Clojurians Log v2

removed my message for a more relevant channel

This is the create-subscription function:

(defn create-subscription [req]
  (prn "request is " (:params req))
  (prn "payment method is " (:payment-method-id (:params req)))
  (let [customer (cust/create {"email" (:email (:params req))
                               "payment_method" (:payment-method-id (:params req))
                               })
        subscription (esub/create customer {"items"
                                            [{"price" (:price-id (:params req))}]
                                            "expand" ["latest_invoice.payment_intent"]})]
    (prn "subscription is " subscription)
    )
  (req-res/response "response"))

and the error is in the cust/create

in the docs under create a customer, there’s a payment_method parameter @dsp

which is what I have as well

I have the following question posted in clj-http: https://clojurians.slack.com/archives/C8860D6BS/p1613018229002500 Your help is much appreciated!

if that's real data you might have a bit of a headache

@dpsutton what do you mean by real data? It’s key value pairs where values are strings

He means that :basic-auth string I think...

That auth seems real (although the customer ID seems invalid)

You might want to delete that message @ps although at this point it's probably been archived to the logging site -- not sure if it respects deletes. The Zulip bot does respect deletes so it will at least remove it from there.

The #clj-http channel at least is not logged/archived as far as I can tell so at least it's only in this channel -- and Zulip doesn't copy the body of shared messages. Not sure if logbot does.

@ps You could try :body "customer= cus_IvNWjfw1q2clxS" in the post request. It’s equivalent to --data-raw option in curl IIRC.

Thanks

Hello i am testing a maven project,where Clojure code is also inside the maven. It works fine , but i want to use a class from Clojure code gen-class , and it said it cant find it

in lein, i did :aot but in maven i dont know what to do to find it

normal call clojure from Java works IFn etc , but i want a class

you can use https://github.com/talios/clojure-maven-plugin for that

it hooks into the compile phase to compile clojure code

it does it automatically? or i have to set settings

you'll have to configure your pom to make that happen

thank you i will try it now 🙂

the readme has more info

anyone know of a good transducer that kinda sorts? Ideally holds onto the largest N items by some metric?

and not sorts but just retains the largest values, not necessarily sorted

(transduce (biggest 5 identity) conj [] (range 30) would build up a collection no more than five at any point in time as it reduced the collection

@dpsutton I think you can look at a transducer like distinct and then adapt it

good point. thanks @borkdude

you could probably use https://github.com/cgrand/xforms window transducers

yeah i'm not familiar with his excellent library so i was hoping it would ring a bell as something already done with a proper immutable min heap

by which i mean thanks for pointing me towards window!

lots of other useful things there too

yeah. i've never delved in and its probably time. thanks

I need a TCP client library. I just want to send bytes and receive bytes. Aleph has exactly the kind of interface I'm looking for:

(def client @(aleph.tcp/client {:host host :port port}))
(manifold.stream/put! client (msg->bytes mx))
(bytes->str @(manifold.stream/take! client))

https://docs.oracle.com/javase/7/docs/api/java/net/Socket.html

https://docs.oracle.com/javase/tutorial/networking/sockets/index.html

sockets appear to form part of the https://github.com/clj-commons/byte-streams abstraction. Not very familiar with it though

the java socket stuff is pretty easy to use via interop, you don't really need a library for it

on one side you mostly just create a ServerSocket and .accept on it, which gives you a connection, which has an input/output stream on the other, create a new socket and use its input/output stream

pretty basic example: https://www.baeldung.com/a-guide-to-java-sockets

cool I'll give it a shot with sockets. I've used them a bit before but this time I got hung up on some (java) example code using Nio socketchannels and was trying to do it in that way which maybe has a bit more of a learning curve.

that's a couple more steps (but opens some new options)

I'm writing a clj wrapper for https://bitbucket.org/chromiumembedded/cef/ (cef) and am trying to figure out the best way to make it consumable as a library. The cef framework by itself is 80MB compressed and ~220MB uncompressed which seems too large to include in a library jar. Currently, I'm putting everything except the cef framework in the library jar and including a function that will download/extract the framework if it doesn't exist on the local file system. Is there a better way to handle this?

@smith.adriane I think that's a good tradeoff

This will maybe also allow your tool to upgrade CEF itself without upgrading the jar, might add some flexibility.

Or if users already have it, they could maybe set some env variable to indicate where it is

supporting env variables would make a lot of sense. Currently, I only allow the consumer to specify the target dir, but supporting env variables at some point would also be good.

was asking about a biggest-by transducer earlier but realized i needed a reducing function for this actually. Does anything about this stand out as problematic?

(fn queue-accumulator
  ([] (PriorityQueue. 30 cmp)) ;; custom comparator
  ([^PriorityQueue q]
   (loop [acc []]
     (if-let [x (.poll q)]
       (recur (conj acc x))
       acc)))
  ([^PriorityQueue q item]
   (if (>= (.size q) threshold)
     (let [smallest (.peek q)]
       (if (pos? (.compare cmp item smallest)) ;; custom comparator
         (doto q
           (.poll)
           (.offer item))
         q))
     (doto q
       (.offer item)))))
