Häufige Annahme

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.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• 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
