## Usage

This prompt is anonymous, meaning you can register this prompt with the type name you please:

```javascript
inquirer.registerPrompt('fs-selector', require('inquirer-fs-selector'));
inquirer.prompt({
  type: 'fs-selector',
  // ...
})
```

Change `fs-selector` to whatever you might prefer.

> **Note:** allowed options written inside square brackets (`[]`) are optional. Others are required.

Takes `type`, `name`, `message`, `basePath`[, `default`, [`options`](#options) ] properties.

See [inquirer.js README](https://github.com/SBoudrias/Inquirer.js/blob/master/README.md) for meaning of all except **basePath** and **default**.

Which are:
- **`basePath`** the relative path from your current working directory
- **`default`** the name of the item (*string*) where the pointer will be initially positioned (default: `'.'`)

#### Return

An object with the following shape

```typescript
{
  isDirectory: Boolean
  isFile: Boolean
  path: String // path to selected file/directory
}
```

#### Example

```javascript
const inquirer = require('inquirer')
inquirer.registerPrompt('fs', require('inquirer-fs-selector'))
// ...
inquirer.prompt([{
  type: 'directory',
  name: 'fs',
  message: 'Choose a file or directory',
  basePath: './',
  options: {
    displayHidden: true,
    displayFiles: true,
    canSelectFile: true,
    icons: {
      currentDir: '\u{1F4C2}',
      // dir: '\u{1F4C1}',
      // file: '\u{1F4C4}',
    },
    // icons: false, // Do not display icons
    shouldDisplayItem: (isDir, isFile, path) => true, // display file/directory
  }
}]).then((answers) => {
  console.log(answers.fs)
})
