Morning Everyone!

You can always easily identify the people with young children 😂 Morning o/

🙂

My good start of the day is that the latest slack client has reverted that horrible rich text editor, you can enable previous editing, using markup, now!

preferences...`advanced`...ensure that format texts with markup is ticked.

Fabulous! Pity you have to set that for every single workspace you use in Slack tho'...

indeed, but luckily it carries forward to each slack instance, i.e., if you have a work machine and a laptop with slack on them both

I always wondered why there isn't a "meta" preferences that applies globally. I sometimes think that Slack exploded in popularity and the original intent was lost and having multiple workspaces with a global preferences didn't really make the cut originally.

Yeah, they have all sorts of weird cross-workspace features but they don't really help you if you have multiple independent workspaces...

indeed

Right - bbl - kid is demanding to be fed - how selfish! 😉

Anyone been watching Castle Rock (Hulu)? Does it eventually make sense?

The new interface encouraged me to use ripcord again

Morning

reClojure inspired me to take a proper look at shadow-cljs I appreciate that the npm integration is a Really Good Thing - I'm not sure what else it does better than Figwheel though. What are the other reasons to choose shadowcljs?

Hello nice and on topic question. Anyone know a very good gastropub type restaurant for a cosy christmas dinner anywhere along the line between London to Milton Keynes

Was hoping some of our resident Milton Keynes members might know.. :p

When you say between London to Milton Keynes, what do you mean exactly? :)

The Red Lion in Hemel Hempstead

Takes a bit of a drive though, it isn't near the station

But the food is outstanding

There's another branch in Berkhamsted within walk of the station (maybe 10 minutes?), still pretty solid but not quite as good IME.

The Berkhamsted branch is The King's Arms, the chain is Oakman Inns

@dominicm - What's "ripcord"?

@seancorfield - Is that the Inspired by Stephen King show..? I have been really wanting to watch that...

Hey y'all, I am hoping that I am doing something dumb, but... I have this code:

response @(http/post
                   api-url
                   {:headers {ECMWF-API-Key-Header ECMWF-API-Key
                              ECMWF-From-Header ECMWF-API-Key-From}
                    :body json-data-request
                    :content-type :json
                    :accept :json})]

when I run (type response) I get aleph.http.core.NettyResponse like I expect, but if I try to pick it apart all I get is errors... Eventually I (println response) and I just get a number. A couple of days ago this code was working... 😞

Anyone got any idea(s) as to how I am being stupid?

what’s this?

{ECMWF-API-Key-Header ECMWF-API-Key
 ECMWF-From-Header ECMWF-API-Key-From}

It is worth mentioning that the API in question is successfully queueing my request(s), I am just not able to interrogate the response in the way that I was...

(p/def-derived-map NettyResponse [^HttpResponse rsp complete body]
  :status (-> rsp .status .code)
  :aleph/keep-alive? (HttpUtil/isKeepAlive rsp)
  :headers (-> rsp .headers headers->map)
  :aleph/complete complete
  :body body)

looks like it’s a derived-map

https://github.com/ztellman/potemkin

so it’s just calling the underlying HttpResponse object

do any of those keys work?

nope - and yet responses I get from http/get do have those keys

not even :status ?

Nope I get nil

lol

I am starting to wonder if the API is actually sending a bad response / is broken.

going to check in an API client...

what is the value of :key-set##?

that’s the raw underlying object

I think I know what is going on...

I am attempting to force the delivery of the defferred by using @ and doing it inside a (let...)

If I run the (http/operations in my REPL they get delivered, albeit slowly (150-200 ms)

When I test the whole function(s) when the http requests are being made and I am trying to bind them to a local var in a (let ...) then for some reason they are transformed into a number...

are you not allowed to do that?

I thought it’d just block until delivery?

;; A future's calculation is started here and it runs in another thread
user=> (def f (future (Thread/sleep 10000) (println "done") 100))
#'user/f
;;if you wait 10 seconds before dereferencing it you'll see "done"

;; When you dereference it you will block until the result is available.
user=> @f
done
100

So did I, but it does seem to be doing something weird. As I say, the actual http/ calls work in my REPL and indeed the REPL blocks until they are delivered.

Clojure 1.10.1
user=> (def f (future (Thread/sleep 10000) (println "done") 100))
#'user/f
user=> (let [g @f] (println f)
done

@cfeckardt - It's not a plain future, it's a manifold deferred (aleph uses manifold under the hood), and this is where I am wondering if there is a difference...

I am going to try just a "toy" version in my REPL with a Manifold Deferred and see what happens...

(I still think that I am just doing something dumb and I can't see the wood for the trees)

@maleghast derefing a manifold deferred is fine from a sync code context... don't do it from inside deferred/chains though (you can cause deadlocks)

Yep, I got to the bottom of it... I am going to slink off into the corner and ask you all to pretend I never posted any of this ^^

Suffice it to say that I was just being a dumbass - sorry for the distraction...

we're all dumbasses pretty much all the time aren't we ? or am i just projecting ?

I think so, and it’s a good place to be, means we’re all learning more at the same time.
