NAME

File::XDG - Basic implementation of the XDG base directory specification

VERSION

version 0.08

SYNOPSIS

 use File::XDG;

 my $xdg = File::XDG->new(name => 'foo');

 # user config
 my $path = $xdg->config_home;

 # user data
 my $path = $xdg->data_home;

 # user cache
 my $path = $xdg->cache_home;

 # system config
 my @dirs = $xdg->config_dirs_list;

 # system data
 my @dirs = $xdg->data_dirs_list;

DESCRIPTION

This module provides a basic implementation of the XDG base directory specification as exists by the Free Desktop Organization (FDO). It supports all XDG directories except for the runtime directories, which require session management support in order to function.

CONSTRUCTOR

new

 my $xdg = File::XDG->new( %args );

Returns a new instance of a File::XDG object. This must be called with an application name as the "name" argument.

Takes the following named arguments:

name

Name of the application for which File::XDG is being used.

METHODS

data_home

 my $path = $xdg->data_home;

Returns the user-specific data directory for the application as a Path::Class object.

config_home

 my $path = $xdg->config_home;

Returns the user-specific configuration directory for the application as a Path::Class object.

cache_home

 my $path = $xdg->cache_home;

Returns the user-specific cache directory for the application as a Path::Class object.

data_dirs

 my $dirs = $xdg->data_dirs;

Returns the system data directories, not modified for the application. Per the specification, the returned string is :-delimited, except on Windows where it is ;-delimited.

For portability "data_dirs_list" is preferred.

data_dirs_list

[version 0.06]

 my @dirs = $xdg->data_dirs_list;

Returns the system data directories as a list of Path::Class objects.

config_dirs

 my $dirs = $xdg->config_dirs;

Returns the system config directories, not modified for the application. Per the specification, the returned string is :-delimited, except on Windows where it is ;-delimited.

For portability "config_dirs_list" is preferred.

config_dirs_list

[version 0.06]

 my @dirs = $xdg->config_dirs_list;

Returns the system config directories as a list of Path::Class objects.

lookup_data_file

 my $path = $xdg->lookup_data_file($subdir, $filename);

Looks up the data file by searching for ./$subdir/$filename relative to all base directories indicated by $XDG_DATA_HOME and $XDG_DATA_DIRS. If an environment variable is either not set or empty, its default value as defined by the specification is used instead. Returns a Path::Class object.

lookup_config_file

 my $path = $xdg->lookup_config_file($subdir, $filename);

Looks up the configuration file by searching for ./$subdir/$filename relative to all base directories indicated by $XDG_CONFIG_HOME and $XDG_CONFIG_DIRS. If an environment variable is either not set or empty, its default value as defined by the specification is used instead. Returns a Path::Class object.

CAVEATS

This module intentionally and out of necessity does not follow the spec on the following platforms:

MSWin32 (Strawberry Perl, Visual C++ Perl, etc)

The spec requires : as the path separator, but use of this character is essential for absolute path names in Windows, so the Windows Path separator ; is used instead.

There are no global data or config directories in windows so the data and config directories are empty list instead of the default UNIX locations.

The base directory instead of being the user's home directory is %LOCALAPPDATA%. Arguably the data and config base directory should be %APPDATA%, but cache should definitely be in %LOCALAPPDATA%, and we chose to use just one base directory for simplicity.

SEE ALSO

Path::Class

Portable native path class used by this module.

Path::Spec

Core Perl library for working with file and directory paths.

File::BaseDir

Provides similar functionality to this module with a different interface.
