/**
 * A decorator which can be applied to top level methods on an extension to
 * identify them as helpers. This can be used as a replacement for the
 * `createHelpers` method.
 *
 * To allow the TypeScript compiler to automatically infer types, please create
 * your methods with the following type signature.
 *
 * ```ts
 * import { CommandFunction } from '@remirror/core';
 *
 * type Signature = (...args: any[]) => CommandFunction;
 * ```
 *
 * The following is an example of how this can be used within your extension.
 *
 * ```ts
 * import { helper, Helper } from '@remirror/core';
 *
 * class MyExtension {
 *   get name() {
 *     return 'my';
 *   }
 *
 *   @helper()
 *   alwaysTrue(): Helper<boolean> {
 *     return true;
 *   }
 * }
 * ```
 *
 * The above helper can now be used within your editor instance.
 *
 * ```tsx
 * import { useRemirrorContext } from '@remirror/react';
 *
 * const MyEditorButton = () => {
 *   const { helpers } = useRemirrorContext();
 *
 *   return helpers.alwaysTrue() ? <button>My Button</button> : null
 * }

 * A decorator which can be applied to top level methods on an extension to

 *
 * If you prefer not to use decorators, then you can continue using

 * for documentation purposes.
 *
 * For automated type inference methods that use this decorator must implement
 * the following type signature.
 *
 * ```ts
 * import { CommandFunction } from '@remirror/core';
 *
 * type Signature = (...args: any[]) => CommandFunction;

 *

 *   }) => {dispatch?.(tr.insertText('my command ' + text)); return true;
 *     }
 *   }
 * }
 * ```
 *
