Describe how to export downstream

[mmikhasenko]

Here is what I do in FourVectors.jl

# Access the list of function names
const ALL_GETTER_FUNCTIONS = vcat(
    collect(LorentzVectorBase.FOURMOMENTUM_GETTER_FUNCTIONS),
    collect(keys(LorentzVectorBase.FOURMOMENTUM_GETTER_ALIASSES)),
)

# Loop over each function name and import and export it
for func_sym in ALL_GETTER_FUNCTIONS
    # Import the function from LorentzVectorBase
    @eval import LorentzVectorBase: $(func_sym)
    # Export the function from this module
    @eval export $(func_sym)
end

I do not think you want to list all methods and their aliases manually.
How do you mean using @reexport ?

I think it is not a good idea to (re)export every getter function. Currently, we've decided to use short names like x,y,z,t,E,px,..., which can mess up the namespace for all packages with using FourVectors.jl.

To have a better exportability of the getter functions, we must rename them, e.g. x->x_component, so x_component can be safely exported.

The @reexport macro just grabs all exports of one package (e.g. LorentzVectorBase) and exports them again on a depending package (e.g. FourVectors.jl). However, since in the current status, LorentzVectorBase.jldoes not export the getter functions (because of the reason above),@reexport` will not help.
