Error: Lexical error on line 1. Unrecognized text.

Working on Mac when creating folders it also creates a bunch of extra invisible files such as .DS_Store, these files then gets included by the xgettext package and obviously throws an error because they are invalid handlebars files.

Could the -D parameter references and parse only .hbs or .handlebars files?

Had to clear extra files using the commands described inside mikeal/tako#4 but then as soon as something is modified, the file gets created again

// Of course create an extention-language mapping array for the other supported languages: Swig, Volt and EJS
if (options.directory) {
  readdirp({root: options.directory, fileFilter: ['*.hbs', '*.handlebars']}, function(err, res) {
    if (err) {
      throw err;
    }

    parseFiles(res.files.map(function (file) {
      return file.fullPath;
    }), output);
  });
} else {

Could you post the whole command (including parameters) which you use to run xgettext-template?
I haven't used it much outside of Poedit.

//package.json
"scripts": {
    "po": "xgettext-template -L Handlebars -D views -o en.po --from-code utf8 --force-po"
},

2 thoughts on this:

• xgettext-template should match xgettext as close as possible (although still lacking many parameters). There doesn't seem to be an input-file filtering option in xgettext as far as I can tell. The way you filter is by piping a selection of files. Can you give this a try?
• The -D parameter has the wrong effect. It should only change the root directory, not provide all files in that directory as input. I'll track this in a separate issue.

I had some issues with the command from the SO above, but this worked for me:

find views -name "*.handlebars" \
| xargs xgettext-template -L Handlebars --from-code utf8 --force-po -o en.po

(I guess you should remove the slash and write it as one line in package.json)

Indeed the above command worked just fine! Thanks!

"scripts": {
    "po": "find views -name '*.handlebars' | xargs xgettext-template -L Handlebars --from-code utf8 --force-po -o en.po"
},

You're welcome!
Last step would be to test this cross-platform (Windows) and probably replace find/xargs with JS alternatives. Feel free to add the result should you go that way.

I've ended up using a Grunt task to handle the .pot / .po / .json transformations. Here is the sample of code:

// node_modules required:
// xargs - for compatibility
// po2json - generate json file from a .po to be used by Jed
// grunt-shell - execute shell commands

// tasks/po.js
var locales = ["en_US", "es_US", "fr_CA"];

module.exports = {
    shell: {
        options: {
            failOnError: true,
            preferLocal: true
        },
        xgettext: {
            command: "find js/receipt/templates -name '*.hbs' | xargs xgettext-template -L Handlebars -o js/receipt/po/ref.pot --from-code utf8 -j --force-po"
        },
        msgmerge: {
            command: locales.map(function (locale) {
                return "msgmerge js/receipt/po/" + locale + ".po js/receipt/po/ref.pot -U\n";
            }).join("")
        },
        po2json: {
            command: locales.map(function (locale) {
                 return "po2json js/receipt/po/" + locale + ".po js/receipt/json/" + locale + ".json -f jed1.x -p true\n";
            }).join("")
        }
    }
}

//Gruntfile.js
grunt.registerTask(
    'po', [
        'shell:xgettext',
        'shell:msgmerge',
        'shell:po2json'
    ]
);
