Hi Guix,

attached are three patches that show the current status of my work to
bring ibus-pinyin to Guix.  Unfortunately, it’s not working for me,
i.e. I can start ‘ibus-setup’ and add Chinese Pinyin or Chinese Bopomofo
to the enabled input methods, but no matter what I do: my selection of
input methods (cycling between methods is done with Super+Space by
default) has no effect on what I type.

To test this yourself I recommend deleting the following dirs:

    ~/.config/ibus
    ~/.cache/ibus

(Just in case.)  You probably also need to set IBUS_COMPONENT_PATH as
suggested by the ‘ibus’ package.

I also needed to run the dconf service, which can be started by running
‘$dconf/libexec/dconf-service’.  Without this service the ‘ibus-setup’
changes have no effect.

I played around with generating a GTK_IM_MODULES_FILE using
‘gtk-query-immodules-3.0’, but since I don’t know how to debug
ibus-pinyin, I didn’t continue to investigate there.

‘$out/libexec/ibus-setup-pinyin’ cannot be executed at all.

If someone could give me a hint how to debug this, I’d be very
grateful.  It all seems like magic to me, as I cannot see at what point
the translation from pinyin input to output characters fails.
