alacritty + tmux で true color対応したい

Posted at

よく見かける設定例

同じような環境で使っている人の設定ファイルを見ると、下記のような設定が多く見られる

alacritty.yml
env:
  TERM: xterm-256color
.tmux.conf
set -g default-terminal "tmux-256color"
set -ag terminal-overrides ",xterm-256color:RGB"

確かに、これでもtrue color表示できるけど、$TERMをalacrittyに設定したい

そもそもtrue color表示できているかの確認

下記コマンドを実行

curl -s https://gist.githubusercontent.com/lifepillar/09a44b8cf0f9397465614e622979107f/raw/24-bit-color.sh | bash

true color表示できている場合

こんな感じで継ぎ目がなく表示されればtrue color表示できている

true color表示できていない場合

対応できていない場合は、こんな感じに継ぎ目が明らかになる

結論

下記設定でtrue color対応できる

alacritty.yml
env:
  TERM: alacritty
.tmux.conf
set -g default-terminal "tmux-256color"
set -ag terminal-overrides ",alacritty:RGB"

参考
