Extracts gettext strings from JavaScript, EJS, Jade, Jinja and Handlebars files.

jsxgettext Build Status NPM version

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!');, "Hello " + 'world!');
ngettext("Here's an apple for you", "Here are %s apples for you", 3);
ngettext("Here's an apple" + ' for you', "Here are %s apples" + ' for you', 3);
myModule.ngettext("Here's an apple" + ' for you', "Here are %s apples" + ' for you', 3);, "Here's an apple" + ' for you', "Here are %s apples" + ' for you', 3);

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   

"L10n:" is a default value and you can change it with -c option.
