GetText support for CommonJS and the browser

Lightweight GetText for Javascript

This module provides GetText support for both CommonJS and the browser.

Categories and locales are not supported, and will never be. It is assumed that the content currently loaded into GetText matches the current locale.

Server-side example

var fs = require('fs');
var GetText = require('gettextlight').GetText;

function errorHandler(err) {
    console.log('[GetText][' + err.domain_name + '][#' + err.line + '] ' + err.message);
}

GetText.load(fs.readFileSync('en/messages.po', 'utf-8'), errorHandler);
GetText.loadDomain('domain1', fs.readFileSync('en/domain1.po', 'utf-8'), errorHandler);

console.log(GetText.ngettext('person', 'persons', 12));
console.log(GetText.dpgettext('domain1', 'animal', 'cat'));

Browser example

<script src="gettextlight/lib/index.js"></script>
<script>//<![CDATA[
function errorHandler(err) {
    console.log('[GetText][' + err.domain_name + '][#' + err.line + '] ' + err.message);
}

function on_localization_data(data) {
    var numPOFiles = data && data.length >>> 0;
    while (numPOFiles > 0) {
        var po = data[--numPOFiles];
        // if po.domainName is undefined or null, the default domain ('messages') is used
        window.GetText.loadDomain(po.domainName, po.content, errorHandler);
    }

    console.log(window.GetText.ngettext('person', 'persons', 12));
    console.log(window.GetText.dpgettext('domain1', 'animal', 'cat'));
}

//]]>
</script>
<!-- query some JSONP content -->
