CTAN update: expltools
by CTAN Announcements 09 Apr '26

09 Apr '26

Vít Starý Novotný submitted an update to the expltools package. Version: 2026-04-07 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: -------------------------------------------------------------------------------- ## expltools 2026-04-07 ### explcheck v0.19.1 #### Fixes This version of explcheck has fixed the following problems: - Fix malformed context for issue E505 (Calling an undefined function). (reported by @muzimuzhi in #191, fixed in #193) - Do not capture a newline after expl3-like material. (#193) This excludes the newline from the context messages and byte ranges for issues like E102 (Expl3 material in non-expl3 parts). - Only put argument specifiers in the context of issue E201 (Unknown argument specifiers), not the whole control sequence name. (#193) This makes the context of issue E201 consistent with issue E427 (Comparison conditional without signature `:nnTF`). - Fix the context of issue W200 ("Do not use" argument specifiers) missing characters when the name of the control sequence ends with double-superscript characters, like `\tex_let:^^44`. (#193) - Report resolved control sequence names (like `\tex_let:D`) instead of the raw input text (like `\tex_let:^^44`) for issues W200 and W202 (Deprecated control sequences). (#193) - Fix an incorrect assertion in code that reports issues E500 (Multiply defined function) and W501 (Multiply defined function variant). (reported by @muzimuzhi in #192, fixed in #194) - Do not consider a definition being reached by itself a redefinition. (reported by @muzimuzhi in #192, fixed in #194) This prevents false positive detections of the issues E500 and W501. - Do not report issue E505 (Calling an undefined function) when calling empty functions. (reported by @muzimuzhi in #192, fixed in #194) - Weaken the confidence of incoming reaching definitions when the in-degree is greater than one. (reported by @muzimuzhi in #192, fixed in #194) - Do not report issues for uninteresting macro-statements that are skipped during flow analysis and therefore have incomplete or unreliable information recorded. (#194) - Only require definite reaching definitions for issues E500 and W501, not issues E504 (Function variant for an undefined function), E506 (Indirect function definition from an undefined function), and W507 (Setting a function before definition). (#194) #### Continuous integration This version of explcheck has made the following changes to our continuous integration: - Check issue context in tests. (reported by @muzimuzhi in #191, added in #193) -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/support/expltools More information is at https://ctan.org/pkg/expltools -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: context-notes-zh-cn

Yanrui Li submitted an update to the context-notes-zh-cn package. Version number: 2026-04-08 License type: fdl Summary description: A ConTeXt LMTX introduction for Chinese users Announcement text: ---------------------------------------------------------------------- The following is mainly a correction of several writing errors in the documentation, along with refinements to some previously hasty wording. The main content remains largely unchanged. The copyright of the documentation has been slightly modified, with some simple clauses added to meet the Debian community's rigorous licensing requirements for the TeXLive package. A new chapter, chapter 17 — a brief introductory guide to TEX programming — has been added. Originally, I planned to use it to demonstrate some applications of TEX programming in typesetting, but after some attempts, I decided to keep it as simple as possible, merely aiming to dispel fear of TEX programming. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/info/context-notes-zh-cn More information is at https://www.ctan.org/pkg/context-notes-zh-cn ------------------------------------------------------------------------ Thanks for the upload.

Aaron Molt submitted the sneaker package. Version: 1.0 2026-04-03 License: lppl1.3c Summary description: Configurable Sneakers with TikZ Announcement text: ---------------------------------------------------------------------- The 'sneaker' package provides a highly configurable TikZ pic to draw stylised sneakers in an isometric-like perspective. The shoe can be extensively customised via a simple key–value interface. Features include adjustable colours for various components, shoelaces with a bow, velcro straps, metal eyelets, and decorative patterns such as a lightning bolt or a star. For more detailed illustrations, the package also offers options for dashed stitching lines and even rolling wheels to transform the sneaker into an inline skate. What started as a small visual gimmick for the slides of my Bachelor’s thesis, a sneaker as a feature model to illustrate variability and configuration, gradually grew into something more elaborate that I decided to share with the community. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/sneaker The package’s files themselves can be inspected at https://mirrors.ctan.org/graphics/pgf/contrib/sneaker/ ---------------------------------------------------------------------- Thanks for the upload.
