date calculated with currentdate plus n days
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? juh

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 -- http://www.ousia.tk

Thanks! I thought it should be possible with lua, but I found no entry point to use lua in context by defining new commands. juh
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 On 14/08/18 05:37, Jan U.

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 -- http://www.ousia.tk

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 help,
Pablo

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 -- http://www.ousia.tk

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. ;-) juh

It already exists: - Database module http://wiki.contextgarden.net/M-database - handlecsv module https://modules.contextgarden.net/cgi-bin/module.cgi/ruid=55907888/action=vi...
