Simple pattern matching...

[Mike McGonagle <mjmogo@...>]

Hello All,

I guess I just don't understand why this does not work, but I have a
simple text file where each line has three chunks of data, separated
by tabs. I am using the following code to split them, but match does
not seem to return the last chunk...

for line in io.lines(filename) do
  name, register, sliders = line:match("([%S]*)[%s]*([%S]*)[%s]*([%S]*)")
  print(string.format("name = '%s' register = '%s' sliders = '%s'",
name, register, slider))
end

with the input line of:

Saxophone                       8       018763431

(obviously here the tabs were converted to spaces by the email program)

But I get the error of "bad argument #4 to 'format' (string expected,
got no value)", and the variable 'slider' is 'nil'.

Thanks,
