in thread stuck on regexp

To make the username no longer than 30 characters use this:


This will match when the first character is [A-Za-z] and is followed by 1 to 29 characters of form [-.\w] (thus making the total length of username from 2 to 30 characters)

And yes, \w caters for [a-zA-Z0-9_]

Replies are listed 'Best First'.

    if single character usernames are allowed, {1,29} should be replaced by {0,29}

[Dumu]: hello jedikaiti
[Dumu]: got it. Anyway. Perl question. Can you use binmode more than once with an open filehandle to read a file first in binary mode, then in utf8 mode?
[ambrus]: Dumu: you can use binmode multiple times, but mostly at the start before you read things. it would be strange to change the io layers after you've already read things, and might not work too well.
[ambrus]: Dumu: why would you want to read the same file both in binary mode and utf8 mode?
[Corion]: Dumu: Yes, but switching needs to be done with caution, as you might read half an UTF-8 character in binary mode, and then switch to utf8 mode...
