From ebdd437f0af8f2db8f93b5f1204bde0aa79777b1 Mon Sep 17 00:00:00 2001 From: Jon Kinney Date: Sat, 28 Mar 2026 04:16:11 -0500 Subject: [PATCH 01/11] Add block-based editing: selection, drag-and-drop, and actions menu Block selection via drag handle click or Cmd+click with multi-select via Shift+click and Shift+Arrow. Visual feedback with highlight color inheritance that cascades to children on indent/move/drop. Drag and drop with depth-aware drop indicators, self-outdent from any nesting level, and wrapped block support. Drop targets calculate correct nesting depth based on cursor position. Block actions menu (Cmd+/) with duplicate, delete, and turn-into operations. Tab/Shift+Tab indent/outdent in block-select mode. Keyboard block movement with Cmd+Shift+Arrow. Reactive block-handles attribute allows showing/hiding drag handles at runtime. Public hasBlockSelection getter exposes block-select mode to consuming applications.

Fix decorator click interceptor to allow NodeDeleteButton clicks through by excluding lexxy-node-delete-button from event suppression. Update HR delete test to use block-select + Backspace instead of clicking the delete button (block editing changes HR click behavior).

Previously, children were orphaned as siblings when the parent promoted out, allowing subsequent moves to pass the parent through its own children. Add regression tests for repeated Cmd+Shift+Arrow movement: - Parent moving down never passes through its children - Child moving up preserves order relative to siblings Co-Authored-By: Claude Opus 4.6 (1M context) --- src/extensions/block_selection_extension.js | 6 + .../block_movement_hierarchy.test.js | 183 ++++++++++++++++++ 2 files changed, 189 insertions(+) create mode 100644 test/browser/tests/block_editing/block_movement_hierarchy.test.js diff --git a/src/extensions/block_selection_extension.js b/src/extensions/block_selection_extension.js index 9d49241ca..07319e4d3 100644 --- a/src/extensions/block_selection_extension.js +++ b/src/extensions/block_selection_extension.js @@ -1424,8 +1424,14 @@ export class BlockSelectionExtension extends LexxyExtension { // Can't break out upward if at document start. if (!isDown && !currentList.getPreviousSibling()) return + // Carry the node's children (structural wrapper) along when promoting + const ownWrapper = this.#getOwnStructuralWrapper(node) + const newList = $createListNode(currentList.getListType()) newList.append(node) + if (ownWrapper) { + newList.append(ownWrapper) + } if (isDown) { currentList.insertAfter(newList) diff --git a/test/browser/tests/block_editing/block_movement_hierarchy.test.js b/test/browser/tests/block_editing/block_movement_hierarchy.test.js new file mode 100644 index 000000000..bb4fe2617 --- /dev/null +++ b/test/browser/tests/block_editing/block_movement_hierarchy.test.js @@ -0,0 +1,183 @@ +import { expect } from "@playwright/test" +import { test } from "../../test_helper.js" +import { normalizeHtml } from "../../helpers/html.js" + +function stripDynamicAttrs(html) { + return html + .replace(/\s*data-bullet-depth="[^"]*"/g, "") + .replace(/\s*data-list-item-type="[^"]*"/g, "") +} + +async function assertBlockHtml(editor, expected) { + await expect + .poll( + async () => { + await editor.flush() + return stripDynamicAttrs(normalizeHtml(await editor.value())) + }, + { timeout: 5_000 }, + ) + .toBe(stripDynamicAttrs(normalizeHtml(expected))) +} + +const modifier = process.platform === "darwin" ?
