Need to render some entities moving across a grid
I'm implementing a program D. Hofstadter describes in *Fluid Concepts: * https://github.com/vemv/jumbo/* *Even in the original text, concurrency/parallelism is a crucial part of the domain so Clojure is super well-suited. While visualising the carried-in process is not a goal of the project, providing a rendering of the 'entities' of the modelled world would help a lot explaining my program to others (which I have to). The thing is - I haven't ever done significant graphics programming - I don't know e.g. what libraries to use, how to create smooth movements, keep the code high-level... and sadly I don't have a lot of time in my hands. Would anyone knowledgeable in the matter mind coding a quick-and-dirty solution for me? I could buy you a couple books in exchange hahaha. You'd have exactly one week, and I of course would provide all needed information/feedback. Feel free to reply here or contact me at vemv [at] vemv [dot] net.

Any suggestions for configuration solution in Clojure or Java world?
After suffer xml or properties configuration for long time, I'm looking for a new configuration solution for Clojure or Java. I hope below features, priority from high to low: 1. readable format and easy to write. XML is the opposite example, which is not easy to edit and not readable. I like Json or YAML, especially JSON. 2. support difference environments. The difficult things I have are distributes difference package for difference environments (dev, gamma or online). My practice are write difference set of configuration files for each environment, for example we have database-dev.properties and database-online.properties for respectively dev and online environment, then pass a argument to startup script to control which file to load. it's just work, but the problem are there are only small part of config is difference between and dev and online, but I have to rewrite and maintain all config in two files. 3. easy to organize if there are a lot of configuration files. It's very common that there are many configurations distributes in difference files. Sometimes one file's configuration need override another. we need a solution to management them. 4. we can very easy override configuration by CLI argument or system environment variable. Sometimes we have to temporarily change configuration for debug or troubleshooting purpose. I hope we can easy to override configuration not change the configuration files. For the #1, the HOCON ( https://github.com/typesafehub/config ) is the best config syntax what I have ever seen. But I didn't find out a solution which can satisfy rest of other features.

Re: Any suggestions for configuration solution in Clojure or Java world?
We built our own tool using zookeeper. We need to manage clusters of nodes, clearly property files were not scalable enough to be of any help here. All the configuration values are written using Clojure expressions, not just EDN like stuff, we do eval code loaded in the configuration to provide extensibility. We wrote a DSL to maintain the configuration. You can then implement versioning, rollbacks, whatever features you may need. When a node boots, it needs a 4 lines property file to find its root in the cluster configuration. Any process on the node pulls it's configuration from this root.

type-hints positioning convention?

Re: Need to render some entities moving across a grid
For something quick and dirty, have you taken a look at quil? It's pretty
easy to get started.

While visualising the carried-in process is not a goal of the project,
providing a rendering of the 'entities' of the modelled world would help a
lot explaining my program to others (which I have to).
The thing is - I haven't ever done significant graphics programming - I
don't know e.g. what libraries to use, how to create smooth movements, keep
the code high-level... and sadly I don't have a lot of time in my hands.
Would anyone knowledgeable in the matter mind coding a quick-and-dirty
solution for me? I could buy you a couple books in exchange hahaha. You'd
have exactly one week, and I of course would provide all needed
information/feedback.

Re: Any suggestions for configuration solution in Clojure or Java world?
I have wrapped up the Typesafe Config pieces, that can read EDN and HOCON in: https://github.com/ohpauleez/confil The project should be considered pretty alpha and the general interface may change. I also have plans to make two supplemental project: confil-literals (that bring along reader literals for various config entries), and confil-archaius ( https://github.com/Netflix/archaius ).

I hope below features, priority from high to low: 1. readable format and easy to write. XML is the opposite example, which is not easy to edit and not readable. I like Json or YAML, especially JSON. 2. support difference environments. The difficult things I have are distributes difference package for difference environments (dev, gamma or online). My practice are write difference set of configuration files for each environment, for example we have database-dev.properties and database-online.properties for respectively dev and online environment, then pass a argument to startup script to control which file to load. it's just work, but the problem are there are only small part of config is difference between and dev and online, but I have to rewrite and maintain all config in two files. 3. easy to organize if there are a lot of configuration files. It's very common that there are many configurations distributes in difference files. Sometimes one file's configuration need override another. we need a solution to management them. 4. we can very easy override configuration by CLI argument or system environment variable. Sometimes we have to temporarily change configuration for debug or troubleshooting purpose. I hope we can easy to override configuration not change the configuration files. For the #1, the HOCON ( https://github.com/typesafehub/config ) is the best config syntax what I have ever seen. But I didn't find out a solution which can satisfy rest of other features.

