Final failing message: - ERROR: failed to build: failed to solve: process "/bin/sh -c npm run build" did not complete successfully: exit code: 2 Version/mismatch context: - npm notice: New major version of npm available! 10.8.2 -> 11.11.1 (update suggested: npm install -g npm@11.11.1) - Build base uses node:20-slim, but the issue is missing reveal.js typings during TypeScript build.

- Failing command/step: - [builder 6/6] RUN npm run build - Exact error message and exit code: - plugin/markdown/index.ts(1,15): error TS2614: Module '"reveal.js"' has no exported member 'MarkdownConfig'. Did you mean to use 'import MarkdownConfig from "reveal.js"' instead? - ERROR: process "/bin/sh -c npm run build" did not complete successfully: exit code: 2 - Missing packages or files mentioned: - Missing/incorrect export: MarkdownConfig not exported by the reveal.js module (as TS2614 reports). The tooling suggests an alternative import form. - Version mismatch information: - The build is running reveal.js@6.0.0 (as shown by the log: "reveal.js@6.0.0 build"), while the plugin/markdown code expects a MarkdownConfig export from reveal.js that apparently isn’t present in that version, indicating an API/version mismatch between the markdown plugin and reveal.js.

Summary of tool output (preserves actionable items: file paths, version, commands, package names)
- Core module: reveal.js entry point implemented as a default-exported function taking (revealElement, options).
- Version source: VERSION imported from ../package.json and re-exported.
- Key imports (file paths and module names):
- ./controllers/slidecontent
- ./controllers/slidenumber
- ./controllers/jumptoslide
- ./controllers/backgrounds
- ./controllers/autoanimate
- ./controllers/scrollview
- ./controllers/printview
- ./controllers/fragments
- ./controllers/overview
- ./controllers/keyboard
- ./controllers/location
- ./controllers/controls
- ./controllers/progress
- ./controllers/pointer
- ./controllers/plugins
- ./controllers/overlay
- ./controllers/touch
- ./controllers/focus
- ./controllers/notes
- ./components/playback
- { defaultConfig } from ./config.ts
- * as Util from ./utils/util
- * as Device from ./utils/device
- { SLIDES_SELECTOR, HORIZONTAL_SLIDES_SELECTOR, VERTICAL_SLIDES_SELECTOR, POST_MESSAGE_METHOD_BLACKLIST } from ./utils/constants
- VERSION from ../package.json
- Public API (highlights):
- initialize, configure, destroy, sync, syncSlide
- slide(h, v, f, origin), left/right/up/down, prev/next
- Fragment controls: navigateFragment, prevFragment, nextFragment
- Event API: on, off (plus legacy addEventListener/removeEventListener)
- layout, shuffle, availableRoutes, availableFragments
- toggleHelp, toggleOverview, toggleScrollView, togglePause, toggleAutoSlide, toggleJumpToSlide
- State and persistence: getState, setState
- Progress and indices: getProgress, getIndices, getSlidesAttributes, getSlidePastCount, getTotalSlides
- Slide accessors: getSlide, getPreviousSlide, getCurrentSlide, getSlideBackground, getSlideNotes
- Slides collections: getSlides, getHorizontalSlides, getVerticalSlides
- Feature flags: isFirstSlide, isLastSlide, isLastVerticalSlide, isVerticalSlide, isVerticalStack
- Readiness and environment: isReady, isPaused, isAutoSliding, isOverview, isFocused, isOverlayOpen, isScrollView, isPrintView
- Embedded content: startEmbeddedContent, stopEmbeddedContent
- Plugins: registerPlugin, hasPlugin, getPlugin, getPlugins
- Helpers: getConfig, getRevealElement, getSlidesElement, getViewportElement, getBackgroundsElement
- PostMessage: setup and callback flow; dispatchPostMessage
- Initialization flow (concise): initialize() merges defaults, runtime options, and query hash; supports no-arg init by selecting .reveal; loads plugins then calls start(); returns a Promise that resolves on the 'ready' event.
- Runtime architecture:
- DOM setup and viewport handling (setViewport, layout)
- Multiple view modes: slide presentation, print view, scroll view, overview, fragments
- Auto-slide and auto-animate support
- State management for slides, fragments, and navigation history
- PostMessage support for cross-window API calls (with blacklist)
- Accessibility live region for slide announcements
- Rich API surface exposed via API object and internal Reveal extension
- Plugin system and controller architecture (each controller gets a reference to Reveal)
- Constants and utilities usage (SLIDES_SELECTOR, etc.)
- Notable constants/files used at runtime:
- SLIDES_SELECTOR, HORIZONTAL_SLIDES_SELECTOR, VERTICAL_SLIDES_SELECTOR, POST_MESSAGE_METHOD_BLACKLIST
- defaultConfig
- VERSION
- Notable behaviors:
- Plays well with print/reader modes, RTL, fragments, and responsive scaling
- Supports dynamic resizing, hash-based deep linking, and state restoration
- Exposes a comprehensive programmatic API for navigation, state, and plugin integration
If you want, I can extract a compact call surface (just method names and brief descriptions) or draft a quick usage snippet.index.html react/demo/index.html

