CTAN update: runtexshebang
by CTAN Announcements 22 Oct '26

22 Oct '26

Munehiro Yamamoto submitted an update to the runtexshebang package. Version: 1.1 2026-10-21 License: lppl1.3c Summary description: A Lua script running LaTeX document files with TeX-style shebang Announcement text: -------------------------------------------------------------------------------- runtexshebang v1.1 refuses a TeX-style shebang (%#!) line that contains an ASCII control character other than TAB, both when running it and with --dry-run. A carriage return or an escape sequence in that line could make the command shown on the terminal differ from the command the shell actually runs. Non-ASCII bytes are not checked, so UTF-8, Shift_JIS and EUC-JP file names keep working. The test suite now also checks that runtexshebang never loads Lua modules placed in the current directory. runtexshebang 1.0 runs the `%#!` line of a LaTeX document through the system shell, as before, but is now more careful about it. ## Changes - The license is now the LaTeX Project Public License 1.3c (was MIT). - The command of the `%#!` line is printed on stderr before it is run, and its exit status is passed through, so editors and `make` can detect failures. - CRLF line endings and a UTF-8 byte order mark before `%#!` are handled; only the leading `%#!` is removed from the line. - Missing files, an empty `%#!` line and unknown options are reported with a message and a non-zero exit status instead of a Lua traceback. `--` ends option parsing. - On Windows, `NoDefaultCurrentDirectoryInExePath=1` is set before the command runs, so an executable placed next to the document cannot shadow a TeX Live program named on the `%#!` line. - The README has a new Security section. In short: running runtexshebang on a document is equivalent to typing its `%#!` line yourself, so use it only on documents you trust, and never add it to `shell_escape_commands`. - PDF documentation is included. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/support/runtexshebang More information is at https://ctan.org/pkg/runtexshebang -------------------------------------------------------------------------------- Thanks for the upload.

New on CTAN: footnotenosplit
by CTAN Announcements via ctan-ann 21 Oct '26

21 Oct '26

Munehiro Yamamoto submitted the footnotenosplit package. Version: 1.0 2026-10-20 License: lppl1.3c Summary description: Suppress orphan footnote rules when footnotes are not allowed to split Announcement text: -------------------------------------------------------------------------------- # footnotenosplit v1.0 Initial release. Setting `\interfootnotelinepenalty=10000` keeps footnote text from being split across pages: a footnote that does not fit is moved to the next page as a whole. This policy, common in book production, can leave a lone `\footnoterule` — with no footnote text below it — at the bottom of the original page, and the moved footnote sits too close to the rule on the next page. footnotenosplit suppresses both side effects. Supported formats/engines: pdfLaTeX, LuaLaTeX, XeLaTeX (LaTeX2e 2025-06-01 or later), pLaTeX and upLaTeX. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/footnotenosplit More information is at https://ctan.org/pkg/footnotenosplit -------------------------------------------------------------------------------- Thanks for the upload.

21 Oct '26

Lukas C. Bossert submitted an update to the dfg-crc package. Version: 0.3.0 2026-10-20 License: lppl1.3c Summary description: Create DFG Collaborative Research Centre proposals and CVs Announcement text: -------------------------------------------------------------------------------- Version 0.3.0 updates the project-leader equality table in section 1.4.2 B to follow the revised DFG form 60.200, with female-only figures by default and first-funding-period numbers and percentages for third-period proposals. The manual and README document commands for retrieving counts, category totals, and percentages in prose. Statistics remain consistent when switching funding periods inside grouped calls. The overview defaults to female-only DFG columns; printTable[all-sexes]{GenderEqualityProjectLeaders} selects f/m/d figures for all three periods for that table only. Put table options before the table specification. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/luatex/latex/dfg-crc More information is at https://ctan.org/pkg/dfg-crc -------------------------------------------------------------------------------- Thanks for the upload.

