A short description of my package

PYUI(Python UI)

This project is targeted to make cross platform applications using python.PYUI is a layout pre-compiled framework for making python applications in very lightweight sizes. It uses a xml layouting system for defining layouts, python for logic and PYWebview as the renderer.Leading to a blank application size only 16MB compared to heavyweight rendering systems cosing 50+ MB or TKinter that has very legacy thread-unsafe architecture

Motivation

1.Making General Purpose Applications: This project is driven by the motivation of making a framework over python that can be used to make general purpose applications with little or no learning curve.

2.Smaller learning curve: Recent solutions for UI development mostly are hard to learn and manage. However we adopted age-old xml layouting system that makes defining UI easy for anyone with little xml/html knowlege.

3.Support of Python libaries and modules: On the logic side python can use used to it's Limit, also the threadsafe nature of the framework helps in extreme scalability.

4.Compiled Layout and Reusibility: This framework has pre-compiled layouting system.So errors in layout are identified on runtime. Also Layout supports re-usibility using PYUI Components.

Key Features of PYUI API

1. DOM Manipulation: One can change dom components from python side.There style,class,innertext and other attributes.

2. PYUI Custom Syscalls: Using this one can extend PYUI to support any JS libaries(chart.js and etc) by writing minimal Javascript.Or can use to commiunicate between JS ans Python runtime if needed without touching internal sockets.

3. PYUI Hooks: If some DOM updates are fast and can be lossy but realtime one can use PYUI Hooks.This can be mostly used to stream video or audio from Python to JS runtime

4. Window Management: A PYUI forms contain can contain more than one view(window) and PYUI provides apis to change windows dynamically. Also Exposes Webview object for PYwebview for changing the application window

5. Forms Management: PYUI provides dedicated apis to show and hide forms.

Getting Started

Setting up project

python -m PYUI.create <directory-of-project>

This will generate boilerplate project. Following folder and files will be generated in the given directory.

layout
code
layout/JS
layout/styles
code/index.py
code/__init__.py
layout/index.xml
settings.py

Compiling project

To compile to a PYUI project and run it

python -m PYUI.buildtools --compile <directory-of-project> --run

This command will compile your project into a PYUI project and run it. Within few seconds(depending on project size) you can see you layout

To compile without running project

python -m PYUI.buildtools --compile <directory-of-project>

It will save your project in build/temp_xxxxx.yyyy (see last line of buildscript output). To launch the project go to the directory and run:

python bootstrap.py

It will launch your UI

HotReloading Layouts

You can hot-reload the layout for faster UI development.

python -m PYUI.buildtools --hotreload <layout-xml-file>

Changing the xml file will reload the UI automatically

Note: Use the --keepontop flag to keep the UI on top always

For further API references for XML and PYUI check the PYUI Documentation
