@dnk8n @maker2413 Hello, thank you for your feedback and thanks for testing out Terravision and helping to make this a better product. I have recently completed a major revamp to the code which uses the terraform binary to download source files and generate initial relationships, before augmenting it with source code parsing as before. This is a significant departure from the previous approach and whilst slower, ensures a more accurate output and will handle all terraform in built functions now when encountered in the source. Please do a git pull and re-test again with the latest source code. If your problem is resolved, please close the the thread in github issues and mark it as completed. If not, please give as much detail as you can about the errors and include any source files if possible so I can reproduce your issue. Once again, thanks for helping and look forward to hearing from you soon.

I plan to be able to give feedback this week. It’s on my task list. Please
understand that terravision is not right at the top. Anyone else able to
validate and report their experience?

I had a go with the new code, thanks for your patience... I understand how exciting it is to roll out a new feature and how frustrating it is waiting for feedback!

First, my project used a backend conf for terraform init, so I needed to hardcode that for this exercise - logged an issue here: https://github.com/patrickchugh/terravision/issues/85

Then when reinstalling from scratch, I needed to manually install debugpy before I could continue.

Now that I am properly installed, I could run:

(terravision-py3.10) dean@dean-ThinkPad-X250:/tmp/terravision$ terravision draw --source ~/src/dtrack --varfile ~/src/dtrack/terraform.tfvars

It did all the right things until the end:

Plan: 12 to add, 0 to change, 0 to destroy.

─────────────────────────────────────────────────────────────────────

Saved the plan to: tfplan.bin

To perform exactly these actions, run the following command to apply:
    terraform apply "tfplan.bin"

Analysing plan..

<!-- gh-comment-id:1833301927 --> @dnk8n commented on GitHub (Nov 30, 2023): I had a go with the new code, thanks for your patience... I understand how exciting it is to roll out a new feature and how frustrating it is waiting for feedback! First, my project used a backend conf for terraform init, so I needed to hardcode that for this exercise - logged an issue here: https://github.com/patrickchugh/terravision/issues/85 Then when reinstalling from scratch, I needed to manually install debugpy before I could continue. Now that I am properly installed, I could run: ``` (terravision-py3.10) dean@dean-ThinkPad-X250:/tmp/terravision$ terravision draw --source ~/src/dtrack --varfile ~/src/dtrack/terraform.tfvars ``` It did all the right things until the end: ``` Plan: 12 to add, 0 to change, 0 to destroy. ───────────────────────────────────────────────────────────────────── Saved the plan to: tfplan.bin To perform exactly these actions, run the following command to apply: terraform apply "tfplan.bin" Analysing plan..

@dnk8n Thanks for the feedback and patience. I have just made some bugfixes to this. Can you please try to run with latest code?

How long is the process expected to take. Unfortunately in South Africa we have electricity load shedding, and my laptop battery is about to die. Will try again when back online.
