Ubuntuでzshを使おう

概要#

Ubuntuの使い勝手を良くしていきます。

zshへの切り替え#

sudo apt install zsh -y
chsh

パスワード入力を求められたら/usr/bin/zshと入力する。

Homebrewの導入#

sudo apt install -y build-essential procps curl file git
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

エンターを押すとインストールが始まる。終わったら以下のコマンド入力。

(echo; echo 'eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"') >> /home/mini/.zshrc
eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"

Node Version Manager#

brew install nvm

でインストールが始まる。

mkdir ~/.nvm
export NVM_DIR="$HOME/.nvm"
[ -s "/home/linuxbrew/.linuxbrew/opt/nvm/nvm.sh" ] && \. "/home/linuxbrew/.linuxbrew/opt/nvm/nvm.sh"  # This loads nvm
[ -s "/home/linuxbrew/.linuxbrew/opt/nvm/etc/bash_completion.d/nvm" ] && \. "/home/linuxbrew/.linuxbrew/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion

とすれば反映される。

Git#

mkdir ~/.zsh
cd ~/.zsh
curl -o git-prompt.sh https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh
curl -o git-completion.bash https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash
curl -o _git https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.zsh

現在いるブランチとかが表示される、便利。

# GIT
source ~/.zsh/git-prompt.sh
fpath=(~/.zsh $fpath)
zstyle ':completion:*:*:git:*' script ~/.zsh/git-completion.bash
autoload -Uz compinit && compinit

GIT_PS1_SHOWDIRTYSTATE=true
GIT_PS1_SHOWUNTRACKEDFILES=true
GIT_PS1_SHOWSTASHSTATE=true
GIT_PS1_SHOWUPSTREAM=auto

# NVM
export NVM_DIR="$HOME/.nvm"
[ -s "/home/linuxbrew/.linuxbrew/opt/nvm/nvm.sh" ] && \. "/home/linuxbrew/.linuxbrew/opt/nvm/nvm.sh"
[ -s "/home/linuxbrew/.linuxbrew/opt/nvm/etc/bash_completion.d/nvm" ] && \. "/home/linuxbrew/.linuxbrew/opt/nvm/etc/bash_completion.d/nvm"

# Load NVM
autoload -U add-zsh-hook
load-nvmrc() {
  if [[ -f .nvmrc && -r .nvmrc ]]; then
    nvm use
  elif [[ $(nvm version) != $(nvm version default)  ]]; then
    echo "Reverting to nvm default version"
    nvm use default
  fi
}
add-zsh-hook chpwd load-nvmrc
load-nvmrc

# Load VENV 
autoload -U add-zsh-hook
load-pyenv() {
  if [[ -r .venv ]]; then
    source .venv/bin/activate
  elif [[ -n "$VIRTUAL_ENV" && $PWD != ${VIRTUAL_ENV%/*} && $PWD != ${VIRTUAL_ENV%/*}/* ]]; then
    deactivate
  fi
}
add-zsh-hook chpwd load-pyenv
load-pyenv

# Load Rbenv
[[ -d ~/.rbenv  ]] && \
  export PATH=${HOME}/.rbenv/bin:${PATH} && \
  eval "$(rbenv init -)"

# Fig
[[ -f "$HOME/.fig/shell/zshrc.post.zsh" ]] && builtin source "$HOME/.fig/shell/zshrc.post.zsh"

これで変更が効かないときはexec zshを実行すると良い。

Ubuntu Zsh (via Vagrant) is not locating Zsh or its functions
