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.
