We can save other developers' time by documentation that this method always returns an empty string:

  /**
   * Returns a date string indicating how long ago (3 hours, 2 minutes)
   * something has happened or how long in the future something will happen
   * given a [reference] DateTime relative to the current time.
   */
  String formatDuration(DateTime reference) {
    return '';
  }

Or, better yet, implement the method :)

(please triage to Area=Pkg and CC alanknight)

... since Date was renamed to DateTime. DateFormat would be confusing once we get a Date class.

Reported by [email protected], Today (7 hours ago)
What steps will reproduce the problem?

1. Create a DateFormat: new DateFormat("yyyyMMdd");
2. format any arbitrary time with it: f.format(new DateTime.now())
3. try and reparse the same date

What is the expected output? What do you see instead?
An exception occurs, instead I'd have expected the dateformat to be able to parse a date that was formatted by it back again. I think this is caused by yyyy being formatted as a single 4 digit year but being parsed differently somehow.

DateFormat.parse() expects a string not a DateTime. A String generated from DateTime can be parsed without intl like DateTime.parse(new DateTime.now().toString()). If you want to use DateFormat.parse() you need to pass an appropriate format string.
Today (6 hours ago) Delete comment #353 [email protected]
I called DateFormat.parse using the same DateFormat generated in step 1, like this:

var format = new DateFormat("yyyyMMdd");
var timeStr = format.format(new DateTime.now());
var reparsed = format.parse(timeStr);

The third line of this will panic

The current implementation of NumberFormat will generate symbols of all supported languages into JS file. It is about 24KB. Though not very big, it will be better if it can be implemented like what DateFormat is -- using en_US as default, and loading other symbols with initDateFormatting and other methods. Thus, the application can implement lazy load and other mechanism to minimize the JS code size.

The intl package has Intl.plural which currently just forwards to Intl.select. It requires you to pass in "howMany" which presumably is either a plural category or number as described in:

http://unicode.org/reports/tr35/tr35-numbers.html#Language_Plural_Rules

But it does nothing to calculate the plural category for a given locale. It also doesn't have any templating facility to allow including the actual number within the text selected for the given plural category.

The intlx package (http://pub.dartlang.org/packages/intlx) has PluralFormat which takes a Map of cases, each of which can contain a pattern to replace with the actual number, and a locale to use to calculate plural categories, and then formats integers accordingly. The calculation of plural categories requires using a plural rules parser ahead of time to generate plural rules code for each locale which can be loaded into the application.

Demo: http://seaneagan.me/intlx/
Docs: http://seaneagan.me/intlx/docs/intlx/Plural.html

Proposal: move PluralFormat to the intl package and remove Intl.plural.

We currently don't have a mechanism for finding the locale from windows. The mechanism of asking systeminfo and parsing the result was incredibly slow and didn't work properly anyway. I believe we would need to add some sort of native API call to get the information reasonably.

We can ask if there are messages for a particular locale, but we can't get the list. It would be useful to do so, with the caveat that it's probably just the direct list, not taking into account substitutions, so if we have en, that would handle en_US, en_CA, etc., but we'd only have en in the list, as we don't have a way of going backwards to find all the possibilities.

In package:intl, Bidi acts as a namespace for static methods, which is generally an anti-pattern in dart, since dart libraries can act as namespaces for static methods, so a separate "bidi.dart" library maybe. However, most of these methods are duplicated for both TextDirections (RTL and LTR), so it seems like making them polymorphic to TextDirection would make sense. For a basic idea of what this would look like, see:

https://gist.github.com/seaneagan/5957736

Of course they wouldn't make sense for TextDirection.UNKNOWN, but I don't think TextDirection.UNKNOWN is necessary. I think it would make more sense just to reuse null for that concept.

Another option would be to keep them as static/top-level methods which receive a TextDirection, but that doesn't feel quite as nice.

Feature request for Intl NumberFormat:

Some number systems require more than one grouping size when formatting numbers. For example, see the Indian Numbering System, which groups by ten-thousands rather than by hundred-thousands: http://en.wikipedia.org/wiki/Indian_Numbering_System. This would render 1,00,000 rather than 100,000; which would require a number format of something like "#,##,##­0"

With deferred loading working better we should use it to load only part of the date-time information from the library instead of having the whole library or needing to load individual locales over XHR.

