Slides and exercises of the Lean 4 course Theorem prover lab: applications in programming languages at the Karlsruhe Institute of Technology, Summer 2022.
You can run and edit the Lean files in this repository either locally on your machine or using gitpod.io right in your browser. You can run Gitpod workspaces for free for 50 hours per month, which should be more than sufficient for the course, but you can switch to a local installation at any point.
- Register at https://gitpod.io/login/
- Go to https://gitpod.io/#/https://github.com/IPDSnelting/tba-2022/ (or click button above) to spawn a new workspace based on this repository. Whenever you click on that link again, you should get a fresh copy of the newest commit of the repository. Go to https://gitpod.io/workspaces/ instead to continue working on an existing workspace with your changes.
- When the workspace has finished loading, you should get a VS Code interface. Open the file
TBA.leanto verify the setup. - After a few more seconds, you should get a syntax-highlighted file with a "Lean Infoview" on the right that tells you the installed Lean version when placing your cursor on the last line.
- Don't forget to stop the workspace when you are done: press F1 and select "Gitpod: Stop Workspace". The workspace should stop automatically 30min after the last interaction or 3min after closing the tab, but sometimes it doesn't seem to.
- Follow the quickstart instructions up to creating the test file.
- Download this repository, either using
git cloneor the "Download ZIP" option on the green "Code" button above. - Use "File > Open Folder..." to open the repository in VS Code.
