Re: finding visible length of string?

Why not bypass the problem of the length by using \r?

print "\r\033[32m coloured! \033[m ";

Note the extra spaces on the end to ensure that if one string is shorter than that which preceeded it, the remnents of the preceeding one get erased.

A variation on this would be to just clear the whole line between prints. Something like: `$\|++; my $clear = "\r" . ' 'x80 . "\r"; print "quux"; sleep 1; print $clear, "foo"; sleep 1; print "\n";` [download] -sauoq "My two cents aren't worth a dime.";	[reply] [d/l]

I was using "\b" x $i , but I was deleting up to a point which changed as the script progressed, with or without colours in the string (Aaarrgh!). A horrible mess! Removing the whole line seems the simplest way. <slaps forhead!> Thanks, O'holy ones!	[reply]
