Hi all, I find Parameters.jl and its function reconstruct() a very convenient way to handle models that need to be computed under many set of parameters. The feature that one can define a default value for a parameter that is a function of other parameters is really useful. However, consider the fo…

In this case if b is always a function of a I would just define it as a function using Parameters @with_kw struct Para a::Float64 end b(p) = p.a + 1 p = Para(a=1) julia> p = Para(a=1); julia> b(p) 2.0 julia> p2 = reconstruct(p, a=5); julia> b(p2) 6.0 Although I’ll grant that this might not …

Another way would be to use getproperty. (Which arguably should be used for computed fields.)

For extensive sets of parameters with precomputed quantities, I usually try to organize my code like this: struct Parameters{...} ... end struct PrecomputedModel{TP <: Parameters, ...} parameters::TP ... end function PrecomputedModel(parameters::Parameters) ... # do the precalcul…
