[NTG-context] Manipulating \pagenumber with Lua code : example need

2010-09-08 Thread Vnpenguin 
Hi,
I would like to manipulate \pagenumber with Lua code, in order to add
an increment to page number, print out (\pagenumber + INC) instead of
\pagenumber.

I can't found any example in Wiki yet.

Some lines of simple code will be very appreciated :)

Thanks

You can use TeX for this, e.g.:

- \number\numexpr\userpageno+2\relax
- \number\numexpr\userpageno*2\relax
- ...
