Flowthru.Prelude

Flowthru's FP foundations. Globally imported by every consumer via the build/Flowthru.New.Core.props file (mirrors Haskell's implicit Prelude).

Provenance

The types in this directory are inspired by and partially derived from LanguageExt v5 by Paul Louth. The upstream MIT license is preserved verbatim in LICENSE-LanguageExt.md. Source files derived from LanguageExt include an attribution header pointing to that notice.

Scope

This is not a port or fork of LanguageExt. It is a focused subset containing only the FP primitives Flowthru actively uses.

Included:

  • Eff<TRuntime, T> — capability-environment-typed effect, fails with RuntimeError
  • EffResult<T> — closed sum returned by Eff.Run
  • Has<TRuntime, TCapability> — capability constraint trait (Eff-specialised)
  • Validated<E, T> — error-accumulating applicative for pre-flight checks
  • Unit — bound type for effects with no meaningful result

Excluded (and not planned):

  • The K<F, A> higher-kinded encoding
  • Generic Functor<F> / Applicative<F> / Monad<F> typeclasses
  • Monad transformer stack (StateT, WriterT, ReaderT, RWST, …)
  • Either, Option, Try, Fin — Flowthru's RuntimeError ADT and Validated<E, T> cover these roles
  • Free monads, Pipes, Streams
  • Immutable collections (Seq, Lst, Iterable, HashMap, …)

Maintenance policy

These types are owned by Flowthru going forward. Do not chase upstream LanguageExt changes. If a behaviour or naming choice diverges from upstream, that is intentional and a Flowthru concern.

When touching files here: prefer Flowthru-internal idiom over LanguageExt fidelity. The point is not to be a faithful subset; it is to give Flowthru the FP primitives it needs without adopting a 50K-line dependency whose maintenance trajectory is uncertain.

Where the rest of the algebra lives

Some Flowthru-original types compose with the ones here but are not LanguageExt-derived and live elsewhere:

  • Flowthru.Error.RuntimeError — closed sum of runtime failure modes (the Eff failure type)
  • Flowthru.Validation.PreFlightError — closed sum of pre-flight failure modes (the Validated error accumulator's E type)

The split is deliberate: this directory contains language-level primitives; the Flowthru-specific ADTs that fill in the type parameters live with the phase they describe.
