How to query current viewport renderer in maya

Anyone have a good solution for querying the current maya viewport renderer (Viewport 2.0, Default Viewport, High Quality Viewport) in python?

Iterate over all modelPanels, find one that active (with gray contour) and ask for rendereName(rnm)

mel:

// find current modelEditor
string $cur_mp;
for ($mp in `getPanel -typ "modelPanel"`){
    // check if active
    if (`modelEditor -q -av $mp`){
        $cur_mp = $mp;
        break;
    }
}

if ($cur_mp != ""){
    // your coude next
    print $cur_mp;
    $new_rndr = "ogsRenderer";
    // set new renderer
    modelEditor -e -rnm $new_rndr $cur_mp;
}

py:

import maya.cmds as cm

cur_mp = None
for mp in cm.getPanel(type="modelPanel"):
    if cm.modelEditor(mp, q=1, av=1):
        cur_mp = mp
        break

if cur_mp:
    # do your stuff
    print cur_mp
    new_rndr = "ogsRenderer"
    cm.modelEditor(cur_mp, e=1, rnm=new_rndr)

pymel:

import pymel.core as pm

# maybe its not the best solution to iterate over all existing modelPanels
mp_ls = [x
         for x in pm.lsUI() 
         if type(x).__name__ == "ModelEditor"
         and type(x.getParent()).__name__ == "PyUI"
         and x.getActiveView()]

if mp_ls:
    # do your stuff
    print mp_ls[0]    # current modelEditor
    new_rndr = "ogsRenderer"
    mp_ls[0].setRendererName(new_rndr)

@Tomek's answer will perfectly work. If you are going the PyMEL route, you can do this:

import pymel.core.uitypes as pmui

model_panel = pmui.ModelEditor(pm.getPanel(withFocus=True))
print pmui.ModelEditor.getRendererName(model_panel)

Although, that snippet seems to be temperamental. It sometimes throws an error complaining that the model editor was not found, especially when executed from the shelf.

Another way would be a bit wordy, but it works everytime:

import pymel.core as pm
import pymel.core.uitypes as pmui

modelPanelList = []
modelEditorList = pm.lsUI(editors=True)
for myModelPanel in modelEditorList:
    if myModelPanel.find('modelPanel') != -1:
        modelPanelList.append(myModelPanel)

for modelPanel in modelPanelList:    
    if pmui.ModelEditor(modelPanel).getActiveView():
        try:
            # Always better to try in the case of active panel operations
            # as the active panel might not be a viewport.
            print pmui.ModelEditor(modelPanel).getRendererName()
        except Exception as e:
            # Handle exception
            print e

A concise, pseudo-PyMEL way would be to just PyMEL-ify Tomek's answer:

import pymel.core as pm
print pm.modelEditor(pm.getPanel(wf=True), q=True, rnm=True)

To get a list of viewport renderers:

import pymel.core.uitypes as pmui
print pmui.ModelEditor().getRendererList()

Here is some extra info on model editors and viewport renderers. To get their "friendly" names:

import pymel.core.uitypes as pmui
print pmui.ModelEditor().getRendererListUI()

To set them, concisely, I would use PyMEL and do:

import pymel.core.uitypes as pmui

# assuming you know which modelPanel you want to affect
pmui.ModelEditor("modelPanel4").setRendererName("ogsRenderer")

To affect all viewports (modelPanels) I would do:

import pymel.core as pm
import pymel.core.uitypes as pmui

modelPanelList = []
modelEditorList = pm.lsUI(editors=True)
for myModelPanel in modelEditorList:
    if myModelPanel.find('modelPanel') != -1:
        modelPanelList.append(myModelPanel)

for modelPanel in modelPanelList:
    pmui.ModelEditor(modelPanel).setRendererName("ogsRenderer")

To affect just the viewport in focus:

import pymel.core as pm
import pymel.core.uitypes as pmui

modelPanelList = []
modelEditorList = pm.lsUI(editors=True)
for myModelPanel in modelEditorList:
    if myModelPanel.find('modelPanel') != -1:
        modelPanelList.append(myModelPanel)

for modelPanel in modelPanelList:    
    if pmui.ModelEditor(modelPanel).getActiveView():
        try:
            # Always better to try in the case of active panel operations
            # as the active panel might not be a viewport.
            pmui.ModelEditor(modelPanel).setRendererName("ogsRenderer")
        except Exception as e:
            # Handle exception
            print e

This script returns renderer for focused panel:

import maya.cmds as cmds

print cmds.modelEditor( cmds.getPanel(wf=True), q=True, rnm=True )
