RubyでJSON/XMLをPretty Printするgem prettyprint

ファイルまたは標準入力から受け取ったJSON/XMLをインデント表示するRuby製のツールprettyprintをgemで公開しました。

インストール

$ gem install prettyprint

使い方

prettyprint [json|xml] [filepath]

gemでインストールするとprettyprintコマンドが使えるようになります。prettyprintコマンドはxmlまたはjsonというサブコマンドを持ちます。ファイル名を指定するとそのファイルを入力とします。

$ prettyprint json input.json

ファイル名を省略すると、標準入力を受け付けます。

$ echo '<html><title>prettyprint</title><body>happy pretty printing</body></html>' | prettyprint xml
<html>
 <title>
  prettyprint
 </title>
 <body>
  happy pretty printing
 </body>
</html>
