Re: [ANN] ClojureScript release 0.0-1535 with G.Closure 0.0-2029

[Herwig Hochleitner]

I've seen this same NPE in my project. I managed to work around it by
temporarily throwing out the browser repl. It seems to trigger the NPE. Not
sure how and why.

Re: [ClojureScript] Single Output File for Multiple Pages or Multiple Output Files?

[Mimmo Cosenza]

Hi Zhao,
sorry to be so late, but I did not see your question until now. I was 
investigating a similar issue in writing a short series of clojurescript 
tutorials (https://github.com/magomimmo/modern-cljs). 

The problem of sharing in more pages the same js emitted by the 
clojurescript/closure compilers could be solved, in my case, just removing 
from the cljs code any js/window setting of properties (i.e. onload) and 
putting that (e.g (set! (.-onload js/windows) init)  call directly in a 
script tag in the corresponding  html pages as:

modern_cljs.login.init();

and 

modern_cljs.shopping.init():

If you take a look to the last published tutorial (i.e. tutorial 5) in 
https://github.com/magomimmo/modern-cljs 
you can find the context I'm talking about. 

HIH

Mimmo

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?

Re: question concerning macros by a newbie

[Christophe Grand]

(symbol (str ":" (str (first components should be (keyword (first
components))
In your expansion, :x is not a keyword but a symbol starting by a colon --
the symbol fn performs no validation on its input.
When you copied/pasted it for evaluation it was then read as a keyword.

Btw I'm a little worried: are you planning to generate accessors for your
fields or are you just toying with macros?

hth,

Christophe

Re: question concerning macros by a newbie

[Jim foo.bar]

You can't convert to keyword simply by (str ":" (str (first 
components))...you need the (keyword (first components))...also why is 
your argument (symbol "obj")? I'd prefer obj# or (gensym obj)...

I guess the problem is that you created :x using symbol, so it is not 
recognized as a key.


But the whole approach, starting with creating names to def to inside a 
macro, is troublesome. This makes it hard to follow what's going on. If 
you provide a larger context of what you are trying to accomplish, I'm 
sure someone can suggest a much better approach.

Here's how you wrap your application with middleware (root-routes is your
main routes:

(def app
  (-> #'root-routes
   (friend/authenticate …)
   (wrap-keyword-params)
   (wrap-params)
   …))

Now following your example you can
(web/start app)

note that the above set of middleware are just sample. I have no idea if
this is all you need. If you'll use the hiccup library you have a
'handler/site' function that includes many of the required middleware you
need for a website (you can also just check the documentation to see the
list of middleware it uses).

In order to learn more about middleware check the *middleware* section here:
https://github.com/ring-clojure/ring/wiki/Concepts

Also, the friend repository has a mock application you can check:
https://github.com/cemerick/friend/blob/master/test/test_friend/mock_app.clj

Re: [ANN] ClojureScript release 0.0-1535 with G.Closure 0.0-2029

[Herwig Hochleitner]

I've debugged a bit, the underlying cause seems to be that
goog.net.xpc.CrosspageChannel uses goog.async.Deferred, which lives in
third_party.
In my project, I could indeed successfully compile again with the browser
repl, by adding the third-party jar.

This leaves two open issues:

Why the NPE in cljsbuild?
script/cljsc complains about goog.async.Deferred never provided, as it
should. When compiling with cljsbuild, however, the js-sources list
contains an entry which :provides goog.async.Deferred but has an :uri of
nil, which triggers the breakage when mapping javascript-name over it. I
didn't find out where that entry comes from. This is probably a cljsbuild
issue, so I'll amend the ticket if I have time to look into this within a
few days.

So clojure.browser.repl transitively depends on third_party now
Not only that, there are a lot of files in closure lib proper that depend
on goog.async.Deferred, as you can verify by running

grep -r "goog.require('goog.async.Deferred')" closure/library/closure

from cljs root dir. That begs two questions:
- Are there other third-party libs referred to from closure proper and has
that been the case with older versions?
- Does it still make sense to split closure lib?

