Emit Numerical Literal with different TokenFlags

Search Terms

emitter, numerical

Suggestion

Currently, all Numerical Literal has been emitted as Decimal number.
Hope to allow emit Hex Literal or Binary Literal etc

Use Cases

ts.createLiteral('2', TokenFlags.BinarySpecifier) // 0b10

That is useful to create a codegen

Examples

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Comienza localizando la implementación y los usos de ts.createLiteral y TokenFlags, y después revisa el pull request relacionado enlazado en el issue. Determina cómo se emiten actualmente los literales numéricos y qué cambios son necesarios en la API y el emitter. Se considerará completado cuando los flags de literales binarios, hexadecimales u otros solicitados produzcan la forma de código fuente prevista sin cambiar el comportamiento existente.
