Re: Simple socket programming problem

[atkaaz]

What happens if you send a newline after that Hello? ie. Hello\n since
you're using read-line

 Hello,

 I'm trying to create a very simple interaction between a client and server
 program using the server-socket library which used to be part of
 clojure-contrib and is now maintained by technomancy
 https://github.com/technomancy/server-socket/blob/master/src/server/socket.clj


 I created a simple echo server, which works fine when accessed by telnet
 but can't seem to accept messages from the python client.


 This is the code for the client and the server:

 client.py:

 import socket

 s = socket.socket()
 host = socket.gethostname()
 port = 9001

 s.connect((host,port))

 while 1:
 s.send(Hello)
 print s.recv(1024)
 s.close()


 And this is the code for the server--I tried to capture all of the input
 into a vector, but the vector never seems to change:


 (ns bot-backend.core)
 (use 'server.socket)
 (import '(java.io BufferedReader InputStreamReader PrintWriter))


 (def server
   (create-server
9001
(fn [in out]
  (binding
  [*in* (BufferedReader. (InputStreamReader. in))
   *out* (PrintWriter. out)]
(loop [input []]
  (println input)
  (recur (conj input (read-line


 The only output the client displays is a single empty vector after which
 it waits to receive more data.  Since this works correctly when I access
 the port over telnet I can't figure out what the problem is.  As a novice
 to both clojure and socket programming my best guess is that it has
 something to do with multiple threading--I know that both python and
 clojure create a new thread for each distinct socket.

 It's probably an incorrect guess. That's why I've decided to consult the
 community :D.  Any help is appreciated in advance!

Re: cyclic dependencies out of nowhere?

looks like you found it:

 Hi everyone,

 I've re-arranged some code in a project of mine and it seems I've
 introduced cyclic dependencies...It doesn't make sense though! I get the
 following message:

 = (load-file src/Clondie24/games/chess.**clj)
 Exception Cyclic load dependency: [ /Clondie24/lib/core
 ]-/Clondie24/games/chess-[ /Clondie24/lib/core ]
 clojure.core/check-cyclic-**dependency (core.clj:5430)

 presumably, that means that it tried to load chess.clj which depends on
 core.clj but while loading core.clj it detected a dependency back to chess!
 However, look at my ns declarations:

 (ns Clondie24.lib.core ;;as you can see core.clj depends on no game but
 all games depend on core.clj
(:require [Clondie24.lib.util :as ut]
  [clojure.core.reducers :as r]
  [enclog.training :as evo]
  [enclog.normalization :refer [prepare input output]])
(:import  [encog_java.customGA CustomNeuralGeneticAlgorithm Referee]
   [org.encog.neural.networks BasicNetwork]))


 (ns Clondie24.games.chess
 (:require [Clondie24.lib.util :as ut]
   [Clondie24.lib.core :as core]
   [Clondie24.lib.search :as s]
   [Clondie24.lib.rules :as rul]
   [Clondie24.lib.gui :as gui]
   [enclog.nnets :as ai]

   [enclog.normalization :as norm])
 (:import  #_[encog_java.customGA CustomNeuralGeneticAlgorithm
CustomGeneticScoreAdapter Referee]
   [Clondie24.lib.core Player]))

 Suddenly the same happens with all my games!!! If I try to load into
 core.clj directly everything goes fine...
 I should point out that there is some Java glue code which loads some
 functions from core.clj as well...In fact, that is the major change that I
 did today...I wanted the ability to genetically train all my games and thus
 the relevant functions should be in the core ns - not in chess.clj. So I
 moved them into core and now this...weird stuff!!!

 also, util.clj obviously doesn't depend on chess.clj...

 any ideas guys? I've had this error before but it was pretty obvious where
 the cycle was...Here, I'm very confused! core.clj and util.clj are the
 lowest level code and thus depend on nothing from the same project!

 thanks in advance for your time,

 Jim

Re: cyclic dependencies out of nowhere?

[atkaaz]

 I posted to make sure others reading it  know not to start looking for a
solution, since it was found - so saving their time. Also, I was sure you
were going to post it as soon as you had the time (for the same reason, at
least). I didn't mean to call you out or anything; I see making
mistakesfailing a requirement to programming: if you don't constantly fail
then you're doing it wrong ;)   (I'm still struggling to accept this though
xD)
 I only superficially looked at that commit and it seemed to me to be the
fix, now that I look again it makes some sense: in core clj you imported
Referee java class whose static init. block did a require of chess clj, but
the commit changed this require to be core. I guess this class remained
there in its old format and then interfered, as you said.

Peace out,

  hehe :)

 yep, I found it...some stupid class files had been left along with the
 java source files and they were interfering with the proper class files
 (under target/classes) since they were both under the classpath!!! I felt
 very stupid for having done this and that's why I didn't post back with the
 solution...but of course  nothing is secret, as you demonstrated :)

 btw, the commit you're showing is not exactly what fixed it...that was
 before my post I think...

Re: java.lang.Exception: Unsupported option(s) supplied: :exclude

[atkaaz]

Jim, that is in project.clj  right?
OP can use :refer and :exclude  but can't pass two namespaces to :refer,
just one

some examples from clojure code:
(ns foo.bar
(:refer-clojure :exclude [ancestors printf])
(:require (clojure.contrib sql combinatorics))
(:use (my.lib this that))
(:import (java.util Date Timer Random)
 (java.sql Connection Statement)))

or maybe you wanted this:
(ns clojure.test-clojure.data-structures
  (:use clojure.test
[clojure.test.generative *:exclude* (is)])
  (:require [clojure.test-clojure.generators :as cgen]))

  I think it is :exclusions not :exclude...

Re: Having a major problem with Maven import in Clojure and Lein Uberjar

quick note: the foo-one in local_mvn_repo (inside foo_two) is just v 0.1.0
without SNAPSHOT
the foo-one project however is 0.1.0-SNAPSHOT

 This is really important, and I am totally stumped and on a deadline.
  Help is greatly appreciated.

 I have a Clojure project called red-black, which in particular contains a
 file called interval_tree.clj

 I have been compiling this project with lein uberjar and then using the
 resulting jar in other projects by installing it in a local maven
 repository.

 mvn install:install-file  \
 -Dfile=../red-black/target/red-black-0.1.0.jar  \
 -DgroupId=self   \
 -DartifactId=red-black  \
 -Dversion=0.1.0  \
 -Dpackaging=jar  \
 -DgeneratePom=true  \
 -DcreateChecksum=true  \
 -DlocalRepositoryPath=local_mvn_repo

 The crazy thing is, I added a new function, compiled my jar and
 reinstalled it in the local maven repository of another project, and now
 java cant find my new function

 user= (red-black.interval-tree/tree-to-flat-list )
 CompilerException java.lang.RuntimeException: No such var:
 red-black.interval-tree/tree-to-flat-list, compiling (NO_SOURCE_PATH:1:1)

 However this function is in red-black.interval-tree.clj!  I even went into
 my local_mvn_repo, unzipped the jar, and looked at the interval_tree.clj
 source.  The function is in there!

 Whats even more strange is that the other function from that library are
 accessible.  For example, in my second project with the local mvn repo:

 user= (use 'red-black.interval-tree)
 nil

 Now a little tab tab magic:

 user= (red-black.interval-tree/

Re: Having a major problem with Maven import in Clojure and Lein Uberjar

ok nevermind I guess it works anyway:

user= foo-one.core/bar
#core$bar foo_one.core$bar@61526a45

I notice that lein copied that self/foo-one-0.1.0.jar into my .m2 folder
I wonder if  somehow lein didn't do that for you and you're still using the

 I have a Clojure project called red-black, which in particular contains a

 I have been compiling this project with lein uberjar and then using the
 resulting jar in other projects by installing it in a local maven
 repository.

 mvn install:install-file  \

 java cant find my new function

 user= (red-black.interval-tree/tree-to-flat-list )

 However this function is in red-black.interval-tree.clj!  I even went
 into my local_mvn_repo, unzipped the jar, and looked at the
 interval_tree.clj source.  The function is in there!

