pandoc 3.10.1

on GitHub

New output format t2t (Txt2Tags markup, https://txt2tags.org)) (luginf).

New module Text.Pandoc.Writers.Txt2Tags, exporting writeTxt2Tags (loginf) [API change]. Also exported from Text.Pandoc.Writers.

Change adding of .yaml extension in --defaults option (#11717). Previously it was always added if the specified filename lacked an extension. Now it is only added if there is no file with the original name. This facilitates using --defaults with bash/zsh <(..) or =(..).

RST reader:

• Fix nested placeholder resolution for inline elements (#11753, Tobias Deiminger). (Regression from pandoc 3.6.)
• Treat undefined substitution references as plain text (#11727). This mirrors rst2html behavior.

Markdown reader:

• Ordered sublists must start with 1, er equivalent, e.g. i (#11735). This brings the markdown parser in line with commonmark, and avoids a lot of unintended list starts. Note that ordered lists that are not sublists may still start with numbers other than 1.

ODT reader:

• Don’t create Emph just because of changed font (#11691).

RTF reader:

• Support multi-paragraph list items.
• Support legacy \pn/\pntext paragraph numbering (#11686).

Docx reader:

• Improve horizontal rule detection (#11689).
• Key list numbering off abstractNumId, fixing numbering for restarted lists (#8367).

LaTeX reader:

• Handle \hypertarget with one braced parameter (#7418).

DokuWiki reader:

• Skip non-cell content after table row (#11739).

Typst reader:

• Support auto_identifiers extension (#11041). The extension is available for the typst reader but is off by default; enable it with -f typst+auto_identifiers. The related gfm_auto_identifiers and ascii_identifiers extensions are also made available.
• Recognize divider() for horizontal rule (#11540).

HTML reader:

• Fix unused variable warning in CI (#11704, Robertas).
• Strip language- from all classes, not just first (#11701). Also combine classes from both code and pre class if they are nested.

Powerpoint writer:

• Keep tables and surrounding text on same slide (#11433, Chris Callison-Burch). Previously, when a slide contained bullet points before and after a table, content would be split across multiple slides or use a two-column layout that didn’t preserve the source order.

Texinfo writer:

• Fix spacing bug around HorizontalRule (#11749).
• fix escaping in links (#11758). Previously we dropped periods, commas, etc. This was a regression from 2024. All we really need to do is escape the comma.

LaTeX writer:

• Provide a way to use table instead of longtable (#1023). When the float class is attached to a table, a standard floating table will be generated instead of a longtable. Placement can be specified via the latex-placement attribute. This will help, especially, those who use two-column layouts, since longtable is incompatible with these.
• Fix footnotes in definition list headings (#8240).

Markdown writer:

• Fix ordered list indentation bug (#11762).
• Improve identification of code language class by looking it up in the syntax map (#11701).
• In YAML metadata, put double quotes around strings that are numbers beginning with 0 or ending with 0 and having a decimal point (#11715). Otherwise they will read as YAML numbers and potentially be modified (e.g. 3.10 -> 3.1).

Docx writer:

• Use namespace URI instead of prefix in extractPageLayout (#11697, Robertas).

ODT writer:

• Use starmath for math. This improves appearance and editability of equations. The main code changes are due to @jdpipe (#11470).
• Image anchoring, percent dimensions, text width resolution (#11746, Can H. Tartanoglu). Inline images now emit text:anchor-type=as-char on their draw:frame, anchoring the frame as a character so it flows with the surrounding text. When both width and height are given and the width is a percentage, the width is now resolved against the reference document text area width, mirroring how the docx writer derives its print width from the reference docx section properties. The height follows the aspect ratio.

RTF writer:

• Emit real RTF lists with a list table. Lists were written as plain paragraphs with a literal marker and a hanging indent, carrying none of the \ls/\ilvl references or the \listtable/\listoverridetable that the RTF list model (and pandoc’s own reader) expect, so lists could not round-trip.
• Allow fontsize to be specified (#11750). The fontsize is specified in a variable or metadata field and passed through the renderer via a Reader monad.

