go-webkit6

WebkitGTK 6.0 bindings for go. Written with purego. Compatible with jwijenbergh/puregotk

About features

WebkitGTK is a very large library, so it is not possible for me to transfer all of its features. You can open feature request for the features you need.

Visit the functions.md to see imported functions

This library is not useful by itself, you need a GTK library.

Examples
