Re: Migrating from nrepl.el to cider
This is a me too. I've found this seemingly related https://github.com/clojure-emacs/cider/issues/367 This appears to be a cider problem more than a clojure issue, perhaps directing this inquiry there would be more beneficial? Anyway, my fix is to ignore it - it seems that my repl works fine and I'm able to get work done despite it. I'm using CIDER 0.5.0alpha, so I guess I'm expecting some rough edges. The url I posted above seems to suggest that They are aware of the issue. On Tuesday, December 31, 2013 7:56:46 AM UTC-8, Gary Trakhman wrote: I've seen the pprint error on startup often.

Re: How can I improve this?
I've been finding uses for Brandon Bloom's transduce mini-library left and
right lately. There is a class of problems where you want to track some
state as you process a seq, and transduce.lazy/map-state enables you to do
that (https://github.com/brandonbloom/transduce).
Here's my solution using it. It is concise and stateless:
(defn uniqify [coll]
(map-state (fn [elem-times-seen x]
(let [x (if-let [times-seen (elem-times-seen x)]
(str x _ times-seen)
x)
elem-times-seen' (update-in elem-times-seen [x]
(fnil inc 0))]
[elem-times-seen' x]))
{}
coll))

[beginner] How do I make a button that could interact with indicator?
HI everyone, I am new to Clojure in terms of practice. I like the philosophy of Clojure and I want to start using it. I need to build a simple model: button and indicator (progress bar). Button interacts with indicator. That's it. When the button is pressed - indicator fills, when the button is not pressed - indicator depletes. Where do I start? Give me a hint.

Andy and Nicola has done truly amazing work with this release!

It analyzes Clojure source code in Leiningen projects, reporting things that may be errors. Installation instructions are in the documentation here: https://github.com/jonase/eastwood For example, did you know that if you use clojure.test to write tests, and have multiple deftest definitions in the same namespace with the same name, then the tests in all but the last deftest will never be run, whether those tests would pass or fail? Eastwood can find those duplicate names, as well as other occurrences of the same Var name defined more than once. Eastwood can also warn about misplaced doc strings, calling deprecated functions or Java methods, expressions that are suspicious because they always return the same value (e.g. (= expr) is always true), expressions whose return value is not used and appear to have no side effects, and a few others. See the documentation linked above for a complete list. Jonas Enlund wrote the original version of Eastwood with the help of several other contributors. Version 0.1.0 is an update by Jonas, Nicola Mometto, and myself. It uses the new Clojure contrib libraries tools.reader for reading the code, and tools.analyzer and tools.analyzer.jvm for parsing the source into abstract syntax trees, making it straightforward to write many of the linters. Thanks especially to Nicola Mometto for tireless enhancements and bug fixes to those libraries. You can file issues on the Github issue tracker if you encounter problems, but please read the Known Issues section of the documentation before filing problems. Several issues have already been discovered, and their causes documented, while testing Eastwood on most of the Clojure contrib libraries, Clojure itself, and over 35 other open source libraries.

While this is an alpha release, during the last months a big amount of bugs have been fixed thanks to the work of Andy Fingerhut who moved the Eastwood[3] linter from Ambrose's analyzer to tools.analyzer.jvm; thanks to this, the analyzer has been run with success on a large number of popular clojure libraries including almost all clojure contrib libraries and clojure's own namespaces, thus proving that it's effectively working.

Re: [ANN] Cloact 0.1.0 - Yet another React wrapper for ClojureScript
Hi Dan, This seems like a really smart approach to me. I've been playing with a number of ways of structuring a large Cljs application recently - and the way Cloact cooperates with atom derefs is pretty inspired. It's flexible, it's fast, it's natural - and it makes transition from a non-React codebase easy (trivial in my case since I already using Hiccup). Seriously great stuff, thank you for sharing this! BTW for those looking for single-state snapshots (for undos, tooling, debugging, etc.) - all you'd need to do is merge any individual atom snapshots that constitute your full application state. It should be easy to extend Cloact (or something like Reflex https://github.com/lynaghk/reflex) to do the state tracking automatically.

