xgettext-dust

tl;dr - don't reinvent the wheel. If you're using Dust and need to internationalize your app, you should be using gettext.

Parses dust templates and extracts strings, generating a Gettext POT file for use in i18n translation systems.

We take a dust template that has one or more @i18n helper calls:

{@i18n singular="Hello, {first_name}, you have one message." plural="Hello, {first_name}, you have {message_count} messages!"/}

And then output the corresponding POT file, for use in Gettext translation workflows:

#: examples/basic2.dust:10
msgid "Hello, {first_name}, you have one message."
msgid_plural "Hello, {first_name}, you have {message_count} messages!"
msgstr[0] ""
msgstr[1] ""

Support is included for singular, plural, context and file/line reference. Instead of sprintf style replacements, we leverage the Dust placeholders, which functionally work the same way. Parsing is done via the real dust parser (using the generated AST from the dust templates), so all valid Dust syntax and templates are supported.

Installing

npm install xgettext-dust

Usage Example

var xgettextDust = require('xgettext-dust');
 
var generatedPOT = xgettextDust.parseFiles('templates/*.dust', {
    version: '0.0.1',
    langTeam: 'team',
    bugReports: '[e-mail]',
    root: process.cwd()
});
 
// do something with the output, save to file, etc.
fs.writeFileSync('dustStrings.pot', generatedPOT, 'utf8'); 
 

The first parameter is a glob pattern, so you can scan directories recursively looking for templates. The glob search starts looking in the root parameter -- the above example just uses process.cwd().

Running Tests

Make sure you have Mocha installed:

nom install -g mocha
npm test
