Re: [ANN] expresso 0.1.0 released
Hi David, The core of expresso wouldn't be much work to port to clojurescript. The rule based translator is built on top of core.logic, so porting that should be straightforward. Also the manipulation routines are very much purely algorithmic so should work without much trouble in clojurescript. There are two things which need to be resolved, though: 1.) what execution engine: expresso is very close to core.matrix and uses its functions to execute the expressions and it's function names and semantics for the encoded expressions. 2.) compiling optimized expressions to functions at runtime: In clojure I managed to compile optimized expressions to optimized code at runtime through a code-emitting protocol and a call to eval to create the function. Without eval in clojurescript this couldn't be done easily. With compile-time constant expressions this could be made to work with a macro. At runtime there would still be the normal evaluate function which however traverses the whole expression tree. So if anyone knows a good execution engine for expresso in clojurescript or has thoughts about the compiling issue please post! I think it would be a good showcase for clojurescript to bring symbolic manipulation cababilities including solving equations etc to the browser.

Re: ClojureScript: Keyword Breaking Change Around the Corner
For #2, we can't intern the keywords like Clojure does on the JVM because JavaScript does not provide weak references. If we interned dynamically created keywords, then we'd have an exploitable memory leak. This may actually be a non-issue for Browser Environments since you would not exploit your users and your users would only be able to exploit their own browsers unless you somehow allow them to send arbitrary data to each other (which you should never do anyways). So interning might still be an option for browser targetted JS, even without weak references (IMHO).

At runtime, evaluation behaves like an interpreter looking up the expression symbols into the user-specified environment (collection of maps) to find their values, so the performance takes a hit there. The overhead is directly proportional to the depth of the expression and number of symbols used. If you can precompile the dependency functions (using code generation or macros) and use them in the environment instead of passing a large expression to evaluate, that should minimize the performance overhead. I will be happy to answer any specific questions or go into detail, please feel free to ask. The fn expression (via the evaluator) doesn't support meta-info, pre-conditions etc now but the essential functionality should work.

Java Metadata Wrapper
I've noticed that, when doing a lot of Java interop, it's impossible to attach metadata to most Java objects, since they don't implement the IMeta interface. A workaround for this would be to do something like put every Java object in a single-element list and attach metadata to the list, but this is annoying. Would it be possible (or even useful) to create some kind of generic IMeta structure that can wrap other Java objects and have them act like normal, except for the added metadata (or even other Clojure-esque features)? -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] core.typed 0.2.0 - Production Ready
Sorry for a late reply to the thread. This release is pretty cool. I
haven't been following the development too closely, so I have two questions:
1. Is ClojureScript/ClojureCLR supported by core.typed? Or, is it planned?
2. Is there a Leiningen plugin that can help run the type checks from the
command line?

Hi,
After 10 months and 26 0.1.x releases of transitioning core.typed from an
ambitious student project, I am finally comfortable recommending core.typed
for production use.
Production Ready
My interpretation of production ready in this context is:
- core.typed can *find bugs* in real code
- core.typed will *not slow down* your existing code by loading
a large library at production. (core.typed does introduce an extra
identity-like
function call at type annotations, I assume this is a candidate for
optimisation via
HotSpot)
- A basic *tutorial*, API docs and example project exist
- core.typed is *currently used in production* with success (at CircleCI
for several months)
- The core type checking API is mostly *stable*, with only very
minor removals/breaking changes in the last few months.
There are several outstanding issues, but I am satisfied that core.typed
can bring real utility to real programs *today* and with *no
production-time drawbacks*, thus this release.
How to get started
Leiningen dep:
[org.clojure/core.typed 0.2.0]

ANN Introducing EEP, a young [event] stream processing library
On behalf of the ClojureWerkz team [1], I'm happy to announce our new project, EEP (for Embedded Event Processing). Read the announcement: http://blog.clojurewerkz.org/blog/2013/08/29/stream-processing-with-eep/ The library is young and definitely could use better documentation but it's mature enough to start gathering feedback from the rest of the community. Please give it a try. There will be a couple more exiciting announcements from ClojureWerkz in the next few weeks. So watch this space. I'd like to thank Alex (http://twitter.com/ifesdjeen) and his dog Huskell (https://twitter.com/huskelldog) for driving this project. 1. http://clojurewerkz.org -- MK http://github.com/michaelklishin http://twitter.com/michaelklishin -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: ANN: clj-tuple, efficient small collections
I've updated the library so tuples behave like vectors, rather than lists. The macros have gotten kind of elephantine, but since I've already added every conceivable Clojure interface at least they won't get any bigger. If there are any lingering gaps, though, please let me know.

