Make sure that external script dependencies have local fallbacks

Xforms validation rules are ignored and forms are submitted regardless of whether it passes or not. Removing the plugin fixes this problem.

Control default PreferredLanguage while scanning the target types and registering localizarion values

Right now i manually add it foreach category:
var key = $"/categories/category[@name="{cat.Name}"]/description";

var synchronizer = new ResourceSynchronizer();
synchronizer.RegisterManually(new[] { new ManualResource(key, cat.Name) });

if
DbLocalizationProvider.LocalizationProvider.Current.GetString(key) returns empty.

Currently it is not possible to add following translation: "This is <a href="">some link</a> in text "

Localized resources might contain simple HTML markup. One might argue that HTML should not be in resources at all, and message should be formed from separate pieces.
In most cases it would add huge overhead and would not make sense for resource editors as they would loose context of each translation piece and how they fit together.

Example:

[LocalizedResource]
public static class MyResources
{
    public static string StatusMessage => "Inserted <b>{0}</b> records, updated <b>{1}</b> records.";
}

For such cases rich editor might be helpful as for regular resources (without HTML tags) it would render as usual.

This will make it really easy to translate EPiServer UI, and other gadgets and modules that have embedded resources.

For both resources and models

The current version of LocalizationProvider doesn't allow Episerver.Cms.Core or Episerver.Cms.UI.Core above 10.0.0. This blocks a lot of other packages from updating. It would be very helpful if you released a version with support for the latest versions of those packages.
Thank you!

[ContentType(...)]
[LocalizedModel(Prefix = "/contenttypes/startpage/")]
public class StartPage : PageData
{
    [PropertyCaption("This is page header")]
    [PropertyHelp("Please fill in this property for title of the page")]
    public virtual string PageHeader { get; set; }
}

This should generate:

• /contenttypes/startpage/properties/pageheader/caption = "This is page header"
• /contenttypes/startpage/properties/pageheader/help = "Please fill in this property for title of the page"

Restrict some editors to have access only to predefined resources or resources that match pattern (like contains, starts with, etc).

Could be used in fallback mechanism for built-in localization provider.
Case: during startup preferred culture is set to "no" -> default values for resources are stored in "no" culture. When opening admin interface and set UI culture no "en" -> nothing is translated, user will see resource keys instead of values.

Invariant default culture could be used to store default resource translations coming from code, to provide resource value for the cases when translation is not found in requested culture.

public class HelpTextAttribute : Attribute {}

namspace MyNamespace
{
    ...

[LocalizedModel]
public class MyModel
{
    [DisplayName(...)]
    [HelpText]
    public string Username { get; set; }
}

Should render MyNamespace.MyModel.Username-HelpText

Sometimes you may get this exception on startup

Since this is a localization tool, it would be logical to add translations to the UI components. i.e. UI menus.

Add possibility to preview what changes will be applied prior to actually import the resources

Very problematic if one needs to delete a lot of obsolete resources

This is very common requirement to localize enum values.

Something like @Html.Translate(myEnum) would be great.

When I connect empty database to project with installed DbLocalizationProvider, sometimes I get

[SqlException (0x80131904): Invalid object name 'dbo.LocalizationResources'.]
   System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action'1 wrapCloseInAction) +282

It looks like ResetSyncStatus called before EF creates tables in database.

If Username is required @Html.LabelFor(m => m.Username) should render "Username *"

Localization becomes messy when there are multiple format arguments passed in. Also, editor has no clue about what type of information will be inserted in indexed placeholder.

[LocalizedResource]
public static class WelcomeResources
{
    public static string HelloMessage => "{0} {1}! You look great today!";
}

@Html.Translate(() => WelcomeResources.HelloMessage, userViewModel.FirstName, userViewModel.LastName);

Would be great if I could use it as follows

[LocalizedResource]
public static class WelcomeResources
{
    public static string HelloMessage => "{FirstName} {LastName}! You look great today!";
}


@Html.Translate(() => WelcomeResources.HelloMessage, new { FirstName = userViewModel.FirstName, LastName = userViewModel.LastName});

or even

@Html.Translate(() => WelcomeResources.HelloMessage, userViewModel);

Look at EPiServer.Cms.Shell.UI.ContentDataMetadataProvider

This will not generate localization key:

[LocalizedModel]
public class MyModel
{
    public int? MyProperty { get; set; }
}

Not able to edit second language's field in admin UI if there is no value already there. Might be bug in latest version?

Or populate new language from default values from the code

"Show Empty Resources" filter shows also records with key containing string "Empty"

If string property in viewmodel is assigned with "=" instead of getter "=>", property is not registered.

This will not register as resource:

[LocalizedResource]
public class SampleResources
{
    public string MyResource = "this is test";
}

Throw an exception if there are duplicate resource keys

Error:

Either ErrorMessageString or ErrorMessageResourceName must be set, but not both.

Hello Valdis,

This is great stuff, I have previously used the Localization Provider from Jeroen and it really improved the Editor Experience.
Now that you have created a new alternative, I wanted to give you my two cents of one of the scenarios that sometimes adds complexity:

• Handling of Load Balanced scenarios, to invalidate cache in web-fronts upon update of translations.

Jeroen solved the issue by adding event handlers to the remote events on EPiServer (since the translations are pages)

In your implementation, it seems like you are using CacheManager, correct?
If so, I can see two options to enable NLB scenarios:

• Use Redis as a centralized out-of-process cache (http://social.technet.microsoft.com/wiki/contents/articles/26711.asp-net-webapi-use-redis-as-cachemanager.aspx)
• Increase complexity to manage cache expiration.

Please let me know if my comments makes sense, and happy to help/further converse :)

Keep up the library creation! It is quite refreshing.

Regards,
. Wacdany

Steps to reproduce:

1. Add new resource with default translations;
2. Start web site;
3. Change default value in code;
4. Start web site;
5. Default values stays the same as defined in step 1;

Expected:

Default values should be taken from code, unless editor defines non-default value.
