Summary

terraspace fmt renames source files containing ERB (<%) to *.skip before running terraform fmt, then restores them. The skip glob only matched *.{tf,skip}, so ERB .tfvars files were missed. With -recursive, terraform fmt descends into the tfvars/ subfolder and errors on them:

Error: Invalid character on tfvars/base.tfvars line 1:
1: some_var = <%= output('other-stack.x') %>

Fix: add tfvars to the glob so ERB .tfvars files are skipped like ERB .tf files. Also documents the -recursive option in the fmt help text.

Context

terraform fmt is non-recursive by default, so .tfvars in tfvars/ are only reached with -recursive, where the missing skip handling surfaced as a hard error. One-line change in lib/terraspace/cli/fmt/runner.rb:

- **/*.{tf,skip}
+ **/*.{tf,tfvars,skip}

How to Test

With an ERB .tfvars in a stack's tfvars/ subfolder, terraspace fmt -recursive errors before this change (exit 2) and succeeds after (exit 0, ERB tfvars left intact). Specs:

bundle exec rspec spec/terraspace/cli/fmt/runner_spec.rb
