MathParser

An expression parser and a virtual machine. A formula is compiled to a flat byte array and evaluated by a linear pass over it, with no allocation on the path of an ordinary formula. On x86-64 an optional accelerator compiles that bytecode to machine code and hands anything it declines back to the interpreter, so an answer is never fast but wrong. Results are cached by shape: once 2 + 3 has been compiled, 5 + 7 reuses the same script and only writes the numbers into a copy. 163 functions to call and 249 names in the table, your own functions and variables bound by address, symbolic differentiation. The Lazarus parser packages require FCL and define NOFORMS and NOGRAPHICS, so they install without LCL. WebAssembly uses a separate console configuration. Two units ask for more at their defaults, Thread through Application.HandleException and BlobManager through TGraphic; drop the defines and add the LCL to the package if you want them.

Waskal

Waskal is a Pascal/Oberon-inspired language that compiles to wasm64 and packages code, assets, and runtime support into a single self-contained HTML file. It uses JavaScript to bridge WebAssembly with browser graphics, audio, and input, delivering portable, dependency-free apps and games with a simple double-click-and-run experience.

raylib-pas

A complete header translation (binding) of the raylib 2.6.0-dev to Pascal. Without any funky helper functions for memory alignment issues. Inspired and partially based on the drezgames/raylib-pascal binding, however a little cleaner and more recent, with FPC 3.0.4 support.

CrossGraph

A plotting engine and a visual component that draw what MathParser computes: curves with their discontinuities, intersections and extrema, cartesian and polar systems, and surfaces z = f(x, y) with contour lines. The engine samples on worker threads, knows nothing about a canvas and builds headless; the component is a thin layer over it. Free Pascal 3.2.2 and newer builds it: the sort in CrossVision.Geometry that once needed function references is written out in the same unit. Delphi 10.2 Tokyo and newer builds it as well.

a WFC demonstrator project that revolves around a factory that rebuilds itself while maintaining production. The player rebuilds a crawler carrying a salvage factory across the salt flats. Each settlement needs a different combination of products. The factory travels with its inventory, upgrades and scars; the player decides how it evolves.
