Module: nbconvert.nbconvertapp

NbConvert is a utility for conversion of .ipynb files.

Command-line interface for the NbConvert conversion utility.

2 Classes

class IPython.nbconvert.nbconvertapp.DottedOrNone(default_value=<IPython.utils.traitlets.NoDefaultSpecified object>, allow_none=None, **metadata)

Bases: IPython.utils.traitlets.DottedObjectName

A string holding a valid dotted object name in Python, such as A.b3._c Also allows for None type.

class IPython.nbconvert.nbconvertapp.NbConvertApp(**kwargs)

Bases: IPython.core.application.BaseIPythonApplication

Application used to convert from notebook file type (*.ipynb)

convert_notebooks()

Convert the notebooks in the self.notebook traitlet

convert_single_notebook(notebook_filename)

Convert a single notebook. Performs the following steps:

  1. Initialize notebook resources
  2. Export the notebook to a particular format
  3. Write the exported notebook to file
  4. (Maybe) postprocess the written file
export_single_notebook(notebook_filename, resources)

Step 2: Export the notebook

Exports the notebook to a particular format according to the specified exporter. This function returns the output and (possibly modified) resources from the exporter.

init_notebooks()

Construct the list of notebooks. If notebooks are passed on the command-line, they override notebooks specified in config files. Glob each notebook to replace notebook patterns with filenames.

init_postprocessor()

Initialize the postprocessor (which is stateless)

init_single_notebook_resources(notebook_filename)

Step 1: Initialize resources

This intializes the resources dictionary for a single notebook. This method should return the resources dictionary, and MUST include the following keys:

  • profile_dir: the location of the profile directory
  • unique_key: the notebook name
  • output_files_dir: a directory where output files (not including the notebook itself) should be saved
init_syspath()

Add the cwd to the sys.path ($PYTHONPATH)

init_writer()

Initialize the writer (which is stateless)

postprocess_single_notebook(write_results)

Step 4: Postprocess the notebook

This postprocesses the notebook after it has been written, taking as an argument the results of writing the notebook to file. This only actually does anything if a postprocessor has actually been specified.

start()

Ran after initialization completed

write_single_notebook(output, resources)

Step 3: Write the notebook to file

This writes output from the exporter to file using the specified writer. It returns the results from the writer.
