Writing tests for a live trading API?
Hi all. I'm still relatively new to Clojure and I haven't spent much time on testing before. I've recently written some libraries to talk to Bitcoin exchanges (clj-havelock, clj-btce, cryptick), and I'd like to add tests to them. I'd like some advice around how to test against a live service (there is not test service available) where there's a financial impact if something goes wrong (someone buys/sells by accident). My manual REPL-testing usually involve creating several orders with price spreads that are unlikely to execute. For instance, selling 1 Litecoin for 1 Bitcoin. Buying 1 Bitcoin for $5 USD. My concern is if someone runs the tests with bad inputs, resulting in real orders being executed. I can write tests that pull in API credentials from a file in my home directory, and define price ranges for orders outside the normal spread. These could then be fed into the tests. However, would it be better to try and mock the trading API responses rather than do it live? Or perhaps require a flag to run dangerous tests? Ultimately I want to be able to demonstrate the libraries are mature with good test coverage, but I'm worried about the right approach. Any advice would be appreciated.

Re: Clojure + BDD + TDD + Pairing...
Yes I think replica driven development is sctualy TDD :) they probuably didnt call it that back in the good old lisp days.

Re: [ANN] Session 0.1.3 - A live-coding environment for Clojure
I do like that Gorilla is distributed as a lein plugin, so I can easily start it up in the context of my project alongside my classpath and my code. Would a plugin make sense as an option for Session? marc On Tue, Mar 25, 2014 at 6:07 PM, kovas boguta kovas.bog...@gmail.comwrote: On Tue, Mar 25, 2014 at 3:05 PM, Jony Hudson jonyepsi...@gmail.com wrote: the way you aggregate things in the rendered output is just the way you'd aggregate the values. I think these are the core ideas which make both of the renderers powerful. I'm highly in agreement with this POV. The way most JS libraries to do it, which is you supply a DOM element to the lib and then it populates it with more content, drives me completely insane. It makes things impossible to compose or algorithmically generate, you gotta write logic yourself to built up the structure and tie everything together. Specifically, with respect to extensibility, my aim with Gorilla was to make it as extensible as possible from the Clojure side, as I'm primarily I think this is a real benefit of the Gorilla way. You can create renderers at the REPL itself, since the rendering happens within the same evaluation environment. I think this is a sound idea, and not necessarily an either/or choice. I'm thinking about a way to have some form of rendering within the evaluation environment as well, but it requires more hammock time. One obvious use case is elliding large outputs. Also, it would be pretty interesting to see if Session's renderers could be reused inside Gorilla. It would be great if we could standardize on the rendering side of things, so content created in these systems can flow between them.

Concurrency, Parallelism, and State. And Zombies.
I've added a new chapter to Clojure for the Brave and True, Concurrency, Parallelism, and State. And Zombieshttp://www.braveclojure.com/concurrency/. Here's an excerpt: === In this chapter you'll learn what concurrency and parallelism are and why they matter. You'll learn about the challenges you'll face when writing parallel programs and about how Clojure's design helps to mitigate them. Finally, you'll learn a big boatload of tools and techniques for writing parallel programs yourself, including: futures, promises, delays, atoms, refs, vars, pmap, and core.reducers. Also, there will be zombies. === I hope you all find it useful and entertaining :) Daniel -- You received this message because you are subscribed to the Google Groups Clojure group.

