Hello, recently I've been playing around with fcitx5 and getting it to work in guix. Currently I don't have the time to better document my results, but with the intention of helping others with similar issues I've decided to write this mail instead.
* Setup The first thing is installing a font, so the characters get rendered correctly. Fonts for displaying CJK characters (there are also others available) font-google-noto-serif-cjk font-google-noto-sans-cjk Next the packages for fcitx5. From the following list probably not all packages are required (some may be implicitly used as the inputs of others). I still need to check which ones are strictly necessary. Packages fcitx5 fcitx5-gtk fcitx5-gtk:gtk2 fcitx5-gtk:gtk3 fcitx5-gtk4 fcitx5-qt fcitx5-configtool ;; This is for Japanese input only. See the repositories to check ;; which package you need for other languages fcitx5-anthy ;; Probably not necessary, as fcitx5-anthy probably already includes it anthy * Environmental variables IBus exports the some environmental variables in order for GTK to be able to find the input manager modules. The same is necessary for fcitx5. However, this was apparently forgotten when creating the package definition. Until this is change, one can use the following (assuming fcitx5 was installed in your home profile) export GUIX_GTK2_IM_MODULE_FILE="$HOME/.guix-home/profile/lib/gtk-2.0/2.10.0/immodules-gtk2.cache" export GUIX_GTK3_IM_MODULE_FILE="$HOME/.guix-home/profile/lib/gtk-3.0/3.0.0/immodules-gtk3.cache" I can't speak/read Chinese so I couldn't read the article, but in principle here is the source: https://guixcn.github.io/wiki/input-method/ * Sway Currently sway does not support 'text-input-v3' and the candidate list disappear/flicker. In my case this is observed as a spike in CPU usage and increase of temperature. To solve this you can define the following environmental variables. export GTK_IM_MODULE"="fcitx" export QT_IM_MODULE="fcitx" export "XMODIFIERS"="@im=fcitx" Fcitx5 will then throw an annoying warning each time it starts recommending to disable the environmental variables. A easy fix is to wrap fcitx5 in a script with the variables unset. fcitx5.sh ------------------------------------------------------------------------ #!/bin/sh unset GTK_IM_MODULE fcitx5 ------------------------------------------------------------------------ If I understand correctly, this issue will be solved in the next release (sway v1.10) and the environmental variables will no longer be necessary. https://github.com/swaywm/sway/pull/7226 I hope this helps. Please comment if you find any errors in this setup or have further things to add. Thanks in advance. Regards, Thomas Albers Raviola