- Note
- The file is a TypeScript declaration, with imports/exports for config types from ./config and a default Reveal export.- Library: reveal.js core module. Exports a default function to initialize a presentation and an extensive API. - Version: VERSION imported from ../package.json and exported. - Entry points/files: - Imports controllers: ./controllers/slidecontent, slidenumber, jumptoslide, backgrounds, autoanimate, scrollview, printview, fragments, overview, keyboard, location, controls, progress, pointer, plugins, overlay, touch, focus, notes - Playback component: ./components/playback - Default config: ./config.ts - Utilities: ./utils/util, ./utils/device, ./utils/constants - Version read from package.json for API - Initialization flow: - Supports initialization with no args, one arg (options), or two args (revealElement, options) - Merges defaults: defaultConfig, existing config, options, initOptions, and URL query params - Special case: ?print-pdf sets config.view = 'print' - Loads plugins, then starts - Returns a Promise that resolves on the 'ready' event - Key errors/messages: - "Unable to find presentation root (<div class="reveal">)." - "Reveal.js has already been initialized." - "Unable to find slides container (<div class="slides">)." - Core capabilities exposed by API: - Lifecycle: initialize, configure, destroy, sync, syncSlide - Navigation: slide, left, right, up, down, prev, next (plus RTL and grid variations) - Fragment and playback controls: goto/prev/next fragments, toggleAutoSlide, cueAutoSlide, cancelAutoSlide - View modes: toggleOverview, toggleScrollView, togglePause, isPaused, isAutoSliding - State: getState, setState, getProgress, getIndices, getSlidesAttributes - Slides utilities: getSlides, getHorizontalSlides, getVerticalSlides, hasHorizontalSlides, hasVerticalSlides, shuffle - Rendering/layout: layout, layoutSlideContents, getComputedSlideSize - Events: on, off, dispatchEvent - Plugins: registerPlugin, hasPlugin, getPlugin, getPlugins - Accessibility: announceStatus, getStatusText - PostMessage: setup for cross-window API, dispatchPostMessage - DOM/elements accessors: getRevealElement, getSlidesElement, getViewportElement, getBackgroundsElement - Behavior notes: - Uses a two-phase transform model for layout/overview, responsive sizing, and optional scroll/print views - Manages slide visibility, states, fragments, and embedded content - Provides postMessage bridge when used inside iframes - Primary actions preserved for actionable use: file paths, version, exact error messages, and a clear sense of the public API and initialization workflow.

- Failing command/step:
- Failing step: [builder 7/7] RUN npm run build
- Command output shows: npm run build failed with exit code 2
- Missing packages or files mentioned:
- None explicitly missing; errors indicate API/export mismatches in TypeScript typings rather than missing dependencies.
- Version mismatch / compatibility info:
- Build is using reveal.js@6.0.0 (as shown: "> reveal.js@6.0.0 build").
- Errors suggest API/typing changes vs. plugin code:
- Default export not present in "./Reveal"
- Missing RevealPlugin symbol
- MarkdownConfig not exported from "reveal.js"
- Likely a compatibility/API mismatch between reveal.js 6.0.0 and the plugins or their TypeScript definitions.export { default } from './reveal.js';

