Disney language:
- .net language must be installed on machine which builds the solution - if not - it doesn't generate the satellite localization dlls.
Even though the resx files are included into the main dll, the app (web) doesn't access them.
- Create dll which just does the language registration so we can use a powershell script to execute on build (build action).
Check in the custom culture generator dll to 'lib'
Visual Studio - restart to let VS update the .NET language list (especially removing a language)


Sisulizer Tool

We have one license of the software (currently installed on Stefan-PC). It creates translations (resx files) for Visual Studio solutions. Every custom language (i.e. en-US-Disney) needs it's extra set of resource files, generated by Sisulizer.

Install Sisulizer Tool

Either download the tool from https://www.sisulizer.com (Professional Developer version) or get it from network share \\mlsnas\Public\Software\Sisulizer Tool

License key can be found in https://docs.google.com/spreadsheets/d/1eOP-rSso_CzctFzv29Hp-Lw5EIalz72Ym6EE3lEzQzA/edit#gid=711274036

Add New Custom Language to Core

  • Open Sisulizer project file /src/MarineLMS - Sisulizer Translation.slp
  • Add a new language variant (Tools → General... → Languages)
    • Select a specific language you want to create a variant for and click 'Add variant...'.
      • Important: you must select a country specific language like EN-US. You can't select just EN.
    • Tab Codes: add name for the ISO variant (i.e. Disney). Don't change the Windows code (which is autom. updated if the ISO variant name is added)
    • Tab Names: add the same variant names in both text fields as ISO variant (i.e. Disney)
    • The resulting custom language will be like EN-US-Disney
  • Add new custom language to the slp project
    • Open drop down list for languages in tool bar and select Add...
    • Select language and add to 'Selected Languages'
      • If you add a country specific language (i.e. FR-CA) and the general language (i.e. FR) is not added a warning is issued. Select No
      •  
    • Select OK to complete adding a new language
  • Export resx files into checked out solution/project
  • Manually add all resx files to the VS solution/project
  • Set the Custom Tool = PublicResXFileCodeGenerator and Custom Tool Namespace for each resx file to match the original neutral resx files.
  • Check in the new resx files to Git
  • Check in/update the Sisulizer configuration file ('MarineLMS - Sisulizer Translation.slp') to Git

Update Resx Files and/or Make Translations

  1. Open Sisulizer project file /src/MarineLMS - Sisulizer Translation.slp
  2. Project → Scan for Changes 
  3. Select All to view all text which can be translated.
  5. Ctrl + F5 to search for any term you need to translate
  6. Make any translation/changes you need
  7. Project → Build in Selected Language will generate the updated/new resx files
  8. Save the Sisulizer project
  9. Open MarineLMS solution in Visual Studio
    1. Include newly created custom language specific resx files (created by Sisulizer) to MarineLMS solution
      1. The easiest way to find any new resx files created by Sisulizer is to check Sourcetree for uncommitted changes/unstaged files
      2. In VS, right click resx file and select Include in Project (enable Show All Files in the Solution Explorer)
    3. Update the newly added resx file's properties (2) to match the values of the counterpart's resx file (= default language resx file)
      1. Custom Tool: PublicResXFileCodeGenerator
      2. Custom Tool Namespace: [[namespace from corresponding default resx file]]
    4. Example: if you added AssessmentSummaryRx.en-US-Disney.resx, there is always a resx file AssessmentSummaryRx.resx.
  11. Commit all resx files and the Sisulizer project file /src/MarineLMS - Sisulizer Translation.slp and /src/MarineLMS - Sisulizer Translation.sds

Support Language Specific Date/Time Formats

In order to support different date and time formats for different locales all UI elements need to use the ILMSFormatter interface (class Formatters). The Formatters' Resx file contains date and time formats. Sisulizer context: MarineLMS.Web.Main\MarineLMS.Web.Main.csproj.Strings.MarineLMS.Web.Main.Util.FormattersRx.

Support Language Specific DatePicker

The Bootstrap date picker needs a separate js file for translations for different locales. For example bootstrap-datepicker.fr.min.js for French. The date picker doesn't support country specific language translations. That is, country specific languages like fr-CA and fr-FR would refer to fr only.

The following steps need to be done to add a new language to Visual Studio project Web.Main:

Use DatePicker in cshtml

The date picker classes data-date-format and data-date-language must exist and have the correct values.

div class="input-append date pull-left input-datepicker" data-date-format="@Model.DateFormatter.ShortDateAllNumbersFormat" data-date-language="@Model.DateFormatter.CurrentTwoLetterISOLanguageName" title="start date">

data-date-format: The date format for the DatePicker must contain numbers only - no month name like Jan or January is allowed.

data-date-language: The date language must be the 2 letter language name like en, fr,... The language name like 'fr' is deferred from the js script like 'bootstrap-datepicker.fr.min.js'.

Notes

Only Core web projects currently contain resx files and therefore only Core web projects are imported into Sisulizer.