Typst writer:

• Fold lang into pickTypstAttributes (#11673). This ensures that lang attributes will be set for both Divs and Spans.
• Add support for tight terms in Typst writer (#11748, Amir Dekel). This just affects whether a blank line is emitted in the markup. Note that pandoc’s default template contains a show rule for terms that will make these blank lines irrelevant, but this change allows one to use tight lists with custom templates.
• Further tight term list improvements. For tight list items consisting of just one Plain block, we no longer create a #block for the definition; this allows it to remain on the same line as the term.
• Emit divider() as horizontal rule (#11540).

LaTeX template:

• The caption package is included and a default spacing set between the caption and the table.

Typst template:

• Remove custom show rule for terms. Instead, we use a set rule to set hanging-indent.
• Remove old horizontalRule definition from default template.
• Polyfill divider for typst < 0.15.
• Allow multiword keywords (#11730, Albert Krewinkel). Typst expects single words as keywords, so keywords consisting of multiple words must be quoted (and should not be wrapped).

HTML template:

• Remove hard-coded font-size for print CSS. Print CSS now uses the inherited font-size.

epub.css:

• Get rid of obsolete #TOC rules (#11747). We don’t generate anything with the TOC id in epubs. A table of contents is in nav#toc and we have rules for that.
• Put clause for all headings before individual h1, h2, … (#11742). This is more logical, since the individual clauses are meant to override.

Text.Pandoc.Shared:

• Improve makeSections (#11745). Previously it would sometimes create doubled section divs. By leaving the inner heading’s id on the heading itself, and then consolidating the inner and outer section divs, we can avoid this undesirable result.
• taskListItemToAscii: handle empty task list case.
• taskListItemFromAscii: handle empty task list case (#11599, Chirag Dhamange).

Text.Pandoc.App.CommandLineOptions:

• Use optCSL and optBibliography from Opt (#11741). Previously we set optMetadata directly, but that had some unintended effects, especially in interacting with defaults files. With this change, a --csl on the command line can override one set in a prior defaults file.

Text.Pandoc.App:

• Enable auto_identifiers when a table of contents is requested (#11041). Table-of-contents entries link to heading identifiers, so when --toc/--table-of-contents is given, force the auto_identifiers extension on for the input format even when it is off by default (as it now is for typst). This makes typst-to-markdown --toc produce working links.

Text.Pandoc.Writers.Shared:

• htmlAttrs - don’t add data- prefix for markdown (#11685). This is necessary for the markdown_attribute extension to work properly.

Ensure that IO error messages go to stderr (#11710).

Use emojis 0.1.5, texmath 0.13.2,typst 0.11, typst-symbols 0.3, pandoc-types 1.23.1.2, djot 0.1.4.1, commonmark-extensions 0.2.7.1, skylighting-format-blaze-html 0.1.2.1.

Add Makefile rule to update all-cabal-hashes in flake.lock.

MANUAL.txt:

• Clarify comment about table types (#11719).
• Small clarification in image section (#11760).
• Rewrite “A note on security.” Clarify the risks of using pandoc in a web service and explain how to do so more safely. Note some specific vulnerabilities with the pdf-engine wkhtmltopdf. This incorporates the suggestions made in #11262 and also benefits from a report by Kai Aizen.
• Clarify native_numbering extension (#11599).
• Include Lua filter to set float attribute on tables.
• Clarify expectations for EPUB metadata (#11723).
• Improve instructions for specifying EPUB identifier (#11723).
• Fix typo (#11720, Scott Talbert).

Fix typo in lua-filters.md (#11724, Enrico Spinielli).

Revamp flake.nix to use haskell.nix (#11707). This allows the project to be built using nix build and run using nix run. @srid deserves credit for most of this. stack.yaml is used as a source of truth for the versions to use, including for git repositories.

Change symlink to regular file for COPYING.md in pandoc-cli, pandoc-lua-engine, pandoc-server.
