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).
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(src, STRING_TRIM_HEAD); string trim_right = llStringTrim(src, STRING_TRIM_HEAD); string trim = llStringTrim(src, 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 + "\""); } }
Notes
The following examples will make the same result.
string src = " Duh "; st = llStringTrim(src, STRING_TRIM_HEAD); st = llStringTrim(st , STRING_TRIM_TAIL);
string src = " Duh "; st = llStringTrim(src, STRING_TRIM);
This is because (STRING_TRIM_HEAD | STRING_TRIM_TAIL) == STRING_TRIM
