Re: Update
Well, why write it in primitives when there is a perfectly good compiler from java to primitives? I dont quite understand why you think there would be benefit from manually writing everything with java bytecode. The JVM works with classes, thats how its designed, Clojure itself is just a java library.

Re: Update
The JVM is very class-oriented. It is basically designed for Java, and corresponds pretty much to the things you can do in Java. Code belongs to methods which belong to classes, and calls are made using java method calling conventions. Data has to be stored in primitives, arrays, or objects; and arrays aren't particularly to-the-metal in Java anyway. The Byte Code Verifier keeps what you do fairly simple - eg you can't just leave things in the stack and jump to another method. Even if you wanted to do anything a bit different, the performance of the JVM all comes from the assumptions made while executing the bytecodes at runtime. If you did anything very weird, you'd probably find that these optimizations didn't kick in.

Re: how to convert current time to format i need?
Hi , I didn't verify if that particular formatter comes prepackaged ( I am assuming you are using clj-time since it is not mentioned..) Once you have created your custom formater all you have to do is unparse (clj-time.formatter/unparse date-time-object custom formatter ) . This is there in the readme.. may be you missed it. Sunil.

Clojure for web project? Talk me into it!
Hey guys, I need your help in choosing a web stack for a medium sized website project, which is going to take the better half of my time for the next year. I really want to use clojure, because of various reasons, but have never done web development with it before. Frankly, it’s quite hard to feel confident about such a decision, as there are so many libraries to choose from, many of which seem to be abandoned or with very little (public) momentum. These are the notable features I need on the server side: - Internationalization of content, with multilingual URLs - Authentication through username / password and through xing (oauth) and linkedin (oath2). - Image and PDF upload - A small (and pretty basic) CMS - Beautiful reports renderings - A basic admin backend First, I was thinking along the compojure/hiccup/friend stack. I like it for the simplicity, the flexibility and the abundance of documentation on the web. Unfortunately, I see myself reinventing the wheel a few times with this approach… Then there is caribou. I like that it’s very well documented and that it’s already being used in production. It appears to be the most feature complete solution for the time being. It handles images, has backend scaffolding and i18n. OTOH, authentication isn’t really built-in (other than basic auth, if I got that right) and, it’s very new, so adoption seems to be still low. Also, it is developed in-house, so there’s the risk of abandonment, too. Finally, I took a look at pedestal (services). I like its overall design and I especially welcome the URL generator, which is going to be a boon in larger projects. But all in all, it seems to be little more than a (powerful) routing engine (again, maybe I’m missing something) and lacks internationalization as well as authentication (although I read that the snapshot version of friend will work with it). Also, it is developed in-house and not declared production-ready yet. I don’t feel very comfortable with either choice and would appreciate the thoughts of seasoned clojure web devs on that topic.

Re: Clojure for web project? Talk me into it!
One of the biggest value propositions of Pedestal has always been that it's the only Clojure web server library to support end-to-end async operations. You can do things like have a handler return a core.async channel, or pause/resume the entire web stack multiple times during a single request. Other libraries may support async or streaming responses, but none allow that level of control, so if you need that feature Pedestal is there. Pedestal's routing stack is also data based, that's a pretty big deal if you're used to debugging nested ring handlers that are instances of functions. Data over code...that's the way I like it. But yes, as a whole the entire Clojure ecosystem is built around small composable libraries instead of a monolithic framework. Pick and choose and build your own stack.

Re: core.async and Joy of Clojure
Thank you Timothy, I did watch that talk! In fact, it was one of the videos that really piqued my enthusiasm in core.async. I had no idea that the code was available on github. Good news. I am thinking now about how I could use core.async to do useful/fun things: web-service or browser game, simulation, etc. It will be exciting to see how things develop in the next couple of years. Do you think you might put out a book about some of the stuff you've been working on?

Re: Clojure for web project? Talk me into it!
Pedestal was developed by Cognitect and I would assume they use it on many of their consulting projects. Since future support appears be a major concern for you (rightly so), Pedestal probably fulfills that requirement better than anything else out there right now. Even if you don't need all the features it offers, it's worth considering building your server-side stack around it for that reason alone. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] nginx-clojure v0.2.0 -- Let MySQL JDBC Driver Apache HttpClient Fly With Epoll/Kqueue on Nginx
This is excellent! I definitely think there is a lot of opportunity for fusion between Clojure and Nginx. Clojure's model already supports the cooperating threads model that can simplify Nginx's complex event model, as you have demonstrated. Work has already been done that proves this idea can result in productivity and scale gains (nginx + Lua) It can also greatly simplify architectures by cutting out load-balancers making less to patch for security/stability issues.

