as another responder mentioned File::Slurp, i want to say it contains a
read_dir function (note the _ in the name). it does a slurp of a dir and
always filters out . and .. . i have plans to have it take an optional
qr and grep the dir list for you. something like this:
my @dirs = read_dir( $dirpath, qr/\.txt$/ );
again, i agree these functions should not be named new() as open and
readdir have more meaning. how could you tell you were opening a file vs
a dir with just open? many coders may not even know that open in p5 will
work on a dir! you just open the file and can read the raw dir data
which will likely look like garbage unless you have the correct
filesystem c structures to decode it. so you must have some way to
designate to the open/new that this is a dir.
the whole issue of portable paths is another problem but i can't address
that.
thanx,
