RubyでANSIカラーシーケンスを学ぼう！ - hp12c
ブログを下記に移転しました。デザイン変更により移転先では記事が一層読みやすくなっていますので、よろしければ移動をお願い致します。 RubyでANSIカラーシーケンスを学ぼう！ : melborne.github.com - CUIの世界は地味な世界です 真っ黒なターミナル画面に単一色の文字列 それが却って落ち着くという向きもありますが 今となってはその地味さは際立っています ターミナルで色を使う方法を学ぶことで 新しい世界が開けるかも知れません ようこそANSIカラーの世界へ エスケープシーケンス ターミナルで色を使うためには エスケープシーケンスというものを利用します エスケープシーケンスはターミナル上で色を含む特定の制御を 実現するための特殊な文字列です print "\e[31mhello\e[0m" これによりターミナル上に青文字で「hello」と出力されます この"\e[31m"
