Bug Summary and Steps to Reproduce

Bug Summary:

When I autocomplete a param it deletes the content on the right side of the line

c++_autocomplete.mp4

Steps to reproduce:

1. Copy this code

struct Something {
    int something;
};
struct Foo {
    Something first, second;
};

Foo foo;
foo.first.something;

2. delete first. and place the cursor just after foo
3. command + space or ctrl + space (in windows) to toggle the autocomplete menu
4. select option (see video above)

Expected behavior:

I will like the behaviour I usually get when working with typescript, where when I call the autocomplete it respects what is written on the right of the line (see video below)

js_autocomplete.mp4

This is "by design". You can get the behavior you want by using

    "[cpp]": {
        "editor.suggest.insertMode": "insert"
    }

See the change at #4892 .

However, I'm not sure why we changed that setting to replace, so we can change it back to "insert" as the default.

Thanks! It works fine now

[sean-mcmanus]

Yeah, we may want to update our default insertion mode though so users don't have to use that setting, not sure yet.

This issue prevails, even with "editor.suggest.insertMode": "insert", "[cpp]": { "editor.suggest.insertMode": "insert" }:

I would expect the editor with the above settings to never ever ever delete characters, e. g. expect the following outcome:

@Longhanks Yes, our autocomplete behavior in your example matches VS and not TypeScript, i.e. even in insert mode it may do a replace. I've moved your request to #10613 .
