A collections of utilities to manipulate IPython/Jupyter Notebooks via a python script.

## Usage/Examples
### Basic usage
A simple example of using nbmanips:

```python
from nbmanips import Notebook

# Read ipynb file
nb = Notebook.read_ipynb("my_notebook.ipynb")

# delete empty cells
nb.select("empty").delete()

# save ipynb file
nb.to_ipynb("new_notebook.ipynb")
```

Examples of operations you can perform on a Notebook:

- `replace`: Replace matching text in the selected cells
- `tag`: Add metadata to the selected cells
- `erase`: Erase the content of the selected cells
- `delete`: Delete the selected cells
- `keep`: Kepp the selected cells

### Selectors
To select cells on which to apply the previous operations, you can use:

- The cell number

```python
nb[0].show()

# OR
nb.select(0).show()
```
- A slice object

```python
nb[1:6:2].show()

# OR 
selected_cells = slice(1, 6, 2)

nb.select(selected_cells).show()
```
- A predefined selector. Available predefined selectors are the following:

    - `code_cells` / `markdown_cells` / `raw_cells`: Selects cells with the given type
    - `contains`: Selects Cells containing a certain text.
    - `is_empty` / `empty`: Selects empty cells
    - `has_output`: Checks if the cell has any output
    - `has_output_type`: Select cells that have a given output_type
    - `has_slide_type`: Select cells that have a given slide type
    - `is_new_slide`: Selects cells where a new slide/subslide starts
    - `has_byte_size`: Selects cells with byte size within a given range of values.

```python
# Show Markdown Cells
nb.select('markdown_cells').show()

# Show Cells containing the equal sign
nb.select('contains', '=').show()
```



- A function that takes a Cell object and returns True if the cell should be selected
```python
# Show Cells with length > 10
nb.select(lambda cell: len(cell.source) > 10).show()
```
- A list of Selectors
```python
# Show Empty Markdown Cells
nb.select(['markdown_cells', 'is_empty']).show()

# Show Markdown or Code Cells
nb.select(['markdown_cells', 'code_cells'], type='or').show()
```
 
### Export Formats
You can export the notebooks to these formats:

- to_ipynb
- to_dbc
- to_html
- to_slides (using reveal.js)
- to_md (to markdown)
- to_py (to python)
- to_text (textual representation of the notebook)

### Slide manipulations
You can manipulate the slides by tagging which cells to keep and which to skip. 
The following actions are available:

- set_slide 
- set_subslide
- set_skip
- set_fragment
- set_notes

A neat trick is to use `auto_slide` method to automatically create slides out of your notebook:
```python
from nbmanips import Notebook

# Read ipynb file
nb = Notebook.read_ipynb("my_notebook.ipynb")

# Automatically create slides
nb.auto_slide()

# Export to Reveal.js slides (HTML)
nb.to_slides("new_slides.slides.html", theme='beige')
```

## CLI
### Show a notebook
To get a readable representation of the notebook 
```bash
nb show my_notebook.ipynb
```

To show a subset of the notebook cells, you can perform a select operation:
```bash
nb select 0:3 | nb show my_notebook.ipynb

# Or if you're using negative indexes ( to show the last 3 cells )
nb select [-3:] | nb show my_notebook.ipynb
```
### Basic usage
A simple example of using nbmanips via the cli:

```bash
# delete empty cells
nb select empty | nb delete my_notebook.ipynb --output new_notebook.ipynb

# Or equivalently:
nbmanips select empty | nbmanips delete my_notebook.ipynb --output new_notebook.ipynb
```

### Export Formats
You can convert a notebook to the following formats:

- html: `nb convert html my_notebook.ipynb --output my_notebook.html`
- slides (using reveal.js): `nb convert slides my_notebook.ipynb --output my_notebook.slides.html`
- md (to markdown): `nb convert md my_notebook.ipynb --output my_notebook.md`
- py (to python): `nb convert py my_notebook.ipynb --output my_notebook.py`

### Slide manipulations
```bash
# Automatically set slides
nb auto-slide -f my_notebook.ipynb

# Generate a my_notebook.slides.html file
nb convert slides my_notebook.ipynb
```

Or if you do not wish to modify your original notebook:
```bash
# Automatically set slides
nb auto-slide my_notebook.ipynb -o my_temp_notebook.ipynb

# Generate a my_notebook.slides.html file
nb convert slides my_temp_notebook.ipynb -o my_notebook.slides.html
```

If you need more details you can check the --help option:
```
nbmanips --help
```
