Functions not being properly recognized in 2.6.1

[lukakoning]

In version 2.6.1, functions are not properly recognized when accessing via '$' sign. This means you can no longer see it is a function, you don't get the automatic '()' when accessing it, and you also aren't shown the arguments of the function.

For illustration, this is how they used to show in 2.5.1:

Now in 2.6.1:

I am on:

R version 4.4.1 (2024-06-14 ucrt)
Platform: x86_64-w64-mingw32/x64
Running under: Windows 10 x64 (build 19045)

(RSTudio 2024.09.0 Build 375)

Does it exhibit that behavior with this code?

library(R6)
AC <- R6Class("AC",
    public = list(
        x = 1
    )
)

a <- AC$new()

# Press <tab> below
a$

And if not, can you provide a reproducible example?

@wch With this I can reproduce it:

AC <- R6::R6Class(
  "AC",
  public = list(
    x = 1,
    y = function(some_argument = "default") {
      print(some_argument)
    }
  )
)

a <- AC$new()

So then under 2.6.1 you see 'y' as a regular (purple) field and not as a function (blue):

This is how it should be (correct under 2.5.1 and also 2.6.0):

So then it seems related to the change made in 2.6.1 regarding ".DollarNames.R6(), avoid use of NextMethod()" (#298).

I was not able to reproduce on my personal PC where I was using R 4.4.2 and also R 4.1.3, but with a newer build of RStudio. So it may be related to the RStudio IDE most likely, as the change made in 2.6.1 was also made for an issue with the RStudio IDE. To recall, this bug occurs under RSTudio 2024.09.0 Build 375.

Does the issue persist with the latest daily builds of RStudio? https://dailies.rstudio.com
