anybody used google apis with clojure, especially youtube? I need to upload videos programmatically and already started doing it with the java libraries, but oh dear god, there are so many types... didn't find any good pure clojure wrappers, anyone?

@kaosbeat I've worked with this one for Google docs. Especially the authentication part felt smooth (openin a browser window for you etc) https://github.com/SparkFund/google-apps-clj

Does someone have experience with instaparse and (external) bnf grammars? I was thinking to use instaparse with an AWS grammar, but it is not compatible https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_grammar.html#policies-grammar-bnf

Hello, i've came across one strange behavior:

(defprotocol A (-a [_]))
(def a -a)
(extend-protocol A Object (-a [x] x))
(a {}) ;; => No implementation of method: :-a ....

that makes sense

when you do (def a -a), you're assigning to a the dereferenced value of -a at the point in time of the assignment

i should use #'-a

yep

ok isee

thank you

Clojure:

user=> (.replace "foo" "o" "x")
"fxx"

cljs.user=> (.replace "foo" "o" "x")
"fxo"

it's a bit of an internal detail that extend-protocol works by resetting the root binding of the method vars

but not a bug

ok nice to know

is there a valid syntax for doing something like that? (ns foo (:refer-clojure :exclude :all) (:require [clojure.core :as c]))

is that invalid?

it seems, i will double check

CompilerException java.lang.IllegalArgumentException: Don't know how to create ISeq from: clojure.lang.Keyword

(ns foo ...)

yes sorry, this is not the problem

Oh, I just realised :exclude :all.

i have to use :only

with empty vec i think

Is there a way to create a global var in the same fashion as *warn-on-reflection* on which I can call (set! *my-var* true)?

When I do it like (def ^:dynamic *my-var* false) and then do (set! *my-var* true) I get IllegalStateException Can't change/establish root binding of: *my-var* with set clojure.lang.Var.set (Var.java:221), presumably because it is a local binding, as mentioned here: https://clojuredocs.org/clojure.core/set!

the reason why you can set! *warn-on-reflection* is that the evaluation context of clojure has *warn-on-reflection* local-bound, it's not a "special" type of Var

so no, without an existing thread binding you just can't set! a var

you can alter-var-root it

but that's a different operation

(set! *warn-on-reflection* true)
=> true

what about that?

>the evaluation context of clojure has *warn-on-reflection* local-bound by that I meant that there is an implicit (binding [*warn-on-reflection* *warn-on-reflection*] ..) wrapping your repl session

there's a handful of clojure.core Vars that get that special treatment of being thread-bound by the compiler environment

but there's nothing special about the Vars themselves

a Var has to be thread-bound if you want to set! it

makes sense

Perhaps I should describe what I'm trying to accomplish. I am writing a library that has a Java-consumable interface. I'm wanting to provide a setting that will disable a specific validity check, if needed, for performance reasons. I'd like it to be possible to set this permanently or as a binding, if possible.

It would be unwieldy to have to wrap your entire app in a binding to disable it globally - especially from Java where you'd likely have to pass your entire program logic in as a Runnable or something

However, I can see there being cases where you might want to disable the setting for one use case while preserving it for others

thanks @jeroenvandijk hmm it really wraps Google's java client apis and no youtube, but looks fairly complete. youtube's inserting must be pretty similar to drive insert.. perhaps I should add to that

might you guys have a solution for a java.lang.NullPointerException each time to try evaluating an expression while in a breakpoint window, using Cursive/Intellij?

also, what happened to the IRC channel? It seems that all messages are now blocked. Have the moderators from the irc channel moved to this slack channel?

freenode (the irc network that the channel is on) has been experiencing a pretty bad spam attack, so many channels there are +R meaning you must have a registered nick https://freenode.net/kb/answer/registration

thanks @hiredman

newbie question: I want to process a csv file. I defined the dependency in my project.clj file [clojure-csv/clojure-csv "2.0.1"]

how do I know what I need to require in the repl or in my source.

(require 'clojure-csv/clojure-csv) throws an error.

same for clojure.csv

what's the "canonical" way to find that magical word?

(require '[clojure-csv/clojure-csv :as csv])

Assuming that’s the correct namespace to require

According to the readme looks like you want clojure-csv.core

(there’s no real way to discover that (that I know of) other than looking through the code or in the library’s README; people usually put it right at the top of the README though)

thank you. I found something in <test> directory. I should have looked earlier before asking here.

... in the <test> ...

@gseyffert My understanding is, that I provide the name of the namespace of said module? So I'd look into src/<projectname>/core.clj of said module to find out what's in "(ns ...)"?

hey all, as has been mentioned in various places, the core team is currently working on some improvements around error reporting, etc. I think this is really starting to pay off and I look forward to getting it out into the wild. I have a variety of error examples I am looking at but right now I would be very interested in collecting some more examples that are core macro syntax spec errors (let, if-let, when-let, defn, defn-, fn, ns, import, refer-clojure).
