please refactor each of the objects in the the chosen folder to use builder paradigm, see below for an example
we always start from root object, each file e.g. product.rs corresponds to a root object, the rootobject is what is stored in the DB, the rest are sub objects which are children of the root object
---
### ✅ Step 1: Define your struct
```rust
#[derive(Debug)]
pub enum ProductType {
Service,
// Other variants...
}
#[derive(Debug)]
pub enum ProductStatus {
Available,
Unavailable,
// Other variants...
}
#[derive(Debug)]
pub struct Product {
id: u32,
name: String,
description: String,
price: f64,
product_type: ProductType,
category: String,
status: ProductStatus,
max_amount: u32,
validity_days: u32,
}
```
---
### ✅ Step 2: Create a builder
```rust
pub struct ProductBuilder {
id: Option<u32>,
name: Option<String>,
description: Option<String>,
price: Option<f64>,
product_type: Option<ProductType>,
category: Option<String>,
status: Option<ProductStatus>,
max_amount: Option<u32>,
validity_days: Option<u32>,
}
impl ProductBuilder {
pub fn new() -> Self {
Self {
id: None,
name: None,
description: None,
price: None,
product_type: None,
category: None,
status: None,
max_amount: None,
validity_days: None,
}
}
pub fn id(mut self, id: u32) -> Self {
self.id = Some(id);
self
}
pub fn name<S: Into<String>>(mut self, name: S) -> Self {
self.name = Some(name.into());
self
}
pub fn description<S: Into<String>>(mut self, description: S) -> Self {
self.description = Some(description.into());
self
}
pub fn price(mut self, price: f64) -> Self {
self.price = Some(price);
self
}
pub fn product_type(mut self, product_type: ProductType) -> Self {
self.product_type = Some(product_type);
self
}
pub fn category<S: Into<String>>(mut self, category: S) -> Self {
self.category = Some(category.into());
self
}
pub fn status(mut self, status: ProductStatus) -> Self {
self.status = Some(status);
self
}
pub fn max_amount(mut self, max_amount: u32) -> Self {
self.max_amount = Some(max_amount);
self
}
pub fn validity_days(mut self, validity_days: u32) -> Self {
self.validity_days = Some(validity_days);
self
}
pub fn build(self) -> Result<Product, &'static str> {
Ok(Product {
id: self.id.ok_or("id is required")?,
name: self.name.ok_or("name is required")?,
description: self.description.ok_or("description is required")?,
price: self.price.ok_or("price is required")?,
product_type: self.product_type.ok_or("type is required")?,
category: self.category.ok_or("category is required")?,
status: self.status.ok_or("status is required")?,
max_amount: self.max_amount.ok_or("max_amount is required")?,
validity_days: self.validity_days.ok_or("validity_days is required")?,
})
}
}
```
---
### ✅ Step 3: Use it like this
```rust
let product = ProductBuilder::new()
.id(1)
.name("Premium Service")
.description("Our premium service offering")
.price(99.99)
.product_type(ProductType::Service)
.category("Services")
.status(ProductStatus::Available)
.max_amount(100)
.validity_days(30)
.build()
.expect("Failed to build product");
```
---
This way:
- You don’t need to remember the order of parameters.
- You get readable, self-documenting code.
- It’s easier to provide defaults or optional values if you want later.
Want help generating this automatically via a macro or just want it shorter? I can show you a derive macro to do that too.

