Re: IoT: Clojurescript -> Jerryscript?
Seems like that jerryscript does not fully implement the ecmascript (3 and/or 5). I have tried to run a pretty complex test suite ( https://github.com/funcool/cats tests) under it (that already includes async code with promises and core.async among other stuff) and the code never executes without any error. There are also other js engines that are intended to be used for IoT, such are: v7 (https://docs.cesanta.com/v7/master/), mujs (http://mujs.com/), duktape (http://duktape.org/), ... After trying them all, I found that only duktape can run partially the funcool/cats test suite (core.async and promise stuff fails because of lacks support for setTimeout and other related stuff). If somebody interested on this, I have compiled the code targeting the browser with `:whitespace` optimization level (simple and advanced should also work as expected). Then, manually prepend to the compiled file `var window = this;` because duktape seems like does not have global object that is needed in some cases. v7 seems like it does not have support for labeled statements that are used in the cljs compiled code so it just fails with syntax error. I suspect that jerryscript fails in the same way, but without any error message. Andrey.

#{:ann} funcool/struct - yet another validation library for Clojure and ClojureScript.
Hi all. I am happy to announce the first public release of funcool/struct validation library. https://github.com/funcool/struct Why an other? I have started on my project using well know and very nice library: bouncer; that has worked pretty well for me, but over time I have needed some features that are missing: such as value coercion and dependent validators. Then, I decided to build a own one. And these are the main highlights of the resulting library: - Validators are defined using plain hash-maps instead of opaque macros. - Optional value coercion (very useful if you want to validate query params or form-data that by default comes as string). - Dependent validators (add the ability to the validator access to previos state, also useful for form-data validation). - Serves pretty well as simple data structure validation in the same way as bouncer or schema works and also works well for validate user input such as query params and forms.

Re: What's the best option similar to Vert.x, Reactor, Nodejs for use with Clojure?
The eventbus of vert.x as far as I know is implemented on top of hazelcast[1] that you already can use from clojure. Make a eventbus like concept on top of hazelcast is pretty easy and it already gives you the autodiscovery and all the "clustering" stuff for free.

For use dewdrop you should know how to work records and closures for fully understand all operations. With cats you should understand how to work only closures. In fact, with ladd and record you are just doing the same thing that clojure.core can do but you are just re-implementing something that clojure.core offers. I think that you are declaring that comp and closures are not obvious because you don't know how they work and your solution is just re-implement them using familiar components for you, and thinking that understand your code will be more easy that understand how comp works (and justifying that you don't want to learn them when the server crashes at 3 AM (that seems a fallacy instead of argument)) This is not about complicated things with strange and not obvious abstractions, is about to understand the language and the facilities that it already provides instead re-implementing everything that one do not know how it works. We have done cats with the same argument that you are defending now here: bring near the complicated and cryptic (non very obvious) abstractions from haskell in clojure using simple and familiar components making the learning curve more affordable.

I agree with your main argument, but I don't know how using records makes
thinks more easy understandable in this concrete case and how using
functions over records will make code slower. Transducers has a performance
improvements over classical transformation compositions, and in this case,
the cats lenses leverage the same technique.

Yes but it implies more api to know, that is not bad but if you limit the
set of new api that one should learn/use, will contribute to more familiar
and easy api. Adding new api also implies more time to understand it and
remember when it should be used.

Yes, I agree with you, the code readability is very very important. But
this concrete case I don't found big differences in code readability:
;; dewdrop
(defn key-lens [k]
(lens.
(fn [d] (get d k))
(fn [d v] (assoc d k v
;; cats
(defn key
[k]
(lens
(fn [s] (get s k))
(fn [s f] (update s k f
The code is mostly the same...

Re: [ANN] dewdrop 0.1.0 -- lenses made simple(r?)
Hi!
I have read the readme and I don't found a big evidence of something wrong
so, nice work!
Furthermore, do you know about https://github.com/funcool/cats ? It has a
lens and traversable implementation for clj/cljs. You can read the related
documentation here: http://funcool.github.io/cats/latest/#lens .
You can found that lenses, using cats approach, are working just like
transducers (function composition), you do not need any special function
for combine lenses, just use comp. One of the readme examples (from your
repository) that combines two lenses, in cats can be written in this way:
(require '[cats.labs.lens :as l])
(def xy-lens (comp (l/key :x) (l/key :y))
;; Or just use (l/in [:x :y])
(l/focus xy-lens {:x {:y 1}})
;; => 1
(l/over xy-lens inc {:x {:y 1}})
;; => {:x {:y 2}}
Happy new year!

