## Overview
`sofi` is an OS agnostic UI module for Python.
The main idea is to allow rapid, pythonic GUI development using standard web-based widgets from `Bootstrap` and
other common HTML5 libraries and package them in such a way that all event processing is done within python using
`websockets`.
This was developed as an exercise in poking at the underlying technologies and to see what comes out of merging them together. For a better overview of why it came to be, feel free to take a look at this post: [A Python Ate My GUI - Part 3: Implementation](http://tryexceptpass.org/article/a-python-ate-my-gui-3)
We're in a **beta** stage for now, feedback appreciated.
## Usage
The `sofi.app.Sofi` object runs the main event thread with `.start()` and provides a number of functions to help manipulate the state of the user interface, which is actually a webpage opened in a browser. The `register` and `unregister` methods provide the mechanism for subscribing to events through callbacks, while the remaining functions (`append`, `replace`, `style`, etc.) wrap the commands intended to dynamically update the widgets (which are actual HTML elements).
The commands map directly to `D3` or `jQuery` methods present in the `sofi.js` library that's loaded during initialization and is responsible for performing the requested operations.
Following basic practices from bootstrap, the widgets should be within a `Container`. The base page itself is represented with the `View` class, which wraps the necessary head, body and style tags that will contain the widgets.
Below is a quick idea of how to get things going, but check out `sample.py` for a more complicated hello world which instantiates a navbar item, adds a few links, creates some buttons, registers events and performs some timed updates.
```python
from sofi.app import Sofi
from sofi.ui import Container, Paragraph, Heading, View
import json
import asyncio
async def onload(event):
# Every page is built on top of a View object, which contains the and tags that are filled in by the other objects
v = View()
# Make a bootstrap container in which to put all your widgets
c = Container()
# Add a heading and paragraph to the container
c.addelement(Heading(2, "Dude!"))
c.addelement(Paragraph("Where's My Car?"))
# Add the container to the view
v.addelement(c)
# Tell the UI to load the HTML generated by the view
app.load(str(v))
# Instantiate the application
app = Sofi()
# Register the event handler that runs when the UI is ready to receive commands
app.register('init', onload)
# Start the app (opens the default browser) and listen for events
app.start()
```
## What do the widgets look like?
