Re: [ClojureScript] Single Output File for Multiple Pages or Multiple Output Files?
Hi Zhao, sorry to be so late, but I did not see your question until now. I was investigating a similar issue in writing a short series of clojurescript tutorials (https://github.com/magomimmo/modern-cljs). The problem of sharing in more pages the same js emitted by the clojurescript/closure compilers could be solved, in my case, just removing from the cljs code any js/window setting of properties (i.e. onload) and putting that (e.g (set! (.-onload js/windows) init) call directly in a script tag in the corresponding html pages as: scriptmodern_cljs.login.init();/script and scriptmodern_cljs.shopping.init():/script If you take a look to the last published tutorial (i.e. tutorial 5) in https://github.com/magomimmo/modern-cljs you can find the context I'm talking about.

Instead of making a single page web application, I want to split the application into different pages. Now the problem is, different pages need different js functions. I know that by using cljsbuild I can build different source paths to different js files. So for each pages I can just make a cljs directory and let cljsbuild compile it to a js file to be included by that page. However I wonder if this solution is a little bit overkill for a simple website. Maybe I can put all the cljs file in one directory (hence only produce one js file) and use namespace to split functions for different pages. What solution do you use? Do you think your solution is better than the other one? I want to hear your opinion.

Re: [ANN] ClojureScript release 0.0-1535 with G.Closure 0.0-2029
I've debugged a bit, the underlying cause seems to be that
goog.net.xpc.CrosspageChannel uses goog.async.Deferred, which lives in
third_party.
In my project, I could indeed successfully compile again with the browser
repl, by adding the third-party jar.
This leaves two open issues:
Why the NPE in cljsbuild?
script/cljsc complains about goog.async.Deferred never provided, as it
should. When compiling with cljsbuild, however, the js-sources list
contains an entry which :provides goog.async.Deferred but has an :uri of
nil, which triggers the breakage when mapping javascript-name over it. I
didn't find out where that entry comes from. This is probably a cljsbuild
issue, so I'll amend the ticket if I have time to look into this within a
few days.
So clojure.browser.repl transitively depends on third_party now
Not only that, there are a lot of files in closure lib proper that depend
on goog.async.Deferred, as you can verify by running
grep -r goog.require('goog.async.Deferred') closure/library/closure
from cljs root dir. That begs two questions:
- Are there other third-party libs referred to from closure proper and has
that been the case with older versions?
- Does it still make sense to split closure lib?

I've seen this same NPE in my project. I managed to work around it by

Re: Where did the idea of metadata come from?
Here's one use case: Let's say you want to develop a library that monitors system behavior and resources while functions are executed (or while collections are processed). You might have a collection of monitoring functions (we'll call them sensors) that check various things, like disk I/O activity. We now need a way to annotate our other functions and collections (maps, vectors, etc) with the sensors that concern them. For example, maybe we want to ensure a given function doesn't run off with exponential disk writing (commonly called a 'log explosion') - this defect caused one of the Mars Rovers to crash. One way is to attach the sensors directly to the functions in the form of metadata. You could then run the functions in a special context that executed sensors from any piece of metadata. - - - Another example might be that you want to attached additional specification information to functions, so you can run some sort of analysis/verification against your code - - - It's difficult to spot the best time to apply metadata, since we've become accustomed to working in languages without support for it. Anytime you want to convey programmatic meaning about entities themselves, metadata is an elegant solution. I hope this helps a little.

Re: First foray into clojure - questions for new project
cemerick made a screencast of how to get started with Clojure, which takes you through getting started with the tools, and making a web app. It is probably a great place to start: http://cemerick.com/2012/05/02/starting-clojure/ For details on the Clojure web stack, I really like this guide: http://brehaut.net/blog/2011/ring_introduction Note that on Clojure the web stack is made up of a bunch of small libraries. They are almost all based on ring. The guide above describes the common choices. -- Dave -- You received this message because you are subscribed to the Google Groups Clojure group.

Dynamically building SQL queries with core.match dynamic variables
G'day all,
I am building a reporting interface on top of a database with a star
schema. The star schema makes it very easy to restrict queries by various
combinations of dimension. Some combinations are legal; others are not.
Hence core.match. The number of possible combinations is large, and I would
like to provide a simple API for setting up the dimensional constraints
before running a query.
I have in mind to use dynamic variables because in generating reports, a
few separate queries to the database are required - always with the same
dimensional constraints for a particular instance of a report. It is a pain
to pass a large number of parameters down the call stack - all the way from
the interface to the presentation layer, to the mapping layer which
ultimately builds and runs the query against the db. It would be even more
of a pain to update all calls with new parameters every time I add a new
dimension to the database.
So the interface would look something like this:
(binding [*dimension1* ... *dimension2* ... *dimension3* ...]
(get-fact-1-aggregates mandatory-dimension-restriction)
(get-fact-2-aggs mandatory-dim-rest)
)
Or more concretely if you like a bit of context:
(binding [*drill-name* DR1 *hole-name* h1 *from* timestamp *to*
timestamp2]
(do-something-with (drilling-aggregates 123))
(do-something-with (reaming-aggregates 123))
)
Where 123 would be a company ID set by the user's login credentials and
since it is mandatory and will always be passed I have put it as a formal
parameters.
Here is a rough draft of the code I have in mind.
I would very much appreciate any comments as to the sanity of this
approach, and any other ideas on how to do it better.
Specifically - any better ways of building the query??
Note: I have not populated all the legal combinations of variables so the
match would grow.
Thanks!
David

code waiting on something - cannot debug - driving me insane!!!
Hi all,
I've had this unbelievable problem for some time now but I'm sick and
tired of ignoring it! It is literally driving nuts...Due to the nature
of the problem my terminal hangs and Eclipse crashes altogether
(potentially losing work)!
So what is the problem...Well I really don't have a clue! it is pretty
obvious that my code is waiting on something but it only happens when
I've got a dependency on a namespace of mine which uses seesaw. It is
basically my gui...the bad behaviour is exhibited every time I try to
reload my namespace after having opened a JFrame regardless of having
done anything on the frame! I mean the same happens if I open it and
close it straight after!
anyway, I managed to mock the behaviour with a minimal example:
-

