Matthias Noback has continued his series looking at using Sculpin to create static pages for "in-project documentation" with this second post focusing more on the creation of "virtual pages". These pages allow the insertion of dynamic content into pages pulled from other sources (in this case, from the source of the project).

Previously we looked at how to use the static site generator Sculpin to generate in-project documentation. When Sculpin builds the HTML files and assets it looks at what files are in the source/ directory and processes them based on certain rules (e.g. "parse Markdown files", "format HTML files with Twig", etc.). The purpose for my "living documentation" project is to also dynamically generate documentation based on PHP and configuration files from the main project.

[...] The Sculpin documentation mentions several ways to generate dynamic content for a static site, as opposed to the standard way of adding static Markdown or HTML files. [...] So, I dug into the source code of Sculpin to find out what would be a reasonable extension point. It turned out that the best way to approach this was to create a custom data source (which is currently not documented).

He then walks you through the creation of a custom data source with "dataSourceId" and "refresh" methods the tool uses to pull in the dynamic data. He shows how to set up the script to be called at any time and have the same effect (Sculpin does this when the "server" is running) and defining the service in your Sculpin configuration.
