A very cool of use of core.logic, look forward to seeing where it goes :) On Wed, May 29, 2013 at 11:10 AM, Maik Schünemann wrote: > Hello, > I am glad to announce that my proposal got accepted for google summer of > code. > I am doing the algebraic expression project idea which could lay the >

A core.logic cheatsheet would be a fantastic resource. I'd also welcome help in generating the basic doc pages. On Wed, May 29, 2013 at 1:08 PM, Benjamin Peter wrote: > Hello, > > I am currently trying to find my way to using clojure core logic, watching > some videos, reading tutorials and tryi

Good catch - please file a ticket here http://dev.clojure.org/jira/browse/MATCH. Please attach any work-in-progress patch you may have there and I'll review. Before I can apply any work you've done you need to send in your Contributor Agreement (CA) - http://clojure.org/contributing Thanks, David

Re: core.match -- adding extractors?

I've looked at extractors a little bit, but I would need to investigate further. Does this offer any more power than supporting arbitrary function application in patterns? Also, I'm unlikely to dive into any feature addition related issues until all these pressing bugs in JIRA are squashed. On T

ANN: core.match 0.2.0-beta2

At long last I've come around to overhauling core.match. Changes/Fixes/Enhancements are documented here: http://github.com/clojure/core.match/blob/master/CHANGES.md core.match should no longer have AOT issues as far as I know and many long outstanding bugs have been eliminated. The ClojureScript

Re: Why does peek on a seq of vector fail?

Calling seq on vector returns a sequence which is no longer a vector. The docstring is pretty specific about which types it's supposed to work on. clojure.core/peek ([coll]) For a list or queue, same as first, for a vector, same as, but much more efficient than, last. If the collection is empt

Re: (clojure 1.5.1) Weird performance results when using let versus def for variable

Using `def` like that is simply incorrect. `def` should always be at the top level unlike say Scheme. I would first remove all internal defs and then rerun your benchmarks. On Fri, Jun 21, 2013 at 8:36 AM, Colin Yates wrote: > Hi all, > > I am doing some (naive and trivial) performance tests b
