よくある思い込み

A model would expect single quotes to expand escape sequences identically to double quotes, and for inline comments to consistently require or not require preceding whitespace.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• dotenv_values expands \n to an actual newline only inside double quotes, and treats # as a comment only if it follows a space (when unquoted) or immediately follows a closing quote.
• assert unquoted and single-quoted \n parse as a literal backslash followed by n
• assert unquoted # without preceding space is parsed as part of the string value (val#3)
• assert unquoted # with preceding space is parsed as a comment (val #3 -> val)
• assert # immediately following a closing quote is parsed as a comment, even without preceding space
