Lean prover community website

The deployed website lives on the master branch of this repository. To make changes to the website, please make a PR against the lean4 branch. Once your PR is merged, CI will automatically deploy the changes to the master branch.

Dependencies

• pip install -r requirements.txt

Building the bibliography requires bibtool.

In order to rebuild the CSS from SCSS, you also need:

• sass
• bootstrap should be unpacked at the project root

The website relies on several components which are built in other repositories:

• mathlib_stats
• lean4web
• mathlib4_docs (built by CI in doc-gen4)

Building

• Build CSS if needed: sass scss/lean.scss > css/lean.css
• Build site using make_site.py. Use option --local for local viewing (internal url will be prefixed by local file path). Use option --reload to continuously build when templates are changed (this won't work for watching changes in data/).

If you want to retrieve the list of Zulip users to get the users map, the environment variable ZULIP_KEY should be set with the Zulip API key of the map scraper bot.

If you want to work on a new feature, there are several helpful tricks to know.

First you will very quickly hit the GitHub API rate limit without authentication. You can create a personal access token and run GITHUB_TOKEN=my_token_copied_from_github ./make_site --local during your experiments.

You can also run the script once normally and then run NODOWNLOAD=1 ./make_site --local to build the website using the information previously downloaded. This information is stored into the data_cache folder. If you need the script to download something but not everything you can temporarily change the relevant if DOWNLOAD: into a if not DOWNLOAD:.

You can also choose to render only certain templates using ./make_site --local --only my_template.html. This argument can actually be a regular expression, but giving one template name is the most common use case.

TODO

• Better integration with API docs
• Use webpack or similar to bundle all the javascript?
