[CMUD 2.18]The trouble with %proper
|
%proper returns incorrect value if first character is not a letter.
EDIT: until it gets fixed this will do the job
| Code: |
| #FUNC proper($string) {#RETURN %subregex($string,"^(\w)(.*)","%upper(%pat(1))%pat(2)")} |
|

It helps to give details on exactly what incorrect value is returned. I tried %proper("123abc") and it returned 23abc. (Oddly enough, it has the exact same behavior in zMUD.)

The fact that value its returning is not the correct value seemed sufficient.
It only has to be off by 1 to be broken.
I was certain Zugg could determine what was wrong given the information I originally provided.
But for the curious:
If the original first character is not a miniscule alphabetic character the ordinal value of the first character returned will be 32 less than the original
if this value falls below zero it loops around to 255 and decrements from there.
| Code: |
| #echo %ascii(%proper("0")) |
displays 16 |
