To build the specification document locally, clone this repository to your local system and follow the setup and build instructions. The setup and build steps make use of scripts/oneapi.py, a helper script for maintenance tasks. You can also look at the source if you want to see how to do the same task manually.

Install Python 3, Doxygen (>= 1.8.17), LaTeX, etc. To install on Ubuntu:

sudo scripts/install.sh

Create and activate a Python virtual environment with all required tools:

python scripts/oneapi.py spec-venv
source spec-venv/bin/activate

To install directly with pip:

pip install -r requirements.txt

To install on Windows:

To build the HTML document, use the following command:

python scripts/oneapi.py html

The document is organized as a book with chapters. Each element of oneAPI is its own chapter and can be built separately. For example, to build the oneVPL chapter, use the following command:

python scripts/oneapi.py html source/elements/oneVPL

To view the HTML docs, visit build/html/index.html in your browser using a file:// URL.
