Amanda Laucher talks about Oslo and its tools, Intellipad, M.exe – the M Compiler, MB.exe – MGrammar Compiler, and how they can be used to create a DSL. She demonstrates the creation of a demo DSL in Oslo.

Josh Phillips(PM), Niklas Gustafsson(Architect), and Artur Laksberg(Developer) of the Parallel Computing Platform Team spend some time with me to discuss a managed (.NET-based) DSL (Domain Specific Language) for concurrent programming, Maestro. Maestro incorporates well-entrenched language patterns (imperative, OO, C style syntax, etc) and language constructs (channels, agents, domains) in a compelling way to make concurrent composition more accessible and familiar to the legions of sequential code composers.  Here we dig into the architecture and design of the Maestro language and compiler as well as …

The “Oslo” modeling language can define schemas and transformations over arbitrary text formats. This session shows you how to build your own Domain Specific Language using the “Oslo” SDK and how to apply your DSL to create an interactive text editing experience.
