CTAN update: tkz-elements

Alain Matthes submitted an update to the

                  tkz-elements

package.

Version:  5.00c 2026-02-17
License:  lppl1.3c

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

Announcement text:
----------------------------------------------------------------------
 
 Docs:
 Major Documentation Restructuring
 The documentation is now structured into four coherent parts:

 Geometry Core
 Algebra and Tools
 Lua and Integration
 Mathematical and Computational Foundations

 This restructuring improves conceptual clarity and clearly separates
 geometric theory from implementation details.

 New Sections:
    Added subsection "Special Characters and Catcodes"
    Added new section:
    Computational Model and Geometric Engine

 Added:

    in line - Added method where_on_line.
   New Classes
     Added class fct (function)
     Added class pfct (parametric function)
     Standard tables introduced: - F → functions - PF → parametric functions
     Added class list_point

 Changed:

 Unified Geometric Position Model

 A major harmonization of geometric relation methods has been introduced.
 Standardized Return Values

 All geometric position methods now consistently return:
     "ON", "IN", "OUT"
     or relation-specific classifications (e.g. "TANGENT", "DISJOINT", etc.)
     Boolean wrappers remain available for backward compatibility.
     line:  New & Updated Methods

 line:position(pt)\ → Returns "ON" or "OUT".
 line:in_out(pt)\ → Boolean wrapper of position.
 line:path(n)\ → Parameter n is now documented.
 circle

 circle:position(obj) now accepts generic objects:
    Relation names are now consistently uppercase:
    point: IN, ON, OUT
    line:  DISJOINT, TANGENT, INTERSECT
    circle:  Extended circle--circle classification

 triangle:
    on_triangle
    New Attributes:  alpha_ , beta_, gamma_, orientation, cross

 angle:  Major development and stabilization. - value and deg are
         now attributes\ (no longer methods).

 path: - path:count() is now documented.
           - tkzSetCountFromPath is now documented.
           - Improved integration between list_point and path.

 New Macros (Graph Support):   For fct and pfct:

    \tkzDrawPointOnGraph
    \tkzDrawPointsOnGraph
    \tkzDrawPointOnParamGraph
    \tkzDrawPointsOnParamGraph
