When you have a bunch of relative paths to fix, just right click on the parent folder and fix all of them at once.
Alternatively, you can press open command palette F1 and search for Relative Path Refactor.
First, you will need to install Visual Studio Code. In the command palette (Ctrl-Shift-P or Cmd-Shift-P) select Install Extension and choose RelativePathRefactor.
It will keep extensions for relative paths that have them and remove when they don't.
Make sure you have committed all your work so you can revert changes made by this plugin. Additionally, If your folder has many files, it might take a while to fix all of them. Be patient!
First, I expect some bugs. I will fix them asap. Please report!
If there's many files to fix, some may stay unsaved. At the end, please save them. I'm working on fixing this.
Currently only paths that start with . are supported. Working on that as well.
If there are multiple possible choices of files, the relative path will ignore that line.
No options available yet.
