goimports:tldr:caf42

This command is used to automatically format and fix import statements in a Go source file. Here's a breakdown of each part:

• goimports: It is the name of the command-line tool that is used to update import statements in Go code.

• -local ${path-to-package}: This flag specifies the package name of the project or module root directory. It is used to determine whether an import path is local (within the module) or external. The specified path should be the import path of the package which is the root of your project or module. For example, if your project is located at /Users/username/go/src/github.com/yourusername/yourproject, then the local path could be github.com/yourusername/yourproject.

• ${filename}.go: This is the name of the Go source file that you want to run the goimports command on. Replace ${filename} with the actual name of the file you want to process.

When you run this command, goimports will process the specified file and update the import statements based on the following actions:

• It will remove any import statements that are no longer needed.
• It will sort the import statements.
• It will group the imports into standard library imports, third-party package imports, and local package imports.
• It will add missing import statements for any packages that are referenced but not imported.

Overall, the purpose of this command is to help maintain consistent and properly formatted import statements in your Go code.
