Yuriy Pisarev

I write Object Pascal and build tools for Delphi and Free Pascal.

CrossPascal

I'm building CrossPascal to run trained models and process images in Delphi and Lazarus applications. It uses Apache TVM for model inference and includes Pascal bindings for OpenCV and Leptonica.

The Windows x64 releases include examples for resizing images, detecting objects, and asking a model about a photo. Run the example's Prepare.cmd to download its dependencies and sample files.

Browse the examples or download CrossPascal.

Math and plotting tools

  • pascal-mathparser compiles expressions to bytecode. The virtual machine evaluates ordinary formulas without allocating memory. An optional x86-64 accelerator compiles supported bytecode to machine code and falls back to the virtual machine when needed. Supports Delphi 10.2 Tokyo through Delphi 13 and Free Pascal 3.2.2 and 3.3.1 on Windows and Linux.
  • pascal-crossgraph draws Cartesian and polar curves, marks discontinuities, intersections and extrema, and plots surfaces with contour lines. The plotting engine can run without a canvas.
  • graphbuilder-npp plots formulas from a line in Notepad++ and marks roots and extrema. It can open a Markdown report with the SVG plot in a new tab.
  • mathparser-live runs the math and plotting tools in the browser via WebAssembly. Try the demo.

These four projects use the MIT license.
