Ubuntu Install

1. Install Ruby development environment Jekyll on Ubuntu.

2. Install Jekyll inside the Ruby environment.

   • gem install jekyll jekyll-redirect-from bundler pygments.rb
   • To do this you might need to change permissions on folders /var/lib/gems and /var/lib/gems/2.5.0.
   • The Pygments package is optional, and does require sudo permissions.

3. Install python dependencies (Optionally).

   • pip install Pygments

4. Launch the Documentation locally

   • jekyll serve -w
   • This is done from the root of the gh-pages branch of the system.
   • The serving will per default be on localhost port 4000 Link

Update API

To update the API documentation run the updateAPI.sh file. Note that you have to install both the Java and Python -doc dependencies.

Mac Install

Jekyll (and optionally Pygments) can be installed on the Mac OS in the following manner.

brew install ruby
gem install jekyll
gem install jekyll-redirect-from
gem install bundler
brew install python
pip install Pygments
gem install pygments.rb

To generate SystemDS documentation in HTML, navigate to the docs folder, the root directory of the documentation. From there, you can have Jekyll convert the markdown files to HTML. If you run in server mode, Jekyll will serve up the generated documentation by default at http://127.0.0.1:4000. Modifications to *.md files will be converted to HTML and can be viewed in a web browser.

jekyll serve -w
