Walkthrough

The pull request expands BitRichTextEditor with editing APIs, mentions, grouped emoji search, enhanced find and replace, link, image, and table workflows, accessibility support, iframe sanitization, demos, and bridge contract tests.

Changes

Rich text editor improvements

Layer / File(s) Summary
Component state and editor APIs
src/BlazorUI/Bit.BlazorUI.Extras/Components/RichTextEditor/*.cs
The component adds public editing and count APIs, selection state, effective read-only handling, panel focus management, keyboard shortcuts, find navigation, link and image editing, table input, and setup options.
JavaScript bridge and sanitization contracts
src/BlazorUI/Bit.BlazorUI.Extras/Components/RichTextEditor/BitRichTextEditorJsRuntimeExtensions.cs, .../BitRichTextEditor*Policy*.cs, .../BitRichTextEditor.Sanitization.cs
Interop methods carry link, image, table, find, selection, content, color, and mention operations. Sanitization supports iframe host allowlists and expanded markup attributes.
Mention contracts and interaction
src/BlazorUI/Bit.BlazorUI.Extras/Components/RichTextEditor/BitRichTextEditor.Mentions.cs, .../BitRichTextEditorMention.cs
Mention suggestions use asynchronous lookup with stale-response protection, keyboard navigation, escaped HTML insertion, callbacks, and focus handling.
Toolbar panels and editor surface
src/BlazorUI/Bit.BlazorUI.Extras/Components/RichTextEditor/BitRichTextEditor.razor, .../BitRichTextEditor.scss, .../*.Emoji.cs
The rendered surface adds grouped emoji search, mention and quick-selection toolbars, table controls, expanded formatting controls, accessibility attributes, image operations, and styles for the new editor states.
Documentation examples and bridge validation
src/BlazorUI/Demo/Client/.../RichTextEditor/*, src/BlazorUI/Tests/.../RichTextEditor/*
The demo documents new parameters and APIs and adds localization, selection, mention, smart typography, quick-toolbar, and RTL examples. Contract tests compare C# bridge declarations with the TypeScript bridge.

Merge Risk: 🟡 Moderate · up to 36b9b

Several editor interactions can retain stale state, bypass disabled-state expectations, or suppress an expected browser shortcut without performing an editor action. These issues should be resolved before merging the expanded editor workflow.

141-146: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Include default JSInvokable identifiers in both contract checks.

EveryJsInvokableCallbackIsCalledByTheBridge and TheBridgeCallsNoCallbackTheComponentDoesNotExpose discard methods whose JSInvokableAttribute.Identifier is null. For [JSInvokable], the effective identifier is the method name. Resolve each identifier as attribute.Identifier ?? method.Name. The current component uses explicit identifiers, but this omission leaves default identifiers unchecked.

Proposed reflection query
 var declared = typeof(BitRichTextEditor)
     .GetMethods(BindingFlags.Public | BindingFlags.Instance)
-    .Select(m => m.GetCustomAttribute<JSInvokableAttribute>()?.Identifier)
-    .Where(id => string.IsNullOrEmpty(id) is false)
+    .Select(m => (Method: m, Attribute: m.GetCustomAttribute<JSInvokableAttribute>()))
+    .Where(item => item.Attribute is not null)
+    .Select(item => item.Attribute!.Identifier ?? item.Method.Name)

Inline comments:
In
`@src/BlazorUI/Bit.BlazorUI.Extras/Components/RichTextEditor/BitRichTextEditor.Find.cs`:
- Around line 57-58: Update the invalid search-term rejection path in the find
flow to await ClearFindAsync() before returning, after resetting the find state
and before raising the invalid-term error, so highlights from the previous valid
search are removed.

In
`@src/BlazorUI/Bit.BlazorUI.Extras/Components/RichTextEditor/BitRichTextEditor.Links.cs`:
- Around line 98-100: Update NormalizeLinkUrl to distinguish a numeric host port
from a URI scheme: for values like example.com:8443/docs, continue normalization
so the URL receives the expected HTTP(S) scheme, while preserving unchanged
handling for actual schemes. Add coverage for bare host-plus-port URLs and
ensure IsAcceptableLinkUrl accepts them.

In
`@src/BlazorUI/Bit.BlazorUI.Extras/Components/RichTextEditor/BitRichTextEditor.Mentions.cs`:
- Around line 60-67: Update the mention-search cancellation and completion flow
around CloseMention and the catch/success handling in the mention search method
so every closed or superseded search is invalidated before it can update state
or raise an error. Ensure the current token is advanced or otherwise marked
stale when closing, and apply the token check to the failure path as well as the
success path, preventing obsolete searches from repopulating _mentionItems or
reporting errors.

In
`@src/BlazorUI/Bit.BlazorUI.Extras/Components/RichTextEditor/BitRichTextEditor.razor`:
- Line 280: Update the source-view textarea and source-view button to honor
IsEnabled: use a disabled state for the textarea instead of relying solely on
EffectiveReadOnly, and prevent the button from being enabled when IsEnabled is
false even if _inSourceView is true. Preserve normal source-view behavior while
the component is enabled.

In
`@src/BlazorUI/Bit.BlazorUI.Extras/Components/RichTextEditor/BitRichTextEditor.razor.cs`:
- Line 243: Update the reset/update logic around the `next == _currentHtml`
guard to compare `next` with the live editor content from `GetHtmlAsync()`
rather than the potentially stale `_currentHtml`, or always perform the explicit
replacement. Ensure caller resets replace newer DOM content even when the
debounced `OnContentChanged` callback has not run.

In
`@src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Extras/RichTextEditor/BitRichTextEditorDemo.razor`:
- Line 521: Update the live demo callback in BitRichTextEditorDemo.razor and the
example30RazorCode callback in BitRichTextEditorDemo.razor.cs at lines 521-521
and 1047-1047 to use Task-returning wrappers that await
apiEditor.SelectAllAsync(), rather than invoking the ValueTask without awaiting
it.

In
`@src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Extras/RichTextEditor/BitRichTextEditorDemo.razor.cs`:
- Line 1047: Update the SelectAllAsync button handlers in both the published and
live examples to use async lambdas returning Task, and await
apiEditor.SelectAllAsync() instead of discarding its ValueTask. Locate the
handlers by the SelectAllAsync button and preserve the existing button behavior.
