MIOGUI
More Immediate Operation GUI - Develop GUI in scheme in incremental & immediate mode!
Alpha version! Need some cleanup and some more widgets & demos...
[/doc/tip/demos/|Show me demos and screenshots!]
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:
* [https://www.microsoft.com/en-us/research/wp-content/uploads/2013/06/pldi097-burckhardt.pdf|It’s Alive! Continuous Feedback in UI Programming]
Cascading Stylesheets
* Based on [https://www.w3.org/Style/CSS/|CSS]
* CSS3 Flexbox layouts!
* CSS3 Transitions ;)
* CSS3 grid (planned)
Scheme
* Simple but powerful language
* REPL (Read Eval Print Loop) means you don't need to restart the program for seeing changes.
* 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 [http://scheme.com|chez scheme] 9.4 and [https://pizzahack.eu/fossil/thunderchez|thunderchez]
Required also [http://nanomsg.org|nanomsg-1.0], [https://libsdl.org|sdl-2.0.4], [https://www.cairographics.org|cairo]
Checkout: You'll need [https://www.fossil-scm.org|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: [https://pizzahack.eu/fossil/miogui/tarball/miogui-latest.tar.gz|miogui-latest.tar.gz]
There is a also a mirror on [https://github.com/ovenpasta/miogui|github.com]
git clone https://github.com/ovenpasta/miogui.git
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 demos/demo1.ss
# or
scheme demos/demo2.ss
...
Now switch to other console and type
/path/to/miogui/remote-repl
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
