I'm trying to get the Magento Documentation in a format which I can use in Dash. An article on the Dash website describes how to import a number of types of documentation into the required format, unfortunately phpdoc is not one of them.
Does anyone have any suggestions of how I can achieve this?
I'm the developer behind Dash. Currently there is no phpdoc to docset generation script, so you're stuck with creating one yourself I'm afraid.
However, I do recommend taking the easy way out, which is generating the docset based on the PHP source using doxygen (see "Creating Docsets using Doxygen" inside the article you linked). If you need help, feel free to contact me.
