I don't use Phaser anymore and I am not tracking its development. However, I am willing to build the docset if you submit a pull request with the phaser module updated to the latest version tag.
A Dash Docset for Phaser.
The current release can index all classes, properties, and methods in the Phaser namespace.
The Phaser docset is now hosted through the Dash user contributions. You can download it in Phaser by going to Preferences > Downloads > User Contributed.
After downloading the repository, the following commands will build and compress the docset.
> ./setup.sh
> ./run.sh
