How to get global variable in resumed function.

[wisdom1972]

Describe the feature you'd like to have

• for support team, we can simulate the Human resource, but I want to get the charge for every service.
• support engineer is resource, we must request, and release after the function occupy the resource.
• in the function. we want to record what is our charge, for traffic charge, airline charge.

If possible, sketch out an implementation strategy

Can you describe what you have tried and potentially what issues you are getting? A minimal example will be pretty helpful.

There is also the standard non-answer as well -- do not use global variables, they are evil ;)

[Krastanov]

Here is a quick generic example (basically you can use a global like in a usual function)

julia> using ResumableFunctions

julia> const mygloblist = [];

julia> @resumable function f()
           while true
               a = length(mygloblist)
               push!(mygloblist, a)
               @yield a
               a > 10 && break
           end
       end
f (generic function with 1 method)

julia> collect(f())
12-element Vector{Any}:
  0
  1
  2
  3
  4
