ICalico is a new method of interacting with Calico. In addition, a host of new functionality is available.


  1. Install IPython
  2. Install Calico
  3. Create a profile
    • StartCalico --create-profile
  4. Start IPython with Calico profile
    • ipython notebook --profile calico

A web page should open up which will allow you to enter scripts and Calico "magic" commands.

Getting Started

For an introduction to this manner of interacting with programs, please see:



Technically, ICalico is a "IPython kernel". However, of course ICalico can operating using any of a number of languages.


ICalico magics are "meta" commands: commands for the ICalico system, separate from any Calico language.

  • One preceding percent sign indicates a "magic line command" (applies to just the line)
  • Two preceding percent signs indicates a "magic cell command" (applies to just the cell)
  • Three preceding percent sign indicates a "magic notebook command" (applies from here to rest of notebook)

Any cell can have any number of magic commands, but they must all appear first, before any code.

%connect_info       - show ICalico JSON connection information
%edit FILENAME      - edit a file in an external editor
%%file FILENAME     - create a filename with contents of cell
%%html              - treat the cell as HTML
%lang               - get information on current language
%%lang LANGUAGE     - change language for just this cell
%%%lang LANGUAGE    - change language for rest of cells
%magic              - get information on magic meta-commands
%qtconsole          - start a qtconsole
%run FILENAME       - run a file (language determined by extension)
%%time              - time how long it takes to run this cell


Widgets allow for creating interactive interfaces, when connected to an executing kernel.
