Re: create directory with input

File::Spec provides a convenient interface to constructing directory names and filenames and it works in many operating systems:

$path = File::Spec->catfile( @directories, $filename );

In the present case it would go like this:

use Modern::Perl qw/2017/;
use File::Spec;
my $directory_name = 'testdir';
my $path =
  File::Spec->catfile( qw/C: Users darkblack Desktop A/, $directory_na
+me );
say $path;
[download]

Output (in Windows): C:\Users\darkblack\Desktop\A\testdir

But running under Unix it will return C:/Users/darkblack/Desktop/A/testdir

File::Spec::Functions provides an even easier functional interface.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
