Re: [Large File Processing] What am I doing wrong?

[danneu]

I use line-seq, split, and destructuring to parse large CSVs.

Here's how I'd approach what I think you're trying to do:

(with-open [rdr (io/reader (io/resource csv :encoding "UTF-16"))]
(let [extract-url-hash (fn [line]
 (let [[_ _ _ url & _] (str/split line 
#"\t")]
   [(m/md5 url) url]))]
  (->> (drop 1 (line-seq rdr))
   (map extract-url-hash)
   (into {}

Thanks for reporting. This was introduced in 0.5.4, and I've pushed a fixed

Glad to hear it. I recommend taking a look at the new section "Higher Order

we're finally getting to the "good stuff" IMO :)

 Yes your compilation technology could enable a lot of creative thinking
 around frameworks and libraries for iOS UI construction in Clojure. Much
 like the excitement and development in the RubyMotion community. I need to
 put my hard hat on and experiment more.

 Again thanks for the fabulous contribution.

Re: Helping newcomers get involved in Clojure projects

[Timothy Washington]

Hi Marcus,

Thanks for the offer of help. There's no mailing list yet. But I'll
certainly set that up, if need be.

Were you able to clone and start the system? The first thing I want to do
is make it easy to setup. So let me know what else you could use, in
addition to what's in the
Install/Runsection.
I'm currently trying to
*i)* improve starting stefon from a plugin (like the compojure
webui)
and *ii)* have a clean plugin configuration and loading mechanism.

Academy Award goes to a literate program

[daly]

>From http://lambda-the-ultimate.org/node/4876:

Matt Pharr, Greg Humphreys, and Pat Hanrahan have recently been given an
Academy Award for Technical Achievement, for the book Physically Based
Rendering. This is the first time the award has been given to a book and
(more relevant to LtU) the first time a literate program has won an
Academy Award.

Re: Help about using clojure in org mode in Emacs with CIDER

[Matching Socks]

I tried updating org alone, but I evidently caused a mishmash of old and 
new elisp file versions that didn't work.  So I built Emacs from the trunk 
branch (emacs-version 24.3.50.1), and blended Org from the master branch to 
get Cider.  According to package-list-packages, I am using cider 20140125.  

(1) Is it still possible for a Clojure code block to accept an org table as 
an argument?  

#+tblname: columnar-stuff
| State   | Bird  |
| New York| Eastern Bluebird  |
| New Jersey  | Eastern Goldfinch |
| Connecticut | Penguin   |

#+name: read-columnar-s(rows=columnar-stuff)
#+begin_src clojure :exports both :results pp
  (let [headings (first rows)]
(map #(zipmap headings %) (rest rows)))
#+end_src

#+RESULTS: read-columnar-s
: CompilerException java.lang.RuntimeException: Unable to resolve symbol: 
rows in this context, compiling:(NO_SOURCE_PATH:1:165) 

(2) There was a thread last March about emitting nice Org tables from code 
blocks. (https://groups.google.com/d/msg/clojure/71MEGeYiUKA/tf6rYdfvXrwJ)  
Is it still possible to emit a nice Org table from a Clojure code block?  I 
copied from the March example, but the results section does not look right, 
and after M-x org-latex-export-to-latex, LaTeX gets stuck on an "Undefined 
control sequence":

#+begin_src clojure :exports both :results value raw
(with-out-str (print-table [{:a 1 :b 2 :c 3} {:b 5 :a 7 :c "dog"}]))
#+end_src

#+RESULTS:
"\n| :a |  :c | :b |\n|+-+|\n|  1 |   3 |  2 |\n|  7 | dog |  5 
|\n"

(3) I would also like to pretty-print expressions, so the results would fit 
in LaTeX margins.  How can I do that with ob-clojure?  ":results pp" gives 
a result reminiscent of the above flattened table.

#+begin_src clojure :exports both :results pp
(def birds [["State","Bird"]
["New York", "Eastern Bluebird"]
["New Jersey", "Eastern Goldfinch"]
["Connecticut", "Penguin"]])
birds
#+end_src

#+RESULTS:
: "[[\"State\" \"Bird\"]\n [\"New York\" \"Eastern Bluebird\"]\n [\"New 
Jersey\" \"Eastern Goldfinch\"]\n [\"Connecticut\" \"Penguin\"]]\n"

Re: [ANN] com.stuartsierra/frequencies "0.1.0"

[A]

This is so awesome.  Thanks for writing this!  


