An modern and pluggable logging framework for Delphi

TaurusTLS provides OpenSSL 3.x and 4.x support for Indy - Internet Direct

Cross-platform console library

An expression parser and a virtual machine for Object Pascal. A formula compiles to a flat byte array and runs by a linear pass over it, with no allocation on the path of an ordinary formula. On x86-64 an optional accelerator turns that bytecode into machine code and hands back anything it declines, so an answer is never fast but wrong. 199 registered names, user functions and variables bound by address, symbolic differentiation. Depends on the RTL alone: no VCL, no FMX.
