I have:
\startluacode
function modification_date(file, format)
local f = file
local attr = lfs.attributes(f)
assert (type(attr) == "table")
if attr.mode ~= "directory" then
if format == "long" then
return os.date("%Y-%m-%d %H:%M",attr.modification)
else
return os.date("%Y-%m-%d",attr.modification)
end
end
end
\stopluacode
\def\getdate%
{\dosinglegroupempty\dogetdate}
\def\dogetdate#1%
{context{modification_date("\jobname.tex", "#1")}}
This results in:
contextmodification_date("subversion.tex", "")
