New on CTAN: luamathaccents
by CTAN Announcements 28 Jul '26

Joris Pinkse submitted the luamathaccents package. Version: 1.0 2026-07-26 License: lppl1.3c Summary description: Use Unicode combining accents in math input with LuaLaTeX Announcement text: ------------------------------------------------------------------------ luamathaccents lets you type accented mathematical symbols directly in your source file using Unicode combining characters. With the package loaded, the two-character sequence “x” + U+0302 (combining circumflex accent) – which your editor displays as an accented letter – is rewritten on input to “\hat x”, and likewise for two dozen other combining characters (grave, acute, tilde, macron, breve, dot, diaeresis, caron, vector arrow, harpoons, and more). The package uses LuaTeX’s process_input_buffer callback and therefore requires LuaLaTeX. This is the first release. ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/luamathaccents The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/luatex/latex/luamathaccents/ ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: xecjk
by CTAN Announcements 26 Jul '26

26 Jul '26

Liam Huang submitted an update to the xecjk package. Version: 3.10.4 License: lppl1.3c Summary description: Typeset CJK in XeLaTeX Announcement text: ------------------------------------------------------------------------ This release introduces a unified command-boundary capture/register framework that replaces numerous ad-hoc mechanisms for handling inter-character spacing around boxes, color changes, hyperlinks, and third-party commands. It also fixes several boundary and glue-handling bugs. NEW FEATURES - New command-boundary capture/register framework that determines the visible head/tail character class of boxes, opaque node streams, and commands with no visible output, and restores inter-character boundaries accordingly (#992). - New experimental `experiment/boundary-register` interface allowing expert users to register custom commands into the unified command-boundary framework (#1010). - New dedicated inline-math boundary class that separately handles end-of-formula spacing and post-formula source spaces in argument contexts, enabling registered commands to restore left/right boundaries with correct direct-formula source-space semantics (#1002). - New `\@@_glue_check_expire_stale:` routine: when the top-level recovery chain finds an empty node list, it clears stale pending state, preventing `\g_@@_glue_check_pending_bool` from surviving across `\hbox`/`\setbox` boundaries (#996). - `siunitx` compatibility: `\unit`, `\qty`, `\num` and v2 legacy names `\si`, `\SI` are registered as fixed Default head/tail stream captures, fixing space loss at unit-command boundaries in CJK context (#1000). BUG FIXES - Fixed range parsing of default endpoints in `\@@_check_num_range:nnNN`. - Boundary-to-CJK source-space check now uses the same `\@@_skip_if_interword:N` test as the Default direction; explicit glue whose natural width differs from the current inter-word space is no longer replaced by `\CJKglue` (#996). - box/wrapped-box capture now rebuilds boundaries as Default head/tail when a box has emitted visible content (non-zero width, non-zero height or depth, with a terminal char/rule/math/kern node) but no character class was observed. Math and `\vrule` etc. that do not trigger interchar transitions are no longer misidentified as "no visible output" (#998). - Default marker replay now synchronises `\spacefactor` with the outer list; post-transparent processing also relocates the marker together with its candidate glue, fixing right-boundary spacing when `xCJKecglue` is enabled and a trailing uppercase letter or `\null` inside a box obscures the boundary suffix (#1003). - Invisible nodes separating a real space from a marker in a normal stream now cause the marker to expire (direct-formula semantics) and preserve the original ordering of intermediate glue and nodes (#1002). - Fixed nested `ulem`/xeCJKfntef underline commands: only the outermost invocation now starts a stream capture, preventing per-nesting state leakage on the capture stack (#992). DOCUMENTATION - Clarified that `xCJKecglue` also controls source spaces adjacent to inline math (#1002). - Documented in the user manual that TeX cannot distinguish source spaces from certain explicit glue, and provided a zero-width `\kern` workaround (#992). - Added Boundary→CJK direction note: certain explicit glue may also be replaced by `CJKglue` (#996). INTERNAL CHANGES - Allowed the Boundary-to-Default recovery path to tentatively remove trailing source inter-word glue that has no infinite-order stretch but does have shrink; if a CJK marker is found beneath, it is replaced by `\CJKecglue`, completing symmetric command-boundary handling with the Default-to-CJK direction (#992). - Command-boundary framework now manages `xeCJKfntef`, box commands, and color commands; removed the legacy fallback that guessed hlist/whatsit categories via a global tl. The glue branch now only accepts immediately adjacent xeCJK markers (#992). - Removed the dedicated color pending boolean; color push/pop and box output are now handled by transparent/wrapped-box capture (#992). - Wrapped the kernel-private `\@imakebox` and `\@iframebox` `[#1][#2]#3` signatures to register `\makebox`/`\framebox`; this wrapper must be updated if the kernel changes that signature (#992). - Migrated link-annotation entry saving and tail-anchor replay to unified stream capture, restoring boundaries on both sides according to the link's actual visible head/tail class (#992). - Registered `\set@color` and `\reset@color` as transparent captures; removed the dedicated color push/pop marker save/replay branch (#992). - Registered `l3color` color push/pop entries as transparent captures; removed the corresponding dedicated marker protection branch (#992). - Migrated `\HD@target` to unified transparent capture, restoring marker and source-space state on both sides (#992). - Wrapped `\Url@z`'s full formatting phase in a fixed Default head/tail stream capture; removed the #880 dedicated drain (#992). - Migrated `\verb` from the entry drain (which assumed Western output) to unified stream capture, restoring boundaries according to verbatim's actual head/tail class (#992). - Registered `\eqref` as fixed Default head/tail and `\cs` as fixed Default head-only stream captures; codedoc/doc meta internal adapters now directly wrap a fixed Default stream, removing the dedicated drain and covering all its public call sites (#992). - Registered kernel `\@setref` (or `hyperref`-saved `\real@setref`) as auto stream capture, replacing the #991 dedicated saved-node/replay patch with the unified framework. - Changed `\blx@pagetracker` from a one-way state drain to transparent capture, making write whatsits transparent to the actual visible boundaries on both sides (#992). - Integrated xeCJKfntef underline commands, native `ulem` entries (e.g. `\uline`), `\xeCJKfntefon`, and standalone symbol commands into stream capture; internal pending is now published through the framework's unified helper; removed fntef-specific tail-state restoration and pending setup (#992). - Measurement-time box isolation for decorative symbols now uses the framework's nestable pause zones, simultaneously saving and restoring marker and pending state (#992). - Connected `\lstinline`'s delimiter, active-character, and brace scanning paths to auto stream capture, making all four source-space combinations around color switches consistent with direct input (#992).

