get_ibus_addr: fix on x11

[symphorien]

this now returns a correct path on my machine, but I failed to use pmim on my machine. How to I set it up?

What went wrong when you run pmim ?

Thank you for your contribution !

What went wrong when you run pmim ?

when I run cargo run it runs fine but I don't know how to tell ibus to use it. Actually I'm not really interested in pmim, I have my own implementation of IBusEngine and I would like to know how to configure ibus to use it: what key combination should I type so that IBusEngine::process_key_event is triggered? (Note that I'm not really familiar with ibus, that may be a dumb question)

Add a file to /usr/share/ibus/component/pmim_ibrus.xml:

  </engines>
</component>

change <exec>/path/to/ibrus</exec> to the path of ibrus binary.

Then restart ibus-daemon.
Then you can add this new input method in ibus-setup.

You should not run ibrus directly, but switch input method with ibus.
Then ibus-daemon will run ibrus for you.

[secext2022]

When ibus-daemon start, it will read configuration files from /usr/share/ibus/component/*.xml, and register <component> and <engine> (input method).

Then switch input method with ibus, ibus will run binary as child process from <component> <exec> path.
Then ibus will send key event to the <engine>.
