Han (한) Programming Language

Han is a statically-typed, compiled programming language where every keyword is written in Korean (Hangul). It compiles to native binaries through LLVM IR and includes a tree-walking interpreter for instant execution.

Quick Example

함수 인사(이름: 문자열) {
    출력("${이름}님 안녕하세요")
}

인사("세계")

Output: 세계님 안녕하세요

Key Features

• Korean keywords — 함수, 만약, 이면, 반복, 변수
• Korean word order — 만약 조건 이면 { }, 조건 동안 { }
• String interpolation — "${expr}" auto-desugars to 형식()
• Korean logical operators — 그리고, 또는
• Dual execution — interpreter (hgl interpret) and compiler (hgl build)
• Tooling — hgl check, hgl init, VS Code extension, and LSP support
• Learning path — examples/교육_*.hgl includes 10 SOV-first educational programs
• Arrays, structs, enums, tuples, closures, pattern matching
• Error handling — 시도 / 처리 with Elm-style source-context errors
• File I/O, format strings, module imports

How It Works

Source (.hgl) → Lexer → Parser → AST → Interpreter (direct execution)
                                     → CodeGen → LLVM IR → clang → Binary
