This: use_plugin_path('xafs') from feffdat import feffpath works as expected. It adds the path to larch's xafs plugins into the search path and imports "feffdat" such that it can be used in the namespace of the plugin I am working on. This fails use_plugin_path('wx') from plotter import newplot, plot with this error message: file <stdin>, line 0 ImportError: cannot import name newplot add_plugin('f85ut') What am I not understanding? newplot (and plot) seem to be exported by wx/plotter.py the same way that feffpath is exported by xafs/feffdat.py.
