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>
