The Secret to Perfect Match DSL Revealed by Experts

Описание: Want a practical trick for making an LLM-focused DSL predictable and robust? In this clip I explain why matching DSL entities by array index (not by name or ad-hoc IDs) can make updates and state reconciliation far simpler.

You'll hear the tradeoffs — why matching by name would force names to be immutable, why trying to invent a separate stable key in YAML defeats the goal of simplicity, and how matching by index keeps developer ergonomics high while pushing complexity into a state file the CLI manages. This is a small design choice that removes lots of edge-case bugs and surprising behavior when users rename things or reorder files.

If you build developer-facing DSLs or infra tooling, this design pattern is something you should seriously consider. Want the full system design and example YAML/JSON state I used? Comment below with "state" and I'll post the example in the next video. If you found this useful, like, share and subscribe for more system-design-for-developers content.