Here's my naive stab at integration with (the :iris dataset available in) 
Incanter...

 (:require [incanter.core :as i]  
[incanter.datasets :as id]
[com.stuartsierra.frequencies :as freq])

(def d (id/get-dataset :iris)) 

   


(for [k [:Sepal.Length :Sepal.Width :Petal.Length :Petal.Width ] 
]   


  (-> d 


 

  
i/to-map

   

  
k   

   

  
frequencies 

   

  
freq/stats  

   

  (assoc :field k)   ;; label the stats with the field we 
used
   

  ))  


What do people think about Incanter these days?  Is it a forgotten 
step-child of clojure data science dreams or ready for a renaissance?


Cheers,
Avram

Re: core.asyn: missing sequence functions?

[Olaf Delgado-Friedrichs]

I can't speak for the core.async implementers, of course, but I've been 
working on a similar library for Javascript, and had to realised that not 
all sequence operations make sense, or are even possible in the context of 
channels.

The one you mentioned, take-while, is a good example. Once you've taken the 
first item from the channel that does not satisfy the predicate, there is 
no way to put it back without breaking the abstraction. So I think the best 
one could do in order not to lose any data is implement something like a 
'take-until' that produces all elements of the channel up until the first 
one that satisfies a given predicate.

Cheers,
Olaf

Actually looks like Stuart ended up doing a non-SNAPSHOT release of

sure, but it depends on who is going to use your project too. if it's only you,

Sorry, that's just won't fly. It's library maintainer's responsibility to
make
sure the project is reasonably easy to use.

If something is not ready for a release yet, that's fine: simply don't
announce
it until it is.

Re: ANN: clojure-objc

[Gal Dolber]

That's a bug in the objc interop, the type detection is incomplete.

https://github.com/galdolber/clojure-objc/blob/master/src/jvm/clojure/lang/Selector.java?source=c#L87

The error you get is happening on arm64(iphone 5s or simulator 64bits), it
should work on i386, armv7 and armv7s.

Please don't deploy a project to the public clojars repository for

Re: Web App structure on server?

[john walker]

I spent some time yesterday with node webkit and clojurescript. There's not 
really much to it.

There's a :target :nodejs that you can hand off to leiningen, but I don't 
really know what it's for (and no one else seems to either). Make sure that 
when you inspect the resultant javascript source that you see the google 
closure inlined. This means fiddling with compilation settings. From then 
on, you can follow nodejs tutorials.

Re: Web App structure on server?

[Joshua Ballanco]

I don’t have much practical experience with CLJS+Node myself, but the intro on 
the ClojureScript wiki has been helpful with the couple experiments I’ve tried: 
https://github.com/clojure/clojurescript/wiki/Quick-Start . Really, though, it 
comes down to the fact that ClojureScript compiles down to JS, and you can just 
hand those over to Node to be run. Sorry I can’t be of more help…  

Cheers,

Josh

I got an error as posted in my 1:01 PM post below. I've uploaded my source

And if you are not sure about that, just use edn-only reader:

(require '[clojure.tools.reader.edn :as edn])

(edn/read-string (slurp "file"))

If you are sure that the file doesn't contain malicious code you can use:

 At present I am working on an application for a client, and I am trying to

 If I were doing this in another language I would simply write the smaller

 then set the crons.
 
 How do I do this with Clojure? If I package each micro-app as an uberjar 
 that is a lot of JVM, likely eating at the resources of the poor (see: 
 crappy) VPSs this project will likely run on.
 
 Thoughts?
 
 How do you structure web Clojure apps beyond: put the whole thing in a 
 servlet\uberjar?

Issues with the keyword :as aliasing

[Paul Smith]

Hi,

I am requiring clojure.java.io as such

(ns sample-project.core
  (:require [clojure.java.io :as io]))

However, the first expression creates a file object
(clojure.java.io/file "test")
#

The second expression explodes with "java.lang.RuntimeException: No such
namespace: io"
(io/file "/tmp/paul-test")

But as you can see, I have created the alias in my namespace.

Why is this so?

Thanks

Paul

Read file contents as map

[Paul Smith]

Hi,

I have a config file that contains a Clojure map. If I slurp that file it 
obviously returns a string. 

Is it possible to return that read file as a map (its original data 
structure) and not a string?

Thanks

Paul

core.asyn: missing sequence functions?

