Application Launchers

Kupfer – smart, quick launcher

Kupfer is software designed to change, speed up and make everything about files and programs more fun on your computer. Kupfer is heavily inspired by Quicksilver, utility software which is essentially a graphical shell for the OS X operating system aimed at improving user efficiency.

This software can search and browse your files, launch desired applications and object you need in a quicker way. Kupfer is written in Python and has a flexible architecture based on plugins to extend its features.

Kupfer’s architecture is built around objects that can be acted on by actions.

Kupfer is a Python program that allows loading extension modules at runtime. A plugin is equivalent to one Python module implemented as one .py file or as a Python package.

Features include:

  • Simple but capable launcher.
  • Handles web addresses and dictionary lookups.
  • Large range of plugins. Each plugin provides additional functionality, for example integration with an external application.
  • A kupfer plugin is a python module with special module attributes.
  • Implements the famous “comma trick”: Press , (comma) in the first or third pane to make a stack of objects to perform actions on. This allows actions on many objects and even many-to-many actions.
  • Save command-lines by using the action Add to Favorites
  • Always listens to global shortcuts, even if it is not currently in the foreground.
