jsxgettext

A node module with a CLI that extracts gettext strings from JavaScript, EJS, Jade, Jinja, Swig and Handlebars files. Uses a real parser, acorn, for JavaScript files and recognizes the following uses:

gettext("Hello world!");
gettext("Hello" + ' world!');
myModule.gettext("Hello " + 'world!');
gettext.call(myObj, "Hello " + 'world!');

It also extracts comments that begin with "L10n:" when they appear above or next to a gettext call:

// L10n: Don't forget the exclamation mark
gettext("Hello world!");  // L10n: Salutation to the world

   --support-module           Support module to require for specific language parsers

support-module

In order to be able to parse the templates, some language parsers need a custom module to be imported which add tags to the parser instance.

Swig

For swig the support-module parameter is required. The module should have a function in module.exports which allows the swig instance to be supplied.

Example:

// support module
var trans = require('./trans')
  , blocktrans = require('./blocktrans');

module.exports = function(swig) {
  swig.setTag("trans", trans.parse, trans.compile, trans.ends, trans.blockLevel);
  swig.setTag("blocktrans", blocktrans.parse, blocktrans.compile
              , blocktrans.ends, blocktrans.blockLevel);
};
