Forums Bug Reports $* bug (if no /tokenize called)

If I didn't call /tokenize and tried to //echo -a $* it doesn't return any error msg.

This isn't a bug. /command $* is run $0 times: if $0 is zero (meaning /tokenize wasn't used or parameters weren't passed etc), /command will be run zero times, so nothing happens. This isn't an error though, so no error message should be displayed. If you want to see whether there are $N's, just check $0:

is it possible to check if ($*) ? because I want to pass it in an identifier with many parameters.

you can't directly include $* in constructs like if/while or identifiers, but what qwerty implied with /scid -r was that you could form an escaped command including $*, then use the fact that /scid re-evaluates its command:



this tends to get messy, and you also need to be careful as always when passing arbitrary data to things like /scid as all your $N tokens will be evaluated as code.. but if you know what you're doing it can be handy :>

From the beginning I thought there is a way to check if ($*) ain't null without passing it /scon. because I want to use some script in an identifier. whatever.

thanks both of ya

then why don't you use what qwerty showed? if $0 is non-0 then parameters have been passed.

but if you also want to check against things like $youridentifier(,,) where $0 is 3 but each $N is null you could check



which forces there to be at least one non-$null parameter

Like you said that would still make $* trigger on null values
here a tighter workaround
[code]
alias blink {
var %n = $regsubex($str(a,$0),/(.)/g,$+($!len($\n),$chr(32)))
if (0 !isin $(%n,2)) && ($0) echo -a $*
}
[code]

Doesn't matter how many parameters you specify as long as they are all not $null.
Well "doesn't matter" taken into account $len($N)<space> which is 9 characters long you should reconcider doing it another way if $0 is going to be over 94 ;P
//noop $blink( [ $gettok($str($+($!r(a,z),$chr(44)),94),1-,44) ] )
highest ammount of parameters you can send with this.

Never thought $* could be called without /tokenize. Its ok. I'll use another method for the code I'm working on. thanks mpd.

if 94 is an unreasonable limit (lol ) you could take advantage of error handling:



edit: then theres that bug with using $* twice in the same routine :P oh well, could always retokenize but kinda defeats the purpose.. :S

I already submitted the code on mirc.net and just waiting for approval.

This one supports more tokens (173) but uses $lf as separator, which is uglier:
Based on the fact that if $N is $null, $N<anything> becomes $null too (and assuming no $lf is in the params).

Btw, you need $istok() instead of isin (for cases like $len($5) = 10).

doh :tongue:
