Stoplight

stoplight is a tool that enables educators to easily control push access to GitHub Classroom assignment repositories.

Please note that, as of now, stoplight only supports at most 100 student repositories per GitHub Classroom assignment.

Installation

Python 3.10 required. pipx recommended.

pipx install pystoplight

Usage

Authentication

Requires a GitHub personal access token.

Once created, place in your .stoplightrc file, which you can store either in the directory where you execute stoplight or in your home directory.

token = "<TOKEN>"

Or, you can pass it in as the value of the --token option.

stoplight red --token <TOKEN>

Commands

stoplight status

To check the permissions of all student repositories for a GitHub Classroom assignment, use stoplight status.

$ stoplight status --org stoplight-demo --assignment-title assignment

Note that repositories whose names end with starter or solution or that are the assignment title are excluded.

You can also specify the organization and assignment title in your .stoplightrc.

token = "<TOKEN>"
org = "stoplight-demo"
assignment_title = "assignment"

$ stoplight status

One way to use the .stoplightrc is to store it in a directory that you use to store starter and solution files for a GitHub Classroom assignment. Then, you can use stoplight from that directory to control the push access to that GitHub Classroom assignment. A .stoplightrc in the directory from which stoplight is executed will be given priority over a .stoplightrc in your home directory.

stoplight red

To disable push access for all students to their GitHub Classroom assignment repositories, use stoplight red.

$ stoplight red

Notice that you cannot update the permissions of students who have admin access to their GitHub Classroom assignment repository. So, if you want to use stoplight, leave the following box unchecked when creating your GitHub Classroom assignment.

stoplight green

To enable push access for students to their GitHub Classroom assignment repositories, use stoplight green [STUDENTS]....

$ stoplight green Michionlion
