Introduction

flowG: The flowG FunctionGraph IR: types, codegen, runtime, OpDispatch backends, energy receipts.

This is the official documentation for flowG. The full source code lives in the private -core mirror; the public release surface is at openIE-dev/flow-g.

What you'll find here

• Install: get the flowg binary on your machine
• Hello, flowG: first program in 30 seconds
• Tutorial: a 30-minute hands-on guided tour

• Cookbook: task-oriented recipes
• Design: why flowG exists and how it fits with the rest of openIE-dev

The openIE-dev ecosystem

flowG is one of five public openIE-dev projects. All five share a common substrate (flowG) and energy-metering layer (substrate-energy):

• flow-g: the IR + runtime substrate
• lux-lang: reactive language compiling to flowG
• jmax: math-native language
• joule-lang: energy-budgeted compiled language
• jouledb: energy-metered database
