SYNOPSIS
goimports [flags] [path ...]
DESCRIPTION
goimports updates Go import lines by adding missing imports and removing unreferenced ones. It also formats code in the same style as gofmt, making it a drop-in replacement.
Imports are grouped with standard library first, then third-party packages, and sorted alphabetically within each group. The -local flag allows separating project-specific imports into their own group.
