Re: optional first map argument
What about adding this new binding syntax?
[(attrs map?) contents] ; optional first map argument
[(attrs map? {}) contents] ; with default value
[(s String)]
; is shorthand for
[(s #(instance? String %))]
; a function taking optional map, vector, string arguments.
[(m map?) (v vector?) (s String) n]

I often need to do this when writing hiccup helper functions:

I found this post, but considering that it is 4 years old, is there
any new library developed to help with this situation?.

Re: Best IDE
My 2c - I use emacs, I love it. I don't inflict it on my team, and I
strongly disagree with it being easy. To learn the basics, yes, but full
fluency? If you have someone fluent in IntelliJ, with the major keystrokes
in their muscle memory, and an instinctive familiarity with all the gui
features, they are not going to be as productive in emacs in a hurry.
Also, while I love the power of emacs, it's really struggling these days
with the text-only idiom. Speedbar is no replacement for a graphical
directory tree. Coloured text blocks next to modified lines is no
replacement for being able to hover over a changed line and having a pop-up
(a real pop-up, that is) tool tip that shows you the changes since the last
commit. And don't get me started on selecting fonts and other
customizations...
For an IDE for someone not from a vim/emacs background, I'd use whichever
of Intellij or Eclipse is most familiar. Eclipse is more clojure-friendly,
but it has many warts as well - if you know IntelliJ, it's clojure plugin
is definitely good enough.

You've got to be kidding. That's like suggesting that the path of
least resistance in taking a trip to L.A. involves climbing the north
face of Everest instead of using an airplane. In particular, the
learning curve of emacs and the north face of Everest, in a shocking
coincidence, turn out to have exactly the same geometry. :)

Re: Best IDE
I used eclipse emacs+ for about a year for java code once I had started
writing clojure in emacs, it made me more productive, but it was a hassle
to set up.
Unfortunately, when eclipse updated itself to juno, it broke, and there is
still no support.
Going forward, I think this is a more compelling solution to get some of
the benefits of eclipse in emacs: https://github.com/senny/emacs-eclim
But, I think it's not quite there yet.

nginx is a web server, and I don't think what you want. You probably want to use apache httpclient or a wrapper library. I hate all the wrapper libraries, and I've used clj-http and clj-apache-https.

Re: WSS Clojure client
Didn't mean to sound so negative, but in my experience the apache-wrapping ones are too many layers of abstraction, and the moment you need a specific feature httpclient provides and the wrapper doesn't, you're on your own and have to rewrite a bunch of stuff. Http-kit looks elegant, but it's likely less tested than the java libs.

[ANN] alpacas: a new Clojure source viewer
Alpacas is an application that displays Clojure source code with forms shown as nested boxes, doing away with parenthesis altogether. Run it with lein run and it will display its own source code. There is partial support to navigate the source code by moving a cursor with the left and right arrows. Obviously the idea would be to be able to edit the source rather than just viewing it. Some clever key combinations or even the mouse might help accomplish that. It is still a proof-of-concept and not very useful at the moment, but I think it might turn into something useful, or even innovative shall somebody decide to put some effort into it. I didn't work at it in a while but I decided to publish it (under GPL) so as to be able to include it in my cv (you can mail me at ndrch...@gmail.com for Clojure job offers).

core.match -- adding extractors?
Howdy David Co.,
One of the *really* nice things about Scala's pattern matching is the
ability to extend pattern matching using extractors. The research is
presented in
http://lampwww.epfl.ch/~emir/written/MatchingObjectsWithPatterns-TR.pdf
The practical aspects allow testing and transforming at pattern matching
time. For example:
object AsInt {
def unapply(in: String): Option[Int] = try {Some(in.toInt)} catch {case
e: Exception = None}
}
foo match {
case AsInt(number) = number + 1
case _ = 0
}
More importantly, one can use extractors to test external things:
object AsJsonFile {
def unapply(fileName: String): Option[JSON] = ... // find the file, load
it and parse it as JSON
}
What are your thoughts on adding extractors to the pattern matcher?
Thanks,
David

Re: [ANN] alpacas: a new Clojure source viewer
Just fyi, most clojure libs are published under EPL or Apache licenses, of course the choice is up to you :-). GPL has some restrictions that would prevent the lib from being used in many projects. from the EPL wikipedia page: 'The EPL 1.0 is not compatiblehttp://en.wikipedia.org/wiki/License_compatibility with the GPL, and a work created by combining a work licensed under the GPL with a work licensed under the EPL cannot be lawfully distributed.' Since clojure itself is EPL, not sure what the implications are. Seems like apache is compatible, but only in one direction. The project would have to be itself GPL.

