ibus-anthy for default Japanese IME


The current default Japanese IME(input method engine) is ibus-kkc and the default is going to change to ibus-anthy to develop Japanese IME more effectively.


Current status

  • Targeted release: Fedora 34
  • Last updated: 2020-11-25
  • FESCo issue: <will be assigned by the Wrangler>
  • Tracker bug: <will be assigned by the Wrangler>
  • Release notes tracker: <will be assigned by the Wrangler>

Detailed Description

Currently some development plans have been pending because of the delay of ibus-kkc [1] which is the default IME for Japanese and I make the default IME to bring back to ibus-anthy now. Originally the default was changed from ibus-anthy to ibus-kkc because the upstream anthy is no longer updated. Recently I got the agreement with the original developer of anthy and forked it to anthy-unicode and start to change the default IME again.

I also considered about ibus-mozc for the default but the configuration GUI is based on Qt which has the different theme from GNOME desktop in Fedora.



Benefit to Fedora

Make the effective developments in the Japanese IME and apply the latest updates in ibus to each IME more effectively because I'm the maintainer of both ibus and ibus-anthy.
