Re: foreach loop and creating files with "$

Take a look at $_ in perlvar. Frankly, I don't hesitate to use $_. But then most of my code is fairly straight forward procedural code without much scoping challenge. I am sure someone here has run into an issue or two making use of $_, but I certainly have not.

I personally don't like the 'visual' of $temp$_, so would handle it differently, but I don't see anything functionally wrong with it.

`my $file = "file"; my $temp = "temp"; foreach (1..5){ open $file, '>', "$temp" . "$_"; print $file "THIS IS DATA"; }` [download] or `my $file = "file"; my $temp = "temp"; foreach my $end (1..5) { open $file, '>', "$temp" . "$end"; print $file "THIS IS DATA"; }` [download] (not tested) Personal preference only... ...the majority is always wrong, and always the last to know about it...

What's wrong with always quoting "$vars"? Less clutter, too: `open $file, '>', $temp . $_;` [download]	[reply] [d/l]

First with $_ then without `use Path::Tiny qw/ cwd path tempfile /; ## in cwd path( "temp$_" )->spew("THIS IS DATA") for 1 .. 5; ## in $TMP directory tempfile( 'tempjamesXXXX' )->spew("THIS IS DATA") for 1 .. 5;` [download]	[reply] [d/l]
