Could you build this?
Partial A toy interpreter or basic domain-specific language can be vibe-coded, but designing and implementing a robust custom programming language with a lexer, parser, type checker, or bytecode virtual machine requires compiler fundamentals.
What it would actually take: Developing an actual programming language requires formal grammar design, lexing and parsing (using tools like ANTLR or hand-rolled recursive descent), AST generation, scope resolution, type checking, and either an AST walker or an LLVM/bytecode compiler backend. Solid understanding of programming language theory, memory layout, and runtime environments is essential.
Discussion
20 comments analyzed.
Competitors mentioned: Cucumber (natural language DSLs), IntentCode, FIM (fill in the middle) with comments
Concerns raised: Non-deterministic LLM outputs create different bugs on different machines, Unclear value proposition and problem being solved, Safety and interface communication issues between code blocks, Not suitable for production due to LLM non-determinism, Relies on unconstrained AI outputs without formal semantic checks
Feature requests: Add playground site link in repo for testing without installation, Better documentation explaining the problem this solves, Language-agnostic pidgin syntax using whitespace and indentation