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

Re: [ANN] ClojureScript release 0.0-1535 with G.Closure 0.0-2029

[Stuart Sierra]

My original reason for splitting the third-party JAR was the licensing: the 
main G.Closure library is under the Apache license; the third-party 
libraries are under a variety of different licenses.

One simple solution would be to make ClojureScript itself have a dependency 
on the third-party libs in addition to the core G.Closure libraries. Then 
users would still have the option of excluding the third-party extensions 
from their projects.

Re: Interactive form workflow with Friend, can't log in

Thank you! I had something similar already, but my testing got thwarted 
by expecting too much of ring-reload. Now the following does the trick:


(def secured-app

  (friend/authenticate {:credential-fn (partial 
creds/bcrypt-credential-fn users)

:workflows [(workflows/interactive-form)]})
  wrap-keyword-params

(web/start secured-app :reload true)

As a shorthand for (instance? Point my-obj)?  Well, that could make
sense here and there, although in general, if you use those type-checks
like

 (cond
  (Point? o)   (transform-point o)
  (Polygon? o) (transform-polygon o)
  ...)

it's likely that you want a protocol Transformable declaring a
`transform` method, and both Point and Polygon provide an implementation
for it.  Then the above becomes just (transform o), and it'll do the
right thing no matter if it's a Point or Polygon.

> - and 2 getters point-x and point-y

I don't see a benefit of (point-x point) over (:x point).

The main problem with your `define-point` macro is that it should also
allow for defining protocol implementations like `defrecord`.  Else,
it's simply not as powerful as the latter.

Bye,
Tassilo

Re: [ANN] ClojureScript release 0.0-1535 with G.Closure 0.0-2029

[Herwig Hochleitner]

I concur, but maybe we could make a second release of the closure lib main
jar, with a dependency on third-party?
That would reflect the actual dependency.

I know, you asked for testing before the release. Sorry for not catching
this one.

Re: Where did the idea of metadata come from?

[Paul deGrandis]

Here's one use case:

Let's say you want to develop a library that monitors system behavior and 
resources while functions are executed (or while collections are processed).
You might have a collection of monitoring functions (we'll call them 
sensors) that check various things, like disk I/O activity.

We now need a way to annotate our other functions and collections (maps, 
vectors, etc) with the sensors that concern them.
For example, maybe we want to ensure a given function doesn't run off with 
exponential disk writing (commonly called a 'log explosion') - this defect 
caused one of the Mars Rovers to crash.

One way is to attach the sensors directly to the functions in the form of 
metadata.  You could then run the functions in a special context that 
executed sensors from any piece of metadata.
- - - 

Another example might be that you want to attached additional specification 
information to functions, so you can run some sort of analysis/verification 
against your code
- - -

It's difficult to spot the best time to apply metadata, since we've become 
accustomed to working in languages without support for it.
Anytime you want to convey programmatic meaning about entities themselves, 
metadata is an elegant solution.

I hope this helps a little.

Re: First foray into clojure - questions for new project

[David Powell]

cemerick made a screencast of how to get started with Clojure, which
takes you through getting started with the tools, and making a web
app.  It is probably a great place to start:

  http://cemerick.com/2012/05/02/starting-clojure/


For details on the Clojure web stack, I really like this guide:

  http://brehaut.net/blog/2011/ring_introduction


Note that on Clojure the web stack is made up of a bunch of small
libraries.  They are almost all based on ring.  The guide above
describes the common choices.

Yes, but my understanding is that most folks have already upgraded (or have 
plans to upgrade --- thus the upgrading guide) to lein 2.

I suggest using the latest preview release of lein 2 (which is also what's 
recommended at leiningen.org).

Noir is built on top of Compojure. I guess just use what you like better.

I don't think you will use Ring directly initially. So get familiar with it
as you need to, the API is tiny.

Noir is higher level than Compojure, and usually easier for new people
to jump into, but not always as flexible, functional or composable.