- Files
- reveal.js Zoom plugin
- zoom.js 0.3 (modified for reveal.js)
- reveal.js Zoom plugin (Plugin)
- id: 'zoom'
- init(reveal):
- defaultModifier = 'ctrl' on Linux, else 'alt'
- modifier = (reveal.config.zoomKey or defaultModifier) + 'Key'
- zoomLevel = (reveal.config.zoomLevel or 2)
- On reveal element mousedown:
- if event[modifier] and not reveal.isOverview():
- preventDefault()
- zoom.to({ x: event.clientX, y: event.clientY, scale: zoomLevel, pan: false })
- destroy(): zoom.reset()
- zoom.js 0.3 (library)
- Global state: level = 1; mouseX = 0; mouseY = 0; panEngageTimeout = -1; panUpdateInterval = -1
- Detects CSS transform support (supportsTransforms)
- If transforms supported: document.body.style.transition = 'transform 0.8s ease'
- Keyboard: on keyup, if level !== 1 and keyCode === 27 (Escape) -> zoom.out()
- Mouse: on mousemove, if level !== 1 -> update mouseX/mouseY
- magnify(rect, scale):
- center rect in viewport; ensure rect.width/height exist
- If transforms supported:
- if scale === 1 -> reset transform
- else -> set transformOrigin to current scroll offset; apply translate(-rect.x, -rect.y) and scale
- Else (fallback): adjust position/left/top/width/height/zoom or reset when scale === 1
- Update level = scale
- Add/remove 'zoomed' class on documentElement based on level
- pan(): pans the document when cursor nears edges (range 0.12; uses 14/level)
- getScrollOffset(): { x, y } from window.scrollX/pageXOffset and window.scrollY/pageYOffset
- API (returned object):
- to(options):
- If level !== 1 -> zoom.out()
- defaults: options.x = 0, options.y = 0
- If options.element: compute padding=20; derive options.x/y/width/height from element bounds
- If options.width/height set: options.scale = clamp(window.innerWidth / width, window.innerHeight / height, min 1)
- If options.scale > 1:
- options.x *= options.scale; options.y *= options.scale
- magnify(options, options.scale)
- If options.pan !== false: after 800ms start pan at 60fps
- out(): clear pan timers; magnify({x:0,y:0}, 1); level = 1
- magnify(options): alias to to(options)
- reset(): alias to out()
- zoomLevel(): returns level
- Key behaviors and intents
- Press modifier key + left-click (or configured key) to zoom to cursor position at configured scale
- ESC exits zoom (restores 1x)
- Optional element/width/height input allows zooming on a region or element
- Panning can auto-activate after zoom with a delay
- Uses CSS transforms when available; falls back to zoom/positioning if not
- Maintains a 'zoomed’ state class on the document element during zoom
- Licensing and provenance
- zoom.js 0.3 noted as MIT licensed; header mentions original author Hakim El Hattab (lab.hakim.se) with modified for reveal.js
- Actionable items preserved
- File names, plugin id, version 0.3, config keys (zoomKey, zoomLevel), key modifiers, mousedown activation, magnify/to/out/reset/zoomLevel API, element/width/height-based zoom, pan timing and behavior, ESC handling, transform vs fallback behavior.import type { HLJSApi } from 'highlight.js';

