About

The IPython notebook allows extending the frontend functionality (i.e. what you do in the Browser) using extensions written in Javascript. This repository contains a collection of such extensions. The maturity of the provided extensions may vary, please create an issue if you encounter any problems.

Overview

Name	Description
[nbconvert-button][]	add a button to call 'nbconvert --to html' for current notebook
printview-button	like nbconvert-button, additionally display in new browser tab
navigation-hotkeys	add PGUP / PGDOWN / HOME / END for fast navigation in codecells
comment-uncomment	toggle comments in selected lines using Alt-C
read-only	allow codecells to be set read-only, so no editing or celle execution is possible
breakpoints	allow setting breakpoints at individual notebook cells
shift-tab	assign shift-tab to dedent
help-panel	display a static help panel besides the notebook
codefolding	fold code blocks using Alt-F or clicking on line numbers

General installation instruction

Extensions can be installed by copying the corresponding javascript extension and it's accompanying files to the static/custom directory of your IPython profile. You can find out your profile directory by starting IPython and executing

  $ ipython locate

This will give you something like ' /home/you/.ipython'

So your path to copy the extensions will be '/home/you/.ipython/profile_default/static/custom'

Finally, modify the file custom.js to load the desired extension.

IPython.hotkeys=[];
require(['/static/custom/helper-functions.js']) 

initExtensions = function(){
    require(['/static/custom/read-only.js'])
    require(['/static/custom/breakpoint.js'])
    require(['/static/custom/comment-uncomment.js'])
//    require(['/static/custom/split-combine.js'])
    require(['/static/custom/shift-tab.js'])
    require(['/static/custom/nbconvert_button.js'])
    }
 $([IPython.events]).on('app_initialized.NotebookApp',initExtensions);
