gosortstructs

sorts structs

What

A command line tool which uses AST to sort fields of a Go struct for easier readability and better diffs. This tool is meant to be used as an underlying tool for text editors (vim-plugin). The resultant Go code conforms with gofmt but is eventually opinionated.

How

• By default, this program alphabetically sorts the struct(s) in the specified file.
• If an anonymous field is part of the struct, they are separately sorted and grouped at the end of the struct.

type Hotel struct {
   *Founder
   Rating   int
   Location string
   *Organization

}

to

type Hotel struct {
	Location       string
	Rating         int
	*Founder
	*Organization
}

Advantages

• In large codebases, it makes it easier to identify all new fields that are added to a struct if they are sorted alphabetically.
• If you've intermixed fields as in the above example, your struct tags would be wrongly indented which hampers readability.
