Forums Bug Reports Parsing bug with $eval

I'm not sure if this is intended behavior or not, so someone correct me if it is please. I'm using Mirc 6.34 on Windows XP SP 2.



I get the following error: * Too few parameters: $rand

However, the code below works as expected.



For some reason $eval isn't properly evaluating %i.

Thanks for your time.

If I were to guess (and I don't have mIRC up at the moment to check), I would say that the "," in %i is causing difficulties via $eval.

$eval($i,1) --> $eval(1,100,1) which would evaluate to a scalar (possibly "1", but I would have to test this in mIRC).

Thus, only one parameter is being passed to $rand when you use $eval.

When you are using [ %i ], "1,100" is also being evaluated, but there are no expectations of "," notation - so there is no confusion over the placement of the "," and thus no ambiguity on the result.

As I said, these are my first thoughts and I have not tested this.

Cheers,

It's not a bug. Evaluation brackets are very different from $eval(), in that only the former control the order of evaluation ($eval merely controls the depth). Anything inside [] is pre-evaluated, ie is evaluated before the normal evaluation of identifiers/variables. This isn't the case with $eval.

$rand($eval(%i,1)) means "call $rand with one parameter that is evaluated once".

$rand( [ %i ] ) (roughly) means "evaluate %i before even determining the number of parameters in $rand"

Ahh, I see. I had assumed that using the brackets and $eval were the same thing. Apparently, they are not.

Thanks for the help.
