nbpresent 0.5.0

Next generation slides from Jupyter Notebooks

# nbpresent
> remix your Jupyter Notebooks as interactive slideshows

## Installation
```shell
pip install nbpresent
python -m nbpresent.install
```

Then either run
```python
%reload_ext nbpresent
```

_every time you start the notebook_ or _enable_ the extension for every notebook launch:
```shell
python -m nbpresent.install --enable
```

## Export
Stock `nbconvert` doesn't store quite enough information, so you'll need to do something like this:
```shell
nbpresent -i notebooks/README.ipynb -o README.html
```
The resulting file can be hosted and viewed (but not edited!) on any site with fallback to Github.

If you have installed [nbbrowserpdf](https://github.com/Anaconda-Server/nbbrowserpdf), you can also export to pdf:
```shell
nbpresent -i notebooks/README.ipynb -f pdf -o README.pdf
```

You can also pass in and get back streams:
```shell
cmd_that_generates_ipynb | nbpresent -f pdf > README.pdf
```

Here's the whole doc:


```python
!nbpresent --help
```

usage: nbpresent [-h] [-i IPYNB] [-o OUTFILE] [-f {html,pdf}]

Generate a static nbpresent presentation from a Jupyter Notebook

optional arguments:
-h, --help show this help message and exit
-i IPYNB, --ipynb IPYNB
Input file (otherwise read from stdin)
-o OUTFILE, --outfile OUTFILE
Output file (otherwise write to stdout)
-f {html,pdf}, --out-format {html,pdf}
Output format


## Development
This assumes you have cloned this repository locally:
```
git clone https://github.com/Anaconda-Server/nbpresent.git
cd nbpresent
```

### Repo Architecture

The `nbpresent` nbextension is built from `./src` into `./nbpresent/static/nbresent` with:
- `less` for style
- `es6` (via `babel`) for javascript
- `browserify` for packaging

The `nbpresent` python module (server component) is stored in the `/nbpresent` folder

### Getting Started
You'll need conda installed, either from [Anaconda](https://www.continuum.io/downloads) or [miniconda](http://conda.pydata.org/miniconda.html). You can import a Python 3.5 development environment named `nbpresent` from `./environment.yml`.

```shell
conda update env
source activate nbpresent
```

We _still_ use `npm` for a lot of dependencies, so then run:
```shell
npm install
npm run build:all
```

### Ensure development asset loading
To ensure that you always get the right assets, install the nbextension with the `symlink`, `force` and `enable` options:
```shell
python -m nbpresent.install --overwrite --symlink --enable --user
```
You may also want to pass in `--prefix` instead of user.