New on CTAN: concrete-vec
by CTAN Announcements via ctan-ann 26 Jul '26

26 Jul '26

Matthew Lorig submitted the concrete-vec package. Version: License: Summary description: Concrete text and mathematics as outlines, with a synthetic bold weight Announcement text: -------------------------------------------------------------------------------- concrete-vec – Concrete text and mathematics as outlines, with a bold weight concrete-vec typesets a document in Knuth's Concrete fonts with two properties the existing Concrete packages do not jointly provide: every glyph, in text and in mathematics, is a vector outline rather than a bitmap; and a bold weight is available, synthesised by stroking, in both text and mathematics. It is a thin configuration layer over ccfonts, mathastext and pdfrender, and targets pdflatex. Text is set in T1-encoded Concrete (vector via cm-super); mathematics reuses the Concrete text font through mathastext, so math letters, digits and operators are Concrete outlines too. Bold is produced by stroking glyph outlines: the package patches \bfseries so bold works in headings, tables and list labels, and provides \bd{...}, a single command that bolds in both modes — ordinary bold in text, and in mathematics an in-place stroke that thickens any symbol (Latin or Greek) while preserving its shape, so \bd{x} keeps its italic and \bd{\pi} gives a bold pi. This is the first release. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org More information is at https://ctan.org/pkg/concrete-vec -------------------------------------------------------------------------------- Thanks for the upload.

by CTAN Announcements 25 Jul '26

25 Jul '26

Gérard Dubard submitted the texecole package. Version: 1.0 2026-07-23 License: gpl3+ Summary description: A French-prose document composition language Announcement text: ------------------------------------------------------------------------ English: texecole is a new LuaLaTeX document class for teachers who want print-ready worksheets without writing LaTeX. Documents are written in a French-only prose tag language (no anglicisms), which the class translates to LaTeX at compile time. It covers layout frames and grids, tables, images, a math mini-language (fractions, sums, integrals, derivatives, matrices), function plotting, plane and solid geometry, and statistics/probability diagrams. An internal computation engine handles most needs; Python (SymPy/SciPy) can be used for extended symbolic and numeric computation. French: texecole est une nouvelle classe LuaLaTeX construite autour d'un langage de balises en prose française (sans anglicisme), traduit en LaTeX à la compilation. Elle s'adresse à toute personne produisant des documents scientifiques, techniques ou pédagogiques : élèves, étudiants, enseignants, chercheurs, ingénieurs, auteurs de documentation. Elle couvre les cadres et grilles, les tableaux, les images, un mini-langage mathématique (fractions, sommes, intégrales, dérivées, matrices), les graphiques de fonctions, la géométrie plane et les solides, ainsi que les statistiques et probabilités. Un moteur de calcul interne couvre l'essentiel des besoins ; Python (SymPy/SciPy) peut être utilisé pour le calcul formel et numérique étendu. ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/texecole The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/luatex/latex/texecole/ ------------------------------------------------------------------------ Thanks for the upload.
