コマンドラインから emacs (emacsclient) を read-only で開く

Last updated at Posted at 2012-06-19

emacs 立ちあげてる状態なら C-xC-r (コマンド経由なら C-xfind-file-read-only) ってやれば、read-only でファイル開ける。じゃーそれをコマンドラインからやる時はどうするかって話。

emacs ならこんな感じ

function read_only_emacs() {
    [ -f "$1" ] || (echo "ファイルが見つかりませんでした: $1" >&2; exit 1)
    emacs "$1" --eval '(setq buffer-read-only t)'
}

ファイル見つからなくても emacs が立ち上がってしまうので、実行前に存在チェックしてる。

emacsclient ならこんな感じ

function read_only_emacsclient() {
    emacsclient -e "(find-file-read-only \"$1\")"
}

ただ、emacsclient -n で普段から使ってない人は、ちょっと違和感のある挙動かも。
