# Oak ActionScript Parser
[](https://crates.io/crates/oak-actionscript)
[](https://docs.rs/oak-actionscript)
High-performance incremental ActionScript parser for the oak ecosystem with flexible configuration, optimized for Adobe Flash and Apache Flex development.
## 🎯 Overview
Oak ActionScript is a robust parser for ActionScript 3.0, designed to handle both legacy Flash and modern Flex applications. Built on the solid foundation of oak-core, it provides both high-level convenience and detailed AST generation for ActionScript analysis and tooling.
## ✨ Features
- **Complete AS3 Syntax**: Supports all ActionScript 3.0 features including modern specifications
- **Full AST Generation**: Generates comprehensive Abstract Syntax Trees
- **Lexer Support**: Built-in tokenization with proper span information
- **Error Recovery**: Graceful handling of syntax errors with detailed diagnostics
## 🚀 Quick Start
Basic example:
```rust
use oak_actionscript::{Parser, ActionScriptLanguage, SourceText};
fn main() -> Result<(), Box<dyn std::error::Error>> {
let parser = Parser::new();
let source = SourceText::new(r#"
package com.example {
public class Main {
public function Main() {
trace("Hello, ActionScript!");
}
}
}
"#);
let result = parser.parse(&source);
println!("Parsed ActionScript package successfully.");
Ok(())
}
```
## 📋 Parsing Examples
### Class Parsing
```rust
use oak_actionscript::{Parser, ActionScriptLanguage, SourceText};
let parser = Parser::new();
let source = SourceText::new(r#"
public class MovieClip extends flash.display.MovieClip {
private var frameCount:int;
public function MovieClip() {
frameCount = 0;
}
public function play():void {
super.play();
}
}
"#);
let result = parser.parse(&source);
println!("Parsed ActionScript class successfully.");
```
### Function Parsing
```rust
use oak_actionscript::{Parser, ActionScriptLanguage, SourceText};
let parser = Parser::new();
let source = SourceText::new(r#"
public function calculateArea(width:Number, height:Number):Number {
return width * height;
}
"#);
let result = parser.parse(&source);
println!("Parsed ActionScript function successfully.");
```
## 🔧 Advanced Features
### Token-Level Parsing
```rust
use oak_actionscript::{Parser, ActionScriptLanguage, SourceText};
let parser = Parser::new();
let source = SourceText::new("public function test():void {}");
let result = parser.parse(&source);
// Token information is available in the parse result
```
### Error Handling
```rust
use oak_actionscript::{Parser, ActionScriptLanguage, SourceText};
let parser = Parser::new();
let source = SourceText::new(r#"
package {
public class Test {
public function test( {
trace("Missing closing parenthesis");
}
}
}
"#);
let result = parser.parse(&source);
if let Err(e) = result.result {
println!("Parse error: {:?}", e);
}
```
## 🏗️ AST Structure
The parser generates a comprehensive AST with the following main structures:
- **Package**: ActionScript package declarations
- **ClassDefinition**: Class definitions with inheritance
- **FunctionDefinition**: Function and method definitions
- **VariableDeclaration**: Variable declarations with type annotations
- **Expression**: Expressions including arithmetic, logical, and function calls
- **Statement**: Control flow statements and assignments
- **TypeAnnotation**: Type specifications and annotations
## 📊 Performance
- **Streaming**: Parse large ActionScript files without loading entirely into memory
- **Incremental**: Re-parse only changed sections
- **Memory Efficient**: Smart AST node allocation
- **Fast Recovery**: Quick error recovery for better IDE integration
## 🔗 Integration
Oak of actionscript integrates seamlessly with:
- **Flash Development**: Build Flash applications and games
- **Code Analysis**: Static analysis and refactoring tools
- **IDE Support**: Language server protocol compatibility for ActionScript
- **Migration Tools**: Convert ActionScript to other languages
- **Educational Tools**: Build programming language learning environments
