- Define new package @ethdebug/pointers - Setup TS build system and Jest test suite - Ensure `yarn start` includes those - Define Pointer family of TypeScript types - Use namespaces to reflect schema hierarchy (Pointer.Region, etc.) - Provide type guards for detecting conformance to these types - Define Machine and Machine.State interfaces to adapt external EVMs - Define Cursor interface for inspecting machine state for a pointer - Include `view(state: Machine.State): Promise<Cursor.Regions>` - Define Cursor.Region as a region with all expressions evaluated - Define Cursor.Regions as an array-like collection of regions - Implement read functionality for a Cursor.Region - Implement evaluate functionality for a Pointer.Expression - Implement dereference functionality to get a Cursor from a Pointer - Include integration tests that use solc and Ganache to ensure expected pointer changes occur over the lifetime of an actual transaction
... and expose this with a <CodeListing /> component that allows source lookup and manipulation via ts-morph library
