Has anyone dealt with the Microsoft Graph API, just looking for some pointers on getting started with it. Fairly new to Clojure.

I haven't but I can probably help you with using the Java library

https://github.com/microsoftgraph/msgraph-sdk-java

quick google came up with this

For the curious, tried the new a1 (arm64) gen machines on aws with ubuntu linux, java and clojure work nicely :)

(from the readme)

making the same call from clojure would look like this

and the next call on there for getting the users drive

the equivalent clojure would be

(those snippets cover quite a few clojure idioms and features, so feel free to ask for more info)

have anyone here used clojure with opengl or similar? I'm having a hard time finding information about how to go on about it

Hi guys, I'm using the AWS Java SDK V2 and am getting IllegalArgumentException Can't call public method of non-public class: public final java.lang.String software.amazon.awssdk.core.BytesWrapper.asUtf8String() throws java.io.UncheckedIOException clojure.lang.Reflector.invokeMatchingMethod (Reflector.java:88) when trying to access the public functions of a non-public super-class of an object. specifically: I'm using the getObject method on an S3AsyncClient object with the ByteArrayAsyncResponseTransformer to get on object as a byte array. the returned value is an object from the public class ResponseBytes that extends the BytesWrapper abstract (non-public) class. But because of the reflection implementation of Clojure, I'm unable to access any of the public methods of BytesWrapper (such as asUtf8String). Do you guys know of anyway to access these super methods?

@eyal.shalev i've hit this problem before - iirc you have two options - [1] is to write some java which exposes an interface you can call from clojure and [2] is hacky but doesn't require any java and is to override the access modifiers (assuming your SecurityManager permits it) https://docs.oracle.com/javase/8/docs/api/java/lang/reflect/AccessibleObject.html

What version of Java and Clojure?

Java version 1.8 Clojure version 1.9.0

Did you try type hinting to the public class to remove reflection?

Yes

Not sure if there is a bug here or not, would be great to have a ticket with more details

the bug i was hitting a while back was : https://bugs.java.com/bugdatabase/view_bug.do?bug_id=4283544

although looking at the problem i hit it was the other way around from @eyal.shalev’s problem (package private impl inheriting from public interface), so may be a similar looking but different issue: https://github.com/nats-io/java-nats/pull/35

Hey guys, why isn't javax.websocket extension available to me? I'm trying to import it but without any success.

I am trying to get a Clojure/Leiningen project going on a Windows 10 machine (was using Mac). I installed the Linux Subsystyem (Ubuntu) and I am connecting remotely to the REPL that is running inside the subsystem. It seems a little slower but it works. What doesn't work though is when I edit a file. I generated the project using Compojure template so it has autoreloading enabled. When I edit a file I get: java.io.FileNotFoundException: Could not locate ring/mock/request__init.class or ring/mock/request.clj on classpath., compiling:(myproject/handler_test.clj:1:1). The project auto reloads reliably on Mac - Any idea what is wrong and how to fix it?

I found the solution here https://github.com/technomancy/leiningen/issues/1666#issuecomment-131562170 ... still not sure why it was working fine on Mac though.

have you guys been seeing this error lately at all?

Caused by: clojure.lang.ExceptionInfo: Call to clojure.core/ns did not conform to spec:
In: [0] val: nameofproject.core/-dev-main fails spec: :clojure.core.specs.alpha/ns-form at: [:args :name] predicate: simple-symbol?

i commonly use a -main and -dev-main like this

(defn -main
  ([]     (-main 8000))
  ([port] (jetty/run-jetty app
                           {:port (Integer. port)})))

(defn -dev-main
  ([]     (-dev-main 8000))
  ([port] (jetty/run-jetty (wrap-reload #'app)
                           {:port (Integer. port)})))

but that error is about your ns form

if i merely comment out this line in my :dev profile it doesn’t complain

:main nameofproject.core/-dev-main

wait, that's in your ns form?

Just watched Stu's talk on REBL and would love to spend the afternoon messing around with it. Does anyone know when/where the early access will be made available?

Very soon

@alexmiller Awesome, I wasn't sure if it had already been published and I just wasn't looking in the right place. I've already extended the datafy and nav protocols to some stuff in a side project I'm working on, and I'm curious to see how it works with the REBL browser (or if I've even do it correctly).

Is this a Mac-only app?

Says JavaFX so probably cross-platform?

hello guys

seems the function args is evaluated before pass to the function

is there a way to fix this or should i think in another approach ?

the macro args are evaluated after they are returned by the macro

but at compile time

(defn foo [l] (type-0 l)) CompilerException java.lang.IllegalArgumentException: Don't know how to create ISeq from: clojure.lang.Symbol

the macro args are not evaluated before the macro runs, so if your macro needs a collection, it needs a literal collection as an input

you mean ["hello" "world"] ?

why are you macroing? just so you don’t have to quote your symbols ?

@abdullahibra or [hello world] like in your example

macros are for transforming an input form into a new form to be compiled

they can't operate on data that isn't known when compiling

Good, thank you 🙂

said something wrong at first - now I see why you need quoting there

@abdullahibra oh - double correction - not only does it work without ~@ - it works without using quoting at all

ins)user=> (defmacro type-0 [l] (mapv str l))
#'user/type-0
(ins)user=> (type-0 [a b c])
["a" "b" "c"]

but it's good to use ` so that mapv and str are fully qualified in the result

that's doing the mapv str at compile time, qualifying doesn't mean anything

they're resolved by the runtime, after macroexpansion the mapv expression doesn't exist anymore

oh - fair, so there's no hygeine issue

user=> (defmacro type-0 [l] (mapv str l))
#'user/type-0
user=> (defmacro type-0' [l] `(mapv str '(~@l)))
#'user/type-0'
user=> (macroexpand '(type-0 [a b]))
["a" "b"]
user=> (macroexpand '(type-0' [a b]))
(clojure.core/mapv clojure.core/str (quote (a b)))

REBL looks cool, but I'm curious if it will continue to be closed-source. I realize no one here may know or be able to answer.

i would imagine. i'm totally ok with using a quality closed source product. basically every webapp (including this one) is like that

Does anyone know how to run REBL inside cider/nrepl? nrepl is mentioned in the README

did we get an answer on the "can I use it while while at my day job as long as I don't embed REBL" question?

issue open on GH, mentioned in #off-topic, it's on HN and reddit. no clarification

People are busy with the conf, so give them some time. My personal belief is that the intention is for anyone to be able to use it

But that is not an official answer

understood. it is still release candidate anyways 🙂
