+# SAL Network Package (`sal-net`)
+
+Network connectivity utilities for TCP, HTTP, and SSH operations.
+
+## Installation
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+sal-net = "0.1.0"
+```
+
+## Overview
+
+The `sal-net` package provides a comprehensive set of network connectivity tools for the SAL (System Abstraction Layer) ecosystem. It includes utilities for TCP port checking, HTTP/HTTPS connectivity testing, and SSH command execution.
+
+## Features
+
+### TCP Connectivity
+- **Port checking**: Test if specific TCP ports are open
+- **Multi-port checking**: Test multiple ports simultaneously  
+- **ICMP ping**: Test host reachability using ping
+- **Configurable timeouts**: Customize connection timeout values
+
+### HTTP/HTTPS Connectivity
+- **URL reachability**: Test if URLs are accessible
+- **Status code checking**: Get HTTP status codes from URLs
+- **Content fetching**: Download content from URLs
+- **Status verification**: Verify URLs return expected status codes
+
+### SSH Operations
+- **Command execution**: Run commands on remote hosts via SSH
+- **Connection testing**: Test SSH connectivity to hosts
+- **Builder pattern**: Flexible SSH connection configuration
+- **Custom authentication**: Support for identity files and custom ports
+
+## Rust API
+
+### TCP Operations
+
+```rust
+use sal_net::TcpConnector;
+use std::time::Duration;
+
+// Create a TCP connector
+let connector = TcpConnector::new();
+
+// Check if a port is open
+let is_open = connector.check_port("127.0.0.1".parse().unwrap(), 80).await?;
+
+// Check multiple ports
+let ports = vec![22, 80, 443];
+let results = connector.check_ports("example.com".parse().unwrap(), &ports).await?;
+
+// Ping a host
+let is_reachable = connector.ping("google.com").await?;
+```
+
+### HTTP Operations
+
+```rust
+use sal_net::HttpConnector;
+
+// Create an HTTP connector
+let connector = HttpConnector::new()?;
+
+// Check if a URL is reachable
+let is_reachable = connector.check_url("https://example.com").await?;
+
+// Get status code
+let status = connector.check_status("https://example.com").await?;
+
+// Fetch content
+let content = connector.get_content("https://api.example.com/data").await?;
+
+// Verify specific status
+let matches = connector.verify_status("https://example.com", reqwest::StatusCode::OK).await?;
+```
+
+### SSH Operations
+
+```rust
+use sal_net::SshConnectionBuilder;
+use std::time::Duration;
+
+// Build an SSH connection
+let connection = SshConnectionBuilder::new()
+    .host("example.com")
+    .port(22)
+    .user("username")
+    .timeout(Duration::from_secs(30))
+    .build();
+
+// Execute a command
+let (exit_code, output) = connection.execute("ls -la").await?;
+
+// Test connectivity
+let is_connected = connection.ping().await?;
+```
+
+## Rhai Integration
+
+The package provides Rhai scripting integration for network operations:
+
+### TCP Functions
+
+```rhai
+// Check if a TCP port is open
+let is_open = tcp_check("127.0.0.1", 80);
+print(`Port 80 is ${is_open ? "open" : "closed"}`);
+
+// Ping a host (cross-platform)
+let can_ping = tcp_ping("google.com");
+print(`Can ping Google: ${can_ping}`);
+```
+
+### HTTP Functions
+
+```rhai
+// Check if an HTTP URL is reachable
+let is_reachable = http_check("https://example.com");
+print(`URL is ${is_reachable ? "reachable" : "unreachable"}`);
+
+// Get HTTP status code
+let status = http_status("https://example.com");
+print(`HTTP status: ${status}`);
+```
+
+### SSH Functions
+
+```rhai
+// Execute SSH command and get exit code
+let exit_code = ssh_execute("example.com", "user", "ls -la");
+print(`SSH command exit code: ${exit_code}`);
+
+// Execute SSH command and get output
+let output = ssh_execute_output("example.com", "user", "whoami");
+print(`SSH output: ${output}`);
+
+// Test SSH connectivity
+let can_connect = ssh_ping("example.com", "user");
+print(`SSH connection: ${can_connect ? "success" : "failed"}`);
+```
+
