Openbox:Pipemenus:Dirsmenu

Another pipe menu for recursive directory listing. I tried to keep the code as simple and short as possible. It uses Perl's File::Find to get the directories and files in the current directory and lists them in alphabetic order while making each directory a submenu. It escapes special characters and prints the underscore correctly (unlike obbrowser).

You can adjust options such as starting directory, show hidden files or show '..'

dirsmenu:

#!/usr/bin/perl
# Openbox menu to recursively list directories and files.
use File::Basename;
use File::Find;
use Cwd 'abs_path';

sub say { print @_, "\n"; }
sub print_files;
sub print_dirs;
sub fix_html (\$);
