I wonder why your terminal is not in color |
Oh, I see now I didn't realize we were not using cobra's built-in mechanism. Can you check why we are not using that because that means we have a very different implementation for this one off command! I like what you're doing more than what we had. However, it looks nothing like |

We have solved the wrapping issues in Cobra, so if we can get the menu back in there, that would be ideal. |

📝 WalkthroughWalkthroughThe pull request introduces enhancements to the Atmos CLI's Terraform command handling and help system. It focuses on improving command execution, error handling, and help output for Terraform-related commands. Key modifications include restructuring the Terraform command framework, adding dynamic help template generation, and refining the help display logic across multiple files in the project. Changes

Defining all Terraform commands in one place is convenient. For long-term maintenance, you could consider auto-generating or grouping commands logically to reduce file size.

: Consider adding error checks when building templates.While minimal, there's a risk that unexpected sections or invalid data could disrupt template building. For instance, poorly formatted strings might cause runtime issues. You could log or safely handle such anomalies.

: Potential for repeated string logic.
getSection
switches on the same enumeration in multiple places, each returning fairly similar strings. If these usage sections expand, you might consider extracting repeated blocks into helper functions or otherwise modularizing. This can streamline changes and testing, while still keeping logic local.
