Re: Can I use reduce here?
Hi Robin, thanks for the example of reduce above! That was what I was looking for. I will try it out once I'm at my desk again. / Mathias -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Can I use reduce here?
Hi all,
a short question from a newbie. I have a data structure like:
"mytitle1"; "2015-02-01"
"mytitle2"; "2015-03-12"
"";2015-03-28"
"mytitle3; "2015-01-12"
and want something like this
[{:title "mytitle1" :events [{:date "2015-02-01}]}
{:title "mytitle2" :events [{:date "2015-03-12"} {:date "2015-03-28"}]}
{:title "mytitle3" :events [{:date "2015-01-12"}]}]
I can recurse through the csv manually, but I have a dim feeling this might
be a job for reduce, but can't wrap my head around it...
Can anyone give me a hint if and how this could be done? Or just tell me
that I'm mistaken?
If I'm wrong about reduce, anything which uses part of the standard lib to
make this a more elegant solution would be interesting.
Thanks,
Mathias

clj-pdf: how to serve a pdf with ring
I'm trying to serve a clj-http generated document directly via
ring/compojure.
I thought ring.util/piped-output-stream would work, but it seems I'm not
understanding something here...
This:
(defn laminat-pdf-t
[natno]
(piped-input-stream
(fn [output-stream])
(pdf
[ {:title (str "Omanimali-Kuscheltierpass" natno)
:orientation :landscape
:size :a6
:author "Omanimali - Stefanie Tuschen"
:register-system-fonts true
}
;; [:svg {} (clojure.java.io/file
;; (str "/einbuergern/" natno "/svg" ))]
[:paragraph "Some Text"] ]
output-stream)))
(defn laminat-pdf
"generate individualized cuddly toy passport page"
[natno]
{:headers {"Content-Type" "application/pdf"}
:body (laminat-pdf-t natno)})
leads to an empty response...
What do I need to do differently?
Thanks,
Mathias

Re: core.async and performance
Did you look into Pulsar https://github.com/puniverse/pulsar ? I'm using core.async in the browser, but I don't see it as a multithreading mechanism. Pulsar puts an erlang-like api around the quasar lightweight threads and actors for java. Looks really nice, and seems a good fit for dse type apps, but I haven't used it yet, just have it on my todo list to check out. Look here https://groups.google.com/forum/#!msg/clojure/1xxxTti6Vi0/VjIngrSnG8MJ for an interesting performance comparison for a core.async implemented on top of pulsar, which might give you some hints how both projects might fare for your use case.

Re: binding and core.async? (trying to use shoreleave-remote in go block)
I allready go some help on IRC, define a function with the binding and rpc
call inside it and then calling that function in my go block works.
I'm now trying to test a simple code snippet Anderkent gave me to see is
this is a bug, but that will have to wait till tomorrow or so...

binding and core.async? (trying to use shoreleave-remote in go block)
Hi all,
I'm fighting with shoreleave-remote-ring running on a non default context
(immutant), and me not being able to rebind
shoreleave.remotes.http-rpc/*remote-uri* inside a go block.
If you look at https://gist.github.com/mathiasp/6448753, you will find a
code snippet in the init function which works as expected:
(binding [srh/*remote-uri* "/opnenablement/_shoreleave"]
;;; this works as expected, goes to /opnenablement/_shoreleave
(srm/rpc (save-config "myConfig") [result]
:on-success (js/alert (str "Success: " result))
:on-error (js/alert (str "Error: " result
but the same code does not work inside the go block.
Binding anything inside the go block gives me an error ("nth not supported
on this type: Symbol"), and putting the binding anywhere outside it does
not have any effect, the rpc call goes to /_shoreleave, ignoring the
binding of *remote-uri* to /opnenablement/_shoreleave. If I look in the
compiled javascript, the binding seems to get redefined just fine...???
I'm banging my head on the for two hours allready, maybe you can give me
some help.
I'm new to clojure and core.async, so maybe, hopefully, I'm missing
something obvious?
Thanks, Mathias
