CTAN update: bundledoc
by CTAN Announcements 27 Feb '25

27 Feb '25

Scott Pakin submitted an update to the bundledoc bundle. Version: 3.5 2025-02-26 License: lppl1.3c Summary description: Bundle together all the files needed to build a LaTeX document Announcement text: ---------------------------------------------------------------------- bundledoc is a post-processor for the snapshot package that bundles together all the classes, packages, and files needed to build a given LaTeX document. It reads the .dep file that snapshot produces, finds each of the files mentioned therein, and archives them into a single .tar.gz (or .zip, or whatever) file, suitable for moving across systems, transmitting to a colleague, etc. As an added bonus, this distribution includes a small script called arlatex. arlatex is a LaTeX-specific archiving program that combines a bunch of files into a single .tex file. When the .tex file is run through latex, all of the original files are recreated and the LaTeX document is built. bundledoc can be easily configured to use arlatex as its archiver in place of tar, zip, etc. Version 3.5 of bundledoc is more robust to filenames containing characters that are special to the shell. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/bundledoc The package’s files themselves can be inspected at https://mirrors.ctan.org/support/bundledoc/ ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: expltools
by CTAN Announcements 26 Feb '25

26 Feb '25

Vít Starý Novotný submitted an update to the expltools package. Version: 2025-02-25 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: ---------------------------------------------------------------------- Version: 2025-02-24 ### explcheck v0.7.0 #### Development - Generate a static web site for the exploration of issues in all expl3 files from TeX Live. (discussed with @norbusan and @koppor in #28 and #32, implemented in <https://github.com/koppor/explcheck-issues> by @koppor) The web site is available here: <https://koppor.github.io/explcheck-issues/>. - Add support for config file sections `[filename."=E2=80=A6"]` for specifying file-specific configuration. (#32, #57, #62) For example, here is how you might configure a file `expl3-code.tex` from your configuration file `.explcheckrc`: ``` toml [filename."expl3-code.tex"] expl3_detection_strategy =3D "always" ignored_issues =3D ["w200", "w202", "e209"] max_line_length =3D 140 ``` - Pre-configure well-known files from current TeX Live with more than 100 error detections in <https://koppor.github.io/explcheck-issues/>. (#32, #57, #62) - Add command-line option `--error-format` and Lua option `error_format`. (discussed with @koppor in koppor/errorformat-to-html#2, added in #40, 5034639, and #43) This allows users to specify Vim's quickfix errorformat used for the machine-readable output when the command-line option `--porcelain` or the Lua option `porcelain` is enabled. - Add command-line option `--expl3-detection-strategy` and Lua option `expl3_detection_strategy`. (drafted and discussed with @koppor in #38, added in #49) - Add command-line option `--make-at-letter` and Lua option `make_at_letter`. (discussed with @zepinglee in #30 and #36, added in #61) These options determine how the at sign (`@`) should be tokenized. The default value `"auto"` automatically determines the category code based on context cues. #### Fixes - Prevent false positive E102 (Unknown argument specifiers) detections for control sequences with multiple colons (`::`). (#62) - Ensure that whole files are considered to be in expl3 when the Lua option `expl3_detection_strategy` is set to `"always"`, even when the files contain standard delimiters `\ProvidesExpl*`. (#62) This also prevents false positive E102 (expl3 material in non-expl3 parts) detections. - Only report warning S103 (Line too long) in expl3 parts. (#38, #49) - In machine-readable output, report the line and column number 1 for file-wide issues. (reported by @koppor in #39, fixed in #40) - Exclude comments from maximum line length checks. (reported by @muzimuzhi in #27, fixed in #43, #58, and #59) This includes spaces before the comments. - Always accept both lower- and upper-case issue identifiers. (reported by @muzimuzhi in #26, fixed in #44) This includes Lua options and configuration files, in addition to command-line options and inline TeX comments. - Exclude "weird" argument specifiers (`:w`) from warning W200. (reported by @muzimuzhi in #25, fixed in #45) - Remove error E203 (Removed control sequences). (reported by @koppor in #53, fixed in #54) - Fix two instances of explcheck crashing while processing input files. (reported by @koppor in #31, fixed in #52 and #59) - Do not recognize `@` as a part of an expl3 control sequence. (reported by @zepinglee in #30 and #37, fixed in #60) This prevents warnings S205 and S206 for LaTeX2e control sequence (re)definitions. #### Deprecation - Deprecate the command-line option `--expect-expl3-everywhere` and remove the Lua option `expect_expl3_everywhere`. (#49) Use the command-line option `--expl3-detection-strategy=3Dalways` or the corresponding Lua option `expl3_detection_stragegy=3D "always"` instead. - Deprecate the default config file section `[options]`. (#62) Rename the section to `[defaults]` instead. #### Documentation - Add SPDX license identifier to `README.md`. (added by @koppor in #50) - Link a list of all currently supported issues from `README.md`. (added by @koppor in #51) - Link <https://koppor.github.io/explcheck-issues/> from `README.md`. (#28, #32, b774ba77) #### Continuous integration - Continuously run explcheck on all packages in historical TeX Live Docker images. (suggested by @hansonchar in #28 and #31, added in #52 and #56) - Use ShellCheck to check code style of Bash scripts. (#61) #### Housekeeping - Make off-by-one errors less likely when working with byte ranges. (#47, #48, 13ebfc6e, a0923d06) #### Artwork - Add artwork by https://www.quickcartoons.com/ to directory `artwork/`. (566769b) Version: 2025-02-25 ### explcheck v0.7.1 #### Development - Add support for config file sections `[package.…]` for specifying package-specific configuration. (#32, #57, #62, #63) For example, here is how you might configure the file `expl3-code.tex` from the package `l3kernel` in your configuration file `.explcheckrc`: ``` toml [package.l3kernel] expl3_detection_strategy = "always" ignored_issues = ["w200", "w202", "e208", "e209"] max_line_length = 140 ``` - Add value `"never"` for the command-line option `--expl3-detection-strategy` and the Lua option `expl3_detection_strategy`. (#63) - Pre-configure all remaining expl3 files from current TeX Live with more than 1 error in <https://koppor.github.io/explcheck-issues/>.

