Re: [ANN] electron-app 1.0.0

[Johannes]

Hi,
today I followed the usage instructions. Trying to run a development build 
with clojure -A:dev I get the windows "myapp" and "myapp Tests" but both 
are empty.
The repl is started and (conns) delivers

Will Eval On: Judson
Session Name Age URL
Judson 0m /figwheel-connect
nil

Are there any hints, what I should do. I am working on macOs.

Re: Conceptual difference between map and class

[Johannes]

A few years ago I built some kind of internal DSL using Clojure macros 
which allowed to create objects and classes like in conventional OOP 
languages as Smalltalk and Java.

The macro obj creates a classless, immutable object, for example:
(obj {:x 1, :y 2} {:f (fn [] (+ (self :x) (self :y)))})
obj expects to maps as arguments, one for the instance variables (:x and 
:y) and one for the methods (:f). The variable self is provided by obj
 automatically.
The methods can be activated using a message passing style:
((obj {:x 1, :y 2} {:f (fn [] (+ (self :x) (self :y)))}) :f) ;=>3
Classes can be created through an explicit abstraction step by sending the 
message :kappa to an object:
((obj {:x 1, :y 2} {:f (fn [] (+ (self :x) (self :y)))}) :kappa 'C) ;=> 
#'dosl2clj.core/C
Classes understand the message :new  for creating new instances:
((C :new) :data) ;=> {:x 1, :y 2}
All objects understand the message :data. Class hierarchies are possible, 
too.

I built the DSL, because I wanted to figure out, wether it could make 
porting an application from Smalltalk to Clojure less difficult. I tried 
two simple applications.
My conclusion is: Yes, the porting is possible, of course, and quite 
simple. But it is in no way simpler than using the native Clojure language 
features. Using normal hash-maps and functions isn't more difficult. 
Building a DSL for objects isn't worth the effort.

Thank you for the explanation; until now I associated this behavior only to

I fear I was wrong. The connection to the cider-repl wasn't okay.

Now I get the same (wrong) answer as before:
 
#+BEGIN_SRC clojure :results value
(* 3 5)
#+END_SRC

#+RESULTS:
: nil15

Re: questionable result of Clojure code execution in org babel

[Johannes]

Until today there is no response to my post on org mode list.

In the meantime I've upgraded Aquamacs to the lastest stable version (3.5) 
and upgraded all my packages (esp. Org mode version 9.2.6).
If I now try to execute the the following code section in an org-mode file 
with C-c C-c

#+BEGIN_SRC clojure :results value
(* 3 5)
#+END_SRC

I get the error message:
executing Clojure code block...
nrepl-send-sync-request: Wrong type argument: stringp, nil

There is a running cider-real.

The former behavior wasn't nice but better than this.

Any ideas what to do?

questionable result of Clojure code execution in org babel

[Johannes]

Hi

executing the the following code section in an org-mode file with C-c C-c

#+BEGIN_SRC clojure :results value
(* 3 5)
#+END_SRC

I get 

 #+RESULTS:
 : nil15

instead of

 #+RESULTS:
 : 15

Trying the same with emacs-lisp instead of clojure the correct result 
appears.

What is going wrong?

Re: downloading of files from Dropbox using cli-http

[Johannes]

Yes, there was an authorisation problem, I have to include :with-credentials? 
false. Additionally the "Content-Type" has to be specified in the headers. 
The following call works now:
(go (let [response (https://content.dropboxapi.com/2/files/download";
  {:with-credentials? false
   :headers {"authorization" "Bearer 
QfCC..."
 "Dropbox-API-Arg" 
"{\"path\":\"/log.txt\"}"
 "Content-Type" "text/plain; 
charset=utf-8"}     
   }))] 
  (println response)))

Thanks for your help!

Re: downloading of files from Dropbox using cli-http

[Johannes]

Thanks Immo, what a silly mistake!

