Re: idiomatic extension to - / -- ?
What I think is the interesting part of the question is the inclusion of the word idiomatic. I'm not sure swiss-arrows is idiomatic... that said I don't know what would be considered idiomatic here.a One solution I know of for examples like this is: (- 2 (+ 2) (#(* 1 % 3))) I'm not sure this is idiomatic either, but it at least has the benefit of requiring no additional dependencies.

clojure key destructuring motivation
With apologies for 3 questions in 1 day:
(def a {:foo {:cat 20
:dog 30}
:bar hi})
(let [{{cat :cat
dog :dog} :foo
bar :bar} a]
[cat dog bar])
(leth [{:foo {:cat cat
:dog dog}
:bar bar} a]
[cat dog bar])
I don't understand the reason why existing let key destructuring is
backwards
To me, it seems the fictional leth example is much simpler -- the mental
model is just do pattern matching
The current let example seems to be: okay, um, so for cat, you look at
:cat, then you look at :foo, then you think (:cat (:foo a)) -- which seems
much more work and error prone.
Question:
Where can I read up on the rationale behind the current design of map
destructuring in let?
Thanks!

Servlet adapter for ring handlers with support for asynchronous processing
Hi Folks, Is someone aware of servlet adapter (other then pedestal-service) for ring based handlers with support for asynchronous processing as specified in Servlet 3.0+ api ? Given that ring core was already refactored to support such solutions (middleware had been split into wrapping and request modifying functions) it should be not so hard to combine it with core.async go macros to assemble handler chain which supporting async processing and write an adapter to connect it with Servler 3.0+ API - HttpServletRequest.startAsync(), AsyncContext.complete() and so on... If you assembled something similar yourself, or you now about such project (even in development, immature, alpha), please let me know, thank you very much.

Re: Factual is hiring Clojure engineers
Do you consider non US candidates? Wihout extensive data analysis experience? On Saturday, January 18, 2014 7:34:38 AM UTC+7, Zach Tellman wrote: It's been six months since I last announced this, so: Factual is perpetually hiring smart, driven engineers to solve deep problems in data analysis and systems engineering. We have offices in both SF and LA, and remote candidates with a strong background in analysis will be considered. Factual provides an index of things in the world (businesses, places, and products). You can either use this directly via our API [1] to ask questions like what are the three coffee shops nearest to me, or indirectly by giving us your own real world data to enrich and refine [2] [3]. Factual uses Clojure extensively [4], both for realtime systems and batch data analysis. Systems written purely in Clojure handle the following: * realtime intake of 70k datapoints/sec from our partners * batch processing of 7 billion new datapoints every day, comprising terabytes of compressed textual data * generating, storing, and serving 150 million records, refreshed daily Both of these numbers have at least doubled in the last six months, and could very easily do so again. There are also other projects that use Clojure alongside Java to work at similar scales. Libraries developed in the course of working on these projects include: https://github.com/factual/skuld https://github.com/factual/clj-leveldb https://github.com/aphyr/merkle https://github.com/ztellman/clj-tuple https://github.com/ztellman/narrator Several other libraries are on the cusp of being open sourced, when we get a chance. We need people who enjoy using technology as a lever to accomplish amazing things (wasn't it Archimedes who said give me a large enough data center...), who want to work alongside people they can continuously learn from, and who want to be just a little uncomfortable with the scale and scope of their responsibilities. If this sounds interesting, contact me at zach at factual.com. I'm heading up the small but growing SF office, and am happy to talk in person with anyone in the Bay Area who'd like to know more.

[ANN] - modern-cljs integrates a port on emacs of lt-cljs-tutorial By David Nolen
Hi all, the `modern-cljs` series https://github.com/magomimmo/modern-cljs now includes a port for Emacs users https://github.com/magomimmo/modern-cljs/tree/master/cljs-tutorial of the recent lt-cljs-tutorial - A ClojureScript Programming Language Tutorial for Light Table Users by David Nolen. https://github.com/swannodette/lt-cljs-tutorial I consider `lt-cljs-tutorial` the best companion resource for the `modern-cljs` series because it represents the fastest path to start learning the ClojureScript Programming Language as is, in a very interactive way, and from the most competent guy for the language itself. For those not using Emacs or Light Table, it should be very easy to run the emacs port of the David's tutorial with any editor/IDE supporting nREPL. The port has been generated by `cljs-start` lein-temaplate which works without problem with CCW, so the ported tutorial should work as well on it.

The issue here is that clojure's auto-complete takes the JVM state as an implicit parameter, whereas cljs-complete requires an 'env' arg that has to come from somewhere (piggieback has a var that keeps track of repl session state). Ac-nrepl shouldn't be able to eval code, that means it's being coupled to the JVM state, which won't do for cljs or other sorts of repls-on-repls.

To me, it seems the fictional leth example is much simpler -- the mental

The current let example seems to be: okay, um, so for cat, you look at

much more work and error prone.

