<div>Good idea! I managed to load NeoJSON with this URL: <span>'github://svenvc/NeoJSON:ff1c22775182547af801cdfc286b3f33e8286475/repository'</span></div>

NeoJSON is for Pharo. Pharo migrated to Tonel, so NeoJSON uses Tonel.<br>
AFAIK no one has written Tonel support for Squeak. But even if there were <br>
Tonel support, NeoJSON probably has incompatibilities with Squeak, so <br>
you'll have to port it.<br>
If you need to process JSON files, I suggest using the Json package.<br>
If you specifically need NeoJSON, you can either use an earlier commit <br>
of NeoJSON which is still in FileTree format, or just file out the code <br>
from a Pharo image.<br>
