This script attempts to identify all CSS classes mentioned in HTML but not defined in the stylesheets.

In order to use it, just run it in the DevTools console (or add it to DevTools Snippets and run it from there).

Note that this script requires browser to support `fetch` and some ES6 features (fat arrow, Promises, Array.from, Set). You can transpile it to ES5 here: https://babeljs.io/repl/ .

Known limitations:
- it won't be able to take into account some external stylesheets (if CORS isn't set up) 
- it will produce false negatives for classes that are mentioned in the comments.

This script adds on_delete to Django migrations. It works on multi-line
definitions of ForeignKey/OneToOneField which may be in your codebase if you
have black'ened the migration files.

It's not perfect, but it doesn't create syntax errors and you can run black on
the code again afterwards.

First version:

    count = q.session.execute(count_q).scalar()
    return count

q = session.query(TestModel).filter(...).order_by(...)

# Slow: SELECT COUNT(*) FROM (SELECT ... FROM TestModel WHERE ...) ...
