unified-latex Changelog

Unreleased

v1.8.5

  • PreTeXt conversion improvements:
    • Support the exam document class (questions, parts, choices, solutions, etc.).
    • Support top-level divisions (article/book/slideshow) and better handling of specialized divisions.
    • Support plus-prefixed inclusion macros.
    • Support Beamer and tikzpicture conversion.
    • Support slide and frame environments as synonyms.
    • Support math environments (align, equation, gather, multline, alignat, etc.).
    • Basic bibliography support (thebibliography/\bibitem), with better BibTeX/CSL-based formatting.
    • Add <bibinfo> support and improve detection of macros/environments that don't apply to PreTeXt.
    • Handle comments and unknown tags instead of erroring.
    • Handle vertical space (\vspace, \bigskip, etc.) and starred environments.
    • Add capitalization variants for some macros.
    • Escape slashes when generating xml:ids.
    • Fix issue with synonyms of environments not getting titles.
  • Fix TypeScript build configuration issues.
  • Add many additional tests for PreTeXt conversion.

v1.8.4

  • PreTeXt conversion improvements:
    • Support most environments and macros for PreTeXt conversion.
    • Labels handled correctly in PreTeXt conversion.
    • LaTeX quotes converted to <q> in PreTeXt conversion.
  • Fix issue where \begin{lstlisting} environment could not take optional arguments.

v1.8.3

  • Support \ref in PreTeXt conversion
  • Better use of UnifiedJS to parse but not print LaTeX
  • Support for \verb, \textsuperscript, \textsubscript, \sout, and \" i in HTML conversion

v1.8.2

  • Upgraded dependencies

v1.8.1

  • Changed Peggy to implement a caching parser to prevent large slowdown on some files.

v1.8.0

  • Added initial PreTeXt conversion support
  • Upgraded deps
  • Added amsart macros
  • Consume the whitespace after special character macros when expanding ligatures. For example \o y produces øy instead of ø y
  • Fix signatures of \hyphenation

v1.7.1

  • Types fix for @unified-latex/unified-latex-types
  • Fixed AST when expanding \sysdelim macros for rendering \systeme{} macros with KaTeX

v1.7.0

  • Switch build system to vite. Should result in smaller bundles.
  • Save default arguments when parsing if the macro signature specifies them e.g. {signature: "O{foo}"}. The defaults are substituted in when expanding the macros with the optional arguments omitted.
  • Preserve position information when comments are modified. (Sometimes, during a parse, but never during a parseMinimal, comments are modified to remove leading whitespace. Previously, modified comments would have their position information deleted. Position information is now preserved.)

v1.6.1

  • Pass VisitInfo as an additional argument ot macroReplacers and environmentReplacers in unifiedLatexToHast.
  • Allow skipping of HTML validation in unifiedLatexToHast.
  • The minted environment parses its contents as a verbatim.

v1.6.0

  • Embellishment tokens are now supported in macro signatures. E.g., a xxx: {signature: "e{^_}"} will allow \xxx_{foo}^{bar} and \xxx^{foo}_{bar} to parse correctly.
  • Stop tokens can now be regular string characters. For example xxx: {signature: "ua"} will allow \xxx YYYaBBB to consume YYY leaving BBB unconsumed.
  • Break after \\ macro when pretty printing (Issue #59)
  • [DEVELOPMENT] Added tsconfig.json files to each test/ folder for more granular control of the typescript settings.

v1.5.0

  • HTML conversion: vspace and hspace now give the amount in a data-amount attribute.
  • HTML conversion: unknown macros now have their arguments wrapped in spans instead of appearing as formatted LaTeX code.
  • Add basic Markdown conversion support.

v1.4.2

  • Avoid slowdown when paring incomplete environments (e.g. \newcommand{\x}{\begin{x}}). This is accomplished by enabling caching in PEGjs.
  • Added " ligature and \paragraph and \subparagraph to HTML conversion.

v1.4.1

  • Many more ligatures added to the HTML converter.
  • Fixed issue #40 where the optional argument to \\ was being parsed even if preceded by a space. (E.g., \\[10pt] and \\ [10pt]) were parsed the same. Not allowing the space should more closely match expected behavior.
  • Bump Prettier to v2.8.8

v1.4.0

  • Better CJS support (now unified is compiled in rather than left as an external dependency. This is needed because unified is ESM-only).
  • minted and listings environments now accept optional arguments and parse their contents verbatim. This makes them much more efficient.

v1.3.0

  • Initial support for parsing and pretty-printing of tikz environments.
  • Added support for xparse u-type arguments.
  • Can now pass an argumentParser attribute for custom argument parsing (instead of relying on an xparse signature)
