Alain Matthes submitted an update to the

tkz-elements

package.

Version: 4.20c 2025-09-17
License: lppl1.3c

Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide

Announcement text: ----------------------------------------------------------------------

New triangle methods: thebault/c_c (Th|-baultrCOs problem III),
mixtilinear_incircle, three_tangent_circles, morley, soddy,
napoleon, poncelet_point, orthopole; plus orthopole support
for quadrilaterals via helper tkz.orthopole(a,b,c,l).

Improvements: circle (common_tangent, orthogonal_through,
orthogonal_from, c_cc_p), line (distance), and rewritten
triangle methods (symmedian_line, altitude, bisector,
bisector_ext, mediator, ex_circle, reflection).

Docs: new Best practices subsection, additional examples
(Th|-bault III, Poncelet point for triangle/quadrilateral,
orthopole), and assorted fixes.
Backward compatible.

Docs

Changed the names of the examples.
The examples now use external Lua files.
Corrected the documentation.
Cleaned up the files: unused labels have been removed, as well as overfull box.

package.

Version: 4.25c
License: lppl1.3c

Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide

Announcement text: ----------------------------------------------------------------------

Added
path: get_point, iter().
tkz-elements.sty: three macros \tkzGetPointFromPath(#1,#2){#3};
\tkzPathCount(#1){#2}; \tkzDrawFromPointToPath.
tkz: Function tkz.parabola(a, b, c) to obtain the quadratic form
whose graph passes through the three points a, b, and c
(under certain conditions).

Changed
Source structure: Removed version numbers and dates from each
tkz_elements_xxx.lua file. The official version and release date
are now maintained only in:
tkz-elements.sty (for LaTeX users), README.md, CHANGELOG.md,
doc/tkz-elements.pdf.
occs: The coordinates method now returns numbers instead of strings
(removed checknumber_).
path: Improved get_number_path method.

Docs
Renamed several examples: the old names were more explicit.
After Overview, added three navigation tables (attributes, methods,
metamethods) for each class. All elements should now be listed,
with links to their definitions and, where relevant, to examples.
Rewrote the section on path.
Added in Theorems: CirclerCoPoint Midpoint Theorem.
Added documentation for the new macros of tkz-elements.sty.
Added in Examples: Construction of the midcircle of two disjoint circles.

Announcement text: ----------------------------------------------------------------------


[2025/10/04 version 4.30c]

Added

- circle:
- in_disk same as in_out_disk
- on_circle same as in_out
- in_disk_strict
- out_disk_strict
- line
- side_line This method assigns a value of -1, 0, or 1 to a given
point depending on its position in the plane relative to the
line.
- on_line = in_out_line
- on_segment = in_out_segment ### Changed
- circle
- common_tangent Complete rewriting of the procedure, which now
takes into account the position of circles and, above all, adds
an option to choose between external tangents and internal
tangents when they exist.
- c_cc_p Complete rewriting of the procedure. You can use an
rCLexternalrCY or rCLinternalrCY option to determine whether solution
circles exist. The method takes into account the relative
position of the circles.
- line
- c_ll_p(L, p) now has a line and a point as its argument.

Docs

- Correction of typography.
- Adjusting documentation for new methods.
- Rewriting of numerous method presentations.
