動機
- Karabinerのvkopenurldef素晴らしすぎて泣ける
- 簡単に追加できるようにしたい
使用ツール
xmlstarlet
- コマンドラインでXML解析・編集
$ brew install xmlstarlet
$ type xmlstarlet
xmlstarlet is /usr/local/bin/xmlstarlet
$ type xml
xml is /usr/local/bin/xml
GNU sed
- xmlstarletだとネストした要素を追加するのが超かったるいので
- メタキャラクタ
\nを使いたいので
$ brew install gnu-sed
$ type gsed
gsed is /usr/local/bin/gsed
MacVim
$ brew cask install macvim
$ type mvim
mvim is /usr/local/bin/mvim
pygmentize