+### Example Rhai Script
+
+```rhai
+// Network connectivity test script
+print("=== Network Connectivity Test ===");
+
+// Test TCP connectivity
+let ports = [22, 80, 443];
+for port in ports {
+    let is_open = tcp_check("example.com", port);
+    print(`Port ${port}: ${is_open ? "OPEN" : "CLOSED"}`);
+}
+
+// Test ping connectivity
+let hosts = ["google.com", "github.com", "stackoverflow.com"];
+for host in hosts {
+    let can_ping = tcp_ping(host);
+    print(`${host}: ${can_ping ? "REACHABLE" : "UNREACHABLE"}`);
+}
+
+// Test HTTP connectivity
+let urls = ["https://google.com", "https://github.com", "https://httpbin.org/status/200"];
+for url in urls {
+    let is_reachable = http_check(url);
+    let status = http_status(url);
+    print(`${url}: ${is_reachable ? "REACHABLE" : "UNREACHABLE"} (Status: ${status})`);
+}
+
+// Test SSH connectivity (requires SSH access)
+let ssh_hosts = ["example.com"];
+for host in ssh_hosts {
+    let can_connect = ssh_ping(host, "user");
+    print(`SSH ${host}: ${can_connect ? "CONNECTED" : "FAILED"}`);
+}
+```
+
+## Testing
+
+The package includes comprehensive tests:
+
+```bash
+# Run all tests
+cargo test
+
+# Run specific test suites
+cargo test --test tcp_tests
+cargo test --test http_tests  
+cargo test --test ssh_tests
+cargo test --test rhai_integration_tests
+
+# Run Rhai script tests
+cargo test --test rhai_integration_tests
+```
+
+## Dependencies
+
+- `tokio`: Async runtime for network operations
+- `reqwest`: HTTP client functionality
+- `anyhow`: Error handling
+- `rhai`: Scripting integration
+
+## Security Considerations
+
+- SSH operations use the system's SSH client for security
+- HTTP operations respect standard timeout and security settings
+- No credentials are logged or exposed in error messages
+- Network timeouts prevent hanging operations
+
+## Platform Support
+
+- **Linux**: Full support for all features
+- **macOS**: Full support for all features  
+- **Windows**: TCP and HTTP support (SSH requires SSH client installation)
+
+## Error Handling
+
+All network operations return `Result` types with meaningful error messages. Operations gracefully handle:
+
+- Network timeouts
+- Connection failures
+- Invalid hostnames/URLs
+- Authentication failures (SSH)
+- System command failures
+
+## Performance
+
+- Async operations for non-blocking network calls
+- Configurable timeouts for responsive applications
+- Efficient connection reuse where possible
+- Minimal memory footprint for network operations

+# SAL Text - Text Processing and Manipulation Utilities (`sal-text`)
+
+SAL Text provides a comprehensive collection of text processing utilities for both Rust applications and Rhai scripting environments.
+
+## Installation
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+sal-text = "0.1.0"
+```
+
+## Features
+
+- **Text Indentation**: Remove common leading whitespace (`dedent`) and add prefixes (`prefix`)
+- **String Normalization**: Sanitize strings for filenames (`name_fix`) and paths (`path_fix`)
+- **Text Replacement**: Powerful `TextReplacer` for regex and literal replacements
+- **Template Rendering**: `TemplateBuilder` using Tera engine for dynamic text generation
+
+## Rust API
+
+### Text Indentation
+
+```rust
+use sal_text::{dedent, prefix};
+
+// Remove common indentation
+let indented = "    line 1\n    line 2\n        line 3";
+let dedented = dedent(indented);
+assert_eq!(dedented, "line 1\nline 2\n    line 3");
+
+// Add prefix to each line
+let text = "line 1\nline 2";
+let prefixed = prefix(text, "> ");
+assert_eq!(prefixed, "> line 1\n> line 2");
+```
+
+### String Normalization
+
+```rust
+use sal_text::{name_fix, path_fix};
+
+// Sanitize filename
+let unsafe_name = "User's File [Draft].txt";
+let safe_name = name_fix(unsafe_name);
+assert_eq!(safe_name, "user_s_file_draft_.txt");
+
+// Sanitize path (preserves directory structure)
+let unsafe_path = "/path/to/User's File.txt";
