### Complimentary tools



If you're interested in complimentary tools

that help improve the terminal experience for notebooks,

there are many amazing projects out there.



- **[bat](https://github.com/sharkdp/bat)**

  is not a tool for notebooks specifically.

  But similar to nbpreview,

  it provides a rich output for many types of files on the terminal,

  and is the primary inspiration for nbpreview.

- **[euporie]**

  is a really exciting project

  that allows you to edit and run Jupyter notebooks on the terminal.

- **[nbclient]**

  is a library for executing notebooks from the command line.

- **[nbpreview]**

  is another project that coincidentally shares a name with this one.

  It allows for Jupyter notebooks to be rendered

  without running a notebook server.

- **[nbqa]**

  allows the use of linters and formatters on notebooks.

  It's also used by this project.

- **[jpterm]**

  is and up-and-coming successor to [nbterm]

  which will be accompanied by a web client.

  Looking forward to seeing this develop.

- **[nbtermix]**

  is an actively-developed fork of [nbterm].

- **[nbterm]**

  lets you edit and execute Jupyter Notebooks on the terminal.

- **[papermill]**

  allows the parameterization and execution of Jupyter Notebooks.

## Credits



nbpreview relies on a lot of fantastic projects.

Check out the [dependencies] for a complete list of libraries that are leveraged.



Besides the direct dependencies,

there are some other projects that directly enabled the development of nbpreview.



- **[bat]**

  is not explicitly used in this project,

  but served as the primary inspiration.

  This projects strives to be [bat]—but

  for notebooks.

  Many of nbpreview's features and command-line options are directly adopted from [bat].

- **[Hypermodern Python Cookiecutter]**

  is the template this project was generated on.

  It is a fantastic project that integrates [Poetry],

  [Nox],

  and [pre-commit].

  It's responsible for most of this project's CI.

- **[justcharts]**

  is directly used by this project

  to generate the Vega and Vega-Lite charts.