Re: How can I improve this?
On Sat, January 11, 2014 9:22 pm, Alex Baranosky wrote:
There is a class of problems where you want to track some state as you
process a seq
This is an interesting exercise. I find said class of problem comes up
fairly frequently and I usually end up with something scary-looking using
reduce or lazy-seq that I'm never quite satisfied with. I often feel
there's some missing flow control mechanism just out of reach.
As another point of comparison here's a straightforward imperative version
(of the simplified problem):
(defn unique [words]
(let [occurrences (java.util.HashMap.)]
(for [word words]
(let [n (get occurrences word 0)]
(.put occurrences word (inc n))
(if (zero? n) word (str word _ n))
i.e. if a tree falls in the woods... style mutation. :-)
and transduce.lazy/map-state enables you to do that
(https://github.com/brandonbloom/transduce)
The imperative solution led me towards something like the for-like form
of map-state. A macro that's a hybrid of for and loop such that it
takes both for and loop style bindings:
(defn unique [words]
(for-loop [word words] [occurrences {}]
(let [n (get occurences word 0)]
(yield (if (zero? n) word (str word _ n))
(assoc occurrences word (inc n))
Imagine yield is somewhat like recur in that it takes new values to
bind for the next iteration but its first argument is the sequence element
to return for the current step. Like recur yield must be in the tail call
position.
The above might expand into this:
(defn uniquify [words format]
((fn uniquify* [occurrences words]
(lazy-seq
(let [[word rest] words
n (get occurrences word 0)]
(when word
(cons (if (zero? n) word (str word _ n))
(uniquify* (assoc occurrences word (inc n))
rest))
{} words))

Re: [ClojureScript] [ANN] Cloact 0.1.0 - Yet another React wrapper for ClojureScript
Thanks a lot Peter! Btw, there is already code that comes from Reflex in Cloact (even if it is mangled quite a bit by now). Very undocumented, and probably a very poor api, though... See ratom.clj/.cljs. There is for example a run! macro that will execute its body every time a deref'ed atom is changed. Quite another thing is if it is a good idea to do that :-) If possible, I'd say it is better to keep state that belongs together in a single atom. /dan On 11 jan 2014, at 16:58, Peter Taoussanis ptaoussa...@gmail.com wrote: Hi Dan, This seems like a really smart approach to me.

Re: [ClojureScript] [ANN] Cloact 0.1.0 - Yet another React wrapper for ClojureScript
Quite another thing is if it is a good idea to do that :-) If possible, I'd say it is better to keep state that belongs together in a single atom. Am looking at this from a performance point of view. You're marking components as dirty when there's any change in an atom being deref'ed by the component, right? But I'm guessing it's quite common for a component to be dealing with only a small subset of the data within a larger state atom. (This is what Om's cursors are addressing, it seems). In that case (please correct me if I'm wrong) - the number of needless rerenders will grow with the number of component-irrelevant bits of information in each atom. One simple way of addressing that is to use more, smaller atoms - or to use views on atoms (as Reflex does). For example instead of marking a component as dirty when @my-atom changes, we could mark it as dirty only when `(:relevant-submap @my-atom)` changes. Does that make sense, or am I misunderstanding something? -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Also, React is fast enough that a few re-renderings won't even be noticeable most of the time.

Re: [ClojureScript] [ANN] Cloact 0.1.0 - Yet another React wrapper for ClojureScript
But it would probably be better to just pass (:relevant-submap @my-atom) to a sub-component. The subcomponent will only be re-rendered when its arguments (i.e the params map and possible children) changes. Ahh, gotcha. Of course, thank you! Also, React is fast enough that a few re-renderings won't even be noticeable most of the time. Unless React actually has to change the DOM the cost is very low. Okay, also good to know. Very excited to start playing with this properly soon. All the best, cheers! :-) -- -- You received this message because you are subscribed to the Google Groups Clojure group.

