ghc-validation 1.1.2
Dependencies: ghc-assoc@1.0.2 ghc-semigroups@0.20 ghc-semigroupoids@5.3.7 ghc-bifunctors@5.5.15 ghc-lens@5.1.1
Channel: guix
Location: gnu/packages/haskell-xyz.scm (gnu packages haskell-xyz)
Home page: https://github.com/qfpl/validation
Licenses: Modified BSD
Synopsis: Data-type like Either but with an accumulating Applicative
Description:

A data-type like Either but with differing properties and type-class instances.

Library support is provided for this different representation, including lens-related functions for converting between each and abstracting over their similarities.

The Validation data type is isomorphic to Either, but has an instance of Applicative that accumulates on the error side. That is to say, if two (or more) errors are encountered, they are appended using a Semigroup operation.

As a consequence of this Applicative instance, there is no corresponding Bind or Monad instance. Validation is an example of, "An applicative functor that is not a monad."

Synopsis: Higher-order functional reactive programming
Description:

This library lets you write interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse. Reflex is a fully-deterministic, higher-order FRP interface and an engine that efficiently implements that interface.
