package go/ast
SortImports sorts runs of consecutive import lines in import blocks in f. It also removes duplicate imports when it is possible to do so without data loss.
Golang go/ast.SortImports() usage example
var pkg string
...
buf := new(bytes.Buffer)
fset := token.NewFileSet()
astFile, err := parser.ParseFile(fset, pkg+".go", buf, parser.ParseComments)
if err != nil {
return errors.New("Error parsing generated code: " + err.Error())
}
// Sort the import lines in the AST in the same way that gofmt does.
ast.SortImports(fset, astFile)
