A collection of scripts originally written for CSE 13S. Oversees everything from GitLab course group creation, student repository creation, all the way to cloning repos and adding users to a shared resources repository.

To install the included scripts, run:

./install --all

To install the scripts and man pages for development, run:

./install --symlink

To uninstall the scripts, run:

./uninstall.sh

A brief description of the provided scripts/utilities:

• addtorepos - adds students to a set of specified repositories.
• checkout - checks out cloned student repositories to commit IDs submitted for a specific assignment.
• clone - clones student repositories.
• createrepos - creates course GitLab course and student repos.
• pushfiles - adds files to cloned student repositories, pushing the changes.
• rmfiles - removes files from cloned student repositories, pushing the changes.
• rmfromrepos - removes students from a set of specified repositories
• roster - scrapes Canvas for a CSV of the student roster.

Read the supplied man pages for more information on each of these utilities.

To get (arguably) the full experience of these utilities, you should add the installed scripts directory to your $PATH and the installed man page directory to your $MANPATH.

To add the scripts directory:

export PATH=$PATH:$HOME/.config/gcu/scripts

To add the man directory (the double colon is intentional):

export MANPATH=::$MANPATH:$HOME/.config/gcu/man

You may want to add these exports to your shell configuration files.

Running the installation script will add a template configuration file under the following path:

vi $HOME/.config/gcu/config.toml

The template configuration file should be copied, modified, and used on a per-course basis. It is recommended to have a directory of configuration files if you have multiple courses to manage. A valid configuration file contains the following fields:

canvas_url = "https://canvas.ucsc.edu"
canvas_course_id = 42878
canvas_token = "<your token here>"
base_repo_path = "cse13s/winter2023/section01"
gitlab_server = "https://git.ucsc.edu"
gitlab_token = "<your token here>"
template_repo = "https://git.ucsc.edu/euchou/cse13s-template.git"

• canvas_url: the Canvas server that your course is hosted on.
• canvas_course_id: the Canvas course ID for your course. The one in the template is for the Spring 2021 offering of CSE 13S. You can find any course ID directly from the course page's url on Canvas.
• canvas_token: your Canvas access token as a string. To generate a Canvas token, head to your account settings on Canvas. There will be a button to create a new access token under the section titled Approved Integrations. Note that you must have at least TA-level privilege under the course you want to use these scripts with.
• base_repo_path: the base repo path that student repos should be created under. The first component of the path should generally be the course, and subsequent components are the nested subgroups. An example of a base repo path without a section subgroup: cse13s/winter2023.
• gitlab_server: the GitLab server that you want to create the course group and student repos on.
• gitlab_token: your GitLab token as a string. You can create a GitLab token by heading to your account preferences, clicking on the access tokens tab on the left, and creating a token with the API scope enabled.
• template_repo: the template repository to import and use as a base for student repositories. Note that this template repository will need to be publically visible and must be supplied an HTTP URL, not SSH.

To specify which config to use, simply set a GCU_CONFIG environment variable before running any of the provided scripts/utilities. The following example command pipelines only have GCU_CONFIG set for the respective pipeline so as to not pollute the environment variable namespace, but using export and/or env are viable approaches as well. Having GCU_CONFIG set per command pipeline is handy if you happen to be managing several classes concurrently.

GCU_CONFIG=<path to config> bash -c "roster | createrepos | addtorepos <resource repo id>"

GCU_CONFIG=<path to config> bash -c "roster | clone | checkout --asgn=5"
