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++

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:

# I recommend this limit setting because our sofware is alpha. If you run into a non-tail recursion you can lock your system :)
ulimit -Sv 1000000  
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
