First backup your old ibus-rime config.
This uses Luna Pinyin and Aurora Pinyin, so you need to install rime-luna-pinyin from official repo and rime-aurora-pinyin-git or rime-aurora-pinyin (This one is not frequently updated so I packaged the -git one) from AUR. It also depends on rime-emoji for emoji (only use it's opencc dict, I have a custom patch) and rime-pinyin-zhwiki for extended dictionary. If you are Arch Linux users, just run those commands to install them all (thanks to felixonmars).
# pacman -S librime ibus-rime rime-luna-pinyin rime-emoji rime-pinyin-zhwiki
$ paru rime-aurora-pinyin-git
If you are not Arch Linux users, I assume you know how to get those config for RIME, because I don't know.
Then clone this repo.
$ git clone https://github.com/AlynxZhou/alynx-rime-config.git ~/.config/ibus/rime
About emoji related stories, see https://github.com/rime/rime-emoji/blob/master/README.md#%E8%87%AA%E5%8A%A9%E5%AE%89%E8%A3%9D, rime/rime-emoji#16 and hosxy/rime-aurora-pinyin#13.
Then trigger RIME's deploy. ibus restart or ibus-daemon -rdx or click deploy button (recommanded).
