ClojureScript: can't (:use) protocol in another namespace
Hello,
I'm not sure if what I'm doing is supported or whether I'm doing it
incorrectly.
I have two ClojureScript namespaces:
(ns foo)
(defprotocol SomeProtocol
(some-function [this]))
(ns bar
(:use [foo :only (SomeProtocol)]))
(defrecord SomeRecord
SomeProtocol
(some-function [_] :quux))
The protocol function is compiled as though SomeProtocol was defined in the
bar namespace, e.g.:
bar.SomeType.prototype.bar$SomeProtocol$ = true;
bar.SomeType.prototype.bar$SomeProtocol$some_function = function(this$) {
var this__14211 = this;
return\ufdd0'quux
};
This causes an error at runtime.
Should I be able to do this, or should I stick with (:require foo) and
foo/SomeProtocol?
Cheers,
Stuart

Re: a goal succeeding when given another goal succeeds for all elements in a list
Ok, so the function (let's name it for-all) is: (defn for-all A goal that succeeds if all goals succeeds. [goal first-param list] (fresh [head rest] (conso head rest list) (goal first-param head) (for-all goal first-param rest))) it takes 3 parameters. 1. a goal, 2. first parameter to the goal 3. list of parameters which will be applied as a second one to the goal. The 'for-all' goal succeeds when goal 'goal' succeeds for all pairs: first-param a, first-param b, first-param c , where a, b, c, are elements of 'list' list. Conso is a goal which takes 3 parameters. 1. an element, 2. list of elements, 3 list of elements. And succeeds when 3rd list is equal to 2nd list with prepended element ( L = H | R ) In goal 'for-all' conso is used for destructuring a 'list' list and store its head and rest in fresh variables. For such obtained head we try to apply 'goal' goal AND continue recursively in the same fashion with the rest of the list.

No, that certainly is not going to happen. Dynamic vars are not the
right way to build an API in Clojure.
Could you elaborate on that please? I see that dynamic variables are used quite
often to give the user the ability to configure/change the behaviour of a
library. That approach is often coupled with a macro that changes the bindings
of dynamic variables. An example of this can be, for example, found in
criterium [0]
--- snip ---
;;; Progress reporting
(def ^{:dynamic true} *report-progress* nil)
(defn #^{:skip-wiki true}
progress
Conditionally report progress to *out*.
[ message]
(when *report-progress*
(apply println message)))
(defmacro with-progress-reporting
Macro to enable progress reporting during the benchmark.
[expr]
`(binding [*report-progress* true]
~expr))
--- snip ---
I guess that my confusion stems from your very general statement and my
inexperience so I would be happy if you could give more details. I find using a
dynamic variable in a library in the way exemplified above to be OK and maybe
(??) even idiomatic. It is just hard to get Clojure idioms right if a voice
keeps nagging in the back of your head saying Dynamic vars are not ...
Thanks!

By interactive authentication I mean, it can be used for primary end

could
eventually provide google/facebook like session overviews and log off
remote sessions.
The following bearer tokens are implemented:

* Non standard session ('access_token') for use in interactive

Currently it supports Redis and in memory for tokens, apps and users.
There
is a very easy protocol to implement to add further stores. I will
probably
add a separate one for korma and for datomic. These will be released as
separate projects.
For an interactive demo of it:
lein run -m clauth.demo

Bug recognizing tail position as default value in maps?
Is suspect this being a bug: When a recursive function call is used as a
default value in a map, its tail position is not recognized. The problem
can be easily demonstrated using the fixpoint function. The fixpoint
function is usually defined as
(defn fix [f x] (let [v (f x)] (if (= v x) x (recur f v
To avoid the 'if' special form, we can use a map. The compiler rejects
compilation and does not recognize (recur f v) to be correctly in tail
position.
(defn fix2 [f x] (let [v (f x)] ({x x} v (recur f v
CompilerException java.lang.UnsupportedOperationException: Can only recur
from t
ail position, compiling:(NO_SOURCE_PATH:41)
Avoiding tail recursion lets fix2 compile but not execute properly:
(defn fix2 [f x] (let [v (f x)] ({x x} v (fix2 f v
#'user/fix2
(fix identity 1)
1
(fix2 identity 1)
StackOverflowError user/fix2 (NO_SOURCE_FILE:44)
Strange, isn't it!?

Hi,
(defn fix2 [f x] (let [v (f x)] ({x x} v (recur f v
recur is not in the tail position. The call to the map is the tail call.
So the result is as expected.

New release of Domina (now with reworked eventing)
Some of you may already be aware of of Domina, a jQuery-inspired DOM manipulation library I've been working on. It's been out there for a while, but I just finished up a round of changes that I think bring it to a certain degree of completion for basic use (although there's definitely a lot of cool stuff that still remains to be added). Most notable is a new set of eventing functions; I hope they'll provide an easy-to-use, low-level foundation for building more complex data- and event-driven web applications. Please check it out: https://github.com/levand/domina/ Feedback, pull request, etc. are welcome.

Re: Bug recognizing tail position as default value in maps?
Sure? The semantics of the default value corresponds to a 'if', doesn't it?
From this viewpoint, the default value is in tail position. And why does
the non-tailrecursive version not run as expected?

