How to show default values and types of keyword arguments?

[bowenszhu]

using DocStringExtensions

"""
$(TYPEDSIGNATURES)
"""
function func(a::Integer, b::Integer = a; c::Integer = b)::Integer
    a + b + c
end

@doc func

gives

  func(a::Integer) -> Integer
  func(a::Integer, b::Integer; c) -> Integer

TYPEDSIGNATURES returns a simplified representation of method signatures, which, however, doesn't show the types and default values of keyword arguments. Is there a convenient way to also include them in the docstring?

The expected result is

func(a::Integer, b::Integer = a; c::Integer = b) -> Integer
