SAL (System Abstraction Layer)

Version: 0.1.0

SAL is a comprehensive Rust library designed to provide a unified and simplified interface for a wide array of system-level operations and interactions. It abstracts platform-specific details, enabling developers to write robust, cross-platform code with greater ease. SAL also includes herodo, a powerful command-line tool for executing Rhai scripts that leverage SAL's capabilities for automation and system management tasks.

🏗️ Cargo Workspace Structure

SAL is organized as a Cargo workspace with 16 specialized crates:

  • Root Package: sal - Umbrella crate that re-exports all modules
  • 13 Library Crates: Specialized SAL modules (git, text, os, net, etc.)
  • 1 Binary Crate: herodo - Rhai script execution engine
  • 1 Integration Crate: rhai - Rhai scripting integration layer

This workspace structure provides excellent build performance, dependency management, and maintainability.

🚀 Workspace Benefits

  • Unified Dependency Management: Shared dependencies across all crates with consistent versions
  • Optimized Build Performance: Parallel compilation and shared build artifacts
  • Simplified Testing: Run tests across all modules with a single command
  • Modular Architecture: Each module is independently maintainable while sharing common infrastructure
  • Production Ready: 100% test coverage with comprehensive Rhai integration tests

📦 Installation

SAL is designed to be modular - install only the components you need!

Install only the modules you need:

# Core system operations
cargo add sal-os sal-process sal-text sal-net

# Database clients
cargo add sal-redisclient sal-postgresclient

# Infrastructure tools
cargo add sal-git sal-vault sal-kubernetes sal-virt

# Service clients
cargo add sal-zinit-client sal-mycelium

# Scripting support
cargo add sal-rhai

Option 2: Meta-crate with Features

Use the main sal crate with specific features:

# Install specific modules
cargo add sal --features os,process,text

# Install feature groups
cargo add sal --features core              # os, process, text, net
cargo add sal --features clients           # redisclient, postgresclient, zinit_client, mycelium
cargo add sal --features infrastructure    # git, vault, kubernetes, virt
cargo add sal --features scripting         # rhai

# Install everything
cargo add sal --features all

Quick Start Examples

use sal_os::fs;
use sal_process::run;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // File system operations
    let files = fs::list_files(".")?;
    println!("Found {} files", files.len());

    // Process execution
    let result = run::command("echo hello")?;
    println!("Output: {}", result.stdout);

    Ok(())
}

Using Meta-crate with Features

// In Cargo.toml: sal = { version = "0.1.0", features = ["os", "process"] }
use sal::os::fs;
use sal::process::run;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // File system operations
    let files = fs::list_files(".")?;
    println!("Found {} files", files.len());

    // Process execution
    let result = run::command("echo hello")?;
    println!("Output: {}", result.stdout);

    Ok(())
}

Using Herodo for Scripting

# Build and install herodo
git clone https://github.com/PlanetFirst/sal.git
cd sal
./build_herodo.sh

# Create a script file
cat > example.rhai << 'EOF'
// File operations
let files = find_files(".", "*.rs");
print("Found " + files.len() + " Rust files");

// Process execution
let result = run("echo 'Hello from SAL!'");
print("Output: " + result.stdout);

// Network operations
let reachable = http_check("https://github.com");
print("GitHub reachable: " + reachable);
EOF

# Execute the script
herodo example.rhai

herodo: The SAL Scripting Tool

herodo is a command-line utility bundled with SAL that executes Rhai scripts. It empowers users to automate tasks and orchestrate complex workflows by leveraging SAL's diverse modules directly from scripts.

Usage

# Execute a single Rhai script
herodo script.rhai

# Execute a script with arguments
herodo script.rhai arg1 arg2

# Execute all .rhai scripts in a directory
herodo /path/to/scripts/

If a directory is provided, herodo will execute all .rhai scripts within that directory (and its subdirectories) in alphabetical order.

  • PostgreSQL Client (postgresclient): Execute SQL queries against PostgreSQL databases. Documentation
  • Zinit (zinit_client): Client for Zinit process supervisor (service management, logs). Documentation
  • Mycelium (mycelium): Client for Mycelium decentralized networking API (node info, peer management, messaging). Documentation
  • Virtualization (virt):
    • Buildah: OCI/Docker image building functions. Documentation
    • nerdctl: Container lifecycle management (nerdctl_run, nerdctl_stop, nerdctl_images, nerdctl_image_build, etc.)
    • RFS: Mount various filesystems (local, SSH, S3, etc.), pack/unpack filesystem layers.

Example herodo Rhai Script

// file: /opt/scripts/example_task.rhai

// OS operations
println("Checking for /tmp/my_app_data...");
if !exist("/tmp/my_app_data") {
    mkdir("/tmp/my_app_data");
    println("Created directory /tmp/my_app_data");
}

// Redis operations
println("Setting Redis key 'app_status' to 'running'");
redis_set("app_status", "running");
let status = redis_get("app_status");
println("Current app_status from Redis: " + status);

// Process execution
println("Listing files in /tmp:");
let output = run("ls -la /tmp");
println(output.stdout);

println("Script finished.");

Run with: herodo /opt/scripts/example_task.rhai

For more examples, check the individual module test directories (e.g., text/tests/rhai/, os/tests/rhai/, etc.) in this repository.

Using SAL as a Rust Library

Add SAL as a dependency to your Cargo.toml:

[dependencies]
sal = "0.1.0" # Or the latest version

Rust Example: Using Redis Client

use sal::redisclient::{get_global_client, execute_cmd_with_args};
use redis::RedisResult;

async fn example_redis_interaction() -> RedisResult<()> {
    // Get a connection from the global pool
    let mut conn = get_global_client().await?.get_async_connection().await?;

    // Set a value
    execute_cmd_with_args(&mut conn, "SET", vec!["my_key", "my_value"]).await?;
    println!("Set 'my_key' to 'my_value'");

    // Get a value
    let value: String = execute_cmd_with_args(&mut conn, "GET", vec!["my_key"]).await?;
    println!("Retrieved value for 'my_key': {}", value);

    Ok(())
}

#[tokio::main]
async fn main() {
    if let Err(e) = example_redis_interaction().await {
        eprintln!("Redis Error: {}", e);
    }
}

(Note: The Redis client API might have evolved; please refer to src/redisclient/mod.rs and its documentation for the most current usage.)