 Whats even more strange is that the other function from that library are
 accessible.  For example, in my second project with the local mvn repo:

Re: Having a major problem with Maven import in Clojure and Lein Uberjar

or let me put it this way, if I touch all the files in local_mvn_repo  and
then run lein repl (or lein deps then lein repl) the newer foo-one from
local_mvn_repo is not copied to .m2 folder, ergo I'll still be using the
existing one (I assume you already have an existing one where you didn't
define the bar fn) so check if you have the red black function in
.m2\repository\self\foo-one\0.1.0  (replace with your red black project

Re: Having a major problem with Maven import in Clojure and Lein Uberjar

[atkaaz]

ok I got the command (run inside foo-two project):
mvn install:install-file
-Dfile=../foo-one/target/uberjar+provided/foo-one-0.1.0-SNAPSHOT.jar
-DgroupId=self   -DartifactId=foo-one-Dversion=0.1.0
-Dpackaging=jar  -DgeneratePom=true
-DcreateChecksum=true  -DlocalRepositoryPath=local_mvn_repo

I actually renamed bar to bar2 and it still worked, so it definitely didn't
update the foo-one from .m2 folder (and now that I checked I am sure)

doing a lein deps in foo-two didn't fix it still... I guess simplest u can
do is delete it from .m2 and run lein repl in foo-two ? If anyone else has
any other ideas? (except incrementing verison numbers of foo-one and not
forgetting to change foo-two's project.clj to match)

In other words, lein is using the self/foo-one from .m2 not from your local
repo (but it did install it from local repo to .m2 once) though I would've
expected to recheck even though it's the same version, but perhaps it
doesn't support updating the same versions

 (set/select #(not (:dh-uuid %)) (map find-records query-parts))

 also tried the previously working example... same list

 (filter #(not (:dh-uuid %)) (map find-records query-parts))

 I am assuming that I am not indexing into each of the maps but I cannot
 remember or find out how to do this ... all examples only show one map

 Thanks

 Ray

Re: Any alternatives for these two ugly patterns?

may I see the macro for the latter, if you decide to go that way ? thx

 already have it. And just return the thing with an attribute, regardless if
 I had to add it or not.

 This version is ugly because it repeats obj three times. I could write my
 own macro to de-duplicate it, but I avoid doing that when I can because
 there's usually a better built-in solution that I just don't know about yet.

 The second is like it: (if (some-test obj) obj (some-transformation obj))

 In this one, I just want to return the object, but maybe transform it
 first. But the reference to obj happens three times! Still feels like it
 could be cleaned up.

 Any thoughts on how to clean these up?

Re: Any alternatives for these two ugly patterns?

[atkaaz]

in which case it does get evaluated twice if form:
= (pred-transform (println 1) #(not (nil? %)) #(println % .))
1
1
nil .
nil

= (pred-transform (println 1) nil? #(println % .))
1
1
nil

so maybe a let + gensym would be in order?

Re: Any alternatives for these two ugly patterns?

[atkaaz]

I wonder why the definline didn't act like a function?
= (defn pred-transform [obj pred tf]
 (if (pred obj) obj
   (tf obj)))
#'cgws.notcore/pred-transform
= (pred-transform (println 1) #(not (nil? %)) #(println % .))
1
nil .
nil
= (pred-transform (println 1) nil? #(println % .))
1
nil

= (fn? pred-transform)
true
= (definline pred-transform [obj pred tf]
   `(let [o# ~obj]
  (if (~pred o#) o#
   (~tf o#
#'cgws.notcore/pred-transform
= (fn? pred-transform)
true

 Seems to me that (merge {:attr something} obj) answers the OP's question,

 something is expensive to compute (or has side effects that should only
 happen if it winds up in the output!) then another method needs to be used.

 yes that is what you do to avoid double-evaluation...:) I was making a

Re: asm-based clojure yet?

Re: How to: reduce boolean operations?

[atkaaz]

Thank you, I see it now. Based on your comment I actually took at look at
the source code for every? (haven't checked it before, oddly enough)

= (source every?)
(defn every?
  Returns true if (pred x) is logical true for every x in coll, else
  false.
  {:tag Boolean
   :added 1.0
   :static true}
  [pred coll]
  (cond
   (nil? (seq coll)) true
   (pred (first coll)) (recur pred (next coll))
   :else false))
nil

I thought that by coll in the doc they meant coll? returns true on the
input...
But now I see that first does a seq on that coll which does what you said
and thus returning a vector

So these mean nothing:
= (seq? {:a :b :c :d})
false
= (coll? {:a :b :c :d})
true
= (seq? [:a :b :c :d])
false
= (coll? [:a :b :c :d])
true

= (first [:a :b :c :d])
:a
= (first {:a :b :c :d})
[:a :b]
= (first {})
nil
= (first [])
nil ;if this were me I'd probably choose to throw here
 ;or return all values in a vector to differentiate from the following:
= (first [nil])
nil


It kinda makes sense except I wouldn't have expected that on the map it
would return a vector (but then how else could it return both key and value
right? )  so everyone expects the input to the pred would be a vector
when passed in a map.

oops stumbled upon another one:
= (get [1 2 3] 0)
1
= (get [1 2 3] -)
nil
= -
#core$_ clojure.core$_@2b0dfb46
Yep definitely better than throwing  *sarcasm*

ok check this:
= (every? nil? nil)
true
= (every? nil? [nil])
true
= (every? nil? [])
true

= (every? true? [])
true
= (every? true? nil)
true
= (every? true? [nil])
false

= (first nil)
nil
= (first [nil])
nil
= (first [])
nil


makes me think of C or something


(ok i'll stop if nobody brings it up, but really thanks to everyone that
replies - and sorry for hijacking the thread)

 Usage:  (every? pred coll)

 (see http://clojuredocs.org/clojure_core/clojure.core/every_q )

 Function *every?* expects a predicate and a collection.  Converting the
 map {:a 1} into a collection returns a sequence of 2-element vectors:

 user= (seq  {:a 1})
 ([:a 1])

 Calling the function :a on a vector returns nil, since keyword lookup only
 works for maps.  every? then converts the nil into fase:

 user= (every?  :a  [ nil ] )
 false

 To rephrase the point I was making previously, (false x) is a truthy
 value for any x in [] is a true sentence, indeed trivially so because
 [] is empty. Thus (every? false []) returning true totally makes
 sense.

 Alright, I see what you mean and you are right. But let's just state
 some assumptions(which I see as conventions):
 - the system that you're using (be it logic or mathematics or whatever it
 is) to evaluate that that proposition is truthy  is assuming(without
 checking) that the components are correct (such as false being a pred)
 - when the collection is empty - returns true   (this is a convention
 imho)
   I see this system as being incomplete/incoherent/inconsistent(or insert
 the right word here) because of those.
 (false x) is a truthy value for any x in []
 so that is a true sentence as you say, in this system(can I call it

 Thank you, I see it now. Based on your comment I actually took at look at
 the source code for every? (haven't checked it before, oddly enough)

 = (source every?)
 (defn every?
   Returns true if (pred x) is logical true for every x in coll, else
   false.
   {:tag Boolean
:added 1.0
:static true}
   [pred coll]
   (cond
(nil? (seq coll)) true
(pred (first coll)) (recur pred (next coll))
:else false))
 nil

 I thought that by coll in the doc they meant coll? returns true on the
 input...
 But now I see that first does a seq on that coll which does what you said
 and thus returning a vector

 So these mean nothing:
 = (seq? {:a :b :c :d})
 false
 = (coll? {:a :b :c :d})
 true
 = (seq? [:a :b :c :d])
 false
 = (coll? [:a :b :c :d])
 true

 = (first [:a :b :c :d])
 :a
 = (first {:a :b :c :d})
 [:a :b]
 = (first {})
 nil
 = (first [])
 nil ;if this were me I'd probably choose to throw here
  ;or return all values in a vector to differentiate from the following:
 = (first [nil])
 nil


 It kinda makes sense except I wouldn't have expected that on the map it
 would return a vector (but then how else could it return both key and value
 right? )  so everyone expects the input to the pred would be a vector
 when passed in a map.

