) != " "))
                --liIndex;
            if (liIndex <= 0) {
                liIndex = piWidth;
                liKeep = 1;
            }
        }
        laLines += [llGetSubString(pcText,0,liIndex - 1)];
        pcText = llDeleteSubString(pcText,0,liIndex - liKeep);
    }
    return laLines;
}

Probably can be optimized a bit, but it works.

Optimized more?? hehe. Before I left to go out for dinner, I was already at like 497 lines :}

Well, not quite, but that script is quite optimized compared to the hoops I was leaping through! grin.

Many thanks, works like a charm!

using string handling to add a word at a time up to your limit, then inserting a new line might work better.

or pararsing the string to a list, loop and count until you hit your limit, insert a newline, reset your count, and then continue.... until you dump the list to a string

all depends on how much text is coming in
