Pathname
# relative _ path _ from(base _ directory) -> Pathname (21606.0) -
base_directory から self への相対パスを求め、その内容の新しい Pathname オブジェクトを生成して返します。
...se_directory から self への相対パスを求め、その内容の新しい Pathname
オブジェクトを生成して返します。
パス名の解決は文字列操作によって行われ、ファイルシステムをアクセス
しません。
self が相対パスなら base_directory......絶対パスなら
base_directory も絶対パスでなければなりません。
@param base_directory ベースディレクトリを表す Pathname オブジェクトを指定します。
@raise ArgumentError Windows上でドライブが違うなど、base_directory から self への相対パ......スが求められないときに例外が発生します。