 oops stumbled upon another one:
 = (get [1 2 3] 0)
 1
 = (get [1 2 3] -)
 nil
 = -
 #core$_ clojure.core$_@2b0dfb46
 Yep definitely better than throwing  *sarcasm*

 ok check this:
 = (every? nil? nil)
 true
 = (every? nil? [nil])
 true
 = (every? nil? [])
 true

 = (every? true? [])
 true
 = (every? true? nil)
 true
 = (every? true? [nil])
 false

 = (first nil)
 nil
 = (first [nil])
 nil
 = (first [])
 nil


 makes me think of C or something

 Usage:  (every? pred coll)

 (see http://clojuredocs.org/clojure_core/clojure.core/every_q )

 Function *every?* expects a predicate and a collection.  Converting the
 map {:a 1} into a collection returns a sequence of 2-element vectors:

 user= (seq  {:a 1})
 ([:a 1])

 Calling the function :a on a vector returns nil, since keyword lookup
 only works for maps.  every? then converts the nil into fase:

 user= (every?  :a  [ nil ] )
 false

when you say the word false I'm assuming you're referring to false? the
function (not false the boolean value), otherwise I don't understand

so like: What matters is that *false?* returns truthy values when called
with any members of []
makes sense to me.

So all I was saying above is that it should throw when [] is empty just as
it does when [] is not empty, but it doesn't throw when empty because it's
never called (by it i mean false not false?)

= (type false)
java.lang.Boolean
= (type false?)
clojure.core$false_QMARK_
= (fn? false)
false
= (fn? false?)
true

But really, if you were not talking about false? then I don't get it (??)

 Whether (false 1) or (false true) is truthy is irrelevant. What
 matters is that false returns truthy values when called with any
 members of [], which is of course the case, as [] has no members. (For
 it not to be the case, there would have to exist an x in [] for which
 (false x) were not truthy -- clearly there is no such x.)

 This is the same story as with quantification restricted to the empty set:

   \forall x \in \emptyset . \phi(x)

 is true regardless of what \phi is, and intimately related to how
 implication works in classical logic (since the above is shorthand for
 a formula involving implication):

   x - y

 is true when x is false, regardless of what value y takes. (It's also
 true when y is true, regardless of what value x takes; this, however,
 is not relevant here.)

bugs which can be hard to track down. There's no guarantee that someone
sometime will pass the wrong param either being aware of it or not and
depending on the case it may go unnoticed and/or throw in a different place
which seems quite unrelated to where the bug actually is.
  Anyway, I'm lingering, simply put: you're right   using your system of
evaluation, but not when using mine; mine says: make sure everything is
consistent within its own definition (so 1 above must be checked if it
really fits the pred pattern (ie. is that a pred; is the entire
proposition(or call) syntacticallysemantically valid), if it doesn't the
the entire call is invalid and should/will throw) and I will add to that:
 that if the collection is empty then also throw, for it doesn't make
sense(to me) to check an empty collection (which you sort of assume is non
empty by the name every?) for a predicate, and therefore you are kind of
forced to use a convention(aka if empty return true) if you want to not
throw in this case. (yep I would really throw on empty collection, for if
you got to where you accidentally called every? on an empty collection
you're way past the point in the caller where you should've checked for an
empty collection anyway - that is, if you care about handling all(or most?)
cases for the purpose of your program being consistent)


So, assuming non-empty collections are the norm, we get an exception
 either way -- would having the exception come from every? rather than
 the attempt to call the not-really-a-predicate object be of much help
 in debugging?

I find it would be more consistent to throw from every? as if it makes the
check that all its inputs are correct (so making sure pred is a pred ie. a
fn  and not a value - that can't be used as a pred at least like a :keyword
could)
And also, as I said above, I'd throw when empty collection too (but that's
never gonna happen in clojure, I understand that especially because of what
John D. Hume said in an above post - makes sense(if you want to get things
done especially), but that is not my way(hence why I got nothing done so
far - so the joke's on me :) ))

wait, shouldn't this work?
= (:a {:a 1})
1
= *(every? :a {:a 1})*
false
= (coll? {:a 1})
true


;well at least this one works:
= (every? {:a 1} [:a])
true
= ({:a 1} :a)
1
;so I'm probably missing something

On Mon, May 20, 2013 at 4:02 AM, Daniel P. Wright d...@dpwright.com wrote:

 Hello,

 I am trying to structure the game loop for a simple game in clojure,
 trying to keep things pure as far as possible to get a feel for how this
 would work in a functional environment.  Currently, I am working with
 a message-based system, whereby various events create messages which I
 then act on to change state.  For example:

   1. Read keypresses, generate a message for each keypress and add to
  the queue.
   2. Read from the network; add any incoming messages to the queue.
   3. Add an update message to the queue which can be used for generic
  update processing: AI, physics, whatever
   4. Go through the entities in my world delivering these messages as
  appropriate.  Keypress and update messages will be processed by any
  entity that implements a handler for them; network messages may be
  directed so that they only get sent to a specific entity.
 (The return value of the functions processing these messages is
  itself a vector of messages, such as update-state to replace the
  current state of an entity (position, etc) with a new state, or
  perhaps a message to send information over the network.)
   5. Send any outgoing network messages, perform any state updates, etc.
   6. Draw the screen, return to 1 and begin the next game loop.

 The issue I'm having is that this system results in rather a lot of
 looping through every entity in the world.  There are two full loops,
 delivering the messages in step 4 and updating the state in step 5.
 Originally I had the message handlers in step 4 return a new state
 rather than new messages, so I just updated the entities in-place during
 the first loop, but I found sometimes I wanted to do other things than
 just update state -- for example send messages over the network, or to
 another entity in the world.  So it seemed more flexible to return
 messages, even if some of those messages are directed toward the entity
 sending it.

 My other issue is that with messages intended to be processed by a
 particular entity, I can either check that while looping through the
 whole list of entities (which means for every entity it's not intended
 for I'm running a wasteful check on the id of a message), or I can put
 the entities in a map instead of a vector and look them up by some id
 instead (in which case I'm doing a search for every directed message, on
 top of the loop I'm already doing through all the entities).

 I've come from a mostly C++ background, so my sense of when I'm doing
 something really bad isn't very well-tuned in functional languages at
 the moment.  I write something that feels nice and looks pretty, and
 then I step back and think about what it's actually *doing* and I can't
 help but think in C++ this would be unforgivably vile.

 It seems the more I try to push function purity the more I have to loop
 through some monolithic data structure holding all of my state, since I
 can't just pass references around and modify them in-place.  Writing the
 code for the entities themselves is going quite well -- I am keeping
 their functions pure, not referring to anything outside of the
 parameters they're passed in, and thus always returning the same result
 given the same input, and limiting their input to the information they
 need without giving them access to the entire state of everything -- all
 of which is great for testing, parallelisation, and all the rest.  It's
 at the higher level of managing the collection of these entities and
 their relationships that I wonder whether I am working along the right
 lines or whether I am in some sense doing it wrong.

 As an aside, right now I am avoiding storing entity state as atoms and
 having the update functions modify those atoms because although clojure
 helps update their values safely it still means the function has side
 effects, and I'm trying to keep functions as pure as possible at least
 until I can understand the limitations of doing that and see the
 necessity for using global constructs.

 I have a feeling this is only going to get more complex as I start
 wanting to make smaller sub-lists that refer to the same entities.  For
 example my entities may be stored in some tree format in the world
 state, but I might want to have a list of all enemies within a certain
 radius or whatever just as a convenience for quick access to those
 entities I'm interested in.  Right now if I updated an entity in this
 list it would remain not updated in the global state tree... I'm
 guessing there's no way around holding an atom or similar in both lists
 and

i though expr. is the short for of the word expression which requires a

 The next-to-last sentence describes the behavior you're talking about. The
 last sentence is addressing the no-args case. Starting a sentence with a
 parenthesized form makes it hard to read.

Re: [ANN] tawny-owl 0.11

[atkaaz]

For those who don't know the concepts (aka me) can we get a working example
of what can be done ? I'm having a strange feeling that ontologies(although
I've never heard the word/idea before except from you) might be something
similar to what I am searching for...