## Introduction
Rhai is an embedded scripting language for Rust that allows you to expose Rust functions to scripts and vice versa. This document focuses on the best practices for wrapping Rust functions so they can be called from Rhai scripts, with special attention to handling different argument types, structs, and error conditions.
## Basic Function Registration
### Simple Function Registration
The most basic way to register a Rust function with Rhai is using the `register_fn` method:
```rust
fn add(x: i64, y: i64) -> i64 {
x + y
}
fn main() -> Result<(), Box<EvalAltResult>> {
let mut engine = Engine::new();
// Register the function with Rhai
engine.register_fn("add", add);
// Now the function can be called from Rhai scripts
let result = engine.eval::<i64>("add(40, 2)")?;
println!("Result: {}", result); // prints 42
Ok(())
}
```
### Function Naming Conventions
When registering functions, follow these naming conventions:
1. Use snake_case for function names to maintain consistency with Rhai's style
2. Choose descriptive names that clearly indicate the function's purpose
3. For functions that operate on specific types, consider prefixing with the type name (e.g., `string_length`)
## Working with Different Argument Types
### Primitive Types
Rhai supports the following primitive types that can be directly used as function arguments:
- `i64` (integer)
- `f64` (float)
- `bool` (boolean)
- `String` or `&str` (string)
- `char` (character)
- `()` (unit type)
Example:
```rust
fn calculate(num: i64, factor: f64, enabled: bool) -> f64 {
if enabled {
num as f64 * factor
} else {
0.0
}
}
engine.register_fn("calculate", calculate);
```
### Arrays and Collections
For array arguments:
```rust
fn sum_array(arr: Array) -> i64 {
arr.iter()
.filter_map(|v| v.as_int().ok())
.sum()
}
engine.register_fn("sum_array", sum_array);
```
### Optional Arguments and Function Overloading
Rhai supports function overloading, which allows you to register multiple functions with the same name but different parameter types or counts:
```rust
fn greet(name: &str) -> String {
format!("Hello, {}!", name)
}
fn greet_with_title(title: &str, name: &str) -> String {
format!("Hello, {} {}!", title, name)
}
engine.register_fn("greet", greet);
engine.register_fn("greet", greet_with_title);
// In Rhai:
// greet("World") -> "Hello, World!"
// greet("Mr.", "Smith") -> "Hello, Mr. Smith!"
```
## Passing and Working with Structs
### Registering Custom Types
To use Rust structs in Rhai, you need to register them:
#### Method 1: Using the CustomType Trait (Recommended)
```rust
#[derive(Debug, Clone, CustomType)]
#[rhai_type(extra = Self::build_extra)]
struct TestStruct {
x: i64,
}
impl TestStruct {
pub fn new() -> Self {
Self { x: 1 }
}
pub fn update(&mut self) {
self.x += 1000;
}
pub fn calculate(&mut self, data: i64) -> i64 {
self.x * data
}
fn build_extra(builder: &mut TypeBuilder<Self>) {
builder
.with_name("TestStruct")
.with_fn("new_ts", Self::new)
.with_fn("update", Self::update)
.with_fn("calc", Self::calculate);
}
}
// In your main function:
let mut engine = Engine::new();
engine.build_type::<TestStruct>();
```
#### Method 2: Manual Registration
```rust
#[derive(Debug, Clone)]
struct TestStruct {
x: i64,
}
impl TestStruct {
pub fn new() -> Self {
Self { x: 1 }
}
pub fn update(&mut self) {
self.x += 1000;
}
}
let mut engine = Engine::new();
engine
.register_type_with_name::<TestStruct>("TestStruct")
.register_fn("new_ts", TestStruct::new)
.register_fn("update", TestStruct::update);
```
### Accessing Struct Fields
By default, Rhai can access public fields of registered structs:
```rust
// In Rhai script:
let x = new_ts();
x.x = 42; // Direct field access
```
### Passing Structs as Arguments
When passing structs as arguments to functions, ensure they implement the `Clone` trait:
```rust
fn process_struct(test: TestStruct) -> i64 {
test.x * 2
}
engine.register_fn("process_struct", process_struct);
```
### Returning Structs from Functions
You can return custom structs from functions:
```rust
fn create_struct(value: i64) -> TestStruct {
TestStruct { x: value }
}
engine.register_fn("create_struct", create_struct);
```
## Error Handling
Error handling is a critical aspect of integrating Rust functions with Rhai. Proper error handling ensures that script execution fails gracefully with meaningful error messages.
### Basic Error Handling
The most basic way to handle errors is to return a `Result` type:
```rust
fn divide(a: i64, b: i64) -> Result<i64, Box<EvalAltResult>> {
if b == 0 {
// Return an error if division by zero
Err("Division by zero".into())
} else {
Ok(a / b)
}
}
engine.register_fn("divide", divide);
```
### EvalAltResult Types
Rhai provides several error types through the `EvalAltResult` enum:
```rust
use rhai::EvalAltResult;
use rhai::Position;
fn my_function() -> Result<i64, Box<EvalAltResult>> {
// Different error types
// Runtime error - general purpose error
return Err(Box::new(EvalAltResult::ErrorRuntime(
"Something went wrong".into(),
Position::NONE
)));
// Type error - when a type mismatch occurs
return Err(Box::new(EvalAltResult::ErrorMismatchOutputType(
"expected i64, got string".into(),
Position::NONE,
"i64".into()
)));
// Function not found error
return Err(Box::new(EvalAltResult::ErrorFunctionNotFound(
"function_name".into(),
Position::NONE
)));
}
```
### Custom Error Types
For more structured error handling, you can create custom error types:
```rust
use thiserror::Error;
use rhai::{EvalAltResult, Position};
#[derive(Error, Debug)]
enum MyError {
#[error("Invalid input: {0}")]
InvalidInput(String),
#[error("Calculation error: {0}")]
CalculationError(String),
#[error("Database error: {0}")]
DatabaseError(String),
}
// Convert your custom error to EvalAltResult
fn process_data(input: i64) -> Result<i64, Box<EvalAltResult>> {
// Your logic here that might return a custom error
let result = validate_input(input)
.map_err(|e| Box::new(EvalAltResult::ErrorRuntime(
format!("Validation failed: {}", e),
Position::NONE
)))?;
let processed = calculate(result)
.map_err(|e| Box::new(EvalAltResult::ErrorRuntime(
format!("Calculation failed: {}", e),
Position::NONE
)))?;
if processed < 0 {
return Err(Box::new(EvalAltResult::ErrorRuntime(
"Negative result not allowed".into(),
Position::NONE
)));
}
Ok(processed)
}
// Helper functions that return our custom error type
fn validate_input(input: i64) -> Result<i64, MyError> {
if input <= 0 {
return Err(MyError::InvalidInput("Input must be positive".into()));
}
Ok(input)
}
fn calculate(value: i64) -> Result<i64, MyError> {
if value > 1000 {
return Err(MyError::CalculationError("Value too large".into()));
}
Ok(value * 2)
}
```
### Error Propagation
When calling Rhai functions from Rust, errors are propagated through the `?` operator:
```rust
let result = engine.eval::<i64>("divide(10, 0)")?; // This will propagate the error
```
### Error Context and Position Information
For better debugging, include position information in your errors:
```rust
fn parse_config(config: &str) -> Result<Map, Box<EvalAltResult>> {
// Get the call position from the context
let pos = Position::NONE; // In a real function, you'd get this from NativeCallContext
match serde_json::from_str::<serde_json::Value>(config) {
Ok(json) => {
// Convert JSON to Rhai Map
let mut map = Map::new();
// ... conversion logic ...
Ok(map)
},
Err(e) => {
Err(Box::new(EvalAltResult::ErrorRuntime(
format!("Failed to parse config: {}", e),
pos
)))
}
}
}
```
### Best Practices for Error Handling
1. **Be Specific**: Provide clear, specific error messages that help script writers understand what went wrong
2. **Include Context**: When possible, include relevant context in error messages (e.g., variable values, expected types)
3. **Consistent Error Types**: Use consistent error types for similar issues
4. **Validate Early**: Validate inputs at the beginning of functions to fail fast
5. **Document Error Conditions**: Document possible error conditions for functions exposed to Rhai
## Returning Different Types
Properly handling return types is crucial for creating a seamless integration between Rust and Rhai. This section covers various approaches to returning different types of data from Rust functions to Rhai scripts.
### Simple Return Types
For simple return types, specify the type when registering the function:
```rust
fn get_number() -> i64 { 42 }
fn get_string() -> String { "hello".to_string() }
fn get_boolean() -> bool { true }
fn get_float() -> f64 { 3.14159 }
fn get_char() -> char { 'A' }
fn get_unit() -> () { () }
engine.register_fn("get_number", get_number);
engine.register_fn("get_string", get_string);
engine.register_fn("get_boolean", get_boolean);
engine.register_fn("get_float", get_float);
engine.register_fn("get_char", get_char);
engine.register_fn("get_unit", get_unit);
```
### Dynamic Return Types
WE SHOULD TRY NOT TO DO THIS
For functions that may return different types based on conditions, use the `Dynamic` type:
```rust
fn get_value(which: i64) -> Dynamic {
match which {
0 => Dynamic::from(42),
1 => Dynamic::from("hello"),
2 => Dynamic::from(true),
3 => Dynamic::from(3.14159),
4 => {
let mut array = Array::new();
array.push(Dynamic::from(1));
array.push(Dynamic::from(2));
Dynamic::from_array(array)
},
5 => {
let mut map = Map::new();
map.insert("key".into(), "value".into());
Dynamic::from_map(map)
},
_ => Dynamic::UNIT,
}
}
engine.register_fn("get_value", get_value);
```
### Returning Collections
Rhai supports various collection types:
```rust
// Returning an array
fn get_array() -> Array {
let mut array = Array::new();
array.push(Dynamic::from(1));
array.push(Dynamic::from("hello"));
array.push(Dynamic::from(true));
array
}
// Returning a map
fn get_map() -> Map {
let mut map = Map::new();
map.insert("number".into(), 42.into());
map.insert("string".into(), "hello".into());
map.insert("boolean".into(), true.into());
map
}
// Returning a typed Vec (will be converted to Rhai Array)
fn get_numbers() -> Vec<i64> {
vec![1, 2, 3, 4, 5]
}
// Returning a HashMap (will be converted to Rhai Map)
fn get_config() -> HashMap<String, String> {
let mut map = HashMap::new();
map.insert("host".to_string(), "localhost".to_string());
map.insert("port".to_string(), "8080".to_string());
map
}
engine.register_fn("get_array", get_array);
engine.register_fn("get_map", get_map);
engine.register_fn("get_numbers", get_numbers);
engine.register_fn("get_config", get_config);
```
### Returning Custom Structs
For returning custom structs, ensure they implement the `Clone` trait:
```rust
#[derive(Debug, Clone)]
struct TestStruct {
x: i64,
name: String,
active: bool,
}
fn create_struct(value: i64, name: &str, active: bool) -> TestStruct {
TestStruct {
x: value,
name: name.to_string(),
active
}
}
fn get_struct_array() -> Vec<TestStruct> {
vec![
TestStruct { x: 1, name: "one".to_string(), active: true },
TestStruct { x: 2, name: "two".to_string(), active: false },
]
}
engine.register_type_with_name::<TestStruct>("TestStruct")
.register_fn("create_struct", create_struct)
.register_fn("get_struct_array", get_struct_array);
```
### Returning Results and Options
For functions that might fail or return optional values:
```rust
// Returning a Result
fn divide(a: i64, b: i64) -> Result<i64, Box<EvalAltResult>> {
if b == 0 {
Err("Division by zero".into())
} else {
Ok(a / b)
}
}
// Returning an Option (converted to Dynamic)
fn find_item(id: i64) -> Dynamic {
let item = lookup_item(id);
match item {
Some(value) => value.into(),
None => Dynamic::UNIT, // Rhai has no null, so use () for None
}
}
// Helper function returning Option
fn lookup_item(id: i64) -> Option<TestStruct> {
match id {
1 => Some(TestStruct { x: 1, name: "one".to_string(), active: true }),
2 => Some(TestStruct { x: 2, name: "two".to_string(), active: false }),
_ => None,
}
}
engine.register_fn("divide", divide);
engine.register_fn("find_item", find_item);
```
### Serialization and Deserialization
When working with JSON or other serialized formats:
```rust
use serde_json::{Value as JsonValue, json};
// Return JSON data as a Rhai Map
fn get_json_data() -> Result<Map, Box<EvalAltResult>> {
// Simulate fetching JSON data
let json_data = json!({
"name": "John Doe",
"age": 30,
"address": {
"street": "123 Main St",
"city": "Anytown"
},
"phones": ["+1-555-1234", "+1-555-5678"]
});
// Convert JSON to Rhai Map
json_to_rhai_value(json_data)
.and_then(|v| v.try_cast::<Map>().map_err(|_| "Expected a map".into()))
}
// Helper function to convert JSON Value to Rhai Dynamic
fn json_to_rhai_value(json: JsonValue) -> Result<Dynamic, Box<EvalAltResult>> {
match json {
JsonValue::Null => Ok(Dynamic::UNIT),
JsonValue::Bool(b) => Ok(b.into()),
JsonValue::Number(n) => {
if n.is_i64() {
Ok(n.as_i64().unwrap().into())
} else {
Ok(n.as_f64().unwrap().into())
}
},
JsonValue::String(s) => Ok(s.into()),
JsonValue::Array(arr) => {
let mut rhai_array = Array::new();
for item in arr {
rhai_array.push(json_to_rhai_value(item)?);
}
Ok(Dynamic::from_array(rhai_array))
},
JsonValue::Object(obj) => {
let mut rhai_map = Map::new();
for (k, v) in obj {
rhai_map.insert(k.into(), json_to_rhai_value(v)?);
}
Ok(Dynamic::from_map(rhai_map))
}
}
}
engine.register_fn("get_json_data", get_json_data);
```
### Working with Dynamic Type System
Understanding how to work with Rhai's Dynamic type system is essential:
```rust
// Function that examines a Dynamic value and returns information about it
fn inspect_value(value: Dynamic) -> Map {
let mut info = Map::new();
// Store the type name
info.insert("type".into(), value.type_name().into());
// Store specific type information
if value.is_int() {
info.insert("category".into(), "number".into());
info.insert("value".into(), value.clone());
} else if value.is_float() {
info.insert("category".into(), "number".into());
info.insert("value".into(), value.clone());
} else if value.is_string() {
info.insert("category".into(), "string".into());
info.insert("length".into(), value.clone_cast::<String>().len().into());
info.insert("value".into(), value.clone());
} else if value.is_array() {
info.insert("category".into(), "array".into());
info.insert("length".into(), value.clone_cast::<Array>().len().into());
} else if value.is_map() {
info.insert("category".into(), "map".into());
info.insert("keys".into(), value.clone_cast::<Map>().keys().len().into());
} else if value.is_bool() {
info.insert("category".into(), "boolean".into());
info.insert("value".into(), value.clone());
} else {
info.insert("category".into(), "other".into());
}
info
}
engine.register_fn("inspect", inspect_value);
```
## Native Function Handling
When working with native Rust functions in Rhai, there are several important considerations for handling different argument types, especially when dealing with complex data structures and error cases.
### Native Function Signature
Native Rust functions registered with Rhai can have one of two signatures:
1. **Standard Function Signature**: Functions with typed parameters
```rust
fn my_function(param1: Type1, param2: Type2, ...) -> ReturnType { ... }
```
2. **Dynamic Function Signature**: Functions that handle raw Dynamic values
```rust
fn my_dynamic_function(context: NativeCallContext, args: &mut [&mut Dynamic]) -> Result<Dynamic, Box<EvalAltResult>> { ... }
```
### Working with Raw Dynamic Arguments
The dynamic function signature gives you more control but requires manual type checking and conversion:
```rust
fn process_dynamic_args(context: NativeCallContext, args: &mut [&mut Dynamic]) -> Result<Dynamic, Box<EvalAltResult>> {
// Check number of arguments
if args.len() != 2 {
return Err("Expected exactly 2 arguments".into());
}
// Extract and convert the first argument to an integer
let arg1 = args[0].as_int().map_err(|_| "First argument must be an integer".into())?;
// Extract and convert the second argument to a string
let arg2 = args[1].as_str().map_err(|_| "Second argument must be a string".into())?;
// Process the arguments
let result = format!("{}: {}", arg2, arg1);
// Return the result as a Dynamic value
Ok(result.into())
}
// Register the function
engine.register_fn("process", process_dynamic_args);
```
### Handling Complex Struct Arguments
When working with complex struct arguments, you have several options:
#### Option 1: Use typed parameters (recommended for simple cases)
```rust
#[derive(Clone)]
struct ComplexData {
id: i64,
values: Vec<f64>,
}
fn process_complex(data: &mut ComplexData, factor: f64) -> f64 {
let sum: f64 = data.values.iter().sum();
data.values.push(sum * factor);
sum * factor
}
engine.register_fn("process_complex", process_complex);
```
#### Option 2: Use Dynamic parameters for more flexibility
```rust
fn process_complex_dynamic(context: NativeCallContext, args: &mut [&mut Dynamic]) -> Result<Dynamic, Box<EvalAltResult>> {
// Check arguments
if args.len() != 2 {
return Err("Expected exactly 2 arguments".into());
}
// Get mutable reference to the complex data
let data = args[0].write_lock::<ComplexData>()
.ok_or_else(|| "First argument must be ComplexData".into())?;
// Get the factor
let factor = args[1].as_float().map_err(|_| "Second argument must be a number".into())?;
// Process the data
let sum: f64 = data.values.iter().sum();
data.values.push(sum * factor);
Ok((sum * factor).into())
}
```
### Handling Variable Arguments
For functions that accept a variable number of arguments:
```rust
fn sum_all(context: NativeCallContext, args: &mut [&mut Dynamic]) -> Result<Dynamic, Box<EvalAltResult>> {
let mut total: i64 = 0;
for arg in args.iter() {
total += arg.as_int().map_err(|_| "All arguments must be integers".into())?;
}
Ok(total.into())
}
engine.register_fn("sum_all", sum_all);
// In Rhai:
// sum_all(1, 2, 3, 4, 5) -> 15
// sum_all(10, 20) -> 30
```
### Handling Optional Arguments
For functions with optional arguments, use function overloading:
```rust
fn create_person(name: &str) -> Person {
Person { name: name.to_string(), age: 30 } // Default age
}
fn create_person_with_age(name: &str, age: i64) -> Person {
Person { name: name.to_string(), age }
}
engine.register_fn("create_person", create_person);
engine.register_fn("create_person", create_person_with_age);
// In Rhai:
// create_person("John") -> Person with name "John" and age 30
// create_person("John", 25) -> Person with name "John" and age 25
```
### Handling Default Arguments
Rhai doesn't directly support default arguments, but you can simulate them:
```rust
fn configure(options: &mut Map) -> Result<(), Box<EvalAltResult>> {
// Check if certain options exist, if not, set defaults
if !options.contains_key("timeout") {
options.insert("timeout".into(), 30_i64.into());
}
if !options.contains_key("retry") {
options.insert("retry".into(), true.into());
}
Ok(())
}
engine.register_fn("configure", configure);
// In Rhai:
// let options = #{};
// configure(options);
// print(options.timeout); // Prints 30
```
### Handling Mutable and Immutable References
Rhai supports both mutable and immutable references:
```rust
// Function taking an immutable reference
fn get_name(person: &Person) -> String {
person.name.clone()
}
// Function taking a mutable reference
fn increment_age(person: &mut Person) {
person.age += 1;
}
engine.register_fn("get_name", get_name);
engine.register_fn("increment_age", increment_age);
```
### Converting Between Rust and Rhai Types
When you need to convert between Rust and Rhai types:
```rust
// Convert a Rust HashMap to a Rhai Map
fn create_config() -> Map {
let mut rust_map = HashMap::new();
rust_map.insert("server".to_string(), "localhost".to_string());
rust_map.insert("port".to_string(), "8080".to_string());
// Convert to Rhai Map
let mut rhai_map = Map::new();
for (k, v) in rust_map {
rhai_map.insert(k.into(), v.into());
}
rhai_map
}
// Convert a Rhai Array to a Rust Vec
fn process_array(arr: Array) -> Result<i64, Box<EvalAltResult>> {
// Convert to Rust Vec<i64>
let rust_vec: Result<Vec<i64>, _> = arr.iter()
.map(|v| v.as_int().map_err(|_| "Array must contain only integers".into()))
.collect();
let numbers = rust_vec?;
Ok(numbers.iter().sum())
}
```
## Complete Examples
### Example 1: Basic Function Registration and Struct Handling
```rust
use rhai::{Engine, EvalAltResult, RegisterFn};
#[derive(Debug, Clone)]
struct Person {
name: String,
age: i64,
}
impl Person {
fn new(name: &str, age: i64) -> Self {
Self {
name: name.to_string(),
age,
}
}
fn greet(&self) -> String {
format!("Hello, my name is {} and I am {} years old.", self.name, self.age)
}
fn have_birthday(&mut self) {
self.age += 1;
}
}
fn is_adult(person: &Person) -> bool {
person.age >= 18
}
fn main() -> Result<(), Box<EvalAltResult>> {
let mut engine = Engine::new();
// Register the Person type
engine
.register_type_with_name::<Person>("Person")
.register_fn("new_person", Person::new)
.register_fn("greet", Person::greet)
.register_fn("have_birthday", Person::have_birthday)
.register_fn("is_adult", is_adult);
// Run a script that uses the Person type
let result = engine.eval::<String>(r#"
let p = new_person("John", 17);
let greeting = p.greet();
if !is_adult(p) {
p.have_birthday();
}
greeting + " Now I am " + p.age.to_string() + " years old."
"#)?;
println!("{}", result);
Ok(())
}
```
### Example 2: Error Handling and Complex Return Types
```rust
use rhai::{Engine, EvalAltResult, Map, Dynamic};
use std::collections::HashMap;
#[derive(Debug, Clone)]
struct Product {
id: i64,
name: String,
price: f64,
}
fn get_product(id: i64) -> Result<Product, Box<EvalAltResult>> {
match id {
1 => Ok(Product { id: 1, name: "Laptop".to_string(), price: 999.99 }),
2 => Ok(Product { id: 2, name: "Phone".to_string(), price: 499.99 }),
_ => Err("Product not found".into())
}
}
fn calculate_total(products: Array) -> Result<f64, Box<EvalAltResult>> {
let mut total = 0.0;
for product_dynamic in products.iter() {
let product = product_dynamic.clone().try_cast::<Product>()
.map_err(|_| "Invalid product in array".into())?;
total += product.price;
}
Ok(total)
}
fn get_product_map() -> Map {
let mut map = Map::new();
map.insert("laptop".into(),
Dynamic::from(Product { id: 1, name: "Laptop".to_string(), price: 999.99 }));
map.insert("phone".into(),
Dynamic::from(Product { id: 2, name: "Phone".to_string(), price: 499.99 }));
map
}
fn main() -> Result<(), Box<EvalAltResult>> {
let mut engine = Engine::new();
engine
.register_type_with_name::<Product>("Product")
.register_fn("get_product", get_product)
.register_fn("calculate_total", calculate_total)
.register_fn("get_product_map", get_product_map);
let result = engine.eval::<f64>(r#"
let products = [];
// Try to get products
try {
products.push(get_product(1));
products.push(get_product(2));
products.push(get_product(3)); // This will throw an error
} catch(err) {
print(`Error: ${err}`);
}
// Get products from map
let product_map = get_product_map();
products.push(product_map.laptop);
calculate_total(products)
"#)?;
println!("Total: ${:.2}", result);
Ok(())
}
```

### Error Handling in Dynamic Functions
When working with the dynamic function signature, error handling is slightly different:
```rust
fn dynamic_function(ctx: NativeCallContext, args: &mut [&mut Dynamic]) -> Result<Dynamic, Box<EvalAltResult>> {
// Get the position information from the context
let pos = ctx.position();
// Validate arguments
if args.len() < 2 {
return Err(Box::new(EvalAltResult::ErrorRuntime(
format!("Expected at least 2 arguments, got {}", args.len()),
pos
)));
}
// Try to convert arguments with proper error handling
let arg1 = match args[0].as_int() {
Ok(val) => val,
Err(_) => return Err(Box::new(EvalAltResult::ErrorMismatchOutputType(
"Expected first argument to be an integer".into(),
pos,
"i64".into()
)))
};
// Process with error handling
if arg1 <= 0 {
return Err(Box::new(EvalAltResult::ErrorRuntime(
"First argument must be positive".into(),
pos
)));
}
// Return success
Ok(Dynamic::from(arg1 * 2))
}
```
## Advanced Patterns
### Working with Function Pointers
You can create function pointers that bind to Rust functions:
```rust
fn my_awesome_fn(ctx: NativeCallContext, args: &mut[&mut Dynamic]) -> Result<Dynamic, Box<EvalAltResult>> {
// Check number of arguments
if args.len() != 2 {
return Err("one argument is required, plus the object".into());
}
// Get call arguments
let x = args[1].try_cast::<i64>().map_err(|_| "argument must be an integer".into())?;
// Get mutable reference to the object map, which is passed as the first argument
let map = &mut *args[0].as_map_mut().map_err(|_| "object must be a map".into())?;
// Do something awesome here ...
let result = x * 2;
Ok(result.into())
}
// Register a function to create a pre-defined object
engine.register_fn("create_awesome_object", || {
// Use an object map as base
let mut map = Map::new();
// Create a function pointer that binds to 'my_awesome_fn'
let fp = FnPtr::from_fn("awesome", my_awesome_fn)?;
// ^ name of method
// ^ native function
// Store the function pointer in the object map
map.insert("awesome".into(), fp.into());
Ok(Dynamic::from_map(map))
});
```
### Creating Rust Closures from Rhai Functions
You can encapsulate a Rhai script as a Rust closure:
```rust
use rhai::{Engine, Func};
let engine = Engine::new();
let script = "fn calc(x, y) { x + y.len < 42 }";
// Create a Rust closure from a Rhai function
let func = Func::<(i64, &str), bool>::create_from_script(
engine, // the 'Engine' is consumed into the closure
script, // the script
"calc" // the entry-point function name
)?;
// Call the closure
let result = func(123, "hello")?;
// Pass it as a callback to another function
schedule_callback(func);
```
### Calling Rhai Functions from Rust
You can call Rhai functions from Rust:
```rust
// Compile the script to AST
let ast = engine.compile(script)?;
// Create a custom 'Scope'
let mut scope = Scope::new();
// Add variables to the scope
scope.push("my_var", 42_i64);
scope.push("my_string", "hello, world!");
scope.push_constant("MY_CONST", true);
// Call a function defined in the script
let result = engine.call_fn::<i64>(&mut scope, &ast, "hello", ("abc", 123_i64))?;
// For a function with one parameter, use a tuple with a trailing comma
let result = engine.call_fn::<i64>(&mut scope, &ast, "hello", (123_i64,))?;
// For a function with no parameters
let result = engine.call_fn::<i64>(&mut scope, &ast, "hello", ())?;
```

