Guide
Start with the language tour, learn Frothy's core concepts, or jump into a focused guide.
Frothy in Y Minutes
The complete Frothy language in one runnable, example-first page: values, words, state, control flow, records, errors, events, persistence, and the prompt.
Frothy Concepts
A structured path through Frothy's mental model, from the first prompt to hardware, persistence, and native extensions.
Boards
The boards that run Frothy, how each one connects, and the boards that do not work.
Coming from Arduino
How the parts of an Arduino sketch map to Frothy words, and which boards work.
Limits
The fixed sizes of a Frothy board, and what to do when one is full.
Modules
Start with a complete example, then narrow into every built-in Frothy module and its words.
Device & Sessions
Prompt sessions, control sessions, diagnostics, persistence, boot, and recovery on a Frothy device.
Extending Frothy
Use libraries, write pure Frothy libraries, and add native words when C is required.
Toolchain
CLI, project/build files, flashing, sending source, and editor integration.
Porting to a new target
Bring Frothy to a new MCU by implementing one platform header.
Agent Guide
Rules for an AI model that writes Frothy code: the syntax, the words that do not exist, the limits, and how to send code.
