You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: transformer.rs
    path of file: ./repos/oxc/crates/oxc_transformer/examples
    
    the code of the file until where you have to start completion: use std::{
 
    
fn main() {
    let name = env::args().nth(1).unwrap_or_else(|| "test.tsx".to_string());
    let path = Path::new(&name);
    let source_text = std::fs::read_to_string(path).expect("{name} not found");
    let allocator = Allocator::default();
    let source_type = SourceType::from_path(path).unwrap();

    let ret = Parser::new(&allocator, &source_text, source_type).parse();

    if !ret.errors.is_empty() {
        for error in ret.errors {
            let error = error.with_source_code(source_text.clone());
            println!("{error:?}");
        }
        return;
    }

    println!("Original:\n");
    println!("{source_text}\n");

    let semantic = SemanticBuilder::new(&source_text, source_type)
        .with_trivias(ret.trivias)
        .build_module_record(PathBuf::new(), &ret.program)
        .build(&ret.program)
        .semantic;

    let program = allocator.alloc(ret.program);
    let transform_options = TransformOptions {
        target: TransformTarget::ES5,
        react_jsx: Some(ReactJsxOptions {
            runtime: Some(ReactJsxRuntimeOption::Valid(ReactJsxRuntime::Classic)),
            ..ReactJsxOptions::default()
        }),
        ..TransformOptions::default()
    };
    Transformer::new(&allocator, source_type, semantic, transform_options).build(program).unwrap();

    let printed =
        Codegen::<false>::new(&source_text, CodegenOptions::default()).build(program).source_text;
    println!("Transformed:\n");
    println!("{printed}");
}
