# Linewise

The linewise module splits a stream line-by-line with moderation of the input.

## Benefits

* An unlimited amount of text can be processed

* A line or sequence of lines can for example be scanned for patterns

* Suitable for processing logs

## Features

* Node stream interface

* Moderation of the input stream limits memory use

* Any read stream can be parsed, likewise output can be sent to any stream

# Usage

```js

var linewise = require('linewise')

var fs = require('fs')

var inStream = fs.createReadStream('/home/hugefile.log', {encoding:'utf-8'})

var parsedStream = linewise.getPerLineBuffer()

parsedStream.on('data', line)

parsedStream.on('end', end)

parsedStream.on('error', error)

inStream.pipe(parsedStream)

parsedStream.resume()

function line(text) {

	console.log(text)

}

function end() {

	console.log('End of file.')

}

function error(err) {

	throw Error(err)

}

```

# TODO

* Make it work for Windowsy Macy systems: '\r\n', '\r'
