Hi Markus,
I think you might want something like:
-- untested code
function my_xpcall (f, ...)
local result = xpcall (function () return f(unpack(arg)) end,
function (msg)
-- build the error message
return msg..'\n'..debug.traceback()..'\n'..os.date()
end)
if not result[1] then
-- throw an error
end
-- remove status code
table.remove (result, 1)
return unpack (result)
end
You can modify it to return the status code (a boolean) or to add
more info to the error message...
I hope it will clarify the mechanism,
Tomas
