NAME

Mojo::File - File system paths

SYNOPSIS

use Mojo::File;

# Portably deal with file system paths
my $path = Mojo::File->new('/home/sri/.vimrc');
say $path->slurp;
say $path->dirname;
say $path->basename;
say $path->extname;
say $path->sibling('.bashrc');

# Use the alternative constructor
use Mojo::File qw(path);
my $path = path('/tmp/foo/bar')->make_path;
$path->child('test.txt')->spew('Hello Mojo!');

DESCRIPTION

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';

FUNCTIONS

Mojo::File implements the following functions, which can be imported individually.

curfile

my $path = curfile;

Construct a new scalar-based Mojo::File object for the absolute path to the current source file.

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 Mojo::File object, defaults to using the current working directory.

# "foo/bar/baz.txt" (on UNIX)
path('foo', 'bar', 'baz.txt');

tempdir

my $path = tempdir;
my $path = tempdir('tempXXXXX');

Construct a new scalar-based Mojo::File object for a temporary directory with File::Temp.

# Longer version
my $path = path(File::Temp->newdir('tempXXXXX'));

tempfile

my $path = tempfile;
my $path = tempfile(DIR => '/tmp');

Construct a new scalar-based Mojo::File object for a temporary file with File::Temp.

# Longer version
my $path = path(File::Temp->new(DIR => '/tmp'));

METHODS

Mojo::File implements the following methods.

basename

my $name = $path->basename;
my $name = $path->basename('.txt');

Return the last level of the path with File::Basename.

# ".vimrc" (on UNIX)
path('/home/sri/.vimrc')->basename;

# "test" (on UNIX)
path('/home/sri/test.txt')->basename('.txt');

child

my $child = $path->child('.vimrc');

Return a new Mojo::File object relative to the path.

# "/home/sri/.vimrc" (on UNIX)
path('/home')->child('sri', '.vimrc');

chmod

$path = $path->chmod(0644);

Change file permissions.

copy_to

my $destination = $path->copy_to('/home/sri');
my $destination = $path->copy_to('/home/sri/.vimrc.backup');

Copy file with File::Copy and return the destination as a Mojo::File object.

dirname

my $name = $path->dirname;

Return all but the last level of the path with File::Basename as a Mojo::File object.

# "/home/sri" (on UNIX)
path('/home/sri/.vimrc')->dirname;

download

my $bool = $path->download('https://example.com/test.tar.gz');
my $bool = $path->download('https://example.com/test.tar.gz', {headers => {Accept => '*/*'}});
my $bool = $path->download('https://example.com/test.tar.gz', {ua => Mojo::UserAgent->new});

Download file from URL, returns true once the file has been downloaded completely. Incomplete downloads are resumed. Follows 10 redirects by default and does not limit the size of the response, which will be streamed memory efficiently. Note that this method is EXPERIMENTAL and might change without warning!

extname

my $ext = $path->extname;

Return file extension of the path.

# "js"
path('/home/sri/test.js')->extname;

is_abs

my $bool = $path->is_abs;

Check if the path is absolute.

# True (on UNIX)
path('/home/sri/.vimrc')->is_abs;

# False (on UNIX)
path('.vimrc')->is_abs;

list

my $collection = $path->list;
my $collection = $path->list({hidden => 1});

List all files in the directory and return a Mojo::Collection object containing the results as Mojo::File objects. The list does not include . and ...

# List files
say for path('/home/sri/myapp')->list->each;

These options are currently available:

dir
dir => 1

Include directories.

hidden
hidden => 1

Include hidden files.

list_tree

my $collection = $path->list_tree;
my $collection = $path->list_tree({hidden => 1});

List all files recursively in the directory and return a Mojo::Collection object containing the results as Mojo::File objects. The list does not include . and ...

# List all templates
say for path('/home/sri/myapp/templates')->list_tree->each;

These options are currently available:

dir
dir => 1

Include directories.

dont_use_nlink => 1

Force File::Find to always stat directories.

hidden
hidden => 1

Include hidden files and directories.

max_depth
max_depth => 3

lstat

my $stat = $path->lstat;

Return a File::stat object for the symlink.
