# tomo
|
||||
|
||||
WIP rewrite of tomo.
|
||||
[![Go Reference](https://pkg.go.dev/badge/git.tebibyte.media/tomo/tomo.svg)](https://pkg.go.dev/git.tebibyte.media/tomo/tomo)
|
||||
|
||||
This module will serve as a wafer-thin collection of interfaces and glue code so
|
||||
that plugins will be an actual viable concept.
|
||||
Tomo is a lightweight GUI toolkit written in pure Go. This repository defines
|
||||
the API that other components of the toolkit agree on. In order to use Tomo in
|
||||
an application, use [Nasin](https://git.tebibyte.media/tomo/nasin), which builds
|
||||
an application framework on top of Tomo.
