Building Languages Using Kotlin
summary
Claim: Kotlin plus ANTLR and concise language features let a single engineer build a parser, model, validator, interpreter and a simple editor in about ≈1000 lines of code. Uses ANTLR for lexer/parser, Kotlin data classes and extension functions for mapping and tree validation, ASM for JVM bytecode and a small KLLVM layer for native code. Notes: interpreter is simplest, JVM compiler is 2–3× harder, LLVM about 50% more, and a simulator + editor (with autocomplete/scoping work) materially improves usability.
