Loading Tables from Files

This page (http://computercraft.info/wiki/Tables#Saving_Tables_to_Files) is incorrect, at least in CC1.6. It states this line:

local data = file.readAll()

which gives me a 'nil' error. It should be this:

local data = file.read()

At least, as far as I know.

nope. readAll is fine.
I'm going to assume the error message is attempt to index ? (a nil value)
which means the file you're trying to read doesn't exist.

One of the things I found out with CC1.6+ If you try the following:

local file = fs.open("data", "r")
local file = file.readAll()

Will error saying attempt to index global and moan at you!

If you take away the local bit so it looks like this:

file = fs.open("data", "r")
file = file.readAll()

It should work! Well it did when I just tested it!

That's strange. I use 'local file = fs.open("fileName","r")' in CC1.6 without problems. Sounds like something else is going on there, DannySMc.

yeh as Dog said, you've definitely got something wrong somewhere else, removing local is never a solution, and the first code — although it has a redundant `local` — works perfectly fine.

local file = fs.open("data", 'r')
file = file.readAll() --# its still local here, 'cause you defined it local above

Ahh fair enough, I have no idea then >.<