HttpKit, Enlive (html retrieval and parsing)
I'm just playing around with tool kits to retrieve and parse html from web pages and files that I already have on disk (such as JDK API documentation). Based on too little time, it looks like [http-kit 2.1.16] will retrieve but not parse html, and [enlive 1.1.5] will retrieve AND parse html. Or is there a whole built-in parse capability I'm missing in http-kiit? Also, http-kit doesn't seem to want to retrieve content from a file:/// url, whereas enlive is happy with both local and remote content. I'm just messing around, I wanted to have some REPL javadoc logic that didn't fire up a browser or use the swing app (whose fonts are unreadable for me, and half a day spent trying to change it was not fruitful). Any tips or suggestions? Just don't want to make sure I'm missing obvious things. Thanks! -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: HttpKit, Enlive (html retrieval and parsing)
Java has HTTP retrieval built in.

Re: HttpKit, Enlive (html retrieval and parsing)
I don't recommend using java's built in HTTP retrieval (by passing
java.net.URL object to enlive html-resource function).
Not only is it significantly slower then using clj-http (which uses
apache-http client under the hood), but it's also unreliable
when issuing more parallel requests.
Current enlive library supports plug-able parsers, the default one is
TagSoup, but you can switch it very easily for example
for JSoup by setting *parser* dynamic var.
You can have a look at one of my little projects where i used enlive for
html scraping
herehttps://github.com/janherich/lazada-quest/blob/master/src/lazada_quest/scrapper.clj
,
in this case, i used clj-http as
http client:
(ns lazada-quest.scrapper
(:require [clojure.string :as string]
[clj-http.client :as client]
[net.cgrand.enlive-html :as html]))
(defn fetch-url
Given some url string, fetch html content of the resource served under url
adress and return
it in the form of enlive nodes
[url]
(html/html-resource (:body (client/get url {:as :stream}
It would be straightforward to replace use of clj-http with http-kit
synchronous api, or asynchronous api with some changes

Re: obtain # of elements currently on a channel?
Any API that lets you peek at the state of a channel is a surefire source of race conditions. So no, public API-wise, there isn't any way to do what you want. In theory, you can peek at the internals using reflection to get that information, but don't do that! Instead, you can simply *count* yourself. Stick an extra go-loop on either end that swaps an atom with inc or dec.

Re: obtain # of elements currently on a channel?
I have a another stupid question: How is this a race-condition / a source of problem given that: * all I want to do is to read, I'm not writing / modifying In particular, the sole goal of this read is to show a counter saying there are XYZ people ahead of you in line.

Re: ClojureScript integration with Emacs/Cider ?
In response to this thread, I've hacked lein-cljsbuild to dump the compiler state, and built a version of autodoc to parse it and generate api docs. I'm trying to figure out how exactly cider and austin will talk to each other so I can make it happen, and I approach that I'm considering now is to add a 'complete' operation to the piggieback middleware, since Bozhidar says that it should work out of the box. The information's available, and I've demonstrated how to parse it in my autodoc-cljs port. Hopefully that's enough. I've created a lein-cljsbuild issue to possibly integrate this stuff and evoke further discussion. It has a screenshot of autodoc generated from a compiler dump and links to the implementations. https://github.com/emezeske/lein-cljsbuild/issues/283 On Tue, Jan 7, 2014 at 5:35 PM, Colin Fleming colin.mailingl...@gmail.comwrote: Great, let me know if you have any questions.

I'll try using it. Do you plan to explicitly support ClojureScript? Do you have an ETA? That would be awesome, because viewing the implementation of Clojure's core libs is very valuable and from what I understand, there are differences between Clojure and ClojureScript (e.g. protocols are at the bottom in ClojureScript) and it would be valuable if I could click on a function and see its ClojureScript specific code and documentation.
