WebSharper.UI 4.2.6.119

This is a bugfix release for WebSharper.UI 4.2. See the associated WebSharper release.

Fixes

• dotnet-websharper/core#948 Translation fix applied for erased unions used internally in UI for performance.

WebSharper.UI 4.2.6

This is a feature release for WebSharper.UI 4.2. See the associated WebSharper release.

Improvements

• #171 Templating: Support writing <ws-*> template instantiations from the server side with .Doc(keepUnfilled = true), so that these instantiations can be applied on the client side.

Fixes

• #170 Templating: Fix issue that prevented applying <ws-*> instantiation for a template declared later in the file in ClientLoad.FromDocument mode.
• #176 Routing: Recognize relative href path when parsing clicked links to apply client-side routing.
• #177 Fix code output when using .V on a Var<Doc>.

WebSharper UI 4.2.5

This is a feature release for WebSharper.UI 4.2. See the associated WebSharper release.

Enhancements

• Add Router.InstallInto and Router.InstallHashInto, which are similar to Router.Install and Router.InstallHash respectively, except that they take a Var<'EndPoint> as argument rather than creating and returning one.

Fixes

• #164 Remove click event handler on Doc.Checkbox, only keeping change, to avoid setting the Var twice.
• #166 Add proxy for quotation-based .OnXyz(...) event handlers.
• #167 Fix initial value of Var.Make whenever an initial value is available from the View.
• #168 Add View.TryGet : View<'T> -> option<'T> which returns the current value of a View if available, or None if not (eg if a View.MapAsync hasn't returned yet).

WebSharper.UI 4.2.4

This is a minor feature release of WebSharper.UI, out-of-band from WebSharper.

Features

• #163 Allow using the on.afterRender attribute, the Elt.OnAfterRender() method and the ws-onafterrender template hole from the server side just like other event handlers.

• #165 Add variadic overload for Attr and Doc-typed hole instantiation. For example, the following:

  MyTemplate()
      .Body(
          [
              h1 [] [text "Hello!"]
              p [] [text "Welcome to my page."]
          ]
      )

  can now be written as:

  MyTemplate()
      .Body(
          h1 [] [text "Hello!"],
          p [] [text "Welcome to my page."]
      )

Fixes

• #138 Fix an exception thrown when editing a template file while the application is running and serverLoad is set to ServerLoad.WhenChanged.

WebSharper.UI 4.2.3

This is a feature release for WebSharper.UI 4.2. See the associated WebSharper release.

Enhancements

Templating type provider

• #161 Add .Bind() : unit template terminating method to directly bind holes to the current document. This is available on the client-side only if the template is declared with ClientLoad.FromDocument.
• #161 Add optional argument .Doc(keepUnfilled: bool) for the server side to leave unfilled holes in the document, so that they can be used on the client side by .Bind().

WebSharper.CSharp

• #160 Add extension methods to bring C# in line with F#:

  // Extensions on ListModel<K, T>:
  View<IEnumerable<V>> Map(Func<T, V> f);
  View<IEnumerable<V>> Map(Func<K, View<T>, V> f);
  View<IEnumerable<V>> MapLens(Func<K, Var<T>, V> f);
  Doc Doc(Func<T, Doc> f);
  Doc Doc(Func<K, View<T>, Doc> f);
  Doc DocLens(Func<K, Var<T>, Doc> f);
  ListModel<K, V> Wrap(Func<V, T> extract, Func<T, V> wrap, Func<V, T, V> update);
  
  // Extension on Var<FSharpList<T>>:
  Doc DocLens(Func<T, K> key, Func<K, Var<T>, Doc> f);

WebSharper.UI 4.2.2

This is a bugfix release for WebSharper.UI 4.2. See the associated WebSharper release

Enhancements

• Updated to use HtmlAgilityPack version 1.7.1

Fixes

• dotnet-websharper/core#919 C# analyzers for WebSharper errors and UI template code generation works as expected.
• dotnet-websharper/core#920 WebSharper binaries targeting .NET 4.6.1 are no longer depending on anything targeting .NET Standard.

WebSharper.UI 4.2.1

This is the first stable release of WebSharper.UI 4.2. See the associated WebSharper release

Improvements

• #157 Add Attr.ClassPred and Attr.DynamicClassPred for adding CSS classes conditionally. ClassPred also supports the .V syntax: Attr.ClassPred "hidden" (currentPage.V = "home").
• #153 Add View.WithInit and WithInitOption.
  View.WithInit init view is equivalent to view, except that if view is in a waiting state, its initial value is init instead.
  Similarly, View.WithInitOption view is equivalent to View.Map Some view, except that if view is in a waiting state, its initial value is None instead.

Fixes

• #152 If a template only specifies one of styles and meta holes, write the content for both at that location.
• #155 Fix filling ws-on* event handlers from the server side.

WebSharper.UI v4.1.1

Enhancements

• #144 Reinstate on.event (Element -> #Event -> unit) handlers in WebSharper.UI.Client, instead of always using on.event (Expr<Element -> #Event -> unit>) from WebSharper.UI.Html, to avoid the limitations of quotations.

  It is available when open WebSharper.UI.Client is called after open WebSharper.UI.Html.

WebSharper.UI v4.1.0.38

New features

• #145 Add Lens function to lens into a Var using .V syntax.

  Lens(myvar.V.MyField)
  // is equivalent to:
  myVar.LensAuto(fun x -> x.MyField)

• #146 Add Var<list<T>>.MapLens and .DocLens, similar in functionality to their ListModel counterpart, although with linear-time complexity.

Fixes/enhancements

• #148 Some quotation forms were missing when exploring for captured arguments inside server-side on.* event handlers, including tuple gets (used by F# implicitly when passing captured a tuple value to a client-side function taking a tuple, resulting in a runtime failure). This is now running correctly:

  let t = 1, 2
  div [] [
      button [ on.click (fun _ _ -> Client.TestTuple t) ] [ text "click me" ] 
  ]

• #150 Same as dotnet-websharper/core#881, server-side event handlers that are containing a single call to a static method now do not use a separate pre-compiled function in generated code.