## Best Practices and Optimization
When wrapping Rust functions for use with Rhai, following these best practices will help you create efficient, maintainable, and robust code.
### Performance Considerations
1. **Minimize Cloning**: Rhai often requires cloning data, but you can minimize this overhead:
```rust
// Prefer immutable references when possible
fn process_data(data: &MyStruct) -> i64 {
// Work with data without cloning
data.value * 2
}
// Use mutable references for in-place modifications
fn update_data(data: &mut MyStruct) {
data.value += 1;
}
```
2. **Avoid Excessive Type Conversions**: Converting between Rhai's Dynamic type and Rust types has overhead:
```rust
// Inefficient - multiple conversions
fn process_inefficient(ctx: NativeCallContext, args: &mut [&mut Dynamic]) -> Result<Dynamic, Box<EvalAltResult>> {
let value = args[0].as_int()?;
let result = value * 2;
Ok(Dynamic::from(result))
}
// More efficient - use typed parameters when possible
fn process_efficient(value: i64) -> i64 {
value * 2
}
```
3. **Batch Operations**: For operations on collections, batch processing is more efficient:
```rust
// Process an entire array at once rather than element by element
fn sum_array(arr: Array) -> Result<i64, Box<EvalAltResult>> {
arr.iter()
.map(|v| v.as_int())
.collect::<Result<Vec<i64>, _>>()
.map(|nums| nums.iter().sum())
.map_err(|_| "Array must contain only integers".into())
}
```
4. **Compile Scripts Once**: Reuse compiled ASTs for scripts that are executed multiple times:
```rust
// Compile once
let ast = engine.compile(script)?;
// Execute multiple times with different parameters
for i in 0..10 {
let result = engine.eval_ast::<i64>(&ast)?;
println!("Result {}: {}", i, result);
}
```
### Thread Safety
1. **Use Sync Mode When Needed**: If you need thread safety, use the `sync` feature:
```rust
// In Cargo.toml
// rhai = { version = "1.x", features = ["sync"] }
// This creates a thread-safe engine
let engine = Engine::new();
// Now you can safely share the engine between threads
std::thread::spawn(move || {
let result = engine.eval::<i64>("40 + 2")?;
println!("Result: {}", result);
});
```
2. **Clone the Engine for Multiple Threads**: When not using `sync`, clone the engine for each thread:
```rust
let engine = Engine::new();
let handles: Vec<_> = (0..5).map(|i| {
let engine_clone = engine.clone();
std::thread::spawn(move || {
let result = engine_clone.eval::<i64>(&format!("{} + 2", i * 10))?;
println!("Thread {}: {}", i, result);
})
}).collect();
for handle in handles {
handle.join().unwrap();
}
```
### Memory Management
1. **Control Scope Size**: Be mindful of the size of your scopes:
```rust
// Create a new scope for each operation to avoid memory buildup
for item in items {
let mut scope = Scope::new();
scope.push("item", item);
engine.eval_with_scope::<()>(&mut scope, "process(item)")?;
}
```
2. **Limit Script Complexity**: Use engine options to limit script complexity:
```rust
let mut engine = Engine::new();
// Set limits to prevent scripts from consuming too many resources
engine.set_max_expr_depths(64, 64) // Max expression/statement depth
.set_max_function_expr_depth(64) // Max function depth
.set_max_array_size(10000) // Max array size
.set_max_map_size(10000) // Max map size
.set_max_string_size(10000) // Max string size
.set_max_call_levels(64); // Max call stack depth
```
3. **Use Shared Values Carefully**: Shared values (via closures) have reference-counting overhead:
```rust
// Avoid unnecessary capturing in closures when possible
engine.register_fn("process", |x: i64| x * 2);
// Instead of capturing large data structures
let large_data = vec![1, 2, 3, /* ... thousands of items ... */];
engine.register_fn("process_data", move |idx: i64| {
if idx >= 0 && (idx as usize) < large_data.len() {
large_data[idx as usize]
} else {
0
}
});
// Consider registering a lookup function instead
let large_data = std::sync::Arc::new(vec![1, 2, 3, /* ... thousands of items ... */]);
let data_ref = large_data.clone();
engine.register_fn("lookup", move |idx: i64| {
if idx >= 0 && (idx as usize) < data_ref.len() {
data_ref[idx as usize]
} else {
0
}
});
```
### API Design
1. **Consistent Naming**: Use consistent naming conventions:
```rust
// Good: Consistent naming pattern
engine.register_fn("create_user", create_user)
.register_fn("update_user", update_user)
.register_fn("delete_user", delete_user);
// Bad: Inconsistent naming
engine.register_fn("create_user", create_user)
.register_fn("user_update", update_user)
.register_fn("remove", delete_user);
```
2. **Logical Function Grouping**: Group related functions together:
```rust
// Register all string-related functions together
engine.register_fn("str_length", |s: &str| s.len() as i64)
.register_fn("str_uppercase", |s: &str| s.to_uppercase())
.register_fn("str_lowercase", |s: &str| s.to_lowercase());
// Register all math-related functions together
engine.register_fn("math_sin", |x: f64| x.sin())
.register_fn("math_cos", |x: f64| x.cos())
.register_fn("math_tan", |x: f64| x.tan());
```
3. **Comprehensive Documentation**: Document your API thoroughly:
```rust
// Add documentation for script writers
let mut engine = Engine::new();
#[cfg(feature = "metadata")]
{
// Add function documentation
engine.register_fn("calculate_tax", calculate_tax)
.register_fn_metadata("calculate_tax", |metadata| {
metadata.set_doc_comment("Calculates tax based on income and rate.\n\nParameters:\n- income: Annual income\n- rate: Tax rate (0.0-1.0)\n\nReturns: Calculated tax amount");
});
}
```

# Buildah Debug Implementation Plan
## Current State
1. The `Builder` struct already has a `debug` field and methods to get and set it (`debug()` and `set_debug()`).
2. There's a thread-local `DEBUG` variable with functions to get and set it.
3. The `execute_buildah_command` function checks the thread-local debug flag and outputs some debug information.
4. There's an unused `execute_buildah_command_with_debug` function that takes a `Builder` reference.
## Requirements
1. Use only the Builder's debug flag, not the thread-local debug flag.
2. When debug is true, output stdout/stderr regardless of whether the command succeeds or fails.
3. If debug is false but there's an error, still output all information.
## Implementation Plan
### 1. Keep the Existing Thread-Local DEBUG Variable
We'll keep the existing thread-local DEBUG variable that's already in the code:
```rust
// Thread-local storage for debug flag
thread_local! {
static DEBUG: std::cell::RefCell<bool> = std::cell::RefCell::new(false);
}
```
### 2. Modify the Builder Methods to Set/Clear the Thread-Local Debug Flag
We'll modify each Builder method to set the thread-local debug flag from the Builder's debug flag before calling `execute_buildah_command` and restore it afterward:
```rust
pub fn run(&self, command: &str) -> Result<CommandResult, BuildahError> {
if let Some(container_id) = &self.container_id {
// Save the current debug flag
let previous_debug = thread_local_debug();
// Set the thread-local debug flag from the Builder's debug flag
set_thread_local_debug(self.debug);
// Execute the command
let result = execute_buildah_command(&["run", container_id, "sh", "-c", command]);
// Restore the previous debug flag
set_thread_local_debug(previous_debug);
result
} else {
Err(BuildahError::Other("No container ID available".to_string()))
}
}
```
### 3. Keep the Existing execute_buildah_command Function
The existing `execute_buildah_command` function already checks the thread-local debug flag, so we don't need to modify it:
```rust
pub fn execute_buildah_command(args: &[&str]) -> Result<CommandResult, BuildahError> {
// Get the debug flag from thread-local storage
let debug = thread_local_debug();
if debug {
println!("Executing buildah command: buildah {}", args.join(" "));
}
// ... rest of the function ...
}
```
### 4. Update the execute_buildah_command Function to Output stdout/stderr
We need to modify the `execute_buildah_command` function to output stdout/stderr when debug is true, regardless of success/failure:
```rust
pub fn execute_buildah_command(args: &[&str]) -> Result<CommandResult, BuildahError> {
// Get the debug flag from thread-local storage
let debug = thread_local_debug();
if debug {
println!("Executing buildah command: buildah {}", args.join(" "));
}
let output = Command::new("buildah")
.args(args)
.output();
match output {
Ok(output) => {
let stdout = String::from_utf8_lossy(&output.stdout).to_string();
let stderr = String::from_utf8_lossy(&output.stderr).to_string();
let result = CommandResult {
stdout,
stderr,
success: output.status.success(),
code: output.status.code().unwrap_or(-1),
};
// Always output stdout/stderr when debug is true
if debug {
if !result.stdout.is_empty() {
println!("Command stdout: {}", result.stdout);
}
if !result.stderr.is_empty() {
println!("Command stderr: {}", result.stderr);
}
if result.success {
println!("Command succeeded with code {}", result.code);
} else {
println!("Command failed with code {}", result.code);
}
}
if result.success {
Ok(result)
} else {
// If command failed and debug is false, output stderr
if !debug {
println!("Command failed with code {}: {}", result.code, result.stderr.trim());
}
Err(BuildahError::CommandFailed(format!("Command failed with code {}: {}",
result.code, result.stderr.trim())))
}
},
Err(e) => {
// Always output error information
println!("Command execution failed: {}", e);
Err(BuildahError::CommandExecutionFailed(e))
}
}
}
```
### 5. Handle Static Methods
For static methods, we'll just call `execute_buildah_command` directly, which will use the thread-local debug flag:
```rust
pub fn images() -> Result<Vec<Image>, BuildahError> {
let result = execute_buildah_command(&["images", "--json"])?;
// Rest of the method...
}
```
If we want to support debugging in static methods, we could add an optional debug parameter:
```rust
pub fn images(debug: bool) -> Result<Vec<Image>, BuildahError> {
// Save the current debug flag
let previous_debug = thread_local_debug();
// Set the thread-local debug flag
set_thread_local_debug(debug);
// Execute the command
let result = execute_buildah_command(&["images", "--json"]);
// Restore the previous debug flag
set_thread_local_debug(previous_debug);
// Process the result
match result {
Ok(cmd_result) => {
// Parse JSON and return images...
},
Err(e) => Err(e),
}
}
// Backward compatibility method
pub fn images() -> Result<Vec<Image>, BuildahError> {
Self::images(false)
}
```
### 6. Update Rhai Bindings
We still need to update the Rhai bindings to expose the debug functionality:
```rust
// Add a debug getter and setter
engine.register_get("debug", |builder: &mut Builder| builder.debug());
engine.register_set("debug", |builder: &mut Builder, debug: bool| { builder.set_debug(debug); });
```
### 7. Remove Unused Code
We can remove the unused `execute_buildah_command_with_debug` function.
## Implementation Flow
1. Modify the `execute_buildah_command` function to output stdout/stderr when debug is true
2. Update all Builder methods to set/restore the thread-local debug flag
3. Update static methods to optionally accept a debug parameter
4. Update Rhai bindings to expose the debug functionality
5. Remove unused code
## Benefits
1. Minimal changes to the existing codebase
2. No changes to function signatures
3. Backward compatibility with existing code
4. Improved debugging capabilities

