Reverse Line Reader 
===========

Asynchronous reverse line-by-line file reader. This started as a fork of Nick Ewing's line-reader. Major parts are rewritten to read the file from bottom to top, but the api works more or less the same.

Install
-------

npm install reverse-line-reader

Usage
-----

The eachLine function reads each line of the given file. Upon each new line,
the given callback function is called with two parameters: the line read and a
boolean value specifying whether the line read was the last line of the file (on the top of the file).
If the callback returns false, reading will stop.

var lineReader = require('reverse-line-reader');

lineReader.eachLine('file.txt', function(line, last) {
console.log(line);

if (/ done /) {
return false; // stop reading
}
});

eachLine can also be used in an asynchronous manner by providing a third
callback parameter like so:

var lineReader = require('reverse-line-reader');

lineReader.eachLine('file.txt', function(line, last, cb) {
console.log(line);

if (/ done /) {
cb(false); // stop reading
} else {
cb();
}
});

The eachLine function also returns an object with one property, then. If a
callback is provided to then, it will be called once all lines have been read.

var lineReader = require('reverse-line-reader');

// read all lines:
lineReader.eachLine('file.txt', function(line) {
console.log(line);
}).then(function () {
console.log("I'm done!!");
});
