Dogelog Player is a Prolog system mostly written
in Prolog itself. It is available for the JavaScript,
Python and Java platform. In the browser environment
it offers Notebooks that run without server roundtrip.

Compared to for example SWISH or Tinker from SWI-Prolog,
the syntax coloring is in its early stage. Notebook
cells were only colored during instrumentation. Things
have a little improved with delayed re-coloring now.

To implement recoloring of a Notebook cell, we found
it useful to resort to the debouncing event handling
pattern. It can be easily realized by storing a timer
in a DOM element (sic!). Although recoloring requires

coloring potentially invalid and incomplete tokens,
since we use a full cell recoloring, not much goes wrong.
