/**
 * Basic input directive.
 *
 * ```html
 * <input nbInput></input>
 * ```
 *
 * ### Installation
 *
 * Import `NbInputModule` to your feature module.
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbInputModule,
 *   ],
 * })
 * export class PageModule { }
 * ```
 * ### Usage
 *
 * Default input size is `medium`:
 * @stacked-example(Showcase, input/input-showcase.component)
 *
 * Inputs are available in multiple colors using `status` property:
 * @stacked-example(Input Colors, input/input-colors.component)
 *
 * There are three input sizes:
 *
 * @stacked-example(Input Sizes, input/input-sizes.component)
 *
 * Inputs available in different shapes, which could be combined with the other properties:
 * @stacked-example(Input Shapes, input/input-shapes.component)
 *
 * `nbInput` could be applied to the following selectors - `input`, `textarea`:
 * @stacked-example(Input Elements, input/input-types.component)
 *
 * You can add `fullWidth` attribute to make element fill container:
 * @stacked-example(Full width inputs, input/input-full-width.component)
 *
 * Or you can bind control with form controls or ngModel:
 * @stacked-example(Input form binding, input/input-form.component)
 *
 * Use `<nb-form-field>` to add custom content to the input field.
 * First import `NbFormFieldModule`. Then put the input field and custom content into
 * `<nb-form-field>` and add `nbPrefix` or `nbSuffix` directive to the custom content.
 * `nbPrefix` puts content before input and `nbSuffix` after.
 *
 * @stacked-example(Input with icon, form-field/form-field-input.component)
 * @stacked-example(Input with button, form-field/form-field-password.component)
