boco

Bash Shell Function's Fuzzy Finder.

Requirements

  • grep
  • sort

Install

cd $HOME
git clone git@github.com:blacknon/boco.git
echo "source ~/boco/boco.bash" >> ~/.bashrc

Usage

Simple select

Basic usage is the method of selecting from the standard input received from the pipe.

echo {a..f}{01..03} | xargs -n3 | boco

History select

Can make history selection like peco or fzf. Load the following function.

__history_selection() {
  # 逆順に出力するコマンド
  if which tac >/dev/null; then
    local reverse="tac"
  else
    local reverse="tail -r"
  fi

  # 入力中の値をクエリとして渡すため、変数に代入
  case $(basename ${SHELL}) in
    zsh*)  local data="${BUFFER}" ;;
    bash*) local data="${READLINE_LINE}" ;;
  esac

  # selecterとしてbocoを指定
  local selecter="boco -p -q \"${data}\""

  # 長い行を表示させるための制御用ANSIエスケープを出力
  printf '\033[?7l'

  # shellに応じて処理を変える
  case $(basename ${SHELL}) in
    zsh*)
      BUFFER=$(history -n 1 | eval ${reverse} | awk '!a[$0]++' | eval "${selecter}") # 入力中のコマンドの内容を上書き
      CURSOR=${#BUFFER} # カーソル位置を移動
      ;;
    bash*)
      if [[ -n ${HISTTIMEFORMAT} ]];then # $HISTTIMEFORMATに値が入っている場合 => history番号とタイムスタンプを削除する
        local buffer=$(history | sed -r 's/^[ 0-9]+:* *[0-9]+ [0-9]{2}:[0-9]{2}:[0-9]{2} *:* *//g' | eval ${reverse} | awk '!a[$0]++' |eval ${selecter})
      else # $HISTTIMEFORMATに値が入ってない(空っぽ)場合 => history番号だけ削除する
        local buffer=$(history | sed -r 's/^ *[0-9*]+ +//g' | eval ${reverse} | awk '!a[$0]++' | eval ${selecter})
      fi
      READLINE_LINE="${buffer}" # 入力中のコマンドの内容を上書き
      READLINE_POINT=${#READLINE_LINE} # カーソル位置を移動
      ;;
  esac

  printf '\033[?7h'
}

# Ctrl + R でのhistoryの検索を__history_selection での処理に変更する
bind -x '"\C-r": __history_selection'

Use by ssh connection destination

Since boco is a shell function, it can be read directly from a local file to the ssh connection destination.

ssh -t user@hostname 'bash --rcfile <(echo '$(cat /path/to/boco/boco.bash|base64)'|base64 -d)'
