Editing content

In order to edit the content on the website, it's important to understand how the translation and internationalization frameworks are set up. For this, we distinguish between two things:

UI language

This content is more static, such as page headings and the descriptions on the front page. This is controlled by the react-intl package, and all definitions of UI language can be found in the i18n/react-intl folder. Each language will have its own .json file in this folder, and this is where edits to the UI language should happen.

Page content

This content includes most of the content on the website such as the individual items under reference, tutorials, tools, etc. Each content type has its own setup based on where the source lives. As an example, the reference is generated from the Processing source code and has its own way of translating those generated files. The following guides explain how to change the content on the website by section.

• Download
• Documentation
  • Reference
  • Environment
  • Libraries
  • Tools
• Learn
  • Tutorials
  • Examples
  • Books
• Teach (External link)
• About
• Donate (External link)

When translating the content to a new language you need to edit the i18n/config.json file and add your language information. Then follow the instructions for each Content list (same links as above).

Writing code

• CSS: read about our stylesheets

Deploying the site

Note

The following is included in the processing-website repository for historical reasons but it is not related to the functioning of the Processing website itself. It should eventually be moved to a more suitable location.

keywords.txt

This repo contains a script updateKeywords.js that generates the keywords.txt file used for syntax highlighting in the Processing IDE.

Follow these steps in order to generate the keywords.txt file:

1. Make sure you have this processing-website repo and the processing4 repo next to each other on your computer
2. Make sure the JavaDoc and reference are up to date with the latest version of Processing. Otherwise make the necessary updates to the JavaDoc in the processing4 repo then run the Doclet script. (note: this step is only necessary if new keywords were added to the Processing API)
3. Run npm run updateKeywords

The processing4 repo now has an updated java/keywords.txt file.
