Hello All,
I was trying to read the value of '\totalnumberofpages' into lua to do
something with it. As an example, see below.
Now, as I understand it, my example would not work as TeX gets the first go
at this and therefore the variable 'pages' is the string
'\totalnumberofpages' and not the actual value itself. And Lua cannot
process this "calculation".
I tried to go thru the manual - *cld-mkiv.pdf *- in the distro but could
not catch on how to read a metadata value (not print). I am sure that I am
missing a small trick somewhere (or is it something more involved?).
\startluacode
function myFancyCalculations(pages)
-- some fancy stuff but as an example
local myCal = tonumber(pages) + 1
return myCal
\stopluacode
\starttext
\blah
\ctxlua{context(myFancyCalculations("\\totalnumberofpages"))}
\stoptext
Thank you in advance for any tips.
best regards,
Ramkumar
