Tutorials

Two tracks. Each is read in order, and each chapter builds on the ones before it. Both need the Quickstart done first, so the koskari command starts a REPL.

Little Koskari

For readers new to programming. Every chapter is a dialogue: a question on the left, the answer on the right, with the code in the answer. It starts with words and punctuation and ends with a small program in a file. Start here.

From Python

For readers who know Python. Each chapter sets the Python spelling beside the Koskari one and then says what changed. The later chapters cover classes, modules, errors, interop, and macros, and the track ends with worked examples to copy and change. Start here.

Both tracks lead into the Guide, which explains each mechanism in depth. Neither needs the reference open; where a chapter names a form, it links to that form’s page.
