Customizable cell headers for Jupyter

Headers is a Jupyter Lab plugin which allows users to create notebook cells with custom headers. Three built in buttons are provided: ! and % for IPython commands and %%spark. Custom buttons with new headers can be added. All built in headers have the keyboard shortcuts CMD + SHIFT followed by !, F5, and @ respectively. Commands are registered of the format "@jaredstef/headers:createCustomCell${index}" if the user wishes to map to custom buttons as well.

This package can be found on npm titled "@jaredstef/headers". 

## Requirements

- JupyterLab >= 4.0.0

## Install

To install the extension, execute:

```bash
pip install jaredstef_headers
```

## Uninstall

To remove the extension, execute:

```bash
pip uninstall jaredstef_headers
```

## Contributing

### Development install

Note: You will need NodeJS to build the extension package.

The `jlpm` command is JupyterLab's pinned version of
[yarn](https://yarnpkg.com/) that is installed with JupyterLab. You may use
`yarn` or `npm` in lieu of `jlpm` below.

```bash
# Clone the repo to your local environment
# Change directory to the jaredstef_headers directory
# Install package in development mode
pip install -e "."
# Link your development version of the extension with JupyterLab
jupyter labextension develop . --overwrite
# Rebuild extension Typescript source after making changes
jlpm build
```

You can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension's source and automatically rebuild the extension.

```bash
# Watch the source directory in one terminal, automatically rebuilding when needed
jlpm watch
# Run JupyterLab in another terminal
jupyter lab
```

With the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).

By default, the `jlpm build` command generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command:

```bash
jupyter lab build --minimize=False
```

### Development uninstall

```bash
pip uninstall jaredstef_headers
```

In development mode, you will also need to remove the symlink created by `jupyter labextension develop`
command. To find its location, you can run `jupyter labextension list` to figure out where the `labextensions`
folder is located. Then you can remove the symlink named `@jaredstef/headers` within that folder.

### Packaging the extension

See [RELEASE](RELEASE.md)