const Notes = NotesImplementation as () => NotesPlugin;
export default Notes;
- Purpose: Reveal.js plugin named "notes" to open a speaker notes window and synchronize it with the presentation via postMessage handshake.
- Key dependencies/files:
- Imports speakerViewHTML from './speaker-view.html?raw'
- Imports { marked } from 'marked'
- Uses speaker window title: "reveal.js - Notes"
- Popup size: 1100x700
- Actionable error: alert if speaker view popup fails to open
- Initialization and flow:
- If not a receiver (no ?receiver in URL):
- If URL has ?notes, open speaker window directly.
- Else listen for heartbeat messages to reconnect orphaned speaker window.
- Bind keyboard: S (Speaker notes view) opens the speaker window.
- openSpeakerWindow():
- If speakerWindow exists and open, focus it.
- Else open a new window, assign marked to it, write speakerViewHTML, then connect().
- reconnectSpeakerWindow(reconnectWindow):
- If existing window open, focus it; else set speakerWindow to reconnectWindow, listen for messages, and call onConnected().
- connect():
- Compute presentation URL from deck.getConfig().url or construct from location.
- Start connectInterval (every 500ms) to post a connect message with:
- namespace: 'reveal-notes'
- type: 'connect'
- state: deck.getState()
- url: computed URL
- Add window message listener onPostMessage
- onPostMessage(event):
- Accept only same-origin messages
- If namespace 'reveal-notes' and type 'connected': clear connectInterval; onConnected()
- If type 'call': callRevealApi(data.methodName, data.arguments, data.callId)
- onConnected():
- Register deck event listeners to post state on slide/fragment/overview/paused/resumed/preview events
- Post initial state
- Data flow and messaging:
- post(event):
- Builds messageData with:
- namespace: 'reveal-notes'
- type: 'state'
- notes: string
- markdown: boolean
- whitespace: 'normal' or 'pre-wrap'
- state: deck.getState()
- Notes sources (in priority):
- Slide data-notes attribute (data-notes) → whitespace = 'pre-wrap'
- Fragment: fragment element’s aside.notes (markdown flag via data-markdown)
- Fragment with data-notes attribute
- Aside.notes elements on slide (excluding fragments) → concatenates innerHTML with newlines; markdown flag from first note
- Sends message via speakerWindow.postMessage(JSON.stringify(messageData), '*')
- callRevealApi(methodName, methodArguments, callId):
- result = deck[methodName](...methodArguments)
- Post back: namespace 'reveal-notes', type 'return', result, callId
- isSameOriginEvent(event):
- Compares window.location.origin to event.source.location.origin with try/catch
- Public API:
- id: 'notes'
- init(reveal):
- Sets deck = reveal
- If not a receiver:
- If URL has ?notes -> openSpeakerWindow()
- Else set up heartbeat listener to reconnect on 'heartbeat' from another window
- Add key binding: {keyCode: 83, key: 'S', description: 'Speaker notes view'} to openSpeakerWindow
- open(): openSpeakerWindow
- Notes on behavior:
- Uses postMessage with namespace 'reveal-notes' and types: 'connect', 'connected', 'state', 'return', 'call', 'heartbeat'
- Keeps connection resilient across reloads by heartbeat/reconnect logic
- If popup blocked, shows alert: "Speaker view popup failed to open. Please make sure popups are allowed and reopen the speaker view."

- Failing command/step
- Step: [builder 6/6] RUN npm run build
- Command (simplified): npm run build
The log shows the sequence: > reveal.js@6.0.0 build then > tsc && vite build && vite build -c ... (a long chain of vite builds and a node scripts/add-banner.js dist/reveal.js)
- Missing packages or files mentioned
- Cannot find name 'RevealPlugin' in plugin/highlight/index.ts at line 33, indicating a missing/undefined symbol (likely a missing import/export or type definition).
- Version mismatch info
- Base image used: docker.io/library/node:20-slim (with specific digest). A warning appeared about casing: FromAsCasing: 'as' and 'FROM' keywords' casing do not match (line 3).

Summary of Docker build error
- Failing command/step
- RUN npm run build (builder 6/6)
- Exact error message and exit code
- Exit code: 1 (RUN step failed)
- Error details:
- ✘ [ERROR] No matching export in "vite.config.ts" for import "appendExtension"
- plugin/math/vite.config.ts:3:9:
- import { appendExtension } from '../../vite.config.ts';
- failed to load config from /build/plugin/math/vite.config.ts
- Error: Build failed with 1 error:
- plugin/math/vite.config.ts:3:9: ERROR: No matching export in "vite.config.ts" for import "appendExtension"
- Missing packages or files mentioned
- The build fails due to a missing export: appendExtension is imported from '../../vite.config.ts' in plugin/math/vite.config.ts, but vite.config.ts does not export appendExtension.
- Version information / mismatches
- Used tools: vite v7.3.1
- Base image: node:20-slim
- No explicit version mismatch reported beyond the failing export resolution
- Potential cause (actionable)
- The root cause appears to be that appendExtension is not exported from vite.config.ts, yet plugin/math/vite.config.ts expects it. Inspect and export appendExtension from vite.config.ts or adjust the import to match the actual exports.No files found matching pattern.
No matches found.
