kandi X-RAY | lens Summary
User-friendly lens syntax for mortals. Update values inside of nested case class instances without .copy . Based on Monocle. Also see and . Use with caution. .copy and likewise .lens can make code hard to read. They are conceptually creating patched versions of existing objects. It can be hard for readers to reason about the patching, similar to how it is hard to reason about mutation. If you can write your code in a way that does not need patching objects, prefer that. If you can't, .lens is a nice alternative to .copy.

QUESTION
Lets say I have a simple console program where user can input some text. And suppose I have class as follows:
...ANSWER
Answered 2021-Jun-14 at 10:34I'm sensing some anti-patterns here. The key thing you're looking to do based on your question is set the user's input to the name of a variable - of an instance of your class. I don't know if that's necessarily the best way to do it for your use case. Maybe it could be better to always name the variable the same thing but add a self.string parameter to your A class.
If you do want to do that see here. You would write

I am fairly new to opencv and image editing, self learner you can say. I wanted have a poc of text morphing in videos like it happens with google lens but with the help of opencv.
I have achieved that for single video single run, but what I want to do is to take one input video, process it for the given positions of frames, save the output, then take that processed output as input for the next iteration and then save it after new edits are made.
I am trying to take data from a json file, which looks like this.
Here is link to my code. I am a complete newbie trying to learn, so my methods and approch might be highly inefficient but I would appreciate any help.

Answered 2021-Jun-06 at 09:54when you read the video till the end, it doesnt just reset.
so you need to reset the video on every loop. either open the videocapture again. move cap = cv2.VideoCapture(video_original) inside your loop for document in range
or set the frame to whatever start frame (eg 0) you want using cap.set(cv2.CAP_PROP_POS_FRAMES, self.frame_num) inside your loop
QUESTION
New to Nuxt and SSR. What I'm trying to do is straightforward: I'm trying to trigger a function before the page loads that will SSR my firestore data. If I add a button with @onclick, it works fine. But when I try to replace the Button/OnClick with @onloadstart or something similar, nothing happens.
What am I missing? I suspect I’m thinking about this through a client side lens. Not a SSR lens.
...ANSWER
Answered 2021-Jun-04 at 19:58You're close to a working solution in terms of having the component automatically fetch data before the page loads. Instead of beforeCreate, you'd use the asyncData hook (which seems to be your initial attempt).
The problem is you've declared asyncData as a component method, but it needs to be at the top level of the object definition for it to be used as a component hook.

I would like to be able to combine two tuples of the same length using a function, similar to the zipWith function from base.
For example, for the case of length 3 tuples:
ANSWER
Answered 2021-Jun-02 at 03:53I know you asked for a lens-based approach, but if you only have small tuples, you can implement what you want with a type class without too much trouble. Consider for instance:
QUESTION
I am trying to find code lens support for python in visual studio code. I am having many methods which are not used. Using 'find all references' for each method is time consuming and tedious. If code lens facility there and show number of references for each method, it would be easier to clean up unused methods.
Can code lens be enabled for python in vscode ? Sample code lens is given below

Answered 2021-Jun-04 at 02:27It seems the team doesn't want to move forward with this idea.
Some people have put forward this feature request, but the team thought there isn't an enough widespread need for this to warrant the maintenance cost for the feature.
You can refer to here and here to check the discussions of this feature request talking in the early.
While the JavaScript, TypeScript and C# extension has this feature. As you can enable it with:

Answered 2021-Jun-02 at 15:35Json.NET does not have any support for the types in the Windows.Data.Json namespace, so you will need to create a custom JsonConverter for JsonObject as well as JsonArray and JsonValue if you ever use those classes directly. The following should do the job:

I have an issue on my deployment when I try to share a folder with a kubernetes volume. The folder will be shared using an Azure File Storage. If I deploy my image without sharing the folder (/integrations) the app start. as shown in the image below the pod via lens is up and running
If I add the relation of the folder to a volume the result is that the pod will stuck in error with this messagge
Here I put my yaml deployment:
...ANSWER
Answered 2021-May-24 at 02:06Well, there are two things I think you need to know when you mount the Azure file to the pods existing folder as the volume:
- it will cover the existing files
- the mount path will set the ownership as the root user
So the above means if your application will start depends on the existing files, then it will cause the problem. And if your application uses a non-root use, for example, the user app, then it maybe will also cause the problem. Here I guess the problem may be caused by the first limitation.
