Subject: Learning LuaTeX : Invoice
Date: Sun, 20 Feb 2011 12:55:20 +0100	[thread overview]
Message-ID: <13F84CC8-EB65-4D8E-B2F8-54D8CBE1B32A@fiee.net> (raw)

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.
