Allow multiple node selections

amyjko commented 1 year ago

What's the problem?

In the code editor, the Caret allows for two types of selection: an insertion index in the text buffer, or a single Node.

That's fine for many cases, but doesn't work well for cases such as:

Selecting a subsequence of a list of nodes (e.g. a set of statements in a block, part of a list literal)
Selecting multiple expressions from disparate places

What's the idea?

Add Node[] to Caret and handle in a reasonable way in every single place required by TypeScript. This would be a major revision, requiring utmost care and decisions about how to handle all current editing functionality.

Who benefits?

All creators who are editing a program.

Design ideas

TBD

Hi @amyjko, are you still working on this issue?

Unassigned myself; I was ambitious, but still haven't gotten around to it.
