       File::DesktopEntry - Object to handle .desktop files

	       use File::DesktopEntry;

	       my $entry = File::DesktopEntry->new('firefox');

	       print "Using ".$entry->Name." to open\n";

       This module is used to work with .desktop files. The format of these
       files is specified by the freedesktop "Desktop Entry" specification.
       This module can parse these files but also knows how to run the
       applications defined by these files.

       For this module version 1.0 of the specification was used.

       This module was written to support File::MimeInfo::Applications.

       Please remember: case is significant for the names of Desktop Entry

       You can set the global variable $File::DesktopEntry::VERBOSE. If set
       the module print a warning every time a command gets executed.

       The global variable $File::DesktopEntry::LOCALE tells you what the
       default locale being used is. However, changing it will not change the
       default locale.

       All methods that start with a capital are autoloaded as "get(KEY)"
       where key is the autoloaded method name.

	   Constructor. FILE, NAME or TEXT are optional arguments.

	   When a name is given (a string without '"/"', '"\"' or '"."') a
	   lookup is done using File::BaseDir. If the file found in this
	   lookup is not writable or if no file was found, the XDG_DATA_HOME
	   path will be used when writing.

	   Returns a filename for a desktop entry with desktop file id NAME.

       "wants_uris( )"
	   Returns true if the Exec string for this desktop entry specifies
	   that the application uses URIs instead of paths. This can be used
	   to determine whether an application uses a VFS library.

       "wants_list( )"
	   Returns true if the Exec string for this desktop entry specifies
	   that the application can handle multiple arguments at once.

	   Forks and runs the application specified in this Desktop Entry with
	   arguments FILES as a background process. Returns the pid.

	   The child process fails when this is not a Desktop Entry of type
	   Application or if the Exec key is missing or invalid.

	   If the desktop entry specifies that the program needs to be
	   executed in a terminal the $TERMINAL environment variable is used.
	   If this variable is not set "xterm -e" is used as default.

	   (On Windows this method returns a Win32::Process object.)

	   Like "run()" but using the "system()" system call.  It only return
	   after the application has ended.

	   Like "run()" but using the "exec()" system call. This method is
	   expected not to return but to replace the current process with the
	   application you try to run.

	   On Windows this method doesn't always work the way you want it to
	   due to the "fork()" emulation on this platform. Try using "run()"
	   or "system()" instead.

	   Expands the Exec format in this desktop entry with. Returns a
	   properly quoted string in scalar context or a list of words in list
	   context. Dies when the Exec key is invalid.

	   It supports the following fields:

		   %f	   single file
		   %F	   multiple files
		   %u	   single url
		   %U	   multiple urls
		   %i	   Icon field prefixed by --icon
		   %c	   Name field, possibly translated
		   %k	   location of this .desktop file
		   %%	   literal '%'

	   If necessary this method tries to convert between paths and URLs
	   but this is not perfect.

	   Fields that are deprecated, but (still) supported by this module:

		   %d	   single directory
		   %D	   multiple directories

	   The fields %n, %N, %v and %m are deprecated and will cause a
	   warning if $VERBOSE is used. Any other unknown fields will cause an

	   The fields %F, %U, %D and %i can only occur as separate words
	   because they expand to multiple arguments.

	   Also see "LIMITATIONS".

       "get(GROUP, KEY)"
	   Get a value for KEY from GROUP. If GROUP is not specified 'Desktop
	   Entry' is used. All values are treated as string, so e.g. booleans
	   will be returned as the literal strings "true" and "false".

	   When KEY does not contain a language code you get the translation
	   in the current locale if available or a sensible default. The
	   request a specific language you can add the language part. E.g.
	   "$entry->get('Name[nl_NL]')" can return either the value of the
	   'Name[nl_NL]', the 'Name[nl]' or the 'Name' key in the Desktop
	   Entry file. Exact language parsing order can be found in the spec.
	   To force you get the untranslated key use either 'Name[C]' or

       "set(KEY => VALUE, ...)"
       "set(GROUP, KEY => VALUE, ...)"
	   Set values for one or more keys. If GROUP is not given "Desktop
	   Entry" is used.  All values are treated as strings, backslashes,
	   newlines and tabs are escaped.  To set a boolean key you need to
	   use the literal strings "true" and "false".

	   Unlike the "get()" call languages are not handled automatically for
	   "set()".  KEY should include the language part if you want to set a
	   translation.	 E.g. "$entry->set("Name[nl_NL]" => "Tekst
	   Verwerker")" will set a Dutch translation for the Name key. Using
	   either "Name[C]" or "Name[POSIX]" will be equivalent with not
	   giving a language argument.

	   When setting the Exec key without specifying a group it will be
	   parsed and quoted correctly as required by the spec. You can use
	   quoted arguments to include whitespace in a argument, escaping
	   whitespace does not work.  To circumvent this quoting explicitly
	   give the group name 'Desktop Entry'.

	   Returns the (modified) text of the file.

	   Read Desktop Entry data from file or memory buffer.	Without
	   argument defaults to file given at constructor.

	   If you gave a file, text buffer or name to the constructor this
	   method will be called automatically.

	   Read Desktop Entry data from filehandle or IO object.

	   Write the Desktop Entry data to FILE. Without arguments it writes
	   to the filename given to the constructor if any.

	   The keys Name and Type are required. Type can be either
	   "Application", "Link" or "Directory". For an application set the
	   optional key "Exec". For a link set the "URL" key.

   Backwards Compatibility
       Methods supported for backwards compatibility with 0.02.

	   Alias for "new(FILE)".

	   Alias for "new(\$TEXT)".

       "get_value(NAME, GROUP, LANG)"
	   Identical to "get(GROUP, "NAME[LANG]")".  LANG defaults to 'C',
	   GROUP is optional.

       This module has a few bit of code to make it save on Windows. It
       handles "file://" uri a bit different and it uses Win32::Process. On
       other platforms your mileage may vary.

       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.

       If you try to exec a remote file with an application that can only
       handle files on the local file system we should -according to the spec-
       download the file to a temp location. This is not supported. Use the
       "wants_uris()" method to check if an application supports urls.

       The values of the various Desktop Entry keys are not parsed (except for
       the Exec key). This means that booleans will be returned as the strings
       "true" and "false" and lists will still be ";" separated.

       If the icon is given as name and not as path it should be resolved for
       the %i code in the Exec key. We need a separate module for the icon
       spec to deal with this.

       Files are read and written using utf8, this is not available on perl
       versions before 5.8. As a result for older perl versions translations
       in UTF-8 will not be translated properly.

       According to the spec comments can contain any encoding. However since
       this module read files as utf8, invalid UTF-8 characters in a comment
       will cause an error.

       There is no support for Legacy-Mixed Encoding. Everybody is using utf8
       now ... right ?
