Add semicolon as a commit character for object creation and symbol completion #48851

Cosifne · 2020-10-22T18:24:55Z

When trying to complete a method or a type in object creation context by a semicolon, append ();
Put the caret between parenthesis based on if the method/constructor takes a parameter.

Partially resolved #12363

Also need to sync with the intellicode team to make some similar changes to PythiaCompletionProvider.

I couldn't figure out the best area label to add to this PR. If you have write-permissions please help me learn by adding exactly one area label.

Also need to sync with the intellicode team to make some similar changes to PythiaCompletionProvider.

In addition to that, I think this could be supported by import completion as well. For those items, we either can recover the symbol from item (for extension methods) or have the fully qualified name to find the symbol from compilation (for type).

I have some perf concerns, let's figure out if the calculation can be reduced and delay to commit time (also, it might worth to get some perf traces to confirm it.) And ideally, I'd like to implement this feature in all relevant providers to ensure a consistent user experience, at least for the ones we own if coordinating with intellicode team takes time.

Also, I remember we spent a bunch of time dogfooding the statement completion feature, do we want to do the same for this (either dogfooding private built vsix or via experiment)?

The code is much easier to understand now, thanks :)

Consider add a few tests to CSharpCompletionCommandHandlerTests. Those tests behave like semi-integration tests since they go through async completion layer as well.

LGTM, just some minor comments. Are you planning to add "." support next?

Add comment that this is used like a flag so value doesn't matter

Not sure if you added this because you saw my (now deleted) comment, but I think this is actually unnecessary, since intelliccode controls both creation of the item and create the change

TIL this is not allowed :)
