**Customizing Doom Emacs Format Module: Setting Code Formatter for Specific File Type**

Introduction

Doom Emacs is a highly customizable Emacs distribution that provides a seamless user experience. One of the key features of Doom Emacs is its format module, which allows users to configure code formatting settings for various file types. In this article, we will explore how to change the formatter used for specific file types in the Doom Emacs format module.

Understanding Doom Emacs Format Module

The Doom Emacs format module is responsible for formatting code according to the user's preferences. It provides a set of default formatting settings for various file types, including JavaScript, Python, and HTML. However, users can customize these settings to suit their needs.

Why Customize the Formatter?

There are several reasons why you might want to customize the formatter used for specific file types in Doom Emacs. For example:

Consistency: You may want to enforce a consistent coding style across your projects, regardless of the file type.
Personal preference: You may have a personal preference for a specific formatting style that is not provided by the default formatter.
Project-specific requirements: You may need to format code in a specific way for a particular project, and the default formatter does not meet those requirements.

Changing the Formatter for Specific File Type

To change the formatter used for a specific file type in Doom Emacs, you need to modify the format configuration in your Doom Emacs configuration file. Here's an example of how to do it:
