Dispatch | Just a tiny library to make using GCD | iOS library

You can do this as a reduction over foldernames using getattr to dynamically get the next attribute.

A few notes:

• job callbacks accept exactly one argument of type CallbackContext. Not two.
• the job_kwargs parameter is used to pass keywoard argument to the APScheduler backend, on which JobQueue is built. The way you're trying to use it doesn't work.
• if you want to know only the chat_id in the job, you don't have to pass the whole context argument of search_msgs. Just do context.job_queue.run_once(..., context=chat_id,...)
• if you want to pass both the chat_id and context.args you can e.g. pass them as tuple:

Send your data to separate processes. I used concurrent.futures because I like the simple interface.

This runs in about 11 seconds on my computer.

I'm not familiar with Discord bots but I don't think your endHandler will ever run the else if part the way it is because your code is always creating a new dispatcher when it plays the next song, but never sets up a finish handler for it.

It looks like you have problem in mapStateToProps

This is exactly the reason why coroutines were invented and how they differ from threaded concurrency. Coroutines don't block, but suspend (well, they can do both). And "suspend" isn't just another name for "block". When they suspend (e.g. by invoking join()), they effectively free the thread that runs them, so it can do something else somewhere else. And yes, it sounds like something that is technically impossible, because we are in the middle of executing the code of some function and we have to wait there, but well... welcome to coroutines :-)

You can think of it as the function is being cut into two parts: before join() and after it. First part schedules the background operation and immediately returns. When background operation finishes, it schedules the second part on the main thread. This is not how coroutines works internally (functions aren't really cut, they create continuations), but this is how you can easily imagine them working if you are familiar with executors or event loops.

delay() is also a suspending function, so it frees the thread running it and schedules execution of the code below it after a specified duration.

What can I do to ensure that it's only called once?

Nothing, that's how it's meant to work. In the View system you would not ask "Why is my view invalidated 3 times?". The framework invalidates (recomposes) the view as it needs, you should not need to know or care when that happens.

The issue with your code is that your Composable is reading the old value from preferences, that is not how it should work, that value should be provided by the viewmodel as part of the state. Instead of providing just the new price, expose a Data Class that has both the new and old price and then use those 2 values in your composable to determine what color to show, or expose the price and the color to use.

I had the same problem and I found a workaround here at https://github.com/jekyll/jekyll/issues/8523

Add gem "webrick" to the Gemfile in your website. Than run bundle install

At this point you can run bundle exec jekyll serve

For me it works!

It is a separate thread, you're just asking the current thread to invoke the code on the EDT and wait until it has been executed.

It's just like starting a thread explicitly:
