kandi X-RAY | ivi Summary
The IVI Specifications developed by the IVI Foundation provide standardized APIs for programming test instruments. This package is a partial, Go-based implementation of the IVI Specifications, which are specified for C, COM, and .NET. The main advantage of the ivi package is not having to learn the SCPI commands for each individual piece of test equipment. For instance, both the Agilent 33220A and the Stanford Research Systems DS345 function generators can be programmed using one standard API. The only requirement for this is having an IVI driver for the desired test equipment. Currently, ivi doesn't cache state. Every time an attribute is read directly from the instrument. Development focus is currently on fleshing out the APIs and creating a few IVI drivers for each instrument type.

QUESTION
I am trying to dynamically generate the following html table, as seen on the screenshot
I was able to manually create the table using dummy data, but my problem is that I am trying to combine multiple data sources in order to achieve this HTML table structure.
SEE STACKBLITZ for the full example.
The Data looks like this (focus on the activities field):

I can't seem to get Material Datepicker to accept the format I'm giving it. I want to format the date as YYYY-MM-DD, but it insists on using M/D/YYYY.
Below is a stack-blitz where I'm reproducing the issue. Additionally, it's putting the previous date selected, at the bottom of the HTML page seemingly unsolicited.

I've always been using the @ngx/json-ld package from Cory Rylan to render LD+json on my angular components. Today I tried upgrading my angular app to angular 12, but now it's giving errors. So I decided to create a new project with an angular library containing this component. The demo project in the same repository is working perfectly fine. But when I'm using my own library in my project I'm getting the same error as well.
Uncaught TypeError: Cannot read property 'ɵmod' of undefined
How can I solve this? Is this a problem with angular itself?

Answered 2021-May-29 at 08:38I don't know who posted the comment, but you were right. The installed package should contain the folders bundles

ing the wrong folder.
All I needed to do was change my workflow to publish package
= dist/path/to/package.json
instead of projects/path/to/package.json
.

I'm getting a weird bug in my program that is making the *ngIf stop working.

...ANSWER
Answered 2021-May-12 at 20:21As Stripe is a 3ed party tool and seems to not have any integration with Angular (judging on this line in Your repo when You are casting window
to any before getting access to Stripe
object) I would say this unexpected behavior is caused by running code outside of NgZone.
In a very simple terms - if Your code is calling some code as a callback of some external code, Angular might be not aware that the code was run. That means Angular is not aware of the fact some values changed -> it does not trigger change detection -> it does not refresh the page properly.
Why navigation is working? Because code in createToken
's callback navigates to https://www.howlingwolfe.com/thank-you
. And as URL changes, the matching component is used. Angular won't update the view but it will load a new component as URL changed.
Why console.log(this.isLoading);
is working? It is not a part of Angular to worry about updating values of the variables. Angular will not have any idea You changed the value but in the code You definitely changed it, so console.log
will be printing the proper value. It will be changed but Angular won't do anything about it if done outside of zone.
Now how to solve it: inject NgZone
to constructor and wrap entire of the code (so starting from line 109) in this._ngZone.run()
. You can follow the example provided in the docs.
Other issue might be that You are subscribing in the subscription. I do not have documentation here to back me up. The main reason would be that it gets tricky to unsubscribe from the inner subscription in a subscription (to be fair You should at least use takeUntil(unsubscribe$)
pattern for each of Your subscriptions (so ...pipe(takeUntil(this.unsubscribe$)).subscribe(...)
).
Next step would be to not having inner subscriptions - that's when higher observables come into play.
To give You an example, You should avoid doing it like this:
QUESTION
I would like to divide the window into two columns, one will have a mat-tab-group
, and the other one things.
To achieve this I want to use flexbox, but, when I set the parent display
as flex
, and the children's flex
as 2 and 1, if there is a mat-tab-group
, the child with the tab group expand totally to show all the tabs.
Here a stackblitz to have a better representation.
On the stackblitz, there is two test, the first one with the mat group, and the issue. The second one, without mat group but with what I want.
...ANSWER
Answered 2021-May-12 at 03:04If it is feasible for you to provide a max-width
rule to your mat-tab-group
parent container, that could help you work around this issue.

QUESTION
Hello my fellow developers!
So I've been working on this app for a while now. I like to be up to date with the frameworks I use, so I regularly update when the frameworks release a new version. i.e. Angular 9 > 10. Angular 10 > 11.
So I just recently updated to Angular 11 and updated my nestjs and nx. And now when I try to serve my frontend app, Ivy seems to complain a lot.. but a.. lot... about modules that are not used in the frontend app.
...ANSWER
Answered 2021-Mar-28 at 15:10After a day's review of the project, I was:
importing a class from the middleware that was using a library of the backend.
using a library from the backend in the frontend
To fix the issues also complies with best-practices.
I have split the class in the middleware into two classes: one for the frontend, one for the backend. I have refactored the code so that the backend library was not necessary on the frontend. I ended up just fixing two files. And all the errors dissapeared.
So if you encounter something similar, double check whether or not you use some backend libraries/classes in your frontend.

Answered 2021-Apr-06 at 07:40You probably have nulls somewhere in your dataframe, but not in the first 20 rows that you showed. That's why you got an error when counting the whole dataframe, but not when showing 20 rows from the dataframe.
To prevent nulls from crashing the program, change your udf to:
