So I delve into the madness that is Lightroom Plugins. While they are Lua based, they are very much removed from the world of Web Engines.
The SDK only covers so much and you’d need to be aware of everything in it to get by. For instance the metadata examples don’t contain version numbers, when you need this to allow the plugin to update. Also I think (only guessing) that because I started without one, and tried updating schema, that it is need there also.
So enough bellyaching about it, and off I got to make a nice post and polish up my first plugin.