# RFS Wrapper Implementation Plan
## Overview
We'll create a Rust wrapper for the RFS (Remote File System) tool that follows the builder pattern, similar to the existing implementations for buildah and nerdctl in the codebase. This wrapper will provide a fluent API for mounting, unmounting, listing mounts, configuring mount options, and packing directories into filesystem layers.
## Module Structure
```
src/virt/rfs/
├── mod.rs # Module exports and common types
├── cmd.rs # Command execution functions
├── mount.rs # Mount operations
├── pack.rs # Packing operations
├── builder.rs # Builder pattern implementation
├── types.rs # Type definitions
└── error.rs # Error handling
```
## Implementation Details
### 1. Error Handling
```rust
// error.rs
#[derive(Debug)]
pub enum RfsError {
CommandFailed(String),
InvalidArgument(String),
MountFailed(String),
UnmountFailed(String),
ListFailed(String),
PackFailed(String),
Other(String),
}
impl std::fmt::Display for RfsError {
// Implementation
}
impl std::error::Error for RfsError {
// Implementation
}
```
### 2. Command Execution
```rust
// cmd.rs
use crate::process::{run_command, CommandResult};
use super::error::RfsError;
pub fn execute_rfs_command(args: &[&str]) -> Result<CommandResult, RfsError> {
// Implementation similar to buildah and nerdctl
}
```
### 3. Types
```rust
// types.rs
#[derive(Debug, Clone)]
pub struct Mount {
pub id: String,
pub source: String,
pub target: String,
pub fs_type: String,
pub options: Vec<String>,
}
#[derive(Debug, Clone)]
pub enum MountType {
Local,
SSH,
S3,
WebDAV,
// Other mount types
}
#[derive(Debug, Clone)]
pub struct StoreSpec {
pub spec_type: String,
pub options: std::collections::HashMap<String, String>,
}
impl StoreSpec {
pub fn new(spec_type: &str) -> Self {
Self {
spec_type: spec_type.to_string(),
options: std::collections::HashMap::new(),
}
}
pub fn with_option(mut self, key: &str, value: &str) -> Self {
self.options.insert(key.to_string(), value.to_string());
self
}
pub fn to_string(&self) -> String {
let mut result = self.spec_type.clone();
if !self.options.is_empty() {
result.push_str(":");
let options: Vec<String> = self.options
.iter()
.map(|(k, v)| format!("{}={}", k, v))
.collect();
result.push_str(&options.join(","));
}
result
}
}
```
### 4. Builder Pattern
```rust
// builder.rs
use std::collections::HashMap;
use super::{Mount, MountType, RfsError, execute_rfs_command, StoreSpec};
#[derive(Clone)]
pub struct RfsBuilder {
source: String,
target: String,
mount_type: MountType,
options: HashMap<String, String>,
mount_id: Option<String>,
debug: bool,
}
impl RfsBuilder {
pub fn new(source: &str, target: &str, mount_type: MountType) -> Self {
Self {
source: source.to_string(),
target: target.to_string(),
mount_type,
options: HashMap::new(),
mount_id: None,
debug: false,
}
}
pub fn with_option(mut self, key: &str, value: &str) -> Self {
self.options.insert(key.to_string(), value.to_string());
self
}
pub fn with_options(mut self, options: HashMap<&str, &str>) -> Self {
for (key, value) in options {
self.options.insert(key.to_string(), value.to_string());
}
self
}
pub fn with_debug(mut self, debug: bool) -> Self {
self.debug = debug;
self
}
pub fn mount(self) -> Result<Mount, RfsError> {
// Implementation
}
pub fn unmount(&self) -> Result<(), RfsError> {
// Implementation
}
// Other methods
}
// Packing functionality
pub struct PackBuilder {
directory: String,
output: String,
store_specs: Vec<StoreSpec>,
debug: bool,
}
impl PackBuilder {
pub fn new(directory: &str, output: &str) -> Self {
Self {
directory: directory.to_string(),
output: output.to_string(),
store_specs: Vec::new(),
debug: false,
}
}
pub fn with_store_spec(mut self, store_spec: StoreSpec) -> Self {
self.store_specs.push(store_spec);
self
}
pub fn with_store_specs(mut self, store_specs: Vec<StoreSpec>) -> Self {
self.store_specs.extend(store_specs);
self
}
pub fn with_debug(mut self, debug: bool) -> Self {
self.debug = debug;
self
}
pub fn pack(self) -> Result<(), RfsError> {
// Implementation for packing a directory into a filesystem layer
let mut args = vec!["pack"];
// Add output file
args.push("-m");
args.push(&self.output);
// Add store specs
if !self.store_specs.is_empty() {
args.push("-s");
let specs: Vec<String> = self.store_specs
.iter()
.map(|spec| spec.to_string())
.collect();
args.push(&specs.join(","));
}
// Add directory
args.push(&self.directory);
// Convert to string slices for the command
let args_str: Vec<&str> = args.iter().map(|s| s.as_str()).collect();
// Execute the command
let result = execute_rfs_command(&args_str)?;
// Check for errors
if !result.success {
return Err(RfsError::PackFailed(result.stderr));
}
Ok(())
}
}
```
### 5. Mount Operations
```rust
// mount.rs
use super::{RfsBuilder, Mount, RfsError, execute_rfs_command};
pub fn list_mounts() -> Result<Vec<Mount>, RfsError> {
// Implementation
}
pub fn unmount_all() -> Result<(), RfsError> {
// Implementation
}
// Other mount-related functions
```
### 6. Pack Operations
```rust
// pack.rs
use super::{PackBuilder, StoreSpec, RfsError, execute_rfs_command};
pub fn pack_directory(directory: &str, output: &str, store_specs: &[StoreSpec]) -> Result<(), RfsError> {
PackBuilder::new(directory, output)
.with_store_specs(store_specs.to_vec())
.pack()
}
// Other pack-related functions
```
### 7. Module Exports
```rust
// mod.rs
mod cmd;
mod error;
mod mount;
mod pack;
mod builder;
mod types;
pub use error::RfsError;
pub use builder::{RfsBuilder, PackBuilder};
pub use types::{Mount, MountType, StoreSpec};
pub use mount::{list_mounts, unmount_all};
pub use pack::pack_directory;
// Re-export the execute_rfs_command function for use in other modules
pub(crate) use cmd::execute_rfs_command;
```
## Usage Examples
### Mounting Example
```rust
use crate::virt::rfs::{RfsBuilder, MountType};
// Create a new RFS mount with builder pattern
let mount = RfsBuilder::new("user@example.com:/remote/path", "/local/mount/point", MountType::SSH)
.with_option("port", "2222")
.with_option("identity_file", "/path/to/key")
.with_debug(true)
.mount()?;
// List all mounts
let mounts = list_mounts()?;
for mount in mounts {
println!("Mount ID: {}, Source: {}, Target: {}", mount.id, mount.source, mount.target);
}
// Unmount
mount.unmount()?;
```
### Packing Example
```rust
use crate::virt::rfs::{PackBuilder, StoreSpec};
// Create store specifications
let store_spec1 = StoreSpec::new("file")
.with_option("path", "/path/to/store");
let store_spec2 = StoreSpec::new("s3")
.with_option("bucket", "my-bucket")
.with_option("region", "us-east-1");
// Pack a directory with builder pattern
let result = PackBuilder::new("/path/to/directory", "output.fl")
.with_store_spec(store_spec1)
.with_store_spec(store_spec2)
.with_debug(true)
.pack()?;
// Or use the convenience function
pack_directory("/path/to/directory", "output.fl", &[store_spec1, store_spec2])?;
```
## Rhai Integration
We'll also need to create a Rhai module to expose the RFS functionality to Rhai scripts:
```rust
// src/rhai/rfs.rs
use rhai::{Engine, EvalAltResult, RegisterFn};
use crate::virt::rfs::{RfsBuilder, MountType, list_mounts, unmount_all, PackBuilder, StoreSpec};
pub fn register(engine: &mut Engine) -> Result<(), Box<EvalAltResult>> {
// Register RFS functions
engine.register_fn("rfs_mount", rfs_mount);
engine.register_fn("rfs_unmount", rfs_unmount);
engine.register_fn("rfs_list_mounts", rfs_list_mounts);
engine.register_fn("rfs_unmount_all", rfs_unmount_all);
engine.register_fn("rfs_pack", rfs_pack);
Ok(())
}
// Function implementations
fn rfs_mount(source: &str, target: &str, mount_type: &str, options_map: rhai::Map) -> Result<(), Box<EvalAltResult>> {
// Implementation
}
fn rfs_unmount(target: &str) -> Result<(), Box<EvalAltResult>> {
// Implementation
}
fn rfs_list_mounts() -> Result<rhai::Array, Box<EvalAltResult>> {
// Implementation
}
fn rfs_unmount_all() -> Result<(), Box<EvalAltResult>> {
// Implementation
}
fn rfs_pack(directory: &str, output: &str, store_specs: &str) -> Result<(), Box<EvalAltResult>> {
// Implementation
}
```
## Implementation Flow
Here's a diagram showing the flow of the implementation:
```mermaid
classDiagram
class RfsBuilder {
+String source
+String target
+MountType mount_type
+HashMap options
+Option~String~ mount_id
+bool debug
+new(source, target, mount_type)

}
class PackBuilder {
+String directory
+String output
+Vec~StoreSpec~ store_specs
+bool debug

+with_store_spec(store_spec)
+with_store_specs(store_specs)
+with_debug(debug)
+pack()
}
class Mount {

}
class MountType {

+to_string()
}
class RfsError {
<<enumeration>>

}
RfsBuilder --> Mount : creates
RfsBuilder --> RfsError : may throw
RfsBuilder --> MountType : uses
PackBuilder --> RfsError : may throw
PackBuilder --> StoreSpec : uses
Mount --> RfsError : may throw
```
## Implementation Steps
1. Create the directory structure for the RFS module
2. Implement the error handling module
3. Implement the command execution module
4. Define the types for mounts, mount operations, and store specifications
5. Implement the builder pattern for RFS operations (mount and pack)
6. Implement the mount operations
7. Implement the pack operations
8. Create the module exports
9. Add Rhai integration
10. Write tests for the implementation
11. Update documentation

# Container Builder
The Buildah module provides functions for working with containers and images using the Buildah tool. Buildah helps you create and manage container images.
## Builder Pattern
The Buildah module now supports a Builder pattern, which provides a more intuitive and flexible way to work with containers and images.
### Creating a Builder
```js
// Create a builder with a name and base image
let builder = bah_new("my-container", "alpine:latest");
// Access builder properties
let container_id = builder.container_id;
let name = builder.name;
let image = builder.image;
```
### Builder Methods
The Builder object provides the following methods:
- `run(command)`: Run a command in the container
- `run_with_isolation(command, isolation)`: Run a command with specified isolation
- `copy(source, dest)`: Copy files into the container
- `add(source, dest)`: Add files into the container
- `commit(image_name)`: Commit the container to an image
- `remove()`: Remove the container
- `reset()`: Remove the container and clear the container_id
- `config(options)`: Configure container metadata
- `set_entrypoint(entrypoint)`: Set the entrypoint for the container
- `set_cmd(cmd)`: Set the default command for the container
- `debug_mode`: Get or set the debug flag (true/false)
- `write_content(content, dest_path)`: Write content to a file in the container
- `read_content(source_path)`: Read content from a file in the container
- `images()`: List images in local storage
- `image_remove(image)`: Remove an image
- `image_pull(image, tls_verify)`: Pull an image from a registry
- `image_push(image, destination, tls_verify)`: Push an image to a registry
- `image_tag(image, new_name)`: Add a tag to an image
- `build(tag, context_dir, file, isolation)`: Build an image from a Dockerfile
- `build(tag, context_dir, file, isolation)`: Build an image from a Dockerfile
### Example
```js
// Create a builder
let builder = bah_new("my-container", "alpine:latest");
// Enable debug mode to see command output
builder.debug_mode = true;
// Reset the builder to remove any existing container
builder.reset();
// Create a new container
builder = bah_new("my-container", "alpine:latest");
// Run a command
let result = builder.run("echo 'Hello from container'");
println(`Command output: ${result.stdout}`);
// Write content directly to a file in the container
let script_content = `#!/bin/sh
echo "Hello from startup script"
`;
builder.write_content(script_content, "/start.sh");
builder.run("chmod +x /start.sh");
// Set the entrypoint for the container
builder.set_entrypoint("/start.sh");
// Add a file
file_write("test_file.txt", "Test content");
builder.add("test_file.txt", "/");
// Commit to an image
builder.commit("my-custom-image:latest");
// Clean up
builder.remove();
delete("test_file.txt");
```
## Image Information
### Image Properties
When working with images, you can access the following information:
- `id`: The unique identifier for the image
- `names`: A list of names/tags for the image
- `name`: The primary name of the image, or `<none>` if the image has no names
- `size`: The size of the image
- `created`: When the image was created
## Builder Methods
### `bah_new(name, image)`
Creates a new Builder object for working with a container.
**Parameters:**
- `name` (string): The name to give the container
- `image` (string): The name or ID of the image to create the container from
**Returns:** A Builder object if successful.
**Example:**
```js
// Create a new Builder
let builder = bah_new("my-container", "alpine:latest");
```
**Notes:**
- If a container with the given name already exists, it will be reused instead of creating a new one
- The Builder object provides methods for working with the container
### `reset()`
Resets a Builder by removing the container and clearing the container_id. This allows you to start fresh with the same Builder object.
**Returns:** Nothing.
**Example:**
```js
// Create a Builder
let builder = bah_new("my-container", "alpine:latest");
// Reset the Builder to remove the container
builder.reset();
// Create a new container with the same name
builder = bah_new("my-container", "alpine:latest");
```
### `debug_mode`
Get or set the debug flag for the Builder. When debug mode is enabled, all buildah commands will output their stdout/stderr, making it easier to debug issues.
**Example:**
```js
// Create a Builder
let builder = bah_new("my-container", "alpine:latest");
// Enable debug mode
builder.debug_mode = true;
// Run a command with debug output
builder.run("echo 'Hello with debug'");
// Disable debug mode
builder.debug_mode = false;
```
### `set_entrypoint(entrypoint)`
Sets the entrypoint for the container. The entrypoint is the command that will be executed when the container starts.
**Parameters:**
- `entrypoint` (string): The entrypoint command
**Returns:** Command result if successful.
**Example:**
```js
// Create a Builder
let builder = bah_new("my-container", "alpine:latest");
// Set the entrypoint
builder.set_entrypoint("/start.sh");
```
### `set_cmd(cmd)`
Sets the default command for the container. This is used as arguments to the entrypoint.
**Parameters:**
- `cmd` (string): The default command
**Returns:** Command result if successful.
**Example:**
```js
// Create a Builder
let builder = bah_new("my-container", "alpine:latest");
// Set the default command
builder.set_cmd("--verbose");
```
### `write_content(content, dest_path)`
Writes content to a file in the container.
**Parameters:**
- `content` (string): The content to write
- `dest_path` (string): The destination path in the container
**Returns:** Command result if successful.
**Example:**
```js
// Create a Builder
let builder = bah_new("my-container", "alpine:latest");
// Write content to a file
let content = "Hello, world!";
builder.write_content(content, "/hello.txt");
```
### `read_content(source_path)`
Reads content from a file in the container.
**Parameters:**
- `source_path` (string): The source path in the container
**Returns:** The file content as a string if successful.
**Example:**
```js
// Create a Builder
let builder = bah_new("my-container", "alpine:latest");
// Write content to a file
builder.write_content("Hello, world!", "/hello.txt");
// Read content from the file
let content = builder.read_content("/hello.txt");
println(content); // Outputs: Hello, world!
```

# Git
This module provides HeroScript wrappers for the Git functionality in SAL.
> **Note:** The constructor for GitTree has been renamed from `new()` to `gittree_new()` to avoid confusion with other constructors. This makes the interface more explicit and less likely to cause naming conflicts.
## Object-Oriented Design
The Git module follows an object-oriented design with two main classes:
1. **GitTree** - Represents a collection of git repositories under a base path
- Created with `gittree_new(base_path)`
- Methods for listing, finding, and getting repositories
2. **GitRepo** - Represents a single git repository
- Obtained from GitTree's `get()` method
- Methods for common git operations: pull, reset, push, commit
This design allows for a more intuitive and flexible interface, with method chaining for complex operations.
## Creating a GitTree
The GitTree object is the main entry point for git operations. It represents a collection of git repositories under a base path.
```js
// Create a new GitTree with a base path
let git_tree = gittree_new("/root/code");
print(`Created GitTree with base path: /home/user/code`);
```
## Finding Repositories
### List All Repositories
```js
// List all git repositories under the base path
let repos = git_tree.list();
print(`Found ${repos.len()} repositories`);
// Print the repositories
for repo in repos {
print(` - ${repo}`);
}
```
### Find Repositories Matching a Pattern
```js
// Find repositories matching a pattern
// Use a wildcard (*) suffix to find multiple matches
let matching_repos = git_tree.find("my-project*");
print("Matching repositories:");
for repo in matching_repos {
print(` - ${repo}`);
}
// Find a specific repository (must match exactly one)
let specific_repo = git_tree.find("unique-project")[0];
print(`Found specific repository: ${specific_repo}`);
```
## Working with Repositories
### Get Repository Objects
```js
// Get GitRepo objects for repositories matching a pattern
let repos = git_tree.get("my-project*");
print(`Found ${repos.len()} repositories`);
// Get a specific repository
let repo = git_tree.get("unique-project")[0];
print(`Working with repository: ${repo.path()}`);
```
### Clone a Repository
```js
// Clone a repository by URL
// This will clone the repository to the base path of the GitTree
let repos = git_tree.get("https://github.com/username/repo.git");
let repo = repos[0];
print(`Repository cloned to: ${repo.path()}`);
```
### Check for Changes
```js
// Check if a repository has uncommitted changes
let repo = git_tree.get("my-project")[0];
if repo.has_changes() {
print("Repository has uncommitted changes");
} else {
print("Repository is clean");
}
```
## Repository Operations
### Pull Changes
```js
// Pull the latest changes from the remote
// This will fail if there are uncommitted changes
let repo = git_tree.get("my-project")[0];
let result = repo.pull();
print("Repository updated successfully");
```
### Reset Local Changes
```js
// Reset any local changes in the repository
let repo = git_tree.get("my-project")[0];
let result = repo.reset();
print("Repository reset successfully");
```
### Commit Changes
```js
// Commit changes in the repository
let repo = git_tree.get("my-project")[0];
let result = repo.commit("Fix bug in login form");
print("Changes committed successfully");
```
### Push Changes
```js
// Push changes to the remote
let repo = git_tree.get("my-project")[0];
let result = repo.push();
print("Changes pushed successfully");
```
## Method Chaining
The GitRepo methods can be chained together for more complex operations:
```js
// Commit changes and push them to the remote
let repo = git_tree.get("my-project")[0];
let result = repo.commit("Add new feature").push();
print("Changes committed and pushed successfully");
// Reset local changes, pull the latest changes, and commit new changes
let repo = git_tree.get("my-project")[0];
let result = repo.reset().pull().commit("Update dependencies");
print("Repository updated successfully");
```
## Complete Example
```js
// Create a new GitTree
let home_dir = env("HOME");
let git_tree = gittree_new(`${home_dir}/code`);
// Clone a repository
let repos = git_tree.get("https://github.com/username/example-repo.git");
let repo = repos[0];
print(`Cloned repository to: ${repo.path()}`);
// Make some changes (using OS module functions)
let file_path = `${repo.path()}/README.md`;
let content = "# Example Repository\n\nThis is an example repository.";
write_file(file_path, content);
// Commit and push the changes
let result = repo.commit("Update README.md").push();
print("Changes committed and pushed successfully");
// List all repositories
let all_repos = git_tree.list();
print("All repositories:");
for repo_path in all_repos {
print(` - ${repo_path}`);
}
```
## Error Handling
All methods in the Git module return a Result type, which means they can either succeed or fail with an error. If an error occurs, it will be propagated to the HeroScript script as a runtime error.
For example, if you try to clone a repository that doesn't exist:
```js
// Try to clone a non-existent repository
try {
let git_tree = gittree_new("/root/code");
let repos = git_tree.get("https://github.com/nonexistent/repo.git");
print("This will not be executed if the repository doesn't exist");
} catch(err) {
print(`Error: ${err}`); // Will print the error message from git
}
```
Common errors include:
- Invalid URL
- Repository not found
- Authentication failure
- Network issues
- Local changes exist when trying to pull

