Version number: 4.30c 2025-10-04
License type: lppl1.3c
Summary description: A Lua library for drawing Euclidean geometry with TikZ or
tkz-euclide
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 “external” or “internal” 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.

tkz-elements – A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide
This package provides a library written in Lua, allowing to make all the necessary calculations to define the objects of a Euclidean geometry figure. You need to compile with LuaLaTeX. The definitions and calculations are only done with Lua.
The main possibility of programmation proposed is oriented “object programming” with object classes like point, line, triangle, circle and now, conic. For the moment, once the calculations are done, it is tkz-euclide or TikZ which allows the drawings.
