# Visitor utilities for AssemblyScript Compiler transformers

## Example

### List Fields

The transformer:

```ts

import {

  ClassDeclaration,

  FieldDeclaration,

  MethodDeclaration,

} from "../../as";

import { ClassDecorator, registerDecorator } from "../decorator";

import { getName } from "../utils";

class ListMembers extends ClassDecorator {

  visitFieldDeclaration(node: FieldDeclaration): void {

    if (!node.name) console.log(getName(node) + "\n");

    const name = getName(node);

    const _type = getName(node.type!);

    this.stdout.write(name + ": " + _type + "\n");

  }

  visitMethodDeclaration(node: MethodDeclaration): void {

    const name = getName(node);

    if (name == "constructor") {

      return;

    }

    const sig = getName(node.signature);

    this.stdout.write(name + ": " + sig + "\n");

  }

  visitClassDeclaration(node: ClassDeclaration): void {

    this.visit(node.members);

  }

  get name(): string {

    return "list";

  }

}

export = registerDecorator(new ListMembers());

```

assembly/foo.ts:

```ts

@list

class Foo {

  a: u8;

  b: bool;

  i: i32;

}

```

And then compile with `--transform` flag:

```

asc assembly/foo.ts --transform ./dist/examples/list --noEmit

```

Which prints the following to the console:

```

a: u8

b: bool

i: i32

```