# Container Manager
The Container Manager module provides a comprehensive API for working with containers using nerdctl. It offers a modern builder pattern approach for container management.
## Container Builder Pattern
The Container Builder Pattern allows for fluent, chainable configuration of containers. This pattern makes container creation more readable and maintainable by allowing you to build complex container configurations step by step.
### Creating a Container
Start by creating a new container instance:
```rhai
// Create an empty container with just a name
let container = nerdctl_container_new("my-container");
// Or create a container from an image
let container = nerdctl_container_from_image("my-container", "nginx:latest");
```
### Configuring the Container
Once you have a container instance, you can configure it using the various builder methods:
```rhai
// Configure the container with various options
let container = nerdctl_container_from_image("web-server", "nginx:latest")
.with_port("8080:80") // Map port 8080 to container port 80
.with_volume("/host/path:/container/path") // Mount a volume
.with_env("NGINX_HOST", "localhost") // Set an environment variable
.with_network("bridge") // Set the network
.with_detach(true); // Run in detached mode
```
### Resetting Container Configuration
If you need to reset the container configuration to its default state while keeping the name and image:
```rhai
// Reset the container configuration
let container = nerdctl_container_from_image("web-server", "nginx:latest")
.reset() // Reset all configuration to defaults
.with_port("8080:80") // Start configuring again
.with_detach(true);
```
### Building and Starting the Container
After configuring the container, you can build and start it:
```rhai
// Build the container (creates it but doesn't start it)
let built_container = container.build();
// Start the container
let start_result = built_container.start();
// Check if the container started successfully
if (start_result.success) {
println("Container started successfully!");
} else {
println(`Failed to start container: ${start_result.stderr}`);
}
```
### Container Lifecycle Operations
Once your container is running, you can perform various operations:
```rhai
// Execute a command in the container
let exec_result = container.exec("ls -la");
// Get container logs
let logs = container.logs();
// Stop the container
let stop_result = container.stop();
// Remove the container
let remove_result = container.remove();
```
## Available Builder Methods
The Container Builder Pattern provides the following methods for configuring containers:
| Method | Description | Example |
| -------------------------------------------------------------------------- | ---------------------------------- | --------------------------------------------------------------------------------- |
| `reset()` | Reset configuration to defaults | `.reset()` |
| `with_port(port)` | Add a port mapping | `.with_port("8080:80")` |
| `with_ports(ports_array)` | Add multiple port mappings | `.with_ports(["8080:80", "443:443"])` |
| `with_volume(volume)` | Add a volume mount | `.with_volume("/host/path:/container/path")` |
| `with_volumes(volumes_array)` | Add multiple volume mounts | `.with_volumes(["/host/path1:/container/path1", "/host/path2:/container/path2"])` |
| `with_env(key, value)` | Add an environment variable | `.with_env("NGINX_HOST", "localhost")` |
| `with_envs(env_map)` | Add multiple environment variables | `.with_envs(#{"KEY1": "value1", "KEY2": "value2"})` |
| `with_network(network)` | Set the network | `.with_network("bridge")` |
| `with_network_alias(alias)` | Add a network alias | `.with_network_alias("web-server")` |
| `with_network_aliases(aliases_array)` | Add multiple network aliases | `.with_network_aliases(["web-server", "http-service"])` |
| `with_cpu_limit(cpus)` | Set CPU limit | `.with_cpu_limit("1.0")` |
| `with_cpu_shares(shares)` | Set CPU shares | `.with_cpu_shares("1024")` |
| `with_memory_limit(memory)` | Set memory limit | `.with_memory_limit("512m")` |
| `with_memory_swap_limit(memory_swap)` | Set memory swap limit | `.with_memory_swap_limit("1g")` |
| `with_restart_policy(policy)` | Set restart policy | `.with_restart_policy("unless-stopped")` |
| `with_health_check(cmd)` | Set health check command | `.with_health_check("curl -f http://localhost/ | | exit 1")` |
| `with_health_check_options(cmd, interval, timeout, retries, start_period)` | Set health check with options | `.with_health_check_options("curl -f http://localhost/ | | exit 1", "5s", "3s", 3, "10s")` |
| `with_snapshotter(snapshotter)` | Set snapshotter | `.with_snapshotter("native")` |
| `with_detach(detach)` | Set detach mode | `.with_detach(true)` |
## Complete Example: Web Server
Here's a complete example that demonstrates setting up an Nginx web server using the Container Builder Pattern:
```rhai
// Create a temporary directory for our files
let work_dir = "/tmp/nerdctl";
mkdir(work_dir);
chdir(work_dir);
// Create a custom index.html file
let html_content = `
<!DOCTYPE html>
<html>
<head>
<title>Rhai Nerdctl Demo</title>
<style>
body {
font-family: Arial, sans-serif;
margin: 40px;
line-height: 1.6;
color: #333;
}
h1 {
color: #0066cc;
}
</style>
</head>
<body>
<h1>Hello from Rhai Nerdctl!</h1>
<p>This page is served by an Nginx container created using the Rhai nerdctl wrapper.</p>
</body>
</html>
`;
// Write the HTML file
let html_file = `${work_dir}/index.html`;
file_write(html_file, html_content);
// Set up environment variables
let env_map = #{};
env_map["NGINX_HOST"] = "localhost";
env_map["NGINX_PORT"] = "80";
env_map["NGINX_WORKER_PROCESSES"] = "auto";
// Create and configure the container
let container_name = "rhai-nginx-demo";
// First, try to remove any existing container with the same name
nerdctl_remove(container_name);
// Create a container with a rich set of options using the builder pattern
let container = nerdctl_container_from_image(container_name, "nginx:latest")
.reset() // Reset to default configuration
.with_detach(true)
.with_ports(["8080:80"]) // Add multiple ports at once
.with_volumes([`${work_dir}:/usr/share/nginx/html`]) // Mount our work dir
.with_envs(env_map) // Add multiple environment variables at once
.with_network("bridge")
.with_network_aliases(["web-server", "nginx-demo"]) // Add multiple network aliases
.with_cpu_limit("1.0")
.with_memory_limit("512m");
// Build and start the container
let built_container = container.build();
let start_result = built_container.start();
println("The web server is running at http://localhost:8080");
```
## Using Local Images Created with Buildah
When working with images created by Buildah, you may need to take additional steps to ensure nerdctl can find and use these images. This is because Buildah and nerdctl may use different storage backends by default.
### Tagging with localhost Prefix
One approach is to tag the Buildah-created image with a `localhost/` prefix:
```rhai
// Create and commit a container with Buildah
let builder = bah_new("my-container", "alpine:latest");
builder.run("echo 'Hello' > /hello.txt");
builder.commit("my-custom-image:latest");
// Tag the image with localhost prefix for nerdctl compatibility
let local_image_name = "localhost/my-custom-image:latest";
bah_image_tag("my-custom-image:latest", local_image_name);
// Now use the image with nerdctl
let container = nerdctl_container_from_image("my-app", local_image_name)
.with_detach(true)
.build();
```
### Using a Local Registry
For more reliable interoperability, you can push the image to a local registry:
```rhai
// Push the Buildah-created image to a local registry
bah_image_push("my-custom-image:latest", "localhost:5000/my-custom-image:latest", false);
// Pull the image with nerdctl
nerdctl_image_pull("localhost:5000/my-custom-image:latest");
// Use the image
let container = nerdctl_container_from_image("my-app", "localhost:5000/my-custom-image:latest")
.with_detach(true)
.build();
```
## Image Management Functions
The module also provides functions for managing container images:
| Function | Description | Example |
| --------------------------------------------- | --------------------------------------- | ------------------------------------------------------------------------------- |
| `nerdctl_images()` | List images in local storage | `nerdctl_images()` |
| `nerdctl_image_remove(image)` | Remove an image | `nerdctl_image_remove("nginx:latest")` |
| `nerdctl_image_push(image, destination)` | Push an image to a registry | `nerdctl_image_push("my-image:latest", "registry.example.com/my-image:latest")` |
| `nerdctl_image_tag(image, new_name)` | Add an additional name to a local image | `nerdctl_image_tag("nginx:latest", "my-nginx:latest")` |
| `nerdctl_image_pull(image)` | Pull an image from a registry | `nerdctl_image_pull("nginx:latest")` |
| `nerdctl_image_commit(container, image_name)` | Commit a container to an image | `nerdctl_image_commit("web-server", "my-nginx:latest")` |
| `nerdctl_image_build(tag, context_path)` | Build an image using a Dockerfile | `nerdctl_image_build("my-image:latest", "./")` |

# Process Module
The Process module provides functions for running commands and managing processes on your system.
## Command Results
### Command Output Information
When you run a command, you get back information about what happened:
- `stdout`: The normal output of the command
- `stderr`: Any error messages from the command
- `success`: Whether the command worked (true) or failed (false)
- `code`: The exit code (0 usually means success)
### Process Information
When you get information about a running process, you can see:
- `pid`: The process ID number
- `name`: The name of the process
- `memory`: How much memory the process is using
- `cpu`: How much CPU the process is using
## Run Functions
### `run(command)`
Runs a command or multiline script with arguments.
**Parameters:**
- `command` (string): The command to run (can be a single command or a multiline script)
**Returns:** The result of the command, including output and whether it succeeded.
**Example 1: Running a simple command**
```js
// Run a simple command
let result = run("ls -la");
// Check if the command was successful
if result.success {
print(`Command output: ${result.stdout}`);
} else {
print(`Command failed with error: ${result.stderr}`);
}
```
**Example 2: Running a multiline script**
```js
// Create a multiline script using backtick string literals
let setup_script = `
# Create directories
mkdir -p /tmp/test_project
cd /tmp/test_project
# Initialize git repository
git init
echo 'Initial content' > README.md
git add README.md
git config --local user.email 'test@example.com'
git config --local user.name 'Test User'
git commit -m 'Initial commit'
`;
// Execute the multiline script
let result = run(setup_script);
```
### `run_silent(command)`
Runs a command or multiline script with arguments silently (without displaying output).
**Parameters:**
- `command` (string): The command to run
**Returns:** The result of the command, without displaying the output.
**Example:**
```js
// Run a command silently
let result = run_silent("git pull");
// Check the exit code
if result.code == 0 {
print("Git pull successful");
} else {
print(`Git pull failed with code ${result.code}`);
}
```
### `new_run_options()`
Creates a new map with default run options.
**Returns:** A map with the following default options:
- `die` (boolean): `true` - Whether to throw an error if the command fails
- `silent` (boolean): `false` - Whether to suppress command output
- `async_exec` (boolean): `false` - Whether to run the command asynchronously
- `log` (boolean): `false` - Whether to log the command execution
**Example:**
```js
// Create run options
let options = new_run_options();
```
### `run_with_options(command, options)`
Runs a command with options specified in a map.
**Parameters:**
- `command` (string): The command to run
- `options` (map): A map of options created with `new_run_options()`
**Returns:** The result of the command with your custom settings applied.
**Example:**
```js
// Create and customize run options
let options = new_run_options();
options.die = false; // Don't throw an error if the command fails
options.silent = true; // Suppress command output
options.async_exec = false; // Run synchronously
options.log = true; // Log the command execution
// Run a command with options
let result = run_with_options("npm install", options);
```
## Working with Multiline Scripts
The Process module allows you to execute multiline scripts, which is particularly useful for complex operations that require multiple commands to be executed in sequence.
### Creating Multiline Scripts
Multiline scripts can be created using backtick (`) string literals in HeroScript:
```js
let my_script = `
# This is a multiline bash script
echo "Hello, World!"
mkdir -p /tmp/my_project
cd /tmp/my_project
touch example.txt
`;
```
## Process Management Functions
### `which(cmd)`
Checks if a command exists in the PATH.
**Parameters:**
- `cmd` (string): The command to check
**Returns:** The full path to the command if found, or nothing if not found.
**Example:**
```js
// Check if a command exists
let git_path = which("git");
if git_path != () {
print(`Git is installed at: ${git_path}`);
} else {
print("Git is not installed");
}
```
### `kill(pattern)`
Kills processes matching a pattern.
**Parameters:**
- `pattern` (string): The pattern to match process names against
**Returns:** A message confirming the processes were killed.
**Example:**
```js
// Kill all processes with "node" in their name
kill("node");
```
### `process_list(pattern)`
Lists processes matching a pattern (or all processes if the pattern is empty).
**Parameters:**
- `pattern` (string): The pattern to match process names against (can be empty to list all processes)
**Returns:** A list of processes matching your search.
**Example:**
```js
// List all processes
let all_processes = process_list("");
// List processes containing "node" in their name
let node_processes = process_list("node");
// Display process information
for process in node_processes {
print(`PID: ${process.pid}, Name: ${process.name}, Memory: ${process.memory}, CPU: ${process.cpu}`);
}
```
### `process_get(pattern)`
Gets a single process matching the pattern. Throws an error if zero or more than one process matches.
**Parameters:**
- `pattern` (string): The pattern to match process names against
**Returns:** Information about the matching process. This will only work if exactly one process matches.
**Example:**
```js
// Try to get a specific process
try {
let process = process_get("my_app");
print(`Found process: PID=${process.pid}, Name=${process.name}`);
} catch(err) {
print(`Error: ${err}`);
}
```

