Use destructing:

(defn f [required & {:keys [foo bar] :or {foo :default}}]
  [required foo bar])

(f 3 :bar 1 :foo 2) ;=> [3 2 1]
(f 3 :bar 1)  ;=> [3 :default 1]

Re: Best practices for named arguments

[Meikel Brandmeyer (kotarak)]

Hi,

you can use destructuring to provide defaults. And you can easily curry in 
options when passing things through.

(defn general-descend
  [xy ys &
   {:keys [gradient-fn cost-fn yield-fn alpha iterations thetas]
:or   {cost-fncost
   yield-fn   println
   alpha  0.01
   iterations 1000
   thetas (matrix 0 (second (dim xs)) 1)}}]
  ...)

(defn special-descend
  [xs ys & options]
  (apply general-descend xs ys :cost-fn cost options))

Kind regards
Meikel

Re: Best practices for named arguments

[David Jacobs]

I'm not sure you read the whole question. I want to know how to delegate 
optional arguments to other functions with the same method signatures.

Re: Best practices for named arguments

Ah I see, I didn't realize I could apply the general-descend algorithm to 
both atoms and arrays to get a flattened list. Thanks!

Re: If a protocol creates a Java interface under the covers...

[Korny Sietsma]

You keep talking about performance.  I'm a long way from being a clojure
expert, but one thing I *do* know is that premature optimization is the
root of many many evils.

May I suggest you first get your app working, in a clean understandable
fashion, ideally with some solid unit tests. Then, and only then, profile
it, work out if it performs adequately, and optimise the parts that need it?

(apologies if this is the approach you are already taking - it's bit clear
from your posts if that is the case)

I think the best is to use maps. It is rarly a good idea to have too many

Re: If a protocol creates a Java interface under the covers...

[Jim - FooBar();]

Performace was an issue right from the start for this project, that's 
why I went down the protocol/record path instead of 
multi-methods...surely, this is a decision to be made in the beginning, 
isn't it?


I did take into account all the comments so far...my world is now fully 
immutable, reset! is out of 'move', and I've got far less macros 
(replaced them with return-type-hinted fns)...


Also I only starting optimizing (type-hinting) when the namespace 
finished...ok, I did have some design error as it turned out, but it was 
only when I had no more code to write in that namespace that I started 
type-hinting...


I appreciate your concerns though... :-)

No, my variant also returns nil for "e is not in coll", but the
difference is that my version works for nil and false values:

  (in? [nil false] nil)   => true
  (in? [nil false] false) => true

whereas your version with the hash-set returns nil and false in those
cases.

clojure-csv library write-csv examples

I would appreciate getting a pointer to some clojure-csv library write-csv 
examples.

Re: clojure-csv library write-csv examples

[octopusgrabbus]

The reason why I asked this question is this code looks like it's using 
another csv library, so I'm confused.

(require '[clojure.data.csv :as csv]
 '[clojure.java.io :as io])

(with-open [in-file (io/reader "in-file.csv")]
  (doall
(csv/read-csv in-file)))

(with-open [out-file (io/writer "out-file.csv")]
  (csv/write-csv out-file
 [["abc" "def"]
  ["ghi" "jkl"]]))

You could just do (vec (mc/find-maps "events")).

Also, using def creates a top-level var. You probably wanted (let [items

Why do you want to return a vector? Do you absolutely need some of the
features that only vectors can provide (indexing, etc.)?

Nevertheless, the code that you wrote is not correct in the Clojure
world. `def` creates a top-level var and that should be only used to
store `global` bindings; `def` is not a way to declare variables.

You should write the code like this instead -

(init) ;; outside, preferably called only once during app initialisation

(defn get-events-hlpr []
  "Retrieves events from MongoDB."
  (vec (mc/find-maps "events")))

You are right, Tassilo, I just copied the original code to a scratch
buffer and edited it without looking at the doc-string.

This is how it should be done, really -

(defn get-events-hlpr
  "Retrieves events from MongoDB."
  []
  (vec (map #(dissoc :_id %) (mc/find-maps "events" ;; remove the
:_id as well

It's not really a good idea to AOT your code and then directly try to
use it from java. The generated java bytecode isn't guaranteed to be
stable across versions of clojure, and you're depending on
implementation details.

One way to use your clojure code from java is through RT. An example
would be the accepted answer here:
http://stackoverflow.com/questions/2181774/calling-clojure-from-java

Another tack you can take is to use gen-class to create a "real" java
class from clojure and use that as an entry point to your clojure
code.

