CTAN update: dirtreex
by CTAN Announcements 29 May '26

29 May '26

CloudCauldron submitted an update to the dirtreex package. Version: 1.1 2026-05-27 License: lppl1.3c Summary description: Directory tree rendering for LaTeX with TikZ Announcement text: ---------------------------------------------------------------------- This release brings native support for verbatim paths, new archive entry types, and removes the legacy 'environ' dependency in favor of LaTeX's native environment hooks. New Features: - \archive & \verbarchive: New container-style entries that render without the trailing slash, designed for archive files (e.g., .zip, .tar.gz). The \verb... variant utilizes xparse's verbatim argument, allowing paths with special characters to survive without escaping; - \verbdir & \verbfile: Verbatim siblings of \dir and \file, safely handling path names containing _, $, &, #, ^, ~, %, \, {, }, or |; - Line style per-entry override: A new override key accepting any TikZ line-style token; - Public \DirtreexGetField{idx}{slot}: Allows user-supplied \renewcommand\DirtreexFormatName hooks to read stored entry fields safely without \makeatletter. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/dirtreex The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/dirtreex/ ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: boldtensors
by CTAN Announcements 28 May '26

28 May '26

Werner Fink submitted an update to the boldtensors package. Version: 2026-05-21 License: gpl2 Summary description: Bold latin and greek characters through simple prefix characters Announcement text: ---------------------------------------------------------------------- Description The boldtensors package provides a highly efficient shorthand for typesetting Latin and Greek characters in bold and blackboard-bold layouts. It is specifically designed for the requirements of Theoretical Physics and General Relativity, where a clear visual distinction between geometric tensor objects and their components or scalars is essential. The package uses active characters (~ and ") to keep the source code clean and readable: - `$~T$` produces a bold tensor T. - `$"R$` produces a blackboard-bold symbol ℝ. Key Features: • Engine Independent: Fully compatible with both classical pdfLaTeX (using NFSS) and modern LuaLaTeX (using unicode-math and OpenType fonts). • ISO Compliance: Includes the bt-isodiff sub-package for upright differential operators according to ISO 80000-2. • Accurate Metrics: Correct placement of subscripts, superscripts, and accents (like \hat{~T}) by using native math characters instead of boxes. • Micro-Typography: Preserves perfect kerning and font-specific metrics. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/boldtensors The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/boldtensors/ ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: maze
by CTAN Announcements 27 May '26

27 May '26

Sicheng Du submitted an update to the maze package. Version: 1.3 2026-05-25 License: lppl1.3c Summary description: Announcement text: -------------------------------------------------------------------------------- Changes in this version 1. Added input validation for the `size` argument: it must be an integer in the range 2--99; the package now raises an error for out-of-range values. 2. Added a storage feature: `\mazesave{name}{size}[seed]` saves the rendered maze in a named box register so that the exact same maze can be reproduced later. Stored mazes also keep a solved overlay, and `\mazeuse[view]{name}` can typeset that overlay on demand. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/maze More information is at https://ctan.org/pkg/maze -------------------------------------------------------------------------------- Thanks for the upload.