:players 2

(.fillRect g x y tile-size tile-size)) )
(draw-grid d g)

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

Re: code waiting on something - cannot debug - driving me insane!!!
Just a wild guess, but if something's shown on the screen,
#'draw-tiles will probably get invoked to paint the canvas and it
might end up blocking on the #'curr-game promise.

Re: code waiting on something - cannot debug - driving me insane!!!
Hello,
As of the freeze of Eclipse: you're probably using 0.10.1. A problem
of hangs in relation with the way Counterclockwise was talking to the
repl has been fixed in the beta. You could either switch right now to
the beta channel ( http://ccw.crand.net/updatesite-betas/ ) either
wait until Thursday, I'll deliver what is currently in beta into a new
stable release (0.10.2)

ANN: Spyscope 0.1.2
Spyscope is a library that allows you to write very little code to get threadsafe tracing of your Clojure. Example: (println #spy/d (+ 1 2 3)) traces the execution of the form '(+ 1 2 3) Spyscope also supports interactive querying of trace results with a repl toolkit (see README) This version of spyscope has a few new features: - Spyscope now handles mutable objects correctly! - The README includes directions on enabling Spyscope in every project with some Leiningen profile settings. - Herwig Hochleitner has become the first contributor :) To use, just include [spyscope 0.1.2] in your project.clj (or follow the directions in the README to enable globally). You'll need to (require 'spyscope.core) somewhere if you don't add it as an injection. See https://github.com/dgrnbrg/spyscope for details.

The original project is already on github...I just committed the dummy namespace as well so you can have a look... so, do: git clone https://github.com/jimpil/Clondie24.git cd Clondie24 lein2 repl (load-file Clondie24.games.dummy.clj) (ns Clondie24.games.dummy) (-main) then close the frame without doing anything and try evaluating anything (e.g (:name details)). it goes without saying that the same thing happens in all other proper games as well... thanks a million for looking into this :-) Jim On 13/11/12 22:35, Laurent PETIT wrote: Could you create a small lein2 project on github with what you previously pasted in this thread correctly spread over files, etc., so that it's really quick to reproduce the error?

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

Re: [ANN] ClojureScript release 0.0-1535 with G.Closure 0.0-2029
I agree with Herwig, in that if the ClojureScript JAR makes use of goog.async.Deferred, which is from the third party library, then the JAR really needs to depend on the third-party library. I doubt that lein-cljsbuild is the only thing broken by this -- I expect this would break things like piggieback as well (really, anything that depends on ClojureScript but lacks an explicit dependency on the third-party stuff). I could hack a third-party dependency into lein-cljsbuild, but I would prefer to just wait until a new ClojureScript is released that addresses this issue. -Evan -- You received this message because you are subscribed to the Google Groups Clojure group.

run-jetty doesn't shut down the server after ctrl+c?
Hi, all.
I am playing with the `ring` library in `repl`.
After using `run-jetty` to start a server,
I typed `ctrl+c` to send the SIGINT signal,
this ended the `run-jetty` function, but it didn't kill the server:
user= (require '[ring.adapter.jetty :refer [run-jetty]])
user= (require '[ring.util.response :refer [response]])
user= (*run-jetty* (fn [request] (response Hello world)) {:port 3000})

3000}) ; now try to run it again

And I can still access the Hello World example with localhost:3000.
Is this a bug?

core.match - how to simplify patterns with repeated guards
Hi all, I have a core.match pattern that looks something like this: (def !nil? (complement nil?)) (match [*a* *b*] [(a :guard !nil?) nil] (dosomething a) [nil (b :guard !nil?)] (dosomething b) [(a :guard !nil?) (b :guard !nil?)] (dosomething a b) :else (throw (Exception. Not allowed)) The point is that in every case I guard the variable using !nil? I would like to shorten my code: (match [*a* *b*] [(!nil a) nil] (dosomething a) [nil (!nil b)] (dosomething b) [(!nil a) (!nil b) (dosomething a b) :else (throw (Exception. Not allowed)) But I can't figure out how to write the !nil macro. I've tried: (defmacro notnil [sym] `(~sym :guard (complement nil?))) Which looks right in expansion: (macroexpand-1 '(!nil foo)) - (foo :guard (clojure.core/complement clojure.core/nil?)) But I cannot use this in a match: (let [foo nil bar 2] (match [foo bar] [(!nil foo) 2] foo :else :notfound)) CompilerException java.lang.AssertionError: Invalid list syntax foo in (!nil foo) Why!!?!??! I guess its got something to do with the fact that match itself is a macro? Is there some other way that I could extend match to only match when the variable is not nil?
