=head1 NAME
Mojo::File - File system paths
=head1 SYNOPSIS
use Mojo::File;
# Portably deal with file system paths
my $path = Mojo::File->new('/home/sri/.vimrc');
say $path->slurp;
say $path->basename;
say $path->dirname->child('.bashrc');
# Use the alternative constructor
use Mojo::File 'path';
my $path = path('/tmp/foo/bar')->make_path;
$path->child('test.txt')->spurt('Hello Mojo!');
=head1 DESCRIPTION
L<Mojo::File> is a scalar-based container for file system paths that provides a
friendly API for dealing with different operating systems.
# Access scalar directly to manipulate path
my $path = Mojo::File->new('/home/sri/test');
$$path .= '.txt';
=head1 FUNCTIONS
L<Mojo::File> implements the following functions, which can be imported
individually.
=head2 path
my $path = path;
my $path = path('/home/sri/.vimrc');
my $path = path('/home', 'sri', '.vimrc');
my $path = path(File::Temp->newdir);
Construct a new scalar-based L<Mojo::File> object, defaults to using the current
working directory.
# "foo/bar/baz.txt" (on UNIX)
path('foo', 'bar', 'baz.txt');
=head2 tempdir
my $path = tempdir;
my $path = tempdir('tempXXXXX');
Construct a new scalar-based L<Mojo::File> object for a temporary directory with
L<File::Temp>.
# Longer version
my $path = Mojo::File->new(File::Temp->newdir('tempXXXXX'));
=head1 METHODS
L<Mojo::File> implements the following methods.
=head2 basename
my $name = $path->basename;
my $name = $path->basename('.txt');
Return the last level of the path with L<File::Basename>.
# ".vimrc" (on UNIX)
Mojo::File->new('/home/sri/.vimrc')->basename;
# "test" (on UNIX)
Mojo::File->new('/home/sri/test.txt')->basename('.txt');
=head2 child
my $child = $path->child('.vimrc');
Return a new L<Mojo::File> object relative to the path.
# "/home/sri/.vimrc" (on UNIX)
Mojo::File->new('/home')->child('sri', '.vimrc');
=head2 dirname
my $name = $path->dirname;
Return all but the last level of the path with L<File::Basename> as a
L<Mojo::File> object.
# "/home/sri" (on UNIX)
Mojo::File->new('/home/sri/.vimrc')->dirname;
=head2 is_abs
my $bool = $path->is_abs;
Check if the path is absolute.
# True (on UNIX)
Mojo::File->new('/home/sri/.vimrc')->is_abs;
# False (on UNIX)
Mojo::File->new('.vimrc')->is_abs;
=head2 list
my $collection = $path->list;
my $collection = $path->list({hidden => 1});
List all files in the directory and return a L<Mojo::Collection> object
containing the results as L<Mojo::File> objects.
# List files
say for Mojo::File->new('/home/sri/myapp')->list->each;
These options are currently available:
=over 2
=item dir
dir => 1
Include directories.
=item hidden
hidden => 1
Include hidden files.
=back
=head2 list_tree
my $collection = $path->list_tree;
my $collection = $path->list_tree({hidden => 1});
List all files recursively in the directory and return a L<Mojo::Collection>
object containing the results as L<Mojo::File> objects.
# List all templates
say for Mojo::File->new('/home/sri/myapp/templates')->list_tree->each;
These options are currently available:
=over 2
=item hidden
hidden => 1
Include hidden files and directories.
=back
=head2 make_path
$path = $path->make_path;
Create the directories if they don't already exist with L<File::Path>.
=head2 move_to
$path = $path->move_to('/home/sri/.vimrc.backup');
Move the file.
=head2 new
my $path = Mojo::File->new;
my $path = Mojo::File->new('/home/sri/.vimrc');
my $path = Mojo::File->new('/home', 'sri', '.vimrc');
my $path = Mojo::File->new(File::Temp->newdir);
Construct a new L<Mojo::File> object, defaults to using the current working
directory.
# "foo/bar/baz.txt" (on UNIX)
Mojo::File->new('foo', 'bar', 'baz.txt');
=head2 slurp
my $bytes = $path->slurp;
Read all data at once from the file.
=head2 spurt
$path = $path->spurt($bytes);
Write all data at once to the file.
=head2 tap
$path = $path->tap(sub {...});
Alias for L<Mojo::Base/"tap">.
=head2 to_abs
my $absolute = $path->to_abs;
Return the canonical path as a L<Mojo::File> object.
=head2 to_array
my $parts = $path->to_array;
Split the path on directory separators.
# "home:sri:.vimrc" (on UNIX)
join ':', @{Mojo::File->new('/home/sri/.vimrc')->to_array};
=head2 to_rel
my $relative = $path->to_rel('/some/base/path');
Return a relative path from the original path to the destination path as a
L<Mojo::File> object.
# "sri/.vimrc" (on UNIX)
Mojo::File->new('/home/sri/.vimrc')->to_rel('/home');
=head2 to_string
my $str = $path->to_string;
Stringify the path.
=head1 OPERATORS
L<Mojo::File> overloads the following operators.
=head2 array
my @parts = @$path;
Alias for L</"to_array">.
=head2 bool
my $bool = !!$path;
Always true.
=head2 stringify
my $str = "$path";
Alias for L</"to_string">.
