DESCRIPTION
    File::HomeDir is a module for locating the directories that are "owned"
    by a user (typicaly your user) and to solve the various issues that
    arise trying to find them consistently across a wide variety of
    platforms.

    The end result is a single API that can find your resources on any
    platform, making it relatively trivial to create Perl software that
    works elegantly and correctly no matter where you run it.

    This module provides two main interfaces.

    The first is a modern File::Spec-style interface with a consistent OO
    API and different implementation modules to support various platforms.
    You are strongly recommended to use this interface.

    The second interface is for legacy support of the original 0.07
    interface that exported a "home()" function by default and tied the "%~"
    variable.

    It is generally not recommended that you use this interface, but due to
    back-compatibility reasons they will remain supported until at least
    2010.

    The "%~" interface has been deprecated. Documentation was removed in
    2009, Unit test were removed in 2011, usage will issue warnings from
    2012, and the interface will be removed entirely in 2015 (in line with
    the general Perl toolchain convention of a 10 year support period for
    legacy APIs that are potentially or actually in common use).

  Platform Neutrality
    In the Unix world, many different types of data can be mixed together in
    your home directory (although on some Unix platforms this is no longer
    the case, particularly for "desktop"-oriented platforms).

    On some non-Unix platforms, separate directories are allocated for
    different types of data and have been for a long time.

    When writing applications on top of File::HomeDir, you should thus
    always try to use the most specific method you can. User documents
    should be saved in "my_documents", data that supports an application but
    isn't normally editing by the user directory should go into "my_data".

    On platforms that do not make any distinction, all these different
    methods will harmlessly degrade to the main home directory, but on
    platforms that care File::HomeDir will always try to Do The Right
    Thing(tm).

METHODS
    Two types of methods are provided. The "my_method" series of methods for
    finding resources for the current user, and the "users_method" (read as
    "user's method") series for finding resources for arbitrary users.

    This split is necessary, as on most platforms it is much easier to find
    information about the current user compared to other users, and indeed
    on a number you cannot find out information such as "users_desktop" at
    all, due to security restrictions.

    All methods will double check (using a "-d" test) that a directory
    actually exists before returning it, so you may trust in the values that
    are returned (subject to the usual caveats of race conditions of
    directories being deleted at the moment between a directory being
    returned and you using it).

    However, because in some cases platforms may not support the concept of
    home directories at all, any method may return "undef" (both in scalar
    and list context) to indicate that there is no matching directory on the
    system.

    For example, most untrusted 'nobody'-type users do not have a home
    directory. So any modules that are used in a CGI application that at
    some level of recursion use your code, will result in calls to
    File::HomeDir returning undef, even for a basic home() call.

  my_home
    The "my_home" method takes no arguments and returns the main
    home/profile directory for the current user.

    If the distinction is important to you, the term "current" refers to the
    real user, and not the effective user.

    This is also the case for all of the other "my" methods.

    Returns the directory path as a string, "undef" if the current user does
    not have a home directory, or dies on error.

  my_desktop
    The "my_desktop" method takes no arguments and returns the "desktop"
    directory for the current user.

    Due to the diversity and complexity of implementions required to deal
    with implementing the required functionality fully and completely, the
    "my_desktop" method may or may not be implemented on each platform.

    That said, I am extremely interested in code to implement "my_desktop"
    on Unix, as long as it is capable of dealing (as the Windows
    implementation does) with internationalisation. It should also avoid
    false positive results by making sure it only returns the appropriate
    directories for the appropriate platforms.

    Returns the directory path as a string, "undef" if the current user does
    not have a desktop directory, or dies on error.

  my_documents
    The "my_documents" method takes no arguments and returns the directory
    (for the current user) where the user's documents are stored.

    Returns the directory path as a string, "undef" if the current user does
    not have a documents directory, or dies on error.

  my_music
    The "my_music" method takes no arguments and returns the directory where
    the current user's music is stored.

    No bias is made to any particular music type or music program, rather
    the concept of a directory to hold the user's music is made at the level
    of the underlying operating system or (at least) desktop environment.

    Returns the directory path as a string, "undef" if the current user does
    not have a suitable directory, or dies on error.

  my_pictures
    The "my_pictures" method takes no arguments and returns the directory
    where the current user's pictures are stored.

    No bias is made to any particular picture type or picture program,
    rather the concept of a directory to hold the user's pictures is made at
    the level of the underlying operating system or (at least) desktop
    environment.

    Returns the directory path as a string, "undef" if the current user does
    not have a suitable directory, or dies on error.

  my_videos
    The "my_videos" method takes no arguments and returns the directory
    where the current user's videos are stored.

    No bias is made to any particular video type or video program, rather
    the concept of a directory to hold the user's videos is made at the
    level of the underlying operating system or (at least) desktop
    environment.

    Returns the directory path as a string, "undef" if the current user does
    not have a suitable directory, or dies on error.

  my_data
    The "my_data" method takes no arguments and returns the directory where
    local applications should stored their internal data for the current
    user.

