How can I configure epy to use chafa to view images?

[djfergus]

From gnome I can view images with the config "auto" (uses feh) or "/usr/bin/feh" however if I configure chafa e.g:

"Setting": {
"DefaultViewer": "/usr/bin/chafa",
...

Nothing happens. Is there any way to get this to work? Is there any documentation for the image viewer config? How is the viewer program called?

Thanks.

Found a somewhat janky solution using tmux:

"DefaultViewer": "tmux new-session chafa --watch",

(then press ctrl-c to return to epy)

Start with adding it to VIEWER_PRESET_LIST in settings.py.
