Virtual Domain Specific Languages via Embedded Projectional Editing

Explore a 28-minute conference talk from GPCE 2023 that introduces a novel approach to implementing Domain Specific Languages (DSLs) through embedded projectional editing. Discover how this method bridges the gap between internal and external DSLs by representing GPL subsets as GUI widgets in a hybrid editor. Learn about the advantages of this 'virtual' DSL approach, including seamless integration with general-purpose languages, reduced development overhead, and compatibility with mainstream programming languages like Python and JavaScript. Gain insights into pattern matching techniques, dynamic widget rendering, and an innovative method for generating patterns from example pairs. Access a live demo and source code to see the system in action across various domain use cases. Presented by Niklas Korz and Artur Andrzejak, this talk offers valuable perspectives on advancing DSL implementation and enhancing programming language integration.
