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->sibling('.bashrc');

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

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');

child

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

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

  path('/home')->child('sri', '.vimrc');

chmod

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

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;

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

hidden

  hidden => 1

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

  dont_use_nlink => 1

Force File::Find to always stat directories.

hidden

  hidden => 1

Include hidden files and directories.

max_depth

  max_depth => 3

Maximum number of levels to descend when searching for files.

lstat

  my $stat = $path->lstat;