# RFS (Remote File System)
The RFS module provides a Rust wrapper for the RFS tool, which allows mounting remote filesystems locally and managing filesystem layers.
## Overview
RFS (Remote File System) is a tool that enables mounting various types of remote filesystems locally, as well as creating and managing filesystem layers. The SAL library provides a Rust wrapper for RFS with a fluent builder API, making it easy to use in your applications.
## Features
- Mount remote filesystems locally (SSH, S3, WebDAV, etc.)
- List mounted filesystems
- Unmount filesystems
- Pack directories into filesystem layers
- Unpack filesystem layers
- List contents of filesystem layers
- Verify filesystem layers
## Usage in Rust
### Mounting a Filesystem
```rust
use sal::virt::rfs::{RfsBuilder, MountType};
// Create a new RFS builder
let mount = RfsBuilder::new("user@example.com:/remote/path", "/local/mount/point", MountType::SSH)
.with_option("port", "2222")
.with_option("identity_file", "/path/to/key")
.with_debug(true)
.mount()?;
println!("Mounted filesystem with ID: {}", mount.id);
```
### Listing Mounts
```rust
use sal::virt::rfs::list_mounts;
// List all mounts
let mounts = list_mounts()?;
for mount in mounts {
println!("Mount ID: {}, Source: {}, Target: {}", mount.id, mount.source, mount.target);
}
```
### Unmounting a Filesystem
```rust
use sal::virt::rfs::unmount;
// Unmount a filesystem
unmount("/local/mount/point")?;
```
### Packing a Directory
```rust
use sal::virt::rfs::{PackBuilder, StoreSpec};
// Create store specifications
let store_spec = StoreSpec::new("file")
.with_option("path", "/path/to/store");
// Pack a directory with builder pattern
let result = PackBuilder::new("/path/to/directory", "output.fl")
.with_store_spec(store_spec)
.with_debug(true)
.pack()?;
```
### Unpacking a Filesystem Layer
```rust
use sal::virt::rfs::unpack;
// Unpack a filesystem layer
unpack("input.fl", "/path/to/unpack")?;
```
## Usage in Rhai Scripts
### Mounting a Filesystem
```rhai
// Create a map for mount options
let options = #{
"port": "22",
"identity_file": "/path/to/key",
"readonly": "true"
};
// Mount the directory
let mount = rfs_mount("user@example.com:/remote/path", "/local/mount/point", "ssh", options);
print(`Mounted ${mount.source} to ${mount.target} with ID: ${mount.id}`);
```
### Listing Mounts
```rhai
// List all mounts
let mounts = rfs_list_mounts();
print(`Number of mounts: ${mounts.len()}`);
for mount in mounts {
print(`Mount ID: ${mount.id}, Source: ${mount.source}, Target: ${mount.target}`);
}
```
### Unmounting a Filesystem
```rhai
// Unmount the directory
rfs_unmount("/local/mount/point");
```
### Packing a Directory
```rhai
// Pack the directory
// Store specs format: "file:path=/path/to/store,s3:bucket=my-bucket"
rfs_pack("/path/to/directory", "output.fl", "file:path=/path/to/store");
```
### Unpacking a Filesystem Layer
```rhai
// Unpack the filesystem layer
rfs_unpack("output.fl", "/path/to/unpack");
```
## Mount Types
The RFS module supports various mount types:
- **Local**: Mount a local directory
- **SSH**: Mount a remote directory via SSH
- **S3**: Mount an S3 bucket
- **WebDAV**: Mount a WebDAV server
## Store Specifications
When packing a directory into a filesystem layer, you can specify one or more stores to use. Each store has a type and options:
- **File**: Store files on the local filesystem
- Options: `path` (path to the store)
- **S3**: Store files in an S3 bucket
- Options: `bucket` (bucket name), `region` (AWS region), `access_key`, `secret_key`
## Examples
See the [RFS example script](../../rhaiexamples/rfs_example.rhai) for more examples of how to use the RFS module in Rhai scripts.

# Text Manipulation Tools
The SAL text module provides powerful text manipulation capabilities that can be used from Rhai scripts. These include text replacement (with regex support), template rendering, string normalization, and text formatting utilities.
## Table of Contents
- [Text Replacement](#text-replacement)
- [Template Rendering](#template-rendering)
- [String Normalization](#string-normalization)
- [Text Formatting](#text-formatting)
## Text Replacement
The text replacement tools allow you to perform simple or complex text replacements, with support for regular expressions, case-insensitive matching, and file operations.
### Basic Usage
```rhai
// Create a new text replacer
let replacer = text_replacer_new()
.pattern("foo") // Set the pattern to search for
.replacement("bar") // Set the replacement text
.build(); // Build the replacer
// Apply the replacer to a string
let result = replacer.replace("foo bar foo");
// Result: "bar bar bar"
```
### Advanced Features
#### Regular Expressions
```rhai
// Create a replacer with regex support
let replacer = text_replacer_new()
.pattern("\\bfoo\\b") // Use regex pattern (word boundary)
.replacement("bar")
.regex(true) // Enable regex mode
.build();
// Apply the replacer to a string
let result = replacer.replace("foo foobar");
// Result: "bar foobar" (only replaces whole "foo" words)
```
#### Case-Insensitive Matching
```rhai
// Create a replacer with case-insensitive matching
let replacer = text_replacer_new()
.pattern("foo")
.replacement("bar")
.regex(true)
.case_insensitive(true) // Enable case-insensitive matching
.build();
// Apply the replacer to a string
let result = replacer.replace("FOO foo Foo");
// Result: "bar bar bar"
```
#### Multiple Replacements
```rhai
// Chain multiple replacements
let replacer = text_replacer_new()
.pattern("foo")
.replacement("bar")
.and() // Add another replacement operation
.pattern("baz")
.replacement("qux")
.build();
// Apply the replacer to a string
let result = replacer.replace("foo baz");
// Result: "bar qux"
```
#### File Operations
```rhai
// Create a replacer
let replacer = text_replacer_new()
.pattern("foo")
.replacement("bar")
.build();
// Replace in a file and get the result as a string
let result = replacer.replace_file("input.txt");
// Replace in a file and write back to the same file
replacer.replace_file_in_place("input.txt");
// Replace in a file and write to a new file
replacer.replace_file_to("input.txt", "output.txt");
```
## Template Rendering
The template rendering tools allow you to create and render templates with variables, using the powerful Tera template engine.
### Basic Usage
```rhai
// Create a template builder with a template file
let template = template_builder_open("template.txt")
.add_var("name", "John") // Add a string variable
.add_var("age", 30) // Add a numeric variable
.add_var("items", ["a", "b", "c"]); // Add an array variable
// Render the template
let result = template.render();
// Render to a file
template.render_to_file("output.txt");
```
### Template Variables
You can add variables of various types:
```rhai
let template = template_builder_open("template.txt")
.add_var("name", "John") // String
.add_var("age", 30) // Integer
.add_var("height", 1.85) // Float
.add_var("is_active", true) // Boolean
.add_var("items", ["a", "b", "c"]); // Array
```
### Using Map for Variables
```rhai
// Create a map of variables
let vars = #{
name: "Alice",
place: "Wonderland"
};
// Add all variables from the map
let template = template_builder_open("template.txt")
.add_vars(vars);
```
### Template Syntax
The template engine uses Tera, which supports:
- Variable interpolation: `{{ variable }}`
- Conditionals: `{% if condition %}...{% endif %}`
- Loops: `{% for item in items %}...{% endfor %}`
- Filters: `{{ variable | filter }}`
Example template:
```
Hello, {{ name }}!
{% if show_greeting %}
Welcome to {{ place }}.
{% endif %}
Your items:
{% for item in items %}
- {{ item }}{% if not loop.last %}{% endif %}
{% endfor %}
```
## String Normalization
The string normalization tools help convert strings to consistent formats for use as file names or paths.
### name_fix
Converts a string to a safe, normalized name by:
- Converting to lowercase
- Replacing spaces and special characters with underscores
- Removing non-alphanumeric characters
```rhai
let fixed_name = name_fix("Hello World!");
// Result: "hello_world"
let fixed_name = name_fix("File-Name.txt");
// Result: "file_name.txt"
```
### path_fix
Similar to name_fix, but preserves path separators:
```rhai
let fixed_path = path_fix("/path/to/Hello World!");
// Result: "/path/to/hello_world"
let fixed_path = path_fix("./relative/path/to/DOCUMENT-123.pdf");
// Result: "./relative/path/to/document_123.pdf"
```
## Text Formatting
Tools to help with text formatting and indentation.
### dedent
Removes common leading whitespace from multi-line strings:
```rhai
let indented_text = " line 1
line 2
line 3";
let dedented = dedent(indented_text);
// Result: "line 1
// line 2
// line 3"
```
### prefix
Adds a prefix to every line in a multi-line string:
```rhai
let text = "line 1
line 2
line 3";
let prefixed = prefix(text, " ");
// Result: " line 1
// line 2
// line 3"
```
## Examples
See the [text_tools.rhai](https://github.com/ourworld-tf/herocode/blob/main/sal/src/rhaiexamples/text_tools.rhai) example script for more detailed examples of using these text manipulation tools.

# Git Interface Redesign Plan
## Current Understanding
The current git interface consists of standalone functions like `git_clone`, `git_list`, `git_update`, etc. We want to replace this with an object-oriented interface using a builder pattern that allows for method chaining.
## New Interface Design
### Core Components
```mermaid
classDiagram
class GitTree {
+String base_path
+new(base_path: &str) Result<GitTree, GitError>
+list() Result<Vec<String>, GitError>
+find(pattern: &str) Result<Vec<String>, GitError>
+get(path_pattern: &str) Result<Vec<GitRepo>, GitError>
}
class GitRepo {
+String path
+pull() Result<GitRepo, GitError>
+reset() Result<GitRepo, GitError>
+push() Result<GitRepo, GitError>
+commit(message: &str) Result<GitRepo, GitError>
+has_changes() Result<bool, GitError>
}
GitTree --> GitRepo : creates
```
### Implementation Details
1. **GitTree Class**:
- Constructor takes a base path parameter that specifies where all git repositories will be located
- Methods for listing and finding repositories
- A `get()` method that returns one or more GitRepo objects based on a path pattern
- The `get()` method can also accept a URL (git or http format) and will clone the repository if it doesn't exist
2. **GitRepo Class**:
- Represents a single git repository
- Methods for common git operations: pull, reset, push, commit
- Each method returns a Result containing either the GitRepo object (for chaining) or an error
- If an operation fails, subsequent operations in the chain are skipped
3. **Error Handling**:
- Each method returns a Result type for immediate error handling
- Errors are propagated up the call chain
- The existing GitError enum will be reused
## Implementation Plan
### 1. Create the GitTree and GitRepo Structs in git.rs
```rust
pub struct GitTree {
base_path: String,
}
pub struct GitRepo {
path: String,
}
```
### 2. Implement the GitTree Methods
```rust
impl GitTree {
pub fn new(base_path: &str) -> Result<Self, GitError> {
// Validate the base path
// Create the directory if it doesn't exist
Ok(GitTree {
base_path: base_path.to_string(),
})
}
pub fn list(&self) -> Result<Vec<String>, GitError> {
// List all git repositories under the base path
}
pub fn find(&self, pattern: &str) -> Result<Vec<String>, GitError> {
// Find repositories matching the pattern
}
pub fn get(&self, path_pattern: &str) -> Result<Vec<GitRepo>, GitError> {
// Find repositories matching the pattern
// Return GitRepo objects for each match
}
}
```
### 3. Implement the GitRepo Methods
```rust
impl GitRepo {
pub fn pull(&self) -> Result<Self, GitError> {
// Pull the latest changes
// Return self for chaining or an error
}
pub fn reset(&self) -> Result<Self, GitError> {
// Reset any local changes
// Return self for chaining or an error
}
pub fn push(&self) -> Result<Self, GitError> {
// Push changes to the remote
// Return self for chaining or an error
}
pub fn commit(&self, message: &str) -> Result<Self, GitError> {
// Commit changes with the given message
// Return self for chaining or an error
}
pub fn has_changes(&self) -> Result<bool, GitError> {
// Check if the repository has uncommitted changes
}
}
```
### 4. Update the Rhai Wrappers in rhai/git.rs
```rust
// Register the GitTree and GitRepo types with Rhai
pub fn register_git_module(engine: &mut Engine) -> Result<(), Box<EvalAltResult>> {
// Register the GitTree type
engine.register_type::<GitTree>();
engine.register_fn("new", git_tree_new);
// Register GitTree methods
engine.register_fn("list", git_tree_list);
engine.register_fn("find", git_tree_find);
engine.register_fn("get", git_tree_get);
// Register GitRepo methods
engine.register_type::<GitRepo>();
engine.register_fn("pull", git_repo_pull);
engine.register_fn("reset", git_repo_reset);
engine.register_fn("push", git_repo_push);
engine.register_fn("commit", git_repo_commit);
engine.register_fn("has_changes", git_repo_has_changes);
Ok(())
}
```
### 5. Update Tests and Examples
- Update the test files to use the new interface
- Create new examples demonstrating the builder pattern and method chaining
## Usage Examples
### Example 1: Basic Repository Operations
```rhai
// Create a new GitTree object
let git_tree = new("/home/user/code");
// List all repositories
let repos = git_tree.list();
print(`Found ${repos.len()} repositories`);
// Find repositories matching a pattern
let matching = git_tree.find("my-project*");
print(`Found ${matching.len()} matching repositories`);
// Get a repository and perform operations
let repo = git_tree.get("my-project")[0];
let result = repo.pull().reset().commit("Update files").push();
```
### Example 2: Working with Multiple Repositories
```rhai
// Create a new GitTree object
let git_tree = new("/home/user/code");
// Get all repositories matching a pattern
let repos = git_tree.get("project*");
print(`Found ${repos.len()} matching repositories`);
// Perform operations on all repositories
for repo in repos {
let result = repo.pull();
if result.is_ok() {
print(`Successfully pulled ${repo.path}`);
} else {
print(`Failed to pull ${repo.path}: ${result.error}`);
}
}
```
### Example 3: Cloning a Repository
```rhai
// Create a new GitTree object
let git_tree = new("/home/user/code");
// Clone a repository by URL
let repos = git_tree.get("https://github.com/username/repo.git");
let repo = repos[0];
print(`Repository cloned to: ${repo.path}`);
```
## Migration Strategy
1. Implement the new interface in git.rs and rhai/git.rs
2. Update all tests and examples to use the new interface
3. Remove the old standalone functions

# Package Management Module Implementation Plan
## Overview
The package management module will:
1. Provide a factory called `PackHero` that detects the current platform
2. Implement platform-specific package managers for Ubuntu (apt) and macOS (brew)
3. Support operations: install, remove, update, upgrade, list installed packages, search for packages, and check if a package is installed
4. Include debug functionality similar to buildah
5. Ensure all operations are non-interactive and have proper error propagation
6. Be wrapped in Rhai for scripting access
## Architecture

