Replicate extendSelection in v6

v6
1

Hi!

I’m currently trying to convert a code from CodeMirror v5 to v6.

How could I replicate the extendSelection function from v5 in v6.

More specifically, I have this v5 code:

_doc.extendSelection(
    { ...from, ch: from.ch - 1 },
    { ...to, ch: to.ch + 1 }
);

How could I accomplish that in v6?

There’s nothing that really works like extendSelection, but you can use SelectionRange.extend to extend a single range, and you do view.dispatch({selection}) to set a new selection.

Thank you very much @marijn !

After setting the selection, how could I extract the text of the selection?
In v5 if I do this, it would return me the string of the selection:

_doc.getSelection()

In v6, I can do this:

editor.getSelection();

But it will return a object of type ITextSelection, but I’m not sure how to ge the content of the selection as a string.

… I don’t think you can.

You can read view.state.selection.ranges or view.state.selection.main to get the selected ranges (or the main range), and do view.state.sliceDoc(range.from, range.to) to get the part of the document covered by a given range.
