In the past I've done this with

golint |
   awk '/should be/{printf("gofmt -w -r %c%s -> %s%c .\n", 39, $9, $12, 39)}' |
   sh

Thanks for the suggestion. But if your program contained:

const (
  FOO_BAR_CONST = 0
  FooBarConst = 1
)

Then gofmt would make your program cease to compile. And if someone else imported your package and used p.FOO_BAR_CONST, then changing it to FooBarConst would make someone else's code cease to compile.

gofmt must always be safe to run, so we cannot do this.

Thank you for a critical example and your polite response.
This seems bad and I can figure out the risk.