Re: JDBC Rollbacks and Exceptions
If I understand it properly, this is a expected behavior in most databases. The common way for solve this, is wrapping the expected to fail code in a sub-transaction (or savepoint in database words). If that code fails, the sub-transaction will be aborted, but the main transaction will continue to be alive. With this approach you not need a complete rollback of the transaction (and no connection reset). The main problem here is that as far as I know, clojure.java.jdbc does not has support for subtransactions. If you nest transactions, the nested transactions does nothing and everything is joined in one unique main transaction. Without aims to do spam, it there alternatives to clojure.java.jdbc that already supports sub-transactions/savepoints [1] and [2] among other transaction strategies.

Help with macro.
Hi! I have a little trouble writing a macro because I'm getting unexpected (for me) behavior. Let see some code: (ns foo.bar) (defn debug [x] (println "debug:" x) x) (defn debug-expr? [expr] (and (seq? expr) (symbol? (first expr)) *(= 'foo.bar/debug (first expr))*)) (defmacro without-debug [& body] (let [body' (reduce (fn [acc v] (if (debug-expr? v) (conj acc (second v)) (conj acc v))) [] body)] `(do ~@body'))) And then I use it from other namespace: (ns foo.baz) (require '[foo.bar :as b]) (macroexpand '(b/without-debug (b/debug 3))) ;; => (do (b/debug 3)) (macroexpand '(b/without-debug (foo.bar/debug 3))) ;; =>(do 3) I expect that the both expressions will evaluate to the same result, but is not. Seems that symbols inside macros are not fully qualified. It there any way to get them fully qualified? I'm missing something? Any help is welcome! Thank you very much.

That is only available when the protocol is extended as interface. As example you can not use this way (a method access to the protocol) if you extend the type/class using `extend` or `extend-protocol`. For remove reflection, you should add the appropriate type hint with the `aatree.nodes.INode` interface (generated automatically when you are defining the protocol).

Re: #{:rant} Questions about contribution policy and clojure compiler source.
Is there any need to speak with this tone and this arrogance? It's just an attempt to improve things, and I think there is nothing negative about it. I think the initial motivation of this email is change things to be better and with good intentions. It make sense to attack good intentions without any needs? We are all adults and we should all be able to talk about issues in a more calm manner, without arrogance and with understanding. This kind of responses not only discourages participating in clojure development, it also damages the community and completely discourages the participation in this mailing list. Personally, this kind of things discourages me completely from participating in this mailing list. My two cents!

Pull request are just for code review and patch attachment mechanism, and bug tracking system for coordinate the efforts. Both them are not incompatible. And django core team is not precisely small.

But some openness would be awesome. As first think that comes in my mind is: have a clear roadmap for Clojure and its core libraries such as core.async. Some channel for requesting features, and the ability to know a opinion of the clojure core team about the possibility of the inclusion of some requested feature. Also would be awesome have more painless contribution process. I'm ok for signing CA, but using patches instead of something like pull requests (with or without additional review tool) is very arcane and uncomfortable process. I don't suggest to change to something similar to "design by committee". I only suggest that make some facilities for contribute may attract more interesting people. And will make more happy excellent contributors like Zach Tellman or Aphyr. I think that things like this are not very complicated to adopt and has a lot of benefit.

#{:rant} Questions about contribution policy and clojure compiler source.
Hi! I have some, maybe controversial, questions... A little bit of context: https://twitter.com/aphyr/status/621806683908542464 Why this is like a normal approach for managing third party contributions to clojure core? This kind of things the only discourages the contributions. Maybe I don't have more context about this concrete case, but seems is not a unique. And in general, I have the perception that the clojure development process is a little bit opaque... An other question: Why the great amount of clojure compiler code has no indentation style and bunch of commented code. It is indented like a freshman. Sorry, I don't want offend any one, but eyes hurt when reading the code compiler clojure (obviously I'm speaking about the look and feel, and no the quality of the code). Some examples: Indentation (or maybe no indentation): https://github.com/clojure/clojure/blob/36d665793b43f62cfd22354aced4c6892088abd6/src/jvm/clojure/lang/APersistentVector.java#L86 Bunch of commented code and also no indentation: https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/AMapEntry.java#L60 If you compare some clojure compiler code with different code snippets from other languages, the indentation is clearly more cared: Kotlin: https://github.com/JetBrains/kotlin/blob/master/core/descriptors/src/org/jetbrains/kotlin/types/AbstractClassTypeConstructor.java#L44 Rust: https://github.com/rust-lang/rust/blob/master/src/libstd/io/buffered.rs#L165 Ceylon: https://github.com/ceylon/ceylon-compiler/blob/master/src/com/redhat/ceylon/compiler/java/codegen/AttributeDefinitionBuilder.java#L233 This is a random list of code snippets from different compilers with indentation that is more human friendly. I don't intend judge any one, but when a I learn Clojure compiler I expect something different. I expect something more carefully done. No body thinks the same thing that me? I think that have a sane, more open contribution policy, with clear and more cared code formatting, is not very complicated thing and is going to favor the clojure and its community.

