TRURL is a class library for Object Pascal supporting the creation of virtual calculators with reverse Polish notation (RPN). It comes with demo projects and several ready-to-use calculators for macOS, Linux and Windows.
TRURL is an acronym for "TRURL is a Reusable Universal RPN Library".
Class libraries
Currently, TRURL contains two independent class libraries:
- RPN Engine: This is a full-featured calculation engine as a basis for Pascal-based RPN calculators
- Segmitator: Library for virtual seven-segment displays (may be used independently of the RPN Engine)
Calculators
The following applications are available from the TRURL project:
- TRURL A: Simple demo app for the RPN Engine
- TRURL G: Desktop RPN calculator inspired by the user interface of the DSKY unit of the Apollo Guidance Computer (AGC)
Additional calculators may be available from third parties
