Kona is an open-source C implementation of the K (k3) programming language, an APL/LISP-derived array language originally from Kx Systems. It provides a command-line interpreter for the k3 dialect, which is no longer commercially available.
Use cases
- run k3 scripts without a proprietary Kx license
- learn the K array programming language
- analyze large datasets with vectorized array operations
- prototype trading and financial analytics in K
- study Arthur Whitney's terse C coding style
- experiment with APL-style list-based programming in ASCII
When to choose
- you need a free, open-source k3 interpreter
- you want to learn or teach the K language
- you work with array/vector-style data analysis and prefer terse notation
When to avoid
- you need production support or k4/q compatibility - use KDB+ from Kx
- you need a modern, actively developed language ecosystem
- you want multi-dimensional APL arrays rather than K's list-based model