    Generally an application would create a subdirectory such as ".foo",
    beneath this directory, and store its data there. By creating your
    directory this way, you get an accurate result on the maximum number of
    platforms. But see the documentation about "my_dist_config()" or
    "my_dist_data()" below.

    For example, on Unix you get "~/.foo" and on Win32 you get "~/Local
    Settings/Application Data/.foo"

    Returns the directory path as a string, "undef" if the current user does
    not have a data directory, or dies on error.

  my_dist_config
      File::HomeDir-&gt;my_dist_config( $dist [, \%params] );
      
  # For example...
      
  File::HomeDir-&gt;my_dist_config( 'File-HomeDir' );
      File::HomeDir-&gt;my_dist_config( 'File-HomeDir', { create =&gt; 1 } );

    The "my_dist_config" method takes a distribution name as argument and
    returns an application-specific directory where they should store their
    internal configuration.

    The base directory will be either "my_config" if the platform supports
    it, or "my_documents" otherwise. The subdirectory itself will be
    "BASE/Perl/Dist-Name". If the base directory is the user's homedir,
    "my_dist_config" will be in "~/.perl/Dist-Name" (and thus be hidden on
    all Unixes).

    The optional last argument is a hash reference to tweak the method
    behaviour. The following hash keys are recognized:

    *   create

        Passing a true value to this key will force the creation of the
        directory if it doesn't exist (remember that "File::HomeDir"'s
        policy is to return "undef" if the directory doesn't exist).

        Defaults to false, meaning no automatic creation of directory.

  my_dist_data
      File::HomeDir-&gt;my_dist_data( $dist [, \%params] );
      
  # For example...
      
  File::HomeDir-&gt;my_dist_data( 'File-HomeDir' );
      File::HomeDir-&gt;my_dist_data( 'File-HomeDir', { create =&gt; 1 } );

    The "my_dist_data" method takes a distribution name as argument and
    returns an application-specific directory where they should store their
    internal data.

    This directory will be of course a subdirectory of "my_data". Platforms
    supporting data-specific directories will use
    "DATA_DIR/perl/dist/Dist-Name" following the common
    "DATA/vendor/application" pattern. If the "my_data" directory is the
    user's homedir, "my_dist_data" will be in "~/.perl/dist/Dist-Name" (and
    thus be hidden on all Unixes).

    The optional last argument is a hash reference to tweak the method
    behaviour. The following hash keys are recognized:

    *   create

        Passing a true value to this key will force the creation of the
        directory if it doesn't exist (remember that "File::HomeDir"'s
        policy is to return "undef" if the directory doesn't exist).

        Defaults to false, meaning no automatic creation of directory.

  users_home
      $home = File::HomeDir-&gt;users_home('foo');

    The "users_home" method takes a single param and is used to locate the
    parent home/profile directory for an identified user on the system.

    While most of the time this identifier would be some form of user name,
    it is permitted to vary per-platform to support user ids or UUIDs as
    applicable for that platform.

    Returns the directory path as a string, "undef" if that user does not
    have a home directory, or dies on error.

  users_documents
      $docs = File::HomeDir-&gt;users_documents('foo');

    Returns the directory path as a string, "undef" if that user does not
    have a documents directory, or dies on error.

  users_data
      $data = File::HomeDir-&gt;users_data('foo');

    Returns the directory path as a string, "undef" if that user does not
    have a data directory, or dies on error.

FUNCTIONS
  home
      use File::HomeDir;
      $home = home();
      $home = home('foo');
      $home = File::HomeDir::home();
      $home = File::HomeDir::home('foo');

    The "home" function is exported by default and is provided for
    compatibility with legacy applications. In new applications, you should
    use the newer method-based interface above.

    Returns the directory path to a named user's home/profile directory.

    If provided no param, returns the directory path to the current user's
    home/profile directory.

TO DO
    *   Add more granularity to Unix, and add support to VMS and other
        esoteric platforms, so we can consider going core.

    *   Add consistent support for users_* methods

SUPPORT

    Write access to the repository is made available automatically to any
    published CPAN author, and to most other volunteers on request.

    If you are able to submit your bug report in the form of new (failing)
    unit tests, or can apply your fix directly instead of submitting a
    patch, you are strongly encouraged to do so as the author currently
    maintains over 100 modules and it can take some time to deal with
    non-Critical bug reports or patches.

    This will guarantee that your issue will be addressed in the next
    release of the module.

    If you cannot provide a direct test or fix, or don't have time to do so,
    then regular bug reports are still accepted and appreciated via the CPAN
    bug tracker.

ACKNOWLEDGEMENTS
    The biggest acknowledgement goes to Chris Nandor, who wielded his
    legendary Mac-fu and turned my initial fairly ordinary Darwin
    implementation into something that actually worked properly everywhere,
    and then donated a Mac OS X license to allow it to be maintained
    properly.
