Open-source alternatives to VbPeg

Bosque is an experimental programming language and development platform designed for machine-assisted software construction. It combines functional programming semantics with imperative syntax to enforce logic correctness and runtime safety, providing a type-safe environment that utilizes structured data models to maintain information integrity throughout the application lifecycle. The platform distinguishes itself through deep integration with formal verification tools, including automated theorem provers and symbolic execution engines. By transforming source code into a regularized intermed

Extensions to the Tiny Lisp language for embedded applications

The wrapper allows to execute OpenCL code on CPU and GPU devices from VBA. More detailed description with examples can be found in my CodeProject article.

This library provides several tools useful for writing lexers / parsers in Ada.
