scan:11: attempt to index? (a nil value)
wat is wrong

[Kingdaro]

data = f:read("*a")

Should be:

data = f.readAll()

EDIT: No, the error here is that f doesn't exist. Should probably check if f isn't nil first before reading it.

Works fine for me, but I do see a problem arising from your ReadDir function because you're calling ReadDir within itself if dataein[i] is a folder. Remove that just to check if it works.

No f:read("*a") is the way for io. readAll() is for fs

When removing that just nothing happens ~_~ It prints nothing

[remiX]

I removed only that line and it works fine for me... Check the attachment

[svdragster]

Woah, thanks.

Edit: Well I wanted it to check all the directories, but without that I don't know a different way to check all dirs for program. Anyone knows how?

[remiX]

Is yours working yet?

I think the problem is that fs.list returns a list of the file names inside a directory, so when using io.open you pass the name of the file, instead of the full path.
this should work:

function ReadDir(dir)
 local dateien = fs.list(dir)
 for i = 1, #dateien do
  local path = fs.combine(dir, dateien[i])
  if fs.isDir(path) then
    ReadDir(path)
  end
  check(path)
 end
end

Now it stops at rom/apis/colors, with the error message: "scan:22: Expected number"

[MysticT]

There's no lightgreen color:

term.setTextColour(colors.lightgreen)

It should be:

term.setTextColour(colors.lime)
