Re: Modelling in Clojure
To their a wrench in the works, keywords are functions that look themselves up in a map.

Emacs Utilities
Hi, I’ve written a collection of Emacs Utilities which includes a project manager, a persistent file history list, a persistent position history list, a popup menu listing of a file’s definitions. Clojure documentation support, Common Lisp documentation support and a window management utility. Together with a Cider Repl, this code provides a lightweight, but very powerful Clojure IDE. There is a demonstration video here: www.clairvaux.org/downloads/Emacs-Utilities.mp4 And the code is available here: www.clairvaux.org/downloads/emacs-utilities.zip — Glenn -- You received this message because you are subscribed to the Google Groups Clojure group.

Question about test.check, and knossos
Hi All, Lately I've been exploring the world introduced to me by watching the John Hughes' quickcheck video from clojure west. Awesome stuff! Eventually I found the testing for fun and profit[1] paper which left me wanting to test my apps using a model based system like the paper describes. It looks like test-check-knossos[2] takes a stab at applying knossos[3] to this problem. However the examples in that repo don't capture the the aspect of using state to generate test commands to be executed against the system. It's just a random stream of :take/:reset operations whereas the registry example in the paper seems to require that the function which generates the sequence of test commands has access to the state of the system under test at the start of each command. So is there a missing clojure library here? Is anybody working on something that allows this style of model testing? If not, would it make sense for someone writing one to leverage knossos in any way?

Invalidating a session for a given user
Hi, I wonder if it's possible to invalidate a ring session for a given arbitrary user (not the logged in one)? Sometimes, when applying administrative tasks regarding user management in a web application it might be useful to have the user to relog. Another posiibility might be to be able to update the session of an user, but I am not sure if this is considered secure, or how it might be done at all.

Cheers, Andy [1]: http://people.inf.elte.hu/center/fulltext.pdf [2]: https://github.com/philandstuff/test-check-knossos [3]: https://github.com/aphyr/knossos I've begun to work on such a tool not long ago. Thomas Arts, who gave a talk at our local FP user group meetup [mλ], inspired me to try out the approach you're describing in Clojure. After some experiments I got the library to a state where it could generate test cases for java.util.HashSet. I looked for prior art in the area of concurrency and detection of race conditions. That's when I discovered Philip Potter's Knossos-based approach [pp]. I find it very interesting but I haven't yet had time to try it out. It'd be great to have it integrated, though. I demonstrated the tentative API in [gist], where some simple properties of HashSet and Clojure vector are checked. The gist also shows how an exemplary failure looks, including shrinking. I'll try to get the implementation to a reasonable state and push it to GitHub soon. Feedback is very welcome!

Re: Invalidating a session for a given user
Surely the same principle applies? Initiate the memory session with an atom, then write a function to remove sessions from the atom that match specific criteria.

[ANN] Immutant 2.0.0-alpha2
We released Immutant 2.0.0-alpha2 today, which includes support for distributed transactions, a simplified messaging API, and other changes. For full details, see http://immutant.org/news/2014/10/23/announcing-2-alpha2/. With 2.0.0, Immutant has evolved from an application server for Clojure to an integrated suite of Clojure libraries for web, messaging, scheduling, transactions, and caching. And though they are now fully-functional embedded within your app, they each become automatically enhanced (session replication, load-balanced message distribution, linearly scalable caches, HA singleton jobs and daemons) when deployed to a WildFly cluster. 2.0.0 has a much smaller footprint, a very fast Undertow web server, a more permissive Apache license, and hopefully cleaner API's. - Toby -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] thi.ng/crypto - GPG/OpenPGP keypair generation, file/stream encryption helpers
W00t! Thanks for the heads up! That looks far more fully featured indeed... bookmarked! Btw.

Retrieving the namespace an expression in compiled in
I have some code that looks like this: (ns foo.bar.endpoint.example (:require [compojure.core :refer [routes GET]] [duct.util.resource :as resource])) (defn endpoint [config] (routes (GET / [] (resource/url foo/bar/endpoint/example/index.html In this case the resource/url function acts the same as clojure.java.io/resource. The problem is that I'd like to remove the repetition, so I extended resource/url with the ability to derive the resource path from a namespace object. (defn endpoint [config] (routes (GET / [] (resource/url *ns* index.html The problem with this approach is that the *ns* binding changes, and I want to fix it at compile time. I could write: (def this-ns *ns*) (defn endpoint [config] (routes (GET / [] (resource/url this-ns index.html But it's very tempting to use the eval reader form: (defn endpoint [config] (routes (GET / [] #=(resource/url *ns* index.html Or a macro: (defn endpoint [config] (routes (GET / [] (resource/url (this-ns) index.html Alternatively, I could do something with a quoted symbol: (defn endpoint [config] (routes (GET / [] (resource/url `index .html Or a keyword: (defn endpoint [config] (routes (GET / [] (resource/url ::index .html What does everything think is the best solution? I must admit I'm tempted to use the eval reader, as it makes it very explicit as to what's happening, while at the same time being very concise. On the other hand, the eval reader isn't often used, and isn't actually documented in the reader docs, just in the *read-eval* docs. - James -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] fast-zip 0.5.0 now with ClojureScript support
