Add the D-Bus API definition and its implementation in the form of a GPIO manager daemon and a companion command-line client as well as some additional configuration and data files (systemd service, example udev configuration, etc.) and test suites.

TODO list for libgpiod
|
|
|
|
==========
|
|
|
|
This document contains the list of things I'd like to have in libgpiod before
|
|
declaring it "mostly feature-complete". If anyone wants to help, this can
|
|
serve as the starting point.
|
|
|
|
==========
|
|
|
|
* implement a simple daemon for controlling GPIOs in C together with a client
|
|
program
|
|
|
|
This is by far the lowest priority task. Similarly as with the dbus daemon:
|
|
the goal is to provide a centralized agent controlling GPIOs with a simple
|
|
interface consisting of a command line client communicating with the server
|
|
over unix sockets.
|
|
|
|
In this case however the goal is to have as few dependencies as possible. This
|
|
is because for some small systems dbus is overkill. Since we won't be using any
|
|
standardized protocol, it will take much more effort to implement it correctly.
|
|
|
|
----------
|
|
|
|
* improve gpioset --interactive tab completion
|
|
|
|
The existing tab completion uses libedit's readline emulation layer which
|
|
has a few limitations, including not being able to correctly handle quoted
|
|
line names and being disabled when stdin/stdout are not a tty (which makes
|
|
testing with gpio-tools-test.bash using coproc problematic).
|
|
|
|
One approach that could address both these problems is to bypass the readline
|
|
emulation and use the libedit API (histedit.h) directly.
