go list "go:generate" files

[gta]

Hello,

is there a way to list all the files that have a `//go:generate` directive with the standard tools?

I see that `go list` can show the ignored files so I am assuming it is detecting `// +build ignore` directives, but I found nothing to lit the go generate target files.

  

Thanks in advance,

Giacomo

I know that you're asking about how to do this with the standard tools, but you can do this with grep if you're on a platform that has the command available:

grep --recursive --files-with-matches "//go:generate"

or, for short:

grep -rl "//go:generate"

This command will output a list of files with "//go:generate" in them, separated by newlines. Might be a good alternative if there's no way to do this with the go command.

Thanks for the reply,

yes I know I can grep for those files, but I was hoping that go list could give me the files in the reverse dependency order like go list -deps.

I was hoping to shave some time from our generation step.

I guess bash is my friend in this.

//go:generate is not limited to dependency on Go source files, so this
is not possible in the general case.

You are right of course.

But given that `go list` is aware of other directives such as build constraints I was wondering.

Anyways for go code generation, it would be very helpful to be able to have a list of flies on which invoke go generate in the right order from `go list`.
