PoExtractor

This utility extracts translatable strings from the C# and VB code, Razor templates and Liquid templates to POT (portable object template) files. It is designed to follow conventions used in the OrchardCore project.

PoExtractor is distributed as a dotnet global tool and it is available on the official NuGet.org feed in two versions:

• PoExtractor - a general purpose utility for extracting translatable strings from C#, VB code and Razor views
• PoExtractor.OrchardCore - the same utility with the additional support for extracting translatable strings from Liquid templates.
  • In order to be able to parse Liquid templates, it needs to reference OrchardCore.DisplayManagement.Liquid package, where the Liquid filters are defined

Installation

Install with the following command:

dotnet tool install --global PoExtractor

or

dotnet tool install --global PoExtractor.OrchardCore

The latest version of PoExtractor.OrchardCore is build against OrchardCore 1.0.0-beta3-71077. If you want to use PoExtractor with OrchardCore 1.0.0-RC1 please use version 0.2.0-rc1

dotnet tool install --global PoExtractor.OrchardCore --version 0.2.0-rc1

If you cant to use PoExtractor with the preview version of OrchardCore, please use version 0.4.0-rc1-13272

dotnet tool install --global PoExtractor.OrchardCore --version 0.4.0-rc1-13272

Usage

extractpo inputpath outputpath

or

extractpo-oc inputpath outputpath

Extracts all translatable strings from projects at the specified input path and saves generated POT files at the specified output path. It creates one POT file per a project. This includes liquid views.

Uninstallation

dotnet tool uninstall --global PoExtractor

or

dotnet tool uninstall --global PoExtractor.OrchardCore

Limitations

PoExtractor assumes, the code follows several conventions:

• IStringLocalizer or a derived class is accessed via a field named S (This is a convention used in Orchard Core)
• IHtmlLocalizer or a derived class is accessed via a field named H (This is a convention used in Orchard Core)
• IStringLocalizer or IHtmlLocalizer is accessed via a field named T (This is a older convention used in Orchard Core)
• Liquid templates use the filter named t (This is a convention used in Fluid)
• context of the localizable string is the full name (with namespace) of the containing class for C# or VB code
• context of the localizable string is the dot-delimited relative path the to view for Razor templates
• context of the localizable string is the dot-delimited relative path the to template for Liquid templates

Example

C# code:

namespace OrchardCore.ContentFields.Fields { 
    public class LinkFieldDisplayDriver : ContentFieldDisplayDriver<LinkField> {
        private IStringLocalizer S;

        public LinkFieldDisplayDriver(IStringLocalizer<LinkFieldDisplayDriver> localizer) {
            S = localizer;
        }

        public override async Task<IDisplayResult> UpdateAsync(LinkField field, IUpdateModel updater, UpdateFieldEditorContext context) {
            bool modelUpdated = await updater.TryUpdateModelAsync(field, Prefix, f => f.Url, f => f.Text);

            if (modelUpdated)
            {
                var settings = context.PartFieldDefinition.Settings.ToObject<LinkFieldSettings>();

                if (settings.Required && String.IsNullOrWhiteSpace(field.Url))
                {
                    updater.ModelState.AddModelError(Prefix, S["The url is required for {0}.", context.PartFieldDefinition.DisplayName()]);
                }
            }

            return Edit(field, context);
        }
    }
}

VB code:

Namespace OrchardCore.Modules.GreetingModule 
    Public Class Greeting
        private readonly S As IStringLocalizer(Of Greeting)

        Public Sub New(ByVal localizer As IStringLocalizer(Of Greeting))
            S = localizer
        End Sub

        Public Sub Saulation(byVal name As String)
            Console.WriteLine(S("Hi {0} ...", name))
        End Sub
    End Class
End Namespace

Razor view:

@model OrchardCore.ContentFields.ViewModels.EditLinkFieldViewModel

<div class="row">
    <fieldset class="form-group col-md-12">
        <label asp-for="Url">@Model.PartFieldDefinition.DisplayName()</label>
    </fieldset>
    <fieldset class="form-group col-md-6" asp-validation-class-for="Url">
        <input asp-for="Url" class="form-control content-preview-text" placeholder="@settings.UrlPlaceholder" required="@isRequired" />
    </fieldset>
    <fieldset class="form-group col-md-6" asp-validation-class-for="Text">
        <label asp-for="Text" @if (settings.LinkTextMode == LinkTextMode.Required) { <text> class="required" </text>  }>@T["Link text"]</label>
        <input asp-for="Text" type="text" class="form-control content-preview-text" placeholder="@settings.TextPlaceholder" required="@isTextRequired" />
    </fieldset>
</div>

Liquid template:

div class="page-heading">
   <h1>{{ "Page Not Found" | t }}</h1>
/div>