'foldcat' slower than 'mapv' even for 10,000 elements
Hi again, I'm finding that (r/foldcat (r/map f coll)) is consistently slower than a simple mapv, even for a collection of 10,000 elements and more! The fn I'm mapping is a stemming algorithm, not too heavyweight but not too lightweight either... is anyone else finding this strange or am I missing something?

Re: Clojure in production
Hi Plinio, we released today in production a clj/cljs application which implements an animated/interactive bubble chart on client side by getting tha data (in edn format) from the the server. The client has been implemented by using clojurescript and the following main libs: - domina - c2 - d3 The server has been implemented by using clojure and the following libs: - compojure - korma - necessary-evil - timbre - clj-logging-config The edn format is exchanged between the server and client by using shoreleave-remote-ring and shoreleave-remote. We're very happy with both clojure and clojurescript. In a couple of week we're going to release the bubble-chart component on github.

Feedback request: Spec for meta testing-lib
The goal is to have an extensible, simple core for a testing lib, where all other Clojure testing libs can be rewritten as extensions to it. A common motivation is that people want to mix and match aspects/features of different testing lib. But really, each person wants this for different reasons. What we have in common though is wanting it to exist. Here's the spec: https://github.com/evanescence/test2/blob/master/SPEC.md The current incarnation is the result of several weeks of collaborative brainstorming and obsessive tweaking and refining. We think it can currently cover about 99% of testing use-cases as-is. So, I'd like to present it to the wider community for discussion. Note: there's a debate going on in IRC over nouns vs verbs, i.e. whether Runner and Reporter should be Run and Report, or Run-fn and Report-fn, or something else. But I'm hoping we can put off that topic until after the more fundamental aspects of the spec are discussed. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

They don't seem to help resolve reflection calls.

I don't see where before-the-arglist is useful outside of primitive fns.

Hi all,
It seems to me that return type-hints can go either right after
defn, or after the doc-string. I generally, put the return
type-hints right before the argument vector and it seems to get
rid of reflection. However, I just had a look at
core.contrib.strutils2 and the author(s) put the type hint right
after 'defn' (before the var about to be defined) and again it
gets rid of reflection! Which one is it? both are acceptable?
thanks in advance,
Jim

Yes, it did. That's interesting. I have no idea where the .length method is
being inferred from in the last example.

OK now I'm confused! If you are using an unnamed fn form there is only
one place to put the return type-hin,t and that is between the 'fn' and
the '[...]'

else can we put it?

Re: type-hints positioning convention?
Typehints for functions are only useful on vars. There is no code anywhere,
as far as I know, that looks at the metadata attached to anonymous
functions.

(require '[clojure.tools.analyzer :refer [ast]])
; this creates a double-emitting fn
(ast (fn (^double [^double a] a)))
; =
;{:op :fn-expr,
; ...
; :methods
; ({:op :fn-method,
; ...
; :arg-types (#Type Ljava/lang/Object;),
; :return-type #Type D}), ;double return type here
; ...
; :tag nil} ; no tag
; this creates a regular old fn
(ast (fn (^String [a] 1)))
; =
;{:op :fn-expr,
; ...
; ({:op :fn-method,
; ...
; :arg-types (#Type Ljava/lang/Object;),
; :return-type #Type Ljava/lang/Object;}), ;object return type
; ...
; :tag nil} ; no tag
; this creates a String-hinted fn
(ast ^String (fn a [a] 1))
;{:op :meta,
; ...
; :expr
; {:op :fn-expr,
; ...
; :methods
; ({:op :fn-method,
;:arg-types (#Type Ljava/lang/Object;),
;:return-type #Type Ljava/lang/Object;}),
; ...
; :tag String}}
I don't see where before-the-arglist is useful outside of primitive
fns.
Thanks,

Hi all,
It seems to me that return type-hints can go either right after
defn, or after the doc-string. I generally, put the return type-hints
right before the argument vector and it seems to get rid of reflection.
However, I just had a look at core.contrib.strutils2 and the author(s)
put
the type hint right after 'defn' (before the var about to be defined) and
again it gets rid of reflection! Which one is it? both are acceptable?
thanks in advance,
Jim

Re: Any suggestions for configuration solution in Clojure or Java world?
I glanced at this a while back - does carica support java -jar myuberjar.jar config.clj type invocation, or is it strictly compile the config in a la bundle into the class path? I generally ship the same uberjar around for prod/dev/etc. along with a per-environment config.clj file, and that seems to work great.

