The line data objects are regular Lua tables with some specific fields defined.Reading line by line. The file handle returned by io.open has a lines member function. This function will return an iterator that can be used to retrieve every line of the file using a loop. The following code demonstrates how to read an entire file, one line at a time: file = io.open ("data.txt")lines = file:lines ()print ("Contents of file:"); Instead of entering Lua code piece by piece in the command line, you can also instruct the Lua interpreter to run a complete Lua source text file.
