Re: [Haskell-cafe] Help to choose a library name

Wow, it is very impressive. I need to give it more time. I have one question regarding this example: main = keep $ do th <- liftIO myThreadId -- thread 89 r <- async (do threadDelay 1000000; return "hello") -- thread 90 <|> async (return "world") -- thread 91 th' <- liftIO myThreadId -- thread 90 and 91 liftIO $ print (th, th', r) -- thread 90 and 91 Output: (ThreadId 89,ThreadId 91,"world") (ThreadId 89,ThreadId 90,"hello") For me it's counter-intuitive that there are two outputs. What is the reason behind? It seems that the use of the <|> affects the rest of the program. It looks strange to me because the two lines situated after the <|> does not look "syntactically" involved, if you see what I mean. Instead I was expecting only one output, with the first thread to finish "wins". In fact I implemented it like that: http://www.corentindupont.info/blog/posts/Programming/2014-09-23-Nomyx-Langu...

Hi! Have you looked at Transient by Alberto Gomez Corona?

Hi Joachim, I agree... I looked hard at them :) https://wiki.haskell.org/Functional_Reactive_Programming

I need a library with a DSL able to create forms on the fly, in a "demand driven" way. I.e. if at some point in time the user program needs a boolean from the user, a radio button will be created on the screen of that user. The objective is to retrieve the boolean, creating the form is just a way to do that. Complex forms can be created, capable of generating full ADTs. The styling of the form is not important. Other requirements: - it should be possible to run the event DSL in a monad different from IO. - the event DSL need to be instance of Alternative: events can be put in concurrence, the first to fire wins.

I need it for the game Nomyx, but couldn't find the features I wanted from the existing libraries.

any chance to extend existing libraries to support what you need? Library proliferation does not really help the ecosystem.
