The file is fixed width, so the second field has a lot of spaces I assume you don't want to capture?
The below works on Lua 5.1. On 5.2 you can replace the %a%d%p with %g
Thanks,
Kev
local parsed = {}
for line in io.lines() do
local num, val = line:match("^(%d+) ([%a%d%p ]+[%a%d%p])%s+$")
if num == nil then
error(string.format("Unable to parse: '%s'", line))
end
local t = {}
t.num = num
t.val = val
parsed[#parsed+1] = t
end
for i, t in ipairs(parsed) do
print(string.format("%d: '%s' '%s'", i, t.num, t.val))
end
