Create notebooks from python files:

  jupytext --to notebook foo.py  # creates foo.ipynb

Create html files from notebooks:

  jupyter-nbconvert --to html foo.ipynb  # creates foo.html

Create images from att files
(works with HFST command line tools from branch hfst-dev-4.0):

  cat image11.att | hfst-txt2fst --named-states=Root --states-file=image11.states > image11.hfst
  cat image11.hfst | hfst-fst2txt --state-names=image11.states --format=dot > image11.dot
  dot -Tpng image11.dot -o image11.png

Create all ipynb and html files from py files:

  for file in */src/Lecture.py; do echo $file && jupytext --to notebook $file ; done
  for file in */src/Lecture.ipynb; do echo $file && jupyter-nbconvert --to html $file ; done
  for dir in */src/; do cd $dir && pwd && mv Lecture.ipynb ../ && mv Lecture.html ../ && cd ../.. ; done

Note: '!' and '#' need sometimes be inserted as "!" and "#" in the .py file
to be interpreted correctly when producing the .ipynb file. These escaped characters
must be manually changed back to literal '!' and '#' in the .ipynb file:

  perl -pe 's/\&\#33\;/!/g; s/\&\#35\;/#/g;'

(These escaped formats have been used in files Lecture1/Lecture.py and Lecture3/Lecture.py.)
