Shorthand for a function that returns kwargs

General Usage
1

Is it possible to create a function with kwargs that returns a kwargs NamedTuple like this get_abc(;a,b,c) = (a=a,b=b,c=c) without =(a=a,b=b,c=c)? Or need macroses ?

Since Julia 1.6+ or so, you can do this:

julia> get_abc(;a,b,c) = (; a, b, c)
get_abc (generic function with 1 method)

julia> get_abc(a=1, b=2, c=3)
(a = 1, b = 2, c = 3)

or this:

julia> get_kws(; kwargs...) = (; kwargs...)
get_kws (generic function with 1 method)

julia> get_kws(; a = 1, b = 2, c = 3)
(a = 1, b = 2, c = 3)

macro kwargs_return_function(f::Symbol, args...)
    _f = Symbol(:_,f)
    return :($(esc(
        quote
            $_f(; $(args...)) = nothing
            $f(; kwargs...) = ($_f(; kwargs...); (; kwargs...))
        end
    )))
end

better

macro kwret(f::Symbol, args...)
    return :($(esc(
        quote
            $f(; $(args...)) = (; $(args...))
        end
    )))
end

these functions are needed to control the arguments