Possibly an example that showcases everything that can be done ? though
that might be too much to ask, or perhaps suggest a link url to something
that might help (me) understand ?

Thanks.

 I'm pleased to announce the release of tawny-owl 0.11.

 What is it?
 ==

 This package allows users to construct OWL ontologies in a fully
 programmatic
 environment, namely Clojure. This means the user can take advantage of
 programmatic language to automate and abstract the ontology over the
 development process; also, rather than requiring the creation of ontology
 specific development environments, a normal programming IDE can be used;
 finally, a human readable text format means that we can integrate with the
 standard tooling for versioning and distributed development.

 Changes
 ===

 # 0.11

 ## New features

 - facts on individual are now supported
 - documentation has been greatly extended
 - OWL API 3.4.4


 A new paper on the motivation and use cases for tawny-owl is also
 available at http://www.russet.org.uk/blog/2366

 https://github.com/phillord/tawny-owl

 Feedback welcome!

Re: asm-based clojure yet?

[atkaaz]

thank you very much, my search has lead me to seeking a lisp that could
compile to machine code (mainly because i cannot accept the 20-22 sec `lein
repl` startup time and eclipse/ccw memory consumptions - so I was hoping
for something fast even though the cost is portability and all else)

 It's hard to really appreciate java and clojure until you actually write
 some C/C++ or ASM.. I have some minor experience with that stuff, and it
 still haunts me from time to time.

 Sometimes we make tradeoffs without knowing we did.  By choosing a
 language, or having the choice made for us, we accept a set of abstractions
 as our bottom level of thinking for a problem-space.  Only old-timers and
 people that make a point to care about low-level stuff will notice the
 implications of what they're doing along the abstraction stack.  People
 with ingrained habits just won't find it easy to think functionally, but
 I'm young and irreverent, so it doesn't bother me :-).

 C++ is fun because of all the bolted-on kludges that 'mitigate' these
 problems.  You can use operator-overloading on pointer operations to
 perform automatic reference counting, deallocating objects when things that
 point to them go out of scope, but I think implementing a PersistentHashMap
 this way would be very difficult.  Also, pretty sure it can't handle cycles.

 I guess the point is, I appreciate any effort to understand such issues,
 it's been a useful thing for me to know in the 0.05% of time that knowledge
 is needed.

 But, people who don't know just won't be able to get past those problems.
  And, you generally can't easily find a _really_ full-stack guy to glance
 at it for you when it would be useful to have one.

 100'000s of terms.

 My example Pizza ontology shows it in use.

 (defclass MozzarellaTopping

 and finally,

 (defclass MargheritaPizza

 and the reasoner will work out that MargheritaPizza is a CheesyPizza.

 In itself, this is simple, but you can build up more complex classes
 like so.

 (defclass VegetarianPizza

   (owlnot
(owlsome hasTopping MeatTopping))
   (owlnot

 (defclass NonVegetarianPizza

 Of course, really takes flight when you have large ontologies. FMA which
 models human anatomy, has I think, about 100,000 terms. SNOMED (ways you
 can get ill) has millions.

 Now there are lots of tools for building these; the novelty with tawny
 is that the raw syntax is relatively simple (most of tawny-pizza does
 not look like a programming language), but it is entirely programmatic;
 so, it is possible to automate, build patterns, and integrate with
 external infrastructure all in one place. I think that this is going to
 be very useful, but we shall see!

 While I am interested in biomedical and scientific ontologies, there are
 lots of other applications. Probably the most famous one at the moment
 is Siri (the iphone thingy) which is ontological powered underneath.

 There are quite a few articles, varying in scope on ontologies on
 ontogenesis http://ontogenesis.knowledgeblog.org.

 It is a very valid point, though. I should write some documentation on
 ontologies for programmers. I shall work on it!

Would you say that ontologies can be modeled on top of graphs? so in a way
they can be seen as a specific use case for graphs? (maybe directed acyclic
graphs), that's what I am getting the sense of so far

Re: How to: reduce boolean operations?

there's another edge case when using and/or :
 getting passed an unbound var  where for example `nil?` and `str` applied
to it don't throw, and of course also `or` and `and`, ie.:

= (def a)
#'cgws.notcore/a
= a
#Unbound Unbound: #'cgws.notcore/a
= (nil? a)
false
= (str a)
Unbound: #'cgws.notcore/a
= (or a)
#Unbound Unbound: #'cgws.notcore/a
= (or 1 2 a)
1
= (or a 1 2)
#Unbound Unbound: #'cgws.notcore/a
= (and 1 2 3 a)
#Unbound Unbound: #'cgws.notcore/a
= (and a 1 2 3)
3

= (type a)
clojure.lang.Var$Unbound

= (cond a 2)
2
= (when a 3)
3
= (if a 4 5)
4

= (bound? #'a)
false
= (bound? a)   ; in case anyone was wondering
ClassCastException clojure.lang.Var$Unbound cannot be cast to
clojure.lang.Var  clojure.core/bound?/fn--4837 (core.clj:4954)

= (defn test1 [input]
 (cond (and (not (nil? input)))
   (println received nice input=` input `)
   :else
   (throw (RuntimeException. (str bad input: input)
#'cgws.notcore/test1

Re: asm-based clojure yet?

[atkaaz]

Looks like I forgot to enable the paging file (windows virtual memory was
disabled) and that is why my eclipse/firefox would crash when running out
of memory  and also had much eclipse.ini memory allocated -Xms228m -Xmx712m
; and because of all these I was unable to start repl most of the time in
ccw due to not enough memory(it said), so due to your comment (thank you),
I've fixed those and set -Xms128m -Xmx512m but will probably go back to 712
(it's ok now since I've the paging file); but the memory total is like
3.5gig since 512 is eaten by video card memory.

So now at least I can run them without running out of memory all the time
:) but they still use quite a lot and I found myself having to run lein
commands (like lein test) and restarting repls enough times for it to make
me want something else - but I am an odd ball, so it's not something
everyone else will do.

Honestly I really want a system where things are more accessible,
unfortunately I can't explain this (i'll try if u really want me to) for
example I really enjoyed the F3 in eclipse on java source code which would
do Go to Definition/Declaration (of this identifier), and also the find all
calls to this method in this project and the refactoring... this kind of
connectivity I'd expect to be in the system (from what I've read some Lisp
machines(?) or the lisp lang on some machines really have that was it
Genera ? and some read about Dynamic Windows  but I also remember something
vaguely about ruby - haven't used it though). In a more broader way, I want
to be able to explore/deduce the system without having to jump through
hoops like googling for information about it, when in fact I already have
it running on my system, why not just explore its construction live while
it's running, visualize all its connections (like in a graph)

I like this clojure lang because it gets me closer to the way I want things
to be, but it feels all so disconnected like I can't feel that when writing
some code I can just easily F3 on a symbol and see where else it was used
or even defined(sometimes this works in ccw btw ie. for clojure core code)


So far, I'm thinking maybe code something from assembler level up (maybe
even not requiring garbage collector but still not using explicit mem
allocations like malloc) so it will eventually become a replacement for
whatever I use for text editor, and if it does the way I think it will, I
can then store all kinds of information and advance it even to the next
level... but there's all these barrier with transactions and locks but this
functional programming idea might be pretty good to apply(even though I
envisioned a system where everything would be global(ly accessible)
restrictions can still apply in dependency style like A depends on B and C
depends on B, so if I want to change B then the way A and C depend on B
have to be satisfied before the change can occur or that change will have
to include changes to A and/or C also).


Sorry for the rant, it's just that i feel lost so far(and not very
knowledgeable). I just imagine how awesome it would be to can explore a
system (PC+OS+java+clojure+some window+some text+some word on it) of which
say you know nothing of, from a point (any point you choose) and be able to
understand it and see how everything interconnects to everything else (no
data/level/layer stripped just like the .exe is without the sourcecode for
example), because everything you need is there, visually explorable(maybe
graph like) and even changeable, if you just need to know exactly how is
some word(or even a pixel) on the screen connected to everything else for
example you could dig in - I don't know how it would look and how to
implement that so far, but i know I want it, and apparently I'm reluctant
to accepting the status quo even though that's the only way to get there :/
It can still be fast even though all the debug info (so to speak) and
source code is tagged/connected to the binary code/offsets  I imagine.

