NAME
File::BaseDir - Use the Freedesktop.org base directory specification
VERSION
version 0.09
SYNOPSIS
use File::BaseDir qw/xdg_data_files/;
for ( xdg_data_files('mime/globs') ) {
# do something
}
DESCRIPTION
This module can be used to find directories and files as specified by
the Freedesktop.org Base Directory Specification. This specifications
gives a mechanism to locate directories for configuration, application
data and cache data. It is suggested that desktop applications for e.g.
the GNOME, KDE or Xfce platforms follow this layout. However, the same
layout can just as well be used for non-GUI applications.
This module forked from File::MimeInfo.
This module follows version 0.6 of BaseDir specification.
CONSTRUCTOR
new
my $bd = File::BaseDir->new;
Simple constructor to allow calling functions as object oriented
methods.
FUNCTIONS
None of these are exported by default, but all functions can be
exported by request. Also the groups :lookup and :vars are defined. The
:vars group contains all the routines with a xdg_ prefix. The :lookup
group contains the routines to locate files and directories.
data_home
my $path = data_home(@path);
my $path = $bd->data_home(@path);
Takes a list of file path elements and returns a new path by appending
them to the data home directory. The new path does not need to exist.
Use this when writing user specific application data.
Example:
# data_home is: /home/USER/.local/share
$path = $bd->data_home('Foo', 'Bar', 'Baz');
# returns: /home/USER/.local/share/Foo/Bar/Baz
data_dirs
# :lookup
my $dir = data_dirs(@path);
my $dir = $bd->data_dirs(@path);
my @dirs = data_dirs(@path);
my @dirs = $bd->data_dirs(@path);
Looks for directories specified by @path in the data home and other
data directories. Returns (possibly empty) list of readable
directories. In scalar context only the first directory found is
returned. Use this to lookup application data.
data_files
# :lookup
my $file = data_files(@path);
my $file = $bd->data_files(@path);
my @files = data_files(@path);
my @files = $bd->data_files(@path);
Looks for files specified by @path in the data home and other data
directories. Only returns files that are readable. In scalar context
only the first file found is returned. Use this to lookup application
data.
config_home
# :lookup
my $dir = config_home(@path);
my $dir = $bd->config_home(@path);
Takes a list of path elements and appends them to the config home
directory returning a new path. The new path does not need to exist.
Use this when writing user specific configuration.
config_dirs
# :lookup
my $dir = config_dirs(@path);
my $dir = $bd->config_dirs(@path);
my @dirs = config_dirs(@path);
my @dirs = $bd->config_dirs(@path);
Looks for directories specified by @path in the config home and other
config directories. Returns (possibly empty) list of readable
directories. In scalar context only the first directory found is
returned. Use this to lookup configuration.
config_files
# :lookup
my $file = config_files(@path);
my $file = $bd->config_files(@path);
my @files = config_files(@path);
my @files = $bd->config_files(@path);
Looks for files specified by @path in the config home and other config
directories. Returns a (possibly empty) list of files that are
readable. In scalar context only the first file found is returned. Use
this to lookup configuration.
cache_home
# :lookup
my $dir = cache_home(@path);
my $dir = $bd->cache_home(@path);
Takes a list of path elements and appends them to the cache home
directory returning a new path. The new path does not need to exist.
xdg_data_home
# :var
my $dir = xdg_data_home;
my $dir = $bd->xdg_data_home;
Returns either $ENV{XDG_DATA_HOME} or it's default value. Default is
$HOME/.local/share.
xdg_data_dirs
# :var
my @dirs = xdg_data_dirs;
my @dirs = $bd->xdg_data_dirs;
Returns either $ENV{XDG_DATA_DIRS} or it's default value as list.
Default is /usr/local/share, /usr/share.
xdg_config_home
# :var
my $dir = xdg_config_home;
my $dir = $bd->xdg_config_home;
Returns either $ENV{XDG_CONFIG_HOME} or it's default value. Default is
$HOME/.config.
xdg_config_dirs
# :var
my @dirs = xdg_config_dirs;
my @dirs = $bd->xdg_config_dirs;
Returns either $ENV{XDG_CONFIG_DIRS} or it's default value as list.
Default is /etc/xdg.
xdg_cache_home
# :var
my $dir = xdg_cache_home;
my $dir = $bd->xdg_cache_home;
Returns either $ENV{XDG_CACHE_HOME} or it's default value. Default is
$HOME/.cache.
NON-UNIX PLATFORMS
The use of File::Spec ensures that all paths are returned in their
native formats regardless of platform. On Windows this module will use
the native environment variables, rather than the default on UNIX
(which is traditionally $HOME).
Please note that the specification is targeting Unix platforms only and
will only have limited relevance on other platforms. Any platform
dependent behavior in this module should be considered an extension of
the spec.
BACKWARDS COMPATIBILITY
The methods xdg_data_files() and xdg_config_files() are exported for
backwards compatibility with version 0.02. They are identical to
data_files() and config_files() respectively but without the wantarray
behavior.
