About HVML/PurC
PurC is a C/C++ interpreter for HVML, a descriptive programming language created by Vincent Wei (author of MiniGUI). It implements all features of HVML Specification V1.0 and predefined dynamic objects as defined in HVML Predefined Variables V1.0. PurC can be used via the command-line tool 'purc' to run HVML programs or as an embeddable library for building custom HVML interpreters. The project is licensed under LGPLv3, making it free for commercial use under the license terms. Currently supports Linux and macOS, with Windows support in development. Version 0.9.30 is the latest release.
