zshに移行してみた

Posted at

経緯

1年くらいArchlinuxを使っていて,fishを普段使いしているが,最近macbookを使う機会がありzshも案外悪くないかもしれないと思い移行することにした。

zshはPOSIX準拠なので問題が発生しづらいという利点もある。

本体のインストール

yay -S zsh

これだけ

zsh

でzshに移動しておく

カスタマイズ

お好きなエディタで.zshrcを弄っていく

nvim ~/.zshrc

フレームワーク

どうやらZimというzshのフレームワークがあるらしい。

これを使うとlsやgit関連のコマンドのエイリアスなどの便利機能を追加してくれる。

インストールはこれでできる

curl -fsSL https://raw.githubusercontent.com/zimfw/install/master/install.zsh | zsh

ヒストリ関連

どうやら上キーで呼びだせるコマンドの履歴をヒストリと言うらしい。

通常ではターミナルを起動してから閉じるまでしか保存されないため,別にファイルを作りそこに保存しておく。

.zshrc
export LANG=ja_JP.UTF-8
HISTFILE=$HOME/.zsh-history
HISTSIZE=1000000
SAVEHIST=1000000
setopt share_history # 複数ターミナルでヒストリの共有

テーマ

powerlevel10kを導入する

yay -S --noconfirm zsh-theme-powerlevel10k-git

公式によるとコミュニティパッケージはよく壊れるから使ってはいけないらしい。

zshrcにpowerlevel10kを読み込ませる

.zshrc
source /usr/share/zsh-theme-powerlevel10k/powerlevel10k.zsh-theme

source .zshrcするとpowerlevel10kの設定画面が出てくるので指示された選択肢から自分の好みに合わせる。
設定をやり直したい場合はzshrcに書いている通りp10k configureを実行すればよい。

プラグイン

zplugにしようと思ったがRust製の高速なプラグインマネージャーのsheldonというものを使ってみることにした。

インストール

yay -S sheldon

zshにsheldonをロードさせる

.zshrc
eval "$(sheldon source)"

ここからはplugins.tomlを弄っていく

nvim ~/.config/sheldon/plugins.toml

基本的にはgithubのリポジトリを書いていくだけ

pluginsテーブル配下に書いていく

まずzsh-completions(補完強化)を導入する

.config/plugins.toml
[plugins.zsh-completions]
github = "zsh-users/zsh-completions"

こんな感じで指定した後,sheldon sourceを実行すれば適用される。

lsの強化

lsの上位互換であるlsd(ls-deluxeの略で,決して違法薬物ではない)を紹介する。

yay -S lsd

これでインストールできる。
あとは.zshrcにaliasを設定すればOK

.zshrc
alias ls='lsd'
alias l='lsd'
alias ll='lsd -l'
alias la='lsd -a'
alias lla='lsd -la'
alias lt='lsd --tree'

こんな感じになる

終わりに

割と快適なターミナル環境になったのではないだろうか。

最後に.zshrcsheldon/plugins.tomlを晒して終わりとする。
