Convert PO files to Javascript objects or JSON strings. The result is Jed-compatible.
Install the module with: npm install po2json
var po2json = require('po2json');
po2json translation.po translation.json
If you are using Jed >= 1.1.0, be sure to specify that format specifically.
po2json translation.po translation.json -f jed1.x
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:fuzzyWhether to include fuzzy translation in JSON or not. Should be eithertrueorfalse. Defaults tofalse.stringifyIftrue, returns a JSON string. Otherwise returns a plain Javascript object. Defaults tofalse.prettyIftrue, the resulting JSON string will be pretty-printed. Has no effect whenstringifyisfalse. Defaults tofalseformatDefaults toraw.rawproduces a "raw" JSON outputjedproduces an output that is 100% compatible with Jed >= 1.1.0jedoldproduces an output that is 100% compatible with Jed < 1.1.0mfproduces simple key:value output.
domain- the domain the messages will be wrapped inside. Only has effect ifformat: 'jed'.fallback-to-msgidIftrue, 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.
Parse a PO file to JSON
po2json.parseFile(fileName[,options], cb)fileName- path to the po fileoptions- same as forpo2json.parsecb- a function that receives 2 arguments:errandjsonData
Parse a PO file to JSON (synchronous)
po2json.parseFileSync(fileName[, options])fileName- path to the po fileoptions- same as forpo2json.parse
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, jedold, or mf)
- --full-mf, -M: return full messageformat output (instead of only translations)
- --domain, -d: same as domain in function options
- --fallback-to-msgid': 'use msgid if translation is missing (nplurals must match)
Note: 'format': 'mf' means the json format used by messageFormatter in github.com/SlexAxton/messageformat.js
and jedold refers to Jed formats below 1.1.0
var po2json = require('po2json'),
fs = require('fs');
fs.readFile('messages.po', function (err, buffer) {
var jsonData = po2json.parse(buffer);
// do something interesting ...
});
var po2json = require('po2json');
po2json.parseFile('messages.po', function (err, jsonData) {
// do something interesting ...
});
var po2json = require('po2json');
var jsonData = '';
try {
jsonData = po2json.parseFileSync('messages.po');
// do something interesting ...
} catch (e) {}
var po2json = require('po2json'),
MessageFormat = require('messageformat');
po2json.parseFile('es.po', { format: 'mf' }, function (err, translations) {
var pFunc = function (n) {
return (n==1 ? 'p0' : n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 'p1' : 'p2');
};
pFunc.cardinal = [ 'p0', 'p1', 'p2' ];
var mf = new MessageFormat(
{
'es': pFunc
}
);
var i18n = mf.compile( translations );
});
var po2json = require('po2json'),
MessageFormat = require('messageformat');
po2json.parseFile('messages.po', { format: 'mf', fullMF: true }, function (err, jsonData) {
var mf = new MessageFormat(
{ [jsonData.headers.language]: jsonData.pluralFunction }
);
var i18n = mf.compile( jsonData.translations );
});
var po2json = require('po2json'),
Jed = require('jed');
po2json.parseFile('messages.po', { format: 'jed' }, function (err, jsonData) {
var i18n = new Jed( jsonData );
});
If you are using an older version of Jed, be sure to specify this format specifically.
var po2json = require('po2json'),
Jed = require('jed');
po2json.parseFile('messages.po', { format: 'jedold' }, function (err, jsonData) {
var i18n = new Jed( jsonData );
});
