Hemlock-Berlin

Hemlock-Berlin is a hemlock extension which allows you to add a Berlin numeracy test to hemlock projects.

Installation

With the hemlock-CLI (recommended):

$ hlk install hemlock-berlin

With pip:

$ pip install hemlock-berlin

Quickstart

This example shows how to add an adaptive Berlin numeracy test to your hemlock survey and display the participant's score to him/her.

In survey.py:

from flask_login import current_user
from hemlock import Branch, Page, Label, route
from hemlock_berlin import berlin

@route('/survey')
def start():
    return Branch(
        berlin(),
        Page(
            Label(compile=display_score), 
            terminal=True
        )
    )

def display_score(label):
    label.label = '<p>Berlin score: {}</p>'.format(
        current_user.g['BerlinScore']
    )

app.py is standard from the hemlock template.

Run the app with the hemlock command line interface:

hlk serve

or with python:

python app.py
