Installation

$ npm install opl-stream

Note: you will need node and npm installed first.

The easiest way to install node.js is with nave.sh by executing [sudo] ./nave.sh usemain stable

Usage

You can extract the .opl data from any stream, including stdin:

// example.js

var opl = require('opl-stream'),
    through = require('through2'),
    split = require('split');

process.stdin
  .pipe( split() )
  .pipe( opl.decodeStream() )
  .pipe( through.obj( function( obj, _, next ){
    console.error( JSON.stringify( obj ) );
    next( null, obj );
  }))
  .pipe( opl.encodeStream() )
  .pipe( process.stdout );

$> cat in.opl | node example.js 2> parsed.json 1> out.opl

$ echo -e "n204648 v37 dV c32514672 t2015-07-09T09:46:58Z i3043782 uDK_VJCS Tname=Wellington,is_in=North%20%Island%2c%%20%New%20%Zealand x174.7772239 y-41.2887639\n" | node example.js 1>/dev/null
