The Monadologie Wiki

Monadologie, the library, brings the power of monad comprehensions to Groovy programming.

Building

Check the README file for instructions on how to build the library.

Documentation

• What makes monad a monad and how to make one?
• Monad laws
• Expanding comprehensions
• Examples of usage:
  • Collections
  • Option
  • Either
  • Reader
  • Writer
  • State
• Monoids
• Gotchas! Worth checking out if you’re to use Monadologie

Future development

Some of the areas of future investigation and development include:

• MonadPlus
• expanding foreach expressions using AST transformations
• new syntax, e.g. a <- [1, 2, 3], instead of a = takeFrom {[1, 2, 3]}
• monad transformers
