Maybe similar to the "spreadsheet" question:
I'm trying to use Wolfgang's letter module for my invoices and would
like to use Lua for the sums.
But I fail already at the beginning:
\startluacode
userdata = userdata or {}
userdata.invoice = userdata.invoice or { sum = 0 } -- global table for
sums
function userdata.singlesum(hours, perhour)
amount = hours * perhour
userdata.invoice.sum = userdata.invoice.sum + amount
global.context(string.gsub(string.format("\%.2f", amount), "%.", ","))
return amount
end
\stopluacode
gives:
(virtual://viafile.1 unknown preamble key [the character )] unknown
preamble key [the character )] unknown preamble key [the character )]
! LuaTeX error <main ctx instance>:1: '=' expected near '<eof>'.
system > tex > error on line 11 in file invoice.tex: LuaTeX
error ...
4 \startluacode
5 userdata = userdata or {}
6
7 userdata.invoice = userdata.invoice or { sum = 0 }
8
9 function userdata.singlesum(hours, perhour)
10 amount = hours * perhour
11 >> userdata.invoice.sum = userdata.invoice.sum + amount
12 global.context(string.gsub(string.format("\%.2f", amount),
"%.", ","))
13 return amount
14 end
I can't see what's wrong!?
I tried local and usercode, but didn’t get further.