21 Oct '26

Alain Matthes submitted an update to the tkz-berge package. Version: 2.20c 2026-10-20 License: lppl1.3c Summary description: Macros for drawing graphs of graph theory Announcement text: -------------------------------------------------------------------------------- ## [2.20c] — 2026/10/20 ### Changed - Keys use the pgfkeys layer of tkz-graph instead of `xkeyval`: same names, same default values, same results. - The macros call the internal commands of tkz-graph (`\tkzgr@Vertex`, `\tkzgr@Edge`, `\tkzgr@Edges`), not the short names. - Needs tkz-graph 2.20c (2026-10-20) or later; an error is raised otherwise. - `\grHypercube[options]{n}`: hypercube Q_n; vertices named by their binary word (`a000`, `a001`...); classic drawings for n = 1 to 4. - `\grTree[options]{k}{depth}`: complete k-ary tree; vertex j of level l named `<prefix>l;j`. ### Examples - NamedGraphs examples: each file has its own preamble (no more `\input{tkzpreamblenamed.ltx}`); `tkzNamed-12-2-0` loads `xcolor` with `dvipsnames`, `tkzNamed-15-2-0` declares its counter `tempi`. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/tkz/tkz-berge More information is at https://ctan.org/pkg/tkz-berge -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: tkz-graph
by CTAN Announcements 21 Oct '26

21 Oct '26

Alain Matthes submitted an update to the tkz-graph package. Version: 2.20c 2026-10-20 License: lppl1.3 Summary description: Draw graph-theory graphs Announcement text: -------------------------------------------------------------------------------- ## [2.20c] — 2026/10/20 ### Changed - Keys use `pgfkeys` instead of `xkeyval`: same names, same default values, same results. The behaviour of `\presetkeys` is kept (preset values apply only to the keys not given; `\SetVertexMath`, `\SetUpEdge`, `\GraphInit`... still change them). - `xkeyval` is no longer loaded: a document that used it without loading it must now load it. - `vstyle` and the `dir` key of `\grLoop` accept a macro as value. - The short names (`\Vertex`, `\Vertices`, `\Edge`, `\Edges`, `\Loop`, `\EA`, `\WE`, `\NO`, `\SO`, `\NOEA`, `\NOWE`, `\SOEA`, `\SOWE`) are installed at the beginning of each `tikzpicture`. A definition of `\EA`, `\NO`... made elsewhere (by the user or another package) keeps its meaning outside the pictures. If such a name is already defined when tkz-graph is loaded, a warning gives the prefixed name. - The code calls only internal commands (`\tkzgr@...`); tkz-berge does the same. - Each `vstyle` is a pgfkeys key (`/tkzgraph/vstyle/<name>`). - Internal macros protected; `\ifthenelse` no longer used internally (`ifthen` is still loaded); `etex` removed; `\fileversion` and `\filedate` are no longer redefined. ### Fixed - `\AddVertexColor` and `\Vertices` no longer depend on global helper macros (`\deb`, `\fin`, `\v`, `\liste`...). - A second `\GraphInit[vstyle=...]` in the same group was ignored and wrote its value in the text (the internal macro `\GR@init@vstyle` overwrote the key itself). ### Added - Prefixed names, always available: `\tkzVertex`, `\tkzVertices`, `\tkzEdge`, `\tkzEdges`, `\tkzLoop`, `\tkzEA`, `\tkzWE`, `\tkzNO`, `\tkzSO`, `\tkzNOEA`, `\tkzNOWE`, `\tkzSOEA`, `\tkzSOWE`. - Package option `noshortnames`: the short names are never defined. - `\tkzDefGraphStyle{<name>}{<code>}` defines a new style for `\GraphInit[vstyle=<name>]` (name case insensitive). - `\tkzSetUpGraph[...]`: local settings of the vertices, edges and labels (`vertex shape`, `vertex line width`, `vertex line color`, `vertex text color`, `vertex fill`, `light fill`, `dark fill`, `ball color`, `inner sep`, `outer sep`, `small size`, `medium size`, `big size`, `edge color`, `edge width`, `edge fill`, `art color`, `double distance`, `label text`, `label fill`, `unit`), `directed` (an arrow on every edge) and `arrow tip`. It replaces the `\renewcommand` of `\VertexShape`, `\EdgeLineWidth`... - Keys `->`, `<-`, `<->`, `-` and `arrow` for `\Edge` and `\Edges`. - Keys `rotation` (angle of the first vertex) and `clockwise` for `\Vertices{circle}`. - `\tkzHighlightPath[options]{A,B,C}` (path, option `cycle`) and `\tkzHighlightPath{A/B,C/D}` (edges): edges drawn again over the graph (`color`, `lw`, `style`). - `\tkzAdjacencyMatrix[options]`: adjacency matrix of the graph of the last picture (options `directed`, `order`). - `\tkzGraphFromMatrix[options]{A,B,C}{0,1,1;1,0,1;1,1,0}`: graph (vertices on a circle, or `placed`) from a matrix; options `directed`, `weighted`, `unit`, `rotation`, `clockwise`, `style`, `loop distance`, `bend`. - `\grProbMatrix{A,B,C}{matrix}`: probabilistic graph with any number of states, from the transition matrix. ### Compatibility - Same rendering for the existing documents. `arrows.meta` is not loaded (it changes slightly the default tip); load it to use `arrow tip=Stealth`. - tkz-berge must be 2.20c or later (older versions need `xkeyval`). -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/tkz/tkz-graph More information is at https://ctan.org/pkg/tkz-graph -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: tkzexample
by CTAN Announcements 21 Oct '26

