pertain to any part of the Derivative Works, in at least one
111+
of the following places: within a NOTICE text file distributed
112+
as part of the Derivative Works; within the Source form or
113+
documentation, if provided along with the Derivative Works; or,

any Contribution intentionally submitted for inclusion in the Work
132+
by You to the Licensor shall be under the terms and conditions of
133+
this License, without any additional terms or conditions.
134+
Notwithstanding the above, nothing herein shall supersede or modify

137+
138+
6. Trademarks. This License does not grant permission to use the trade
139+

144+
agreed to in writing, Licensor provides the Work (and each
145+
Contributor provides its Contributions) on an "AS IS" BASIS,
146+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

151+
risks associated with Your exercise of permissions under this License.
152+
153+
8. Limitation of Liability. In no event and under no legal theory,
154+
whether in tort (including negligence), contract, or otherwise,
155+
unless required by applicable law (such as deliberate and grossly
156+
negligent acts) or agreed to in writing, shall any Contributor be
157+
liable to You for damages, including any direct, indirect, special,
158+
incidental, or consequential damages of any character arising as a
159+
result of this License or out of the use or inability to use the
160+
Work (including but not limited to damages for loss of goodwill,
161+
work stoppage, computer failure or malfunction, or any and all
162+
other commercial damages or losses), even if such Contributor
163+
has been advised of the possibility of such damages.
164+
165+
9. Accepting Warranty or Additional Liability. While redistributing
166+
the Work or Derivative Works thereof, You may choose to offer,
167+
and charge a fee for, acceptance of support, warranty, indemnity,
168+
or other liability obligations and/or rights consistent with this
169+
License. However, in accepting such obligations, You may act only
170+
on Your own behalf and on Your sole responsibility, not on behalf
171+
of any other Contributor, and only if You agree to indemnify,
172+
defend, and hold each Contributor harmless for any liability
173+
incurred by, or claims asserted against, such Contributor by reason

# Nodebook
2+
3+
[![CircleCI](https://circleci.com/gh/stitchfix/nodebook.svg?style=shield)](https://circleci.com/gh/stitchfix/nodebook)
4+
5+
Nodebook is a plugin for Jupyter Notebook designed to enforce an ordered flow of cell execution. Conceptually, Nodebook notebooks operate like a script where each cell depends on the cells above it. This prevents messy and difficult to maintain out-of-order execution which frequently occurs in vanilla Jupyter notebooks where each cell modifies the global state. For more information, see [this post](http://multithreaded.stitchfix.com/blog/2017/07/26/nodebook/).
6+
7+
8+
## Installation
9+
10+
Nodebook is available on pypi and can be installed with pip:
11+
```
12+
pip install nodebook
13+
```
14+
15+
## Usage
16+
17+
To use Nodebook, add the following lines to a cell in your Jupyter notebook:
18+
```
19+
#pragma nodebook off
20+
%load_ext nodebookext
21+
%nodebook {mode} {name}
22+
```
23+
Where `{mode}` is one of `memory` or `disk`, and `{name}` is a unique identifier for your notebook.
24+
25+
Mode determines whether variables are stored in memory or on disk.
26+
27+
For additional example usage, see [nodebook_demo.ipynb](./nodebook_demo.ipynb). Also see below for a quick demo showing the basic difference in behavior between Nodebook and standard Jupyter:
28+

30+
31+
## FAQ
32+
33+
#### Q: Why am I seeing "ERROR:root:Cell magic `%%execute_cell` not found."?
34+
35+
Nodebook loads a javascript plugin to modify Jupyter's behavior. If you encounter this error, it means that the javascript plugin is loaded but the ipython plugin is not. This can happen when the javascript is already loaded but you have restarted the kernel and haven't run `%nodebook {mode} {name}`. The solution is either to run the `%nodebook` magic (if you want to run nodebook), or delete the cell with the `%nodebook` magic and refresh your browser to unload the javascript (if you want to turn nodebook off).
36+
37+
#### Q: What are the tradeoffs between memory and disk mode?
38+
39+
Nodebook serializes all cell outputs to maintain consistent state between cells. In `memory` mode, objects are serialized to an in-memory dictionary, in `disk` mode objects are serialized to a directory within your notebook's working directory. Speed can be a factor when choosing between them, but on a modern SSD, serialization time generally dominates and `memory` and `disk` mode have similar performance. The main consideration is that `disk` mode has the advantage of persisting your environment when the python kernel is restarted, but the disadvantage of leaving behind a directory on your local filesystem that you may want to manually clean up later (this can add up especially if you are working with large objects in your notebook).
40+
41+
#### Q: What are the limitations of Nodebook?
42+
43+
While Nodebook supports most Python operations, it has a few limitations related to the use of serialization. First, not all objects are currently serializable, most noteably generators. Second, serialization adds some extra time. This is imperceptible for small objects, but is noticable for objects larger than a few hundred MB. Instead of working directly with very large objects in Nodebook, I recommend using it to prototype your analysis on a subset of data.
