terraform-fmt updates files, optionally skipped via flags

[tyron]

Restore terraform-fmt behaviour from v0.1.11. Fixes #48.

By default, changes are written back to source files as usual for pre-commit hooks, but can be optionally disabled by providing a --no-autofix flag to terraform-fmt.

@brikis98 , @yorinasub17 please let me know if this is OK to be reviewed, or if you'd prefer that we don't revert the default behaviour -- rather just expose the flag to switch to the old one.

Any movement on this? Seems a few folks would like old behavior

[mleuthold]

Just my 2cents:

I thought with 1.1.17 this would have been fixed by now. Because it is not, I will still continue using 0.1.11 for auto format files.

+1 on this change. Printing the diff is not as useful as auto-correcting the styling.

Is there anything what I can do to make that change happen?

[ad-m-ss]

If anyone interested that change can be easily tested eg. via:

- repo: https://github.com/gruntwork-io/pre-commit
  rev: 837cfa83f27ec2dd4a4c6860b2a6ca9392642fe0
  hooks:
    - id: terraform-fmt
    - id: terraform-validate
      exclude: terragrunt/modules

while this is not complete its better then the current fuctionality

Can we get some traction on this. The previous functionality is much nicer.

[Fez29]

Also waiting on this functionality

[Tlunch]

Would be good to see this functionality

I found this functionality in another repository: https://github.com/antonbabenko/pre-commit-terraform?tab=readme-ov-file#terraform_fmt

    - repo: https://github.com/antonbabenko/pre-commit-terraform
      rev: v1.92.2
      hooks:
          - id: terraform_fmt