ClojureScript Analyzer Decoupled

[David Nolen]

Thanks to Raphael Amiard's hard work the ClojureScript analyzer is now
decoupled:

http://github.com/clojure/clojurescript/commit/9ad79e1c9b87c862ccb7ad6aad37d90414123c76

This is a big step towards making the ClojureScript compiler infrastructure
pluggable. There's a couple of JS things to clean up in the backend and
we're looking to remove any JS specific stuff from cljs.core so that
alternate backends can compile the standard library with no fiddling.

Fun times ahead!

Re: ClojureScript Analyzer Decoupled

[Timothy Baldridge]

I've been working on a platform-agnostic version of this over here:
https://github.com/halgari/universal-clojure/blob/master/src/universal_clojure/core.clj

But I'd rather collaborate with ClojureScript. Are there any ongoing
efforts to make this cross platform? The current analyzer contains
quite a few java calls. For instance, .contains, and .indexOf. Is
Raphael working on this, or can I take up that torch and implement
these in pure Clojure?

After that, I'd like to rip apart core.cljs and make it also platform
agnostic. My idea is to standardize the native calls under a pseudo
namespace called "native". For instance:

(defn alength [array]
  (native/alength array))

(defn aget [array idx default]
  (if (and (>= idx 0) (< idx (alength array))
  (native/aget array idx))
  default))

All a new platform needs to do is have their compiler interpret
native/alength as the platform specific call (.Length in CLR, len() in
Python, etc.), and the above code is suddenly 100% cross platform.
>From there, porting to a new platform is no longer "translate
core.cljs", but instead, "implement these 20 functions from native/".

I'm really wanting to collaborate on this, since I plan on basing
future versions of Clojure-Py completely off this code base. Any
suggestions on how to go about this? I don't want to re-write anyone
else's code, but I'm also kind of tired of waiting around for someone
to hand me this on a silver platter :-).

A bootstrappable compiler infrastructure is not a goal at this point as far
as I know. Certainly open to patches that make the analyzer easier to
compile elsewhere.

If somebody wants to make the compiler bootstrappable they need to outline
some kind of plan that allows ClojureScript (JS) development to continue
with minimal disruption. There are many decisions (non-reified vars and
namespaces, compiler macros, etc.) which make a lot of sense for the
JavaScript target that may not make sense for other targets.

Not necessary IMO we have compiler macros - each backend brings their own
compiler macros.

Make a Confluence page outlining what you think needs to be done so there

I really don't like the RT way (very clumsy), so I want to avoid it if 
possible. My .jar file will include Clojure itself in it, so compatibility 
with different version of Clojure is not a problem for me. 
But is there any other pitfalls using AOT?

 My understanding is "defrecord" actually generate a real named java class. 
And I can use it in Eclipse project so it seems that is the case.

BTW: my issue is solved by using some kind of annotation defined by the 
target Java framework. However, I could have been in a dead end if there is 
no such annotation and the classloader is messed up. So just as someone 
says "things are never as simple as it seems".

Classpath set by lein swank or clojure-jack-in

[Dave Kincaid]

One of the things that really been holding me back from moving ahead with 
Clojure is the difficulty I have running code that I'm writing using a 
repl. I generally use Emacs to code Clojure and I really don't understand 
how the classpath gets set when I use either "lein swank + slime-connect" 
or "clojure-jack-in". I can't seem to get it to find either any 
dependencies that I've included in the project.clj or any of my own code 
without a lot of hit and miss trial and error. Eventually I can usually get 
it to work by doing all kind of things like compiling the .clj file, 
launching lein swank from different directories, etc. Is there a good 
document that I could read to understand how I should be doing this. It's 
so frustrating that I don't even want to try writing Clojure code most of 
the time eventhough I'm loving the language.

Thanks,

Dave

Re: Classpath set by lein swank or clojure-jack-in

[Peter Buckley]

Once I got lein swank and slime-connect working in emacs, I essentially stopped 
using the repl directly. The real magic and beauty of writing clojure in emacs 
is that I can write a fn, then C-x C-e to evaluate it right there in the file. 
I can evaluate inner forms, test every line of the file to confirm it works, 
experiment, etc, and the code is all saved in the file. 

I don't want to write anything *other* than clojure because it's such a 
beautiful and effective experience.

