i18next-conv

Introduction

Project goal is to convert files from gettext to i18next json format and vice versa.

Installation

1. first install node.js from nodejs.org.
2. npm install i18next-conv -g

Usage

convert .mo or .po to i18next json

in your console type:

for help:

i18next-conv -h

to convert a .mo or .po file to i8next json:

i18next-conv -l [domain] -s [sourcePath] -t [targetPath]

eg.: i18next-conv -l en -s ./locales/en.po -t ./locales/en/translation.json

if no target (-t) is specified file will be stored to [sourceDir]/[domain]/translation.json.

to convert i18next json to a .mo or .po file:

i18next-conv -l [domain] -s [sourcePath] -t [targetPath]

eg.: i18next-conv -l en -s ./locales/en.translation.json -t ./locales/en/translation.mo (or .po)

if no target (-t) is specified file will be stored to [sourceDir]/[domain]/translation.po.

for utf8-encoded po-files add these lines to your po file:

"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"

It is necessary if you get corrupted output from the command above.

to filter incoming po-file translations, pass the path to a module that exports a filter function:

i18next-conv -l [domain] -s [sourcePath] -t [targetPath] -f [filterPath]

eg.: i18next-conv -l en -s ./locales/en.po -t ./locales/en/translation.json -f ./filter.js

The filter module should export a single function that accepts the gettext object, the domain and a callback as its arguments. The function can then add/edit/delete translations, invoking the callback with an error object and the translation table.

eg.

module.exports = function(gt, domain, callback) {
 	var err;
 
 	// Delete all keys without comments
 	gt.listKeys(domain).forEach(function(key) {
 		var comment = gt.getComment(domain, "", key);
 		if (!comment) {
 			gt.deleteTranslation(domain, "", key);
 		}
 	});
 
 	callback(err, gt._domains[gt._textdomain]._translationTable);
};
