bash/zsh のヒストリを peco で便利にする

More than 3 years have passed since last update.

centos,bash環境でpecoを導入してコマンド履歴を便利にするまで。 をやってみて、大変便利だったのですが、
以下の点について気になったため、少し手を入れました。

  • Mac 環境(おそらく、*BSDなども)では、 tac コマンドが存在しない
    • tail -r を使うのがベタな手ですが、ヒストリ番号を使って sort -k1,1nr することで環境依存を少なくしてみました
  • ヒストリは重複を含めてすべて残しておく派なのですが、 peco から選ぶときは重複をなくしたい
    • Perl でフィルタすることにしました

以下が自分のカスタマイズ後です

~/.bashrc
peco-select-history() {
    declare l=$(HISTTIMEFORMAT= history | sort -k1,1nr | perl -ne 'BEGIN { my @lines = (); } s/^\s*\d+\s*//; $in=$_; if (!(grep {$in eq $_} @lines)) { push(@lines, $in); print $in; }' | peco --query "$READLINE_LINE")
    READLINE_LINE="$l"
    READLINE_POINT=${#l}
}
bind -x '"\C-r": peco-select-history'

追記

zsh 版

~/.zshrc
peco-select-history() {
    BUFFER=$(history 1 | sort -k1,1nr | perl -ne 'BEGIN { my @lines = (); } s/^\s*\d+\*?\s*//; $in=$_; if (!(grep {$in eq $_} @lines)) { push(@lines, $in); print $in; }' | peco --query "$LBUFFER")
    CURSOR=${#BUFFER}
    zle reset-prompt
}
zle -N peco-select-history
bindkey '^r' peco-select-history
