====== Preparation ======
  - get and install iTerm
  - install brew
  - get and install font
  - get solarized theme
  - install zsh, oh-my-zsh

====== Settings ======
  - setting on iterm
    - theme
    - text
  - setting zsh as default
  - set theme in ~/.zshrc
  - set other stuffs in ~/.oh-my-zsh/themes/agnoster.zsh-theme


<sxh bash>
echo "\ue0b0 \u00b1 \ue0a0 \u27a6 \u2718 \u26a1 \u2699”
</sxh>

====== Others ======

====== 프롬프트 사용자 이름 삭제 ======
$ vim ~/.zshrc

<sxh bash>
prompt_context() {
  if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
    prompt_segment black default "%(!.%{%F{yellow}%}.)$USER"
  fi
}
</sxh>

====== Word jump 활성화하기 ======

<sxh>
## word jumps 활성화 하기
- 기본적으로 oh-my-zsh에서는 `option + 방향키` 조합의 단어별 이동이 불가능하다. 이를 수정하려면 별도의 설정수정이 필요하다.
- iTerm -> Preferences -> Profiles -> Keys 로 이동한다.
- `+` 버튼을 누르고 아래 설정을 추가한다.

```shell
# Option + right
⌥→
Send Escape Sequence
f
# Option + left
⌥←
Send Escape Sequence
b
</sxh>

====== Syntax Highlighting ======

<sxh>
# 설치
$ brew install zsh-syntax-highlighting

# ~/.zshrc 에 아래 문구 추가
source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
</sxh>

====== 테마변경 ======

<sxh>
vi .zshrc
ZSH_THEME="robbyrussell"
</sxh>

====== Multiline Prompt ======
<sxh>
vi ~/.oh-my-zsh/themes/agnoster.zsh-theme

## Main prompt
build_prompt() {
  RETVAL=$?
  prompt_status
  prompt_virtualenv
  prompt_context
  prompt_dir
  prompt_git
  prompt_bzr
  prompt_hg
  prompt_newline # 멀티라인 적용
  prompt_end
}

# 멀티라인 적용, 커버모양 변경
prompt_newline() {
  if [[ -n $CURRENT_BG ]]; then
    echo -n "%{%k%F{$CURRENT_BG}%}$SEGMENT_SEPARATOR
%(?.%F{$CURRENT_BG}.%F{red})$SEGMENT_SEPARATOR" # ❯%f"

  else
    echo -n "%{%k%}"
  fi

  echo -n "%{%f%}"
  CURRENT_BG=''
}
</sxh>
