Hi,

the update-alternative approach needs to adjust every ibus/fcitx/fcitx5
package and write their own generator scripts=E2=80=A6it may be too hard fo=
r an
input method framework maintainer to know everything about systemd=E2=80=A6

Currently my generator supplements systemd and a dummy =E2=80=9Cinputmethod=
=E2=80=9D
package, so any package provides =E2=80=9Cinputmethod=E2=80=9D can use this=
 generator.

The $LANG and .i18n can be added later, it=E2=80=99s easy actually.  After =
these
works, I think maybe we can remove Provides: lang(zh:ja:ko) tags from
packages too.

actually this time I made the request  just to split the generator from
fcitx5 to benefit others, with no other further design/considerations, and
I know the generator is just a skeleton now :-)

<br>
Thank you for working to support IM on Wayland sessions.<br>
<br>
I see your systemd-inputmethod-generator.<br>
<a href=3D"https://build.opensuse.org/package/show/M17N/systemd-inputmethod=
-generator" rel=3D"noreferrer" target=3D"_blank">https://build.opensuse.org=
/package/show/M17N/systemd-inputmethod-generator</a><br>
<br>
It simply read a list of input methods and precedence from <br>
(/usr)/etc/X11/xim.d/en. I think it is ok nowadays since we do not need com=
plex <br>
mechanisms provided by /etc/X11/xim anymore.<br>
<br>
But I&#39;m wondering how about using `update-alternatives` instead of read=
ing <br>
/etc/X11/xim.d/en. A benefit of using update-alternatives is users can choo=
se an <br>
input method by `update-alternatives --config` or YaST. `update-alternative=
s` is <br>
also used to configure a default display manager.<br>
<br>
To use update-alternatives, firstly, we prepare:<br>
[1] /usr/lib/input-method/user-environment-generators/fcitx<br>
[2] /usr/lib/input-method/user-environment-generators/ibus<br>
<br>
And run `update-alternatives --install` during installation:<br>
update-alternatives --install \<br>
=C2=A0 =C2=A0 /usr/lib/systemd/user-environment-generators/29-input-method-=
generator \<br>
=C2=A0 =C2=A0 input-method-user-environment-generator \<br>
=C2=A0 =C2=A0 /usr/lib/input-method/user-environment-generators/fcitx \<br>
=C2=A0 =C2=A0 25<br>
<br>
The following symlink to one of above will be generated:<br>
/usr/lib/systemd/user-environment-generators/29-input-method-generator<br>
<br>
<br>
Note that if [1] and [2] does not contain any program, the file managed by =
<br>
`update-alternatives` can be /lib/environment.d/99-input-method.conf<br>
<br>
<br>
What do you think?<br>
<br>
If you plan to extend your input-method-generator so that it can read <br>
/etc/X11/xim.d/$LANG and/or ~/.i18n, etc., the current approach will be app=
ropriate.<br>
