- Language Workbenches are tools designed to support Language Oriented Programming (LOP), a development style centered around using Domain Specific Languages (DSLs).
- Examples of Language Workbenches include Intentional Software, JetBrains's Meta Programming System (MPS), and Microsoft's Software Factories.
- LOP involves building software systems using multiple DSLs, which can be either internal (embedded within a host language) or external (separate languages).
- External DSLs offer flexibility in syntax but require building parsers and lack integration with host language tooling.
- Internal DSLs leverage the host language's syntax and tooling but are constrained by the host language's capabilities.
- Language Workbenches aim to combine the benefits of both approaches by providing tools to define DSLs with integrated editors and generators, eliminating the need for separate parsers.
- Key features of Language Workbenches include persistent abstract representations (semantic models), projectional editors, and the ability to handle incomplete or contradictory information.
- Challenges include vendor lock-in, version control for semantic models, and the need for evolutionary design to allow DSLs and their usage to co-evolve.
- Potential benefits include improved programmer productivity and better collaboration with domain experts, though the latter remains a significant challenge.
- The future of DSLs may involve more sophisticated, example-centric, and interactive editing environments, moving beyond traditional textual or graphical representations.
