Adding Lines Automatically in Sublime Text 3

Question

I started to learn Python and I installed Sublime Text 3. I had a problem with encoding and I solved that problem by adding the following lines

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

Is it possible write these lines automatically at the opening of each file?

Answer 1

This can be done with a very simple plugin. Select Tools → Developer → New Plugin…, delete the boilerplate content that is there, and enter the following:

import sublime
import sublime_plugin


class AddShebangAndCodingCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        self.view.insert(edit, 0, "#!/usr/bin/env python3\n# -*- coding: utf-8 -*-\n")


class AddShebangListener(sublime_plugin.EventListener):
    def on_new(self, view):
        view.run_command("add_shebang_and_coding")

Hit Save, which will automatically put you in your Packages/User directory, and save the file as add_shebang_and_coding.py. As soon as you do that it will be loaded. Hit CtrlN (⌘N on macOS) to create a new file, and you should see the text at the top.
