by CTAN Announcements 05 Oct '25

05 Oct '25

Alain Matthes submitted an update to the tkz-elements package. Version number: 4.30c 2025-10-04 License type: lppl1.3c Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide Announcement text: ---------------------------------------------------------------------- [2025/10/04 version 4.30c] Added - circle: - in_disk same as in_out_disk - on_circle same as in_out - in_disk_strict - out_disk_strict - line - side_line This method assigns a value of -1, 0, or 1 to a given point depending on its position in the plane relative to the line. - on_line = in_out_line - on_segment = in_out_segment ### Changed - circle - common_tangent Complete rewriting of the procedure, which now takes into account the position of circles and, above all, adds an option to choose between external tangents and internal tangents when they exist. - c_cc_p Complete rewriting of the procedure. You can use an “external” or “internal” option to determine whether solution circles exist. The method takes into account the relative position of the circles. - line - c_ll_p(L, p) now has a line and a point as its argument. Docs - Correction of typography. - Adjusting documentation for new methods. - Rewriting of numerous method presentations. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/tkz/tkz-elements More information is at https://www.ctan.org/pkg/tkz-elements ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: expltools
by CTAN Announcements 05 Oct '25

05 Oct '25

Vít Starý Novotný submitted an update to the expltools package. Version: 2025-10-04 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: -------------------------------------------------------------------------------- ## expltools 2025-10-04 ### explcheck v0.14.0 #### Fixes This version of explcheck has fixed the following bugs: - Do not produce a Lua error when trying to generate all compatible specifiers for base specifiers `T`, `F`, `p`, `w`, and `D`. (reported by @muzimuzhi in #137, fixed in #138) - Fix the description of issue S413, which was previously "Malformed variable or constant" rather than "Malformed variable or constant _name_". (reported in #137 and #139, fixed in #140) - Reduce the range of semantic analysis issues to the smallest possible code region. (reported by @muzimuzhi in #137 and #139, fixed in #140) This is to reduce the chance of `% noqa` comments within long statements inadvertently silencing issues related to other parts of the statement. Specifically, the ranges of the following issues were narrowed from entire statements to particular parts of those statements: 1. **W401 (Unused private function) and E404 (Protected predicate function):** From the beginning of the function definition to the beginning of the function replacement text (exclusive), if any, or the whole function definition otherwise. 2. **T403 (Function variant of incompatible type) and W410 (Function variant of deprecated type):** The argument with the list of variant specifiers. 3. **E405 (Function variant for an undefined function):** The argument with the function name. 4. **E408 (Calling an undefined function):** The undefined function name. 5. **S412 (Malformed function name), S413 (Malformed variable or constant name), and S414 (Malformed quark or scan mark name):** The argument with the malformed name. 6. **W415 (Unused variable or constant), W416 (Setting an undeclared variable), E417 (Setting a variable as a constant), E418 (Setting a constant), W419 (Using an undeclared variable or constant), E420 (Locally setting a global variable), and E421 (Globally setting a local variable):** The argument with the variable or constant name. 7. **T422 (Using a variable of an incompatible type):** From the beginning of the variable/constant declaration/definition/use to the beginning of any arguments following the variable/constant names (exclusive). 8. **W423 (Unused message):** From the beginning of the message definition to the beginning of the message text (exclusive). 9. **E424 (Using an undefined message):** From the beginning of the message use to the first text argument (exclusive), if any, or the whole message use otherwise. 10. **E425 (Incorrect parameter in message text):** The incorrect parameter token. 11. **E427 (Comparison conditional without signature `:nnTF`):** The argument with the comparison conditional name. #### 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]: - Fix the documentation of issue S413 (Malformed variable or constant name). (reported by @muzimuzhi in #137 and #139, fixed in #140) The module name is mandatory in the variable and constant name, as documented in Section 3.2 (Formal naming syntax) of the document titled [_The `expl3` package and LaTeX3 programming_][expl3]. - Change the description of issue E425 from "Incorrect parameters in message text" to "Incorrect parameter in message text". (#140) [expl3]: https://mirrors.ctan.org/macros/latex/required/l3kernel/expl3.pdf [warnings-and-errors]: https://github.com/witiko/expltools/releases/download/latest/warnings-and-e… #### Continuous integration This version of explcheck has made the following changes to our continuous integration: - Generate the file `explcheck-latex3.lua` from the files `l3obsolete.txt` and `l3prefixes.csv` in the package `l3kernel-dev` rather than `l3kernel`.