Making things go faster
Folks, I've been doing Clojure coding for the last couple of weeks and really love the language... and the community is fantastic. But the development cycle is slow. I'm coming from mostly Scala and a little Java. In Java, there's no REPL or anything... but the compile/test cycle is very fast. So, I can make a few changes to code, type mvn test and see the results typically in less than 2 seconds (my MacBook Pro and my Linux desktop). In Scala, the compile cycles are slower than in Java because the Scala compiler is doing a whole ton more. But in sbt (Simple [ha ha] Built Tool), one is always building/testing in the same JVM instance so the JVM is warmed up. A change code and run tests cycle is typically as fast as it is in Java. For example, Changing something significant in the net.liftweb.util package and doing a recompile and test takes about 9 seconds. This is running 450 tests. My Clojure development cycle is much slower. On my MacBook Pro (3rd gen i7 quadcore processor, 16GB of ram), each time I make a change and re-run the test for Plugh ( https://github.com/projectplugh/plugh ) it takes about 20 second and there are only 4 tests. On my desktop Linux box (i7-3770 with 32gb of RAM) it takes about 4 seconds to run the 4 tests. I also ran stuff on a very old ThinkPad (core 2 duo with 4GB ram running Linux Mint 15) and the test cycle takes 12 second. So... the questions: * Is there a faster cycle than to change code, change tests and type lein test to see the results? * Is there a way to keep everything in a hot JVM (I've done a little research on Nailgun... but it seems to be out of vogue) so there's no JVM start-up penalty? * Is there a reason for the huge disparity between my MacBook Pro and my desktop box?

Re: core.match -- adding extractors?
I've looked at extractors a little bit, but I would need to investigate
further. Does this offer any more power than supporting arbitrary function
application in patterns?

One of the *really* nice things about Scala's pattern matching is the
ability to extend pattern matching using extractors. The research is
presented in
http://lampwww.epfl.ch/~emir/written/MatchingObjectsWithPatterns-TR.pdf
The practical aspects allow testing and transforming at pattern matching
time. For example:
object AsInt {
def unapply(in: String): Option[Int] = try {Some(in.toInt)} catch {case
e: Exception = None}
}
foo match {
case AsInt(number) = number + 1
case _ = 0
}
More importantly, one can use extractors to test external things:
object AsJsonFile {
def unapply(fileName: String): Option[JSON] = ... // find the file, load
it and parse it as JSON
}
What are your thoughts on adding extractors to the pattern matcher?

Re: Looking for Clojure freelancers
Hi Peter, (I'm going to follow your suggestion and reply publicly.) I would be interested in collaborating with you. You'll find my contact details and a summary of my experience in xavi.caballe.pro . I come from the Rails world (I'm also an ex-Objective-C, ex-Java, and ex-Perl developer). I still work with Rails but my current language of choice is Clojure. My main open-source contribution is noir-auth-app, a base web app with authentication, https://github.com/xavi/noir-auth-app . This is a byproduct of a side-project that I'm developing in Clojure. Also, recently I worked for a month in an all-Clojure shop doing the full-stack development (Clojure + ClojureScript + Datomic) of a new feature. I'm more a generalist and I am happy working both in the back-end and the front-end. As for databases, I'm comfortable with SQL, but with Clojure I've only worked with MongoDB and Datomic for now. I'm based in Barcelona and my rate is €25/hr but I'm open to negotiate it. Cheers!

What I'd like to ask is this: if anyone's interested, drop me an email (*ptaoussanis at taoensso.com*) with some basic info including: - Contact details (would prefer an international telephone number also if possible). - Your experience / informal CV (open-source stuff is my preferred reference, especially if it's Clojure-based). - Any particular areas of interest/expertise (e.g. you especially want to work with Datomic, backend services, Clojurescript, whatever). - Your rate + how negotiable it'd be and/or how it'd scale with longer-term jobs. I can then keep your details on file and give an occasional shout if something comes up that I could potentially use you for. Whole thing'd be about as informal as it gets: terms will vary based on the particular job, but I'll include all of that in the email so you can decide if/when something grabs your fancy.

The only advantage to function application is that you could conceivably
memoize the results of the unapply because they are not supposed to be
side-effecting.
Also, I'm unlikely to dive into any feature addition related issues until
all these pressing bugs in JIRA are squashed.
No worries.
I will not open a ticket at this time. I just want to put the idea out

Re: Making things go faster
midje makes each test a top level form, so test runs happen as a side effect of code loading, which means you cannot really run tests in a good way from the repl without doing some kind of ridiculous forced code reloading. I would definitely recommend staying far away from midje, if you want a tight test loop the repl is your best bet, and midje's design makes using it from the repl really awkward. I have heard horror stories about drip jvms being launched with stale args, etc, but that is anecdotal, and a while ago so maybe it is great, I don't use it and have no interest in it, largely because I use the repl.

My 2c - I use emacs, I love it. I don't inflict it on my team, and I
strongly disagree with it being easy. To learn the basics, yes, but full
fluency? If you have someone fluent in IntelliJ, with the major keystrokes
in their muscle memory, and an instinctive familiarity with all the gui
features, they are not going to be as productive in emacs in a hurry.
Also, while I love the power of emacs, it's really struggling these
days with the text-only idiom. Speedbar is no replacement for a graphical
directory tree. Coloured text blocks next to modified lines is no
replacement for being able to hover over a changed line and having a pop-up
(a real pop-up, that is) tool tip that shows you the changes since the last
commit. And don't get me started on selecting fonts and other
customizations...
For an IDE for someone not from a vim/emacs background, I'd use
whichever of Intellij or Eclipse is most familiar. Eclipse is more
clojure-friendly, but it has many warts as well - if you know IntelliJ,
it's clojure plugin is definitely good enough.
