Aria – AI 코드 생성을 위한 전용 프로그래밍 언어

A new kind of programming language Code that costs 90% less to generate. Aria is the first programming language designed from the ground up for AI code generation. Every syntax decision minimizes tokens. Every feature eliminates boilerplate. The result: your AI writes better code, faster, at a fraction of the cost. curl -sSL https://aria-lang.com/install.sh | sh Why does this matter? AI code generation is expensive Every token your AI generates costs money. Go needs ~15 tokens per error check. Rust needs ~8. Aria needs 1. Across a full application, that's thousands of dollars in savings. Boilerplate causes bugs When an AI generates the same if err != nil pattern hundreds of times, mistakes creep in. Aria's ? operator makes error handling a single character — no pattern to get wrong. The compiler is the safety net Exhaustive pattern matching, typed errors, effect tracking, no null, no implicit conversions. The compiler catches what the AI misses — before it ever runs. Language Features Every feature exists for a reason: less tokens, more safety, zero ambiguity. One-Token Error Handling Propagate errors with a single ? . Context is injected automatically. No wrapping, no boilerplate. fn loadConfig(path: str) -> Config ! IoError { content := io.readFile(path)? json.decode[Config](content)? } Pipeline Operator Chain operations left-to-right. Reads like intent, not nested calls. result := rawData |> parseJson[Config]? |> validate? |> transform |> json.encode? Expression-Oriented Everything returns a value. No temporary variables, no mutation needed. grade := if score >= 90 { "A" } else if score >= 80 { "B" } else { "F" } area := match shape { Circle{r} => 3.14159 * r * r Rect{w, h} => w * h Point => 0.0 } Sum Types & Exhaustive Matching Define every possible state. The compiler rejects incomplete handling — no missing cases, ever. type Shape = | Circle { radius: f64 } | Rect { w: f64, h: f64 } | Point // Compiler error if you miss a variant Effect Tracking Function signatures declare what side effects they perform. Pure functions stay pure. The compiler enforces it. // Pure — safe to cache and parallelize fn total(items: [Item]) -> f64 = items.map(.price).sum() // Declares I/O + filesystem effects fn readConfig(path: str) -> Config ! IoError with [Io, Fs] { ... } Structured Concurrency Tasks cannot leak. Errors propagate. All spawned work completes before the scope exits. scope { a := spawn fetchUsers() b := spawn fetchOrders() } // Both done. No leaks. No forgotten joins. // Channels ch := chan[str]() spawn fn() { ch.send("hello") }() msg := ch.recv() Coming soon select for multi-channel multiplexing is parsed but not yet runtime-complete. Unambiguous Generics Square brackets for type parameters. No turbofish. a U) -> [U] = [f(x) for x in list] fn largest[T: Ord](items: [T]) -> T? { ... } No Null. No Exceptions. Option[T] for absence. Result[T, E] for errors. Both checked at compile time. Shortcuts: T? and T ! E . // T? is sugar for Option[T] fn find(id: i64) -> User? { ... } name := user?.address?.city ?? "unknown" Opt-In Memory Control GC by default — zero annotations needed. Drop to manual when performance demands it. Memory annotations are parsed but not yet wired to their runtime strategies. x := Thing{...} // GC, invisible buffer := @stack Buffer.withCapacity(4096) parsed := @arena(a) parseRequest(req)? conn := pool.get() defer pool.put(conn) One-Word Imports The standard library is designed for the 90% case. One import, one function call. use io, net, json, db, time, crypto content := io.readFile("config.json")? resp := net.get("https://api.example.com")? data := json.decode[Config](resp.body)? Aria vs. The Alternatives Same task. Dramatically different token counts. Error handling across 5 fallible calls result1, err := doStep1() if err != nil { return fmt.Errorf("step1: %w", err) } result2, err := doStep2(result1) if err != nil { return fmt.Errorf("step2: %w", err) } result3, err := doStep3(result2) if err != nil { return fmt.Errorf("step3: %w", err) } result4, err := doStep4(result3) if err != nil { return fmt.Errorf("step4: %w", err) } result5, err := doStep5(result4) if err != nil { return fmt.Errorf("step5: %w", err) } let result1 = do_step1() .context("step1")?; let result2 = do_step2(result1) .context("step2")?; let result3 = do_step3(result2) .context("step3")?; let result4 = do_step4(result3) .context("step4")?; let result5 = do_step5(result4) .context("step5")?; result1 := doStep1()? result2 := doStep2(result1)? result3 := doStep3(result2)? result4 := doStep4(result3)? result5 := doStep5(result4)? // Context injected automatically Read a file to string f, err := os.Open("config.json") if err != nil { return err } defer f.Close() bytes, err := io.ReadAll(f) if err != nil { return err } content := string(bytes) let content = std::fs::read_to_string( "config.json" )?; std::ifstream file("config.json"); if (!file.is_open()) { throw std::runtime_error("..."); } std::string content( (std::istreambuf
