Extending TCC and TCC-RT with Plugins

Plugins are user-written DLL's that allow developers to create new (or replacement):

  • Internal commands
  • Internal variables
  • Variable functions
  • Keystroke monitors
  • Tab completion functions

TCC will automatically load plugins at startup, and they will override existing internal names, so you can extend and/or replace commands and variables.

Plugins can also access the Take Command IPC interface to communicate with the controlling Take Command instance. That interface allows the plugin to do things like activate tab windows, detach them, change the font, start new tabs, change the File Explorer directory, etc.

Keystroke Plugins

You can also write keystroke plugins that will be called for every keystroke entered at the command line. A keystroke plugin can perform actions when a specific key is entered, or even change the key before passing it back to the command processor. Keystroke plugins are called after key aliases, and before TCC looks for the default action for that key.

TCC Plugin SDK

Plugins can be written in any language that can create a Windows DLL. The Plugin SDK (updated for version 30) includes all the files you need to develop plugins in C / C++ or Delphi. Documentation is in the ZIP file.

The SDK is available on our web site at
