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.
