On Android, intercept paste actions before BasicTextField's plain-text
handler and route clipboard content through the existing HTML pipeline:
• ClipData.Item.htmlText → used directly (Chrome, Docs, Gmail, …)
• ClipData.Item.text is Spanned → converted via android.text.Html.toHtml()
(covers AppCompatEditText copies carrying StyleSpan, UnderlineSpan,
URLSpan, ForegroundColorSpan, StrikethroughSpan, etc.)
• Plain text (no spans) → returns false, default paste flow unchanged
Two intercept points are wired up:
- SpannedPasteTextToolbar wraps LocalTextToolbar to catch the
context-menu "Paste" action.
- onPreviewKeyEvent intercepts Ctrl+V / Cmd+V on hardware keyboards.
All non-Android targets receive a no-op actual that returns false.
The skipSigning Gradle property is added to module.publication.gradle.kts
to allow unsigned publishToMavenLocal builds during local development.
Also merges upstream PR MohamedRejeb#638 (fix StringIndexOutOfBoundsException in
MarkdownUtils for nested indented lists).

The previous implementation only covered two paste paths: • Long-press → context menu "Paste" (TextToolbar wrapper) • Hardware keyboard Ctrl/Cmd+V (onPreviewKeyEvent) Soft-keyboard IME paste (the "Paste" button in the IME toolbar or suggestion strip) goes through InputConnection.performContextMenuAction, which calls ClipboardManager.getText() directly — bypassing both of the above intercept points, causing plain-text to be inserted. Fix: RichTextClipboardManager.getText() now calls SpannedPasteHandler.readHtml() (new method). When HTML or Spanned content is found in the platform ClipData, it stores the HTML in RichTextState.pendingHtmlPaste and returns the plain-text fallback so the IME gets a valid cursor position. RichTextState.onTextFieldValueChange() consumes pendingHtmlPaste at its very top — before handleAddingCharacters runs — and replaces the would-be plain-text insertion with a proper insertHtmlAfterSelection() call. This path is also taken for TextToolbar / Ctrl+V pastes, but those are intercepted earlier (tryPasteSpanned) and never reach onTextFieldValueChange with pendingHtmlPaste set. All paste paths now preserve formatting: • Soft keyboard IME paste ← new • Context menu paste ← existing, still works • Hardware Ctrl/Cmd+V ← existing, still works • Plain text (no spans) ← falls through unchanged Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…Pasteboard - Add getHtmlIfMatch(addedText) to SpannedPasteHandler interface so onTextFieldValueChange can probe the clipboard when the IME paste button bypasses RichTextClipboardManager.getText() entirely - Implement getHtmlIfMatch in AndroidSpannedPasteHandler: compares the added text against clipboard plain text; returns HTML if they match - Replace iOS no-op with IosSpannedPasteHandler backed by UIPasteboard.generalPasteboard, covering all three paste paths: context menu (tryPasteSpanned), hardware keyboard (tryPasteSpanned), and soft keyboard / IME (getHtmlIfMatch) - Wire spannedPasteHandler into RichTextState via SideEffect so onTextFieldValueChange has access to the platform handler - Add PasteDebugLog expect/actual for all platforms (RichPaste tag) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
iOS clipboard HTML carries the source page's background-color (usually white or transparent) on every span. Strip white/#fff/rgb(255,255,255)/ rgba(255,255,255,*) and transparent values so they don't render as white boxes behind text in the editor. Intentional highlight colors are left intact.
