CTAN update: pyjupyter
by CTAN Announcements 18 Mar '26

18 Mar '26

Bara Ouyèté Bright submitted an update to the pyjupyter package. Version: 1.2.0 2026-03-15 License: lppl1.3c Summary description: Lightweight environment for typesetting Python code Announcement text: -------------------------------------------------------------------------------- I am pleased to announce version 1.2.0 of the pyjupyter package. This new release introduces support for including external Python files directly in LaTeX documents through the `\inputpythonfile` command. This command allows users to embed Python scripts inside Jupyter-style code boxes while preserving syntax highlighting, optional line numbering, and the visual formatting provided by the package. It is also possible to display only selected portions of a file by specifying a range of lines, which is particularly useful when presenting excerpts of longer programs. With this addition, pyjupyter becomes more convenient for teaching materials, programming assignments, and technical documentation where code stored in external files needs to be displayed clearly within a LaTeX document. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/pyjupyter More information is at https://ctan.org/pkg/pyjupyter -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: expltools
by CTAN Announcements 14 Mar '26

14 Mar '26

Vít Starý Novotný submitted an update to the expltools package. Version: 2026-03-13 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: ---------------------------------------------------------------------- ## expltools 2026-03-13 ### explcheck v0.18.2 #### Fixes This version of explcheck has fixed the following problems: - Support `c`-type arguments in variable and constants declarations, definitions, and uses. (#187) This improved [code coverage][] from ca 21% to 25% of all expl3 tokens on TeX Live 2024. - Do a better job detecting arguments in unrecognized replacement texts when extracting control sequence name patterns from `c`-type arguments in function calls. (#187) - In semantic analysis, consider the base variables in indirect variable definitions to be used, similarly to how base functions in indirect function definitions are considered used. (#187) This has removed a dozen false positive detections of issue W415 (Unused variable or constant) on TeX Live 2024. - Include `\q_no_value` among well-known expl3 control sequence names. (#187) - Have the issue E417 (Setting a variable as a constant) mask the issue E421 (Globally setting a local variable). (#187) This has removed a couple questionable detections of the issue E421 on TeX Live 2024. - Only consider potentially used function (variant) (un)definitions in the flow analysis. (suggested by @lostenderman in #156, fixed in #187) This change improves processing time by about 3% for an average package file in TeX Live 2024, and by up to 91% (or 11×) for large files such as `expl3-code.tex` when flow analysis is enabled despite incomplete code understanding. It also reduces the memory footprint of flow analysis by up to 4× for those files. After this change, the default value of the Lua option `max_reaching_definition_inner_loops` has been reduced from 650,000 to just 350,000 inner-loop iterations. Overall, the changes in the past two releases have reduced the processing time for large files such as `expl3-code.tex` from months to a little over an hour (up to 800×) when flow analysis is enabled despite incomplete code understanding, and have reduced the memory footprint of flow analysis by up to 12× for those files.