It was helpful for me to start from the ground up: Got familiar with ring,

prepared me better for managing the more comprehensive frameworks when it

Macros. Metadata is a perfect way to annotate symbols that need to be
processed in some specific way or to provide extra information when
debugging. Many serious macros I've written use metadata on forms & symbols.

Dynamically building SQL queries with core.match & dynamic variables

[David Jagoe]

G'day all,

I am building a reporting interface on top of a database with a star
schema. The star schema makes it very easy to restrict queries by various
combinations of dimension. Some combinations are legal; others are not.
Hence core.match. The number of possible combinations is large, and I would
like to provide a simple API for setting up the dimensional constraints
before running a query.

I have in mind to use dynamic variables because in generating reports, a
few separate queries to the database are required - always with the same
dimensional constraints for a particular instance of a report. It is a pain
to pass a large number of parameters down the call stack - all the way from
the interface to the presentation layer, to the mapping layer which
ultimately builds and runs the query against the db. It would be even more
of a pain to update all calls with new parameters every time I add a new
dimension to the database.

So the interface would look something like this:

(binding [*dimension1* ... *dimension2* ... *dimension3* ...]
(get-fact-1-aggregates mandatory-dimension-restriction)
(get-fact-2-aggs mandatory-dim-rest)
)

Or more concretely if you like a bit of context:

(binding [*drill-name* "DR1" *hole-name* "h1" *from* timestamp *to*
timestamp2]
(do-something-with (drilling-aggregates 123))
(do-something-with (reaming-aggregates 123))
)

Where 123 would be a company ID set by the user's login credentials and
since it is mandatory and will always be passed I have put it as a formal
parameters.

Here is a rough draft of the code I have in mind.

I would very much appreciate any comments as to the sanity of this
approach, and any other ideas on how to do it better.

Specifically - any better ways of building the query??

Note: I have not populated all the legal combinations of variables so the
match would grow.

Thanks!
David

ANN concerto 0.1.0-SNAPSHOT

[Jamie Brandon]

Concerto extends nrepl (and nrepl.el) with a broadcast mechanism so
that multiple users can colloborate within a single repl.

Just an experiment, I'm curious to see whether anyone has a use for
this. My eventual goal is to use it for collaborative ovetone sessions
but for now I have to get back to other work.

Re: Where did the idea of metadata come from?

[Mimmo Cosenza]

I would to the list the :export metadata used in ClojureScript to prevent 
Google Closure Compiler from minifying variable and function names which 
need to be exposed to regular JS code.

Thanks Laurent,
you're right about CLJS, it's a journey, a good one to me. I'm not a

code waiting on something - cannot debug - driving me insane!!!

[Jim - FooBar();]

Hi all,

I've had this unbelievable problem for some time now but I'm sick and 
tired of ignoring it! It is literally driving nuts...Due to the nature 
of the problem my terminal hangs and Eclipse crashes altogether 
(potentially losing work)!


So what is the problem...Well I really don't have a clue! it is pretty 
obvious that my code is waiting on something but it only happens when 
I've got a dependency on a namespace of mine which uses seesaw. It is 
basically my gui...the bad behaviour is exhibited every time I try to 
reload my namespace after having opened a JFrame regardless of having 
done anything on the frame! I mean the same happens if I open it and 
close it straight after!


anyway, I managed to mock the behaviour with a minimal example:
-

(ns Clondie24.games.dummy
  (:require [Clondie24.lib.gui :as gui]))

(def details {:name 'Dummy
  :players 2
  :arena-size [420 :by 505]
  :tile-size 133})

(defn -main
"Starts a graphical (swing) Chess game."
[& args]
(gui/show-gui! details))


(ns Clondie24.lib.gui
(:require [Clondie24.lib.util :as ut]
  [Clondie24.lib.core :as core]
  [seesaw.core :as ssw]
  [seesaw.chooser :as choo])
(:import  [java.awt AlphaComposite Graphics Graphics2D Toolkit]
  [java.awt.event MouseEvent]
  [javax.swing SwingWorker UIManager]) )

(def curr-game (promise))
(def status-label (ssw/label :id :status :text "Ready!"))

