brew (un)?instal にはaliasが張られている ~ パッケージマネージャーには意外とある

Posted at

Qiitaの記事内で、間違えそうもない人がコマンドで
brew instal ~
というタイポを書いているのを見て、少し引っかかったので調査。

legacy-homebrew/global.rb at master · Homebrew/legacy-homebrew

HOMEBREW_INTERNAL_COMMAND_ALIASES = {
  "ls" => "list",
  "homepage" => "home",
  "-S" => "search",
  "up" => "update",
  "ln" => "link",
  "instal" => "install", # gem does the same

新しい方でも

HOMEBREW_INTERNAL_COMMAND_ALIASES = {
  "ls" => "list",
  "homepage" => "home",
  "-S" => "search",
  "up" => "update",
  "ln" => "link",
  "instal" => "install", # gem does the same
"uninstal" => "uninstall",

# gem does the sameとコメントにあるように、Rubyのgemでも同様にinstalでインストールできる。

PHPのComporserでも出来て、pipやnpmではミスとするものの、installをサジェストしてくれる。

意外にnpmに比してyarnは単純なエラーとなり、yumも同様。

恐らく打ち間違いを助けるためのaliasだと思われるが、デフォルトで正常に動くコマンドに対してtypoと言い切っていいものか悩む。記事にするならば正しい英単語のほうが望ましいとは思うのだが…。
