Forums Scripts & Popups isnum question

im makeing auth dialog for script
so naturaly i dont want numbers to be allowed to start with
in usernames
problem is that mirc doesnt get that

if (1sometext isnum) { bla }
contains number :S

so any other solution to this (just not isalpha, coz nicnames can and do use numbers, but not in beginning)

?

Why not use $left with isnum?

if $left(nick,1) isnum { do this }
else { do something else }

That will check if the first character in the nick is a number or not. The characters that are recognized as numbers are the numbers 0 - 9, and the decimal (aka period/dot).
If there are others, then I don't recall them at the moment, or I haven't come across a situation where they've been detected.

if $xor($regex(nick,/^\d/),0) { :tongue:

ahh thanks hehe
forgot mirc has left anf right :S

b1nk no offece, i would use yours, but since i dont understand regex i tend to always use simpler code that
is unedrstandable to me.

thanks for effort too !

mIRC has a !not operator in if-statements.

if (!$regex(nick,/^\d/)) {

-genius_at_work

or to save 1 more byte:
if ($regex($nick,/^\D/)) echo -a nickname doesn't start with a number

or to save 7 more bytes:
if ($calc($nick)) echo -a nickname doesn't start with a number

:-) (this is actually faulty but hey i was just being smart.)

you mean nickname DOES start with a number? :P fails with 0 though, $calc(0nick) = $calc(nick) = 0

good thinking though, in fact you could shorten it further with $or(nick) which would have the same effect as $calc(nick) and mess up with 0

Likewise:
$r(1,$nick) Will return $null if $nick doesn't start with a number but fail with 0nick :tongue:.