 The above strikes me as a slightly odd statement. Eclipse/CCW or lein repl
 startup times should be irrelevant because you should only be incurring
 them once, when starting a development session. Sure, Eclipse eats memory
 too, but again this is only a development time issue and your dev machine
 should have plenty, right?

 In production, running the packaged .jar file should be pretty quick and
 much more lightweight. JVM startup is less than 0.1sec nowadays, so you can
 get a splash screen or basic GUI up in front of a user almost immediately.
 That only leaves

Re: How to: reduce boolean operations?

Well, seems to me more like this:
if [] is empty then return true
otherwise check (pred everyx in coll)
however this allows for any pred especially(in this case) invalid preds:
`false` is not a function/pred
= (false 1)
ClassCastException java.lang.Boolean cannot be cast to clojure.lang.IFn
cgws.notcore/eval2542 (NO_SOURCE_FILE:1)
= (false true)
ClassCastException java.lang.Boolean cannot be cast to clojure.lang.IFn
cgws.notcore/eval2564 (NO_SOURCE_FILE:1)

doesn't seem truthy to me

Re: confused on set!

[atkaaz]

The following idea came to me in the shower, sort of out of the blue, and I
don't know why I didn't think of it before(I'm disappointed with myself)
so, why not use the same thing as clojure does? even though it does it in
java, you can do it in clojure, the only thing is that you have to do it
once, probably where you define the var, such as(well unfortunately it
doesn't work O_o maybe someone can explain?):
(I was gonna try java interop but I notice there's *
clojure.core/push-thread-bindings*)

=* (def ^:dynamic *test4* false)*
#'cgws.notcore/*test4*
= *(push-thread-bindings {#'*test4* true})*
nil
= **test4**
*false*
= (pop-thread-bindings)
nil
= *test4*
false

= (def ^:dynamic a 1)
#'cgws.notcore/a
= (push-thread-bindings {#'a 2})
nil
= a
1
= (set! a 3)
IllegalStateException Can't change/establish root binding of: a with set
clojure.lang.Var.set (Var.java:233)

(defn *push-thread-bindings*
  WARNING: This is a low-level function. Prefer high-level macros like
  binding where ever possible.

  Takes a map of Var/value pairs. Binds each Var to the associated value for
  the current thread. Each call *MUST* be accompanied by a matching call to
  pop-thread-bindings wrapped in a try-finally!

  (push-thread-bindings bindings)
  (try
...
(finally
  (pop-thread-bindings)))
  {:added 1.1
   :static true}
  [bindings]
  (clojure.lang.Var/pushThreadBindings bindings))
nil

=* *clojure-version**
{:interim true, :major 1, :minor* 6*, :incremental 0, :qualifier master}


so if this worked as I expected then the following two statements would be
in the same place:
= (def ^:dynamic *test1*)
#'cgws.notcore/*test1*
= (push-thread-bindings {#'test1 default value here})
nil

;and the third could be anywhere (in current thread, 'cause just as
clojure's *warn-on-reflection* when on a different thread you still can't
set! it)
= (set! test1 user value)
IllegalStateException Can't change/establish root binding of: test1 with
set  clojure.lang.Var.set (Var.java:233)

*So, is **push-thread-bindings broken(unlikely) or am I missing
something(most certainly so) ?*

Re: Why are errors in nested futures suppressed?

= @(future (swap! atom inc 0))
ClassCastException clojure.core$atom cannot be cast to clojure.lang.Atom
clojure.core/swap! (core.clj:2161)


(both in ccw, but i notice that the first statement does throw in lein repl)

guessing the error is actually thrown in that thread, but nobody can see it
unless they are trying to deref it in current thread or something else
along those lines



On Tue, May 21, 2013 at 1:01 PM, Colin Yates colin.ya...@gmail.com wrote:

 Hi all,

 If the function executed in a future throws an error it is printed out in
 the repl immediately.  If that function is executed in a future which
 itself is executed in a future then it isn't.

 For example, imagine somebody wrote the following code (please, suspend
 belief and just accept people do do this when learning Clojure :)):

 [code]
 ;; some silly code
 user (swap! atom inc 0)
 ClassCastException clojure.core$atom cannot be cast to clojure.lang.Atom
  clojure.core/swap! (core.clj:2161)
 ;; silly code wrapped in a future
 user (future (swap! atom inc 0))
 ClassCastException clojure.core$atom cannot be cast to clojure.lang.Atom
  clojure.core/swap! (core.clj:2161)
 ;; silly code wrapped in a future wrapped in a future
 user (future (future (swap! atom inc 0)))
 #core$future_call$reify__6267@11e55d39: :pending
 user
 [/code]

 My understanding is that future executes its delegate in a separate
 thread, hence the (future (swa...)) code prints out the exception almost
 immediately.  I don't understand why the nested future doesn't print out
 the error though as it should surely be executed almost immediately as well?

 Of course, if you dereference the call then it prints out the stack trace.

 As to why you would want a future in a future...that is a different kettle
 of fish :).

wouldn't this be an interesting clojure code editor?

[atkaaz]

Hi guys. I just stumbled upon something [1] and the editor is quite similar
to what I was hoping/focusing on having(these days) for editing/writing
(not just) clojure code.
 What are your thoughts on this? (just don't think too much of it in that
is for java and ignore the 3D thing)

To see what I mean, please see the second video on that [1] page (it's 12
minutes), or if you don't have flash and can get the .wmv file from [2]

[1] http://www.alice.org/index.php?page=what_is_alice/what_is_alice
[2] http://www.alice.org/what_is_alice/AliceDemonstrationVideo.wmv

to note the different colors for forms within a form (ie. at minute 8:57 in
the video)
I especially wanted something very similar in ccw so it would be obvious
where each form begins (which is currently being done with colored parens i
think)

unlicensed clojure code/jar/uberjar ?

[atkaaz]

Hi. Can I release my clojure code under unlicensed?

Maybe the code and the jar can be, right? But how about the uberjar which
includes clojure itself which is under EPL?(for example I cannot dist the
uberjar under GPL) Is my code being unlicensed like that work ok with
clojure's EPL? Or does EPL prevent this? so in effect then I cannot
distribute the uberjar, but can the jar or just my code
(by jar I mean *lein jar*)
(by uberjar I mean *lein uberjar*)

 You can but it's not a very good idea. Not all countries have the notion

Could you elaborate on this:

 It is extremely unlikely that folks in large companies will be able to use

Re: unlicensed clojure code/jar/uberjar ?

[atkaaz]

I see what you mean about public domain  here for example:
http://www.mingw.org/license
*MinGW Runtime:* All releases of the MinGW base runtime package, prior to
release 4.0, have been placed in the public domain, and are not governed by
copyright. This basically means that you can do what you like with the code.

Due to inadmissibility of the public domain concept, in certain
jurisdictions, we have now chosen to adopt a MIT style license for the
principal components of the MinGW runtime, from release 4.0 onwards; you
may view this LICENSE, as it is filed in the source code
repositoryhttps://sourceforge.net/p/mingw/mingw-org-wsl/ci/21762bb4a1bd0c88c38eead03f59e8d994349e83/tree/LICENSE

 Hi. Can I release my clojure code under unlicensed?
 http://unlicense.org/


 You can but it's not a very good idea. Not all countries have the notion
 of public domain.
 It is extremely unlikely that folks in large companies will be able to use
 code released
 under such an exotic license.

  I'd recommend Eclipse Public License or Apache Public License 2 if you
 care about
 your project adoption in circles other than hobbyists and free software
 radicals.

