Re: Read text file and iterate through items?

[Rob Hoelz <rob@...>]

Have you looked into io.lines?

http://www.lua.org/manual/5.1/manual.html#pdf-io.lines

for line in io.lines('myfile.txt') do
  -- do something with the line
end

Also, you're using the for loop wrong.  For iterating over each line in
a string, you'd probably use string.gmatch; for a table, try ipairs or
pairs.
