Rederly Standalone Problem Renderer & Editor

This is a PG Renderer derived from the WeBWorK2 codebase

• https://github.com/openwebwork/WeBWorK2

DOCKER CONTAINER INSTALL

mkdir volumes
mkdir container
git clone https://github.com/openwebwork/webwork-open-problem-library volumes/webwork-open-problem-library
git clone --recursive https://github.com/rederly/renderer container/
docker build --tag renderer:1.0 ./container

docker run -d \
  --publish 3000:3000 \
  --mount type=bind,source="$(pwd)"/volumes/webwork-open-problem-library/,target=/usr/app/webwork-open-problem-library \
  renderer:1.0

If you have non-OPL content, it should be mounted as a volume at /usr/app/private.

docker run -d \
  --publish 3000:3000 \
  --mount type=bind,source="$(pwd)"/volumes/webwork-open-problem-library/,target=/usr/app/webwork-open-problem-library \
  --mount type=bind,source=/pathToYourLocalContentRoot,target=/usr/app/private \
  renderer:1.0

LOCAL INSTALL

If using a local install instead of docker:

• Dockerfile lists perl dependencies
• clone PG and webwork-open-problem-library into the provided stubs ./lib/PG and ./webwork-open-problem-library
  • git clone https://github.com/openwebwork/pg ./lib/PG
  • git clone https://github.com/openwebwork/webwork-open-problem-library ./webwork-open-problem-library
• copy render_app.conf.dist to render_app.conf
• start the app with morbo ./script/render_app or morbo -l http://localhost:3000 ./script/render_app if changing root url
• access on localhost:3000 by default or otherwise specified root url

Editor Interface

Point your browser at localhost:3000, select an output format, a problem path and a problem seed. Click on "Load" to load the problem source into the editor, and from there you can render the contents of the editor (with or without edits). Clicking on "Save" will save your edits to the specified file path.

Renderer API

Can be interfaced through /render-api

Parameters

Key	Type	Default Value	Required	Description	Notes
sourceFilePath	string	null	true if problemSource is null	The path to the file to be rendered	Can begin with Library or Contrib, in which case the renderer will automatically adjust the path from the webwork-open-problem-library root
problemSource	string	null	true if sourceFilePath is null	The source of a problem to render	base64 encoded raw pg content - can be used instead of sourceFilePath
problemSeed	number	NA	true	The seed to determine the randomization of a problem
psvn	number	123	false	used for consistent randomization between problems
formURL	string	/render-api	false	the URL for form submission
baseURL	string	/	false	the URL for relative paths
outputFormat	string (enum)	static	false	Determines how the problem should render, see below descriptions below
language	string	en	false	Language to render the problem in (if supported)
showHints	number (boolean)	1	false	Whether or not to show hints (restrictions apply)	Hint logic has some hooks into the problem source, if permission level is high enough or n number of attempts has been reached they will render if this is true (1), however if false (0) you will never see the hints)
showSolutions	number (boolean)	0	false	Whether or not to show the solutions
permissionLevel	number	0	false	Aids in the conrol of show hints, also controls display of scaffold problems (possibly more)	See the levels we use below
problemNumber	number	1	false	We don't use this
numCorrect	number	0	false	The number of correct attempts on a problem
numIncorrect	number	1000	false	the number of incorrect attempts on this problem	Relevant for triggering hints that are not immediately available
processAnswers	number (boolean)	1	false	Determines whether or not answer json is populated, and whether or not problem_result and problem_state are non-empty

Output Format

Key	Description
static	zero buttons, locked form fields (read-only)
nosubmit	zero buttons, editable (for exams, save problem state and submit all together)
single	one submit button (intended for graded content)
classic	preview + submit buttons
simple	preview + submit + show answers buttons
practice	check answers + show answers buttons

Permission level

Key	Value
student	0
prof	10
admin	20

Permission logic summary for hints and solutions

• If professor or above (permission value >= 10) you will always get hints and solutions
• If student you will get solutions if and only if we set the showSolutions flag to true
• If student you will get hints after you have exceeded the attempt threshold (if the flag is set to true)