Graph API
Hello, I want to create a graph API similar to what core.matrix is for matrices. I have created some protocols which every graph implementation has to satisfy and a prototype implementation. Now I want your feedback on these protocols. Which functions do you want to see which aren't there? Which functions should be changed? Are there problems with the general design? Have you any other feedback? Here are the protocol definitions: (defprotocol PGraph Minimal functionality of a graph. (directed? [g] Returns true if the graph is directed and false if the graph is undirected. If it is undirected, all functions taking two nodes must be commutative with regard to these nodes.) (nodes [g] Returns a set or sequence of all nodes of the graph. May not contain duplicates.) (has-edge? [g n1 n2] Returns true if the graph g has an edge from node n1 to node n2.) (direct-successors [g n] Returns a set or sequence of all nodes n2 for which (has-edge? g n n2) returns true. May not contain duplicates.)) (defprotocol PPredecessorGraph Optional functionality of a graph which can give a list of all direct predecessors of a node. (direct-predecessors [g n] Returns a set or sequence of all nodes n2 for which (has-edge? g n2 n) returns true. May not contain duplicates.)) (defprotocol PEditableGraph Minimal functionality of an editable graph. (mutable? [g] Returns true if the graph is mutated in place. If true is returned, the other functions change the graph passed as the first argument and return the same graph object. If false is returned, the functions return a new graph and the old graph is unchaged.) (add-node [g n] Adds the node n to the graph g. If it already contained n, the graph will not be changed.) (remove-node [g n] Removes the node n from the graph g. If it did not contain n, the graph will not be changed.) (add-edge [g n1 n2] Adds an edge from node n1 to node n2 to the graph g. If one or both of the nodes is not present it will be added to the graph. If the edge was already present, the graph will not be changed.) (remove-edge [g n1 n2] Removes the edge from node n1 to the node n2 from the graph g. If it did not contain the edge, the graph will not be changed.)) (defprotocol PWeightedGraph Functionality of a graph whose edges can be weighted. (edge-weight [g n1 n2] Returns the weight of the edge from node n1 to node n2.)) (defprotocol PEditableWeightedGraph Functionality of a weighted graph whose weights can be changed. (update-edge-weight [g n1 n2 f] Updates the weight of the edge from node n1 to node n2, where f is a function taking the old value and returning the new one. If the graph did not contain the edge, it will be created.)) (defprotocol PNodeDataGraph Functionality of a graph which stores data with its nodes. (node-data [g n] Returns the data of the node n.)) (defprotocol PEditableNodeDataGraph Functionality of a graph which stores editable data with its nodes.

Medical Diagnostic (Expert System)
Hello everyone, I'm a beginner programmer of Clojure language and I have a projet where i need to translate a discusion between a patient and a system to an expert system in clojure.So first here are the basis rules : Rule1 : If hedeach then prescribe analgesichttp://traduction.sensagent.com/analgesic/en-en/ . Rule 2 : if hedeach and sore throat and cough then flu. Rule 3 : if exhausion and hedeach then fever (priority 10). Rule 4 : if hedeach and sore throat then angina (priority 90). Rule 5 : if exhausion then stress (priority 90). And here is the discusion betwwen the patient and the system : Patient : I have a hedeach. System : I suggeste to take an analgesic.Do you have :No, sore throat ? Patien : Yes. System : Do you have a cough ? Patient : No, why ? System : if you have a hedeach and sore throat and cough, I would conclude that you have a flu.It seems like you do not have a flu.Do you feel exhausion recently? Patient : Yes. System : It seems you have an angina or a stress. thank you for your help :) -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Graph API
I think that there's already a project working on this called Loom. The furthest-developed fork is here: https://github.com/aysylu/loom which appears to have protocols for graphs, bindings to Titanium (the Clojurewerkz graph DB library), visualization support, and implementations of several algorithms.

