Summary
Function: string llStringTrim( string src, integer type );| 330 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a string that is src with leading and/or trailing white space (spaces, tabs, and line feeds) trimmed from it.
| • string | src | |||
| • integer | type | – | STRING_TRIM* flag(s) |
| Constant | Description | |
|---|---|---|
| STRING_TRIM_HEAD | 0x1 | Trims spaces off the beginning. |
| STRING_TRIM_TAIL | 0x2 | Trims spaces off the end. |
| STRING_TRIM | 0x3 | Trims spaces off the beginning and end. |
Caveats
Examples
Returns the number of leading and trailing spaces on a string (not particularly useful but shows how to use the function). <lsl> default {
state_entry()
{
llListen(4, "", llGetOwner(), "");
}
on_rez(integer a)
{
llResetScript();
}
listen(integer chan, string name, key id, string msg)
{
//test for and remove wrapping single or double quotes
if(~llSubStringIndex("'\"", llGetSubString(msg,0,0)))
if(llGetSubString(msg,-1,-1) == llGetSubString(msg,0,0))
msg = llDeleteSubString(msg, -1, 0);
//track the length
integer length = llStringLength(msg);
//trim msg (not necessary to store these to variables but makes reading easier)
string trim_left = llStringTrim(msg, STRING_TRIM_HEAD);
string trim_right = llStringTrim(msg, STRING_TRIM_HEAD);
string trim = llStringTrim(msg, STRING_TRIM);
//output the results
llOwnerSay("Initial length = " + (string)length +
"\nLeading Spaces = " + (string)(length - llStringLength(trim_left))+
"\nTrailing Spaces = " + (string)(length - llStringLength(trim_right))+
"\nTrimmed Message = \"" + trim + "\"");
}
}
</lsl>Notes
The following examples will make the same result. <lsl> string src = " Duh "; st = llStringTrim(src, STRING_TRIM_HEAD); st = llStringTrim(st , STRING_TRIM_TAIL); </lsl> <lsl> string src = " Duh "; st = llStringTrim(src, STRING_TRIM); </lsl>
This is because (STRING_TRIM_HEAD | STRING_TRIM_TAIL) == STRING_TRIM.
