The Vis Design Lab website is based on the Caleydo website and built with Jekyll.

Here is a good cheat sheet: https://gist.github.com/smutnyleszek/9803727

If you have Ruby on your machine, just install Jekyll and a plugin:

$ gem install jekyll
$ gem install jekyll-redirect-from

Further details on installing Jekyll and its requirements: https://jekyllrb.com/docs/installation/

$ jekyll serve -i

Running Jekyll in incremental (-i) mode is significantly faster.

$ open http://0.0.0.0:4000/

All VDL members are responsible for updating their content regularly. Small changes that you have tested thoroughly using Jekyll may be pushed to main, but we recommend using separate branches to submit pull requests for additional review and to catch mistakes. See the resources below for details on the following:

• Adding team members
• Adding publications
• Adding images

You can create a branch and add/edit files from the GitHub site. Alternatively, you can write your changes from the command line (below), and go to GitHub to create a pull request from that branch.

$ git checkout -b new-branch-name
$ git commit -am "make your changes and commit them"
$ git push origin new-branch-name

Jekyll generates websites for you based on data stored in _config.yaml. One important aspect is a "collection", such as publications, which get rendered using specific layout templates to designated pages. For example, a single publication gets its own webpage (/publications/id/), and it gets added to the list of all publications as well (/publications/). Content for Jekyll can be written in Markdown for automatic parsing, and variables stored in YAML at the top of both Markdown and HTML pages. Check the Jekyll and Liquid template syntax documentation for further details.

The CSS is built using SASS along with several SASS tools: Bourbon, Neat, and Bitters. SASS provides imports, variables, mixins (functions), and nested CSS so you can write better stylesheets. The additional tools provide grid layouts, vendor prefixing, and preset styles, and they are preloaded into the repository.

You can modify the CSS or SASS directly, since Jekyll builds it for you. The main site SASS file is in css/site.scss, which imports all other files, including the SASS tools in the _sass directory.

Unfortunately, changes to the code have been made throughout the SASS tools, so the SASS tools should not be upgraded. In the future, I would recommend rewriting the stylesheets (from scratch or through the Jekyll-compiled output CSS) so that you just use SASS and more modern CSS3 features like media queries and variables.

Installation instructions above for Jekyll will work for the most part, but you can also emulate the current GitHub Pages server environment with the following installation instructions: https://help.github.com/articles/setting-up-your-github-pages-site-locally-with-jekyll/

To install the GitHub Pages gem, you may need to install the Ruby DevKit for your operating system.
