why not f, err := os.Open(*file)? without the var on the above line? Is there variable shadowing I'm missing here?

@achew that would define a new f instead of assigning to the one created previously.

The error is main_test.go:118: Test 0: file misparsed, expected 'stdin', got '-'. That can be fixed by editing

grpc-gateway/protoc-gen-swagger/main_test.go

Line 25 in b15a928

checkFlags(false, "stdin", "", t, 0)

to be - instead of stdin.

So there's good news and bad news.

👍 The good news is that everyone that needs to sign a CLA (the pull request submitter and all commit authors) have done so. Everything is all good there.

😕 The bad news is that it appears that one or more commits were authored by someone other than the pull request submitter. We need to confirm that all authors are ok with their commits being contributed to this project. Please have them confirm that here in the pull request.

Note to project maintainer: This is a terminal state, meaning the cla/google commit status will not change from this State. It's up to you to confirm consent of the commit author(s) and merge this pull request when appropriate.
