描述

Hello,

Is there a way to allow a key to be a boolean or a string? For example, I'd allow '--no-attribute' which would give attribute a false boolean, as well as '--attribute inline' which would give attribute the value of 'inline'?

Thanks!

研究方向
Investigate how yargs currently handles boolean options and string options. The relevant code likely resides in the parser or validation modules (e.g., lib/usage.js or lib/validation.js). Look at existing behavior for ' no *' prefixes. Consider implementing support for a new option type that accepts both boolean and string values, possibly by introducing a new configuration property like 'type: ['boolean', 'string']'. Check if there are any related issues or PRs that discuss this feature. The issue itself is a feature request with no maintainer response, so any implementation should be proposed with tests and documentation.
