Re: [Pydev-code] Programmatically set python interpreter and createproject

[Doubleday, D. <ddo...@vo...>]

I don't know if this will help, but this is what we do to create a new
interpreter programmatically. Prior to this call, we have gotten the
list of InterpreterInfo from Pydev, added a new InterpreterInfo object
for our new interpreter to the list, and then called this method.


    private static void setInterpreters(List<IInterpreterInfo>
validInterpreters,
                                        IProgressMonitor monitor) {

        // 1. stop any running interpreters
        List<IInterpreterInfo> interpreterList =
getInstalledInterpreters();
        // Restoring the interpreters and stopping the server shell
        for (IInterpreterInfo interpreter : interpreterList) {
            AbstractShell.stopServerShell(
                interpreter, AbstractShell.COMPLETION_SHELL);
        }

        // 2. set new interpreter info
        PydevPlugin.getPythonInterpreterManager(true).setInfos(
            validInterpreters);

        // 3. configure new interpreters
        PydevPlugin.getPythonInterpreterManager(true)
            .restorePythopathForInterpreters(monitor, null);

        // 4. persist interpreter info
        PydevPlugin.getPythonInterpreterManager(true)
            .saveInterpretersInfoModulesManager();

        // 5. get persist string and set it back to manager
        String persistInfo =
PydevPlugin.getPythonInterpreterManager(true)
            .getStringToPersist(
                validInterpreters
                    .toArray(new
IInterpreterInfo[validInterpreters.size()]));
 
PydevPlugin.getPythonInterpreterManager(true).setPersistedString(
            persistInfo);

        // 6. Reloading the Interpreter page for python
        PreferenceManager pm =
PlatformUI.getWorkbench().getPreferenceManager();
        IPreferenceNode node = pm
            .find("org.python.pydev.prefs/" //$NON-NLS-1$
                +
"org.python.pydev.ui.pythonpathconf.interpreterPreferencesPagePython");
//$NON-NLS-1$
        WorkbenchPreferenceNode wpNode = (WorkbenchPreferenceNode) node;
        wpNode.setPage(null);

    }

Subject: [Pydev-code] Programmatically set python interpreter and
createproject


Hi,
I'm trying to programmatically, in a new workspace,
- set python interpreter whose details are known,
- create a pydev project, using the interpreter.

I've tried things along the lines of

         String interpreterpersistedstring = 
"Name:dwspython:EndName:Version2.6......&&&&&";
         // as previously obtained from a getPersistedString
         IInterpreterManager im =
PydevPlugin.getPythonInterpreterManager();
         im.setPersistedString(interpreterpersistedstring);

and then create the project using

         PyStructureConfigHelpers.createPydevProject(projectname,
 
projectLocationPath,
                                                     null, // IProject[]

references
                                                     monitor,
                                                     
IPythonNature.PYTHON_VERSION_2_6,
                                                     "dwspython",
                                                     null, null, null);

The immediate problem with this is that the interpreter set with 
setPersistedString is not known by createPydevProject
also confirmed by  im.hasInfoOnInterpreter("dwspython")  returning
false.
A call    im.saveInterpretersInfoModulesManager();   does not help 
either it seems.


Any help and hints on how to do this properly is greatly appreciated!

Thanks,