But after having corrected it, I get the same result as before:

(go (let [response (https://content.dropboxapi.com/2/files/download";
  {:headers {"authorization" "Bearer 
QfCCK..."
 "Dropbox-API-Arg" 
"{\"path\":\"/log.txt\"}"} 
   }))] 
  (println response)))

==>

#object[*cljs.core.async.impl.channels.ManyToManyChannel*]

{:status 0, :success false, :body , :headers {}, :trace-redirects

downloading of files from Dropbox using cli-http

[Johannes]

Hi,

I am trying to download a file from Dropbox which I can get with the Http 
request:

POST /2/files/download Host: https://content.dropboxapi.com User-Agent: 
api-explorer-client Authorization: Bearer QfCCK... Dropbox-API-Arg: 
{"path":"/log.txt"}

or the curl request looks like that:

curl -X POST https://content.dropboxapi.com/2/files/download \ --header 
'Authorization: 
Bearer QfCCK...' \ --header 'Dropbox-API-Arg: {"path":"/log.txt"}'

If I try the following using cli-http in a Clojurescript repl:

(go (let [response (https://content/dropboxapi.com/2/files/download"; {:headers 
{"authorization" "Bearer QfCCK..." "Dropbox-API-Arg" 
"{\"path\":\"/log.txt\"}"} }))] (println response)))

I get

#object[*cljs.core.async.impl.channels.ManyToManyChannel*]

{:status 0, :success false, :body , :headers {}, :trace-redirects 
[https://content/dropboxapi.com/2/files/download 
https://content/dropboxapi.com/2/files/download], :error-code :http-error, 
:error-text  [0]}


I cannot figure out where my mistake is. Any help?

Re: Application silently shuts down by itself after running for some hours

[Johannes Ahvenniemi]

I'm under the impression that setDefaultExceptionHandler still catches OOM 
errors. Some googling suggests this too. If not, how should I try to catch it?

I am running the app on a virtual server with 512mb ram. free -m is showing 
30mb free. Lack of memory can be the issue. What would be the best way to 
confirm this if I'm not able to log the error?

results of expression evaluation using clojure in org mode in Emacs with CIDER

[Johannes]

Hi,

without problems I can do something like that:

#+begin_src clojure :results value
  (get [ 1 2 3 4] 3)
#+end_src

#+RESULTS:
: 4

But evaluating 
#+begin_src clojure :results value
  [ 1 2 3 4]
#+end_src
I get
#+RESULTS:
| 1 | 2 | 3 | 4 |
instead of 
[1 2 3 4]

My org-mode version: Org-mode version 8.3.6 (8.3.6-7-g4d7d52-elpa @ 
/Users/johannes/Library/Preferences/Aquamacs 
Emacs/Packages/elpa/org-20161010/)

Any hints?

I think, I understand, but nevertheless I cannot understand why
{:f `(~(let [v (fn [] 1)
   f (fn [x] (v))] f))} 
evaluates as expected, but
(eval {:f `(~(let [v (fn [] 1)
   f (fn [x] (v))] f))})
does not. That looks like a bug, for me.

The problem is that the place in my program where I give the map containing

strange (for me) problem with "No matching ctor found for class ..."

[Johannes]

Hi!

I have a function f- defined using a local function f which uses a local 
var v:
user> (def f- (let [v 1
  f (fn [x] v)] f))
;; => #'user/f-

Putting f- in a map
user> {:d f-}
;; => {:d #function[user/fn--13335/f--13336]}
all is as expected. But giving the map as argument to eval
user> (eval {:d f-})
this error message appear:
IllegalArgumentException No matching ctor found for class 
user$fn__13335$f__13336  clojure.lang.Reflector.invokeConstructor 
(Reflector.java:163)

This problem doesn't arise if the local function f doesn't  use v:
user> (def f- (let [v 1
  f (fn [x] x)] f))
;; => #'user/f-
user> (eval {:d f-})
;; => {:d #function[user/fn--13345/f--13346]}

Is there any explanation for this behavior?

 If it all seems confusing, do not despair, there's two things that will 
 handle the vast majority of the use cases you may have: 

 1) `future` - spawns a thread that runs the body of the future (
 https://clojuredocs.org/clojure.core/future)
 2) `atom` and `swap!` - Used to store data that needs to be shared 
 between threads and updated concurrently (
 https://clojuredocs.org/clojure.core/atom) these are built on top of 
 CAS, which itself is foundation upon which most of concurrent programming 
 is built. (https://en.wikipedia.org/wiki/Compare-and-swap)

 Those two primitives alone will handle 90% of the use cases you will 
 run into as a new clojure developer. The rest of the stuff (agents, thread 
 pools, refs, vars, cps/core.async) can all come in time, but you will use 
 them much less often than threads and atoms. So read up on those two and 
 feel free to come back with any questions you may have.

