Re^2: Regex for weird characters

The idea is okay, but why match the whole string if it's sufficiant to fail as soon as one character fails? So instead of

$text !~ /^[a-z0-9,]*$/i
[download]

this should give the same result:

$text =~ /[^a-z0-9,]/i
[download]

$\=~s;s*.*;q^|D9JYJ^^qq^\//\\\///^;ex;print

you could shorten Skeeve's regex further using character classes, acutally it's the same length cause I added spaces ;) `$text =~ /[^\w\d\s,]/;` [download] Update: switched /w for \w (++ to graff for pointing out my typo) "Cogito cogito ergo cogito sum - I think that I think, therefore I think that I am."

You absolutely can not use perl's shortcut character classes. \w matches different things depending on your locale. If you have a German locale, for instance, it will match ß.	[reply]
