Scot Parker submitted the jiffy package. Version: 0.2a License: lppl1.3c Summary description: TikZ-based page-geometry diagnostic tool Announcement text: -------------------------------------------------------------------------------- I am pleased to announce the initial release of jiffy, a modern, TikZ-based page-layout diagnostic tool for LaTeX. The jiffy package provides a highly robust, properly scaled map of a document's page geometry, serving as a mathematically accurate alternative to the classic layout package. Key features include: Dynamic staggering of metric labels to prevent visual collisions. Active, automated diagnostics that warn you if text blocks or headers extend off the page. Native multi-language support (English, Vietnamese, Spanish, German, French, and Dutch). I hope the LaTeX community finds it useful! -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/graphics/pgf/contrib/jiffy More information is at https://ctan.org/pkg/jiffy -------------------------------------------------------------------------------- Thanks for the upload.

New on CTAN: INSPIRE-HEP
by CTAN Announcements 30 Aug '26

30 Aug '26

Lawrence Lee submitted the INSPIRE-HEP package. Version: 0.2 License: lppl1.3c Summary description: An INSPIREHEP × LaTeX interface for automatic reference management Announcement text: -------------------------------------------------------------------------------- inspirehep-latex fills in references from InspireHEP. Hand it an Inspire ID or a BibTeX key, and it writes the whole entry: authors or collaboration, title, journal, arXiv number, and a citation count. Author-level figures and citations-per-year plots come from the same place. It is aimed at CVs and publication lists, where references go stale and formatting drifts. \inspirecite is \cite by Inspire ID to easily build bibliographies automatically without manual .bib file creation. LPPL 1.3c, on CTAN and at github.com/lawrenceleejr/inspirehep-latex. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/inspirehep More information is at https://ctan.org/pkg/inspirehep -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: asymptote
by CTAN Announcements 30 Aug '26

30 Aug '26

John Bowman submitted an update to the asymptote package. Version: 3.14 License: lgpl3 Summary description: 2D and 3D TeX-Aware Vector Graphics Language Announcement text: -------------------------------------------------------------------------------- String bracket indexing via operator[] was added. A high-performance sphere approximation based on Bezier triangles was implemented for the native renderer and ported to AsyGL. A bitmap preview is generated for V3D PDF output so it displays correctly in non-interactive viewers. IBL environment names are now output in the V3D header and IBL fixes were made for Vulkan and AsyGL. A stack overflow with -render=0 was fixed. The Vulkan export now uses tiling with a dynamic viewport and scissor. Rendering issues with pixel() were fixed. Triangle group rendering and a vertex shader bug in the no-lighting path were fixed in the AsyGL library. Threaded renderer crashes on empty scenes and a division by zero were fixed. Surfaces are no longer interpolated as periodic unless they really repeat, and the parametric surface() constructor in graph3 enforces exact endpoint periodicity for periodic splinetypes. A bug in the monotonic splinetype was fixed. The asyinclude function in the slide module now restores currentlight, currentpen, and currentprojection. Documentation and build issues were addressed. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/graphics/asymptote More information is at https://ctan.org/pkg/asymptote -------------------------------------------------------------------------------- Thanks for the upload.
