Checking for deprecated Wordpress functions

A script to help make Wordpress development a little less painful.

One of the major pains involved in Wordpress development and work (and one of the reasons why this isn’t hosted on Wordpress anymore) is that of their quickly changing API.

I’ve encountered issues where plugins have suddenly (and quietly) stopped functioning, due to a deprecated function call being removed from the Wordpress API. I’m sharing my “solution” to this issue, which is a script (which can be integrated into a CI system), which scans your plugin and/or theme code and gives you a list of the deprecated functions you’re using, as well as where they exist in your code.
