Monomer

A cross-platform GUI library for Haskell

An easy to use, cross platform, GUI library for writing native Haskell applications.

Monomer provides a framework similar to the Elm Architecture, allowing the creation of GUIs using an extensible set of widgets with pure Haskell.

Objectives

• Be easy to learn and use.
• Be extensible with custom widgets.
• Run on Windows, Linux and macOS.
• Have good documentation.
• Have good examples.

These are not objectives for this project

Why would you want to use this library?

• You want to write your application in Haskell.
• You want to write a native, not web based, application.
