Hello Taco,
Quite funny: Just 3 days ago, I wrote t-invoice.tex for my personal needs,
just 1 command and very very simple:
\startInvoice
\invoiceItem[description=Ballon eau chaude, price={5063,4 + 1115,87}]
\invoiceItem[description=Vase d'expansion, price={386,25}]
\invoiceItem[description=Plan d'implantation du bâtiment, price={257,14}]
\invoiceItem[description=Branchement d'eau, price={2891,62}]
\stopInvoice
\stopInvoice prints the total.
Here the definitions (can be enhanced and/or wikified):
\startluacode
-- namespace
thirddata = thirddata or { }
thirddata.invoices = {}
thirddata.invoices.total = 0
thirddata.invoices.pos = 1
-- get price with right format
-- p: the price
-- return price with right format
function thirddata.invoices.format(p)
local s = string.format("%.2f", p)
s = s:gsub("%.", ",")
return s
end
-- print new item
-- d: the description
-- p: the price
function thirddata.invoices.new_item(d, p)
thirddata.invoices.total = thirddata.invoices.total + p
tex.print("\\bTR\\bTD" .. string.format("%03d", thirddata.invoices.pos)
..
"\\eTD\\bTD " .. d .. "\\eTD\\bTD " ..
thirddata.invoices.format(p) .. "\\eTD\\eTR")
thirddata.invoices.pos = thirddata.invoices.pos + 1
end
\stopluacode
\def\invoiceItem{\dosingleargument\doinvoiceItem}
\def\doinvoiceItem[#1]{\getparameters[IV][#1]
\ctxlua{thirddata.invoices.new_item("\IVdescription",
\ctxlua{local s = string.gsub("\IVprice", ",", "."); tex.print(s)})}}
\def\invoiceTotal{%
\ctxlua{tex.print(thirddata.invoices.format(thirddata.invoices.total))}}
\def\startInvoice{\start
\setupTABLE[frame=off,textwidth=\textwidth,option=stretch]
\setupTABLE[r][first][bottomframe=on]
\setupTABLE[r][2,last][top=\blank]
\setupTABLE[c][first,2][align=flushleft]
\setupTABLE[c][last][align={flushright,lohi}]
\bTABLE\bTR\bTH Position \eTH\bTH Description \eTH\bTH Prix \eTH\eTR}
\def\stopInvoice{\bTR\bTD[nc=2,align=flushright]Total:\eTD
\bTD \invoiceTotal\eTD\eTR\eTABLE\stop}
Cheers, Peter
