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.
