Imandra Protocol Language

Provides real-time syntax highlighting, bracket matching, and code folding for Imandra Protocol Language specifications within VSCode's editor. The extension registers IPL as a language with VSCode's language definition system, enabling color-coded visualization of state definitions, message schemas, action declarations, and constraint expressions. This allows developers to write formal specifications with visual feedback on language structure without requiring external tools.

Enables developers to define financial system interfaces as executable formal specifications using IPL's state machine model. Specifications consist of state definitions (global variables), inbound message schemas with validity constraints, internal action definitions, and outbound message definitions. The language compiles these specifications into a machine-readable format that can be consumed by the Imandra automated reasoning engine for verification, test generation, and simulation without requiring manual test case authoring.

The extension acts as a specification authoring interface that produces .ipl files designed to be consumed by the separate Imandra automated reasoning tool. While the extension itself provides no reasoning capabilities, it structures specifications in a format that Imandra can process for model checking, symbolic state space exploration, automated test case generation with coverage explanations, and production data auditing. The extension enables the workflow of writing specifications in VSCode and then exporting them for external analysis without manual format conversion.

Provides an integrated reference dictionary within VSCode that documents IPL language constructs, FIX protocol message types, and formal specification patterns. The dictionary enables inline documentation lookup, code snippets for common specification patterns, and contextual help for constraint syntax and state machine definitions. This reduces context-switching between the editor and external documentation, allowing developers to author specifications without leaving VSCode.

Provides VSCode theme and icon set customizations optimized for IPL specification authoring, including color schemes for formal specification syntax, icon themes for file types and language constructs, and visual styling for state machine and message definitions. These customizations improve visual distinction between different specification elements and reduce cognitive load when working with formal specifications for extended periods.

The extension is offered as freemium software, providing free access to core IPL syntax highlighting, editing, and specification authoring capabilities within VSCode. Premium features (if any) and Imandra reasoning engine access are likely available under separate licensing. This model enables developers to author specifications at no cost while monetizing advanced verification and test generation features through the separate Imandra product.
