This continues the changes done in https://bugzilla.gnome.org/show_bug.cgi?id=767245 This makes it possible to pass Python path types as process arguments and env vars in PyGObject and and makes it clear that the values are not strictly utf-8 and need to be validated/converted first. https://bugzilla.gnome.org/show_bug.cgi?id=788863

|
|
* @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.
