What is wrong with this if statement, it is driving me around the twist.


It seems no matter what value $action is set to... it still performs the actions inside the if statment!! I proved that $action is not equal to 'Editor' with the included print statement.

'==' should be 'eq' - '==' tests numerically, 'eq' tests alphabetically.

I was just commenting to my girlfriend on what kind of perl guru you must be to whip out statements like:

@top3 = (sort { (split ',', $a, 3)[-1] <=> (split ',', $b, 3)[-1] } @array)[0 .. 2]; off the top of your head.

Thanks for the help!!!!

If you are wondering what it does then instead of assigning everything to variables first, it just works "on the fly" so to speak.

[0 .. 2] means that only elements 0, 1 and 2 will be added to the array (only the top 3 were asked for).

(split ',', $a, 3)[-1] ....that splits the data and [-1] is the last element (which is the number that the user wanted to sort by)

Its always easy in retrospect

Thanks Paul, that makes sense. Obviously these kinds of statements are 2nd nature to you also.

In time I will be able to read it like my name. I find the string/array/regex type of statements to be the most interesting (and foreign) to me.

Something I will have to get my teeth into soon

I'd like to think so but if they were I would have given that solution in my first reply but I didn't think of it :)

Looking back it is obvious though.
