The Vireo project provides a subset of LabVIEW runtime functionality for small targets. Example usages are WebVIs and the EV3 support in the _LabVIEW Module for LEGO® MINDSTORMS®_. The LabVIEW features supported are primarily defined by the features needed for the VIA files generated by [G Web Development Software](https://www.webvi.io/). # Development - [Workflow](docs/Workflow.md) - Getting started workflow for setting up a GitHub fork and local development environment. - [Build](docs/Build.md) - Platform-specific instructions for building Vireo. - [Test](docs/Test.md) - Instructions for running tests and creating new tests. - [Coverage](docs/Coverage.md) - How to gather test coverage reports. - [Coding Guidelines](docs/CodingGuidelines.md)- Guiding principles for Vireo development. - [Design Notes](docs/DesignNotes.md) - Record of major design decisions. # Learning - [The Big Picture](docs/Intro.md) - What is Vireo and HelloWorld examples. - [Introduction to types and functions](docs/IntroTypeExamples.md) - Basic Vireo type system examples. - [Introduction to parallel execution](docs/IntroParallelClumpExamples.md) - Vireo parallelism primitives. - [Introduction to arrays](docs/IntroArrayExamples.md) - Description of Vireo's different Array representations. - [The Type Manager](docs/TypeManager.md) - Understanding the Type Manager that manages all types and data allocations. - [VIA EBNF](docs/ViaEBNF.md) - EBNF grammar for VIA assembly. # License and copyright Copyright (c) 2020 National Instruments Licensed under the [MIT License](LICENSE.txt).
