Sysl extension for Visual Studio Code

Accelerate your Sysl spec development with rich language features and interactive side-by-side diagrams.

Features

Syntax

Sysl source syntax highlighting improves the legibility of Sysl specifications.

The Sysl language server provides additional language features, and is implemented in anz-bank/sysl.

Diagrams

Visualize a specification as an interactive diagram in real time.

Requirements

Just Visual Studio Code. The extension will fetch any other dependencies it needs (e.g. the Sysl binary).
