How to detect the completion of a Tcl coroutine?

别来无恙 提交于 2021-02-07 21:49:48
问题 I'd like to find a nice way in Tcl to detect the end of a coroutine. Consider: coroutine cor apply {{} { yield 1 yield 2 yield 3 }} try { puts [cor] puts [cor] puts [cor] puts [cor] } trap {TCL LOOKUP COMMAND cor} {e} { puts "done" } This works, but it feels like a hack and it is brittle. If I rename cor and forget to rename it in the trap, it fails. If I leave out the cor in the trap, it will catch unrelated typos. There's got to be a better way. What is it? 回答1: To detect if a command still

Wait for coroutine to finish [duplicate]

问题 This question already has an answer here : More organized way to call Coroutines? (1 answer) Closed 3 years ago . I have coroutine that after N seconds clear text and returns it to it's original shape. Problem is that coroutine never continues after first return ( wait for seconds ). I had this problem somewhere else and figured it out that is happening because i destroy Gameobject before coroutine finish so i made it return bool but now i am confused and can not use same trick here since i

Python loop in a coroutine [closed]

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 8 years ago . I've read all the documentation on the subject, but it seems I can't grasp the whole concept of Python coroutines well enough to implement what I want to do. I have a background task (which generates some random

Handling hundreds of routes in Vert.x best practices

问题 Please have a look at the piece of code below. Now suppose i'll have hundreds of entity like "person". How would you code such a thing to get it clean, concise, efficient, well structured ? Tx class HttpEntryPoint : CoroutineVerticle() { private suspend fun person(r: RoutingContext) { val res = vertx.eventBus().requestAwait<String>("/person/:id", "1").body() r.response().end(res) } override suspend fun start() { val router = Router.router(vertx) router.get("/person/:id").coroutineHandler {

Exception throw in boost::asio::spawn not caught by try catch

≡放荡痞女 提交于 2021-01-28 05:14:31
问题 In this convoluted example, two for loops are started by boost::asio::spawn() asynchronously. The first for loop prints an odd number every 1000us and the second one prints an even number every 1000us. I expect the output to be something like 1 2 3 4 5 6 and then the 'Throw an error' message should be printed to stderr by the call to cerr. However, the exception is actually thrown in loop.run() so it is not caught by the try catch block. Can someone point out how to properly catch the runtime

问题 I'm adding support for coroutines ts in an async socket class based on windows io completion ports . Without coroutines the io may be done like this : sock.async_write(io::buffer(somebuff), [](auto&& ... args){ /* in handler */ }); or sock.async_write(std::vector<io::const_buffer>{ ... }, [](auto&& ... args){ /* in handler */ }) where each one will returns void and will notify the result through the handler and doesn't need to cache the parameters because the operation will have been

Convert callback hell to deferred object

问题 Background : So, I have a pretty big project with a lot of API functions. I'm thinking of completely moving to coroutines, but as they are implemented as Callback and not Deferred , I can not use them efficiently. For instance: I would like to do apiCallOne() , apiCallTwo() and apiCallThree() async and call .await() to wait till the last request is completed before changing UI. Now the project is structured like this: At the very bottom (or top) is ApiService.java : interface ApiService {
