gofmt

The command line tool gofmt is a formatting tool for Go programming language code. It is used to automatically format Go source code files according to the official Go coding style guidelines. gofmt ensures that the code is consistently formatted and adheres to a specific style, which improves code readability and maintainability.

Some key features of gofmt include:

1. Simplicity: gofmt follows a simplistic philosophy of having a single, standard way to format Go code. It removes the need for manual formatting and allows developers to focus on writing code rather than worrying about the formatting.

2. Idiomatic Go Style: gofmt enforces the official Go coding style guidelines, also known as "idiomatic Go." This includes rules related to indentation, line breaks, use of braces, spacing, import organization, and more.

3. Automatic Formatting: gofmt automatically scans a Go source code file and modifies it to match the official Go style. It takes care of the indentation levels, line wrapping, spacing, and other aspects of code formatting.

4. Integration with IDEs and Editors: gofmt is widely supported by various integrated development environments (IDEs) and text editors. This allows developers to easily format their Go code with just a few keystrokes or by configuring automatic formatting on save.

Using gofmt is considered a best practice in the Go community as it helps maintain a consistent coding style across projects and makes code easier to read and understand.
