Multiple aggregates in a single pass, using Purescript
-- This is based on ideas from the excellent article "Beautiful Aggregations
-- with Haskell" by Evan Borden: https://tech.freckle.com/2017/09/22/aggregations/
module Aggregation where
import Prelude
import Data.Foldable (foldMap)
import Data.Monoid.Additive (Additive(..))
import Data.Newtype (un)
module Main where
import Data.Generic.Rep (class Generic, Argument, Constructor, Product)
import Effect (Effect)
import Effect.Class.Console as Console
import Effect.Uncurried (EffectFn1, EffectFn2, EffectFn3, runEffectFn1, runEffectFn2, runEffectFn3)
import Prelude (Unit, bind, discard, (>>=))
import Type.Data.Peano.Nat (class IsNat, NProxy, Succ, Z, d0, reflectNat, kind Nat)
-- Any product data type with a Generic instance can be made mutable!

The CouchDB replicator database

1. Introduction to the replicator database

A database where you PUT/POST documents to trigger replications and you DELETE to cancel ongoing replications. These documents have exactly the same content as the JSON objects we used to POST to /_replicate/ (fields "source", "target", "create_target", "continuous", "doc_ids", "filter", "query_params".

Replication documents can have a user defined "_id". Design documents (and _local documents) added to the replicator database are ignored.

The default name of this database is _replicator. The name can be changed in the .ini configuration, section [replicator], parameter db.

2. Basics

Monads and delimited control are very closely related, so it isn’t too hard to understand them in terms of one another. From a monadic point of view, the big idea is that if you have the computation m >>= f, then f is m’s continuation. It’s the function that is called with m’s result to continue execution after m returns.

If you have a long chain of binds, the continuation is just the composition of all of them. So, for example, if you have

m >>= f >>= g >>= h

then the continuation of m is f >=> g >=> h. Likewise, the continuation of m >>= f is g >=> h.
