Apache® DataSketches™ Website

This is the DataSketches website source. Please visit the main DataSketches website for more information.

If you are interested in making contributions to this site please see our Community page for how to contact us.

How the website works

  • The website is published directly from a specially named asf-site branch. The content of this branch is generated automatically by Jekyll from the master branch whenever changes are detected in the master branch. One should never modify the content of the asf-site directly.

  • The master branch consists primarily of GitHub compatible MarkDown documents, which hold all the written content.

  • There are two navigation mechanisms on the site to help the user find documents: the nav_bar at the top of each page and the table-of-contents toc drop-down menus on the left of each page. Individual pages can link to each other using standard MarkDown links.

How to contribute content to the website

In order to contribute changes to the website content, you will need to fork this repository to your own GitHub profile.

If you only need to change an existing page, edit the relevant MarkDown page locally and submit a pull-request to master.

However, if you need to add a new page to the website, you may need to modify the toc to enable users to find it:

  • Create the new MarkDown document with the appropriate layout definition, and copyright notice. This can be copied from any of the existing pages. The types of available layouts can be found in the /_layouts/ directory. Almost all site documents use the doc_page layout. Place the new page in an appropriate subdirectory in master.

  • The toc is generated statically by the developer/author, when it needs to be updated, by running a small Java program called TocGenerator.java located in /src/main/java/org/datasketches/docgen/. The TocGenerator takes input from the /src/main/resources/docgen/toc.json file and save the output html in /_includes/toc.html in master. Please do not edit the toc.html file directly.

  • The toc.json file is pretty easy to figure out. It is a tree structure of two types of elements, Dropdown and Doc. Each element has 4 or 5 key:value pairs. Make sure you structure the JSON correctly with matching braces and brackets, and with commas between tree elements.

  • Run the table of contents generator. The runTocGenerator method is a static member of TocGenerator.java. You can run this from your preferred IDE or from the command line. You should see the genenerated HTML as output to the console.

  • Once you have run the generator, ensure that your new entry is included in the toc.html file under the _includes subdirectory.

  • If you have Jekyll installed on your computer you can visually check the toc for proper operation before submitting your PR.

  • Lastly, submit your pull request for review!
