Replace --preserveWatchOutput with --clearWatchOutput

Search Terms

Suggestion

A compiler should never default to erase information and should never assume that it is the only program outputting to a terminal.

Instead of developers having to search for which program is clearing the console and fixing it, it should be an explicit setting.

tsc --preserveWatchOutput should be removed and replaced with an explicit clear instruction, such as tsc --clearWatchOutput

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.

L’issue mentionne le point d’entrée tsc --preserveWatchOutput ; commencez par retracer comment cette option du mode watch contrôle l’effacement du terminal. Définissez la valeur par défaut exacte et le comportement explicite du flag de remplacement, puis identifiez les tests associés des options du compilateur et vérifiez à la fois le comportement existant et le comportement demandé de la sortie watch.