Where can I read up on the rationale behind the current design of map

That's not really true. For example:
(let [{:keys (foo bar)} map]
...)
Here it is actually on the right (noting that left and right are
very relative in this case).
If I were to guess, I would say that the example above is the reason for
the design – :keys seem useful more often than naming individual keys.
Of course, I'm just guessing.

Re: Functional purity and globals in Clojure
we do this using Graph Could you show a simple example of this? I think this might be a good topic for a blog post. On Thursday, September 12, 2013 6:35:20 AM UTC+2, Jason Wolfe wrote: At Prismatic, we do this using Graph: https://github.com/Prismatic/plumbing I really try to avoid global vars, but passing through the seven parameters or resources you need through four layers of intermediate functions is also a hassle. Graph makes it easier to define your service in a functional way, instantiate it with your parameters, and the data automatically flows to the leaves where it's needed. When we leave the Graph core and enter ordinary function land, resources and parameters are passed through as a nested map, which at least means you only have a single context argument rather than a mess of args. It's not a complete solution, but I think it's worked pretty well for us thus far. On Tuesday, September 10, 2013 12:19:35 AM UTC-7, Alexandr Kurilin wrote: I'm trying to determine how to best deal with the concept of globals in Clojure. Say I have a map of configuration values for my Ring app, populate at app startup from disk or env, and I need to reference the contents of this map from all over the project. Assuming MVC, models and controllers all would be interested in its contents. I just want to clarify that the question is not so much about configuration as it is about dealing with state that many different components in an application might be all interested in. This is an issue that seems to arise very often. I'm seeing a couple of options here: - Pass the configs map along with each Ring request with some middleware, and then down every subsequent function call that might eventually need it. It's a bit of a hassle since now you're passing more data, potentially increasing the # of parameters, or forcing you to use a parameter map everywhere where you might have passed along just 1 primitive. Nonetheless, this is as pure as it gets. - Def the configs map in a namespace somewhere and refer to it from wherever, just like global state. The trick is now that now you're no longer certain what e.g. your model functions are expecting there to be in the system and testing becomes trickier. Now you have to either lein test with a separate set of configurations (which doesn't actually give you much per-test granularity) or use with-redefs everywhere to make sure the right test config state is being used. - Something in the middle where perhaps you agree to never directly reference the configs map from your models (again, thinking MVC here) and instead only ever access it from controllers, and pass the necessary options along down to the model functions. This way you can test both controllers and models in isolation in purity. Ultimately I want to contain the chaos of having to know internal implementation details of my functions at different layers and want them to be easily testable in isolation. It does seem like the first option is the most straightforward, but I'd be curious to find out what those of you who have deal with the problem for a while would recommend. Purity all the way, or are there patterns that can give you the best of both worlds? Or what else? -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: oob schemas, re: The Language of the System
Ok, so consider a different system (besides google) that handles the JSON example. If it has no prior knowledge of the date field, of what use is it to know that it's a date? What is a situation where a system reading the JSON needs to know a field is a date, but has no idea what the field is for?

He gives as an example of such a schema a JSON encoding where an out-of-band agreement is made that field names with substring date refer to string-encoded dates. However, this is exactly the sort of thing google does. It finds dates, and other data types, heuristically, and not through the formats of the web being self-describing or extensible. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: clojure key destructuring motivation
Map keys need to be unique. Therefore, it's tidy for the symbol to be the key to the destructuring map.

The general justification for the current behavior is that the thing
being
bound is always on the left and the expression defining it is always on
the
right.
That's not really true. For example:
(let [{:keys (foo bar)} map]
...)
:keys acts as syntax here. The symbols being bound (foo and bar) are
still on the left and the expression map is on the right. Or if you
prefer, in each binding the thing being bound is first and the expression
is last.
Here it is actually on the right (noting that left and right are
very relative in this case).
If I were to guess, I would say that the example above is the reason for
the design – :keys seem useful more often than naming individual keys.
Of course, I'm just guessing.

Slide for context:
{:media-type application/edn
:language de
:charset UTF-8
:encoding deflate}
With that on-screen, he says:
...and we have an encoding, which can be for example, deflate or gzip or
like that, um, which we don't care about a lot, I think, on this side of the
server, because we can use like transparent proxies to do all those
on-the-fly gzip things for us, but it's possible.
Presumably, he's talking about something like putting a Clojure app
behind an nginx frontend server, where handling gzip is as simple as
adding 'gzip on;' to the 'server {}' configuration block. (So, you
don't care about gzip'ing on the Clojure side of the application, you
care about it on the transparent-proxying-server side.)

Re: core.async count in a channel
@Meikel, I like your solution. Its key advantage is that you have enable arbitrary functionality in the monitoring of a channel. Since I am new to Clojure, and I bet others are too, I was subconsciously thinking about creating a new kind of channel (monitored channel). This solution does something similar, by defining a new output channel that is a copy of the previous channel while enabling monitoring. You've done this without a new type of class. I particularly like this better than simply adding count because it solves the problem of *when* to call count for monitoring. Your code calls count iff count changes. Regardless of implementation, a monitored channel is a good thing. Not all channels have zero queue.
