Customer reported version

Customer reported platform

Steps to reproduce

1) From the desktop, add the following snippet to a Python file inside your .nuke folder (in this case, named menuCreator.py):

import os
import nuke

def build_menus():
    nuke_menu_bar = nuke.menu('Nuke')
    nuke_menu_bar.addMenu('Links')
    links = MenuCreator()
    nuke_menu_bar.addCommand('Links/Shot Page', links.openShotPage)

class MenuCreator(object):

    def __init__(self):
        """
        Configuration for MenuCreator:
        """
        self.shotsub_url = "http://www.google.com"
 
    def _open_web_page(self, url):
        import webbrowser
        webbrowser.open(url)
 
    def openShotPage(self):
        url = self.shotsub_url.format()
        self._open_web_page(url) 

2) Then add the following snippet to your menu.py

import menuCreator
menuCreator.build_menus()

3) Launch Nuke.
