- * SECTION:gapplicationcommandline
- * @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.

- * "This text is written back\n"
- * "to stdout of the caller\n");

- * The complete example can be found here:
- * [gapplication-example-cmdline.c](https://git.gnome.org/browse/glib/tree/gio/tests/gapplication-example-cmdline.c)
- *
- * In more complicated cases, the handling of the comandline can be
- * split between the launcher and the primary instance.

- * In this example of split commandline handling, options that start
- * with `--local-` are handled locally, all other options are passed
- * to the #GApplication::command-line handler which runs in the primary
- * instance.
- *
- * The complete example can be found here:
- * [gapplication-example-cmdline2.c](https://git.gnome.org/browse/glib/tree/gio/tests/gapplication-example-cmdline2.c)

- * If handling the commandline requires a lot of work, it may
- * be better to defer it.

- * In this example the commandline is not completely handled before
- * the #GApplication::command-line handler returns. Instead, we keep
- * a reference to the #GApplicationCommandLine object and handle it
- * later (in this example, in an idle). Note that it is necessary to
- * hold the application until you are done with the commandline.
