I'm missing something..

Okay, I was trying to convert a string into a table and it just will not work! Here's the code:

function filereadline(file, line)
if fs.isDir("/"..file) == false then
if fs.exists("/"..file) == true then
file = fs.open("/"..file, "r")
whole = file:readAll()
file:close()
whole = textutils.unserialize(whole)
if whole[line] == nil then				    -- This is true even if it really isnt
return nil
else
lineOfWhole = whole[line]
return lineOfWhole
end
else
return nil
end
else
return nil
end
end

Ok I'm not seeing any issues here with this code. Is the contents of the file been written in the format that textutils.serialize writes it in?

SLIGHTLY OFF TOPIC:
you have some redundant logic in there. below is the exact same logic as yours, just some refined logic :)/>

function fileReadLine( file, line)
  file = "/"..file
  if fs.exists( file ) and not fs.isDir( file ) then
    local file = fs.open( file, "r" )
    whole = textutils.unserialize( file:readAll() )
    file:close()
    return whole[line]
  end
  return nil
end

No, I wrote the lines myself in the file, is it any different when you write it in the program?


Yeah, I guessed it could be shortened alot, I kinda made it in a few minutes, so no time to think about it really. :P/>

yeh it is a little different synatx. the whole thing is normally on one line, and all surrounded in { } other than that its pretty much the same as writing it in the program…

example:
{[1]="This",[2]="is",[3]="an",[4]="example",}

Ohh.. I'm so stupid.. but lemme ask you this.. if you wanted to convert a regular file's text into a table, how exactly would you do so?

Well it varies… what kind of data is in the file and how does it need to be stored in the table? is the files contents always in a similar format?

Here's what I'm trying to say here. Say there's a regular executable program and I need to read the first line of it for some weirdo reason, how would I read that first line? (Or any line)

you can use readLine, however this can be a bad way sometimes when trying to read a line far down, say if something happens to the program and the file handler stays open. I tend to open the file, read all contents of the file, close the file and then split the string into a table by the new line character "\n" … if you don't know how to write a spilt function I'm sure there are several through the API section…. there is also one in a link in my signature…