[Daniel Solano Gómez]

Hello, all,

I have just started using core.async, and I was curious as to why
particular sequence functions where chosen to be implemented.  For
example, there is take, but no take-while or drop.  Is this a deliberate
design decision?

Thanks for the great library!

Sincerely,

Daniel

I added a better sample with a UINavigationController and a small uikit
framework(very very alpha).

https://github.com/galdolber/clojure-objc-sample/blob/master/src/clojure_objc_sample/core.clj

Feedback and improvements on the uikit framework are very much welcome.

Re: [ANN] om-start lein template for nrepl compliant editors/IDEs

[Mimmo Cosenza]

Thanks Rudy!

There is still room for improvements. At the moment I was not able make it to 
run with :none optimisation which is amazingly fast, while :whitespace an all 
the others are slow. But with an nrepl compliant editor/IDE you could enjoy the 
live coding stuff by David without running the lein cljsbuild auto. So, it's 
not a big deal.

But it's my opinion that we should extend that CLJS live experience to a TDD 
workflow too. We're not that faraway. cljsbuild is close to support auto mode 
for the test task, clojurescript.test is almost ready to support asynchronous 
tests.

The only two things that I don't now if they will be quickly solved are:
- the above limitation about using :none with austin browser connected REPL
- the same limitation about using :none with clojurescript.test.

Again, if 7/10 seconds of recompilation time is not considered inadequate for a 
TDD workflow, we can stays with the :whitespace compilation option both for 
austin and clojurescript.test.

Hi Mimmo

Thank you for this tutorial - I managed to follow along and experience the same 
live coding with emacs/cider - really nice to see how all the components work 
together and "drive" the browser from the browser-repl in emacs.

Kind regards

Re: async/close! called when channel is gc-ed ?

[Cedric Greevey]

(b) is easy if you're willing to drop down to Java, or use gen-class. You
can define a finalize method.

On the other hand, you might also want to look into WeakReference and
ReferenceQueue, which can be used from Clojure with interop. You can
discover when objects become eligible for GC with ReferenceQueue, if they
are held by WeakReference (or SoftReference). So you could create a
channel, a ReferenceQueue, a WeakReference on the channel set up to use
that ReferenceQueue, and a map with mappings from WeakReference to some
sort of identifiers, as well as mappings from identifiers to functions to
call. When a reference shows up on the queue the mapping is used to look up
the id and then the function and invoke it. The modified channel can
directly call the same function when closed. The function can take the id
as a parameter and use a map in the other direction, from id to
WeakReference, to remove all of the mappings for a given id when called
with that id, before doing whatever else it does. It won't have access to
the channel object, at least not if that's been GC'd, but it wouldn't be
able to do much with it anyway in the case where the channel was closed,
save use the channel as a lookup key itself, and the id can serve that
purpose.

Re: core.async over websocket + cljs + clojure

Hi folks, sorry I'm a bit late to the party, but Chord might be a good base for 
what you want to do? It probably falls a bit short at the moment on your 
disconnection semantics, but could be worth a shot.

async/close! called when channel is gc-ed ?

[t x]

## Context:

  I'm doing some communication across cljs/clj with core.async

## Problem:

  I want a certain function called whenever:
  (a) the first time the channel is closed
  (b) when the channel is gc-ed (if not previously closed)

  (a) is rather easy: I define my own channel, wrapped around
ManyToManyChannel, and define my own
https://github.com/clojure/core.async/blob/master/src/main/clojure/clojure/core/async/impl/protocols.clj#L22

  (b) I have no idea how to do -- is there someway to register some
function that gets called when a channel is gc-ed ? (perferably in both
cljs + clj -- although, if it just works in cljs, it suffices)

Thanks!

   (vector? obj) (apply vector (map filter-printable obj))

Re: clojure.edn/read-string exceptions => nil

[t x]

I recently ran into this problem again.

The solution I came up with is:

(defn filter-printable [obj]
  (cond
   (or (symbol? obj) (number? obj) (string? obj) (keyword? obj)) obj
   (vector? obj) (apply vector (map filter-printable obj))
   (seq? obj) (map filter-printable obj)
   (set? obj) (into #{} (map filter-printable obj))
   (map? obj) (into {} (for [[k v] obj]
 [(filter-printable v) (filter-printable v)]))
   true [:un-readable (pr-str obj)]))

## example:

(filter-printable
 {:k 20
  :f 'abc
  :d '(+ 1 2 3 foo)
  :other (async/chan 10)})


Anyone have a better / more elegant solution?