[ANN] Buddy 0.6.0: Security library for clojure.
Hi! I am happy to announce a new release of buddy, a security library for clojure. Since the buddy is split in different modules, here relevant changes across all modules: buddy-core: - Improved padding's namespace api (has a little breaking change: `unpad!` function is replaced by `unpad`) - Add high level interface for encrypt arbitrary length data using an encryption scheme. With initial support for: `:aes128-cbc-hmac-sha256`, `:aes192-cbc-hmac-sha384`, `:aes256-cbc-hmac-sha512`, `:aes128-gcm`, `:aes192-gcm` and `:aes256-gcm`. buddy-sign: - Code cleaning (removed many builtin crypto primitives that are already implemented and part of the public api of buddy-core). - Fix some hidden bugs related to wrong padding's on the JWE implementation (thanks to new crypto primitives on the buddy-core). - Dependencies updates. buddy-auth: - Dependencies updates. buddy-hashers: - More tests. - Dependencies updates.

Re: Opinion on core.async vs callbacks in abstract APIs?
Hi! Personally I think that manifold has the same problem that core.async. So if you are exposing your api using manifold you are forcing to someone to use manifold. It is not bad, but is the same problem as with core.async. And the same problem with callbacks. If you are using callbacks you are force to people to use callbacks or adapt it to whatever other abstraction. So, independently of the chosen abstraction, you are always forcing the user to use the chosen abstraction or adapt their code to another abstraction. About the original question, I think it depends that you really wants. In some projects I expose api using inter operable with jvm abstractions like (reactive-streams) or promises (completable future in jdk8), in other I just use core.async. There is no single solution I think! My two cents!

[ANN] Catacumba 0.2.0: Asynchronous web toolkit for Clojure
Hi! I'm happy to announce the 0.2.0 release of catacumba, the asynchronous and non-blocking web toolkit for Clojure build on top of ratpack[1] and netty[2]. This release is focused in polish the code base. Here a small list of relevant changes: - Improve session storage api and make it asynchronous by default. - Add support for extensible body parsing. - Add support for interceptors (instrumentation) - Add support for auth facilities. - Update futura library to the last version that adds fully asynchronous publishers. You can see the complete release notes here: https://github.com/funcool/catacumba/releases/tag/0.2.0 Additionally it comes with 3 new example projects: website, interceptor(instrumentation) and single-file app. You can found all information about them here: https://funcool.github.io/catacumba/latest/#examples The upcoming planned relevant changes for the next release: - Make auth asynchronous like now are sessions. - Leiningen template for easy and quick start a basic project. - Message based communication between client and server with STOMP over websocket.

Re: how goeth the STM experiment?
Hi!
Personally, I do not have the opportunity to use refs, but atoms and agens
I have used it in different ways
I have used agents for logging system, thanks to its guarantees of
execution functions in a serial way. This allows heavy multithreading
applications put logs to stdout (or any other destination) and have as
result a consistent log.
An other thing when I have used with agents is implement an async interface
for jdbc like applications. I have a little explication on how it is done
here: http://funcool.github.io/suricatta/latest/#_async_interface
I hope you find it useful.
Cheers.

Re: Metadata loss. What am I doing wrong?
Thank you very much to all!
Now I completely understand the metadata behavior with the reader. I'll try
to adopt eastwood, thanks for the suggestion.
Is clearly that the documentation confuses a little bit.

