Summary
Function: integer like( string value, string mask );
See if one word matches part of another.
Returns an integer that is TRUE if value tested positive for mask, otherwise it is FALSE.
| • string | value | |||
| • string | mask |
You can, for example, loop through a list, passing it extracted values from the list and the mask, and it will let you pull out items from the list which are a valid match according to the mask criteria you specified.
Specification
integer like(string value, string mask) { integer tmpy = (llGetSubString(mask, 0, 0) == "%") | ((llGetSubString(mask, -1, -1) == "%") << 1); if(tmpy) mask = llDeleteSubString(mask, (tmpy / -2), -(tmpy == 2)); integer tmpx = llSubStringIndex(value, mask); if(~tmpx) { integer diff = llStringLength(value) - llStringLength(mask); return ((!tmpy && !diff) || ((tmpy == 1) && (tmpx == diff)) || ((tmpy == 2) && !tmpx) || (tmpy == 3)); } return FALSE; }
Examples
like("Susie", "Sus%"); //will return true, for any value starting with "Sus" like("Susie", "%Sus%"); //will return true, for any value containing "Sus" like("Susie", "%Sus"); //will return false. This example is looking for a string ending in "Sus". like("Susie", "Sus"); //will return false. This example is looking for a string matching only "Sus" exactly.
