autoplan triggering in directories without .tf files

[grimm26]

The way that DetermineProjects works now is that it looks for modified files whose names contain .tf or is terragrunt.hcl. I use terragrunt.hcl, and at the top of my terraform repository is a terragrunt.hcl file and a common.tfvars file. There are no actual terraform config files, just subdirectories containing the terraform config files. So when I change the top level terragrunt.hcl file or the common.tfvars file, atlantis tries to run a plan and fails because there isn't actually any terraform config to plan.

#1075 has code to add an exception to ignore .tfline.hcl file changes and whatever else we care to add, but my problem depends on context. We need to ignore changes to terragrunt.hcl and files containing .tf if there are no .tf files in the directory. I assume that check should go about here when we get the project directories that the modified files belong to.

or probably better to check in the first place at

atlantis/server/events/vcs/github_client.go

Line 97 in 25cd66d

func (g *GithubClient) GetModifiedFiles(repo models.Repo, pull models.PullRequest) ([]string, error) {

If you have an atlantis.yaml file you can specify each directory that should be tracked. You can then not set the root directory.

Yes, but that doesn't make this not a bug.

Okay I re-read it now and I think I understand it better, you want the logic: if the file modified is terragrunt.hcl and the directory that terragrunt.hcl is in contains no .tf files then ignore?

yes

[grimm26]

it went stale because it was ignored.
