常见的想当然
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.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- 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
