Hi

I'm trying to make a settings file with tables which looks like this atm:

desktop = {
  ["user"] = { username = "";
    ["Color"] = {
      ["BackgroundColor"] = colors.gray;
    };
    ["Icons"] = {
      ["Programs"] = {
        ["xMin"] = 2;
        ["yMin"] = 1;
        ["xMax"] = 10;
        ["yMax"] = 3;
        ["text"] = "Programs";
        ["Text_Color"] = colors.white;
        ["Background_Color"] = colors.black;
      };  
    };
  };
};

is it possible to read this file as a table?

Instead of trying to create a script which will write tables as strings from a file and read them back in the same manner, just use the textutils.serialize and textutils.unserialize functions available in CC.

For example, the following code writes a table to a file and reads it right back exactly as it was.

-- Our table with multiple levels.
local _table = {
    ["field0"] = 1,
    ["field1"] = {
            ["field0"] = true
        }
}

-- Write the table to a file as a string.
local fileHandle = fs.open ("file", 'w')
fileHandle.write (textutils.serialize (_table))
fileHandle.close()

-- Read the contents of the file back as a string and unserialize it into a table format.
local fileHandle   = fs.open ("file", 'r')
_table             = textutils.unserialize (fileHandle.readAll())
fileHandle.close()

For the record, this is also valid, is much less typing, and looks a little neater (in my opinion):

desktop = {
  user = { username = "";
    Color = {
      BackgroundColor = colors.gray;
    };
    Icons = {
      Programs = {
        xMin = 2;
        yMin = 1;
        xMax = 10;
        yMax = 3;
        text = "Programs";
        Text_Color = colors.white;
        Background_Color = colors.black;
      };  
    };
  };
};
