Hi Hans,
Thanks for the follow-up!
I'm not sure about what the easiest approach would be, but one of the strengths
of ConTeXt is certainly the ability to "automatically" convert the same input
into different representations in the output depending on setups rather than
changing the document source.
So, ideally "time" would allow this similar to "date" to convert "16:40" into
"16:40 Uhr" or "4:40 pm" or similar. (Maybe allowing to adjust durations as
well.) The date command is quite sophisticated, I agree.
Whether formatting is handled more easily on the lua end or not, I can't really
gauge. There is in fact a great number of formatting keys available that might
be easy to parse in the context interface. So, maybe all that is needed is an
optional secondary argument "format="? I could come up with:
\startluacode
userdata = userdata or {}
function userdata.mytime(str, fmt)
local datetable = {}
for key, value in str:gmatch("(%w+)%s*=%s*(%d+)") do
datetable[key] = tonumber(value)
end
context.type(os.date("%X", os.time(datetable)))
end
\stopluacode
\def\mytime#1#2{\ctxlua{userdata.mytime([==[#1]==], [==[#2]==])}}
\mytime{year=1970, month=1, day=1, hour=0, sec=1}{}
However, I don't know how to convert/handle the different escape characters
("%") required for the format string.
Just an idea. :-)
Thank you — I'll also try the files you shared soon!
