The new --trace-plugins command-line argument makes a lot easier for people
trying to understand why a particular plugin didn't load.
It eliminates the need to set tracing variables in Leo's core--an important
advantage.
As a happy side effect, this setting simplifies the corresponding tracing
conditions in the affected core code.
Furthermore, the tracePlugins keyword argument has now been added in
various places to the leoBridge module.
Suppose example, suppose leo_bridge_test.py contains::
'''A minimal Leo bridge application'''
# This can not be run locally!
import leo.core.leoBridge as leoBridge
b = leoBridge.controller(
gui='nullGui',loadPlugins=True,
silent=False,tracePlugins=True,verbose=False)
g = b.globals()
path = g.os_path_finalize_join(g.app.loadDir,'..','doc','LeoDocs.leo')
assert g.os_path_exists(path)
c = b.openLeoFile(path)
assert c
assert c.rootPosition()
The following script will run this file::
g.cls()
import sys
import subprocess
path = r'c:\Users\edreamleo\test\leo_bridge_test.py'
assert g.os_path_exists(path)
proc = subprocess.Popen([sys.executable,path])
proc.communicate()
And the output will be::

Finally, recent code changes have eliminated duplicate console messages
when using the nullGui, as is typical when using the Leo bridge.
