NAME
    File::is - file is older? oldest? is newer? newest? similar? the same?

SYNOPSIS
        use File::is;

        # return if F<file1> is newer than F<file2> or F<file3>.
        return
            if File::is->newer('file1', 'file2', 'file3');

        # do something if F<path1/file1> is older than F<file2> or F<path3/file3>.
        do_some_work()
            if File::is->older([ 'path1', 'file1'], 'file2', [ 'path3', 'file3' ]);

DESCRIPTION
    This module is a result of /me not wanting to write:

        if ($(stat('filename'))[9] < $(stat('tmp/other-filename'))[9]) { do_someting(); };

    Instead I wrote a module with ~80 lines of code and ~90 lines of tests
    for it... So how is the module different from the above `if'? Should be
    reusable, has more functionality, should be clear from the code it self
    what the condition is doing and was fun to play with it. Another
    advantage is that the file names can be passed as array refs. In this
    case File::Spec is used to construct the filename. The resulting code
    is:

        if (File::is->older('filename', [ 'tmp', 'other-filename' ])) { do_something(); };

FUNCTIONS
  newer($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' is newer (has modification
    time-stamp recent) then any of the rest passed as argument.

  newest($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' is newest (has the biggest
    modification time-stamp) compared to the rest of the passed filenames.

  older($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' is older (has the later
    modification time-stamp) then any of the rest passed as argument.

  oldest($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' is oldest (has the latest
    modification time-stamp) compared to the rest of the passed filenames.

  similar($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' has the same size and
    modification time-stamp than any of the rest of the passed filenames.

  thesame($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' has the same inode and dev
    (is hard link) to any of the rest of the passed filenames.

    NOTE: see http://perlmonks.org/?node_id=859612, File::Same

  bigger($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' is bigger (has the bigger
    size) then any of the rest passed as argument.

  biggest($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' is biggest (has the
    biggest size) compared to the rest of the passed filenames.

  smaller($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' is smaller (has the
    smaller size) then any of the rest passed as argument.

  smallest($primary_filename, $other_filename, $other_filename2, ...)
    Returns true/false if the `$primary_filename' is smallest (has the
    smallest size) compared to the rest of the passed filenames.

INTERNALS
    Call/use at your own risk ;-)

  _construct_filename()
    Accepts one or more arguments. It passes them to
    `<File::Spec-'catfile()>> dereferencing the array if one argument array
    ref is passed.

    Example:

        _construct_filename('file')               => 'file'
        _construct_filename([ 'folder', 'file' ]) => File::Spec->catfile('folder', 'file');
        _construct_filename('folder', 'file')     => File::Spec->catfile('folder', 'file');

    This function is called on every argument passed to cmp methods (newer,
    smaller, older, ...).

  _cmp_stat($class, $return_value_if_match, $cmp_function, $primary_filename, $other_filename, $other_filename2, ...)
    This function is called by all of the public `newer()', `smaller()',
    `older()', ... methods do loop through files and do some cmp on them.