If the application wants to use deferred libraries for portions of itself, it would be best if the message catalog for that portion was loaded along with it. Right now the Intl.message calls are global, and we don't have a way to indicate a scope for the lookup, so that might require an API change. Alternatively, the implementation could remain as a single lookup but be a composite and have parts of it loaded when the application library is loaded.There are two issues there. One is identifying which messages need to be in which deferred chunks. That shouldn't be too bad, because we can base it off which file the message is implemented in and which chunk of the application that is. The second is having a runtime hook of some sort to load the messages when that deferred part of the application is loaded. That probably has to be done by convention, because we don't have that in the language.

This code

String languages(String locale) => Intl.select(locale, 
   {
     "fr" : "frensh",
     "en" : "english"
    },
    name: "languages", 
    args: [locale]);

is generated by intl:generate_from_arb with in locale FR likes that :

static languages(locale) => "{locale, select, fr {Français } en {Anglais }}";    

When I use the default locale (en) it work well with this angulardart code

    <select class="form-control"  ng-model="localeSelected">
        <option ng-repeat="language in ownerProfile['languages']" value="{{language}}">{{intl.languages(language)}}</option>
    </select>

But with the fr locale the value {locale, select, fr {Français } en {Anglais }} is instead of Français

When I edit the generated intl_fr.dart generated file and replace

  static languages(locale) => "{locale, select, fr {Français } en {Anglais }}";

by

static languages(locale) => {"fr":"Français","en":"Anglais"}[locale];

all works fine
I don't understand why the behaviour is different between the default locale code and a selected locale

'''I see ${Intl.plural(num_people,
          {'0': 'no one at all',

           'other': '$num_people other people'})} in $place.''''

What is the expected output? What do you see instead?

This would not work as Intl.plural expecte named args, ie
Intl.plural(num_people, one: "one", other: "other");

The problem with named arguments is that you have no way to pass
values for when num_people = 5, ie

Intl.plural(num_people, 5: "five", other: "other");

would not work as 5 is not an expected name for an argument

If in your application you import a package, which is translated

Duplicated library name 'messages_all'.
library messages_all;

when using the generate_from_arb functionality.
This applies also to the library in the translated files, e.g. messages_es

The cause is that in generate_localized.dart, the library name(s) are hardcoded.

generate_from_arb.dart allows to specify a file prefix, e.g.
--generated-file-prefix=base-

I suggest to use the file prefix also for the library names.

The intl package currently has Intl.gender to select messages based on gender. In addition when dealing with lists of people, languages have different rules to determine the gender. See:

CLDR:

http://unicode.org/reports/tr35/tr35-general.html#List_Gender

ICU:

http://icu-project.org/apiref/icu4j/com/ibm/icu/util/GenderInfo.html

Once issue #331 is fixed, it may be nice to have a method to complement it, which can select a message based on list gender. This could either be added to Intl.gender by making the "gender" argument also accept an Iterable, or a new method such as Intl.listGender.

Internationalization in Dart it's a mess, and it's a big stumbling-block.

Read the following article for an in depth explanation:

http://japhr.blogspot.it/2013/12/code-generation-and-polymer-i18n.html

We are at the verge of 2014. We need a modern internationalization system integrated right into Dart.

Those are the features we need:

• TRANSPARENCY : Once you write the code for a web page in a certain language, you must be able to localize it without going back and change anything of the original dart or html code. Switching between languages should be independent from the structure or the code of the page. For example a single call to a method at page load should localize automatically all strings and numerical values behind the scenes.
• INTEGRATED : Localization data should be integrated into the components (both for native or Polymer elements). Localization data should be portable like the elements and recognized at the language level. Missing or partial localizations should be marked as error. All international standards of metric units should be included and automatically parsed from strings, dates or numbers, with explicit conversion methods when the identification is not possible.
• AUTOMATED : The right localization, if present, should be automatically activated according to the browser language or location. The existence of localization data should be enough to make the localization happen. An explicitly statement must be provided to disable this feature. In this way just copying a new localization file for a specific language in the same folder of the web app sources should activate the localization, without changing any other file.

Thank you.

The intl package currently has unimplemented methods on DateFormat for this called formatDuration and formatDurationFrom. This is the wrong location for these APIs. Arbitrary DateFormat patterns don't match up to the corresponding CLDR data model.