Re: Clojure for web project? Talk me into it!
Not to make it more complicated for you, but have you looked at Hoplon too? http://hoplon.io/ I was *very* impressed by the author's presentations, the later of which is https://www.youtube.com/watch?v=wVXjExRiFy0 And podcast about it: http://thinkrelevance.com/blog/2014/03/18/alan-dipert-cognicast-episode-052 It's optimized around single-page web apps. I'm not saying that's what I'd necessarily use for your product; you may want to use all of it, or parts of it (it's modular) along something else. If this kind of approach isn't what you'd use on your front-end, make sure you look at Om, Reagent and Quiescent for that. And obviously, I'm forgetting a few other batteries-included frameworks I've seen (because there are a few, apart from Caribou). On Tuesday, April 29, 2014 4:22:58 AM UTC-4, Bernhard Mäder wrote: Hey guys, I need your help in choosing a web stack for a medium sized website project, which is going to take the better half of my time for the next year. I really want to use clojure, because of various reasons, but have never done web development with it before. Frankly, it’s quite hard to feel confident about such a decision, as there are so many libraries to choose from, many of which seem to be abandoned or with very little (public) momentum. These are the notable features I need on the server side: - Internationalization of content, with multilingual URLs - Authentication through username / password and through xing (oauth) and linkedin (oath2). - Image and PDF upload - A small (and pretty basic) CMS - Beautiful reports renderings - A basic admin backend First, I was thinking along the compojure/hiccup/friend stack. I like it for the simplicity, the flexibility and the abundance of documentation on the web. Unfortunately, I see myself reinventing the wheel a few times with this approach… Then there is caribou. I like that it’s very well documented and that it’s already being used in production. It appears to be the most feature complete solution for the time being. It handles images, has backend scaffolding and i18n. OTOH, authentication isn’t really built-in (other than basic auth, if I got that right) and, it’s very new, so adoption seems to be still low. Also, it is developed in-house, so there’s the risk of abandonment, too. Finally, I took a look at pedestal (services). I like its overall design and I especially welcome the URL generator, which is going to be a boon in larger projects. But all in all, it seems to be little more than a (powerful) routing engine (again, maybe I’m missing something) and lacks internationalization as well as authentication (although I read that the snapshot version of friend will work with it). Also, it is developed in-house and not declared production-ready yet. I don’t feel very comfortable with either choice and would appreciate the thoughts of seasoned clojure web devs on that topic. Please talk me into it! I don’t want to end up with scala and play… :-) Thanks for your thought! Bernhard -- You received this message because you are subscribed to the Google Groups Clojure group.

lein cljsbuild auto ; hook to copy into directory post build
Hi, ## context: I am currently running lein cljsbuild auto It appears that each new compile _overwrites_ the old compile in place, say resources/out ## what I would prefer to happen: every time a new build is triggered, have it write to resources/tmp then, exec rm -rf resources/out; mv resources/tmp resources/out ## why I want this behaviour I'm also using live.js . It appears, that with longer compile times, live.js is pulling in _half completed_ builds from lein -- and giving me very weird errors. Thus, I would like lein to build somewhere else, then after a build is complete, in a single atomic operation, swap the two directories (which I can do via symlinks). Where can I setup a clojure/shell command to be executed every time lein cljsbuild auto successfully completes a build?

Cheers Alex!
See below for the results of yesterday's run of my benchmark suite for
the basic operations. (I'll post some benchmark results for the new
functions in a separate message sometime soon.)
In general, it's fair to expect (persistent) assoc/dissoc to be slower
with data.avl maps, since AVL trees do more work to rebalance
themselves than red-black trees. (That's on average, of course.)
The upside is that lookups in AVL trees are faster on average,
sometimes quite dramatically, due to the trees being shallower. It's
worth pointing out that this really is on average -- individual
timings depend on the path through the tree the lookup operation needs
to traverse, and for nodes at exactly the same position in the tree
the built-ins are slightly faster (23.9 ns vs. 25.5 ns for a lookup
succeeding at the root node, see the (get % 131071) benchmark case
below; as I recall, 0 happens to occupy the same position in both
benchmark maps as well) -- but if we hit a deeper part of a red-black
tree, data.avl is likely to win by a large margin, as in the case of
the 311 ns (data.avl) vs. 588 ns (built-in) result for looking up
29 in the two benchmark maps.
For longer chains of updates -- including construction of instances
with more than a handful of elements -- data.avl wins thanks to its
support for transients; in particular, inserting 30 entries in
ascending order of keys took 197 ns with data.avl's sorted-map during
my benchmark run yesterday vs. 317 ns with the built-in.

