FR: Gazelle should import direct dependencies directly without requiring buildozer

[vicentsegui]

What version of gazelle are you using?

0.35.0

What version of rules_go are you using?

0.46.0

What version of Bazel are you using?

7.0.2

Does this issue reproduce with the latest releases of all the above?

Yes

What operating system and processor architecture are you using?

Macos

What did you do?

When using bzlmod support and go_deps being read from go.mod users still need to add manually direct dependencies to the use_repo rule. When running gazelle it will warn us when those are out of sync and give us a buildozer command to update it.

What did you expect to see?

Gazelle should be able to add this without users having to run the buildozer command. Alternatively rules_go should be able to add the direct dependencies as determined by go.mod without user intervention.

What did you see instead?

I have to run 3 commands to get everything to work:

go get $random_module # get the go module
bazel run //:gazelle  # adds dependency in BUILD file
buildozer 'use_repo_add @gazelle//:extensions.bzl $random_module' //MODULE.bazel:all  # adds the repo

With my proposal we could limit it to 2:

go get $random_module # get the go module
bazel run //:gazelle # adds dependency in BUILD file and repo in MODULE.bazel

I minor improvement comes with bazel 7.1's bazel mod tidy command.

But yes, ideally the user shouldn't have to do anything manually besides running gazelle

We'll integrate bazel mod tidy into @rules_go//go. You then only need to run bazel run @rules_go//go get ... to add a dependency (plus Gazelle). The @rules_go//go binary also does this when invoked directly, so you can wire this up with your IDE or shell aliases.

Quick question would this also work with bazel run @rules_go//go mod tidy? I tend to use that command instead of go get most of the time.

Yes, we'll watch for any changes to your go.mod instead of checking which command you ran.
