[NTG-context] Evaluating a lua expression at the end (again)

Dear ConTeXt users, Last time, this is what I wanted, and Hans provided me an example: https://www.mail-archive.com/ntg-context@ntg.nl/msg78079.html However, the example given in that e-mail does not work with my Debian context 2016.05.17.20160523-1. Could you please help me out again? I get:

Re: [NTG-context] Evaluating a Lua expression at the end (repeat)

Hi Kumar, the function job.variables.save seems to save the key in job.variables.collected.macros instead of job.variables.collected. The problem is that macros is not created unconditionally, which is why you might run into a »attempt to index a nil value« error without some manual error

[NTG-context] Evaluating a Lua expression at the end (repeat)

Dear List, Last year, Hans helped me with this example: \starttext \startluacode local name = nil local temp = 0 function document.startwhatever(s) name = s temp = 0 end function document.addwhatever(n) temp = temp + n

[NTG-context] Evaluating a Lua expression at the end

Hi. I am trying to set up a system where I can use Lua to find a total that I can display at the end. For example, if I set a question paper, after each question, I do a \directlua{total = total + 4}, assuming this question has 4 points. At the top of my document, I now want to say Total points:

Re: [NTG-context] Evaluating a Lua expression at the end

Hello, another single-pass approach, which uses the fact that you know the questions and their point weights in advance is to form questions into a Lua table and evaluate the total first: local C = context local tab = { {Question 1, 10, }, {Question 2, 20, }, {Question 3, 30, }, }

Re: [NTG-context] Evaluating a Lua expression at the end

Hello Kumar, could you provide a (non-working) minimal example? I tried this: local C = context local n = 0 C.starttext() C(A) n = n + 1 C(B) n = n + 1 C(C) n = n + 1 print(***, n) C.stoptext() print(, n) and I got 3 (twice) - what I expected: ... ConTeXt ver:
