If we abolish built-in R snippets (a move I describe in #7234 and posit-dev/ark#779), this problem would go away. A user's custom R snippets could still appear in this context, but that would come up much less often. This is also only really a problem with snippets where the prefix is exactly the name of a function. |

For posit-dev/ark#782 Addresses #7234 Addresses #3108 ### Release Notes #### New Features - R snippets are now handled in the conventional way for VS Code, i.e. via optional `.code-snippets` files at the user or workspace level or an R-specific `r.json` file. Newly configured snippet files contain examples for R and Python. The only R snippets that remain built-in are those relating to reserved words (#7234). #### Bug Fixes - It is now possible to get completions via `?` for functions, e.g., in the `apply()` family or for `switch()` (#3108). ### QA Notes <!-- Add additional information for QA on how to validate the change, paying special attention to the level of risk, adjacent areas that could be affected by the change, and any important contextual information not present in the linked issues. -->

It's hard to request help via
?for a function that is a snippet. You can't benefit from the completion without getting more than you bargained for.At first I thought this was just an add-on to #2338, but then I realized that my chosen example (
lapply()) isn't just getting unwanted parentheses (basically harmless, I suppose), but also getting a full function signature, which truly does break the?call.What's special about
lapply()? It's one of our built-in snippets.https://github.com/posit-dev/amalthea/blob/486dc8bfa516ea45eb4eaddb19b2128bf51f679d/crates/ark/resources/snippets/r.code-snippets#L113-L117
I wish I could type
?lapthen mash enter to get?lapplythen mash enter again to see help.Screen.Recording.2024-05-10.at.3.02.53.PM.mov
