The repo for hhvm.com. This contains the website, blog and HHVM/Hack documentation. You'll need PHP v5.3 or greater, and have SQLite installed.

The docs live in __docs/phpdoc/en. The .xml files and associated directories here are basically the top level outline for the documents. The key ones are language and reference.

You will update .xml files. See __docs/phpdoc/doc-base/README for instructions on how to get started. Or just look at the .xml files that already exist and copy pasta as much as you need to.

To make sure all the XML you have changed or added jives (both in legit XML and in context with the structure of the documentation), you need to run the validator.

The validator is in __docs/phpdoc/doc-base/configure.php

To run it:

php configure.php

If successful, this will update the __docs/phpdoc/doc-base/.manual.xml file that is basically all of the .xml files squashed together. This file will be used to render the .php files that will actually serve the site.

If unsuccessful, you will see errors. You can run php configure.php --enable-xml-details for more detailed XML information.

After validation, it is now time to render the docs to be served. Note that even if you have not made any changes to the documents, you must run the validation step above to generate the .manual.xml file.

In __docs/phd:

php render.php -d ../phpdoc/doc-base/.manual.xml -f php -P PHP -o ../../manual/en

The .php files will outputted to the manual/en directory.

To speed up validation, you can try something like: php render.php -d ../phpdoc/doc-base/.manual.xml -f php -P PHP -o ../../manual/en -t -p language.hack to only render topics that you changed. However, this is not really shippable yet. So before pushing, do a full validation. This is good for quick iteration.

Run a local HHVM server in the root directory, so that /manual is a top level path. Navigate to http://<your local sandbox>/manual/en.

There are some sample scripts to make this process easier:
