Hello, a short question. I have a function which is called, when a message is received. Than it puts the message into a channel with

(go (>! chan msg))

(go (println (<! chan))

@danielgrosse: so you’re sending multiple messages but only the first one gets printed out?

Yes. just discovered, I had to change it to

(go (while true (println (<! chan))))

yup

you also might wanna look into https://clojure.github.io/core.async/index.html#clojure.core.async/put!

friggin’ slack

that won’t work w/o the ! at the end

(see also https://github.com/clojure/core.async/wiki/Go-Block-Best-Practices, which i found super helpful)

What if i put continuous something into the channel without taking it out. Will it block anytime?

yep

well

depends on how you construct the channel

a plain (chan) will block first time every time

but you can set a length—`(chan 5)` will only block on the 6th item

there’s also like fancy sliding buffer stuff, but i don’t remember the details
