## Overview

The Text Block outputs a string of text and can interpolate values using `{{tags}}` within the text. The inputs are dynamically generated based on the interpolation tags used in the text.

## Inputs

<ParamField path="(Dynamic)" type="string">
  The inputs are dynamically generated based on the interpolation tags used in the text. For example, if the text contains `{{name}}`, an input named `name` will be created. All inputs are optional and accept string values. If an input is not connected, its tag will be replaced with an empty string.
</ParamField>

## Outputs

<ResponseField name="output" type="string">
  The output text after interpolating all input values into their corresponding tags.
</ResponseField>

## Editor Settings

<ParamField path="text" type="code" language="prompt-interpolation-markdown" default="{{input}}">
  The text to output. You can use interpolation tags in the format `{{tag}}` to insert input values. The text supports markdown formatting and will be displayed with syntax highlighting in the editor.
</ParamField>

<ParamField path="width" type="number" default={250}>
  The width of the block in pixels.
