Rule Compiler · YARA Forge

📚 What You'll Learn Here

Compiling YARA rules to binary format (`yarac`) for faster scanning and easier distribution.

1. Basic Compilation — `yarac source.yar compiled.bin`
2. Multiple Source Files — `yarac rule1.yar rule2.yar rules.bin`
3. Compiler Options — `-w` (warnings), `-d` (external vars), `-p` (fail on warnings)
4. Performance Benefits — Binary rules vs source parsing speed
5. Error Handling — Debugging compilation errors
6. Distribution — Sharing compiled rules without source
7. Version Compatibility — Matching compiled rules to YARA version
8. Decompilation — Reverse engineering compiled rules (limits)

🛠️ WEB COMPILER (Coming Soon)
Compile rules online, download `.yar` or `.bin` formats.

⚔️ Practice Challenge

Take a rule file with 20+ rules. Compile it with `yarac` and compare scan time vs source. What's the difference?