(defn draw-tiles [d ^Graphics g]
  (let [w (ssw/width d)
h (ssw/height d)
tile-size (:tile-size @curr-game)
tiles (map vector (for [x (range 0 w tile-size)
y (range 0 h tile-size)] [x y])
  (cycle (:alternating-colours @curr-game)))]
(when (:alternating-colours @curr-game)
  (doseq [[[x y] c] tiles]
   (.setColor g c)
   (.fillRect g x y tile-size tile-size)) )
 (draw-grid d g)
 (draw-images g)
 (highlight-rects g)))

(def canvas "The paintable canvas - our board"
 (ssw/canvas
:paint draw-tiles
:id :canvas
:listen [:mouse-clicked (fn [e] (when-not (and (:block? @knobs)
 (realized? 
curr-game))

  (canva-react e)))]
))

(defn arena "Constructs and returns the entire arena frame." []
 (ssw/frame
:title "Clondie24 Arena"
:size  (:arena-size @curr-game)
:resizable? false
:on-close :exit
:menubar  nil ;(make-menubar)
:content  (ssw/border-panel
   :border 10
   :hgap 10
   :vgap 10 ;;IGNORE ALL THIS FOLLOWING CODE TO SAVE TIME
   :north  (ssw/horizontal-panel :items
   [(ssw/button :text "Undo"  :listen [:action (fn 
[e] (when-not (:block? @knobs)

(do (refresh :highlighting? false
:hint nil)
(undo!) (ssw/repaint! canvas]) [:fill-h 10]
(ssw/button :text "Clear" :listen [:action (fn 
[e] (when-not (:block? @knobs)

(do (refresh :highlighting? false
:hint nil)
(clear!) (ssw/repaint! canvas]) [:fill-h 10]
(ssw/button :text "Available Moves" :listen 
[:action (fn [e] (when-not (:block? @knobs)
(do 
(refresh :highlighting? true

:hint nil)
(ssw/repaint! canvas]) [:fill-h 10]
(ssw/button :text "Hint" :listen [:action (fn 
[e] (when-not (:block? @knobs)
 (do (knob! 
:highlighting? false)

(with-busy-cursor canvas
  (hint 
(:pref-depth @curr-game)) :hint]) [:fill-h 10]])

   :center canvas
   :south  status-label)))


(defn show-gui! "Everything starts from here." [game-map]
  (deliver curr-game game-map) ;firstly make the gui aware of what game 
we want it to display

   (ssw/invoke-later
 (doto (arena) ssw/show!)))

---

any thoughts / feedback are greatly welcome. I cannot see why such a 
standard setup would hang after trying to reload the dummy namespace. 
everything reloads just fine as long as i don't show anything on 
screen...scary stuff!


thanks in advance...

Jim

[Dave Ray]

Just a wild guess, but if something's shown on the screen,
#'draw-tiles will probably get invoked to paint the canvas and it
might end up blocking on the #'curr-game promise.

Bravo.  I suspect there's lots of fertile ground for supporting alternative 
topologies using custom middlewares and transports.  Carry on. :-)

Re: code waiting on something - cannot debug - driving me insane!!!

[Laurent PETIT]

Hello,

As of the freeze of Eclipse: you're probably using 0.10.1. A problem
of hangs in relation with the way Counterclockwise was talking to the
repl has been fixed in the beta. You could either switch right now to
the beta "channel" ( http://ccw.crand.net/updatesite-betas/ ) either
wait until Thursday, I'll deliver what is currently in beta into a new
stable release (0.10.2)

Sent from a smartphone, please excuse the brevity/typos.

thanks for your response Dave,

even though I'm not entirely sure what you mean, I can confirm that the 
promise is not to blame...I replaced it with an atom and the same thing 
happened...Delivering the promise is the very 1st thing happening so I 
can't see how it might be blocking...also, the canvas does not react 
unless the promise has been realized. After closing the gui I can't do 
anything on the dummy namespace...it hangs indefinately...


any other thoughts? I am quite desperate here...

