Screenplay Language

Language support for the Cratis Screenplay DSL — the modeling language that describes a complete bounded context (events, commands, queries, projections, screens, automations, authorization, validation, constraints, and concepts) in a single declarative .play file.

Features

• Syntax highlighting for all Screenplay constructs, slice types, concept attributes (@pii, @sensitive), and context variables ($context.*, $env.*).
• Embedded language highlighting — inline csharp, typescript, react, and html blocks between triple backticks are highlighted with their own grammars.
• Sub-language highlighting for the Projection Declaration Language (PDL) inside projection blocks and the Change Data Capture Language (CDL) inside capture blocks.
• IntelliSense — context-aware completions for constructs, clauses, and in-scope symbols: policies after authorize, events after on and produces, file/csharp after handler, concepts and primitives in type positions.
• Hover documentation for keywords, concepts, policies, and events.
• Diagnostics — unknown slice types, unknown primitive types, references to undeclared policies and events, tab indentation, and unclosed code blocks.
• .play files carry the Cratis icon in the explorer and editor tabs.
