Description of issue

I am currently using
system "go", "build", *std_go_args(ldflags:), "./cmd/main.go" because when using system "go", "build", "-o hack/switch/switcher", *std_go_args(ldflags:), "./cmd/main.go" it never renders the binary in hack/switch/switcher. I was trying to use this output in order to do the bin.install and avoid versioned switcher@0.9.1 binaries being built.

std_go_args has an optional output argument you can pass: std_go_args(output: bin/"switcher")

[cdenneen]

Is there a way to write this so it would do the linking properly?
For example if I'm using the latest formula it would be bin/"switcher"... if I'm using SwitcherAT091 then it would be bin/"switcher@0.9.1", if I'm using SwitcherAT072 it would be bin/"switcher@0.7.2" for example? I think the ability to run different versions by calling different binaries is useful possibly but would need a way for things like generate_completions_from_executable(bin/"switcher", "completion", base_name: "switcher") to work when you are installing a version of a formula.
Or maybe when you install a version of a formula it creates a link from the current version binary that gets added like switcher@0.9.1 to switcher with link... so it would update the brew unlink/link and then the generate_completions_from_executable would update completions based on the current version installed.
I could then unlink/link between versions but if I'm installing a new version most likely I'm going to want to create the link to that new version installed.

    ENV.prepend_path "PATH", Formula["coreutils"].opt_libexec/"gnubin" # needs GNU date
    system "go", "build", *std_go_args(ldflags:), "./cmd/main.go"
    bin.install "switcher"

    generate_completions_from_executable(bin/"switcher", "completion", base_name: "switcher")
  end

I've also tried:

    system "go", "build", *std_go_args(ldflags:, output: bin/"switcher"), "./cmd/main.go"

All result in:

Error: An exception occurred within a child process:
  Errno::ENOENT: No such file or directory - switcher

[carlocab]

That comes from bin.install "switcher". Get rid of it; you don't need it.
