Thank you **andrea**.
I like your _variant_ but _match_ is for me similar in verbosity to my getText
and I think it could be compressed further.
My attempt:
import patty
variant Message:
hit(hp: int)
death(died: string)
proc hhit(m: Message) = echo "HIT " & $m.hp
proc hdeath(m: Message) = echo "DEATH" & m.died
template choose(t: typed, handlers: tuple) =
#var x = ord(t.kind)
#handlers[x]() # - compilation error: cannot evaluate at compile time
case ord(t.kind)
of 0: handlers[0](t)
of 1: handlers[1](t)
proc test() =
var h = hit(5)
choose(h, (hhit, hdeath))
test()
It works nice, but I cannot overcome problem with variable amount of handlers.
Thank you **flyx**.
When death message is dispatched entity is already removed so having ID I would
not be able to fetch name, and you will have to make string somewhere anyway to
display it - so this is not my concern.
Your solution is also very interesting.
