(normally i disapprove of such shenanigans, but then I also disapprove of using recursion, so it's moot. This should keep the heap from ballooning as quickly (which will help in LSO but not in Mono)) |

User-Defined Function: integer uSubStringLastIndex( string vStrSrc, string vStrTst );
Returns a integer that is the positive index of the last vStrTst within vStrSrc
- vStrSrc: source string to check
- vStrTst: string to look for
if vStrTst is not found in vStrSrc -1 is returned.
the index of the first character is 0
Code:
- LSO: 182 bytes
- MONO: 1024 bytes
<lsl>integer uSubStringLastIndex( string vStrSrc, string vStrTst ){
integer vIdxFnd =
llStringLength( vStrSrc ) -
llStringLength( vStrTst ) -
llStringLength(
llList2String(
llParseStringKeepNulls( vStrSrc, (list)vStrTst, [] ),
0xFFFFFFFF ) //-- (-1)
);
return (vIdxFndCaveats
- Performs a literal match (case sensitive).
- Wildcards and RegEx are not supported.
- Attempting to match an empty string ("") will return 0 instead of -1.
Notes
- This function is operates exactly like llSubStringIndex (including caveats), from the opposite end of the string.
