sketchresponse 0.1.4

A tool for drawing and evaluating mathematical functions

SketchResponse

Note: This is a forked copy of sketchresponse/SketchResponse adapted for PrairieLearn. This library is used as the backing for the pl-sketch element.

This project (will be) published to PyPI as sketchresponse, and on NPM as @prairielearn/sketchresponse.

Warning: The API is not fully compatible with the original SketchResponse project. Additionally, the codebase has been significantly refactored, and Python 3.10 is now the minimum supported version. The information in this README is not guaranteed to be up to date.

SketchResponse is a Javascript/Python(2.7-3.x) tool for drawing and evaluating mathematical functions. It was designed for use with the edX online courseware platform. However, it is a self-contained application that can be integrated into other web platforms.

Features

• Sketch Tool - configurable Javascript front-end with plugin components to provide different function drawing and annotation capabilities. See Sketch-Tool Usage for a description of the non-configurable interface elements of the sketch tool. See Sketch-Tool Plugin Configuration for a description of the available plugins.
• Grader Library - python back-end that provides an API of function grading methods that can be composed to construct custom grading scripts. See Create a Simple Grading Script for a tutorial on building a simple grading script.

Sketch Tool Front-End

Prerequisites

You'll need to have Node.js and npm (which is now packaged with Node) to be installed on your system. Note: This currently only works with Node version 7.10.1

Installation

• Change to the sketch_tool directory:

  $ cd sketch_tool
  

• Install dependencies listed in package.json:

  $ npm ci
  

• Build a local distribution of the sketch_tool:

  $ npm run build
  

Grader Back-End

The SketchResponse grader backend has only two third party package requirements:

• flask
• numpy

Install them by running the following command in the root directory:

$ pip install -r requirements.txt

Flask is only required if you want to run a local server for convenience when implementing and testing new grading scripts. See the Tutorial Test a Grading Script on a Local Server for details.

Running tests for the Grader Library Back-end

The grader library has a collection of tests to validate the API functions. Those tests can be run from the root directory of the sketchresponse repository with the command below. If you haven't already done so, install the additional packages needed only for the unittest modules.

$ pip install -r test_requirements.txt
$ python -m unittest discover -t . test_grader_lib/

Rebuilding the documentation

As this project evolves, the current documentation will no longer match the existing codebase. Follow the instructions in HowTo Build the Docs to rebuild as needed.