 * M-x load-theme whiteboard  (for high contrast)
 * M-x htmlfontify-buffer (and save)

 Yes, I know I can just take a screenshot, but that gives you a bitmap that

Re: Strange exception intializing clojure.core using Spring-Hadoop

[atkaaz]

I've some idea, but it may not be right; I'm thinking that clojure needs
its own classloader and if that spring thing overriden it somehow, it's not
going to work initing clojure, just like in minecraft bukkit server with
clojure-based plugins, ie. https://github.com/CmdrDats/clj-minecraft/
 I'm thinking maybe you need to do something similar with temporarily
restoring clojure's classloader when clojure inits or something like that
(I don't remember) but you may look at the code in clj-minecraft like here:
https://github.com/CmdrDats/clj-minecraft/blob/master/javasrc/cljminecraft/BasePlugin.java#L56

What clojure version were you using when the above stacktrace happened?

Re: Strange exception intializing clojure.core using Spring-Hadoop

looks like it didn't properly load clojure.core (possibly due to that
classloader being wrong?) but I am not sure why it didn't fail sooner
than on the line with refer

static void doInit() throws ClassNotFoundException, IOException{
load(clojure/core); //this wasn't loaded ok?!

Var.pushThreadBindings(
RT.mapUniqueKeys(CURRENT_NS, CURRENT_NS.deref(),
   WARN_ON_REFLECTION, WARN_ON_REFLECTION.deref()
,RT.UNCHECKED_MATH, RT.UNCHECKED_MATH.deref()));
try {

Symbol CLOJURE = Symbol.intern(clojure.core);

Var in_ns = var(clojure.core, in-ns);
Var refer = var(clojure.core, refer);
in_ns.invoke(USER); //wonder why it didn't fail here

 I don't have a main entry point. And, yes, I want global-state for
 exactly the same reason that Clojure does. I have a process that
 produces logging output, and I want the user to be able to define
 where that output goes. Basically, the same as doing:

 (set! *out* some-sensible-value)

 but different because I also want to be able to choose between a
 GUI output, and text.

 So, I guess, my two options are:

 (reset! *can-we-change-it* Paul)

 (println @*can-we-change-it*)

 (binding [*can-we-change-it*
   (atom George)]
   (println @*can-we-change-it*))


 (println @*can-we-change-it*)



 (def
   ^{:dynamic true}
   *can-we-change-this-one* Mick)

 (println *can-we-change-this-one*)

 (alter-var-root #'*can-we-change-this-one*
 (fn [x] Keith))

 (println *can-we-change-this-one*)

 (binding [*can-we-change-this-one*
   Bill]
   (println *can-we-change-this-one*))

 (println *can-we-change-this-one*)



 Of which, I think, the former is the best option, although it's going to
 break my existing code which uses binding forms.

Re: confused on set!

[AtKaaZ]

you're right, I somehow didn't read what he was using it for, just looked
at the examples he gave and assumed generic var

In a way I'm in his shoes, but I always assumed that the user would use
binding even if that meant encompassing the whole program in it. Like if
you wanted to disable asserts  ok bad example since set! works for this
too, but I have something like that and I was ok with the idea that the
user would use binding around the whole code to set that.
 Maybe I should consider other alternatives... but now I can't think:)

 A bit off topic but I remember when Clojure came out, STM was the big
 selling point! I've been programming Clojure for more than 3 years now and
 I've yet to write code that uses STM but that wasn't intentional...I just
 did not need to (slightly ironic I find)... :)

 dynamic scope is another story though...I very much intentionally stayed
 away from it!

Re: [ANN] getclojure.org

[atkaaz]

Ok fair enough. I was wondering however how hard would it be to add a
button maybe? or a var to the url? (or a button which adds the var to the
url - not sure how these are called) which would switch between the
default(as it is now) and the pretty printed output (for all the results
not just one of them)

  At the moment, yes. The docstrings are not pretty, but in the end I
 decided that seeing the literal \n was better than pretty printing captured
 output.

 That being said, I'm not strongly opposed to changing it (patches
 welcome), but right now I think not pretty printing output is good in the
 80-90% case.

Re: confused on set!

[AtKaaZ]

I think the answer is in RT 's doInit
Var.pushThreadBindings(
RT.mapUniqueKeys(CURRENT_NS, CURRENT_NS.deref(),
   WARN_ON_REFLECTION, WARN_ON_REFLECTION.deref()
,RT.UNCHECKED_MATH, RT.UNCHECKED_MATH.deref()));

it basically does a
(binding [*warn-on-reflection* currentvaluehere])
where currentvaluehere is false

so it's like:
(binding [*my-test1* *my-test1*]
  (set! *my-test1* true))

basically set! works because you're not seeing the root binding, you're
inside a binding already, at least that's what I'm getting out of it.

Which leads you to the following:
user= (.start (Thread. (fn [] (do (set! *warn-on-reflection* true)
(println inthread)
Exception in thread Thread-12 java.lang.IllegalStateException: Can't
change/establish root binding

 I'm still a bit confused on the use of set!

 I would like to define a configuration variable that is easy to change,
 but which is not critical to my infrastructure; it's will set some
 default behaviours.

 Now, I can do things like

 (binding [*warn-on-reflection* true]
   (do-some-function))

 and it does the right thing. Similarly, I can do

 (def ^{:dynamic true} *my-test* false)
 (binding [*my-test* true]
  (do-some-function))

 and this all works.

 However, while I can do

 (set! *warn-on-reflection* true)

 I cannot do

 (set! *my-test* true)

 because I cannot change the root binding. What I confused about is how
 does this work with *warn-on-reflection*? Where is the root binding? And
 how come I am not trying to set it also? Can I get similar behaviour for
 one of my vars? Or do I need to do something like:

 (def *my-test* (atom true))
 (reset! *my-test false)

 but then I loose my dynamic binding?

unusual question: how do you get morale?(or moral support)

[AtKaaZ]

Hi. I've been meaning to ask (all of)you, how do you get moral support? How
do you put yourself into that mood so that you're happy/willing to program?
What motivates you to do it? Is it the people you surround yourself with or
the financial support? Are they enough to subconsciously motivate you? What
if you had no friends/contacts but you had time?

 Unusual question for this ML, I know, so I won't expect (m)any answers.
Thanks.

Re: unusual question: how do you get morale?(or moral support)

[AtKaaZ]

Hey, thanks for sharing.

 I think I am the opposite of that, I am unable to code just for myself, if
no one else is directly (and immediately) impacted by what I do then I get
bored fast (but this is probably coupled with the fact that I am unable to
code the way I want yet like some editor where everything is based on a
graph so ie. connected, explorable). If I am doing something for someone
(other than just myself) then I'm all fired up and motivated although any
kind of inconsistency/bugs/barriers or the need to compromise around them
because of the system limitations are having a negative impact on my
morale.
 This is likely still be ego related, but knowing that I am not the only
one that I program for, boosts my morale. In a way this is always true that
you program for others as much as for yourself but it's not directly
obvious, for example all the improvements that you get from
practicing/programming will help you and others in the future, it's for the
best of all(and I consciously know that), but my subconscious seems to want
something more immediate like knowing that are others (in the now) actively
waiting on me and wanting me to code the stuff (ego xD). I find this
morale boosting. But just doing it for myself, I couldn't do it, even if I
would know that sometime in the future some people would appreciate that I
did that.
 I would guess that a good programmer(not me) knows how to program his
subconscious (which is not unlike what you did Mosciatti) so that morale is
never a problem. Either make the environmental conditions match the
expected ones (ie. surround yourself with friends that appreciate what u're
doing) or reprogram your subconscious (ie. so you don't need the friends
that appreciate you, you appreciating yourself would be enough).
  Sometimes I am able to trick myself into believing that sometime in the
future some people would benefit from what I coded (either from the code
itself[less likely though xD] or from what the resulting program does) and
this works for a while but it's still based on the fact that I code for
others or in other words, my ego boosts morale when I know that I've done
something for others (as opposed to just myself).

ok writing too much text, stopping

 I code only for myself, and honestly coding is what I like to do.

 I remember these days being in a very bad mood and all I wanted to do was
 to sit and code.

 I believe that what motivate myself is my own EGO, code for me is only
 about solving problem, and more problem I solve better my ego is.

 Anyway I am still a student and I don't have (m)any [I like that XP]
 financial issues.

