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.
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.