CTAN update: tkz-elements
by CTAN Announcements 26 Feb '25

26 Feb '25

Alain Matthes submitted an update to the tkz-elements package. Version number: 3.30c License type: lppl1.3 Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide Announcement text: ---------------------------------------------------------------------- Major evolution of tkz-elements with the introduction of the "conic" class, which replaces the "ellipse" class. - The latter was based on the "ellipse" operation, whereas "plot coordinates" is now used to construct all conic sections: parabolas, hyperbolas, and ellipses. It is worth noting that the circle, although a conic section, is not included in this class. Its significance grants it a special status and a dedicated class of its own. - Another class has been introduced: the "occs" class (orthonormal Cartesian coordinate system). To simplify the construction of conic sections, it was necessary to use well-suited coordinate systems. - A major change is the removal of scaling within the "Lua" section. Initially, I was in favor of avoiding scaling in the "TikZ" part, but since most calculations were already performed there, I realized that it was significantly simpler to apply scaling within the tikzpicture environment. Technical complexities sometimes arise when scaling is handled in the "Lua" section, so I decided to remove this option. Modifications: - In the "regular_polygon" class, I renamed the item "table" to "vertices," which is more appropriate and I also removed the "first" and "next" items, as they were unnecessary. -Correction of the code for the intersection of two circles, which did not provide an appropriate response in cases where no intersection was possible. - Improvement of the code for the "euler_line" method of the class "triangle". - Improvement of the code for the "is_orthogonal" method of the class "line". Additions:: - Major additions: the "conic" and "occs" classes. - An object of the "conic" class is created using the following arguments: focus, directrix, and eccentricity. - The available methods are: points, point, antipode, tangent_at, tangent_from, intersection, in_out, orthopedic, and asymptotes. - The 'points' method, common in many classes, allows creating a set of coordinates defining an object (e.g., a conic), extending the 'point' method which creates individual points. - The functions EL_points, EL_bifocal, HY_bifocal, PA_dir, and PA_focus provide the necessary arguments depending on the given data and the conic section being constructed. - The transformations "projection_ll" and "affinity" are now available for the "line" class. - The creation of an object from the "occs" class is done using the data of a line and a point. This point will be the origin of the new coordinate system, while the line will define the direction of the new y-axis. - The 'kimberling' method allows the creation of some points using this notation with the 'triangle' class. - The methods: steiner_line, simson_line, fermat-axis, brocard_axis, lemoine_axis, orthic_axis and orthic_axis_points complete the methods of the triangle class, as well as the anticomplementary or anti method, the taylor_circle and the taylor_points methods. - Two macros for the 'tikzpicture' part have been created: \tkzDrawCoordinates for obtaining a curve from a table of coordinates and \tkzDrawPointOnCurve for placing a point on such a curve. About documentation: Removal of all “overfull boxes”. Added examples concerning new features Corrected some examples, such as the Euler line. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/tkz/tkz-elements More information is at https://www.ctan.org/pkg/tkz-elements ------------------------------------------------------------------------ Thanks for the upload.
