= Gitlab to Canvas syncing =
For a working example check out the [[https://gitlab.control.lth.se/regler/FRTF10|FRTF10-repo]] where as soon as any changes in pdfs are pushed to the `to_canvas` folder they are uploaded to the `from_git` folder on the [[https://canvas.education.lu.se/courses/1342/files/folder/from_git|canvas page]].

== Gitlab CI ==
Gitlab CI is run through a file called `.gitlab-ci.yml` in the root folder of the repository. This file can setup the environment we need to run certain scripts, define how and what scripts should be run and define in what cases it should be run. An example file can be found [[https://gitlab.control.lth.se/regler/canvassync/-/blob/master/gitlab-ci.yml|here]].

== Runners ==
See https://gitlab.control.lth.se/regler/<REPO>/-/settings/ci_cd, where <REPO> should be replaced with the repository name, for instructions about runners. Hopefully we will soon have some shared runners for the department, but for the moment they have to be set up for each project specifically.

== Python script ==
The [[https://gitlab.control.lth.se/regler/canvassync/-/blob/master/canvas_sync.py|current script]] uploads all files from the to_canvas folder (with subfolders) and creates the corresponding folder structure on canvas in the from_git folder.

The script assumes there exists environment variables for a canvas API token and canvas course code. A token can be added by navigating to https://gitlab.control.lth.se/regler/<REPO>/-/settings/ci_cd, where you replace <REPO> with your repository name, and looking under Variables. There you add a token with name `CANVAS_TOKEN` and one with name `CANVAS_COURSE_CODE`. 

Currently the script will upload and replace files if they already exists, but it wont otherwise delete files if they are removed from the repo.

== Canvas API Token ==
The API token can be generated in a canvas profile, and this one is generated from an account that should have access to all courses run by Automatic Control `13596~t2TYuTRlaJnfvyTznfvhDOqq7B85o2wD2jU8NBCsixzLirB8nceTFIvUzbldIa1K`.
