MIOGUI

More Immediate Operation GUI - Develop GUI in scheme in incremental & immediate mode!

Alpha version! Need some cleanup and some more widgets & demos...

Concepts

Immediate Mode GUI

This means that the user never has to deal with objects (anti-oop way ;).

Some projects, written in C or C++

• dear imgui
• Sol on Immediate Mode GUIs
• IMGUI
• Zero Memory Widget

A Microsoft paper on the subject:

• It’s Alive! Continuous Feedback in UI Programming

Cascading Stylesheets

• Based on CSS

• Basic box model things, TODO: document supported attributes and selectors

• Transitions ;)

Scheme

• Simple but powerful language
• REPL (Read Eval Print Loop) means you don't need to restart the program for seeing changes on your program.
• We actually support chez scheme but it's possible to port to others schemes

Network REPL

• Nanomsg library allows to connect at any moment from anywhere to the runtime to modify the code on the fly without loosing state.

Cairo

• Nice graphics with simple and powerful API
• We could port the thing to opengl, GDI+, Xcb if needed

SDL2

• Powerful and portable abstraction for handling video and input and much more
• Could be replaced with some other system like Xcb, Win32 API, etc
• Why not send the frame to a web client and handle the ui with javascript. This could be done with cairo rendering an svg or sending directy some html.

Get & Install

You'll need chez scheme 9.4 and thunderchez Required also nanomsg-1.0, sdl-2.0.4, cairo

Checkout: You'll need fossil

fossil clone https://pizzahack.eu/fossil/miogui miogui.fossil
mkdir miogui && cd miogui && fossil open ../miogui.fossil

You can also download the latest code as a tarball: miogui-latest.tar.gz

Remember to setup thunderchez properly.

Then run:

scheme miogui.ss

Now switch to other console and type

/path/to/thunderchez/nanomsg/remote-repl tcp://localhost:9998

From there you can modify the code. You ideally want to run that from inside emacs M-x run-scheme and send code with C-x C-e or C-c C-e