Jim

ps: thanks Laurent, I'll check out the stable release on Thursday. The 
problem is that I'm not getting any exceptions so I'm not sure to much 
extent  the eclipse debugger can help me.

Dump the JVM's threads [1] and see what it's stuck on?

What am I looking for? I don't see anything related with my project...IT 
is pretty obvious from the output though that everything is waiting! No 
clue what though...

Re: code waiting on something - cannot debug - driving me insane!!!

[Laurent PETIT]

Could you create a small lein2 project on github with what you
previously pasted in this thread correctly spread over files, etc., so
that it's really quick to reproduce the error?

Thanks,

Laurent

ANN: Spyscope 0.1.2

[David Greenberg]

Spyscope is a library that allows you to write very little code to get
threadsafe tracing of your Clojure.

Example: (println #spy/d (+ 1 2 3)) traces the execution of the form '(+ 1
2 3)

Spyscope also supports interactive querying of trace results with a repl
toolkit (see README)

This version of spyscope has a few new features:
- Spyscope now handles mutable objects correctly!
- The README includes directions on enabling Spyscope in every project with
some Leiningen profile settings.
- Herwig Hochleitner has become the first contributor :)


To use, just include [spyscope "0.1.2"] in your project.clj (or follow the
directions in the README to enable globally). You'll need to (require
'spyscope.core) somewhere if you don't add it as an injection.

See https://github.com/dgrnbrg/spyscope for details. Pull requests welcome!

Re: code waiting on something - cannot debug - driving me insane!!!

[Jim - FooBar();]

The original project is already on github...I just committed the dummy 
namespace as well so you can have a look...

so, do:

git clone https://github.com/jimpil/Clondie24.git
cd Clondie24
lein2 repl

(load-file "Clondie24.games.dummy.clj")
(ns Clondie24.games.dummy)
(-main)

then close the frame without doing anything and try evaluating anything 
(e.g "(:name details)").
it goes without saying that the same thing happens in all other proper 
games as well...


thanks a million for looking into this :-)

Jim

lein 2.x not working on Mac OS X 10.7.5 -- Exception in thread "main" java.lang.ClassNotFoundException:

[Alec Ramsay]

When I do "lein run" now, I get "Exception in thread "main" 
java.lang.ClassNotFoundException:".

I'm early in the process of getting a Clojure development environment set 
up--I coded a lot of LISP years ago and want to dust off my skills with 
Clojure--and I have previously successfully done the following on Mac OS X 
10.7.5:

   - Installed Leiningen using Brew--this installed a V1 version
   - Created and run projects ("lein new"; "lein run"; etc.)
   - Everything worked great

However, I wanted to use nREPL in Aquamacs, so I needed lein 2.x. The only 
way I could get lein2 installed was using these 
steps. 
After completing them, I successfully tested nREPL inside Aquamacs. Again 
things seemed to work great.

But while "lein new" still works, "lein run" does not. I get the following 
exception:

Re: lein 2.x not working on Mac OS X 10.7.5 -- Exception in thread "main" java.lang.ClassNotFoundException:

[Marek Šrank]

I also had the same issue some time ago and it was caused by incorrect 
using of dash ('-') vs. underscore ('_') in project/namespace name... I 
don't remember what concretely was wrong, but you at least can try all 
possibilities

Also, are you using gen-class ?

Marek.

Re: Change var in other namespace

this reply was god sent to me. I use tomcat and war to deploy my clojure

That might well be it. An underscore in the file name should always
correspond to a dash in the namespace name.

Re: [ANN] ClojureScript release 0.0-1535 with G.Closure 0.0-2029

[Evan Mezeske]

I agree with Herwig, in that if the ClojureScript JAR makes use of 
goog.async.Deferred, which is from the third party library, then the JAR 
really needs to depend on the third-party library.