[RFC] Roundtripping namespaced xml documents for data.xml
Hi, I'm taking a stab at namespaced xml support: http://dev.clojure.org/jira/browse/DXML-4 I've uploaded a patch, that should implement 1:1 roundtripping, fully preserving prefixes and xmlns declarations: http://dev.clojure.org/jira/secure/attachment/12899/roundtrip-documents.patch This doesn't implement any advanced serialization or deserialization strategies described in the design page: http://dev.clojure.org/display/DXML/Fuller+XML+support However, it allows such strategies to be implemented by transforming clojure data structures, hence it should be a suitable common representation for any namespaced xml needs. I'd like to work on some namespace-related treewalking next, most importantly normalizing prefixes and default namespaces, so that one can actually parse namespaced xml. Meanwhile, I'd be delighted if you could try out the patch on any (well-formed) namespaced xml you have at hand and see, if it roundtrips correctly. kind regards -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Garden, Thorn - Looking for contributors
Hi Joel, I think this is a good idea. We've discussed one of my pain points; particularly *Exploring Garden At Rules*. Our thread basically looked like the below (last few messages ellided). Now, for the moment, I indeed went back to *SCSS*, because *i)* it did what I wanted out of the box and *ii)* I took a look at garden code and it wasn't clear to me how *cssfn*and *defcssfn* solved my *@import* problem. So I'd imagine there are a few more of those kinds of edge cases with which I'd need to wrestle. And it's sort of on me, to fix and contribute, like you said. But at the moment, I'm just strapped for time, and needed something that worked. Also, I've neglected garden-watchhttps://github.com/twashing/garden-watch, which is another use case that I needed filled. Ie, I have an external designer. And I'd just like him to work with *edn*, and have *CSS* be spit out. So that's my 2 cents. And if I were to have those things working now, I'd ditch *HAML* and *SCSS*. *1. * Hi Joel, I'm playing around with garden a little, and wanted to ask you a question about the at rules. If I execute the below command, I get the result output. *(css (at-import url(http://fonts.googleapis.com/css?family=Gentium+Book+Basic:700italic http://fonts.googleapis.com/css?family=Gentium+Book+Basic:700italic)))* *= @import \url(http://fonts.googleapis.com/css?family=Gentium+Book+Basic:700italic http://fonts.googleapis.com/css?family=Gentium+Book+Basic:700italic)\;* However, I need the result CSS to have the below string, without quotes, etc. *@import url(http://fonts.googleapis.com/css?family=Gentium+Book+Basic:700italic http://fonts.googleapis.com/css?family=Gentium+Book+Basic:700italic);* Now, of course, I peered into the sourcehttps://github.com/noprompt/garden/blob/master/src/cljx/garden/stylesheet.cljx#L48, and tried just passing in the url. But that doesn't give me the output I want either (has quotes + missing url). *(css (at-import http://fubar.com http://fubar.com/))* *= @import \http://fubar.com http://fubar.com/\;* Is there a correct way of calling this? Otherwise, is there a way to just pass through raw CSS, from my input edn / clj? Thanks for any insights. *2. * Hi Tim, You can do two things here. Use garden.stylesheet/cssfn to create a temporary css function: (def url (cssfn :url)) Use garden.def/defcssfn to do essentially same thing: (defcssfn url) You can then use either of these approaches to achieve the result you're interested in. (css (at-import (url http://example.com/;))) Otherwise, is there a way to just pass through raw CSS? People have asked me about this a number of times and it's something I've generally been against from the start. It leads to dirty hacks and strange bugs which are usually the result of operator errors. By eliminating the number of places where one can pass raw strings Garden can ensure correct output for most cases and in turn the number of issues that might be opened. Of course, you can still do wacky stuff inside selectors. Feel free to ask your questions in the issue tracker as well. It's nice to have these answers documented there for future users. ...

Although many folks seem to be interested in it, there's certainly not as much adoption of the library as I'd like to see. Sass, Less, and (god help us) pure CSS still appear to be the default choices for many people writing web applications in Clojure. This is something I'd like to change... but I need *your* help! No, no. Put down the phone. Don't look for a KickStarter URL. It's nothing like that. How you can help Garden I'm looking for individuals who are interested in the following: - improving the compiler code - improving/extending existing API's - building an interface to the CSSOM I'm also open to good 'ol fashioned suggestions, pain points you've experienced using the library, or flat out letting me know what it would take to get you to choose Garden over the alternatives for your next project. How you can help Thorn Thorn is very young project and has no official release yet. So what is it? At the moment it's the beginnings of a Sass Parse Tree transformer; something that will take CSS/SCSS/Sass code and give you Garden code. There's a lot of fabulous libraries available in Sass and I'm sure it's a big factor when choosing how to go about CSS generation. I'm looking for individuals who are interested in the following: - accurately transforming CSS/SCSS/Sass to real Clojure code targeting Garden - accurately transforming Less to real Clojure code targeting Garden Why? I deeply believe that being able to author CSS in Clojure or ClojureScript is a
not quite getting refs
I've looked, but can't find, a discussion of the choice of a history mechanism for refs. I can't understand why the transactions just don't check #'identical? for the ref value, rather than maintaining a history queue. In other words, I don't see why (dosync (ref-set foo @foo))) should cause other ongoing transactions, that use foo, to retry. Nothing about foo has changed that will alter a retried transaction. Since an #'identical? mechanism would seem to - be easier to implement - be faster to check at the end of a tranaction - cause fewer retries it must be that I don't really get it yet. Does anyone have a doc pointer that would help with the details? -- You received this message because you are subscribed to the Google Groups Clojure group.

