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
- Have a native look and feel.
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.

Project status
Although there has not been a lot of activity in the past year, the project is still active.
I may take some time to respond to issues while I work on features I want to add to Monomer.
Useful extensions
- Hagrid, a flexible datagrid widget.
- Monomer Flatpak Example, an example of how to package Monomer applications on Linux, using Flatpak.
