Releases

v0.14.0

  • Increase code font size by 50%.
  • Add support for includes using ![[path]] syntax.
  • Add bake presently:rehearse tasks for updating timing information.

v0.13.0

  • Change zoom to 50% on slide preview (presenter display).

v0.12.0

  • Add support for translation to code slide.

v0.11.0

  • Add Slide#element and SlideContext#element getters — expose the slide body DOM element directly for cases where find() is not sufficient, such as measuring dimensions, attaching event listeners, or integrating third-party libraries.

v0.10.0

  • Replace internal SlideChain with an exported SlideContext class. SlideContext accumulates elapsed time across after() calls exactly as SlideChain did, but also exposes find(), setTimeout(), and a get elapsed() getter. Slide#after() now returns a SlideContext — existing slide scripts are unaffected.
  • Add Slide#loop(callback, {delay}) — runs a callback in a repeating loop until the slide changes. The callback receives a fresh SlideContext each iteration so it can schedule steps with after(). The loop waits for all steps to complete (context.elapsed) plus an optional extra delay before starting the next iteration. All timeouts flow through the slide's existing tracked setTimeout, so they are cancelled automatically on slide change.

v0.9.0

  • SlideBuilder#show and SlideBuilder#next no longer overwrite view-transition-name on elements that already have one set. This allows elements with explicit names (for morph transitions to other slides) to coexist with the build system — they still get visibility and viewTransitionClass managed, but keep their own name.

v0.8.0

  • Add optional translation section to the default template.

v0.7.0

  • Rework build effects to use direct CSS class animation rather than view-transition-class. build-fade, build-fly-up, etc. are now regular @keyframes classes applied to the revealed element, rather than view transition pseudo-element selectors. This decouples in-slide sequential animation from slide-level morph transitions.
  • Rename SlideElements#build to SlideElements#show for clarity — boxes.show(0) / boxes.show(3) more clearly describes the outcome from the audience's perspective.
  • Add SlideElements#builder(options) — returns a SlideBuilder with default options (group, effect) and a cached position, so callers can use next() instead of tracking the step count manually.
  • Add SlideBuilder#show(count, overrides) — set visibility state to an arbitrary position. Returns a Promise that resolves when the reveal animation completes (or immediately when no effect is given).
  • Add SlideBuilder#next(overrides) — reveal the next element with the builder's default effect, optionally overridden per call. O(1): only touches the single newly revealed element. Returns a Promise.
  • Add SlideBuilder#play(interval, callback) — reveals all remaining elements in sequence with interval milliseconds between each. An optional callback is invoked after each reveal; return false to stop playback early. Requires the builder to be created via slide.find(...).builder() so timeouts are tracked and cancelled on slide change.
  • Add SlideBuilder#finished getter — returns true when all elements have been revealed.
  • Add Slide#after(delay, callback) — schedules a callback after a delay in milliseconds and returns a SlideChain. Subsequent .after(delay, callback) calls on the chain fire relative to the previous step, making sequential reveal timing easy to read and adjust.
  • Add Slide#setTimeout(callback, delay) — a tracked replacement for the global setTimeout. All timeouts registered this way are automatically cancelled when the slide changes, preventing stale callbacks from firing after navigation. The global setTimeout in slide scripts is shadowed by this method automatically.
  • Add Slide#cancelTimeouts() — cancels all pending timeouts registered by the slide's script. Called automatically by the presentation engine on every slide change.

v0.6.0

  • Add bake presently:slides:speakers task to print a timing breakdown grouped by speaker. Each speaker's slides are listed in presentation order with individual and total durations, making it easy to balance talk time in multi-speaker presentations. Slides without a speaker key are grouped under (no speaker).

v0.5.0

  • Add optional speaker front matter key to slides. When present, the current speaker's name is shown in the timing bar. If the next slide has a different speaker, a handoff indicator (e.g. → Next Speaker) is shown alongside, giving presenters an at-a-glance cue for tag-team talks.

v0.4.0

  • Add bake presently:slides:notes task to extract all presenter notes into a single Markdown document, with each slide's file path as a heading. Useful for reviewing or sharing speaker notes outside of the presentation.
  • Presenter notes are now kept as a Markdown AST internally and rendered to HTML on demand, so the notes you write are faithfully round-tripped rather than converted to HTML at parse time.

v0.3.0

  • Add diagram template with a position: relative container — direct <div> children are position: absolute by default for free-form layouts.
  • All slide templates now have position: relative on the slide inner container, allowing absolutely positioned overlays in any template.
  • Add slide scripting: a fenced ```javascript ``` block at the end of presenter notes is extracted and executed in the browser after each slide renders. The script receives a slide object scoped to the slide body.
  • Add Slide#find(selector) — a pure CSS selector query returning a SlideElements collection with no side effects.
  • Add SlideElements#build(n, options) — shows the first n matched elements, hides the rest, and assigns view-transition-name for morph transition matching. Accepts group (name prefix) and effect (entry animation) options.
  • Add build effects via view-transition-class: fade, fly-left, fly-right, fly-up, fly-down, scale. Requires Chromium 125+; degrades gracefully to instant appear in other browsers.
  • Rename magic-move transition to morph.
  • Italic text in presenter notes is styled in amber to distinguish stage directions from spoken words.
  • Add transitions guide and animating slides guide to documentation.

v0.2.0

  • Use Markly's native front matter parser (Markly::FRONT_MATTER) instead of manual string splitting, parsing each slide document once and extracting front matter directly from the AST.
  • Use the last --- hrule in the AST as the presenter notes separator, so earlier --- dividers in slide content are preserved correctly.
  • Add support for Mermaid diagrams in slides.

v0.1.0

  • Initial release.
  • Slide files are Markdown with YAML front matter for metadata (template, duration, title, skip, marker, transition, focus).
  • Slide content is split into named sections by top-level headings, rendered to HTML via Markly.
  • Presenter notes are separated from slide content by a --- divider.
  • Magic move transitions between slides.
  • Navigation control in the presenter view.
  • Code highlighting with line-range focus support.
  • Live state synchronisation between display and presenter views over WebSockets.
