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.
|lookup(NAME)||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.)
|system(@FILES)||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 doesnt 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:
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:
The fields %F, %U, %D and %i can only occur as separate words because they expand to multiple arguments.
Also see LIMITATIONS.
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 Name[POSIX].
|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.
|text()||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_fh(IO)||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.
Methods supported for backwards compatibility with 0.02.
new_from_file(FILE) Alias for new(FILE). new_from_data(TEXT) 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.
There is no support for Legacy-Mixed Encoding. Everybody is using utf8 now ... right ?
