kharp – k version 3 Language Interpreter in C#
kharp-k is a C# implementation of the K version 3 programming language, part of the APL family, currently in beta release. It supports core language features including vectors, functions, I/O, and a foreign function interface for .NET integration. The software is licensed under the MIT License with Commons Clause, allowing broad use but prohibiting direct commercial sale.
- ▪The interpreter fully implements the K version 3 core language as defined in the K Reference Manual.
- ▪It includes enhancements such as a Foreign Function Interface (FFI) for .NET, object instantiation, and a hint system.
- ▪The project is in beta, with 100% test pass rate, but lacks debugging tools and has known parsing limitations.
- ▪Performance is not on par with native K implementations due to reliance on the .NET runtime and managed memory.
- ▪The software is provided 'as is' with no liability for data loss, and users are responsible for data integrity and backups.
