Convert PO files to Javascript objects or JSON strings. The result is Jed-compatible.

## Getting Started
Install the module with: `npm install po2json`

### As a library
var po2json = require('po2json');

### As an executable
po2json translation.po translation.json

## Documentation

### Methods

po2json has 3 methods, all of which take exactly the same options. The main function is `parse` which actually does the parsing to JSON. The 2 others - `parseFile` and `parseFileSync` are convinience functions to directly read PO data from a file and convert it to JSON.

Parse a PO buffer to JSON

* `po2json.parse(buf[, options])`
	* `buf` - a _po_ file as a Buffer or an unicode string.
	* `options` - an optional object with the following possible parameters:
		* `fuzzy` Whether to include fuzzt translation in JSON or not. Should be either 		`true` or `false`. Defaults to `false`.
		* `stringify` If `true`, returns a JSON string. Otherwise returns a plain 		Javascript object. Defaults to `false`.
		* `pretty` If `true`, the resulting JSON string will be pretty-printed. Has no 		effect when `stringify` is `false`. Defaults to `false`
    * `format` - either `raw` or `jed`. `raw` produces a "raw" JSON output, while `jed` produces an output that is 100% compatible with Jed. Defaults to `raw`
    * `domain` - the domain the messages will be wrapped inside. Only has effect if `format: 'jed'`.

Parse a PO file to JSON

* `po2json.parseFile(fileName[,options], cb)`
	* `fileName` - path to the po file
	* `options` - same as for `po2json.parse`
	* `cb` - a function that receives 2 arguments: `err` and `jsonData`

Parse a PO file to JSON (synchronous)

* `po2json.parseFileSync(fileName[, options])`
	* `fileName` - path to the po file
	* `options` - same as for `po2json.parse`

## Examples

### Basic usage with PO data as a buffer/string
var po2json = require('po2json'),
    fs = require('fs');
fs.readFile('messages.po', function (err, buffer) {
  var jsonData = po2json.parse(buffer);
  // do something interesting ...

### Parse a PO file directly - Asynchronous Usage
var po2json = require('po2json');
po2json.parseFile('messages.po', function (err, jsonData) {
    // do something interesting ...

### Parse a PO file directly - Synchronous Usage
var po2json = require('po2json');
var jsonData = '';
try {
    jsonData = po2json.parseFileSync('messages.po');
    // do something interesting ...
} catch (e) {}

### Parse a PO file to Jed format
var po2json = require('po2json'),
    Jed = require('jed');
po2json.parseFile('messages.po', { format: 'jed' }, function (err, jsonData) {
    var i18n = new Jed( jsonData );
