Hi,
I’d like a simple way of creating a “vector” of similar elements.
I.e. I’d like:
@named R = [Resistor(R=n) for n in 1:10]
to create a vector of Resistors with resistances 1 to 10. These could be named e.g. R_1…R_10
It’s not difficult to achieve this but it’s a hack:
R = [Resistor(name=Symbol(:R_, n), R=n) for n in 1:10]
What do you think?
I think it’s not too difficult to achieve with Julia’s macros.
The hack seems fine. The name field is exposed to take in symbols so that people can programmatically name things. I personally think such a macro extension would be overkill, but no reason to not make one.
There is this syntax for creating several similar components
@named R 1:10 i -> Resistor(R=i)
it’s described in the docstring for @named, which also mentions that it’s not recommended to use it 
Didn’t know that…
Seems that creating identical components is fine, though:
julia> @named y[1:3] = foo(x)
3-element Vector{NamedTuple{(:i, :name), Tuple{Int64, Symbol}}}:
(i = 41, name = :y_1)
(i = 41, name = :y_2)
(i = 41, name = :y_3)
But as you say:
@named y 1:10 i -> foo(x*i) # This is not recommended
What’s the issue with this form?
Maybe @YingboMa knows
It’s just kind of a hack given how the @named macro is implemented. It’s kind of surprising it works, since it just grabs the args at the highest level and slaps name = $y in there.
