Chip - A subject registry for Gleam

Chip enables you to register a set of subjects as part of a group.

Example

We can categorize subjects in groups, then send messages to them:

import artifacts/game.{DrawCard, FireDice, PlayChip}
import chip
import gleam/list

pub type Group {
  GroupA
  GroupB
}

pub fn main() {
  let assert Ok(registry) = chip.start(chip.Unnamed)

  let assert Ok(session_a) = game.start(DrawCard)
  let assert Ok(session_b) = game.start(FireDice)
  let assert Ok(session_c) = game.start(PlayChip)

  chip.register(registry, GroupA, session_a)
  chip.register(registry, GroupB, session_b)
  chip.register(registry, GroupA, session_c)

  chip.members(registry, GroupA, 50)
  |> list.each(fn(session) { game.next(session) })
}

Previous Art

This registry takes and combines some ideas from:

• Elixir’s registry module.
• Erlang’s pg module.
• The syn global registry library.

Other Gleam registry libraries

Other registry libraries will provide different semantics and functionality:

• Singularity is designed to register a fixed number of actors, each of which may have a different message type.
