this would also change non-whitespace tabs. i think we should change the term interface itself to deal with tabs

[antsmartian]

@devsnek Could you please explain on what you mean by "this would also change non-whitespace tabs."? Sorry, I didn't get that.

@antsmartian it's about e.g. const a = 'foo\tabc'. The tab would be replaced with a whitespace and that's not intended at all.

I just tried to only replace the tabs while visualizing the input but the cursor is still off in those cases. So the only real option I see is to teach readline to position the cursor at the correct position in case tabs are used.

I am just cleaning up some old REPL issues and PRs. This approach sadly can not work properly, so I'm closing this. Please reopen or open a new PR if someone wants to follow up on this.