I doubt that lein-cljsbuild is the only thing broken by this -- I expect 
this would break things like piggieback as well (really, anything that 
depends on ClojureScript but lacks an explicit dependency on the 
third-party stuff).

I could hack a third-party dependency into lein-cljsbuild, but I would 
prefer to just wait until a new ClojureScript is released that addresses 
this issue.

-Evan

run-jetty doesn't shut down the server after ctrl+c?

[Satoru Logic]

Hi, all.

I am playing with the `ring` library in `repl`. 

After using `run-jetty` to start a server,
I typed `ctrl+c` to send the SIGINT signal,
this ended the `run-jetty` function, but it didn't kill the server:

user=> (require '[ring.adapter.jetty :refer [run-jetty]])
user=> (require '[ring.util.response :refer [response]])
user=> (*run-jetty* (fn [request] (response "Hello world")) {:port 3000})
2012-11-14 11:44:01.892:INFO:oejs.Server:jetty-7.6.1.v20120215
2012-11-14 11:44:01.956:INFO:oejs.AbstractConnector:Started 
SelectChannelConnector@0.0.0.0:3000
^C
user=> (*run-jetty* (fn [request] (response "Save the world")) {:port 
3000}) ; now try to run it again
2012-11-14 11:44:21.358:INFO:oejs.Server:jetty-7.6.1.v20120215
BindException Address already in use  sun.nio.ch.Net.bind (Net.java:-2)

user=> 2012-11-14 11:44:21.370:WARN:oejuc.AbstractLifeCycle:FAILED 
SelectChannelConnector@0.0.0.0:3000: java.net.BindException: Address 
already in use
java.net.BindException: Address already in use


And I can still access the "Hello World" example with "localhost:3000".

Is this a bug?

Sounds like you already have a copy of the app - or another ring app -
running since the port is in use and you can still access it.

I used `ctrl+c` to close the first `run-jetty` before running the second 
one.
Maybe I'm doing it the wrong way?

Are there projects similar to meteor.js and derby.js but for clojure/clojurescript?

[Leon Talbot]

These two JS projects are bluring the boundaries between server and client.

Re: run-jetty doesn't shut down the server after ctrl+c?

[Satoru Logic]

I've found a related question on StackOverflow.

  
 
http://stackoverflow.com/questions/2706044/how-do-i-stop-jetty-server-in-clojure#2706239

What I have to do is invoking `stop` on the `server` object returned by 
`run-jetty`.

core.match - how to simplify patterns with repeated guards

[David Jagoe]

Hi all,

I have a core.match pattern that looks something like this:

(def !nil? (complement nil?))

(match [*a* *b*]
[(a :guard !nil?) nil] (dosomething a)
[nil (b :guard !nil?)] (dosomething b)
[(a :guard !nil?) (b :guard !nil?)] (dosomething a b)
:else (throw (Exception. "Not allowed"))

The point is that in every case I guard the variable using !nil?

I would like to shorten my code:

(match [*a* *b*]
[(!nil a) nil] (dosomething a)
[nil (!nil b)] (dosomething b)
[(!nil a) (!nil b) (dosomething a b)
:else (throw (Exception. "Not allowed"))

But I can't figure out how to write the !nil macro.

I've tried:

(defmacro notnil [sym]
`(~sym :guard (complement nil?)))

Which looks right in expansion:

(macroexpand-1 '(!nil foo))
-> (foo :guard (clojure.core/complement clojure.core/nil?))

But I cannot use this in a match:

(let [foo nil bar 2]
(match [foo bar]
   [(!nil foo) 2] foo
   :else :notfound))
CompilerException java.lang.AssertionError: Invalid list syntax foo in
(!nil foo)

Why!!?!??!

I guess its got something to do with the fact that match itself is a macro?

Is there some other way that I could extend match to only match when the
variable is not nil?

Thanks,
David
