CTAN update: expltools

Vít Starý Novotný submitted an update to the expltools package. Version: 2026-04-13 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: ---------------------------------------------------------------------- ## expltools 2026-04-13 ### explcheck v0.19.2 #### Fixes This version of explcheck has fixed the following problems: - Recognize `\prop_new_linked:N` as a variable declaration statement and `\prop_const_from_keyval:Nn`, `\prop_const_linked_from_keyval:Nn`, `\prop_set_from_keyval:Nn`, and `\prop_gset_from_keyval:Nn` as constant and variable definition statements. (reported by @muzimuzhi in #196, fixed in #198) More generally, this change also adds support for constant definitions in the form `\⟨type⟩_const_from_⟨base_type⟩:*`. This improves [code coverage][] by 37,759 expl3 tokens (~0.004% of all expl3 tokens) on TeX Live 2026. - Correctly differentiate between direct and indirect variable and constant definitions in the form `\⟨type⟩_(set|gset|const)_from_⟨base_type⟩:*`. (#198) - Only report issues E504 (Function variant for an undefined function), E506 (Indirect function definition from an undefined function), and W507 (Setting a function before definition) for top-level reachable segments. (reported by @muzimuzhi in #195, fixed in #198) - Do not report issue E505 (Calling an undefined function) for indirect definitions that resolve to well-known control sequence names. (reported by @muzimuzhi in #197, fixed in #198) [code coverage]: https://witiko.github.io/Expl3-Linter-11/#code-coverage #### Continuous integration This version of explcheck has made the following changes to our continuous integration: - Update the `zauguin/install-texlive` action to v4.3. (484989a) - Retry `tlmgr install` and `update`. (#198) ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/expltools The package’s files themselves can be inspected at https://mirrors.ctan.org/support/expltools/ ---------------------------------------------------------------------- Thanks for the upload.

CTAN update: The Comprehensive LaTeX Symbol List
by CTAN Announcements 14 Apr '26

14 Apr '26

Scott Pakin submitted an update to the The Comprehensive LaTeX Symbol List package. Version: 16.0 License: lppl1.3c Summary description: Symbols accessible from LaTeX Announcement text: -------------------------------------------------------------------------------- The Comprehensive LaTeX Symbol List is a document that organizes over 25000 symbols accessible from LaTeX by topic and package. The aim is to make it easy to find symbols and learn how to incorporate them into a LaTeX document. An index further helps locate symbols of interest. Much has changed since the last release of the Comprehensive LaTeX Symbol List over two years ago. Most notably, the list presents thousands of new symbols from a handful of additional packages. Smaller improvements include refactoring a few tables into more meaningful pieces, updating a few tables to cover recently added or renamed symbols, moving brand icons and logos into their own chapter, and making numerous small improvements to the index to better categorize the symbols appearing in the document. The accompanying SYMLIST text file now uses two columns to present a mapping from user-visible control sequences to the document's internal representation. While not visible to the reader of the Comprehensive LaTeX Symbol List, compilation has been sped up immensely by leveraging the Ninja build system. The document builds with LuaLaTeX whereas previous versions required pdfLaTeX. In fact, the companion Raw Font Tables document now requires LuaLaTeX, which it exploits to show font tables for OpenType and TrueType fonts that define more than 256 characters. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/info/symbols/comprehensive More information is at https://ctan.org/pkg/comprehensive -------------------------------------------------------------------------------- Thanks for the upload.
