Changelog

What changed, and when.

Every released version of the prism extension, and what each one changed.

0

fix: Read warn-on-drop through the schema, so a value that is not a boolean is reported rather than ignored. Comparing the document text left every spelling but true silent, including the mistake itself. (#27)
fix: Report a key nested inside an option as a warning rather than an error, so one nested typo does not invalidate the whole configuration. This matches how the extension already reports an unknown key at the top of its own block. (#27)

docs: Serve the extension’s social card as the Open Graph image, so a shared link shows the card rather than the first image on the page. (#24)

build: Update the vendored Lua modules to 2.3.0, which includes the schema-check fix for an extension whose entry points are in a subdirectory. A module no longer carries a version line in its header, so its checksum changes only when its code changes. (#25)
build: Fetch the schema validator from a Quarto Wizard release asset rather than a raw path inside its repository, which a refactor could move without notice. The vendored file is unchanged. (#26)
build: Update the vendored Lua modules to 2.5.0, which adds the accessor that reads what the schema resolves an option to. The schema validator moves to its own release train and is pinned at schema-v2.2.0, which accepts only true and false as a boolean. (#27)

feat: Check the document configuration against the extension schema and report what it does not accept. (#20)

fix: Raise quarto-required to >=1.9.38. The extension manifest registers the filter at pre-ast, and the _extension.yml schema only accepts a filter entry point from that version; below it the render fails validation.
fix: Leave the typst: attributes Pandoc reads itself untouched in a Typst render, rather than stripping their prefix and losing the styling. On a div those are typst:text:<property> and the thirteen parameters of Typst’s block(): width, height, breakable, fill, stroke, radius, inset, outset, spacing, above, below, clip, and sticky. On a span only typst:text:<property> is read, and on a code block or a heading nothing is, so prism keeps those. The reserved keys now work alongside a promoted typst:style on the same element, and the split follows Typst property output. Applies whenever Pandoc writes Typst, including under a custom format.

docs: Add a documentation website under docs/, built on the atelier project type and published to https://m.canouil.dev/quarto-prism/, with a Typst rendering of the same source so both branches of a prefix can be compared.
docs: Trim README.md to a landing page pointing at the website, and example.qmd to a short starting point to copy.
docs: Add the Pages workflow, which renders docs/ on pull requests and deploys it from the release tag.
docs: Add the Quarto Extensions Updates workflow, scanning docs for the website’s own dependencies.

fix: move lua filter to pre-ast to ensure it runs before any filters (e.g., cascade).

feat: Resolve format-prefixed attributes on headings (## Heading {html:style="..."}), matching the existing behaviour on Div, Span, and CodeBlock elements.

feat: Add the extensions.prism.warn-on-drop option (default false) which emits a quarto.log.warning each time a format-scoped attribute is dropped because no prefix matched the active target format; useful to surface typos in prefixes that would otherwise vanish silently.

docs: Document the final attribute output order (kept then promoted, source-order tiebreak) and the behaviour of unknown prefixes (treated as non-matching and dropped).
docs: Add an explicit precedence table (exact > alias > default > unprefixed) and a worked example for the conflict case where a static unprefixed value coexists with format-scoped and default values for the same attribute name.

refactor: Extract the HTML slide-format set into the shared _modules/slide-formats.lua module so prism and portable-links agree on what counts as a slide format; the canonical source lives in mcanouil-skills/skills/creating-quarto-extension/assets/modules and is copied into each extension on release.

feat: Add the slide format-group alias, which matches every HTML slide format (revealjs, slidy, s5, dzslides, slideous), so a single prefix can target the whole group.
feat: Add the default:name fallback prefix, applied only when no format-specific variant of the same attribute name matched the active format.

feat: Initial release of the prism filter, promoting format:name attributes on Div, Span, and CodeBlock elements when the prefix matches the active rendering format.
