Hide all Input

This extension allows hiding all codecells of a notebook. This can be achieved by clicking on the button toolbar:

Typically, all codecells are shown with their corresponding output:

Clicking on the "Toggle codecell display" toolbar button hides all codecells:

Internals

The codecell hiding state is stored in the metadata IPython.notebook.metadata.hide_input. If it is set to true, all codecells will be hidden on reload.

The nbextensions.tpl template is provided in the jupyter_contrib_nbextensions.nbconvert_support templates directory (see the docs mentioned above for how to find it)

To use, add the template to your nbconvert call:

jupyter nbconvert --template=nbextensions --to=html my_notebook.ipynb

The nbextensions template will respect the nb.metadata.hide_input flag, and filter the cell's output prompt (the bit that looks like Out[27]:). The filter is only used for html output, not for PDF or LaTeX output.

If you want to keep the cell output prompt, you will have to remove the lines

{% block output_group -%}
{%- if cell.metadata.hide_output or nb.metadata.hide_input -%}
{%- else -%}
    {{ super() }}
{%- endif -%}
{% endblock output_group %}

in the nbextensions.tpl file.
