hello all, is the corret ->

to

?

You may want to use reify instead of proxy since HostKeyVerifier is an interface (sshj, correct?)

you're forgetting your 'this' argument to .addHostKeyVerifier

i.e. ssh in the Java code needs to be the first argument to .addHostKeyVerifier in the Clojure code, I believe

Similarly, your verify method also needs to accept a this parameter first.

(.addHostKeyVerifier
  ssh
  (reify HostKeyVerifier
    (verify [this s i p] true)))

@fellshard, the "this" was from doto 🙂, and yes, interface from sshj, and thank you, it worked

telegraf

doesn't seem like a bug. when reading in cljs tools.reader has no idea that baz is aliased

@ghadi sure, but i'd expect the reader to think like "oh, i'm reading the clj branch of a reader conditional - let's consider those clj aliases I tossed away earlier"

the reader doesn't evaluate things

handling aliases requires ns to be evaluated

@ghadi how does it read any ::foo/bar like keywords then? surely it has to be aware that some namespace was aliased as foo

Oh -- right. You're reading with cljs but the alias hasn't been defined.

Agh. I see what you mean.

@ghadi probably not a bug, but a feature request

which tools.reader again?

@ghadi stacktrace says clojure.tools.reader

hello, i'm trying to get greglook/whidbey working in boot repl, anyone here familiar with that code?

I'm trying to build a core.async channel to cycle thru responses every time the channel is read. But every time I try and read it blocks. Why?

(def c (chan))
 (go (>! c (cycle [:a :b])))
 (<!! c)

Newbee question: If I have this data, how do I go about "searching" for Example 2? In Ruby you could do something like .where(name: "Example2")

[{:name "Example 1"
 :description "This is a description"}
{:name "Example 2"
 :description "This is a description"}
{:name "Example 3"
 :description "This is a description"]

@eoy You would use filter to find the match. (filter #(= “Example 2” (:name %)) [{:name ,,,}])

That will return a seq of all the matches. If you only want the first one, you can call first on the result.

Awesome, thanks!

And if I wanted to grab all that matches a regex of #"Example" I'd just have to modify the condition?

Yes. You’d still use filter, but with a different predicate function.

I'm guessing there is no ~=

No, but there are functions that work on regexes.

Mostly starting with re-

right, like re-matches and re-seq

I'll figure this out 🙂

Yes

One catch to watch out for.

An empty string counts as a “truthy” value

Only nil and false are falsey.

God Clojure is complex to learn coming from a quite purely object oriented background

For sure there’s a learning curve.

@vigilancetech I think the line where you do (go (>! c (cycle [:a :b]))) is doing something different than you expect.

That puts one value into the channel

someone on IRC answered my question.

Which will be the entire contents of the infinite sequence returned from cycle.

I needed to set it up with async/to-chan

@mtnygard actually I was getting 0 values 🙂

@vigilancetech Because it would never finish realizing the value of cycle to put it into the channel, right?

I read somewhere that like cond is lazy and conj is not or vice versa, so I'm thinking perhaps using one of those to get a lazy take infinity might work

Oh, I know what's happening I think. Its trying to give an infinite sequence to the channel because that's probably hungry

anyway, a lot of clojure is still a mystery to me

is there any documentation on the new namespaced maps features in 1.9?

I’d like to know how to remove namespaces from keys in a map

also I’ve been running into this problem in 1.9-alpha14 RuntimeException EOF while reading and then RuntimeException Unmatched delimiter: } :

(def a #:test{:a 1
              :b 1})

this works though

(def b #:test{:a 1 :b 1})

here’s my solution for removing ns from map:

(defn unqualify [m]
  (com.rpl.specter.macros/transform [(com.rpl.specter/walker keyword?)] (comp keyword name) m))

@vigilancetech: neither cond or conj is lazy, lazy-seq is lazy

and maybe you were thinking of cons, not cond

to answer my question above, http://clojure.org/reference/reader under "Map namespace syntax“ has some documentation on the new reader syntax
