Golang: Out of Sync / right-click test configurations

[promiseofcake]

Versions: IDEA Ultimate 2017.3.3 / 2018.01.02.0.1
          IDEA Ultimate 2017.3.1 / 2017.11.20.0.4

We are missing the right-click Run/Debug options in Golang projects that we have for Java/Scala.

We can execute tests form the corresponding BUILD file, but not from the context of the test file itself either as a whole unit or an individual method.

It also appears that the Workspace is frequently out-of-sync (via the light in the toolbar).

Sample .bazelproject:

directories:
  .

targets:
  //...

additional_languages:
  go

I am interesting in contributing, would we just need to port somethings over from the Java/Scala invocations?

You don't see these from right clicking?

Can you share your project? Or a minimal repro case?

[promiseofcake]

Thanks for the reply @chaoren, yeah I am missing those options. Let me see if I can create a reproducible example outside our private monorepo context.

@chaoren, here is one of our public projects that I was able to repro the issue with:
https://github.com/vsco/domino

I setup the project via:

• Import Bazel Proejct
• Use existing workspace (GOPATH to repo)
• Create project view from scratch (using above)
• Re-syncing project / allow indexing to complete

Via TestGetItemEmpty:

Via BUILD

Problem seems to be in rules_go.
ctx.rule.attr is empty for go_test targets.

Thank you @chaoren 👍 !

[chaoren]

Bad news. Those providers are not usable unless we load their definitions from the rules_go repo into our aspect, but we also run the aspect for non-go workspaces, and there's no such thing as a conditional load. We'll need to talk with the bazel people about potentially changing the providers API.

[promiseofcake]

Is the rules_go project the only one that is not following the same convention for those providers? It would seem that in that case if let's say rules_scala made a similar change we would lose functionality there as well right?

[brendandouglas]

We're in discussions with the Skylark folks now to come up with a solution for this (likely adding support for a conditional load).

The only reason our plugin currently works for java-like languages (java, scala, kotlin) is that the java providers we use are bundled with Bazel. This is something we're going to have to solve for all languages.

[promiseofcake]

It works as of the latest plugin and IDE.