}
PackHero --> Platform : uses
PackHero --> PackageManager : uses
PackageManager <|.. AptPackageManager : implements
PackageManager <|.. BrewPackageManager : implements
```
## Implementation Details
### 1. Package Error Type
Create a custom error type for package management operations:
```rust
pub enum PackageError {
CommandFailed(String),
CommandExecutionFailed(std::io::Error),
UnsupportedPlatform(String),
Other(String),
}
```
### 2. Platform Detection
Implement platform detection to determine which package manager to use:
```rust
pub enum Platform {
Ubuntu,
MacOS,
Unknown,
}
impl Platform {
pub fn detect() -> Self {
// Check for macOS
if std::path::Path::new("/usr/bin/sw_vers").exists() {
return Platform::MacOS;
}
// Check for Ubuntu
if std::path::Path::new("/etc/lsb-release").exists() {
// Read the file to confirm it's Ubuntu
if let Ok(content) = std::fs::read_to_string("/etc/lsb-release") {
if content.contains("Ubuntu") {
return Platform::Ubuntu;
}
}
}
Platform::Unknown
}
}
```
### 3. Package Manager Trait
Define a trait for package managers to implement:
```rust
pub trait PackageManager {
fn install(&self, package: &str) -> Result<CommandResult, PackageError>;
fn remove(&self, package: &str) -> Result<CommandResult, PackageError>;
fn update(&self) -> Result<CommandResult, PackageError>;
fn upgrade(&self) -> Result<CommandResult, PackageError>;
fn list_installed(&self) -> Result<Vec<String>, PackageError>;
fn search(&self, query: &str) -> Result<Vec<String>, PackageError>;
fn is_installed(&self, package: &str) -> Result<bool, PackageError>;
}
```
### 4. Platform-Specific Implementations
#### Ubuntu (apt) Implementation
```rust
pub struct AptPackageManager {
debug: bool,
}
impl AptPackageManager {
pub fn new(debug: bool) -> Self {
Self { debug }
}
}
impl PackageManager for AptPackageManager {
fn install(&self, package: &str) -> Result<CommandResult, PackageError> {
execute_package_command(&["apt-get", "install", "-y", package], self.debug)
}
fn remove(&self, package: &str) -> Result<CommandResult, PackageError> {
execute_package_command(&["apt-get", "remove", "-y", package], self.debug)
}
fn update(&self) -> Result<CommandResult, PackageError> {
execute_package_command(&["apt-get", "update", "-y"], self.debug)
}
fn upgrade(&self) -> Result<CommandResult, PackageError> {
execute_package_command(&["apt-get", "upgrade", "-y"], self.debug)
}
fn list_installed(&self) -> Result<Vec<String>, PackageError> {
let result = execute_package_command(&["dpkg", "--get-selections"], self.debug)?;
let packages = result.stdout
.lines()
.filter_map(|line| {
let parts: Vec<&str> = line.split_whitespace().collect();
if parts.len() >= 2 && parts[1] == "install" {
Some(parts[0].to_string())
} else {
None
}
})
.collect();
Ok(packages)
}
fn search(&self, query: &str) -> Result<Vec<String>, PackageError> {
let result = execute_package_command(&["apt-cache", "search", query], self.debug)?;
let packages = result.stdout
.lines()
.map(|line| {
let parts: Vec<&str> = line.split_whitespace().collect();
if !parts.is_empty() {
parts[0].to_string()
} else {
String::new()
}
})
.filter(|s| !s.is_empty())
.collect();
Ok(packages)
}
fn is_installed(&self, package: &str) -> Result<bool, PackageError> {
let result = execute_package_command(&["dpkg", "-s", package], self.debug);
match result {
Ok(cmd_result) => Ok(cmd_result.success),
Err(_) => Ok(false),
}
}
}
```
#### macOS (brew) Implementation
```rust
pub struct BrewPackageManager {
debug: bool,
}
impl BrewPackageManager {
pub fn new(debug: bool) -> Self {
Self { debug }
}
}
impl PackageManager for BrewPackageManager {
fn install(&self, package: &str) -> Result<CommandResult, PackageError> {
execute_package_command(&["brew", "install", package], self.debug)
}
fn remove(&self, package: &str) -> Result<CommandResult, PackageError> {
execute_package_command(&["brew", "uninstall", package], self.debug)
}
fn update(&self) -> Result<CommandResult, PackageError> {
execute_package_command(&["brew", "update"], self.debug)
}
fn upgrade(&self) -> Result<CommandResult, PackageError> {
execute_package_command(&["brew", "upgrade"], self.debug)
}
fn list_installed(&self) -> Result<Vec<String>, PackageError> {
let result = execute_package_command(&["brew", "list", "--formula"], self.debug)?;
let packages = result.stdout
.lines()
.map(|line| line.trim().to_string())
.filter(|s| !s.is_empty())
.collect();
Ok(packages)
}
fn search(&self, query: &str) -> Result<Vec<String>, PackageError> {
let result = execute_package_command(&["brew", "search", query], self.debug)?;
let packages = result.stdout
.lines()
.map(|line| line.trim().to_string())
.filter(|s| !s.is_empty())
.collect();
Ok(packages)
}
fn is_installed(&self, package: &str) -> Result<bool, PackageError> {
let result = execute_package_command(&["brew", "list", package], self.debug);
match result {
Ok(cmd_result) => Ok(cmd_result.success),
Err(_) => Ok(false),
}
}
}
```
### 5. Command Execution with Debug Support
Implement a function to execute package management commands with debug support:
```rust
// Thread-local storage for debug flag
thread_local! {
static DEBUG: std::cell::RefCell<bool> = std::cell::RefCell::new(false);
}
/// Set the debug flag for the current thread
pub fn set_thread_local_debug(debug: bool) {
DEBUG.with(|cell| {
*cell.borrow_mut() = debug;
});
}
/// Get the debug flag for the current thread
pub fn thread_local_debug() -> bool {
DEBUG.with(|cell| {
*cell.borrow()
})
}
/// Execute a package management command and return the result
pub fn execute_package_command(args: &[&str], debug: bool) -> Result<CommandResult, PackageError> {
// Save the current debug flag
let previous_debug = thread_local_debug();
// Set the thread-local debug flag
set_thread_local_debug(debug);
if debug {
println!("Executing command: {}", args.join(" "));
}
let output = Command::new(args[0])
.args(&args[1..])
.output();
// Restore the previous debug flag
set_thread_local_debug(previous_debug);
match output {
Ok(output) => {
let stdout = String::from_utf8_lossy(&output.stdout).to_string();
let stderr = String::from_utf8_lossy(&output.stderr).to_string();
let result = CommandResult {
stdout,
stderr,
success: output.status.success(),
code: output.status.code().unwrap_or(-1),
};
// Always output stdout/stderr when debug is true
if debug {
if !result.stdout.is_empty() {
println!("Command stdout: {}", result.stdout);
}
if !result.stderr.is_empty() {
println!("Command stderr: {}", result.stderr);
}
if result.success {
println!("Command succeeded with code {}", result.code);
} else {
println!("Command failed with code {}", result.code);
}
}
if result.success {
Ok(result)
} else {
// If command failed and debug is false, output stderr
if !debug {
println!("Command failed with code {}: {}", result.code, result.stderr.trim());
}
Err(PackageError::CommandFailed(format!("Command failed with code {}: {}",
result.code, result.stderr.trim())))
}
},
Err(e) => {
// Always output error information
println!("Command execution failed: {}", e);
Err(PackageError::CommandExecutionFailed(e))
}
}
}
```
### 6. PackHero Factory
Implement the PackHero factory to provide a unified interface:
```rust
pub struct PackHero {
platform: Platform,
debug: bool,
}
impl PackHero {
pub fn new() -> Self {
let platform = Platform::detect();
Self {
platform,
debug: false,
}
}
pub fn set_debug(&mut self, debug: bool) -> &mut Self {
self.debug = debug;
self
}
pub fn debug(&self) -> bool {
self.debug
}
fn get_package_manager(&self) -> Result<Box<dyn PackageManager>, PackageError> {
match self.platform {
Platform::Ubuntu => Ok(Box::new(AptPackageManager::new(self.debug))),
Platform::MacOS => Ok(Box::new(BrewPackageManager::new(self.debug))),
Platform::Unknown => Err(PackageError::UnsupportedPlatform("Unsupported platform".to_string())),
}
}
pub fn install(&self, package: &str) -> Result<CommandResult, PackageError> {
let pm = self.get_package_manager()?;
pm.install(package)
}
pub fn remove(&self, package: &str) -> Result<CommandResult, PackageError> {
let pm = self.get_package_manager()?;
pm.remove(package)
}
pub fn update(&self) -> Result<CommandResult, PackageError> {
let pm = self.get_package_manager()?;
pm.update()
}
pub fn upgrade(&self) -> Result<CommandResult, PackageError> {
let pm = self.get_package_manager()?;
pm.upgrade()
}
pub fn list_installed(&self) -> Result<Vec<String>, PackageError> {
let pm = self.get_package_manager()?;
pm.list_installed()
}
pub fn search(&self, query: &str) -> Result<Vec<String>, PackageError> {
let pm = self.get_package_manager()?;
pm.search(query)
}
pub fn is_installed(&self, package: &str) -> Result<bool, PackageError> {
let pm = self.get_package_manager()?;
pm.is_installed(package)
}
}
```
### 7. Rhai Integration
Update the Rhai OS module to include the package management functions:
```rust
// In rhai/os.rs
// Register package management functions
engine.register_fn("package_install", package_install);
engine.register_fn("package_remove", package_remove);
engine.register_fn("package_update", package_update);
engine.register_fn("package_upgrade", package_upgrade);
engine.register_fn("package_list", package_list);
engine.register_fn("package_search", package_search);
engine.register_fn("package_is_installed", package_is_installed);
engine.register_fn("package_set_debug", package_set_debug);
// Wrapper for os::package::install
pub fn package_install(package: &str) -> Result<String, Box<EvalAltResult>> {
let hero = os::package::PackHero::new();
hero.install(package)
.map(|_| "Package installed successfully".to_string())
.to_rhai_error()
}
// Wrapper for os::package::remove
pub fn package_remove(package: &str) -> Result<String, Box<EvalAltResult>> {
let hero = os::package::PackHero::new();
hero.remove(package)
.map(|_| "Package removed successfully".to_string())
.to_rhai_error()
}
// Wrapper for os::package::update
pub fn package_update() -> Result<String, Box<EvalAltResult>> {
let hero = os::package::PackHero::new();
hero.update()
.map(|_| "Package lists updated successfully".to_string())
.to_rhai_error()
}
// Wrapper for os::package::upgrade
pub fn package_upgrade() -> Result<String, Box<EvalAltResult>> {
let hero = os::package::PackHero::new();
hero.upgrade()
.map(|_| "Packages upgraded successfully".to_string())
.to_rhai_error()
}
// Wrapper for os::package::list_installed
pub fn package_list() -> Result<Array, Box<EvalAltResult>> {
let hero = os::package::PackHero::new();
let packages = hero.list_installed().to_rhai_error()?;
// Convert Vec<String> to Rhai Array
let mut array = Array::new();
for package in packages {
array.push(package.into());
}
Ok(array)
}
// Wrapper for os::package::search
pub fn package_search(query: &str) -> Result<Array, Box<EvalAltResult>> {
let hero = os::package::PackHero::new();
let packages = hero.search(query).to_rhai_error()?;
// Convert Vec<String> to Rhai Array
let mut array = Array::new();
for package in packages {
array.push(package.into());
}
Ok(array)
}
// Wrapper for os::package::is_installed
pub fn package_is_installed(package: &str) -> Result<bool, Box<EvalAltResult>> {
let hero = os::package::PackHero::new();
hero.is_installed(package).to_rhai_error()
}
// Global debug flag for package management
static mut PACKAGE_DEBUG: bool = false;
// Wrapper for setting package debug mode
pub fn package_set_debug(debug: bool) -> bool {
unsafe {
PACKAGE_DEBUG = debug;
PACKAGE_DEBUG
}
}
```
## Implementation Steps
1. Create the package.rs file in the os directory
2. Implement the PackageError enum
3. Implement the Platform enum with detection logic
4. Implement the PackageManager trait
5. Implement the AptPackageManager for Ubuntu
6. Implement the BrewPackageManager for macOS
7. Implement the debug functionality with thread-local storage
8. Implement the PackHero factory
9. Update os/mod.rs to include the package module
10. Update rhai/os.rs to include the package management functions
11. Test the implementation on both Ubuntu and macOS
## Testing Strategy
1. Create unit tests for each platform-specific implementation
2. Create integration tests that verify the PackHero factory correctly detects the platform and uses the appropriate package manager
3. Create Rhai examples that demonstrate the use of the package management functions

# Implementation Plan: Rhai Wrappers for Text Tools
## 1. Overview
We'll create a new module `rhai/text.rs` that will provide Rhai wrappers for all functionality in the text module, including:
- TextReplacer (from replace.rs)
- TemplateBuilder (from template.rs)
- name_fix and path_fix functions (from fix.rs)
- dedent and prefix functions (from dedent.rs)
The implementation will follow the builder pattern for the TextReplacer and TemplateBuilder classes, similar to their Rust implementations, and will use the same error handling pattern as the existing Rhai modules.
## 2. Module Structure
```mermaid
graph TD
A[rhai/mod.rs] --> B[rhai/text.rs]
B --> C[TextReplacer Wrappers]
B --> D[TemplateBuilder Wrappers]
B --> E[Fix Function Wrappers]
B --> F[Dedent Function Wrappers]
B --> G[Error Handling]
B --> H[Registration Functions]
```
## 3. Implementation Details
### 3.1. Module Setup and Registration
1. Create a new file `rhai/text.rs`
2. Add the module to `rhai/mod.rs`
3. Implement a `register_text_module` function to register all text-related functions with the Rhai engine
4. Update the main `register` function in `rhai/mod.rs` to call `register_text_module`
### 3.2. TextReplacer Implementation
1. Register the TextReplacer type with the Rhai engine
2. Implement the following functions:
- `text_replacer_new()` - Creates a new TextReplacerBuilder
- `pattern(builder, pat)` - Sets the pattern to search for and automatically adds any previous pattern/replacement pair to the chain
- `replacement(builder, rep)` - Sets the replacement text
- `regex(builder, yes)` - Sets whether to use regex
- `case_insensitive(builder, yes)` - Sets whether the replacement should be case-insensitive
- `build(builder)` - Builds the TextReplacer with all configured replacement operations
- `replace(replacer, input)` - Applies all configured replacement operations to the input text
- `replace_file(replacer, path)` - Reads a file, applies all replacements, and returns the result as a string
- `replace_file_in_place(replacer, path)` - Reads a file, applies all replacements, and writes the result back to the file
- `replace_file_to(replacer, input_path, output_path)` - Reads a file, applies all replacements, and writes the result to a new file
### 3.3. TemplateBuilder Implementation
1. Register the TemplateBuilder type with the Rhai engine
2. Implement the following functions:
- `template_builder_open(template_path)` - Creates a new TemplateBuilder with the specified template path
- `add_var(builder, name, value)` - Adds a variable to the template context
- `add_vars(builder, vars_map)` - Adds multiple variables to the template context from a Map
- `render(builder)` - Renders the template with the current context
- `render_to_file(builder, output_path)` - Renders the template and writes the result to a file
### 3.4. Fix Functions Implementation
1. Implement wrappers for the following functions:
- `name_fix(text)` - Sanitizes a name by replacing special characters with underscores
- `path_fix(text)` - Applies name_fix to the filename part of a path
### 3.5. Dedent Functions Implementation
1. Implement wrappers for the following functions:
- `dedent(text)` - Removes common leading whitespace from a multiline string
- `prefix(text, prefix)` - Adds a prefix to each line of a multiline string
### 3.6. Error Handling
1. Implement helper functions to convert Rust errors to Rhai errors:
- `io_error_to_rhai_error` - Converts io::Error to EvalAltResult
- `tera_error_to_rhai_error` - Converts tera::Error to EvalAltResult
- `string_error_to_rhai_error` - Converts String error to EvalAltResult
## 4. Example Usage in Rhai Scripts
### TextReplacer Example
```rhai
// Create a TextReplacer with multiple replacements
let replacer = text_replacer_new()
.pattern("foo").replacement("bar").regex(true)
.pattern("hello").replacement("world")
.build();
// Use the replacer
let result = replacer.replace("foo hello foo");
println(result); // Outputs: "bar world bar"
// Replace in a file
let file_result = replacer.replace_file("input.txt");
println(file_result);
// Replace and write to a new file
replacer.replace_file_to("input.txt", "output.txt");
```
### TemplateBuilder Example
```rhai
// Create a TemplateBuilder
let template = template_builder_open("template.txt")
.add_var("name", "John")
.add_var("age", 30)
.add_var("items", ["apple", "banana", "cherry"]);
// Render the template
let result = template.render();
println(result);
// Render to a file
template.render_to_file("output.html");
```
### Fix and Dedent Examples
```rhai
// Use name_fix and path_fix
let fixed_name = name_fix("Hello World!");
println(fixed_name); // Outputs: "hello_world"
let fixed_path = path_fix("/path/to/Hello World!");
println(fixed_path); // Outputs: "/path/to/hello_world"
// Use dedent and prefix
let indented_text = " line 1\n line 2\n line 3";
let dedented = dedent(indented_text);
println(dedented); // Outputs: "line 1\nline 2\n line 3"
let text = "line 1\nline 2\nline 3";
let prefixed = prefix(text, " ");
println(prefixed); // Outputs: " line 1\n line 2\n line 3"

