OpenSCAD Leaves Leftovers: Fix Residual Files After Uninstall

by Axel Sørensen 62 views

Hey guys! 👋 We've got a bit of a pesky bug report here concerning OpenSCAD and its cleanup act after uninstallation. It seems like OpenSCAD is leaving some digital footprints behind, and we need to tidy things up!

The Issue: OpenSCAD's Lingering Leftovers 👻

So, here’s the deal. When you install OpenSCAD using Scoop, everything goes smoothly. The post_install script does its job, creating a shortcut and a shim (a little helper file that makes running OpenSCAD from the command line a breeze). You can see this in action in the Extras bucket. This is all well and good, making OpenSCAD super accessible on your system.

The problem arises when you decide to uninstall OpenSCAD. Unlike a clean break-up, OpenSCAD doesn’t remove the shortcut and shim files it created. These files hang around like unwanted guests, cluttering your system even after the main program is gone. This isn't ideal, as it can lead to confusion and a slightly messy user experience. We want a clean uninstall, leaving no traces behind!

Why is this happening?

This happens because there's no corresponding script to remove these files during the uninstallation process. The post_install script creates them, but there’s no post_uninstall script to clean them up. It’s like building a sandcastle but forgetting to knock it down when you're done – the remnants stay put.

Proof in the Pudding: Seeing the Issue in Action 🧪

Let's get technical for a moment and show you how to reproduce this issue. Fire up your PowerShell and follow these steps:

  1. Install OpenSCAD:
    scoop install openscad
  2. Uninstall OpenSCAD:
    scoop uninstall openscad
  3. Check for the Shortcut:
    Test-Path "$([System.IO.Path]::Combine([Environment]::GetFolderPath('StartMenu'), 'Programs', 'Scoop Apps'))\openscad.lnk"
    This command checks if the shortcut still exists in your Start Menu. If it returns True, the shortcut is still there.
  4. Check for the Shim:
    Test-Path "$env:SCOOP\shims\openscad.shim"
    This checks if the shim file is still lingering in your Scoop shims directory. Again, True means it’s still around.

If you've followed these steps, you’ll likely see that the shortcut and shim files are indeed left behind. It’s a clear sign that we need a better cleanup mechanism.

Visual Evidence: A Picture is Worth a Thousand Words 🖼️

To further illustrate the issue, here’s a screenshot showing the residual files after uninstallation:

You can see that even after OpenSCAD is uninstalled, the shortcut and shim stubbornly remain.

The Solution: A Post-Uninstall Cleanup Crew 🛠️

So, how do we fix this? The solution is pretty straightforward: we need to add a post_uninstall script to the OpenSCAD manifest. This script will be responsible for removing the shortcut and shim files when OpenSCAD is uninstalled. Think of it as a cleanup crew that comes in after the main event to tidy up the place.

What the post_uninstall Script Should Do 📝

The post_uninstall script should perform the following actions:

  1. Remove the Shortcut: Delete the OpenSCAD shortcut from the Start Menu.
  2. Remove the Shim: Delete the openscad.shim file from the Scoop shims directory.

By adding these steps to the post_uninstall script, we ensure that OpenSCAD leaves no trace behind when it’s uninstalled. It’s all about keeping things clean and tidy!

How to Implement the Solution 💻

To implement this fix, we need to modify the OpenSCAD manifest file in the Extras bucket. This involves adding a post_uninstall section to the JSON manifest, specifying the commands to remove the shortcut and shim files. Here’s a rough idea of what the post_uninstall section might look like:

"post_uninstall": [
    "Remove-Item -Path \"$([System.IO.Path]::Combine([Environment]::GetFolderPath('StartMenu'), 'Programs', 'Scoop Apps'))\\openscad.lnk\" -Force",
    "Remove-Item -Path \"$env:SCOOP\\shims\\openscad.shim\" -Force"
]

This is a simplified example, and the exact commands might need to be adjusted based on the specific requirements. The key is to ensure that the script correctly identifies and removes the shortcut and shim files.

Contributing to the Solution 💪

If you're feeling adventurous and want to contribute to the solution, you can submit a pull request to the Scoop Extras repository. This involves:

  1. Forking the Extras repository: Create your own copy of the repository on GitHub.
  2. Creating a new branch: Make a new branch in your forked repository for the OpenSCAD fix.
  3. Modifying the OpenSCAD manifest: Add the post_uninstall section to the openscad.json file.
  4. Testing the changes: Ensure that the script correctly removes the shortcut and shim files during uninstallation.
  5. Submitting a pull request: Propose your changes to the main Extras repository.

Contributing to open-source projects like Scoop is a great way to give back to the community and improve the tools we all use. Plus, it’s a fantastic learning experience!
