  • Add interface for custom readers written in Lua (#7669). Users can now do -f myreader.lua and pandoc will treat the script myreader.lua as a custom reader, which parses an input string to a pandoc AST, using the pandoc module defined for Lua filters. A sample custom reader can be found in data/creole.lua. Also see documentation in doc/custom-readers.md.

  • New module Text.Pandoc.Readers.Custom, exporting readCustom [API change].

  • Allow plain to be used in raw attribute syntax.

  • Accept empty --metadata-file (#7675). This was a regression from 2.15 behavior.

  • Markdown reader: Improve inlinesInBalancedBrackets. This is just a small improvement in terms of performance, but it’s simpler and more direct code. Also, we avoid parsing interparagraph spaces in balanced brackets, as the original did.

  • BibTeX reader: Properly handle commented lines in BibTeX/BibLaTeX (#7668).

  • RST reader: handle class attribute for for custom roles (#7699, willj-dev). Previously the class attribute was ignored, and the name of the role used as the class.

  • DocBook reader:

    • Add <titleabbr> support (Rowan Rodrik van der Molen).
    • Support for <indexterm> (#7607, Rowan Rodrik van der Molen).

  • LaTeX reader:

    • Add rudimentary support for \autoref (#7693).
    • Add ‘uri’ class when parsing \url, for consistency with treatment of autolinks in other formats (#7672).

  • JATS reader: Capture alt-text in figures (#7703, Aner Lucero).

  • MediaWiki writer: use HTML spans for anchors when header has id (#7697). We need to generate a span when the header’s ID doesn’t match the one MediaWiki would generate automatically. Note that MediaWiki’s generation scheme is different from pandoc’s (it uses uppercase letters, and _ instead of -, for example). This means that in going from markdown to mediawiki, we’ll now get spans before almost every heading, unless explicit identifiers are used that correspond to the ones MediaWiki auto-generates. This is uglier output but it’s necessary for internal links to work properly.

  • Markdown writer: don’t create autolinks when this loses information (#7692). Previously we sometimes lost attributes when rendering links as autolinks.

  • Text.Pandoc.Readers.Metadata: allow multiple YAML documents when parsing YAML for yamlBsToRefs. Some people use --- as the end delimiter in YAML bibliography files, which causes the yaml library to emit an error unless we explicitly allow multiple YAML documents (and just consider the first).

  • JATS writer:

    • Ensure figures are wrapped with <p> in list items (Albert Krewinkel). This prevents the generation of invalid output.
    • Add URL to element citation entries (Albert Krewinkel). The URL of a reference, if present, is added in tag <uri> to element-citation entries.

  • HTML writer: Don’t create invalid data- attribute for empty attribute key (#7546).

  • LaTeX writer:

    • Babel mappings: use ancientgreek for grc.
    • With -t latex-smart, don’t generate \ldots from ellipsis (#7674). Instead just use unicode ellipsis.

  • JATS template: fix equal-contrib attribute (Albert Krewinkel). The standard requires the value to be either yes or no, but is was set to true for authors who contributed equally.

  • reveal.js template: Add disableLayout variable (Christophe Dervieux).

  • Text.Pandoc.Error: sort errors in handleError by exit code (Albert Krewinkel).

  • Text.Pandoc.Writers.Shared: Improve toLegacyTable (#7683, Christian Despres).

  • Lua subsystem:

    • Include lpeg module (#7649, Albert Krewinkel). Compiles the lpeg library (Parsing Expression Grammars For Lua) into the program. Package maintainers may choose to rely on package dependencies to make lpeg available, in which case they can compile the with the constraint lpeg +rely-on-shared-lpeg-library. lpeg and re are always made available in global variables, without the need for a require.

    • Set lpeg and re as globals; allow shared lib access via require. The lpeg and re modules are loaded into globals of the respective name, but they are not necessarily registered as loaded packages. This ensures that

      • the built-in library versions are preferred when setting the globals,
      • a shared library is used if pandoc has been compiled without lpeg, and
      • the require mechanism can be used to load the shared library if available, falling back to the internal version if possible and necessary.

    • Fix argument order in constructor pandoc.Cite (Albert Krewinkel). This restores the old behavior; argument order had been switched accidentally in pandoc 2.15.

    • Add Pushable instance for ReaderOptions (Albert Krewinkel).

    • Allow to pass custom reader options to pandoc.read as an optional third argument (#7656, Albert Krewinkel). The object can either be a table or a ReaderOptions value like PANDOC_READER_OPTIONS. Creating new ReaderOptions objects is possible through the new constructor pandoc.ReaderOptions.

    • Display Pandoc values using their native Haskell representation (Albert Krewinkel).

    • Require latest hslua (2.0.1) (#7661, #7657, Albert Krewinkel). This fixes issues with

      • misleading error messages when a required function parameter is omitted;
      • absent properties still being listed in the output of pairs; and
      • alias accessing leading to errors instead of returning nil, e.g. with (pandoc.Str '').identifier.

    • Add missing space in “package not found” message (#7658, Albert Krewinkel).

  • Update build files (#7696, Fabián Heredia Montiel). Drop old windows 32-bit constraints. Update cabal tested-with field to correspond to ci.yml matrix

  • Remove unneeded package dependencies from benchmark target.

  • Require ghc >= 8.6, base >= 4.12. This allows us to get rid of the old custom prelude and some crufty cpp. But the primary reason for this is that conduit has bumped its base lower bound to 4.12, making it impossible for us to support lower base versions.

  • Require Cabal 2.4. Use wildcards to ensure that all pptx tests are included (#7677).

  • Update bash_completion.tpl (S.P.H.).

  • Add data/creole.lua as sample custom reader.

  • Add doc/custom-readers.md and doc/custom-writers.md.

  • doc/lua-filters.md: add section on global modules, including lpeg (Albert Krewinkel).

  • MANUAL.txt: update table of exit codes and corresponding errors (Albert Krewinkel).

  • Use latest texmath.