Re: Metadata loss. What am I doing wrong?
Thanks to both for the responses, but I stil not clearly understand.
The documentation says very clearly that:
In addition to with-meta, there are a number of reader macros (The Reader:
Macro Characters) for applying metadata to the expression following it:
^{:doc "How obj works!"} obj - Sets the metadata of obj to the provided map.
Equivalent to (with-meta obj {:doc "How obj works!"})
(def foo ^:abc [1 2 3]) -> (meta foo) -> {:abc true}
(def foo ^:abc some-func) -> (meta foo) -> nil
(def foo ^:abc 'some-symbol) -> (meta foo) -> nil (In clojure programming
book uses example attaching metadata using the reader to the symbol, but
seems it not works as expected)
Is a little bit confusing. The metadata documentation says clearly that are
equivalent, but are not equivalent.
Thank you very much again.
Regards.

Metadata loss. What am I doing wrong?
Hi!
I have some trouble with clojure metadata / reader and I do not know if I'm
doing something wrong.
I have this code:
(defn some-func [])
(def func ^:abc some-func)
(assert (= (meta func) {:abc true}))
(def data [[:bar (with-meta some-func {:abc true})]
[:baz ^:abc some-func]])
(assert (= (meta (get-in data [0 1])) {:abc true}))
(assert (= (meta (get-in data [1 1])) {:abc true}))
It fails in the first assert and in the last (if I comment the first one
obviously). I do not understand why that form of metadata does not works
as I expect (http://clojure.org/metadata)
Thank you very much.
Regards.

[ANN] [Book] ClojureScript Unraveled
Hi! We (my friend Alejandro and I) are happy to announce the first public version of a ClojureScript book that we are writing. The book is still a work in progress and many chapters are not available yet. We are sure that the book has many spelling errors (we are not native English speakers), so the wording improvements are very very welcome! This books aims to serve as: - a comprehensive introduction to the ClojureScript language and its idiomatic usage, assuming no previous experience with Clojure or functional programming; - a detailed guide of the ClojureScript compiler and the tooling around it; and - a mixed bag of topics that are useful in day-to-day ClojureScript programming. Github: https://github.com/funcool/clojurescript-unraveled Online version: http://funcool.github.io/clojurescript-unraveled/ Feel free to write any comments or feedback. Cheers.

Hi! I'm happy to announce the second alpha of catacumba, the asynchronous and non-blocking web toolkit for Clojure build on top of ratpack[1] and netty[2]. This release is focused in add a great a mount of features missing from the first release and improve some internals for make it more flexible. Here a incomplete list of added features: - Add Server-Sent Events support. - Add CORS support. - Add security related chain helpers (x-frame-options, strict-transport-security, the content-security-policy and x-content-type-options). - Add support for manifold deferreds and streams. - Add support for get/set cookies. - Add basic support for sessions (very experimental and internal api will change in the next version). - Add special functions for add callback function that will be executed when connection is closed and just before send the response to client. - Add dispatch by method to the routing system. - Support for stuartsierra/component You can see the complete release notes here: https://github.com/funcool/catacumba/releases/tag/0.1.0-alpha2 Additionally, it comes with two examples (in the next release I have plans add other two), one for see how we can use prone for better error reporting and other is a multiuser chat using Server-Sent Events and stuartsierra component.

[ANN] Catacumba 0.1.0-alpha1: Asynchronous and non-blocking web toolkit for Clojure
Hi I'm happy to announce the first alpha of catacumba, the asynchronous and non-blocking web toolkit for Clojure build on top of ratpack[1] and netty[2]. Here a incomplete list of things that Catacumba intends to have: - a flexible and extensible way to setup different kind of handlers. - build almost everything up on abstractions for easy extensibility. - support for async handlers (with promise, future, core.async, manifold, reactive-streams, …) - builtin routing with flexible way to chain handlers. - builtin websocket support. - backpressure support out of the box. You can read the detailed rationale and features here: https://funcool.github.io/catacumba/latest/#_rationale Documentation: https://funcool.github.io/catacumba/latest/ Github: https://github.com/funcool/catacumba This is a first alpha; the code and the documentation has great room of improvements but i'm pretty happy with this first preview release.