 I am weird, but friends usually don't help me when I have an hard time,
 neither does my family (no that they wouldn't like to help me, they try
 most of the time but they simply don't work), time helps.
 For problems that I can not solve because they are not ups to me, I just
 don't think about, so I keep myself as busy as possible, until I don't feel
 great again.
 For problems that I can solve, well those are just other forms of coding,
 so I just fix that for my ego.

 :-)

 Someone else want to share ?

 therefore better (imo :) )

 Maybe one could say that, generally, in Clojure it's more meaningful
 to work with truthy values instead of the boolean true... ?

Re: A JMonkeyEngine3 wrapper?

[AtKaaZ]

Robert, do you have all that in a project somewhere on github? I really
enjoy all the explanations


On Fri, May 3, 2013 at 7:19 PM, Robert Louis McIntyre r...@mit.edu wrote:

 I've written some JME3 wrapper code for my thesis project -- it's not
 ready for prime time, but it's got some nice ideas.

 The design goal is to try and make my thesis code concise instead of
 being a general purpose library, but one idea I like it to build a
 world out of clojure functions that do the updating, etc.

 relevant pages for this project (with code) include:

 http://aurellem.org/cortex/html/world.html
 http://aurellem.org/cortex/html/util.html

 and some more at http://aurellem.org

 This is for a slightly older version of JME3, but things should mostly
 still work for the latest version.

 sincerely,

Re: I tripped out

[AtKaaZ]

yes, thank you, that is what I was referring to + the :or and :as like:
(defn somefn
  [req1 req2 ;required params
{
  :keys [a b c d e] ;optional params
  :or {a 1 ;optional params with preset default values other than the
nil default
   ; b takes nil if not specified on call
   c 3 ; c is 3 when not specified on call
   d 0 ; d is 0 --//--
   ; e takes nil if not specified on call
   }
  :as mapOfParamsSpecifiedOnCall
  }]
  (println req1 req2 mapOfParamsSpecifiedOnCall a b c d e)
  )
;= (somefn 9 10 :b 2 :d 4)
;9 10 {:b 2, :d 4} 1 2 3 4 nil
;nil

this may be good for most people, but not for me. I've tried implementing
something for me but I have it only half way done (and I haven't looked at
in in a few months) it's here [1] but u won't like how it looks xD

meanwhile I realized what OP was saying with destructuring the arg vector.

 In case you really don't have the var itself but just its value, then
 unbound is a value, too, and you could check for it using

   (instance? clojure.lang.Var$Unbound *x*)
   ;= true

 nice one, thanks!

I was thinking just in case any of these clojure.lang.Var$Unbound change
in the future, maybe I'd do something like this:

=* (def uniqsym (gensym))*
#'jme3test1.x1/uniqsym

= *uniqsym*
G__1603

=* (defmacro defus [] `(def ~uniqsym))*
#'jme3test1.x1/defus

= *(defus)*
#'jme3test1.x1/G__1603

= *(class (eval uniqsym))*
clojure.lang.Var$Unbound

= *(def unbound-class (class (eval uniqsym)))*
#'jme3test1.x1/unbound-class

=* unbound-class*
clojure.lang.Var$Unbound

= *(def ^:dynamic *x*)*
#'jme3test1.x1/*x*

=* (instance? unbound-class *x*)*
true

=* (binding [*x* 1]
 (instance? unbound-class *x*)
 )*
false

=* (def ^:dynamic *x* 2)*
#'jme3test1.x1/*x*
=* (binding [*x* 1]
 (instance? unbound-class *x*)
 )*
false


instead of

   (not (bound? #'*x*))

  funny you should mention that!!! that is exactly what I meant by 'my
  fault'...I've come to realise that dynamic scope is almost evil, thus
  I go to great lengths to avoid it completely...in the rare cases where
  I do use it I always make sure it is bound to a init/default value :)

 I do exactly the opposite when I use dynamic vars, that is, I define no
 default value.  For example, there's a function foo that uses a dynamic
 var, and that must be bound and well-defined.  Therefore, I provide a
 macro to initially set it up, so that you write

   (with-bar (foo bla))

 and with-bar takes care of the proper initialization of that dynamic var
 (which is not even visible to the user).  When foo explodes because of
 the var being Unbound, then it's obvious that the function was called
 outside a with-bar macro and thus is a user error.  A default value

the thing is, that it may not always explode if not used with with-bar,
depending on the implementation of the function, as if when used in an
(cond (nil? thevar) ... )  or (str thevar)
If you ask me, I'd allow the var to be unbound and code everywhere for
cases where the var could be unbound - which there should be many ie. any
function; so I can understand why people would want to take the
easy/workaround way and set a default value instead.

= (defn decorate [input]
 (str prefix: input :suffix)
 )
#'jme3test1.x1/decorate
= (def ^:dynamic *y*)
#'jme3test1.x1/*y*

assume I forget to use with-bar here:
= (decorate *y*)
prefix:Unbound: #'jme3test1.x1/*y*:suffix
didn't explode
or here:
= (defn do-smth-with [input]
 (when (not (nil? input))
   (str doing something with  input))
 )
#'jme3test1.x1/do-smth-with
= (do-smth-with *y*)
doing something with Unbound: #'jme3test1.x1/*y*

= (do-smth-with *x*)
doing something with 2
= (decorate *x*)
prefix:2:suffix
= (do-smth-with nil)
nil

I guess what I was trying to say all along is that it's too easy to fall
into this by mistake because maybe most don't check for unbound and it may
not explode

would shadow such an error.

 A real-world example of this design are many database query libs, where
 you frequently have code like

   (with-db-connection (make-me-a-db-connection url)
 (select :from foo :where ...))

Re: Using a Java game engine in my project

seems to be working fine for me, are you not starting the repl from the

 4. Add the following to your project.clj file: :resource-paths [lib/*]
 5. Copy the lib directory from the jME3 binaries into your project
 directory

 http://confreaks.com/videos/77-mwrc2009-the-building-blocks-of-modularity

 Just as some of Glenford Myers' work in Composite/Structured Design fails
 to match some aspects of OO development, some of Meilir Page-Jones work in
 What every programmer should know about Object-Oriented Design fails to
 match some aspects of Clojure, FP, etc.

 For example, Clojure's handling of identity and value certainly speaks to
 the question of Connascence of Identity.  I'm not sure how much effect
 immutability has on connascence.  Certainly, using the data as the API
 (as Stuart Sierra recommends) differs markedly from OO best practices.

 However, the basic notion of identifying forms of coupling and thinking
 about their dangers (and benefits) is still very relevant.  If you want
 a good introduction to the topic, this is a good video to watch.

testing for nil may not be enough

How do you guys handle the cases when the var is unbound? I mean
specifically in the cases where you just test if the var is nil.

= (def a)
#'clojurewerkz.titanium.graph-test/a

= a
#Unbound Unbound: #'clojurewerkz.titanium.graph-test/a

= (nil? a)
false

= (bound? a)
ClassCastException clojure.lang.Var$Unbound cannot be cast to
clojure.lang.Var  clojure.core/bound?/fn--4837 (core.clj:4954)

= (bound? #'a)
false

ok imagine the following sample :))

= (defn decorate [input]
 (when (not (nil? input)) (str prefix: input :suffix)))
#'clojurewerkz.titanium.graph-test/decorate

= (decorate 1)
prefix:1:suffix

= (decorate a)
prefix:Unbound: #'clojurewerkz.titanium.graph-test/a:suffix

so... fix?
 but more importantly does anyone need to add checks for is-the-var-bound
in their code where they checked for nil ?

Re: testing for nil may not be enough

[AtKaaZ]

Seems like a good idea to have the root binding be nil. How would you make
it check for bound inside the function? do we need some kind of macro?


On Mon, Apr 29, 2013 at 7:23 PM, Gary Trakhman gary.trakh...@gmail.comwrote:

 Why not make the root binding nil?  If your decorate function is supposed
 to handle all vars, then they have to deal with the unbound case as that's
 part of the contract of vars.

 If it's a generic thing, then maybe make a multimethod or protocol for it.

