format

type Options struct {
	// LangVersion corresponds to the Go language version a piece of code is
	// written in. The version is used to decide whether to apply formatting
	// rules which require new language features. When inside a Go module,
	// LangVersion should be:
	//
	//     go mod edit -json | jq -r '.Go'
	//
	// LangVersion is treated as a semantic version, which may start with a "v"
	// prefix. Like Go versions, it may also be incomplete; "1.14" is equivalent
	// to "1.14.0". When empty, it is equivalent to "v1", to not use language
	// features which could break programs.
	LangVersion string

	// ModulePath corresponds to the Go module path which contains the source
	// code being formatted. When inside a Go module, ModulePath should be:
	//
	//     go mod edit -json | jq -r '.Module.Path'
	//
	// ModulePath is used for formatting decisions like what import paths are
	// considered to be not part of the standard library. When empty, the source
	// is formatted as if it weren't inside a module.
	ModulePath string

	// ExtraRules enables extra formatting rules, such as grouping function
	// parameters with repeated types together.
	ExtraRules bool

	LocalPrefix string
