What version of Go are you using (go version)?

1.8.1

Problem

When I want to run a Go program that is in ./app/ directory in my dev/test cycle, I have the following options:

1. go build -o a.out ./program && ./a.out: I don't want to have binary files laying around
2. go install ./program && $GOPATH/program: it takes two steps and too long to type.
3. cd program; go run *.go: this doesn't work when I have _test.go files. (cmd/go: allow "go run" to run command in current directory #5164)

I think we should be able to point go run to a directory, as an alternative to a list of gofiles..., and run the whole directory.

It would be great if go run ./program or just go run . to execute the program in current working directory. go tool can easily detect if an argument is a go file or directory specification, then it can discover the go source files (excl. _test.go files) on the directory and then pass it as the gofiles... arg to the actual go run.

This has been previously reported at various forums:

• cmd/go: allow "go run" to run command in current directory #5164

I am opening a new issue to see if there is interest, or if the feasibility of making this change has changed in the meanwhile.
