CTAN update: expltools
by CTAN Announcements via ctan-ann 31 May '26

31 May '26

Vít Starý Novotný submitted an update to the expltools package. Version number: 2026-05-29 License type: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: ---------------------------------------------------------------------- ## expltools 2026-05-29 ### explcheck v0.22.0 #### New features This version of explcheck has implemented the following new features: - Add more support for flow analysis. (#218) This adds support for the following issues from the document titled [_Warnings and errors for the expl3 analysis tool_][warnings-and-errors]: 1. W517 (Unused variable or constant) - In the semantic analysis, add a call type for standalone variable or constant control sequences. (#213, #215) Previously, standalone variable or constant control sequences were considered other unrecognized tokens. This has improved [code coverage][] by 33,294 expl3 tokens (~0.4% of all expl3 tokens) on TeX Live 2025. - Perform semantic analysis on boolean expression segments. (#213, #215) - Detect boolean expression segments in calls to control sequences like `\bool_if:nTF`. (#215, #217) - Emit both `VARIABLE_DECLARATION` and `VARIABLE_DEFINITION` statements for constant definitions like `\tl_const:Nn`. (#218) Previously, only a `VARIABLE_DEFINITION` statement would have been produced, requiring special-casing for issues like W415 (Unused variable or constant), W416 (Setting an undeclared variable), and W419 (Using an undeclared variable or constant). - In flow analysis, draw `VARIABLE_USE` and `VARIABLE_USE_RETURN` edges. (#218) - Include the number of reaching definition loops in verbose command-line output. (#218) #### Fixes This version of explcheck has fixed the following problems: - Do not report issue W415 (Unused variable or constant) for defined box variables. (reported by @dcpurton in #214, fixed in #216) Defining box variables can have useful side effects even if the variable isn't used elsewhere. - In the semantic analysis, consider `\⟨type⟩_log:*` a variable use. (#217) - Reduce false positive detections of issues E408 (Calling an undefined function), E411 (Indirect function definition from an undefined function), and W416 (Setting an undeclared variable). (#218) This was achieved by using pattern-based matching for only partially understood variable declarations and function definitions. #### Warnings and errors This version of explcheck has made the following changes to the document titled [_Warnings and errors for the expl3 analysis tool_][warnings-and-errors]: - Remove planned issue W511 (Defined an expandable function as protected), since it doesn't actually constitute an issue: there are good reasons to protect a function from expansion, even if it is otherwise expandable. (#213) #### Housekeeping This version of explcheck has completed the following housekeeping tasks: - Reduce repetition in the function `analyze_group_wide_statements()` from `explcheck-semantic-analysis.lua` by introducing two new mechanisms: maybe-trackers and statement category lists and indices. (#217) #### Continuous integration This version of explcheck has made the following changes to our continuous integration (CI): - In the CI, force flow analysis for TeX Live 2025 rather than the latest TeX Live, so that we can compare the diff against our 2025 baselines. (ea03ec0) - In the CI, check that the `lua-toml` submodule is up-to-date even if checking the `latex3` submodule failed. (340f6bc) #### Dependencies This version of explcheck has made the following changes to third-party Git submodules and other dependencies: - Update the `latex3` submodule from 2026-04-28-dev to 2026-05-15-dev. (85b126a) [code coverage]: https://witiko.github.io/Expl3-Linter-11/#code-coverage [warnings-and-errors]: https://github.com/witiko/expltools/releases/download/latest/warnings-and-e… ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/support/expltools More information is at https://www.ctan.org/pkg/expltools ------------------------------------------------------------------------ Thanks for the upload.

Werner Fink submitted an update to the boldtensors package. Version: 2026-05-21 License: gpl2 Summary description: Bold latin and greek characters through simple prefix characters Announcement text: ---------------------------------------------------------------------- Description The boldtensors package provides a highly efficient shorthand for typesetting Latin and Greek characters in bold and blackboard-bold layouts. It is specifically designed for the requirements of Theoretical Physics and General Relativity, where a clear visual distinction between geometric tensor objects and their components or scalars is essential. The package uses active characters (~ and ") to keep the source code clean and readable: - `$~T$` produces a bold tensor T. - `$"R$` produces a blackboard-bold symbol ℝ. Key Features: • Engine Independent: Fully compatible with both classical pdfLaTeX (using NFSS) and modern LuaLaTeX (using unicode-math and OpenType fonts). • ISO Compliance: Includes the bt-isodiff sub-package for upright differential operators according to ISO 80000-2. • Accurate Metrics: Correct placement of subscripts, superscripts, and accents (like \hat{~T}) by using native math characters instead of boxes. • Micro-Typography: Preserves perfect kerning and font-specific metrics. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/boldtensors The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/boldtensors/ ------------------------------------------------------------------------ Thanks for the upload.

No more deriving N by hand from Tmax/dt. * \mstep{<Name>}{<i>} now raises a numodel error when <i> is outside the recorded range, instead of silently expanding to nothing. * \textmodel: alias keys (alias, aliasleft, aliasright) now work with amsmath dots macros (\cdots, \ldots, \dotsb, ...). Fixes a regression introduced in v0.4.0 by the tabularray migration. * \graphicmodel auto-layout no longer leaves an empty row between the stocks row and the constants row when the model has no auxiliary variables. Build / packaging changes ------------------------- * The user manual moved out of the .dtx into stand-alone numodel-manual.tex / numodel-plot-manual.tex. The .dtx is now pure docstrip source. Manuals use Arial + Lete Sans Math + Fira Mono and a tcolorbox+listings example environment so each example is shown verbatim and executed from a single source. * The examples/ directory is no longer shipped to CTAN.

Co-Authored-By: Claude Sonnet 4.6 <noreply(a)anthropic.com> ## pkgcheck 2026-05-24 (4.0.1) ### Fixed Fix three parser bugs in nom_parsing.rs - keep may_generate=true when a macro is redefined with a non-generating body (sticky flag). Fixes ctable/isodoc where \ifx...\else...\fi guards a generating and a no-op \def of \Extract. - introduce skip_control_symbol so the fallback branch advances past \X (backslash + one character) rather than just the backslash.

It can draw: * a single subshell (`\suborbital`), * a row of subshells (`\electronconfig`), * a valence configuration with a noble-gas core (`\atomconfig`), * an empty transition-series template (`\transitionseries`). Every diagram can be scaled and placed inline in running text.
