Project description

💻 context_menu 💻

A Python library to create and deploy cross-platform native context menus.

example usage


  1. Install the library via pip:

    python -m pip install context_menu

  2. Create and compile the menu:

  • You can create menus in as little as 3 lines:
    from context_menu import menus
    fc = menus.FastCommand('Example Fast Command 1', type='FILES', command='echo Hello')
  • Or you can create much more complicated nested menus:
        def foo2(filenames, params):

        def foo3(filenames, params):

        if __name__ == '__main__':
            from context_menu import menus

            cm = menus.ContextMenu('Foo menu', type='FILES')
            cm2 = menus.ContextMenu('Foo Menu 2')
            cm3 = menus.ContextMenu('Foo Menu 3')

                menus.ContextCommand('Foo One', command='echo hello > example.txt'),
                menus.ContextCommand('Foo Two', python=foo2),
                menus.ContextCommand('Foo Three', python=foo3)

Detailed Usage

ContextMenu Class

The ContextMenu object holds other context objects. It expects a name, and the activation type if it is the root menu(the first menu). Only compile the root menu.

ContextMenu(name: str, type: str = None)

Menus can be added to menus, creating cascading context menus. You can use the {MENU}.add_items{ITEMS} function to add context elements together, for example:

cm = menus.ContextMenu('Foo menu', type='DIRECTORY_BACKGROUND')

You have to call {MENU}.compile() in order to create the menu.

ContextCommand Class

The ContextCommand class creates the selectable part of the menu (you can click it). It requires a name, and either a Python function or a command (but NOT both) and has various other options

ContextCommand(name: str, command: str = None, python: 'function' = None, params: str=None, command_vars: list=None)

Python functions can be passed to this method, regardless of their location. However, the function must accept only two parameters filenames, which is a list of paths*, and params, the parameters passed to the function. and if the function is in the same file as the menu, you have to surround it with if __name__ == '__main__':

Any command passed (as a string) will be directly ran from the shell.

FastCommand Class

The FastCommand class is an extension of the ContextMenu class and allows you to quickly create a single entry menu. It expects a name, type, and command/function.

FastCommand(name: str, type: str, command: str = None, python: 'function' = None, params: str = '', command_vars: list = None)
def foo1(filenames, params):

if __name__ == '__main__':
    from context_menu import menus

    fc = menus.FastCommand('Example Fast Command 1', type='FILES', python=foo1)

Admin privileges are required on windows, as it modifies the Registry. The code will automatically prompt for Admin rights if it is not sufficiently elevated.

Advanced Usage

removeMenu method

You can remove a menu easily as well. Simply call the 'menus.removeMenu()' method.

removeMenu(name: str, type: str)

For example, if I wanted to remove the menu 'Foo Menu' that activated on type 'FILES':

from context_menu import menus

menus.removeMenu('Foo Menu', 'FILES')

params Command Parameter

In both the ContextCommand class and FastCommand class you can pass in a parameter, defined by the parameter=None variable. This value MUST be a string! This means instead of passing a list or numbers, pass it as a string separated by spaces or whatever to delimitate it.

fc = menus.FastCommand('Example Fast Command 1', type='FILES', python=foo1, params='a b c d e')

For more information, see this.

Works on the FastCommand and ContextCommand class.

command_vars Command Parameter

If you decide to pass a shell command, you can access a list of special variables. For example, if I wanted to run a custom command with the file selected, I could use the following:

fc = menus.FastCommand('Weird Copy', type='FILES', command='touch ?x', command_vars=['FILENAME'])

which would create a new file with the name of whatever I selected with an 'x' on the end. The ? variable is interpreted from left to right and replaced with the selected values (see this).

All of the preset values are as follows:

Name Function
FILENAME The path to the file selected
DIR/DIRECTORY The directory the script was ran in.
PYTHONLOC The location of the python interpreter.

Works on the FastCommand and ContextCommand class.

Opening on Files

Simply pass the extension of the file you want to open onto when creating the menu.

fc = menus.FastCommand('Weird Copy', type='.txt', command='touch ?x', command_vars=['FILENAME']) # opens on .txt files

Check out the examples folder for more complicated examples.


There are different locations where a context menu can fire (if you right click on a folder you'll get different options then if you right click on a file). The type variable controls this behavior in the library, and you can reference this table to determine the type:

Name Location Action
FILES HKEY_CURRENT_USER\Software\Classes\*\shell\ Opens on a file
DIRECTORY HKEY_CURRENT_USER\Software\Classes\Directory\shell Opens on a directory
DIRECTORY_BACKGROUND HKEY_CURRENT_USER\Software\Classes\Directory\Background\shell Opens on the background of the Directory
DRIVE HKEY_CURRENT_USER\Software\Classes\Drive\shell Opens on the drives(think USBs)

Important notes

  • The code can sometimes be really weird when it comes to admin rights on Windows. The compile() method will automatically prompt for admin rights if required, but this can cause issues sometimes. Admin rights no longer required as of version 1.2.0.

  • Almost all of the errors I've encountered in testing were when the code and the functions were in the same file. You should make a separate file for the code or surround it with if __name__ == '__main__':.

Feel free to check out a file sorter I made that implements very complex usage of this library.
