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;

  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!

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

list

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

  dir => 1

list_tree

  my $collection = $path->list_tree;

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

These options are currently available:

  dir => 1
    

Include directories.

  dont_use_nlink => 1

Include hidden files and directories.

  max_depth => 3
    

Maximum number of levels to descend when searching for files.
