( #3333=superdoc: print w/ replies, xml ) Need Help??
I have just started to delve into Perl, and going through the following example:
#!/usr/bin/perl use strict; use warnings; use Path::Class; my $dir = dir('foo','bar'); # foo/bar # Iterate over the content of foo/bar while (my $file = $dir->next) { # See if it is a directory and skip next if $file->is_dir(); # Print out the file name and path print $file->stringify . "\n"; }
Reading the code....
my $dir = dir ('test1');

# local scalar dir is assigned by dir ('test1')
the dir on the RHS, being possibly from Path::Class (CPAN)
while (This condition hold true)
# Simple While

my $file = $dir->next $dir scalar de-references the function next ? HOW ?
HOW do i guess that next would indeed be written as next and not next(), etc
since there is NO reference/example for "next" in
Class.pm Same goes for stringify, or is_dir()
Now in this case is_dir() seems again to be a function, but how come its called differently

Thanks,