Re: Graph API
Take a look at Tinkerpop's blueprints for a well tested Java API and Archimedes for simple graph operations in Clojure. http://www.tinkerpop.com/ https://github.com/clojurewerkz/archimedes As far as the suggested protocols go, I would suggest doing something useful with them before opening it up to the community for comments. There's not much there to discuss in terms of merits or anything else. -Zack On Monday, June 17, 2013 4:14:34 PM UTC-4, dgrnbrg wrote: I think that there's already a project working on this called Loom.

Unquoting 'camel-case-method-name' is going to try and replace the symbol with it's value during compile-time in the context of the macro itself. also, reify isn't going to work if you need a named class to actually wire up your servlet, for example with a web.xml.

Performance optimizations dealing with java collections
I'm working on a small clojure program which pulls data from a custom memory-backed data store via a java api. When looking at performance, there is a hotspot at the point of interaction with this API. One of the fields of each record being exported contains a list of lists of strings (ListListString) with about 60-150 items in the outer list and 5 items in the inner list. The problem is that at the point of assimilating this java data type into clojure, there are a couple calls taking ~30-40% of the execution time. Here are the senarios; I'm just starting to get familiar with clojure internals, so forgive obvious blunders in this. Processing it as: (map parse-field (.getAllFields datastore)) with parse-field defined like: (defn parse-field [^List field] ...) or (if I change the API call) (defn parse-field [^[Ljava.lang.String; field] ...) it calls clojure.lang.RestFn.invoke() which wants to build an ArraySeq, which calls java.lang.Class.getComponentType, which is a killer (20 of 50 seconds on 500 records). With parse-field using destructuring, on either the List or String array, clojure.lang.RT.nthFrom() is invoked, which calls java.lang.Class.isArray (https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/RT.java#L773), which is a killer as well. So I inlined parse-field and used loop/recur (instead of map) and .get on the list to get the next item, but this still results in the RestFn.invoke()-ArraysSeq-Class.getComponentType path. This is related to http://dev.clojure.org/jira/browse/CLJ-1200, although called via a different path. Does anyone have any ideas on how I could avoid these calls?

Re: First day with Macros
I can't speak to the issues that Gary raised, but I can help you with your macro. (defmacro servlet [servlet-name meths] `(reify Servlet ~@(for [meth meths] (let [[method-name args body] meth method-name (hyphenated-camel-case method-name)] `(~method-name ~args ~@body) The key here is to keep track of when things are run. The `for` must be run at compile time in order to generate the code we want, so we have to escape it with ~@. The code that the `for` creates (in the form of a list) must then be (quasi-)quoted again by the backtick. Macros certainly take some getting used to.

Re: Heroku Clojure scheduled tasks versus worker threads
Heroku cron jobs and workers are prorated like dynos. They run in their own processes. So does booting into heroku bash or heroku console. Workers generally consume a queue. I'm not sure what you mean by worker thread though. Workers don't run in a thread, and you can launch plain old threads whenever you want to in your Clojure code. Heroku isn't going to bill you for threads. Perhaps I've misunderstood. On Monday, June 17, 2013 7:27:21 PM UTC-5, Jonathon McKitrick wrote: How would you sum up the differences?

Re: Graph API
Loom was indeed working on this, and it's a very nice library. One thing that I particularly liked about Justin's design, was the ability to run a graph algorithm without worrying about conforming to a particular graph representation. See for example the bread first search function, here: https://github.com/jkk/loom/blob/master/src/loom/alg_generic.clj#L110 All the bfs function requires is a neighbors function and and a start vertex. Simple and easy to use. Justin had said that he won't be actively developing loom for the forseeable future; I was hoping to develop it further, but I only got as far as implementing a max flow algorithm before the rest of my life got in the way of my plans. I know that Aysylu was doing a fair amount of work on loom, so I'd guess that her repo is the most advanced one. Stephen: I think the set of protocols above is good, better than Loom's in fact; notably, the decision to make direct-predecessors optional is the correct one, and a lot of graph libraries get that wrong.

Multiple args: opts map vs inline arguments
Hey folks, What'c considered more idiomatic when having multiple, optional arguments? (defn foo1 [a b args] (let [opts (apply hash-map args] ...)) or (defn foo2 [a b opts] ...)

Re: Multiple args: opts map vs inline arguments
According, to the library coding standards, the first is better:
(release-sharks 2 :laser-beams true); good
(release-sharks 2 {:laser-beams true}) ; bad

Re: In what OS do you code?
OS X on the working machine, Ubuntu on the servers. For my project it makes little difference, especially with *brew* on the mac. Currently moving from vi to emacs.
