Advanced Python field calculator needs documentation

Since the syntax is not standard QGIS field calculator syntax, users definitely need documentation here.
I've written down some notes
... especially that you have to put attribute names in pointy brackets is tricky.

I don't know about Victor's plans regarding it. I think it will go into plugin at some point, but first we should write docs, because for most algorithms only template file is available.
TauDEM is documented, some of the QGIS algorithms too. Not sure about others

Hi All, I spent almost a week wondering why things didn't work.
Here is my point of view, really processing should use QGIS Field calculator syntax and if possible bring it as a whole (most of GUI) so the user has the same experience across QGIS, having a different syntax adds a complexity of its own specially if it has no associated help - Sorry, no help is available for this algorithm. -
I am not to keen on using a different syntax since it makes it more difficult to work with than it should, in the mean time, can someone at least add a link to open instead of - Sorry, no help is available for this algorithm. -
