If we have an input parameter (or return value) we need to use (nullable). However, if it is an (inout) or (out) parameter, (optional) is sufficient. It looks like (nullable) could be used for everything according to the Annotation documentation, but (optional) is more specific.

|
|
* @title: GApplicationCommandLine
|
|
* @short_description: A command-line invocation of an application
|
|
* @include: gio/gio.h
|
|
* @see_also: #GApplication
|
|
*
|
|
* #GApplicationCommandLine represents a command-line invocation of
|
|
* an application. It is created by #GApplication and emitted
|
|
* in the #GApplication::command-line signal and virtual function.
|
|
*
|
|
* The class contains the list of arguments that the program was invoked
|
|
* with. It is also possible to query if the commandline invocation was
|
|
* local (ie: the current process is running in direct response to the
|
|
* invocation) or remote (ie: some other process forwarded the
|
|
* commandline to this process).
|
|
*
|
|
* The GApplicationCommandLine object can provide the @argc and @argv
|
|
* parameters for use with the #GOptionContext command-line parsing API,
|
|
* with the g_application_command_line_get_arguments() function. See
|
|
* [gapplication-example-cmdline3.c][gapplication-example-cmdline3]
|
|
* for an example.
|
|
*
|
|
* The exit status of the originally-invoked process may be set and
|
|
* messages can be printed to stdout or stderr of that process. The
|
|
* lifecycle of the originally-invoked process is tied to the lifecycle
|
|
* of this object (ie: the process exits when the last reference is
|
|
* dropped).
|
|
*
|
|
* The main use for #GApplicationCommandLine (and the
|
|
* #GApplication::command-line signal) is 'Emacs server' like use cases:
|
|
* You can set the `EDITOR` environment variable to have e.g. git use
|
|
* your favourite editor to edit commit messages, and if you already
|
|
* have an instance of the editor running, the editing will happen
|
|
* in the running instance, instead of opening a new one. An important
|
|
* aspect of this use case is that the process that gets started by git
|
|
* does not return until the editing is done.
|
|
*
|
|
* Normally, the commandline is completely handled in the
|
|
* #GApplication::command-line handler. The launching instance exits
|
|
* once the signal handler in the primary instance has returned, and
|
|
* the return value of the signal handler becomes the exit status
|
|
* of the launching instance.