Re: Classpath set by lein swank or clojure-jack-in

[Dave Kincaid]

I'm with you, Peter. The problem is I can't get lein swank and 
slime-connect working in a consistent way. It starts up fine but can't find 
any dependencies that I try to (use ...) or even any of the code in my .clj 
files that I try to access. I just can't understand what it's using as a 
classpath when it's launched. When I do stumble on the right combination of 
directory, lein swank and emacs buffer it is awesome!

Re: Classpath set by lein swank or clojure-jack-in

[Moritz Ulrich]

That's strange. You usually just run lein swank in the folder with you
project.clj. Nothing to do wrong there.

Can you show the project.clj and the directory structure of a non-working
project?

Re: Classpath set by lein swank or clojure-jack-in

[Dave Kincaid]

Sure can. Here is the project.clj:

(defproject swank-test "0.1"
  :source-path "src/main/clj"
  :test-path "test/clj"
  :java-source-path "src/main/java"
  :javac-options {:debug "true" :fork "true"}
  :resources-path "src/main/resources"
  :dependencies [[org.clojure/clojure "1.4.0"]
 [cascalog "1.9.0"]
 [org.apache.hadoop/hadoop-core "0.20.2" :exclusions 
[hsqldb/hsqldb]]])

I have a file named generator.clj in src/main/clj. When I do a "lein swank" 
from the directory that project.clj is in then run slime-connect in Emacs 
with the generator.clj file open. Then I try to do (use 'generator) and get

Could not locate generator__init.class or generator.clj on classpath: 
  [Thrown class java.io.FileNotFoundException]


what am I doing wrong?

How to do aynchrounous producer/consumer

[Warren Lynn]

What I want to do is something I probably have done dozens of times in C++: 
two threads, one thread putting items in a queue, another taking it out 
(FIFO). How to do it in Clojure? I am at a loss. I thought about a few 
options:

1. "watches", but it cannot change the queue itself (can only watch). plus, 
I am not sure watch function will run in another thread
2. "agent", but how to notify the consumer thread when there is new item? 
How to block the consumer thread when there is no items in the queue?
3.  Ping-pong promises: so the producer delivers a promise to the consumer, 
and the consumer immediately deliver another promise to the producer to 
acknowledge the receipt so the producer can move on. But that will prevent 
the producer to put the next item into the queue before the consumer finish 
its processing, so not exactly concurrent.

I cannot believe I am the first one to encounter this. Can anyone suggest 
some idiomatic solution for the above? Thank you.

Re: Classpath set by lein swank or clojure-jack-in

[Sean Corfield]

Have you tried visiting the project.clj file in Emacs and then doing
M-x clojure-jack-in ? That should start lein swank in the project
directory and pull in all the dependencies as expected.

(you should start lein swank in the project root directory -
containing project.clj - not in a subdirectory)

Or in Clojure 1.4.0 and later:

(defn get-events-hlpr
 "Retrieves events from MongoDB."
 []
 (mapv #(dissoc :_id %) (mc/find-maps "events"))) ;; remove the :_id as well

mapv, filterv and reduce-kv are new in 1.4.0.

Re: Classpath set by lein swank or clojure-jack-in

[Peter Buckley]

Probably over-cautious because of my ignorance, but I don't know if I would 
name the project "swank-test" as I haven't paid too close attention to what 
seems a slightly confusing rule about "dashes in namespaces and underscores in 
filenames" - also swank-test might be some sort of existing namespace that 
secretly gets loaded and oddly conflicts. 

I also haven't done much with directory structure under the src/ 
folder - do you have the same problems with a project that only has one file, 
or only files in that folder?

Like I said this is mostly based on my ignorance, and getting a handle on the 
namespacing is probably a good idea, but I've never had an issue with my small 
projects with flat/default directory structures. Might workaround it for you in 
the short term.

Re: Classpath set by lein swank or clojure-jack-in

Thanks I'll give those things a try. swank-test was just a small project I 
threw together as an example for this post. The directory structure is the 
same as my big project though. I'll play around with your suggestions and 
see if I can find a pattern to when it works and when it doesn't.

Thanks,

Phil has streamlined

all the actual documentation is in the clojure-mode repo (and the
swank-clojure repo - for SLIME/Swank setup). That means anyone can

I don't know the first thing about logic programming so can't say whether 
something like this would be practical to implement or not - but boy what a 
neat idea!

I'm constantly needing to restructure bits of data and while it's not 
exactly tough to do in Clojure, something like this would certainly be 
welcome.

I hope you can figure out a way of making this work. I'll try take a look 
again once you've got some examples up to see if there's anything I could