+let safe_path = path_fix(unsafe_path);
+assert_eq!(safe_path, "/path/to/user_s_file.txt");
+```
+
+### Text Replacement
+
+```rust
+use sal_text::TextReplacer;
+
+// Simple literal replacement
+let replacer = TextReplacer::builder()
+    .pattern("hello")
+    .replacement("hi")
+    .build()
+    .expect("Failed to build replacer");
+
+let result = replacer.replace("hello world, hello universe");
+assert_eq!(result, "hi world, hi universe");
+
+// Regex replacement
+let replacer = TextReplacer::builder()
+    .pattern(r"\d+")
+    .replacement("NUMBER")
+    .regex(true)
+    .build()
+    .expect("Failed to build replacer");
+
+let result = replacer.replace("There are 123 items");
+assert_eq!(result, "There are NUMBER items");
+
+// Chained operations
+let replacer = TextReplacer::builder()
+    .pattern("world")
+    .replacement("universe")
+    .and()
+    .pattern(r"\d+")
+    .replacement("NUMBER")
+    .regex(true)
+    .build()
+    .expect("Failed to build replacer");
+```
+
+### Template Rendering
+
+```rust
+use sal_text::TemplateBuilder;
+
+let result = TemplateBuilder::open("template.txt")
+    .expect("Failed to open template")
+    .add_var("name", "World")
+    .add_var("count", 42)
+    .render()
+    .expect("Failed to render template");
+```
+
+## Rhai Scripting
+
+All functionality is available in Rhai scripts when using `herodo`:
+
+```rhai
+// Text indentation
+let dedented = dedent("    hello\n    world");
+let prefixed = prefix("line1\nline2", "> ");
+
+// String normalization
+let safe_name = name_fix("User's File [Draft].txt");
+let safe_path = path_fix("/path/to/User's File.txt");
+
+// Text replacement
+let builder = text_replacer_new();
+builder = pattern(builder, "hello");
+builder = replacement(builder, "hi");
+builder = regex(builder, false);
+
+let replacer = build(builder);
+let result = replace(replacer, "hello world");
+
+// Template rendering
+let template = template_builder_open("template.txt");
+template = add_var(template, "name", "World");
+let result = render(template);
+```
+
+## Testing
+
+Run the comprehensive test suite:
+
+```bash
+# Unit tests
+cargo test
+
+# Rhai integration tests
+cargo run --bin herodo tests/rhai/run_all_tests.rhai
+```
+
+## Dependencies
+
+- `regex`: For regex-based text replacement
+- `tera`: For template rendering
+- `serde`: For template variable serialization
+- `rhai`: For Rhai scripting integration

+//! SAL Text - Text processing and manipulation utilities
+//!
+//! This crate provides a comprehensive collection of text processing utilities including:
+//! - **Text indentation**: Remove common leading whitespace (`dedent`) and add prefixes (`prefix`)
+//! - **String normalization**: Sanitize strings for filenames (`name_fix`) and paths (`path_fix`)
+//! - **Text replacement**: Powerful `TextReplacer` for regex and literal replacements
+//! - **Template rendering**: `TemplateBuilder` using Tera engine for dynamic text generation
+//!
+//! All functionality is available in both Rust and Rhai scripting environments.
+//!
+//! # Examples
+//!
+//! ## Text Indentation
+//!
+//! ```rust
+//! use sal_text::dedent;
+//!
+//! let indented = "    line 1\n    line 2\n        line 3";
+//! let dedented = dedent(indented);
+//! assert_eq!(dedented, "line 1\nline 2\n    line 3");
+//! ```
+//!
+//! ## String Normalization
+//!
+//! ```rust
+//! use sal_text::name_fix;
+//!
+//! let unsafe_name = "User's File [Draft].txt";
+//! let safe_name = name_fix(unsafe_name);
+//! assert_eq!(safe_name, "user_s_file_draft_.txt");
+//! ```
+//!
+//! ## Text Replacement
+//!
+//! ```rust
+//! use sal_text::TextReplacer;
+//!
+//! let replacer = TextReplacer::builder()
+//!     .pattern(r"\d+")
+//!     .replacement("NUMBER")
+//!     .regex(true)
+//!     .build()
+//!     .expect("Failed to build replacer");
+//!
+//! let result = replacer.replace("There are 123 items");
+//! assert_eq!(result, "There are NUMBER items");
+//! ```
