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

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.

CTAN update: tkz-doc
by CTAN Announcements via ctan-ann 21 Oct '26

21 Oct '26

Alain Matthes submitted an update to the tkz-doc package. Version: 1.46c 2026-10-20 License: lppl1.3 Summary description: Documentation macros for the TKZ series of packages Announcement text: -------------------------------------------------------------------------------- ## [1.46c] — 2026/10/20 The text of the documents is the same as with 1.45c (checked page by page on the documentation of tkz-tab, tkz-graph, alterqcm, tkzexample and tkz-doc), but the index changes. ### Changed - The index no longer contains the wrong entries written by `NewMacroBox` (name and arguments together, e.g. `\Edge[local options](Vertex A)...`) and by `NewEnvBox` (`\begin{...}`, `\end{...}`); the correct entries are kept. - `\TeX` is robust again, as in the LaTeX kernel: an index entry that contains `\TeX` (e.g. `\tkzNamePack{Lua\TeX}`) may be sorted differently. - `\tikzstyle` (deprecated) replaced by `\tikzset` for the styles `mybox`, `fancytitle` and `title`. - Identification part (`\NeedsTeXFormat`, `\ProvidesClass`) placed first; LaTeX 2020/10/01 or later is required. - Option `cadre`: `pgfornament` is loaded automatically if the document does not load it (only a warning if it is not installed). - `\url` and `\href` are no longer needed: the cover and `\presentation` use them only if a package (`hyperref`, `url`) defines them. ### Added - `\tkzmailofauthor`: e-mail address used by `\presentation` (default `al.ma(a)mac.com`, as before). - Default values for the colours (`myblue`, `sectioncolor`, `titlecolorbox`, `framecolor`) when `tkz-doc.cfg` is not found, and for the macros `\tkznameofpack`, `\tkzversionofpack`, `\tkzversionofdoc`, `\tkzauthorofpack`, `\tkznamecollection`, `\tkzurlauthor`, `\tkzurlauthorcom`. - The documentation explains the class (options, cover, colours, boxes, macros for names, arguments and index, tables, layout). ### Fixed - `\presentation` can be used more than once (`\newlength` was inside the macro). - `\tkzTitleFrame`: fragile commands in the title no longer break (`\protected@edef` instead of `\edef`). - `\tkzNameMacro` and `\TMline` no longer index their argument twice. - `\tkzSetUpColors` no longer adds spurious spaces. - Duplicate definitions of `\TeX`, `\LaTeX` and `\LATEX` removed. - The KOMA-Script internal `\idx@heading` is redefined only if it exists. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/tkz-doc More information is at https://ctan.org/pkg/tkz-doc -------------------------------------------------------------------------------- Thanks for the upload.

21 Oct '26

Alain Matthes submitted an update to the tkz-tab package. Version: 2.13c 2026-10-19 License: lppl1.3c Summary description: Tables of signs and variations using PGF/TikZ Announcement text: -------------------------------------------------------------------------------- ## [2.13] — 2026/10/05 ### Changed - Keys use `pgfkeys` instead of `xkeyval`: same names, same default values, defaults reset at each call as before (`\tkzTabSetup` included). - `\tkzTabVar`: the 31 symbols are keys `/tkztab/var/<symbol>` (the long cascade of `\ifthenelse` is removed); a new symbol can be added with `\pgfkeys{/tkztab/var/<symbol>/.code={...}}`. - `\tkzTabLine`: the symbols `z`, `t`, `d`, `h` are keys `/tkztab/line/odd/<s>` and `/tkztab/line/even/<s>`. - Useless `\makeatletter`/`\makeatother` removed (`\tkzTabLine`, `\tkzDrawArrow`). - `xkeyval` is no longer loaded: a document that used it without loading it must now load it. ### Fixed - Option `help` of `\tkzTabInit`, `\tkzTabLine` and `\tkzTabVar`: the labels of the nodes failed (`Undefined control sequence`) with the TikZ library `babel` when the picture is inside an environment that reads its content again, such as `tkzexample`. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/tkz/tkz-tab More information is at https://ctan.org/pkg/tkz-tab -------------------------------------------------------------------------------- Thanks for the upload.
