Expose the number of changes (import/create/update/delete) via the wrapper about setup-opentofu HOT 5 OPEN

I'm using the wrapper in PRs to easily get the output of of the plan command and display the result in a message on the PR.

We've been using suzuki-shunsuke/tfcmt for that functionality. That's not to say this proposal is not worthwhile, because I think it could be beneficial.

Hey @dmlb2000 not sure this is related to this issue, but you can do it with terraform and open tofu as well since it's the provider (i.e. azurerm) that needs to authenticate to azure API, not open tofu itself.
I wrote a post a while ago how to set it up, it may help you. You can find it here https://maxdon.tech/posts/github-azure-oidc/

@ilmax Hey Massimiliano, thank you for your feedback and an interesting proposal. Indeed, the wrapper was implemented to reflect the functionality of the setup-terraform action, but it does not mean that we won't extend its behaviour ;)

For context, the wrapper's features are mostly used to execute tofu commands using GitOps approach, when the tofu user reads the plan before executing the apply command. Moreover, automation of consecutive execution of the commands tofu plan and tofu apply -auto-approve is not recommended.

Could you please illustrate 2-3 use cases when the functionality you proposed would be beneficial?

Hello @kislerdm and thank you for taking time to answer here.

I'm using the wrapper in PRs to easily get the output of of the plan command and display the result in a message on the PR.

I manually implemented what I suggest here to add a comment in the PR with different colours, no changes means a green comment gets added, if I have create or update resources I use yellow and for delete I use red.

I also was thinking about dynamically adding reviewers to the PR, or triggering some notification if some resources will be deleted or such.

To me using colours helped driving attention where the PR is making some infrastructure changes. Not sure if this meets the bar, I just thought it would be an interesting functionality to add

@kislerdm is there documented concerns about automating plan and apply steps? Looking at other infrastructure as code tools, they can automate the creation resources.

For my specific use case, Azure has specific integrations with GitHub to federate service principals with actions.

This is for using Bicep but I'm wondering if it will work with OpenTofu.