Re: Bug recognizing tail position as default value in maps?
Using a map instead of if means that it is evaluated as a function call.
Unlike the if form, function calls eval their arguments. So the (recur)
form is getting eval'd prior to being passed to the map/function, which
isn't a tail position.
That's why if is a special form/macro, not a regular function (like maps
are).

Help with clojurescript code for google charts
Hi,
I am trying to use google charts from clojurescript, however cant get it
working. I have included both the js code from google's site and my
clojurescript conversion. Any help in figuring out the problem will be
appreciated.
Thanks,

JS Code -
script type=text/javascript src=https://www.google.com/jsapi;/script
script type=text/javascript
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',
'width':400,
'height':300};
// Instantiate and draw our chart, passing in some options.
var chart = new
google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
/script
CLJS code -
;;clj-js and $ are functions from jayq
(defn add-rows []
(let [data (js/google.visualization.DataTable.)]
(.addColumn data string Topping)
(.addColumn data number slices)
(.addRows data [[Mushrooms 3] [Onions 1] [Olives 1]])
data))
(defn chart-options []
(clj-js {:title How much Pizza i ate last night
:width 400
:height 300}))
(defn get-chart []
(js/google.visualization.PieChart. ($ div.container div#content)))
(defn draw-chart []

I have two ClojureScript namespaces:

(defprotocol SomeProtocol

(ns bar
(:use [foo :only (SomeProtocol)]))
(defrecord SomeRecord
SomeProtocol
(some-function [_] :quux))
The protocol function is compiled as though SomeProtocol was defined in
the bar namespace, e.g.:
bar.SomeType.prototype.bar$SomeProtocol$ = true;
bar.SomeType.prototype.bar$SomeProtocol$some_function = function(this$) {
var this__14211 = this;
return\ufdd0'quux

This causes an error at runtime.
Should I be able to do this, or should I stick with (:require foo) and
foo/SomeProtocol?

Re: a goal succeeding when given another goal succeeds for all elements in a list

The 'for-all' goal succeeds when goal 'goal' succeeds for all pairs: first-param a, first-param b, first-param c , where a, b, c, are elements of 'list' list. Conso is a goal which takes 3 parameters. 1. an element, 2. list of elements, 3 list of elements. And succeeds when 3rd list is equal to 2nd list with prepended element ( L = H | R ) In goal 'for-all' conso is used for destructuring a 'list' list and store its head and rest in fresh variables.

lein-cljsbuild is now becoming the tool of choice for many CLJS devs. One thing I've noticed about domina is that it's not particularly careful about declaration order.

Re: Bug recognizing tail position as default value in maps?
I got it, guys! Thanks a lot! This non-tailrecursive version works as
intended:
(defn fix2 [f x] (let [y (f x)] (eval ({x x} y (list 'fix2 f y)

Am Freitag, 27. April 2012 17:00:52 UTC+2 schrieb Luke VanderHart:
Using a map instead of if means that it is evaluated as a function call.
Unlike the if form, function calls eval their arguments. So the (recur)
form is getting eval'd prior to being passed to the map/function, which
isn't a tail position.
That's why if is a special form/macro, not a regular function (like maps
are).

Sure? The semantics of the default value corresponds to a 'if', doesn't

does the non-tailrecursive version not run as expected?

recur is not in the tail position. The call to the map is the tail
call. So the result is as expected.

Tagged literals: undefined tags blow up reader
Thanks everyone involved for the 1.4 release. One issue: In 1.4, tagged literals need to be defined, otherwise the reader blows up: user= [:a #foo/bar :b] RuntimeException No reader function for tag foo/bar clojure.lang.LispReader$CtorReader.readTagged (LispReader.java:1164) RuntimeException Unmatched delimiter: ] clojure.lang.Util.runtimeException (Util.java:170) This is a show-stopper for using tagged literals as a data interchange format. Its impossible to pass data through your system without every step knowing about what it is. I don't know what the best solution is, so I'm bringing this up here. But however it looks, it would be great if undefined literals were read into some kind of wrapper, and then the reader could go on with its job. -- You received this message because you are subscribed to the Google Groups Clojure group.

Is there a log function that works in clojure 1.3 and above?
Hi All, There exists a log function by Konrad Hinsen http://richhickey.github.com/clojure-contrib/generic.math-functions-api.html But, does it work in Clojure 1.3 and above? If so, how would I start using it without leiningen? Incanter has a log function but whenever I do (use '(incanter core)) to get the log function, a swing window gets itself ready to display charts. This is definitely fixable though. Thank you for your time. -- You received this message because you are subscribed to the Google Groups Clojure group.

eventually provide google/facebook like session overviews and log off

Currently it supports Redis and in memory for tokens, apps and users.
There
is a very easy protocol to implement to add further stores. I will
probably
add a separate one for korma and for datomic. These will be released as
separate projects.
For an interactive demo of it:

I see that dynamic variables are used quite often to give the user the ability to configure/change the behaviour of a library.

Dynamic variables smack of imperative programming to me... When I asked Clojure/core to review c.j.jdbc in the context of a potential future 1.0.0 release, the use of dynamic variables was one of the issues that came up. The current variables will probably remain for backward compatibility but a new API or an extension to the current API will be added that provides a more functional style without requiring dynamic variables - and the existing code rewritten in terms of that new API.
