Julia 1.11.6 breaks keyword autocompletion in REPL for structures defined using @kwdef

[ronisbr]

Hi!

In Julia 1.11.5, the following works:

julia> @kwdef struct Test
           first = 2
           second = 3
       end
Test

julia> Test(; fi<TAB>
julia> Test(; first=

i.e., if you press TAB it correctly auto-completes the field name.

In Julia 1.11.6, on the other hand, we have:

julia> @kwdef struct Test
           first = 2
           second = 3
       end
Test

julia> Test(; fi<TAB>
fieldcount   fieldname    fieldnames   fieldoffset  fieldtype    fieldtypes
filemode     filesize     fill         fill!        filter       filter!
finalize     finalizer    finally      findall      findfirst    findlast
findmax      findmax!     findmin      findmin!     findnext     findprev
first        firstindex

I am pretty sure that the correct behavior should be the first one.

For the record, this is also broken on d268106

Hi! Btw, it is also broken in 1.12 RC 1. The last known version that I saw this working was on 1.11.5. Unfortunately, I could not build Julia on my machine to make a git bisect.

I finally managed to make a git bisect and the commit that started the problem is:

@KristofferC hi! Any ideia why that commit caused this problem?

[vtjnash]

That commit changed it so that only concrete functions would support autocomplete (not other things like Types)

Is it possible to revert that decision? I think most of the time you need kwargs auto complete in very large structures. This was very handy.

For example, it helps a lot when creating objects for those types of structures:

Bump!
