Spell check Jupyter Notebooks

If you are interested in getting some spellchecking capabilities in the markdown cells of your Jupyter notebook take a look at this repo.

You can follow these instructions:

  1. Install Jupyter notebook extensions (nbextensions). This includes Spellchecker and a that is the extension we are after in this case. Type the following in a terminal, to install it using PIP.
pip install jupyter_contrib_nbextensions

However, if Anaconda is being used the recommended method is to use conda, as shown below

conda install -c conda-forge jupyter_contrib_nbextensions

When you start your Jupyter notebook you will see a new tab: The configuration interface. In the main menu of Jupyter notebook a new tab named Nbextension will appear.

2. You need to get hold of suitable dictionaries in UTF-8 encoding. I am including some en British English and Spanish (Spain and Mexico) in this repo.

Download the files and place them in the following directory

~/.local/share/jupyter/nbextensions/spellchecker/typo/dictionaries

Note that the directory above depends on your actual installation. For instance you may find that with Anaconda on a mac you will need to place the files in the following path:

/Applications/anaconda3/share/jupyter/nbextensions/spellchecker/typo/dictionaries

3. Point the extension to the correct path.

For the British English dictionaries use the following configuration:

  • Language code for typo.js: en_GB
  • Dictionary .dic file: ./typo/dictionaries/en_GB.dic
  • Dictionary .aff file: ./typo/dictionaries/en_GB.aff

For the Spanish (Spain) ones:

  • Language code for typo.js: es_ES
  • Dictionary .dic file: ./typo/dictionaries/es_ES.dic
  • Dictionary .aff file: ./typo/dictionaries/es_ES.aff

For the Spanish (Mexico) ones:

  • Language code for typo.js: es_MX
  • Dictionary .dic file: ./typo/dictionaries/es_MX.dic
  • Dictionary .aff file: ./typo/dictionaries/es_MX.aff
