How to refresh the interpreter

[vincent lapointe]

Hi,
 
I'm changing the INTERPRETER_PATH_NEW preference with the preference store of the pydev plugin. How can I send a refresh command to the pydev plugin to make sure it is updated?
 
See the sample below...
 
 
Note: sometimes, pydev automatically detected my preference change and automatically refresh the plugin, but sometimes it doesn't. Is there a particular reason?
 
Thanks
 
Vincent

Hi Vincent.

The actual way to create an interpreter would be something as:

IInterpreterManager iMan = PydevPlugin.getPythonInterpreterManager(true);
IInterpreterInfo interpreterInfo = ... (create your interpreter info here)
iMan.addInterpreterInfo(interpreterInfo);
iMan.restorePythopathForAllInterpreters(monitor);
iMan.setPersistedString(iMan.getStringToPersist(new
IInterpreterInfo[]{interpreterInfo}));
iMan.saveInterpretersInfoModulesManager();

Cheers,

Fabio

Hi Fabio=2C
=20
I made the modifications based on what you suggested.
=20
However=2C when I apply the changes=2C all opened projects with python natu=
re throw the following exception. (Note that pydev console also generated a=
 similar exception)
=20
Invalid interpreter: Default configured for project: Project1.
org.python.pydev.core.ProjectMisconfiguredException: Invalid interpreter: D=
efault configured for project: Project1.
 at org.python.pydev.plugin.nature.PythonNature.getProjectInterpreter(Pytho=
nNature.java:1051)
 at org.python.pydev.plugin.nature.PythonNature.getConfigErrorsAndInfo(Pyth=
onNature.java:1100)
 at org.python.pydev.navigator.ProjectInfoForPackageExplorer.getConfigError=
sAndInfo(ProjectInfoForPackageExplorer.java:79)
 at org.python.pydev.navigator.ProjectInfoForPackageExplorer.recreateInfo(P=

 at org.python.pydev.navigator.PythonBaseModelProvider$Updater.run(PythonBa=
seModelProvider.java:193)
 at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

Then=2C if I close my rcp application and reopen it=2C the projects with py=
thon nature and the pydev console work correctly=20
=20
Moreover=2C I checked the configuration of the interpreter in the preferenc=
e page and all settings are exactly the same as when configured automatical=
ly. Note that I set an empty dll list in the InterpreterInfo.
=20
So=2C is it normal that I should close my rcp application before the new in=
terpreter works correctly?
=20
=20
Thank again
