This module is long deprecated. Please do not use it anymore (was for node 0.1). I suggest you use split

this is a tiny utility function to help processing readable streams line per line with NodeJS

Here is a simple example which explains almost everything

var lines = require('lines');
var net = require('net');

net.createServer(function(socket) {
    socket.setEncoding('utf8');
    lines(socket); // here is where the magic happens
    socket.on('line', function(line) {
	  // line is one line with no trailing \n or \r
    });
}).listen('/tmp/mysock');

Lines doesn't work on non-encoded streams. Note that you can still listen to 'data' events on the same stream with no loss of data.

install it via npm

npm install lines

or get the code from the repository
