Sublime Text - Close all open windows

close_all_windows.py

import sublime
import sublime_plugin


class CloseAllWindowsCommand(sublime_plugin.ApplicationCommand):
    def run(self):
        for win in sublime.windows():
            win.run_command("close_window")

Default.sublime-keymap

[
    { "keys": ["ctrl+alt+shift+w"], "command": "close_all_windows" },
]

This is in response to this StackOverflow question which asks how to close all open windows at once.

First, select Tools → Developer → New Plugin… and change its contents to that of close_all_windows.py above. Hit Save and it will automagically save it to your Packages/User folder, where Packages is the folder opened when selecting Preferences → Browse Packages…:

• Linux: ~/.config/sublime-text-3/Packages
• OS X: ~/Library/Application Support/Sublime Text 3/Packages
• Windows Regular Install: C:\Users\YourUserName\AppData\Roaming\Sublime Text 3\Packages
• Windows Portable Install: InstallationFolder\Sublime Text 3\Data\Packages

Next, select Preferences → Key Bindings and add the keybinding in Default.sublime-keymap to the User keybindings on the right. I chose CtrlAltShiftW, feel free to customize it if you want. Make sure you save the file when you're done.

Now, when you're in a situation where you have a ton of open windows you want to get rid of, just hit the keybind and they'll all close, unless there are unsaved files open, in which case it'll ask if you want to save or cancel.
