Re: Need help with creating a module featuring asynchronous access of Redis

[dom96]

You should put your data into an object and then pass it around your procs. 
Don't create "global" state and capture it in closures.

Here is what I mean (probably doesn't compile, but I hope you get the idea):
    
    
    import redis, asyncdispatch
    
    type
      MyState = ref object
        db: AsyncRedis
        keystring: string
    
    proc newMyState(): MyState {.async, discardable.} =
      const
        port = 6379.Port
        domain = "127.0.0.1"
      
      return MyState(
        db: await openAsync(domain, port)
      )
    
    proc rsearch(self: MyState, pattern: string) {.async, discardable.} =
      self.keystring = repr(await db.keys(pattern))
      self.keystring.echo
    
    let state = newMyState()
    waitFor state.rsearch("test")
    
    
    Run
