Strip output from Jupyter and IPython notebooks
===============================================
.PP
Opens a notebook, strips its output, and writes the outputless version to the
original file.
.PP
Useful mainly as a git filter or pre\-commit hook for users who don't want to
track output in VCS.
.PP
This does mostly the same thing as the `Clear All Output` command in the
notebook UI.
.PP
Usage
=====
.PP
Strip output from IPython / Jupyter / Zeppelin notebook (modifies the file in\-place): ::
.IP
nbstripout <file.ipynb>
nbstripout <file.zpln>
.PP
By default, nbstripout will only modify files ending in '.ipynb' or '.zpln', to
process other files us the '\-f' flag to force the application.
.IP
nbstripout \fB\-f\fR <file.ipynb.bak>
.SS "For using Zeppelin mode while processing files with other extensions use:"
.IP
nbstripout \fB\-m\fR zeppelin \fB\-f\fR <file.ext>
.PP
Use as part of a shell pipeline: ::
.IP
cat FILE.ipynb | nbstripout > OUT.ipynb
cat FILE.zpln | nbstripout \fB\-m\fR zeppelin > OUT.zpln
.PP
Set up the git filter and attributes as described in the manual installation
instructions below: ::
.IP
nbstripout \fB\-\-install\fR
.PP
Set up the git filter using ``.gitattributes`` ::
.IP
nbstripout \fB\-\-install\fR \fB\-\-attributes\fR .gitattributes
.PP
Set up the git filter in your global ``~/.gitconfig`` ::
.IP
nbstripout \fB\-\-install\fR \fB\-\-global\fR
.PP
Set up the git filter in your system\-wide ``$(prefix)/etc/gitconfig`` (most installations will require you to ``sudo``) ::
.IP
[sudo] nbstripout \fB\-\-install\fR \fB\-\-system\fR
.PP
Remove the git filter and attributes: ::
.IP
nbstripout \fB\-\-uninstall\fR
.PP
Remove the git filter from your global ``~/.gitconfig`` and attributes ::
.IP
nbstripout \fB\-\-uninstall\fR \fB\-\-global\fR
.PP
Remove the git filter from your system\-wide ``$(prefix)/etc/gitconfig`` and attributes ::
.IP
nbstripout \fB\-\-uninstall\fR \fB\-\-system\fR
.PP
Remove the git filter and attributes from ``.gitattributes``: ::
.IP
nbstripout \fB\-\-uninstall\fR \fB\-\-attributes\fR .gitattributes
.PP
Check if ``nbstripout`` is installed in the current repository
(exits with code 0 if installed, 1 otherwise): ::
.IP
nbstripout \fB\-\-is\-installed\fR
.PP
Print status of ``nbstripout`` installation in the current repository and
configuration summary of filter and attributes if installed
(exits with code 0 if installed, 1 otherwise): ::
.IP
nbstripout \fB\-\-status\fR
.PP
Do a dry run and only list which files would have been stripped: ::
.IP
nbstripout \fB\-\-dry\-run\fR FILE.ipynb [FILE2.ipynb ...]
.PP
Print the version: ::
.IP
nbstripout \fB\-\-version\fR
.PP
Show this help page: ::
.IP
nbstripout \fB\-\-help\fR
.PP
Manual filter installation
==========================
.PP
Set up a git filter using nbstripout as follows: ::
.IP
git config filter.nbstripout.clean '/path/to/nbstripout'
git config filter.nbstripout.smudge cat
.PP
Create a file ``.gitattributes`` or ``.git/info/attributes`` with: ::
.IP
*.ipynb filter=nbstripout
.PP
Apply the filter for git diff of ``*.ipynb`` files: ::
.IP
git config diff.ipynb.textconv '/path/to/nbstripout \fB\-t\fR'
.PP
In file ``.gitattributes`` or ``.git/info/attributes`` add: ::
.IP
*.ipynb diff=ipynb
