nbformat - Jupyter Notebook Format in Rust

This crate provides functionality to parse and work with Jupyter Notebook files in Rust.

Usage

Add this to your Cargo.toml:

[dependencies]
nbformat = "0.1.0"

Here's a basic example of how to use parse_notebook:

use nbformat::{parse_notebook, Notebook};
use std::fs;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Read the notebook file
    let notebook_json = fs::read_to_string("Untitled1337.ipynb")?;

    // Parse the notebook
    let notebook = parse_notebook(&notebook_json)?;

    // Work with the parsed notebook
    match notebook {
        Notebook::V4(nb) => {
            println!("Notebook version: {}.{}", nb.nbformat, nb.nbformat_minor);
            println!("Number of cells: {}", nb.cells.len());
            // Access other notebook properties...
        }
        Notebook::Legacy(nb) => {
            println!("Legacy notebook version: {}.{}", nb.nbformat, nb.nbformat_minor);
            println!("Number of cells: {}", nb.cells.len());
            // Access other notebook properties...
        }
    }

    Ok(())
}

At present, this crate supports v4.5 notebooks via Notebook::V4 and v4.1-v4.4 via Notebook::Legacy. v4.5 have some more hard constraints on CellIDs being required, only allowing certain characters, and not having duplicates. Converting from a v4.1-v4.4 notebook to a v4.5 notebook requires modifying the notebook to include Cell IDs.

ROADMAP

• Serialize and Deserialize v4.1-v4.5 notebooks into rust structures
• Test operations on a suite of notebooks from Python nbformat
• Add support for upconverting v3 notebooks to v4
• Add support for upconverting v4.1-v4.4 notebooks to v4.5
• Break out types to be shared between runtimelib's Media setup and the notebook crate
