nbquarto

Key Terms

• Cell: An executing module or Markdown container in a Jupyter Notebook.
• Directive: A pipe-delineated (|) comment block recognized by Quarto and nbquarto.
• Processor: A class that tailors a cell based on its directives.

Introducing nbquarto: Your Python-Powered Notebook Enhancer

Harness the might of Python with nbquarto, a dynamic interface to externally transform Jupyter Notebook cells, designed ideally for Quarto projects. This framework streamlines your documentation process by enabling rapid creation and implementation of post-processors for Jupyter Notebooks. Although Quarto-focused, nbquarto serves as a valuable asset for any Python project leveraging Jupyter Notebooks.

Choose nbquarto for a Superior Experience

Drawing inspiration from nbdev, nbquarto steers towards a more comprehensible and less abstracted interface. It focuses on modifications to Jupyter Notebooks as to fully capitalize on Quarto’s abundant features, minimizing dependencies, and enhancing code readability.

No More Learning Curve with nbquarto

Why learn a new language (Lua) to modify content already in Python? nbquarto emerges as the Pythonic alternative to Quarto Extensions. Offering flexibility and simplicity at the cost of a negligible increase in processing time, nbquarto empowers you to control the narrative.

How Does nbquarto Work?

At the heart of nbquarto is a Processor. This component modifies a cell to fine-tune code formatting or swiftly craft complex Quarto syntax combinations. Each cell object encompasses two crucial elements: directives_ (a list of cell directives) and source (modifiable cell text).

See how easy it is to add a comment to the top of a cell’s text source:

>>> from nbquarto import Processor

>>> class BasicProcessor(Processor):
...    "A basic processor that adds a comment to the top of a cell's text source."
...
...    directives = "process"
...
...    def process(self, cell):
...        if any(directive in cell.directives_ for directive in self.directives):
...            cell.source = f"# This code has been processed!\n{cell.source}"

And in a notebook cell:

# Input
>>> #| process
... print("Hello, world!")

# Output
>>> # This code has been processed!
... print("Hello, world!")

Simplified Configuration

Say goodbye to confusion with nbquarto’s configuration file. This handy feature organizes processor use, notebook paths, and processor constants for a seamless user experience.

documentation_source: tests
processors: [
    nbquarto.processors.example:BasicProcessor,
    nbquarto.processors.autodoc:AutoDocProcessor
]

processor_args:
  AutoDocProcessor: 
      repo_owner: muellerzr
      repo_name: nbquarto

Efficient Notebook Processing

Execute the nbquarto-process command to let the configured Processor(s) work their magic on your notebooks. All processed notebooks, saved as qmd files, land safely in your desired output folder:

nbquarto-process \
--config_file tests/test_artifacts/single_processor.yaml \
--notebook_file tests/test_artifacts/test_example.ipynb \
--output_folder docs/
