Hi, FWIW I believe printing every build constraint for every file skipped is far too verbose, even for -n or -v mode. It is not uncommon to use build constraints and when you do, you often do it for many or even all files in a package. I don't even think it would be helpful, because it would be very hard to glean the relevant information from it.
That's notably very different from a distinct flag or command, which doesn't spam in the common case and can filter the information down to a more useful subset. Why build a regexp later for something build tool knows in situ? > You don't need a regexp. You just need to grep for `// +build`. In the future (after go 1.18), you can grep for `//go:build` and get a per-file DNF form of all build constraints in a package. Again, just to be on record: I'm not denying the usefulness of tooling being able to give you more insight into if and why files are excluded from the build.