[ANN] Buddy 0.5.0: Security library for clojure.
Hi! I am happy to announce a new release of buddy, a security library for clojure. Since the buddy is split in different modules, here relevant changes across all modules: buddy-core: - Add support for AEAD mode of operations (gcm) - Add support for AES Key Wrapping algorithms. - Add support for deflate compression algorithm. - Several fixes for padding, codecs and keys namespaces. buddy-sign: - Add support for JWE (Json Web Encryption) specification. With support for all specified (in RFC) content encryption algorithms and good subset of key encryption algorithms, including asymmetric key encryption schemes. - Add support also for JWE and JWS registered claims validation: aud, iss (exp, nbf are already supported previously). - The default JWE and JWS api not raises descriptive exceptions instead of returning a useless nil in case of something goes wrong on unsing/decrypt process (breaking change). - Implement security considerations from https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/ (breaking change because now is more strict with parameters) buddy-auth: - Improved exception based authorization system, removing all java source (now is 100% clojure source). - Add JWE authentication/authorization backend. - Add the ability to match by http method on access rules. - Add the ability to set multiple authentication backends in `wrap-authentication` middleware. - Several bugfixes on all parts of the library.

[ANN]: Octet 0.1.0: A Clojure(Script) library for working with binary data.
Hi! I'm happy to announce the first version of Octet library. _octet_ library offers, not intrusive (without additional wrapping), composable and host independent abstraction for working with binary data. It works out of the box with NIO ByteBuffer, Netty ByteBuf, and ES6 TypedArrays (clojurescript). Github: https://github.com/funcool/octet Documentation: http://funcool.github.io/octet/latest/ Cheers.

[ANN] Buddy 0.4.0: Security library for clojure.
Hi! I am happy to announce a new release of buddy (security library for Clojure). Since 0.3.0, buddy is split from monolithic library in four modules: - buddy-core: Cryptographyc api. - buddy-sign: High level message signing - buddy-auth: Authentication and Authorization facilities for ring based web apps. - buddy-hashers: Collection of password hashers. Relevant changes since 0.3.0: buddy-core: - Add buddy.core.nonce namespace with functions for generate cryptographically secure ivs and nonces. - Add buddy.core.padding with interface to the common padding algorithms. - Function name consistency improvements in almost all api (with proper backward compatibility for almost all changes, see changelog for breaking changes). - Improved low level interface to Hash and Mac algorithms, allowing to the user build own high level abstractions over it. buddy-sign: - Removed generic signing implementation - Add compact signing as replacement for generic (the difference and the purpose is explained in the documentation). - Improved time based validation and fix some related bugs. - Improved error reporting on message validation using Either monadic type. buddy-auth: - Remove generic signed token backend. - Add JWS/JWT backend as replacement to generic signed token backend). - Improved generic authorization system, now it extensible with clojure protocols. buddy-hashers: - Update versions and adapt the code to buddy-core internal api changes. Github: https://github.com/funcool/buddy-core https://github.com/funcool/buddy-auth https://github.com/funcool/buddy-hashers https://github.com/funcool/buddy-sign Documentation: https://funcool.github.io/buddy-core/latest/ https://funcool.github.io/buddy-auth/latest/ https://funcool.github.io/buddy-hashers/latest/ https://funcool.github.io/buddy-sign/latest/ Cheers.

Hi! I am happy to announce a new release of buddy (security library for Clojure). Since 0.3.0, buddy is split from monolithic library in four modules: - buddy-core: Cryptographyc api. - buddy-sign: High level message signing - buddy-auth: Authentication and Authorization facilities for ring based web apps. - buddy-hashers: Collection of password hashers. Relevant changes on some modules: buddy-hashers: - Code refactored in more extensible way (based on multimethods) - Unify in one namespace. Now, independently of hasher you should import only one namespace. - Hasher verification autodetects the hasher that should be used for verify the password. - Add pbkdf2+sha256 and pbkdf-sha3_256 buddy-auth: - Add support for more extensible way to raise unauthorized exception based on slingshot and clojure protocols. - Add clout syntax and some other little improvements from https://github.com/yogthos/ring-access-rules - Bugfixes on some backends related to headers parsing. - Add better examples. Other two modules does not includes new changes or has small and not relevant ones after library splitting. Github: https://github.com/funcool/buddy-core https://github.com/funcool/buddy-auth https://github.com/funcool/buddy-hashers https://github.com/funcool/buddy-sign Documentation: https://funcool.github.io/buddy-core/latest/ https://funcool.github.io/buddy-auth/latest/ https://funcool.github.io/buddy-hashers/latest/ https://funcool.github.io/buddy-sign/latest/ Since this release, each module will evolve independently. I thing, that this approach will help users to include only the necessary parts from buddy instead of including one monolithic library. Cheers.