The intlx package (http://pub.dartlang.org/packages/intlx) has DurationFormat which formats Durations, e.g. "5 minutes" or "5 min" and AgeFormat which formats DateTimes offset from now, e.g. "In 5 minutes" or "5 minutes ago" using CLDR data. See the following:

When a Dart app, which uses the intl package, is pub-built and compiled into JavaScript, dart2js creates 80 pattern and 80 symbol JSON files under the packages/intl directory. These 160 JSON files (2 per each existing locale whether used in the app or not) in turn must be loaded over to the server and downloaded by the clients. Is there a way to merge these files into one file? Is it not possible to keep the files for only the locales that the app requires. It seems to me that internationalization could be handled much more efficiently than it currently is.

While reorganizing ie testing we have enabled pkg tests.

pkg/intl/test/date_time_format_http_request_test fails, I will add a suppression.

If we're in most modern browsers (not Safari or IE10 yet) then there's an Intl namespace available with NumberFormat, DateFormat and Collation. We should look at exposing that functionality. We probably can't outright replace our own because we need something that will work outside the browser, has less less implementation variation, etc., but we should permit it, and exposing Collation would fill a big gap.

Internationalization in Dart it's a mess, and it's a big stumbling-block.

Read the following article for an in depth explanation:

http://japhr.blogspot.it/2013/12/code-generation-and-polymer-i18n.html

We are at the verge of 2014. We need a modern internationalization system integrated right into Dart.

Those are the features we need:

• TRANSPARENCY : Once you write the code for a web page in a certain language, you must be able to localize it without going back and change anything of the original dart or html code. Switching between languages should be independent from the structure or the code of the page. For example a single call to a method at page load should localize automatically all strings and numerical values behind the scenes.
• INTEGRATED : Localization data should be integrated into the components (both for native or Polymer elements). Localization data should be portable like the elements and recognized at the language level. Missing or partial localizations should be marked as error. All international standards of metric units should be included and automatically parsed from strings, dates or numbers, with explicit conversion methods when the identification is not possible.
• AUTOMATED : The right localization, if present, should be automatically activated according to the browser language or location. The existence of localization data should be enough to make the localization happen. An explicitly statement must be provided to disable this feature. In this way just copying a new localization file for a specific language in the same folder of the web app sources should activate the localization, without changing any other file.

Thank you.

User request to format numbers. See http://stackoverflow.com/questions/14865568/currency-format-in-dart

Seems like a good fit for intl, especially because intl has DateFormat.

Thanks!

Root cause is findSystemLocale() in pkg/intl/lib/intl_standalone.dart is looking for string prefixed with 'System Locale:' in stdout of systeminfo command, but on russian Windows the prefix is in russian:

What steps will reproduce the problem?
        test('> parseForIssueReport', () {
            final DateFormat rfc822Formatter = new DateFormat("EEE, dd MMM yyyy HH:mm:ss Z","en_US");
            final DateTime dt = rfc822Formatter.parse("Wed, 02 Oct 2002 15:00:00 +0230");

            expect(dt.timeZoneOffset.inMinutes, 150);
        }); // end of 'parseForIssueReport' test

What is the expected output? What do you see instead?
+230 should be 150 minutes!

What version of the product are you using? On what operating system?
Dart SDK 1.1.3 + intl 0.9.4

It would be nice if you could indicate what locale the default message texts were in and have an initialize not give you an error in that case. Otherwise you need to special-case it in your initialization routine.

to reproduce:
var d = DateTime.parse('0001-02-03'); // iso 8601 requires 0-padding.
DateTime.parse('1-2-3'); // FormatException. we expect this.
var f = new DateFormat('yyyy-MM-dd');
     // the docs here (ctrl+f search for "number")
     // https://api.dartlang.org/docs/channels/stable/latest/intl/DateFormat.html
     // say that yyyy is supposed to 0-pad.
f.format(d); // yields '1-02-03'.
     // that's not right, year was supposed to be 0-padded.

// let's try the example from the docs:
var f2 = new DateFormat('yyyyy.MMMMM.dd GGG hh:mm aaa');
var d2 = DateTime.parse('1996-07-10 12:08');
f2.format(d2);
// yields '1996.J.10 AD 12:08 PM', but the docs say it yields '01996.July.10 AD 12:08 PM'
// notice how the promised output has 0-padding, but the actual doesn't.
// also the promised output spells out 'July', but the actual doesn't.

the lack of 0-padding is annoying because DateTime.parse demands 0-padding,
but DateFormat won't produce it, so i get exceptions when i
send the output of one to the other.
