Avoid boiler-plate when constructing a bokeh server programmatically

[mrocklin]

In https://bokeh.github.io/blog/2017/6/29/simple_bokeh_server/ we discuss making a simple bokeh server from within Python.

from bokeh.server.server import Server
from bokeh.application import Application
from bokeh.application.handlers.function import FunctionHandler
from bokeh.plotting import figure, ColumnDataSource

def make_document(doc):
    fig = figure(title='Line plot!', sizing_mode='scale_width')
    fig.line(x=[1, 2, 3], y=[1, 4, 9])

    doc.title = "Hello, world!"
    doc.add_root(fig)

apps = {'/': Application(FunctionHandler(make_document))}

server = Server(apps, port=5000)
server.start()

It might be worth thinking about how to reduce the amount of code, and in particular the number of foreign terms that a beginning user needs to understand to make this work. In my ideal world the following might work:

from bokeh.plotting import figure, ColumnDataSource, Server

def make_document(doc):
    fig = figure(title='Line plot!', sizing_mode='scale_width')
    fig.line(x=[1, 2, 3], y=[1, 4, 9])

    doc.title = "Hello, world!"
    doc.add_root(fig)

apps = {'/': make_document}

server = Server(apps, port=5000)
server.start()