## ✅ Step-by-step: Connect Rust to containerd via gRPC
CREATE A rhai script executing the following instructions below
use all rhai script features we have + give priority to what functions we have defined in /src/docs/docs/sal in this repo
---
### 1. 🧱 Install Dependencies
Add this to your `Cargo.toml`:
```toml
[dependencies]
tonic = "0.11"
prost = "0.12"
tokio = { version = "1", features = ["full"] }
[build-dependencies]
tonic-build = "0.11"
```
---
### 2. 📁 Clone containerd's gRPC proto files
```bash
git clone https://github.com/containerd/containerd.git
cd containerd
```
Containerd's API protos are in:
```
api/services/ # gRPC service definitions
api/types/ # message types
```
---
### 3. 📦 Set up `build.rs` to compile protos
In your Rust project root, create a `build.rs` file:
```rust
fn main() {
tonic_build::configure()
.build_server(false)
.compile(
&[
"containerd/api/services/images/v1/images.proto",
"containerd/api/services/containers/v1/containers.proto",
// Add more proto files as needed
],
&[
"containerd/api",
"containerd/api/types"
],
)
.unwrap();
}
```
Make sure to place the `containerd` directory somewhere your build can see — for example, symlink it or move it into your project as `proto/containerd`.
---
### 4. 🧪 Example: Connect to containerd's image service
After `build.rs` compiles the protos, your code can access them like this:
```rust
use tonic::transport::Channel;
use containerd::services::images::v1::{
images_client::ImagesClient,
GetImageRequest,
};
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Connect to containerd's gRPC socket (default path)
let channel = Channel::from_static("http://[::]:50051") // placeholder
.connect()
.await?;
let mut client = ImagesClient::new(channel);
let response = client.get(GetImageRequest {
name: "docker.io/library/ubuntu:latest".to_string(),
}).await?;
println!("Image: {:?}", response.into_inner());
Ok(())
}
```
🔧 Note: containerd uses a **Unix socket**, so replace the channel connection with:
```rust
use tonic::transport::{Endpoint, Uri};
use tower::service_fn;
use hyper_unix_connector::UnixConnector;
let uds = tokio::net::UnixStream::connect("/run/containerd/containerd.sock").await?;
let channel = Endpoint::try_from("http://[::]:50051")?
.connect_with_connector(service_fn(move |_| async move {
Ok::<_, std::io::Error>(uds)
}))
.await?;
```
(We can wrap that part into a helper if you want.)
---
### 5. 🔁 Rebuild the project
Each time you add or change a `.proto`, rebuild to regenerate code:
```bash
cargo clean && cargo build
```

@ -8,7 +8,6 @@ This module provides functions for text manipulation tasks such as:
- Removing indentation from multiline strings
- Adding prefixes to multiline strings
- Normalizing filenames and paths
- Text replacement (regex and literal) with file operations
## Functions
@ -69,86 +68,12 @@ assert_eq!(path_fix("./relative/path/to/DOCUMENT-123.pdf"), "./relative/path/to/
- Only normalizes the filename portion, leaving the path structure intact
- Handles both absolute and relative paths
### Text Replacement
#### `TextReplacer`
A flexible text replacement utility that supports both regex and literal replacements with a builder pattern.
```rust
// Regex replacement
let replacer = TextReplacer::builder()
.pattern(r"\bfoo\b")
.replacement("bar")
.regex(true)
.add_replacement()
.unwrap()
.build()
.unwrap();
let result = replacer.replace("foo bar foo baz"); // "bar bar bar baz"
```
**Features:**
- Supports both regex and literal string replacements
- Builder pattern for fluent configuration
- Multiple replacements in a single pass
- Case-insensitive matching (for regex replacements)
- File reading and writing operations
#### Multiple Replacements
```rust
let replacer = TextReplacer::builder()
.pattern("foo")
.replacement("qux")
.add_replacement()
.unwrap()
.pattern("bar")
.replacement("baz")
.add_replacement()
.unwrap()
.build()
.unwrap();
let result = replacer.replace("foo bar foo"); // "qux baz qux"
```
#### File Operations
```rust
// Replace in a file and get the result as a string
let result = replacer.replace_file("input.txt")?;
// Replace in a file and write back to the same file
replacer.replace_file_in_place("input.txt")?;
// Replace in a file and write to a new file
replacer.replace_file_to("input.txt", "output.txt")?;
```
#### Case-Insensitive Matching
```rust
let replacer = TextReplacer::builder()
.pattern("foo")
.replacement("bar")
.regex(true)
.case_insensitive(true)
.add_replacement()
.unwrap()
.build()
.unwrap();
let result = replacer.replace("FOO foo Foo"); // "bar bar bar"
```
## Usage
Import the functions from the module:
```rust
use your_crate::text::{dedent, prefix, name_fix, path_fix, TextReplacer};
use your_crate::text::{dedent, prefix, name_fix, path_fix};
```

# Container API for nerdctl
This module provides a Rust API for managing containers using nerdctl, a Docker-compatible CLI for containerd.
## Overview
The Container API is designed with a builder pattern to make it easy to create and manage containers. It provides a fluent interface for configuring container options and performing operations on containers.
## Key Components
- `Container`: The main struct representing a container
- `HealthCheck`: Configuration for container health checks
- `ContainerStatus`: Information about a container's status
- `ResourceUsage`: Information about a container's resource usage
## Getting Started
### Prerequisites
- nerdctl must be installed on your system
- containerd must be running
### Basic Usage
Add the following to your `Cargo.toml`:
```toml
[dependencies]
sal = { path = "/path/to/sal" }
```
Then import the Container API in your Rust code:
```rust
use sal::virt::nerdctl::Container;
```
## Usage Examples
### Getting a Container by Name
You can get a reference to an existing container by name:
```rust
use sal::virt::nerdctl::Container;
// Get a container by name (if it exists)
match Container::new("existing-container") {
Ok(container) => {
if container.container_id.is_some() {
println!("Found container with ID: {}", container.container_id.unwrap());
// Perform operations on the existing container
let status = container.status()?;
println!("Container status: {}", status.status);
} else {
println!("Container exists but has no ID");
}
},
Err(e) => {
println!("Error getting container: {}", e);
}
}
```
### Creating a Container
You can create a new container from an image using the builder pattern:
```rust
use sal::virt::nerdctl::Container;
// Create a container from an image
let container = Container::from_image("my-nginx", "nginx:latest")?
.with_port("8080:80")
.with_env("NGINX_HOST", "example.com")
.with_volume("/tmp/nginx:/usr/share/nginx/html")
.with_health_check("curl -f http://localhost/ || exit 1")
.with_detach(true)
.build()?;
```
### Container Operations
Once you have a container, you can perform various operations on it:
```rust
// Execute a command in the container
let result = container.exec("echo 'Hello from container'")?;
println!("Command output: {}", result.stdout);
// Get container status
let status = container.status()?;
println!("Container status: {}", status.status);
// Get resource usage
let resources = container.resources()?;
println!("CPU usage: {}", resources.cpu_usage);
println!("Memory usage: {}", resources.memory_usage);
// Stop and remove the container
container.stop()?;
container.remove()?;
```
## Container Configuration Options
The Container API supports a wide range of configuration options through its builder pattern:
### Ports
Map container ports to host ports:
```rust
// Map a single port
.with_port("8080:80")
// Map multiple ports
.with_ports(&["8080:80", "8443:443"])
```
### Volumes
Mount host directories or volumes in the container:
```rust
// Mount a single volume
.with_volume("/host/path:/container/path")
// Mount multiple volumes
.with_volumes(&["/host/path1:/container/path1", "/host/path2:/container/path2"])
```
### Environment Variables
Set environment variables in the container:
```rust
// Set a single environment variable
.with_env("KEY", "value")
// Set multiple environment variables
let mut env_map = HashMap::new();
env_map.insert("KEY1", "value1");
env_map.insert("KEY2", "value2");
.with_envs(&env_map)
```
### Network Configuration
Configure container networking:
```rust
// Set the network
.with_network("bridge")
// Add a network alias
.with_network_alias("my-container")
// Add multiple network aliases
.with_network_aliases(&["alias1", "alias2"])
```
### Resource Limits
Set CPU and memory limits:
```rust
// Set CPU limit (e.g., 0.5 for half a CPU, 2 for 2 CPUs)
.with_cpu_limit("0.5")
// Set memory limit (e.g., 512m for 512MB, 1g for 1GB)
.with_memory_limit("512m")
// Set memory swap limit
.with_memory_swap_limit("1g")
// Set CPU shares (relative weight)
.with_cpu_shares("1024")
```
### Health Checks
Configure container health checks:
```rust
// Simple health check
.with_health_check("curl -f http://localhost/ || exit 1")
// Health check with custom options
.with_health_check_options(
"curl -f http://localhost/ || exit 1", // Command
Some("30s"), // Interval
Some("10s"), // Timeout
Some(3), // Retries
Some("5s") // Start period
)
```
### Other Options
Other container configuration options:
```rust
// Set restart policy
.with_restart_policy("always") // Options: no, always, on-failure, unless-stopped
// Set snapshotter
.with_snapshotter("native") // Options: native, fuse-overlayfs, etc.
// Set detach mode
.with_detach(true) // Run in detached mode
```
## Container Operations
Once a container is created, you can perform various operations on it:
### Basic Operations
```rust
// Start the container
container.start()?;
// Stop the container
container.stop()?;
// Remove the container
container.remove()?;
```
### Command Execution
```rust
// Execute a command in the container
let result = container.exec("echo 'Hello from container'")?;
println!("Command output: {}", result.stdout);
```
### File Operations
```rust
// Copy files between the container and host
container.copy("container_name:/path/in/container", "/path/on/host")?;
container.copy("/path/on/host", "container_name:/path/in/container")?;
// Export the container to a tarball
container.export("/path/to/export.tar")?;
```
### Image Operations
```rust
// Commit the container to an image
container.commit("my-custom-image:latest")?;
```
### Status and Monitoring
```rust
// Get container status
let status = container.status()?;
println!("Container state: {}", status.state);
println!("Container status: {}", status.status);
println!("Created: {}", status.created);
println!("Started: {}", status.started);
// Get health status
let health_status = container.health_status()?;
println!("Health status: {}", health_status);
// Get resource usage
let resources = container.resources()?;
println!("CPU usage: {}", resources.cpu_usage);
println!("Memory usage: {}", resources.memory_usage);
println!("Memory limit: {}", resources.memory_limit);
println!("Memory percentage: {}", resources.memory_percentage);
println!("Network I/O: {} / {}", resources.network_input, resources.network_output);
println!("Block I/O: {} / {}", resources.block_input, resources.block_output);
println!("PIDs: {}", resources.pids);
```
## Error Handling
The Container API uses a custom error type `NerdctlError` that can be one of the following:
- `CommandExecutionFailed`: The nerdctl command failed to execute
- `CommandFailed`: The nerdctl command executed but returned an error
- `JsonParseError`: Failed to parse JSON output
- `ConversionError`: Failed to convert data
- `Other`: Generic error
Example error handling:
```rust
match Container::new("non-existent-container") {
Ok(container) => {
// Container exists
println!("Container found");
},
Err(e) => {
match e {
NerdctlError::CommandExecutionFailed(io_error) => {
println!("Failed to execute nerdctl command: {}", io_error);
},
NerdctlError::CommandFailed(error_msg) => {
println!("nerdctl command failed: {}", error_msg);
},
_ => {
println!("Other error: {}", e);
}
}
}
}
```
## Implementation Details
The Container API is implemented in several modules:
- `container_types.rs`: Contains the struct definitions
- `container.rs`: Contains the main Container implementation
- `container_builder.rs`: Contains the builder pattern methods
- `container_operations.rs`: Contains the container operations
- `health_check.rs`: Contains the HealthCheck implementation
This modular approach makes the code more maintainable and easier to understand.
## Complete Example
Here's a complete example that demonstrates the Container API:
```rust
use std::error::Error;
use sal::virt::nerdctl::Container;
fn main() -> Result<(), Box<dyn Error>> {
// Create a container from an image
println!("Creating container from image...");
let container = Container::from_image("my-nginx", "nginx:latest")?
.with_port("8080:80")
.with_env("NGINX_HOST", "example.com")
.with_volume("/tmp/nginx:/usr/share/nginx/html")
.with_health_check("curl -f http://localhost/ || exit 1")
.with_detach(true)
.build()?;
println!("Container created successfully");
// Execute a command in the container
println!("Executing command in container...");
let result = container.exec("echo 'Hello from container'")?;
println!("Command output: {}", result.stdout);
// Get container status
println!("Getting container status...");
let status = container.status()?;
println!("Container status: {}", status.status);
// Get resource usage
println!("Getting resource usage...");
let resources = container.resources()?;
println!("CPU usage: {}", resources.cpu_usage);
println!("Memory usage: {}", resources.memory_usage);
// Stop and remove the container
println!("Stopping and removing container...");
container.stop()?;
container.remove()?;
println!("Container stopped and removed");
Ok(())
