SplitLine

Function: string SplitLine(string source, string separator, integer stride);

Returns a string split by inserted 'new line' escape code at separator positions to portions of at least stride length.
In other words, a line can be split up to several lines at positions where separator string is found, each line with a length of at least stride characters.

• string	source	–	source string
• string	separator	–	split separator string
• integer	stride	–	split stride

Specification

<lsl> string SplitLine(string _source, string _separator, integer _stride) {

   integer offset= _stride;
   integer sourceLen = llStringLength(_source);
   integer separatorLen = llStringLength(_separator);

   while (sourceLen > _stride)
   {

integer split = llSubStringIndex(llGetSubString(_source, offset, -1), _separator); if (split != -1)

       {

_source = llInsertString(_source, offset + split + separatorLen, "\n"); sourceLen = llStringLength(_source) - offset; offset += split + _stride + 2; }

       else sourceLen = -1;
   }
   return _source;	

} </lsl>

Example

Trivial example to listen to any chat from the object owner for source values and respond lines split at space (" ") positions using 10 characters stride value. <lsl> // Insert code of SplitLine user function here

default {

   state_entry()
   {
       llOwnerSay("Enter text");

llListen(0, "", llGetOwner(), "");

   }

   listen(integer _chan, string _str, key _id, string _msg)
   {
       llOwnerSay(_msg + "\nsplit to:\n" + SplitLine(_msg, " ", 10));
   }

} </lsl>
