No globbing or regex 41 patterns are allowed. Use the "-v" verbose flag to verify it's 42 working and see what goimports is doing. 43 44 File bugs or feature requests at: 45 46 https://golang.org/issues/new?title=x/tools/cmd/goimports:+ 47 48 Happy hacking! 49 */ 50 package main // import "golang.org/x/tools/cmd/goimports"
