@shadow-garden/bapbong-ui

Framework-agnostic editor UI (L3). Vanilla DOM widgets that mount into a host element and bind to editor.commands — a host framework only supplies the element and calls mount/destroy. The same lib works in Angular, React, Svelte, or plain HTML.

• Scope: scope:app
• Depends on: @shadow-garden/bapbong-contracts only. The editor surface is a structural EditorHandle interface (which BapbongEditor satisfies), and the editor-state type is derived from the Command contract — so this package imports neither the editor nor ProseMirror (same decoupling as the plugin contract).

Toolbar

import { mountToolbar } from '@shadow-garden/bapbong-ui';

const handle = mountToolbar(hostEl, editor);   // renders + wires everything
// …
handle.destroy();                              // removes DOM + listeners

• Renders a button per command from the registry; the lib owns labels/icons (the headless Command carries none), groups, styling and active state.
• Click → command.run(state, dispatch); active/disabled tracked via editor.onChange + command.isActive/isEnabled.
• Customise with { groups, items } — groups reference command names; default is marks then alignments, derived from the registry.
• Theme via CSS variables: --bb-ui-bg, --bb-ui-fg, --bb-ui-border, --bb-ui-hover, --bb-ui-active-bg, --bb-ui-active-fg.

Menubar

import { mountMenubar } from '@shadow-garden/bapbong-ui';

const handle = mountMenubar(hostEl, editor);   // top-level titles → dropdowns
handle.destroy();

• Top-level titles open dropdowns; active toggles show a check. Click-outside / Escape close; hovering another title switches; submenus open on hover.
• Entries are a declarative tree ({ menus, labels }). A MenuEntry is one of:
  • 'separator'
  • { command, label? } — runs a registry command (active check + enabled).
  • { label, run, isActive?, isEnabled?, shortcut? } — a host action (File > Open, View > comment mode, Help…).
  • { label, submenu: MenuEntry[] } — a nested dropdown.
  • { label, widget: (close) => HTMLElement } — custom flyout content.
• tableGridPicker({ maxRows, maxCols, onPick }) — a Word/Docs-style size grid to drop into a widget entry (Insert > Table).

Context menu

import { showContextMenu } from '@shadow-garden/bapbong-ui';

showContextMenu(
  [{ label: 'Cut', run, shortcut: '⌘X' }, 'separator', { label: 'Delete', run, enabled: false }],
  { x: ev.clientX, y: ev.clientY },
);

• A floating menu at a viewport point (one-shot rows + separators). Viewport- clamped; closes on select / outside click / Escape / scroll; only one open at a time. The host builds the entries from the editor's contextmenu pointer event (position + target).

Dialog

A generic overlay primitive (built on the native <dialog> — modal mode gets focus-trap / Esc / backdrop for free). Reused by find, prompts, shortcuts, and the cell-properties dialog — one primitive, not N bespoke widgets.

import { Dialog, promptDialog } from '@shadow-garden/bapbong-ui';

const dlg = new Dialog({ title: 'Cell properties', modal: true });
dlg.setContent(myFormElement);
dlg.open();                                  // open() / close() / onClose() / destroy()

const url = await promptDialog({ title: 'Insert link', placeholder: 'https://…' });

Pass { anchor: () => el.getBoundingClientRect() } to pin a non-modal dialog's top-right just inside a rect (e.g. the canvas viewport) instead of the screen corner; it re-positions on scroll/resize.

Find dialog

import { createFindDialog } from '@shadow-garden/bapbong-ui';

const find = createFindDialog(editor.find);  // bound to the find plugin
find.open();   // e.g. from an Edit ▸ Find menu item / Ctrl+F
find.destroy();

• Find/replace inside a (non-modal) Dialog, bound to a structural FindHandle (the editor's find plugin satisfies it), so the package never imports the editor. Query input, match count, prev/next, replace + replace-all; closing clears the search. i18n via { labels }.
• Opens on Ctrl/Cmd+F (pre-empting the browser's native find); disable with { shortcut: false }. Pin it with { anchor } (see Dialog).
