NAME

       File::Fu - file and directory objects

SYNOPSIS

       The directory constructor:

	 use File::Fu;

	 my $dir = File::Fu->dir("bar");
	 print "$dir
"; # 'bar/'

	 my $file = $dir + 'bar.txt';
	 print "$file
"; # 'bar/bar.txt'

	 my $d2 = $dir % 'baz'; # 'barbaz/'
	 my $d3 = $dir / 'bat'; # 'bar/bat/'

	 my $file2 = $dir / 'bat' + 'foo.txt'; # 'bar/bat/foo.txt'

       The file constructor:

	 my $file = File::Fu->file("foo");
	 $file->e and warn "$file exists";
	 $file->l and warn "$file is a link";
	 warn "file is in ", $file->dir;

ABOUT

       This class provides the toplevel interface to File::Fu directory and file objects, with operator overloading which allows precise path
       composition and support for most builtin methods, as well as creation of temporary files/directories, finding files, and more.

       The interface and style are quite different than the perl builtins or File::Spec.  The syntax is concise.  Errors are thrown with croak(),
       so you never need to check a return code.

Constructors
       The actual objects are in the 'Dir' and 'File' sub-namespaces.

   dir
	 my $dir = File::Fu->dir($path);

       See "new" in File::Fu::Dir

   file
	 my $file = File::Fu->file($path);

       See "new" in File::Fu::File

Class Constants
   tmp
       Your system's '/tmp/' directory (or equivalent of that.)

	 my $dir = File::Fu->tmp;

   home
       User's $HOME directory.

	 my $dir = File::Fu->home;

   program_name
       The absolute name of your program.  This will be relative from the time File::Fu was loaded.  It dies if the name is '-e'.

	 my $prog = File::Fu->program_name;

       If File::Fu was loaded after a chdir and the $0 was relative, calling program_name() throws an error.  (Unless you set $0 correctly before
       requiring File::Fu.)

   program_dir
       Returns what typically corresponds to program_name()->dirname, but just the compile-time cwd() when $0 is -e/-E.

	 my $dir = File::Fu->program_dir;

Class Methods
   THIS_FILE
       A nicer way to say __FILE__.

	 my $file = File::Fu->THIS_FILE;

   cwd
       The current working directory.

	 my $dir = File::Fu->cwd;

   which
       Returns File::Fu::File objects of ordered candidates for $name found in the path.

	 my @prog = File::Fu->which($name) or die "cannot find $name";

       If called in scalar context, returns a single File::Fu::File object or throws an error if no candidates were found.

	 my $prog = File::Fu->which($name);

Temporary Directories and Files
       These class methods call the corresponding File::Fu::Dir methods on the value of tmp().	That is, you get a temporary file/dir in the
       '/tmp/' directory.

   temp_dir
	 my $dir = File::Fu->temp_dir;

   temp_file
	 my $handle = File::Fu->temp_file;

Subclassing
       You may wish to subclass File:Fu and override the dir_class() and/or file_class() class methods to point to your own Dir/File subclasses.

	 my $class = 'My::FileFu';
	 my $dir = $class->dir("foo");

       See File::Fu::File and File::Fu::Dir for more info.
