Mojo::File(3)

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!
