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.

Das Issue nennt den Einstiegspunkt tsc --preserveWatchOutput; beginne damit nachzuverfolgen, wie diese Watch-Modus-Option das Leeren des Terminals steuert. Definiere den genauen Standardwert und das explizite Verhalten des Ersatz-Flags, identifiziere anschließend die zugehörigen Compiler-Options-Tests und überprüfe sowohl das bestehende als auch das angeforderte Verhalten der Watch-Ausgabe.
