Runtools

Runtools provide additional execution modes for code cells:

• Execute a single cell
• Execute from top cell to currently selected cell
• Execute from currently selected cell to bottom cell
• Execute all cells
• Execute all cells, ignore exceptions (requires https://github.com/ipython/ipython/pull/4993)
• Execute marked codecells (cells with green gutter area are marked)
• Stop execution (duplicate to standard toolbar button)

Description

The runtools extension adds two button groups to the main toolbar:

Code execution buttons:

Codecells can be marked by clicking on the gutter of a codecell or by clicking on the markers toolbar:

A IPython notebook with marked cells looks like this:

Installation

Copy the runtools directory to a new /static/custom/runtools directory of your IPython profile and add

require(['/static/custom/runtools/runtools.js'])

to your custom.js file so it looks like this:

$([IPython.events]).on('app_initialized.NotebookApp', function(){
  //... 
  require(['/static/custom/runtools/runtools.js'])
});

Internals

A cell.metadata.run_control.marked = true property is added to a marked codecell. The "Execute marked codecells" button loops over all codecells an executes only those cells that exhibit this metadata property.
