Easy %case Q
|
I want the %case to work like the #case command
| Quote: |
#CASE @joincmd {join} {rescue}
if the variable @joincmd is 1 (or 3,5,7...) the string join is returned, otherwise the string rescue is returned. |
Thus i want to:
%case(@variable_containing_a_number, "if it is a odd return this", "if it is not odd return this")
But like that it wont work. |

%if(%mod(@variable,2),"odd","even")
%case(%eval(%mod(@variable,2)+1),"odd","even")
I like the %if version better. |

Actually the behaviour of #CASE where it repeats is a bug. No one ever reports it because those that have found it, like you, thought it was useful. Still, it is counter to the specification of #CASE.

Really? The earliest helpfiles I've seen (early version 6) made it seem like that was an intentional feature.

As a matter of fact i was looking at the current documentation today for another problem and they also made it seem like the wrapping was intentional. Of course, it could just be Zugg doing a bit of that age old software joke. "It's not a bug, it's a feature!"

CASE
Syntax: #CA index command1 [commandn]
Allows you to select a command from a list to be executed. The index parameter determines the command to execute from the list given by command1..commandn. If index is greater then the number of commands, it wraps around. For example, if there are four commands and you ask for the fifth, the first is returned. This allows you to use the predefined variable %random to select a random command.
If the index is negative, results are undefined.
CASE examples
#CASE 2 {first command} {second command} {third command}
sends the string second command to the MUD
#CASE @joincmd {join} {rescue}
if the variable @joincmd is 1 (or 3,5,7...) the string join is returned, otherwise the string rescue is returned.
#CASE %random {Hello} {Hi there} {Hiya} {Hi}
returns a random string from the given list to the MUD. |
To me it looks quite how it should work, only that the function does not work right. |
