Forums Feature Suggestions Choosing identifier scope

I think it'd be nice it we could change the scope an identifier is called in to the calling script, for example:



$im would be the same as $ifmatch, rather than $null because $ifmatch was called in the scope of the calling script, not the $im identifier.

In case of $ifmatch/$ifmatch2/$v1/$v2 it already works:

alias im return $ifmatch

//if (5 isnum) echo -a $im

($ifmatch is a sort of global variable, much like &binvars)

In fact I can't think of any case where this cannot be done the above way, except for $1, $2, $1- etc but who would want to make a replacement for them? They are as short as they can be already. Can you think of any other example where this would be useful?

Your post made me look at my code again. It was a stupid mistake on my part:



The ! shouldn't have been there.

Now I'm thoroughly confused. I never saw any "!" in any of your posts and I'm not sure how it fits in here. The code in your 2nd post works fine, but I don't see how it is an example of the usefulness of the proposed feature.

I'm thinking perhaps hixxy realised that we're able to "return $ifmatch" hehe.. and just realised the code that he/she originally used, was the reason it didn't work. That's just my guess though..

Heh that does make perfect sense. Funny how sometimes you miss the obvious...