If you really want something that can be called repeatedly and returns something different each time (rather than just iterating through an infinite sequence, which seems like it would be the more functional-ish approach): user (defn cycle-gen [input] (let [iter (atom (cycle input))] (fn [] (let [v (first @iter)] (swap! iter rest) v #'user/cycle-gen user (def colors (cycle-gen '(red green blue))) #'user/colors user (colors) red user (colors) green user (colors) blue user (colors) red user (colors) green user (colors) blue On Wed, Mar 26, 2014 at 12:59 PM, Christopher Howard cmhowa...@alaska.eduwrote: Hi.

Re: creating a map
For reasons unclear to me, (into {} ...) expects a sequence of 2-element
*vectors*, not just 2-element collections. partition returns a seq of lists,
not vectors, which is why you're getting that exception. You could try (into {}
(map vec (partition 2 2 12))) instead.

finding lein templates
The lein help docs suggest finding templates with https://clojars.org/search?q=lein-template but the result is incomplete, and inaccurate. Using lein-template (with quotes) in the search field produces more accurate results, but they're still incomplete. parseapp/lein-template, for example, doesn't show up. Is there an accurate, complete way to search for lein templates? -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] Session 0.1.3 - A live-coding environment for Clojure
If someone can figure out how to include the datomic transactor within a lein plugin, then its a possibility that can at least be considered. Overall though, I'm not sure its worth the effort. Session is more of a standalone app, like Light Table. If anything, the packaging should move towards that scenario, rather than the other way.

The way most JS libraries to do it, which is you supply a DOM element to the lib and then it populates it with more content, drives me completely insane. It makes things impossible to compose or algorithmically generate, you gotta write logic yourself to built up the structure and tie everything together. Specifically, with respect to extensibility, my aim with Gorilla was to make it as extensible as possible from the Clojure side, as I'm primarily I think this is a real benefit of the Gorilla way. You can create renderers at the REPL itself, since the rendering happens within the same evaluation environment. I think this is a sound idea, and not necessarily an either/or choice. I'm thinking about a way to have some form of rendering within the evaluation environment as well, but it requires more hammock time. One obvious use case is elliding large outputs. Also, it would be pretty interesting to see if Session's renderers could be reused inside Gorilla. It would be great if we could standardize on the rendering side of things, so content created in these systems can flow between them.

