Summary: Move plugin loading, load all plugins on first request
Initial Comment:
Now plugins are loaded only in the constructor of OBConversion and forcefields
are not found if OBConversion() hasn't been run. Not all of the plugins are for
file format conversion, so it is not appropriate to load all plugins in
OBConversion::OBConversion().
In following attachment a sample program which demonstrates the issue.
It can also be demonstrated using Python:
>>> import openbabel as ob
>>> print(ob.OBForceField.FindForceField("UFF"))
None
>>>
This patch moves the plugin loading from OBConversion::OBConversion() to
OBPlugin class.
Variable "AllPluginsLoaded" keeps track if plugins have been loaded.
Function "LoadAllPlugins()" loads all plugins the same way as .OBConversion
constructor did.
These functions have to check if plugins have been loaded:
- OBPlugin::BaseFindType()
- OBPlugin::ListAsVector()
Comments are welcome.
