# RIINA
**Formally verified programming language.**
***If it compiles, it's secure.***
Security properties are not tested, not assumed — they are *mathematically proven* at compile time.

## AI-Native Language
RIINA is the world's first programming language that is both **formally verified** and **AI-native**. Every security guarantee has a machine-checked mathematical proof, and the language is designed from the ground up for AI agents to read, write, and reason about.
**AI-Writability Score: 9.7/10** -- Consistent Bahasa Melayu keywords, minimal syntax, strong types, and deterministic compilation make RIINA one of the most AI-friendly languages ever designed.
AI agents: See [llms.txt](llms.txt) for a machine-readable language reference.
### For AI Agents
RIINA provides first-class support for AI-assisted development:
- **Programmatic compilation:** `riinac check --json --stdin` accepts source on stdin and returns structured JSON diagnostics
- **Full machine reference:** [llms-full.txt](llms-full.txt) contains the complete language specification, type system, and effect system in a single file
- **Code patterns:** [07_EXAMPLES/](07_EXAMPLES/) contains 130+ annotated examples across 10 categories (security, effects, compliance, design patterns, FFI, and more)
- **IDE integration:** [.cursorrules](.cursorrules) and [.clinerules](.clinerules) provide pre-configured rules for Cursor and Cline; [.github/copilot-instructions.md](.github/copilot-instructions.md) provides GitHub Copilot context
---
## What is RIINA?
RIINA is a programming language where **every security guarantee has a machine-checked mathematical proof**. If your program compiles, it is secure — not by convention, not by best practice, but by proof.
Most languages ask you to *trust* that your code is secure. RIINA asks you to *verify* it.
| What RIINA proves at compile time | How |
|---|---|
| No information leaks between security levels | Non-interference theorem (Coq) |
| No unauthorized effect execution | Effect gate algebra (Coq) |
| Type safety (no runtime type errors) | Progress + Preservation theorems (Coq) |
| No secret data in public outputs | Declassification policy proofs (Coq) |
| Termination of all pure computations | Strong normalization proofs (Coq) |
| Memory safety without garbage collection | Separation logic proofs (Coq) |
These are not aspirational goals — they are proven theorems that compile today.
---
## Why RIINA?
**If you write software where security matters, RIINA is for you.**
- Building a payments system? RIINA *proves* cardholder data never leaks.
- Building healthcare software? RIINA *proves* patient records stay confidential.
- Building infrastructure? RIINA *proves* no unauthorized side effects execute.
- Building anything? RIINA gives you **zero-trust guarantees from the compiler itself**.
RIINA doesn't care what industry you're in. If you care about getting security right — provably, permanently, without hoping your tests caught everything — RIINA is the tool.
### What makes RIINA different from every other language

| Effect tracking | Proven (effect algebra) | None | Monads (no proof) | None |
| Type safety | Proven (Progress + Preservation) | Tested | Tested | Proven (SPARK subset) |