Re: How did you learn Clojure?
This is awesome, thanks for sharing Aditya! (Thank you to all who shared as well!) I agree with your concept of whatever makes the work real for oneself, and this is where I'm struggling a bit. I think finding an O/S project and contributing to it would do the trick, but we'll see. Thanks for all the great information! Best, Marcus On Mar 23, 2014, at 9:22 PM, Aditya Athalye aditya.atha...@gmail.com wrote: Marcus, Thanks for asking the question and instigating this discussion. A bit late into the thread, but I just want to narrate my experience so far as I'm a Clojure n00b (actually, I'm really a programming n00b). I found 4clojure and Clojure Koans useful, to get an initial feel for the language and some of the basic ideas contained therein. I used (and use) Halloway's Programming Clojure to understand the basic concepts. I also found it incredibly helpful to attend a hands-on (fantastic) Clojure workshop that @ghoseb conducted. I'd term this phase as picking up some of the motor skills. I think the following minimum set of things helps become creatively productive with Clojure: - Clojure's primary data structures and sequence abstraction - Manipulation of collections / sequences - Core functions (it's sufficient to be only peripherally aware of macros / protocols/multi-methods / concurrency semantics, to begin with... They reveal themselves through libraries, once one deep-dives into those through daily use.) - REPL-driven development / the inside-out flavour of FP (particularly to visualize and plan intermediate data transformations that will lead to the final output of the function; inspecting types and classes of things, and trying to understand the various errors one produces.) Beyond that IMHO only a real project will provide the context and the constraints, both of which are required to produce focus. Ideally this project would involve ongoing development by other people. By happy accident I happen to be writing a fair amount of Clojure for browser automation, with clj-webdriver, at a company where Clojure is the workhorse of our server-side software (@helpshift). My particular situation has the following characteristics: - Specific problem domain - Write clojure daily - Read clojure daily - Get and do peer-reviews of code by other (often way way better) programmers - Fast feedback cycles (= 1 day) - Heavy use of at least one library from the Clojure ecosystem... - to have to keep cross-referencing the docs, - be forced to look into library functions when you misuse them (therefore read s'more code by an orders of magnitude superior engineer) - and having to do double-takes at the fundamentals (especially when abstractions leak http://www.joelonsoftware.com/articles/LeakyAbstractions.html) - Bonus: other people happen to depend on this work, so there's no easy way to slack off thinking if something particularly nasty starts to block progress :-) - Bonus: reading application error logs to see what's happening under the hood Also, I'm working through Dimitri Sotnikov's Web Development with Clojure, and I have the Clojure cookbook handy to look through for ideas. I tend to use Clojuredocs's quick reference several times a day (http://clojuredocs.org/quickref/Clojure%20Core), and often read core docs and library docs to understand what I just did that so magically worked! :) Eric Normand's video series also looks very interesting (http://www.purelyfunctional.tv/). Beyond that, I found working through SICP has given (is giving) me the tools to reason better about Clojure's data structures and about functional concepts in general (hat tip @ghoseb, again). As I try to pick up more working proficiency, I intend to explore different approaches to writing web apps with Clojure/Clojurescript (through small projects using ring/compojure, Hoplon, Pedestal, Caribou, Om... I may actually try to write and rewrite the same small project, with at least two or three of these libraries.) Afterthought: Initially I struggled with the notion of real projects. Now, I prefer to interpret it as whatever makes the work real for oneself, as opposed to being predicated on utility to lots of people, or on novelty (I'd argue it's actually better to solve problems other people have solved many times over).

One more question about invoking java methods from Clojure
I am working on a project that requires me to get the size of a file and access it's last date of modification. It seems like the java methods .length and .lastmodified could be pretty handy in this situation. I am, however, having a bit of trouble wrapping my head around how to access a java method from a clojure project. Some examples I have seen import the java classes directly, as you would in a standard java project, whereas others seem to take a different approach. I decided to import java.io.File and try to get the length of a file: (defn get-length [file] (println (.length file---a rather crude representation of my effort. When I ran this, no exceptions were thrown and it gave me a length, only that length was the number of words in the file name I provided, not the actual size of the file. It seems as though clojure may have a different length function built-in, but I'm not sure. So to get to the overall point: what is the standard way to access java methods from clojure (if there is one)? Do I simply need to import the java class, or is there much more to it that I am not yet understanding? Any tips would be great. I am new and loving the language, but a bit confused.

Re: How did you learn Clojure?
Chiming in a bit late, but here was my path: * Read Land of Lisp by Conrad Barski. This was my first real contact with lisp and functional programming. I found it challenging, but the book is well-written and the technique of teaching through writing games was perfect for me. It uses common lisp which is almost baroque compared to Clojure, but it was helpful later in getting a better sense of Clojure's roots. Also, most of the classic lisp books out there use common lisp * Tried to write my own web-based game using common lisp. This was true fun and I learned a ton * Read On Lisp by Paul Graham. It is an excellent book * Was introduced to Clojure through a talk given by Alan Dipert at my workplace * Learned Clojure by skipping around Clojure in Action, Programming Clojure, and Clojure Programming. Settled on Clojure Programming. * projecteuler.net has been a good help * I've been teaching Clojure to folks at work, which forces me to deeply understand the material * At the same time, I've kept building little web apps to solidify my knowledge. One of them, http://gratefulplace.com, is actually used :) I feel like I know enough to get stuff done, but there's still so much more to learn. Most recently I've been brushing up on math/logic so that I can better understand the more mathy texts whenever I encounter them.

