QUESTION
This question is about two MAUI controls (Switch
and ListView
) - I'm asking about them both in the same question as I'm expecting the root cause of the problem to be the same for both controls. It's entirely possible that they're different problems that just share some common symptoms though. (CollectionView
has similar issues, but other confounding factors that make it trickier to demonstrate.)
I'm using 2-way data binding in my MAUI app: changes to the data can either come directly from the user, or from a background polling task that checks whether the canonical data has been changed elsewhere. The problem I'm facing is that changes to the view model are not visually propagated to the Switch.IsToggled
and ListView.SelectedItem
properties, even though the controls do raise events showing that they've "noticed" the property changes. Other controls (e.g. Label
and Checkbox
) are visually updated, indicating that the view model notification is working fine and the UI itself is generally healthy.
Build environment: Visual Studio 2022 17.2.0 preview 2.1
App environment: Android, either emulator "Pixel 5 - API 30" or a real Pixel 6
The sample code is all below, but the fundamental question is whether this a bug somewhere in my code (do I need to "tell" the controls to update themselves for some reason?) or possibly a bug in MAUI (in which case I should presumably report it)?
Sample codeThe sample code below can be added directly a "File new project" MAUI app (with a name of "MauiPlayground" to use the same namespaces), or it's all available from my demo code repo. Each example is independent of the other - you can try just one. (Then update App.cs
to set MainPage
to the right example.)
Both examples have a very simple situation: a control with two-way binding to a view-model, and a button that updates the view-model property (to simulate "the data has been modified elsewhere" in the real app). In both cases, the control remains unchanged visually.
Note that I've specified {Binding ..., Mode=TwoWay}
in both cases, even though that's the default for those properties, just to be super-clear that that isn't the problem.
The ViewModelBase
code is shared by both examples, and is simply a convenient way of raising INotifyPropertyChanged.PropertyChanged
without any extra dependencies:
ViewModelBase.cs:
...ANSWER
Answered 2022-Apr-09 at 18:07These both may be bugs with the currently released version of MAUI.
This bug was recently posted and there is already a fix for the Switch to address this issue.

I have created this file called main.ts:
...ANSWER
Answered 2021-Sep-26 at 13:34Your issue is related to interoperability between TypeScript/ECMAScript modules and CommonJS.
When it comes to the differences between ECMAScript modules and CommonJS modules:
- CommonJS modules are meant to be imported like
const library = require('library')
which allows to retrieve the fullexports
object of that library. There is no notion of default import in CommonJS - ECMAScript modules have explicit
export
clauses for every exported item. They also feature a default import syntax which allows to retrieve thedefault
export in a local variable.
In order to implement interoperability between CommonJS modules and TypeScript's default import syntax, CommonJS modules can have a default
property.
That default
property can even be added automatically by TypeScript when esModuleInterop
is enabled (which also enables allowSyntheticDefaultImports
). This option adds this helper function at transpilation time:
QUESTION
Below is the code. I understand applicative, functor, traversable and monad to a certain extent. The iterator and yield types, and yield functions are what I struggle understanding the most. For example, what are i o r in Iterator and i o r a in Yield? what does traverseY do exactly and what do the signatures mean? and How Monad Cont is applied here also confuses me a lot. Thank you for reading, any input would be appreciated.

represents a process that repeatedly takes a value of type i
and outputs a value of type o

Answered 2021-Jul-28 at 07:22You are running the project via Java 1.8 and add the --add-opens
option to the runner. However Java 1.8 does not support it.
So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.
Another solution is to find a place where --add-opens
is added and remove it.
Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine

It has been almost a year since I saw Jonathan Worthington presenting the new RakuAST in the YouTube video A Raku API to Raku programs the journey so far from TRC 2021. In the video, he showed that we could dump this new RakuAST using RAKUDO_RAKUAST=1

I have an array of positive integers. For example:
...ANSWER
Answered 2022-Feb-27 at 22:44This problem has a fun O(n) solution.
If you draw a graph of cumulative sum vs index, then:
The average value in the subarray between any two indexes is the slope of the line between those points on the graph.
The first highest-average-prefix will end at the point that makes the highest angle from 0. The next highest-average-prefix must then have a smaller average, and it will end at the point that makes the highest angle from the first ending. Continuing to the end of the array, we find that...
These segments of highest average are exactly the segments in the upper convex hull of the cumulative sum graph.
Find these segments using the monotone chain algorithm. Since the points are already sorted, it takes O(n) time.

After taking a step back, I realized that I could try out what I did to fix the sass-loader
issue: downgrading major versions.
Steps
- Downgraded
style-loader
1 major version to2.0.0
:npm i style-loader@2.0.0
- Then, as luck would have it, I ran into the same issue with
css-loader
- Downgraded
css-loader
1 major version to5.2.7
:npm i css-loader@5.2.7
Summary
By downgrading all of the loaders one major version, I was able to get it to work.

Install tree
You can use tree like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
