Thank you!

So the <URL:https://github.com/jeresig/jquery.hotkeys> and the
<URL:https://github.com/tzuryby/jquery.hotkeys> repositories have
diverged, incompatibly. I didn't know that :-/

That's good investigation, thank you for that.

I count 6 binary packages:

=====
$ apt-cache rdepends libjs-jquery-hotkeys
libjs-jquery-hotkeys
Reverse Depends:
  libghc-gitit-data
  python3-pytest-cov
  python-pytest-cov
  python3-coverage
  python-coverage
  prometheus
=====

The source packages are:

* gitit
* python-coverage
* python-pytest-cov
* prometheus

Why are we getting different sets of packages that use
‘libjs-jquery-hotkeys’?

When I use the pattern ‘[.]bind\(["']key’ for each of those source
packages with <URL:https://codesearch.debian.net/>, I get a different
set.

These queries show matches:

<URL:https://codesearch.debian.net/search?q=[.]bind\%28[%22%27]key+package%3Agitit>
<URL:https://codesearch.debian.net/search?q=[.]bind\%28[%22%27]key+package%3Apython-coverage>
<URL:https://codesearch.debian.net/search?q=[.]bind\%28[%22%27]key+package%3Aprometheus>

This does not:

<URL:https://codesearch.debian.net/search?q=[.]bind\%28[%22%27]key+package%3Apython-pytest-cov>

Does that mean ‘python-pytest-cov’ is not using the ‘jeresig’ API?

Is there a better regex pattern to use to determine what API is used?

We get differing results, so I'd like to better understand before
choosing how to resolve this.
