How to launch an EDITOR (e. g. vim) from a python script?

You can launch an editor like Vim from a Python script using the subprocess module. Here's how you can do it:

import subprocess editor = "vim" # Replace with the path to your desired text editor if it's not in the system's PATH # The file you want to edit file_to_edit = "example.txt" # Replace with the path to your file # Launch the editor with the specified file subprocess.call([editor, file_to_edit])

In this example:

  1. We import the subprocess module.

  2. We specify the editor you want to use by setting the editor variable to the editor's executable name (e.g., "vim"). If the editor is not in the system's PATH, provide the full path to the editor's executable.

  3. We specify the file you want to edit by setting the file_to_edit variable to the path of the file you want to open or create.

  4. We use subprocess.call() to launch the editor with the specified file. The subprocess.call() function will block the script until you close the editor.

When you run this script, it will open the specified file in the editor you've chosen (e.g., Vim), allowing you to edit the file. After you close the editor, the script will continue to execute.
