Re: Descending a directory tree, returning a list of files

Hi, Why not use use File::Find::Rule to get the list of files? Here's how I get a list of XML files in all sub-directory starting from the current location:

use File::Find::Rule;

my $xml_finder = File::Find::Rule->new()->name(qr/(.*?)\.xml$/i)->star
+t(".");

while (my $file = $xml_finder->match()  ) {
  # Do whatever you want with your file name  
}

I hope this helps!

Definitely agree ... “file finders” (“directory tree walkers”) are the way to go, and there are quite a few good ones in CPAN. There’s just no point in doing such a mundane chore “by hand.”

There’s just no point in doing such a mundane chore “by hand.” Unless you need to do it "by hand" because the modules on CPAN don't do what you need to do. Perhaps I missed it, but I didn't find any of the "file finders" modules (as you called them) that would handle long file paths (>260 characters) in Windows. Looking at possibly using Win32::LongPath to roll my own code to search through a Windows filesystem and handle the long path names. Until I hit this long path issue, I probably would have agreed with what you said.	[reply]

Yeah, but chances are, you still don't need to do it "by hand" :) see Win32::Unicode , https://metacpan.org/pod/Win32::Unicode::Dir#findW-code-dir, with Path::Tiny like Re: links in pathnames under Windows 8 , Re^5: Trouble with File::Find::Rule (win32 unicode overload file test operators), Re^5: Is File::Find Unicode-(Conformant\|Compliant\|Enabled\|Capable)?, mocking overloading filetest operator callback -f -d -e -X, ...
