This extension allows hiding of an individual codecell in a notebook. This can be achieved by clicking on the toolbar button:
The codecell hiding state is stored in the metadata cell.metadata.hide_input.
If it is set to true, the codecell will be hidden on reload.
See also the general docs for exporting using nbconvert at jupyter-contrib-nbextensions.readthedocs.io.
To export a notebook with hidden cell inputs using nbconvert, you need to use a
custom template.
The required template is supplied as part of
jupyter_contrib_nbextensions.nbconvert_support, or you can roll your own
using the provided ones as examples. Again, see the docs linked above for more
information.
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 cell.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.
