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
\startluacode userdata = userdata or {} userdata.invoice = userdata.invoice or { sum = 0 } -- global table for sums function userdata.singlesum(hours, perhour) local amount = hours * perhour userdata.invoice.sum = userdata.invoice.sum + amount context(string.gsub(string.format("%.2f",amount),"%.",",")) end \stopluacode \starttext \ctxlua{userdata.singlesum(3,4)} \stoptext Wolfgang