If that supposition is correct, you have only a little subset of posible keys memoized (the set of keys of your api). In case of user-id, you will memoize the transformation of userId to user-id and for it you only need one cache entry. Obviously, if you transform arbitrary user input, memoize is not a good solution. My two cents! Cheers.

Re: A (foolish) plan to re-invent IO on top of core.async
Some jetty adapters also supports the async interface using core.async: https://github.com/mpenet/jet. Also, for async database access, I'm currently working on suricatta library (sql toolkit on top of JOOQ) and it exposes a simple async interface for execute queries asynchronously in a shared thread pool: http://niwibe.github.io/suricatta/devel/#_async_interface (it needs more polish and improvements but works pretty well for first version).

[ANN] cuerdas 0.2.0: A string manipulation library for clojure and clojurescript.
Hello everybody. I wanted to announce the second release of cuerdas. A string manipulation library for clojure and clojurescript. That release includes a bunch of fixes and improvements suggested in previous release announcement and reddit. Thanks for the feedback! Relevant changes: - Remove Apache Commons Lang dependency (clj). - Add proper nil handling for almost all functions. - Add strip, rstrip and lstrip aliases for trim, rtrim and ltrim respectively. - Rename endswith? and startswith? with ends-with? and starts-with? respectively, but conserve the previously funcnames as aliases. - Add the ability of arbitrary replacements to strip-tags function.

Re: [ClojureScript] Re: [ANN] cuerdas 0.1.0: A string manipulation library for clojure and clojurescript.
Hi! Thank you very much! You are right about nil handling, it should be documented and proper handled. But I'm not completely convinced with ruby behavior for that, in many other implementations in other languages it is slightly different. In my opinion that is more proper behavior: blank? (nil, whitespace chars resolves to true, something else, false) empty? (nil and "" (empty string) resolves to true, something else is false) the purposed whitespace? is synonym of blank? I'll document and add tests for it in next days. Again, thanks for the feedback. Cheers. Andrey 2014-12-24 13:03 GMT+01:00 Sean Johnson : > Very nice work.

[ANN] Suricatta: 0.1.0-alpha - high level sql toolkit for clojure (backed by jooq)
Hello everybody. I wanted to announce the first alpha release of suricatta, a high level sql toolkit for clojure (backed by fantastic jooq library) Main features: - Clear and simple sql executing api. - Asynchronous query execution api. - Lightweight sql dsl. You might be wondering: Yet an other sql dsl? In first instance suricatta is not a dsl library, is a sql toolkit, and one part of the toolkit is a dsl. Secondly, suricatta's dsl don’t intends to be a sql abstraction. The real purpose of suricatta's dsl is make SQL composable, allowing use all or almost all vendor specific sql constructions. Why I should use suricatta instead of clojure.jdbc or java.jdbc? Unlike any jdbc library, suricatta works in slightly higher level. It hides a lot of idiosyncrasies of jdbc under much simpler, cleaner and less error prone api, with better resource management. You can find a complete FAQ here: http://niwibe.github.io/suricatta/#_faq Repository: https://github.com/niwibe/suricatta Docs: http://niwibe.github.io/suricatta/ My apologies for the spelling mistakes in the documentation.

Thank you very much to both for the feedback. I was considered different names in the past (I don't like much clj.jdbc name :( ) and the current name was the election.

In my opinion, saying "I have problems with it, then, it is bad" is very bad argument. I'm not defending git, I'm only criticizing your arguments.

Re: Kwargs vs explicit parameter map for APIs?
Hi!
I have the same doubt!
However, At this time, I prefer use a explicit map instead keywords,
because for me is much clear that using keywords.

[ANN]: Buddy 0.1.0-beta4: Authentication, Authorization & Signing library for Clojure.
Hi! I am happy to announce a new release of buddy 0.1.0-beta4: authentication, authorization and signing library for clojure. Comparing it with previous release/announcement this comes with big api restructuring and simplification. Changes: - As previously mentioned: api restructuring (after this release, api should not change drastically). - Improved documentation example code. - New granular and url independent access rules decorator. - New simple token auth backend. - Few additional methods for signing (initial work for add support for json web token) Github: https://github.com/niwibe/buddy Doc: http://niwibe.github.io/buddy/ Any improvements, examples or more documentation are welcome!
