io.open Specific Lines

I was just wondering, is there a way to choose specific lines for it to read?

I'd say: read all and then select a line. Probably simplest way, unless - which i doubt - there is actually a way to do that with io.read().

There is no file:seek() ect in CC, you can however use file:lines() if you want to read through all the lines of a file much quicker :unsure:/>/>


for line in file:lines() do print(line) end

I don't see how i could use this to read a specific line…

You could do this:

local tFile = {}

local hHandle = fs.open("file", "r")
repeat
local line = hHandle:readLine()
table.insert(tFile, line)
until not line
hHandle:close()
print(tFile[3]) -- Gets line 3
print(tFile[10]) -- Gets line 10
