Experience Improvement

Auto Suggestions

• zsh-autosuggestions https://github.com/zsh-users/zsh-autosuggestions

Fonts

• Powerline fonts https://github.com/powerline/fonts
• JetBrains Mono https://www.jetbrains.com/lp/mono/

Theme

• By default, robbyrussell theme is using in oh-my-zsh but you can change it to other themes. My suggestion is Spaceship ZSH. It's simple and better than any other themes.
• To install the spaceship theme, you might want to go through the guideline or using the following for quick started

git clone https://github.com/denysdovhan/spaceship-prompt.git "$ZSH_CUSTOM/themes/spaceship-prompt"
ln -s "$ZSH_CUSTOM/themes/spaceship-prompt/spaceship.zsh-theme" "$ZSH_CUSTOM/themes/spaceship.zsh-theme"

Configuration

iTerm2

• Open iTerm2 Preferences > Profiles > Text
  • Change the font to Cousine for Powerline or JetBrains Mono
  • Adjust the font size to 14 or your preferred one
  • Check Use ligatures and Anti-aliased options
• Open iTerm2 Preferences > Profiles > Window
  • Adjust Transparency to your prefer
  • Check Blur and adjust it
• Open iTerm2 Preferences > Profiles > Terminal
  • Check Unlimited scrollback

Update .zshrc

• Change the theme as ZSH_THEME="spaceship"
• To disable current Kubernetes context info you might want to put SPACESHIP_KUBECONTEXT_SHOW="false"
• Load Oh My Zsh plugins plugins=(git osx mvn docker kubectl helm zsh-autosuggestions)
• Keep source ~/.profile before source $ZSH/oh-my-zsh.sh if you want to config/reuse your .profile
• Your later customizations (not for oh-my-zsh) need to put after the line of source $ZSH/oh-my-zsh.sh
• After all, remember running source .zshrc to update the changes.
