Fixes: - Support Unicode in attributes. (reported by @andreiborisov in #605, fixed by @witiko in #608) Development: - Add `\mmdcCommand` macro for configuring the command used to render Mermaid diagrams. (suggested by @TheManchineel in #613, added by @witiko in #614) For example, you can use different icon packs as follows: ```` tex \documentclass{article} \def\mmdcCommand{mmdc --iconPacks '@iconify-json/logos'} \usepackage[import=witiko/diagrams@v2]{markdown} \begin{document} \begin{markdown} ``` mermaid architecture-beta group api(logos:aws-lambda)[API] service db(logos:aws-aurora)[Database] in api service disk1(logos:aws-glacier)[Storage] in api service disk2(logos:aws-s3)[Storage] in api service server(logos:aws-ec2)[Server] in api db:L -- R:server disk1:T -- B:server disk2:T -- B:db ``` \end{markdown} \end{document} ```` - Add a new Lua option `htmlOverLinks` that causes HTML tags to be recognized as tags rather than hyperlinks when the Lua option `relativeReferences` has been enabled. (discussed with @u-fischer in #597, added by @witiko and @lostenderman in #607) The option `htmlOverLinks` is an experimental option: Whenever the option `experimental` is enabled and `htmlOverLinks` is unspecified, it will also be enabled. Like other experimental options, `htmlOverLinks` will be enabled by default in the next major release of the Markdown package and soft-deprecated. - Add a new Lua option `blankBeforeHtmlBlock` that causes the parser to require a blank line between a paragraph and the following CommonMark HTML block. (discussed with @u-fischer in #598, added by @witiko and @lostenderman in #608) Enabling this option breaks CommonMark compliance but makes it easier to write raw HTML such as inline HTML comments without producing HTML blocks by accident. - In theme `witiko/diagrams`, add parameter `format` for GraphViz diagrams. (reported by @witiko in #611, fixed by @witiko in #612) Here is an example LaTeX document using the new parameter: ```` tex \documentclass{article} \usepackage[import=witiko/diagrams@v2, relativeReferences]{markdown} \begin{document} \begin{markdown} ``` dot {caption="An example directed graph" format=svg width=12cm #dot} digraph tree { margin = 0; rankdir = "LR"; latex -> pmml; latex -> cmml; pmml -> slt; cmml -> opt; cmml -> prefix; cmml -> infix; pmml -> mterms [style=dashed]; cmml -> mterms; latex [label = "LaTeX"]; pmml [label = "Presentation MathML"]; cmml [label = "Content MathML"]; slt [label = "Symbol Layout Tree"]; opt [label = "Operator Tree"]; prefix [label = "Prefix"]; infix [label = "Infix"]; mterms [label = "M-Terms"]; } ``` See the diagram in Figure <#dot>. \end{markdown} \end{document} ```` This can be used to circumvent missing support for PDF output in some distributions of GraphViz, [notably Debian Forky][bugs-debian-1123051], which the `texlive/texlive` Docker images are currently based on. [bugs-debian-1123051]: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1123051 Defaults: - In LaTeX, fix header attribute `{-}` for chapters and parts. (reported by @MacLotsen in #602, fixed by @witiko in e588d205) - In LaTeX, reset category codes before using `\maketitle`. (reported by @MacLotsen in #603, fixed by @witiko in 00068c87) Continuous integration: - Bump `actions/checkout` from 5 to 6. (added by @dependabot in #604)