Re: testing for nil may not be enough

[AtKaaZ]

I'm thinking of a hacky way of doing it...
(def a nil)
(def b)

= (defn x [in]
 (when (not (nil? in)) (.v in)))
#'clojurewerkz.titanium.graph-test/x

= (x b)
#'clojurewerkz.titanium.graph-test/b

= (x a)
nil

Re: testing for nil may not be enough

oh right, you mean that I should pass the var like (decorate #'a), I didn't
get that when I first read it. But suppose I'm just passing the
whatever-that-is (value?) like (decorate a) do I need to use a macro inside

Re: testing for nil may not be enough

[AtKaaZ]

thank you, I'll look into protocols


On Mon, Apr 29, 2013 at 7:54 PM, Gary Trakhman gary.trakh...@gmail.comwrote:

 You would only need a macro if you want to pass in 'a' and mean #'a.
  Syntactic abstraction.  Like I said, I'd make the implementation
 polymorphic on that value via a protocol so you're not special-casing it
 within the function itself.  Protocols are open for extension so someone
 else could come along and provide an implementation for something you
 haven't thought of doing.

Re: Using a Java game engine in my project

[AtKaaZ]

Hi, I've been planning on trying the instructions/code from [1] with regard
to jme3 and clojure but I haven't got there yet. Does that help you ?

There's also this project [2] which uses jme3 in clojure. The last time I
tried it I was able to get a window and a 3D scene.

 Hello! I have a problem, I will try to explain.. I want to write a game
 with Clojure and JMonkeyEngine (http://jmonkeyengine.com/). So I take
 their latest nightie set of jars (http://jmonkeyengine.com/nightly/)
 and what? I can't make use of them in my CCW/Leiningen project no
 matter how hard I try. So ok, I have found some examples where people get
 them in the lib folder and it works, or where they recommend pushing them
 to the local maven repo... but they do not tell how they do it, or they
 show it for some very simple cases. Sure, there is a lot of instructions
 like use mvn install:install-file a-lot-of-stuff-goes-here or lein
 localrepo install less-stuff-but-hey... so do I have to do it for all
 the 30 (thirty) jar files? Considering too, that I have to invent an
 artifactId for every one of them, invent a version number, type all
 that in manually. And that is not my library, I do not want to invent that.
 And even, if I do that, then, how do I specify that all them are
 interdependant (are parts of one thing) and have to be always drawn in
 together? I will have to specify the 30 dependencies in my project.clj each
 time? Well, and even if I do, then I will still have that pain with
 manually copying all that stuff on each new machine where I work, picking
 it from the local maven repo and putting it to another maven repo. And
 if I want to push it to Clojars, I have do that for each one manually too,
 typing in commands in the Windows cmd and taking care for inventing version
 numbers?... oh, and maybe I could go about specifying dependency clauses
 in a pom? pinch me am I dreaming a nightmare? :)

 I have tried to do something along these lines... spent about 15 hours in
 general and got almost nothing but headache and eyesore... and a feeling of
 being extremily stupid for not being able to plug a few jars into a jvm
 program (isn't java all just about putting jars together? :) ). I am a
 Clojure newb and maybe I am missing somewhat essential.. but in Scala, with
 or without SBT, using Scala IDE for Eclipse, I got everything up and
 running in about 15 minutes.

 Please, could anyone give me a clear explanation or better, a full example
 of plugging in the JME3 into a Clojure project? Shouldn't it be simple?
 Thank you in advance, the situation is really disappointing for me :(

 Here's an example application to get you going:

 Please, could anyone give me a clear explanation or better, a full

Re: Using a Java game engine in my project

[AtKaaZ]

that seems unsafe.

I'd rather use a nightly zip or what I am currently using, jme3 engine as
project in eclipse and when needed ant build it and have my project always
refer to the lib folder in the dist ie. I've these 2 lines in my project:

  :bootclasspath false;false is needed here for JME3 specified in
:resource-paths below; else it will fail with ClassNotFoundException
com.jme3.app.SimpleApplication  java.net.URLClassLoader$1.run
(URLClassLoader.java:366)

  :resource-paths [resources, ../jme3_engine/dist/lib/*] ;needs eclipse
project present: jme3_engine from trunk/engine ie.
https://code.google.com/p/jmonkeyengine/source/browse/#svn%2Ftrunk%2Fengine
and make sure you ant build it once to create and populate dist/lib/ folder

works fine for me in eclipse/ccw

btw, maybe you(Jonathan) and James could focus your efforts and release one
clojure jme3 library instead of two (eventually), or not...  just a
thought. It would seem like a waste if there will be two. (like hermes and
titanium people are focusing only on titanium now)

It'd be really cool to have a clojure 3D lib based on jme3

 The biggest problem with it right now is that it contains all test models

recur doesn't complain when autoboxing fails?

[AtKaaZ]

= (defn abc [] 3)
#'ants/abc

= (loop [a 1]
 (when (= 1 a) (recur (abc
NO_SOURCE_FILE:2 recur arg for primitive local: a is not matching
primitive, had: Object, needed: long
Auto-boxing loop arg: a
nil

= (loop [a 1]
 (when (= 1 a) (recur (long (abc)
nil

= (loop [a 1]
 (when (= 1 a) (recur *(var defn)*)))
NO_SOURCE_FILE:2 recur arg for primitive local: a is not matching
primitive, had: Object, needed: long
Auto-boxing loop arg: a
nil

How was that boxed into long? :O
since this wouldn't work:

= (loop [a 1]
 (when (= 1 a) (recur (long (var defn)
ClassCastException clojure.lang.Var cannot be cast to java.lang.Number
clojure.lang.RT.longCast (RT.java:1151)

= (long (var defn))
ClassCastException clojure.lang.Var cannot be cast to java.lang.Number
clojure.lang.RT.longCast (RT.java:1151)


= (loop [a 1]
 (cond (not (= 1 a))
   a
   :else
   (recur (var defn
NO_SOURCE_FILE:5 recur arg for primitive local: a is not matching
primitive, had: Object, needed: long
Auto-boxing loop arg: a
*#'clojure.core/defn*

Shouldn't it err saying that it can't autobox into long? or am I missing
the meaning here? it does say that it had Object and it needed long, does
that autoboxing make it Long or long? apparently it just leaves it as
is:*#'clojure.core/defn
*

Any thoughts on this?

= (loop [a 1]
 (cond (not (= 1 a))
   a
   :else
   (recur (abc
NO_SOURCE_FILE:5 recur arg for primitive local: a is not matching
primitive, had: Object, needed: long
Auto-boxing loop arg: a
3

= (loop [a 1]
 (cond (not (= 1 a))
   a
   :else
   (recur (long (abc)
3

this makes sense.

Re: recur doesn't complain when autoboxing fails?

[AtKaaZ]

Thank you very much, I see it now.
1. boxing means from primitive to object; unboxing is from object to
primitive (I disregarded this for some reason)
2. it does say the loop arg not the recur arg: Auto-boxing loop arg: a

 The compiler isn't telling you it will need to box your recur arg into a
 long, but that it will be boxing your initial loop arg into an Object.
 Think of the message as Maybe you intended `a` to be a primitive local,
 but since you passed `recur` a who-knows-what, it won't be.

that's true but I thought you meant in general

something that can replace that (var y) with something that actually gets

Re: printing and reading functions

[AtKaaZ]

ok you're right, it's impossible to get the var since those x and y are
already resolved to the function, and multiple vars could point to the same
function anyway.
= (let [x assoc
 y x]
 (get-lexical-env)
 )
{x #core$assoc clojure.core$assoc@35fcd90c, y #core$assoc
clojure.core$assoc@35fcd90c}

for consistency, ignore the following:
;the following is inspired from
http://blog.jayfields.com/2011/02/clojure-and.html
(defmacro get-lexical-env []

= (let [a 1 b (+ 1 2)]
 (let [c (do \a\ \b\)]
   (q/get-lexical-env)
   )
 )
{a 1, b 3, c \b\}

  (let [envkeys (keys env)]
`(zipmap (quote ~envkeys) (list ~@envkeys))
)
  )

(defmacro show-lexical-env []
  `(clojure.pprint/pprint (get-lexical-env))
  )
