ST3: Paste the current file's Relative Path From Project (Encoded). Requires https://github.com/titoBouzout/SideBarEnhancements be installed

ST3-paste-path.py

import sublime, sublime_plugin

'''
	Paste the current file's Relative Path From Project (Encoded).
	Requires https://github.com/titoBouzout/SideBarEnhancements to be installed

	First save this file as:
	~/Library/Application Support/Sublime Text 3/Packages/User/paste-path.py
	
	More details about writing plugins: http://docs.sublimetext.info/en/latest/reference/plugins.html
	
	To trigger the command with 'Command Option Shift p',
	add the following to your Sublime Text > Preferences > Keybindings - User

	[
	    { "keys": ["super+option+shift+p"], "command": "paste_path"}
	]
	
'''

class PastePathCommand(sublime_plugin.WindowCommand):
    def run(self):
        self.window.run_command("side_bar_copy_path_relative_from_project_encoded", {"paths": []})
        self.window.run_command("paste")

I really want this but when I copy the command you provided into my Keybindings - User file, it doesn't work. What is up with the code import sublime, sublime plugin before and the class getting called at the end?

And I do have SidebarEnhancements intalled. (just to clarify)

Sorry, I left out some salient details!

You need to save this file as something like:

~/Library/Application Support/Sublime Text 3/Packages/User/paste-path.py
