Setting FlagSet.ParseErrorsWhitelist.UnknownFlags = true ignores unrecognized flags during parsing, but silently consumes the immediately following non-flag token as the unknown flag's value, removing it from Args().

常见的想当然

Enabling ParseErrorsWhitelist.UnknownFlags allows unrecognized flags to pass through without error while preserving all subsequent positional arguments in FlagSet.Args().

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

• When ParseErrorsWhitelist.UnknownFlags is true, FlagSet.Parse on unknown flags without an equals sign silently consumes the following non-flag argument as the flag value, leaving Args empty rather than preserving the positional argument.
• When ParseErrorsWhitelist.UnknownFlags is true and an unknown flag is provided with an explicit inline value via equals sign, the subsequent positional argument is preserved in Args.
• When ParseErrorsWhitelist.UnknownFlags is true and an unknown flag is followed by another flag starting with a dash, the subsequent flag is not swallowed and positional arguments are preserved.
• When ParseErrorsWhitelist.UnknownFlags is false by default, FlagSet.Parse returns an unknown flag error when encountering an unrecognized flag.
