Akh

Javascript Monad and Monad Transformer Collection

Overview

Collection of simple monad and monad transformers that implement Fantasy Land's interfaces.

Library

Monad Transformers

• IdentityT - akh::trans::identity - Transforms a monad to itself. (Monad, Functor, Applicative Functor)
• StateT - akh::trans::state - State transformer. (Monad, Monoid, Functor, Applicative Functor)
• ListT - akh::trans::list - List transformer. (Monad, Monoid, Functor, Applicative Functor)
• ContT - akh::trans::cont - Continuation transformer. (Monad, Functor, Applicative Functor)
• DContT - akh::trans::dcont - Delimited continuation transformer. (Monad, Functor, Applicative Functor)
• EitherT - akh::trans::either - Either transformer. (Monad, Monoid, Functor, Applicative Functor)
• ErrorT - akh::trans::error - Error transformer. (Monad, Monoid, Functor, Applicative Functor)

Monads

• Identity - akh::identity - Identity computation. (Monad, Functor, Applicative Functor)
• State - akh::state - Stateful computation. (Monad, Functor, Applicative Functor)
• List - akh::list - List computation. (Monad, Monoid, Functor, Applicative Functor)
• Cont - akh::cont - Continuation computation. (Monad, Functor, Applicative Functor)
• DCont - akh::dcont - Delimited continuation computation. (Monad, Functor, Applicative Functor)
• EitherT - akh::either - Either computation. (Monad, Functor, Applicative Functor)
• ErrorT - akh::error - Error computation. (Monad, Functor, Applicative Functor)
• Trampoline - akh::trampoline Trampolined computation (Monad, Functor, Applicative Functor)

Code

Akh is written in Khepri. Khepri is an ECMAScript derived language focused on functional programming that compiles to Javascript. Khepri sources are in lib directory with node output in dist_node and AMD output in dist.

# Compile all Khepri files
$ npm run build

# Run tests
$ npm test

# While developing, auto compile changed files
$ ./node_modules/.bin/khepri -w lib -o dist_node --package_manager=node

Changelog

0.6.0 - March 23, 2014

• Added IdentityT to transform a monad to itself.
• Added Trampoline monad.
• More work on call stack.
