Pinad

Pinad is a simple python library that adds support for common Monads seen in other languages like Rust, and Haskell.

The source code is currently hosted on GitHub at: https://github.com/RobertLD/pinad

Installing Pinad

You can install Pinad through from PypI using Pip

# or PyPI
pip install pinad

Supported Monads

The pinad library currently supports the following common monads:

• Maybe - Used for values where None protection is important

and the following mondas are currently in progress:

• State - Used to maintain state across all transformations performed on a value
• Read - Used to pass implicit configuration information throughout each step in a transformation. Think OO Dependency Injection
• Write - Maintains a stateful accumulator across transformations performed on a value

Please use the issues page to suggest additional features. https://github.com/RobertLD/pinad/issues

Examples

from pinad import Maybe

def echo(v):
    return v

x = None

>>> Maybe(x).orElse(1)
Maybe(1)

Dependencies

None.

The goal of pinad is to add monad support with as few dependencies as possible
