This should also work:
\starttext
\startluacode
function modification_date (file)
local f = file
local attr = lfs.attributes (f)
assert (type(attr) == "table")
if attr.mode ~= "directory" then
return os.date("%Y-%m-%d %H:%M",attr.modification)
end
end
\stopluacode
\unexpanded\def\getdate{%
\ctxlua{context(modification_date ("\jobname.tex"))}%
}
\getdate
\stoptext
I would like to do something like the following:
\getdate would return os.date("%Y-%m-%d",attr.modification)
and
\getdate{"long"} would return os.date("%Y-%m-%d
%H:%M",attr.modification)
I have looked at lua, but do not see how to do it. (Something else to
learn.)
Untested:
\def\getdate%
{\dosinglegroupempty\dogetdate}
\def\dogetdate#1%
{context{modification_date("\jobname.tex", "#1")}}
and then in the lua code
function modification_date(file, format)
....
if format == "long" then
....
else
...
end
end