21 Oct '26

Alain Matthes submitted an update to the tkzexample package. Version: 1.51c 2026-10-20 License: lppl1.3 Summary description: Package for the documentation of all tkz-* packages Announcement text: -------------------------------------------------------------------------------- ## [1.51] — 2026/10/20 ### Added - New key `break code` (`auto`, `fill`, `always`, `never`): a long code can be split across pages. The line numbers (`num`), the background (`code`) and the frame (`frame code`) continue on the following pages. `break code=never` gives the behaviour of 1.45c (unbreakable box). ### Fixed - The key `above skip` works (it had no effect). - The options may contain `\par` (e.g. `above skip=\par\vspace{1cm}`). ## [1.50] — 2026/10/05 ### Changed - The brackets `[]` after `\begin{tkzexample}` are optional. - `xcolor` and `pgfkeys` are loaded: `tkzexample` can be used without `tikz`. ### Fixed - `overhang=false` works again (duplicate key removed). - The keys `inner right margin` and `inner bottom margin` are used. - `tkzltxexample`: the key `hsep` no longer overwrites the dimen `\tkz@hsep`. - Keys `latex` and `vbox`: an end of line in the code is a space again and an empty line starts a new paragraph (the words of two lines were glued together). - Option `saved`: - with `code only`, the code is printed and not the name of the file; - no more overflow of 6pt when the code is placed under the result; - several examples in the same subsubsection no longer overwrite each other (`tkzFile-1-2-0.tex`, `tkzFile-1-2-0-2.tex`, ...); - `\tkzSavedCode` works without brackets. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/tkz/tkzexample More information is at https://ctan.org/pkg/tkzexample -------------------------------------------------------------------------------- Thanks for the upload.

New on CTAN: tkz-fn
by CTAN Announcements 21 Oct '26

21 Oct '26

Alain Matthes submitted the tkz-fn package. Version: 1.00c 2026-10-19 License: lppl1.3c Summary description: Draw graphs of functions in 2D, using TikZ and LuaLaTeX Announcement text: -------------------------------------------------------------------------------- tkz-fn draws graphs of functions with TikZ; all computations are done by Lua, so the package requires LuaLaTeX. It is the successor of tkz-fct: gnuplot, fp.sty, tkz-base and --shell-escape are no longer needed. All macros begin with \tkzFn, so tkz-fn and tkz-fct can be loaded together. Features: - curves y = f(x), parametric and polar curves, interrupted at vertical asymptotes and where the function is not defined; - tangent lines (with one-sided tangents), areas under or between curves, Riemann sums (left, right, mid, inf, sup); - points on curves, coordinates, labels, vertical and horizontal lines, data plots; - values, derivatives, integrals and Riemann sums computed by Lua and printed in the text; - numbers in American (3.14, (a, b)) or French (3,14, ]a ; b[) format; - axes as in school textbooks, with arrows at one or both ends, or "box" axes as with pgfplots, selected by an option; - optional bridge to tkz-elements: points defined by tkz-fn are exported to the table z. The documentation is available in American English (tkz-fn-en.pdf) and in French (tkz-fn.pdf). -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/tkz/tkz-fn More information is at https://ctan.org/pkg/tkz-fn -------------------------------------------------------------------------------- Thanks for the upload.