Re: Kwargs vs explicit parameter map for APIs?
Having worked through this for java.jdbc (and to a lesser extent for
CongoMongo), I think that I would approach it slightly differently in future:
Provide two functions: one taking a map, one taking keyword arguments; the
latter delegating to the former via {:as opts} and then internal calls can
easily use the map-based argument approach.
One of the additional complexities in java.jdbc (as it stands today) is that
several functions accept an arbitrary number of arguments, followed by optional
keyword arguments as well, so several functions have to parse their argument
lists at runtime. Simplifying that to use a sequence (of current arguments)
followed by a map (of options) would make several things easier inside the
library, removing a lot of apply calls, as well as providing an API that is
more amenable to dynamic call construction...
I still think the keyword argument approach is far more readable to _users_ -
and it's also what was recommended in the Clojure Library Guidelines right up
until a few days ago:
http://dev.clojure.org/pages/viewpage.action?pageId=9142444
Reid McKenzie changed it on April 24th, completely reversing the previous
recommendation from Unroll optional named arguments to Don't unroll optional
named arguments - compare version 6 (from Stuart Halloway) with Reid's edits
in versions 7-11:

Hi all,
I'm working on an API at the moment, and I'm balancing whether to use inline
keyword args which I would destructure in the functions, or whether to just
pass an explicit params map as the last parameter. Comparison of the two
options in case I'm not explaining myself well:
Kwargs:
(class/create-class :instancelist
:description My description
:implements (keys class-methods)
:methods (calculate-my-methods))
Map:
(class/create-class {:instancelist
:description My description
:implements (keys class-methods)
:methods (calculate-my-methods)})
A lot of APIs I've seen have favoured kwargs, and it undeniably makes for
some pretty code - Seesaw is the best example I've seen here, the API is a
thing of beauty. However it seems to me to have some issues:
If I want to delegate to another call from within an API function and use the
same arguments, it's really awkward: (apply delegate (mapcat identity args))
or some similarly awful black juxt magic. Or of course writing out all the
parameters again, but that's even worse.
It's more difficult to make parameters optional based on some runtime
criteria since the params are baked into the function call. I guess this is
usually dealt with by making the calls handle nil for a particular parameter.
Both of these are much easier when passing an explicit map. Any preferences
here, from either writing or using APIs like this?
Cheers,
Colin

Re: Proposing a new Clojure documentation system (in Clojure)
Phil, I like the general idea of the Valentin's proposal, but I don't understand every bit of it. It sounds complicated. Personally, I'd rather see something that's relatively simple, and good enough, than something that's perfect but unwieldy. If it's too difficult, people won't use it, or they'll waste time, or feel that the Clojure community expects them to spend too much time on something that detracts from what's important. Can I ask, quite seriously and not intending any sarcasm, what you mean by detracts from what's important? For me, what's important is to communicate ideas, designs, and details from one developer to another so that others can maintain, modify, and extend what exists. I've already held forth on what I think that implies so I won't bore you with it. What I don't understand is your criteria for what's important and how that translates to action.

I'm not saying documentation as a bunch of markdown files sucks.

Re: Kwargs vs explicit parameter map for APIs?
I'm extremely internally torn regarding kwargs. I use them a lot; I know
they hinder composability; but every time I go back to straight maps for
these kinds of things I really don't like all the extra noise characters
and go back to kwargs.
I feel like I really should be using regular maps for all the good reasons
listed, but in practice I don't. Honestly, I don't usually run into the
composability issues too often, so I'm getting by ok with my indulgence
in kwargs, I suppose.
I especially dislike that my non-kwarg fns no-longer can elegantly accept
no options. Let me illustrate:
(defn foo [ {:keys [a b]}]
[a b])
(foo :a 1 :b 2)
(foo)
(defn foo [{:keys [a b]}]
[a b])
(foo {:a 1 :b 1})
(foo {}) ;; -- unpleasant to my eyes, let me reimplement foo
(defn foo
This is also pretty gross
([]
(foo {}))
([{:keys [a b]}]
[a b]))
So, yeah, I'm pretty torn.
I like the option of having kwargs for the outer API shell, and explicit
option maps internally. I've played with that a little as well at work to
some ok success.
