Unlike general-purpose languages (Python, JavaScript, Go), Vfly Script is intentionally restricted and optimized for — often used in CI/CD pipelines, serverless functions, API gateways, and IoT edge devices. 2. Core Characteristics | Feature | Description | |-----------------------|-----------------------------------------------------------------------------| | Interpreted | No compilation step; executes directly from source via a small VM. | | Memory-safe | Automatic garbage collection with bounded heap (no unbounded allocation). | | Concurrency Model | Actor-based (like Erlang) or async/await (configurable). | | Type System | Dynamic with optional gradual typing ( .vfly files support type hints). | | Standard Library | Minimal: HTTP client, file I/O, JSON, regex, timers, process spawning. | | Embeddable | Can be embedded into Go, Rust, or C++ applications as a scripting engine. | 3. Language Syntax (Example) // Vfly Script sample: HTTP request + JSON processing import http import json
return total
// Entry point (optional, runs automatically) task main() result = fetch_and_sum("https://api.example.com/numbers") println("Sum: (result)") Vfly Script -Fly Script---
If your current scripts in Bash, Python, or JavaScript feel too heavy, fragile, or slow to start, Vfly Script offers a compelling, purpose-built alternative. Note: As of early 2026, Vfly Script is an emerging technology. Always refer to the official documentation for the latest syntax, APIs, and stability guarantees. | | Memory-safe | Automatic garbage collection with
vfly run script.vfly --allow-net=api.example.com:443 --allow-read=/tmp Logs are automatically emitted as JSON with trace IDs, making them compatible with Loki, DataDog, or Splunk. | | Standard Library | Minimal: HTTP client,