Re: [ANN] core.typed 0.2.0 - Production Ready
Hi Shantanu,
CLJS support is planned but not current plans to work on CLR myself.
No leiningen plugins yet, FWIW I tend to add type checks to my unit tests
like:
(is (check-ns 'my.ns))
Thanks,
Ambrose

Sorry for a late reply to the thread. This release is pretty cool. I
haven't been following the development too closely, so I have two questions:
1. Is ClojureScript/ClojureCLR supported by core.typed? Or, is it planned?
2. Is there a Leiningen plugin that can help run the type checks from the
command line?

Hi,
After 10 months and 26 0.1.x releases of transitioning core.typed from
an ambitious student project, I am finally comfortable recommending
core.typed for production use.
Production Ready
My interpretation of production ready in this context is:
- core.typed can *find bugs* in real code
- core.typed will *not slow down* your existing code by loading
a large library at production. (core.typed does introduce an extra
identity-like
function call at type annotations, I assume this is a candidate for
optimisation via
HotSpot)
- A basic *tutorial*, API docs and example project exist
- core.typed is *currently used in production* with success (at
CircleCI for several months)
- The core type checking API is mostly *stable*, with only very
minor removals/breaking changes in the last few months.
There are several outstanding issues, but I am satisfied that core.typed
can bring real utility to real programs *today* and with *no
production-time drawbacks*, thus this release.
How to get started
Leiningen dep:
[org.clojure/core.typed 0.2.0]
...; for very recent releases:repositories {sonatype-oss-public
https://oss.sonatype.org/**content/groups/public/
https://oss.sonatype.org/content/groups/public/}
If you like following tutorials try the user/types guide. If you just
want to get your hands on some typed code, see the Example project.

[ANN] Pedestal 0.2.0 has been released
Hey Folks, We've just released 0.2.0 versions of the Pedestal libraries. This is a big one, with revamped templates for both pedestal-app and pedestal-service applications. The biggest change is that developer tooling now lives in *-tools libraries, cleaning up generated projects and making it easier for us to incrementally improve that tooling in the future. You'll also find that pedestal-service now uses Cheshire for JSON reading/writing. All this and more is documented in the 0.2.0 Release Notes. Kudos to everyone that contributed to this release.

Re: ANN Introducing EEP, a young [event] stream processing library
Looks very interesting, thanks for sharing! Could you summarise how this fits in the ecosystem relative to Storm, Aleph etc? When should EEP be the most appropriate choice?

Re: Java Metadata Wrapper
It would be better, I think, if metadata was attachable via a protocol rather than than a wrapper: then you could just extend the protocol to any arbitrary Java class. Wrappers are a pain to make work because of wrapping / unwrapping and protocols also have the advantage of being very efficient. I've wanted a similar feature with respect to seq as well (a protocol for things that can be treated as sequences) On Saturday, 31 August 2013 03:16:26 UTC+8, JvJ wrote: I've noticed that, when doing a lot of Java interop, it's impossible to attach metadata to most Java objects, since they don't implement the IMeta interface.

Re: Detecting login and logout using friend
I had to do this again in another project so I tried Chas' suggestion. It
is much simpler than my earlier solution.
For anyone else doing this in the future, here's how you can write it:
(defn check-workflow-result
check if the response contains and auth-map. If so, notify the event bus
[request response]
(when (friend/auth? response)
(event-bus/fire :session-start
{:user-agent (get-in request [:headers user-agent])
:ip-address (:remote-addr request)
})))
(defn wrap [f]
(fn [request]
(let [response (f request)]
(check-workflow-result request response)
response)))
(def friend-interceptor
(friend-authenticate-interceptor
{:allow-anon? true
:unauthorized-handler (fn [request] (ring-resp/redirect /thanks))
:workflows [(wrap
(oauth2/workflow
{:credential-fn get-friend-creds
:login-uri /login
:client-config (authentication/get-oauth-config)
:uri-config authentication/uri-config-sfdc
}))]}))
