Minor bug: %item and numbers larger then the number of items in the list
|
#loop 4 {#show %i : %item("one|two",%i)}
Can we have this fixed back to the way it was in zMud (i.e. automatically did the %mod math for you) pretty please? (As always, sorry if this has already been brought up, searching for "item" "string list" is less then useful.) |

I just tried that on zMUD:
| Code: |
1 : one
2 : two
3 :
4 : |
and CMUD:
| Code: |
1 : one
2 : two
3 :
4 : |
I get the impression that on zMUD it goes one,two,one,two for you?
If it does, I'd consider that a bug, not a feature. |

The only place I've ever heard of the wraparound counter is in the #CASE command...

| Code: |
#func loopL %item(%1,%if( %mod( %2, %numitems( %1))=0, %numitems( %1), %mod( %2, %numitems( %1))))
#loop 9 {#show %i : @loopL("one|two|three",%i)} |
In fact, Fang would you help file this somewhere? I've wanted this function in the past myself... |

Drat, you're right, I was completely getting confused with #CASE.
Although come to think of it, it would still be useful, like Arminas says the math involved is kind of spammy (not difficult, just annoying). |

This won't be changed, sorry. There are many cases where it's very important to return a null value when accessing elements outside the range of the array. And the MOD can be done even easier using the \ operator:
| Code: |
| #loop 4 {#show %i : %item("one|two",((%i-1) \ 2)+1)} |
|

That's great Zugg.
I wasn't really asking for a change in the function. I was just Hoping that the example I gave would be added to the %item help.
Your example would be much better. I have just bumped my head on that problem a few times and having forgotten I would look at the help thinking, "Why isn't this mentioned?". |
