Hi all,
I want to insert a due date for payments in my invoice and I would like
to calculate it from \currentdate. Something like
define \duedate = \currentdate plus 10 days
Is this possible?

Hi Jan-Ulrich,
if you don’t mind using Lua, here you have it:
\starttext
\def\duedate{\cldcontext{os.date('\letterpercent d/\letterpercent
m/\letterpercent Y', os.time()+ 10 * 24 * 3600)}}
\duedate
\stoptext
Just in case it helps,
Pablo

Thanks!
I thought it should be possible with lua, but I found no entry point to
use lua in context by defining new commands.

On top of that I recommend to use context.date to get the correct
formatting according to the current language options:
\starttext
\def\duedate{\ctxlua{
local t = os.date('*t', os.time()+ 10 * 24 * 3600)
context.date{ d = t.day, m = t.month, y = t.year }
}}
\duedate
\stoptext

Many thanks for your reply, Henri.
Where are those context.* Lua commands documented?
I want to generate an xtable using Lua code, but I don’t know where to read.
Many thanks for your help,
Pablo

They aren't documented because they are just the context commands. You
can read more about how it works in
http://www.pragma-ade.nl/general/manuals/cld-mkiv.pdf
Here a little sample with an xtable:
\starttext
\startluacode
local function duedate()
local t = os.date('*t', os.time()+ 10 * 24 * 3600)
context.date{ d = t.day, m = t.month, y = t.year }
end
context.startxtable{frame = "off"}
context.NC() context("Note") context.NC() context("Date") context.NR()
context.NC() context("Hand in before") context.NC() duedate()
context.NR()
context.stopxtable()
\stopluacode
\stoptext

Many thanks for your reply, Henri.
I remember paging through the manual, it’s included in the distribution.
I rewrote your sample as (xtables are the only tables I know in ConTeXt):
\starttext
\startlua
context.startxtable()
context.startxrow()
context.startxcell()
context("Note 1")
context.stopxcell()
context.startxcell()
context("Note 2")
context.stopxcell()
context.stopxrow()
context.startxrow()
context.startxcell()
context("Note 3")
context.stopxcell()
context.startxcell()
context("Note 4")
context.stopxcell()
context.stopxrow()
context.stopxtable()
\stoplua
\stoptext
Many thanks for your help,
Pablo

Seeing this example I wonder if there is already an example taking a
csv-file and creating a table based on its content. I guess building
blocks are readfile, loops and setting the stop sign (; oder ,).
As I know a bit of Python, at least, I might be able to search for the
building blocks in the doku. ;-)