Re: data associated with a particular state
I would use 3 records: (defrecord DownNode [] SomeInterfaceApplicableToDownState (wake-up [_] (-WaitingNode)) ... InterfaceApplicableToAllNodes ...) (defrecord WaitingNode [] SomeInterfaceApplicableToWaitingState (shutdown [_] (-DownNode)) (execute [_ job-id] (-RunningNode job-id)) ... InterfaceApplicableToAllNodes ...) (defrecord RunningNode [job-id] SomeInterfaceApplicableToRunningState ... InterfaceApplicableToAllNodes ...) After all, you won't be bashing the state of node in place, you will be constructing a new node at each modification. (unless you define the attrs mutable) On Tue, Mar 25, 2014 at 5:20 PM, László Török ltoro...@gmail.com wrote: AFAIK the only thing that records do not support compared to StructMaps is namespaced keyword lookup, i.e. (:some-ns/a-key a-record).

You can just `assoc' any other key-value pairs as in any other map. Also, have a look at records - I think StructMaps have been deprecated (or at least aren't recommended anymore) for some time now. A record (`defrecord') will do pretty much the same, just nicer ;-) On Tue, Mar 25, 2014 at 1:51 AM, cmhowa...@alaska.edu wrote: Hi. I'm very new to Clojure, but I've read most of the functional programming tutorial http://java.ociweb.com/mark/clojure/article.html . Suppose I have a data structure called node that can be in one of a number of different states -- namely, down, waiting, and running. Suppose that in the running state, the node has a job-id number associated with it, but such a number is not applicable in the other two states. Should I add an extra field, and only check that field in the running state, like so... (defstruct node :state :job-id) Or is there some better, or more clojure-ish, way to approach this? If I was doing this in Haskell, I think that I would perhaps make some kind of algebraic NodeState data type, and have the JobId only attached to the Running constructor. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: creating a map
into expects that because it is implemented with conj.
(conj {} [:foo :bar])
{:foo :bar}

For reasons unclear to me, (into {} ...) expects a sequence of 2-element

lists, not vectors, which is why you're getting that exception. You could
try (into {} (map vec (partition 2 2 12))) instead.

Hi all,
I was wondering why this doesn't create a map 1 - 2 :

Must be yet another misunderstanding of mine.

Re: How did you learn Clojure?
A technique I use whenever I need to learn a new language is to write the same application I already have in another language. I generally choose downloading nzbs from usenet as it can involve a number of interesting programming techniques, at least enough to give you a pretty good idea of how a language handles things like: * threading and work queues (downloading files concurrently) * socket io (writing a simple nntp client) * xml processing (parsing nzb files) * binary encoding/decoding (yenc implementation) * curses style ui * web ui * command line arguments * configuration * signal handling * testing (haha kidding) TBH I usually get about 50% of the way through and have enough of a handle on the language at that point to abandon my efforts and move on.

This was my first real contact with lisp and functional programming. I found it challenging, but the book is well-written and the technique of teaching through writing games was perfect for me. It uses common lisp which is almost baroque compared to Clojure, but it was helpful later in getting a better sense of Clojure's roots. Also, most of the classic lisp books out there use common lisp * Tried to write my own web-based game using common lisp. This was true fun and I learned a ton * Read On Lisp by Paul Graham.

It's actually excited me so much I'm considering hanging up my PM hat and diving back in the programmer pool again! My problem appears to be 1) focus, and 2) fear. Focus because I can't (yet) earn a living on a clojure project, so it must be done during off hours. Fear because it's harder and more different than the old OO languages I've used in the past. So I'm curious: how did you learn Clojure well enough to be proficient with it, or how are you working on learning it? Anyone else facing the focus + fear dilemma?

Re: Concurrency, Parallelism, and State. And Zombies.
I really enjoy your post, especially the emacs one, I've been using vim for five years, and always want to learn something about emacs, but didn't have any good material to get start. That post is very useful for me. Thanks, Di Xu 2014-03-26 21:45 GMT+08:00 Daniel Higginbotham nonrecurs...@gmail.com: I've added a new chapter to Clojure for the Brave and True, Concurrency, Parallelism, and State. And Zombieshttp://www.braveclojure.com/concurrency/. Here's an excerpt: === In this chapter you'll learn what concurrency and parallelism are and why they matter. You'll learn about the challenges you'll face when writing parallel programs and about how Clojure's design helps to mitigate them. Finally, you'll learn a big boatload of tools and techniques for writing parallel programs yourself, including: futures, promises, delays, atoms, refs, vars, pmap, and core.reducers. Also, there will be zombies. === I hope you all find it useful and entertaining :) Daniel -- You received this message because you are subscribed to the Google Groups Clojure group.
