po2json

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 convenience 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 fuzzy 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 Defaults to raw.
      • raw produces a "raw" JSON output
      • jed produces an output that is 100% compatible with Jed < 1.1.0
      • jed1.x produces an output that is 100% compatible with Jed >= 1.1.0
      • mf produces simple key:value output.
    • 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

fallback-to-msgid

If fallback-to-msgid is set, for those entries that would be omitted (fuzzy entries without the fuzzy flag) and for those that are empty, the msgid will be used as translation in the json file. If the entry is plural, msgid_plural will be used for msgstr[1]. This means that this option makes sense only for those languages that have nplurals=2.

Command Line Arguments

po2json in command-line parametrization support added to allow override default options.

• --pretty, -p: same as pretty = true in function options
• --fuzzy, -F: same as fuzzy = true in function options
• --format, -f: Output format (raw, jed, jed1.x, or mf)
• --domain, -d: same as domain in function options

Note: 'format': 'mf' means the json format used by messageFormatter in github.com/SlexAxton/messageformat.js This system does any pluralization within the string, so only msgstr[0] is used with these format, in a simple "key": "value" form.

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 );
});
