The Vulkan API Specification and related tools

Vulkan^® API Documentation Project

This repository contains formal documentation of the Vulkan API. This includes the main API Specification, the reference (man) pages, the XML API Registry, and related tools and scripts.

Single-Branch Model

As of the 1.0.25 release, we have switched to a new "single-branch" model in which all extensions are included in the source of the 1.0 branch of the Specification, and can be configured in or out of the build using Makefile options.

Building the Specification and Reference Pages

As of the 1.0.40 release, we have moved from the old asciidoc toolchain to a new one based on asciidoctor. See doc/specs/vulkan/README.adoc for more information on installing the toolchain and building the Specification.

Generating Headers and Related Files

The header file (src/vulkan/vulkan.h) and many parts of the specification and reference page documents are generated from descriptions in the XML API Registry (src/spec/vk.xml). The generated files, with the exception of vulkan.h, are not checked into the repository. If you change vk.xml, you can regenerate the header by going to src/spec and running:

$ make clobber install

The other generated files are built as required via dependencies in doc/specs/vulkan/Makefile .

vulkan-docs's Issues

Basic checking of data types.

Update registry to provide basic checking of data types for attributes and elements. For example, a text attribute that is used for a C identifier should use a regex to verify that it is a C identifier.
