Vim/Neovim plugin for editing Jupyter notebook (ipynb) files through notedown.

http://www.vim.org/scripts/script.php?script_id=5506

1. Copy the ipynb_notedown.vim script to your vim plugin directory (e.g. $HOME/.vim/plugin). Refer to :help add-plugin, :help add-global-plugin and :help runtimepath for more details about Vim plugins.
2. Restart Vim.

When you open a Jupyter Notebook (*.ipynb) file, it is automatically converted from json to markdown through the notedown utility. Upon saving the file, the content is converted back to the json notebook format.

The purpose of this plugin is to allow editing notebooks directly in vim. The conversion json → markdown → json is relatively lossless, although some of the restrictions of the notedown utility apply. In particular, notebook and cell metadata are lost, and consecutive markdown cells are merged into once cell.

The following settings in your ~/.vimrc may be used to configure the plugin:

• g:notedown_enable=1

  You may disable the automatic conversion between the notebook json format and markdown (i.e., deactivate this plugin) by setting this to 0.

• g:notedown_code_match='all'

  Value for the --match command line option of notedown. There are known problems with using the value 'strict', but 'fenced' may be a good alternative if you need code blocks in markdown.
