Description
|
|
Packit |
ae235b |
GApplicationCommandLine represents a command-line invocation of
|
|
Packit |
ae235b |
an application. It is created by GApplication and emitted
|
|
Packit |
ae235b |
in the “command-line” signal and virtual function.
|
|
Packit |
ae235b |
The class contains the list of arguments that the program was invoked
|
|
Packit |
ae235b |
with. It is also possible to query if the commandline invocation was
|
|
Packit |
ae235b |
local (ie: the current process is running in direct response to the
|
|
Packit |
ae235b |
invocation) or remote (ie: some other process forwarded the
|
|
Packit |
ae235b |
commandline to this process).
|
|
Packit |
ae235b |
The GApplicationCommandLine object can provide the argc
|
|
Packit |
ae235b |
and argv
|
|
Packit |
ae235b |
|
|
Packit |
ae235b |
parameters for use with the GOptionContext command-line parsing API,
|
|
Packit |
ae235b |
with the g_application_command_line_get_arguments() function. See
|
|
Packit |
ae235b |
gapplication-example-cmdline3.c
|
|
Packit |
ae235b |
for an example.
|
|
Packit |
ae235b |
The exit status of the originally-invoked process may be set and
|
|
Packit |
ae235b |
messages can be printed to stdout or stderr of that process. The
|
|
Packit |
ae235b |
lifecycle of the originally-invoked process is tied to the lifecycle
|
|
Packit |
ae235b |
of this object (ie: the process exits when the last reference is
|
|
Packit |
ae235b |
dropped).
|
|
Packit |
ae235b |
The main use for GApplicationCommandLine (and the
|
|
Packit |
ae235b |
“command-line” signal) is 'Emacs server' like use cases:
|
|
Packit |
ae235b |
You can set the EDITOR environment variable to have e.g. git use
|
|
Packit |
ae235b |
your favourite editor to edit commit messages, and if you already
|
|
Packit |
ae235b |
have an instance of the editor running, the editing will happen
|
|
Packit |
ae235b |
in the running instance, instead of opening a new one. An important
|
|
Packit |
ae235b |
aspect of this use case is that the process that gets started by git
|
|
Packit |
ae235b |
does not return until the editing is done.
|
|
Packit |
ae235b |
Normally, the commandline is completely handled in the
|
|
Packit |
ae235b |
“command-line” handler. The launching instance exits
|
|
Packit |
ae235b |
once the signal handler in the primary instance has returned, and
|
|
Packit |
ae235b |
the return value of the signal handler becomes the exit status
|
|
Packit |
ae235b |
of the launching instance.

In this example of split commandline handling, options that start
|
|
Packit |
ae235b |
with --local- are handled locally, all other options are passed
|
|
Packit |
ae235b |
to the “command-line” handler which runs in the primary
|
|
Packit |
ae235b |
instance.

If handling the commandline requires a lot of work, it may
|
|
Packit |
ae235b |
be better to defer it.

In this example the commandline is not completely handled before
|
|
Packit |
ae235b |
the “command-line” handler returns. Instead, we keep
|
|
Packit |
ae235b |
a reference to the GApplicationCommandLine object and handle it
|
|
Packit |
ae235b |
later (in this example, in an idle). Note that it is necessary to
|
|
Packit |
ae235b |
hold the application until you are done with the commandline.

The strings in the array may contain non-UTF-8 data on UNIX (such as

Packit |

If you wish to use the return value with GOptionContext, you must

use g_option_context_parse_strv().
|
|
Packit |
ae235b |

Packit |

The string may contain non-utf8 data.

ae235b |
invocation, as would be returned by g_get_environ(), ie as a
|
|
Packit |
ae235b |

|
|
Packit |
ae235b |
The strings may contain non-utf8 data.
|
|
Packit |
ae235b |
The remote application usually does not send an environment. Use
|
|
Packit |
ae235b |
G_APPLICATION_SEND_ENVIRONMENT to affect that. Even with this flag
|
|
Packit |
ae235b |
set it is possible that the environment is still not available (due
|
|
Packit |
ae235b |
to invocation messages from other applications).

The return value should not be modified or freed and is valid for as

ae235b |
Gets the options there were passed to g_application_command_line().
|
|
Packit |
ae235b |
If you did not override local_command_line() then these are the same
|

Packit |
ae235b |
options that were parsed according to the GOptionEntrys added to the

Packit |
ae235b |

Packit |
ae235b |
modified from your GApplication::handle-local-options handler.
|

Packit |
ae235b |
If no options were sent then an empty dictionary is returned so that

|
|
Packit |
ae235b |
Gets the stdin of the invoking process.
|
|
Packit |
ae235b |
The GInputStream can be used to read data passed to the standard
|
|
Packit |
ae235b |
input of the invoking process.
|
|
Packit |
ae235b |
This doesn't work on all platforms. Presently, it is only available
|
|
Packit |
ae235b |
on UNIX when using a DBus daemon capable of passing file descriptors.
|
|
Packit |
ae235b |
If stdin is not available then NULL will be returned. In the
|
|
Packit |
ae235b |
future, support may be expanded to other platforms.
|
|
Packit |
ae235b |

line invocation, as would be returned by g_getenv(). The strings may

Packit |
ae235b |

|
|
Packit |
ae235b |
The remote application usually does not send an environment. Use

|
Packit |
ae235b |
G_APPLICATION_SEND_ENVIRONMENT to affect that. Even with this flag
|
|
Packit |
ae235b |
set it is possible that the environment is still not available (due

Packit |
ae235b |
to invocation messages from other applications).

The return value should not be modified or freed and is valid for as

ae235b |
(GApplicationCommandLine *cmdline,
|
|
Packit |
ae235b |
int exit_status);
|
|
Packit |
ae235b |
Sets the exit status that will be used when the invoking process
|
|
Packit |
ae235b |
exits.
|
|
Packit |
ae235b |
The return value of the “command-line” signal is
|
|
Packit |
ae235b |
passed to this function when the handler returns. This is the usual
|
|
Packit |
ae235b |
way of setting the exit status.
|
|
Packit |
ae235b |
In the event that you want the remote invocation to continue running
|
|
Packit |
ae235b |
and want to decide on the exit status in the future, you can use this
|
|
Packit |
ae235b |
call. For the case of a remote invocation, the remote process will
|
|
Packit |
ae235b |
typically exit when the last reference is dropped on cmdline
|
|
Packit |
ae235b |
. The
|
|
Packit |
ae235b |
exit status of the remote process will be equal to the last value
|
|
Packit |
ae235b |
that was set with this function.
|
|
Packit |
ae235b |
In the case that the commandline invocation is local, the situation
|
|
Packit |
ae235b |
is slightly more complicated. If the commandline invocation results
|
|
Packit |
ae235b |
in the mainloop running (ie: because the use-count of the application
|
|
Packit |
ae235b |
increased to a non-zero value) then the application is considered to
|
|
Packit |
ae235b |
have been 'successful' in a certain sense, and the exit status is
|
|
Packit |
ae235b |
always zero. If the application use count is zero, though, the exit
|
|
Packit |
ae235b |
status of the local GApplicationCommandLine is used.
