impress. Go GUI cross-platform library

Get Started

Hello World Example contains example source code and build instructions.

Reference page is a starting point for packages documentation.

Library Overview presents basic library components.

Some usage examples are in the examples folder.

Technical details

Basic Principles of Library Design:

• Performance of the application as well as native applications.
• Facade pattern for masking complex components behind an API.
• Simple and clean application code.
• Minimal library API to follow the Go-way.
• Limited use of other libraries (graphic, low-level or native).
• Creating a GUI application without form designer or hard-coded widgets.

The main idea is to stay away from the event driven programming paradigm. See "What's wrong with event-driven programming" page.

The library uses a separate application (GTK+ 3 terminal) for drawing instead of binding low-level library to a Golang.

Project State

• The project is currently in its beta stage. It is highly suitable for the development of in-house applications.
• The project was tested on Debian 12.8 and macOS 15.1.
• While the API remains stable, please note that the specific details may be subject to change.

The project roadmap includes both short-term and long-term project stages.

A cross-platform mind-map application is being developed to showcase the core principles of the library.

Up to 2 ms from the moment you press the key, the mind-map application window is redrawn. Measured on a computer with an N200 processor without a video card.
