Thinking in K: A Practical Guide to Array Language Programming with ngn/k
By
tosh
Slow-proofed and worth the wait. Worth its weight in flour.
Summary
A tutorial chapter from the ngn-k-tutorial on GitHub that introduces the concept of "thinking in an array language" using K. It covers practical REPL-based programming workflows, the use of ngn/k with rlfe for history navigation, testing functions interactively before moving to production code, and leveraging ngn/k's prettyprinting feature which always returns valid K data for precomputation to optimize programs.
Key quotes
· 3 pulledMost K programming happens through the REPL, because it is very useful to iterate upon previous code.
Functions are tested in the REPL, and then moved to actual code.
ngn/k's prettyprinting always returns valid k data, and you can precompute some things beforehand to speed up your program.