## Quick Start
### Install
```bash
git clone https://github.com/ib823/riina.git
cd riina/03_PROTO
cargo build --release
```
The compiler binary is `riinac`. Zero external dependencies — everything is built from source.
**Alternative install methods:**
```bash
# Docker (build from source)
docker build -t riina .
docker run --rm riina check myfile.rii
# Nix
nix run github:ib823/riina
# Portable installer (builds from source)
bash scripts/install.sh
```
### Hello World
Create `hello.rii`:
```riina
// Hello World in RIINA
// Keywords are in Bahasa Melayu (Malaysian Malay)
fungsi utama() -> Teks kesan IO {
biar mesej = "Selamat datang ke RIINA!";
cetakln(mesej);
pulang mesej;
}
```
```bash
riinac check hello.rii # Type-check and verify
riinac run hello.rii # Run directly
riinac build hello.rii # Compile to native binary via C
```
### Security in Action
```riina
// RIINA prevents information leaks at compile time
fungsi proses_pembayaran(kad: Rahsia, jumlah: Nombor) -> Teks kesan Crypto {
// 'kad' is Secret — the compiler PROVES it never reaches public output
biar hash = sha256(kad); // OK: crypto on secret data
biar resit = "Jumlah: " + ke_teks(jumlah); // OK: amount is public
// cetakln(kad); // COMPILE ERROR: secret data in IO effect
// pulang kad; // COMPILE ERROR: secret in public return
pulang resit; // OK: only public data returned
}
```
This is not a runtime check. This is not a linter warning. The **compiler proves** at the type level that secret data cannot flow to public outputs. If it compiles, the guarantee holds.
### Effect System
```riina
// Every side effect is tracked and proven safe
fungsi baca_config(laluan: Teks) -> Teks kesan IO {
biar kandungan = fail_baca(laluan);
pulang kandungan;
}
fungsi kira_cukai(pendapatan: Nombor) -> Nombor kesan Bersih {
// This function is PROVEN pure — no IO, no network, no side effects
// The compiler enforces this, not the programmer
pulang pendapatan * 0.06;
}
// Dependencies cannot escalate effects without explicit permission
// A crypto library cannot secretly open network connections
```
---
## Bahasa Melayu Syntax
RIINA uses **Bahasa Melayu** (Malaysian Malay) keywords — the first systems programming language with native Southeast Asian syntax.
| RIINA | English | Example |
|-------|---------|---------|
| `fungsi` | fn | `fungsi tambah(x: Nombor) -> Nombor` |
| `biar` | let | `biar nama = "Ahmad";` |
| `kalau` | if | `kalau x > 0 { ... }` |
| `lain` | else | `lain { ... }` |
| `untuk` | for | `untuk x dalam senarai { ... }` |
| `selagi` | while | `selagi aktif { ... }` |
| `pulang` | return | `pulang hasil;` |
| `padan` | match | `padan nilai { ... }` |
| `rahsia` | secret | `biar kunci: Rahsia` |
| `dedah` | declassify | `dedah(nilai)` |
| `kesan` | effect | `kesan IO` |
| `bersih` | pure | `kesan Bersih` |
| `betul` / `salah` | true / false | Boolean values |
| `ubah` | mut | `biar ubah x = 0;` |
You don't need to speak Malay to use RIINA. The keywords are consistent, short, and learnable in an afternoon. But if you *do* speak Malay, this is the first language that speaks your language.

---
## Security & Verification
RIINA uses **compiler-integrated verification** — no external CI/CD. Verification lives inside the compiler.
```bash
riinac verify --fast # Tests + clippy (runs on every commit via pre-commit hook)
riinac verify --full # + Coq admits/axioms scan (runs on every push via pre-push hook)
```
**Git hooks** enforce verification automatically:
- **Pre-commit:** `riinac verify --fast` blocks commits with failing tests
- **Pre-push:** `riinac verify --full` + GPG signature check + secret detection + Trojan source scan
Install hooks: `./00_SETUP/scripts/install_hooks.sh`
**Deep verification** (manual, 7 levels): `bash 05_TOOLING/scripts/verify.sh [0-6]`
Verification is enforced automatically via git hooks installed by `./00_SETUP/scripts/install_hooks.sh`.

## FAQ
**Is RIINA production-ready?**
The compiler, proofs, and toolchain are functional. Phases 1-6 (compiler, stdlib, proofs, developer tools, ecosystem, adoption) are complete. Phase 7 (Platform Universality — WASM, mobile backends) is in progress. Phase 8 (self-hosting, hardware verification) is the long-term vision. You can write, compile, and run RIINA programs today — via source build, Docker, or Nix.
**Do I need to know Bahasa Melayu?**
No. The keywords are short and consistent — `fungsi` (function), `biar` (let), `kalau` (if), `pulang` (return). You'll learn them in minutes. A [cheatsheet](07_EXAMPLES/06_ai_context/RIINA_CHEATSHEET.md) is included.
**Do I need to understand Coq or formal verification?**
No. The proofs run at compile time automatically. You write normal code; the compiler does the proving. The Coq proofs are there for auditability — you benefit from them without reading them.
**Why zero external dependencies?**
Trust. Every line of RIINA — compiler, crypto, standard library — is auditable from source. No supply chain attacks. No dependency confusion. No left-pad incidents.
**Why Bahasa Melayu?**
RIINA developed by Malaysians for the world. Programming languages have been English-only for 70 years. RIINA proves that formal verification and native-language syntax are not mutually exclusive. If a language can be proven correct, it can be proven correct in any language.
**How does RIINA compare to SPARK/Ada?**
SPARK proves absence of runtime errors (overflow, division by zero) for a subset of Ada. RIINA proves information flow security (non-interference), effect safety, declassification correctness, and more — for the entire language. Both are formally verified; RIINA's scope is broader.
