Karate UI Framework : have to run a javascript to store chrome session to launch website [duplicate]

Firstly, Karate UI automation is really awesome tool. I am kind of enjoying it while writing the UI tests using Karate. I ran into a situation where in, i was trying to fetch the shadowRoot elements. I read few similar posts related to javascript executor with karate and learnt that it is already answered. it is recommended to use driver.eval. But in Karate 0.9.5 there is no eval, it has script() or scriptAll(). I have gone through documentation couple of times to figure out how i can fetch element inside an element but no luck.
Using traditional selenium+java, we can fetch shadowRoot like this way:
something like shadowRoot which sits inside a parent element like div or body.
//downloads-manager is the tagname and under that downloads-manager, a shadowRoot element exists
The HTML looks like this. it is from chrome://downloads.
<downloads-manager>
#shadow-root(open)
</download-manager>
WebElement downloadManager =driver.findElement(By.tagName("downloads-manager");
WebElement shadowRoot= (WebElement)((JavaScriptExecutor)driver)
.executeScript("return arguments[0].shadowRoot",downloadManager);
So i tried the following in Karate UI
script("downloads-manager","return _.shadowRoot"); //js injection error
script('downloads-manager', "function(e){ return e.shadowRoot;}"); // same injection error as mentioned above.
def shadowRoot = locate("downloads-manager").script("function(e){return e.shadowRoot};"); //returns an empty string.
I bet there is a way to get this shadowRoot element using Karate UI but i am kind of running out of options and not able to figure out this.
Can someone please look into this & help me?

Can you switch to XPath and see if that helps:
* def temp = script('//downloads-manager', '_.innerHTML')
Else please submit a sample in this format so we can debug: https://github.com/intuit/karate/tree/develop/examples/ui-test
EDIT: after you posted the link to that hangouts example in the comments, I figured out the JS that would work:
* driver 'http://html5-demos.appspot.com/hangouts'
* waitFor('#hangouts')
* def heading = script('hangout-module', "_.shadowRoot.querySelector('h1').textContent")
* match heading == 'Paul Irish'
It took some trial and error and fiddling with the DevTools console to figure this out. So the good news is that it is possible, you can use any JS you need, and you do need to know which HTML element to call .shadowRoot on.

Saving Hubot Input to a Variable

All I can find in the documentation is .hear("specific phrase"), or similar methods of processing input. Is there a way to simply store all input to the bot as a variable? The reason for this is that I intend on filtering this input through an NLP library to allow for natural language input to the bot. Any help is appreciated.
hubot on github.

I think what you're asking is if you can take what the person says to hubot, and put that into a variable. I do this with the following code:
module.exports = function(robot) {
robot.hear(/^(.*)/, function(msg) {
var content = msg.match.input;
});
}
Then, you can do whatever you want with the "content" variable. If you have any further questions, I'd be happy to answer them, assuming you haven't solved your problem already.

Ember, generating URL `url-to`?

I would like to generate a URL to a resource and show it to the User. I found the link-to but I don't want the whole <a> element but only the URL.
Something like:
{{#url-to 'photos.show' photo}}

I am not sure what Emberjs version you are using but in any case this may work for you. I haven't try my self but probably will help you.
{{#url-to 'photos.show' photo}}
Ember.Handlebars.registerHelper('url-to', function() {
return Ember.Handlebars.helpers['link-to'].apply(this, args);
});
Check this tutorial which goes more in details. Also you can search for how to create blocs helpers in emebrjs.

there is addon which adds such helper {{href-to}} have a look https://github.com/intercom/ember-href-to

Use directive as value for ng-if?

In my application, I need to be able to easily determine whether a user is authenticated within my HTML and in all templates.
My first thought on how to do this was to create a "global" controller and apply it to which simply set $scope.isAuthenticated = $auth.isAuthenticated.
However, after doing some reading, I discovered that this wasn't considered good practice. Instead, I created a directive, which would just return $auth.isAuthenticated().
angular.module('HordeWebClient')
.directive('isAuthenticated', function($auth) {
return $auth.isAuthenticated();
});
And then in my templates, I figured I could just use .... This doesn't work, the element isn't rendered regardless of the state of $auth.isAuthenticated.
The Safari error console doesn't show any problems, so I'm stuck on where to start in fixing this. Any pointers would be greatly appreciated.

In my opinion you should use .run on your main module.
angular.module('app').run(function(){
if(!isAuthenticated){
redirectToLoginView();
}
});

Querying the DOM in Windows 8 Apps from within a method

I'm struggling with this even after reading the MSDN documentation and the following online guides:

I think my problem is easy to fix and that I just am thinking about something in the wrong way. Basically I am querying my web service and on success running the following method. I am then trying to bind the result to my listview. For now I am using a hardcoded value publicMembers.itemlistwhich has been declared at the top of the document just to make sure I can actually bind to the list before doing it with my query results. Ignore line 2 for now.
Success Method:
_lookUpSuccess: function xhrSucceed(Result) {
var response = JSON.parse(Result.responseText);
listView = document.querySelector("#termTest");
ui.setOptions(listView, {
itemDataSource: publicMembers.itemList,
itemTemplate: document.querySelector(".itemtemplate"),
})
},
Now, instead of using document.querySelector, I have also tried with WinJS.Utilities.id and WinJS.Utilities.query, neither of which worked either. This doesn't break my code and introduce an error but it doesn't bind to the listview either so I think I have an issue in querying the right DOM element. However exactly the same code does work if I add it to the top of the script, it is only when I place it in this method that it stops working.
EDIT: Also to clarify, when I debug publicMembers.itemList is storing the values I expect them to be.
Please point out if I have explained things poorly and I will try and improve my question.
Thanks.

I haven't used WinJS.UI.setOptions, but rather this other way of setting the data source. Can you see if it works?
_lookUpSuccess: function xhrSucceed(result) {
var response = JSON.parse(result.responseText);
listView = document.querySelector("#termTest");
listView.winControl.itemDataSource = publicMembers.itemList;
},
This would assume you're defining the itemTemplate as part of the data-win-options attribute of your ListView's HTML element. You could also probably just do listView.winControl.itemTemplate = document.querySelector(".itemtemplate") if you prefer to set it programmatically.
