Filtering out Nuke’s distributed plugins is pretty simple:
import os
nukeDir = os.path.dirname(nuke.env['ExecutablePath'])
externalPlugins = [p for p in nuke.plugins() if not p.startswith(nukeDir)]
# Trim paths and/or filter extensions as needed
To find all of the external gizmos being used in your script is also simple
(given `nukeDir` from above):
# This is basic. In reality, you want to recurse into Groups
externalGizmos = [n for n in nuke.allNodes() if isinstance(n, nuke.Gizmo) and
not n.filename().startswith(nukeDir)]
Finding external plugins that are actively being used in your script (as
opposed to just loaded by Nuke) is trickier, especially if you need to account
for custom Reader/Writer classes, but you can get close pretty easily (again,
given `nukeDir`):
# Non-gizmo plugins only
externalPlugins = [p for p in nuke.plugins(0, '*.ofx', '*.%s' %
nuke.PLUGIN_EXT) if not p.startswith(nukeDir)]
It’s obviously easy to combine this with the gizmo query to get a more complete
cross-section. To filter it even further, you could try to take the results of
this call and intersect the plugin class basenames with the classes of all
nodes in your script (using special cases for OFX plugins), and then add some
more specialized crawling to track down any nodes that might be actively using
Reader/Writer plugins.
Hope this helps.

Subject: Re: [Nuke-python] Finding plugins
Here is a fragment of a code I used a while ago. It was only checking gizmos,
and was reading the info inside gizmo files that you may not need, but it might
give you an idea to adapt to your problem:
import re
def gizmoCheck():
gizmos = nuke.plugins(0, '*.gizmo')
for gizmoPath in gizmos:
gizmoLoaded = False
gizmoFile = open(gizmoPath, 'r')
gizmoTxt = ''.join(gizmoFile)
gizmoFile.close()
gizmoName = re.split('[\\\/]', gizmoPath)[-1]
gizmoName = re.sub('\.gizmo', '', gizmoName)
print 'Checking '+gizmoName
for node in nuke.allNodes():
if node.Class() == gizmoName:
gizmoLoaded = True
.....
There might be a much better way to do this, I'm still just messing with code
until I get my stuff to work.

Anyone have a good trick for getting a list of all non-Nuke standard plugins
used in a comp? Having trouble getting nuke.plugins to work without weird
errors.
Thanks!
