l10n 2.0.4

Creates translatable PO-Files, strong orientation to xgettext

l10n

Easy to use generator for .arb-Files
Helps if you want to translate your application

l10n >= v2.x

This is a complete rewrite. l10n now fully supports Intl.message and .ARB-Files

Usage

• First install l10n with pub global activate l10n

Now mkl10n should be available on the command-line.

Go to the package you want to translate.

    mkl10n -l de .

Yes - that's it!

Your .arb-Files are in l10n. You should see intl_messages.arb and intl_de.arb

Translate intl_de.arb

    # Run this command again
    mkl10n -l de .

Your generated dart-Files are in lib/_l10. You should see messages_all.dart and messages_de.dart

Import messages_all.dart in your app.

// Include this if you run your app in the browser
import 'package:intl/intl_browser.dart';

// Include this if you run your app on the cmdline
import 'package:intl/intl_standalone.dart';

import 'package:l10n/l10n.dart';
import 'package:<your package>/_l10n/messages_all.dart';

Future main() async {
    // Determine your locale
    final String locale = await findSystemLocale();
    final String shortLocale = Intl.shortLocale(locale);

    // Avoids error message:
    //      LocaleDataException: Locale data has not been initialized,
    //      call initializeDateFormatting(<locale>).
    await initializeDateFormatting(locale);

    // Initialize translation-table
    await initializeMessages(shortLocale);

    // Here comes you app-code
    // ...
}

On GitHub you can find a cmdline-example and a browser-example.

Browser-Example Live-Version This is the most simple version of a translated HTML-page I could think of...

More details

As mentioned above Intl.message is fully supported. More infos can be found on pub

Hey but there is more!

In my opinion Intl.message is to complex for most situations so I also support my own l10n syntax.

    // Yup - this prints 'Second test'
    // And after you have translated the intl_de.arb to German it prints 'Zweiter Test' 
    print(l10n("Second test"));

Check out the source on GitHub

But hey - we also have HTML-Files...

Sure!

<main class="cols">
   <div>
       <div class="translate">_("Hi Mike")</div>
       <div class="translate">_("My cat's name is 'Pebbles'")</div>
   </div>
</main>

That's how it works in HTML. Wrap the string you want to translate with _(...) You can also wrap it with l10n(...) but I prefer _(...)

It get's even better - if you have a dart-File with HTML-Included like so
it's also fully scanned by mkl10n

Flutter

This should seamlessly work with Flutter. Should because I haven't tested it with Flutter
If it fails please write file an issue report.