Re: org-mode Clojure babel

[Johannes Brauer]

Hi!

Thank you for your hints.

...
One thing to do is look at your Org mode's ob-clojure.el and figure out whether 
it mentions cider.  (The older or "stable" versions use only slime or nrepl.)  
The Org website is a house of mirrors, but somewhere you should find a tidy 
tar.gz of a nicely assembled Org whose ob-clojure.el covers cider.
indeed, my version of ob-clojure did not mention cider. I’ve one in the house 
of mirrors (http://orgmode.org/cgit.cgi/org-mode.git/plain/lisp/ob-clojure.el) 
which does.
But the error message
 executing Clojure code block...
 let: Wrong number of arguments: (3 . 4), 1
remains.

Another thing that might go wrong, is that the cider-capable version of 
ob-clojure may try to detect whether it should use cider, nrepl, or slime.  
Detection might reach an unfortunate conclusion if Emacs had not loaded cider.  
Therefore, it might help to open a cider REPL buffer before opening any Org 
buffers.  (If I recall, Org Babel will need that REPL sooner or later anyway; 
it does not open its own REPL.)
I tried this too, but without success

Re: org-mode Clojure babel

[Johannes Brauer]

Hi Stuart,

thanks a lot for your help. I’ve included your settings in my Emacs (Aquamacs) 
setup. After having activated CIDER I tried to compile (C-c C-c) a little code 
snippet:

#+begin_src clojure  :results silent
   (+ 1 2)
#+end_src

What happens, is:

Evaluate this clojure code block on your system? (y or n) y
executing Clojure code block...
let: Wrong number of arguments: (3 . 4), 1

What I am doing wrongly?

I am looking for a working environment for using org-mode with Clojure

Hi, I can't figure this out.  I have these two functions:

(defn get-number []
  (try (let [input (read-string (read-line))]
 (if (number? input)
   input
   (get-number)))
   (catch Exception e (get-number

(defn selection-handler [tests]
  (dotimes [i (count tests)]
(printf "(%s) %s: %s\n"
(inc i)
(first (nth tests i))
(or (second (nth tests i))
"--")))
  (loop [input (dec (get-number))]
(if ((set (range (count tests))) input)
  (nth tests input)
  (recur (dec (get-number))

Now, the problem is that when I run selection-handler, the dotimes output 
isn't printed until (get-number) has returned. Why is this?

Re: cannot import namespace reducers

[Johannes Brauer]

if I remember correctly I solved the problem by reinstalling Java 7 from 
Oracle. Thereafter my $JAVA_HOME points to:
/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home

I am trying to build an alternative record building macro. For example

(define-record point [x y])
should define 
- a new type point
- a constructor make-point
- a type checker point?
- and 2 getters point-x and point-y

both, I am learning about macros and I enjoy to build an alternative syntax 
for records; I know that the keywords can be uses as accessors

question concerning macros by a newbie

[Johannes]

Hi,

I define a record
(defrecord point [x y])

and the following macro:

(defmacro drg
  [typename components]
  `(def ~(symbol (str typename "-" (str (first components
 (fn [~(symbol "obj")] (get ~(symbol "obj") ~(symbol (str ":" (str 
(first components

the call 
user> (macroexpand-1 '(drg point [x y]))

delivers what I expect:
(def point-x (clojure.core/fn [obj] (clojure.core/get obj :x)))

Evalutating this expression at the repl delivers what I expect:
user> (def point-x (clojure.core/fn [obj] (clojure.core/get obj :x)))
#'user/point-x

But calling the macro results in an error message:
user> (drg point [x y])
CompilerException java.lang.RuntimeException: Unable to resolve symbol: :x 
in this context, compiling:(NO_SOURCE_PATH:1) 

Can anyone tell me what my mistake is?

Johannes
