Re: count subset of chars in a line

in reply to count subset of chars in a line

There's a very pretty way to count them with the tr// operator, my $vowel_count = tr/AEIOUYaeiouy//; If you want the character list in a variable, you need to string-eval: my $foo_count = eval "tr/$foo//";

Argh, I knew I'd seen a tidy way to do it somewhere. Sorting out the parameter handling for the sub was good exercise though :-). Perl is Huffman encoded by design.	[reply]
