Re: clojure.math.combinatorics/combinations throws exception on n=1

[Alex Miller]

I think this could be corrected by calling seq on the incoming coll (on the 
last line of the definition) and that would be in line with the rest of the 
seq functions in "seq"-ing their arg.

This is kind of a degenerate case of course - sets are always distinct so 
(distinct ) should be the same result as (seq ), but it will be 
slower because it's doing lots of unnecessary work. I suppose it's possible 
distinct is not supporting sets intentionally for this reason but don't 
know.

[ANN] Quil 2.4.0 and improved live editor

[Nikita Beloglazov]

Happy to announce Quil 2.4.0 release.

Quil is a Clojure/ClojureScript library for creating interactive drawings
and animations.

The release available on clojars: https://clojars.org/quil. List of changes:

   - Updated cheatsheet
   .
   Thanks to @SevereOverfl0w .
   - Added support for some new processing functions: pixel-density,
   display-density, clip, no-clip, key-modifiers.
   - Fixes: #170 , #179
   .
   - Upgraded to ProcessingJS 1.4.16 and Processing 3.0.2.
   - Drop support of Clojure 1.6.0.
   - Migrated from cljx to cljc and various refactorings to make Quil
   compile with self-hosted cljs.

Documentation on http://quil.info has been updated as well.

*Live editor*

Editor  on quil.info was revamped and
migrated to self-hosted ClojureScript! That means that now you can evaluate
code ~instantly in browser and even reevaluate parts of code. Editor
provides following features:


   - full client-side compilation including macros from quil.core;
   - partial evaluation: use Ctrl+Enter to evaluate selected code or form
   under cursor
   - warning and error messages;
   - easy sketch sharing via URL;

Feedback and bug reports are welcome! Feel free to reply to this thread or
file a bug in Quil repo .


Happy hacking!

Nikita

Re: clojure.math.combinatorics/combinations throws exception on n=1

[Mark Engelberg]

Looking at the source for distinct, the reason it fails is because it tries
to destructure the set as a seq, and sets can't be destructured in this way.

A lot of people think that (let [[f & r] coll] ...) is the same as (let [f
(first coll), r (rest coll)]...), but they are not the same, because first
and rest implicitly call seq, but destructuring does not.

Perhaps this is an oversight in the clojure.core/distinct source.  It's
certainly an easy enough change (just change the destructuring line, or
call seq on coll, or do something polymorphic for the case of sets) and
then it would support sets as well.  I couldn't speak to that.

[ANN] schema-generators 0.1.0 (now with ClojureScript!)

[Jason Wolfe]

We've released schema-generators 0.1.0, which includes ClojureScript 
support via cljc:

https://github.com/plumatic/schema-generators

This library allows you to generate test data from most plumatic/schemas 
out of the box, as well as automatically "complete" partial datums -- which 
can both be very useful in different testing scenarios.  Please note the 
the corresponding functionality is now deprecated in the main schema 
project.

Big thanks to Milton Reder and others who helped with this release!   And 
on this note, *schema, plumbing, and our other libraries are now a 
completely volunteer effort, with no commercial support*.  Any help the 
community can provide in triaging issues, fixing bugs, etc would be much 
appreciated -- especially on the ClojureScript side of things.  If you're 
interested in helping out, please let me know and I'm happy to provide 
suggestions for how to get started.  

Have fun, and please let us know your feedback!  

-Jason

Protocols in another namespace, retract-type possible ?

[Niels van Klaveren]

In a project using clojure.java.jmx, I was extending it's Destract protocol 
object->data function  to transform more of the JMX data structures 
returned from calls or metadata queries into plain clojure data structures. 
When I was done with the individual data structures, it should have been 
possible to do a (walk/prewalk jmx/objects->data (jmx/operations 
"java.lang:type=Threading")).

However, in the Destract protocol there's an implementation of the 
objects->data function for the type clojure.lang.Associative that would 
mean maps would be processed incorrectly. I could add an implementation for 
clojure.lang.IPersistentMap in my namespace, but since 
clojure.lang.Associative is also an interface for maps this would not work, 
and I ended up having to fork clojure.java.jmx because of it. If there 
would be  a way to retract a protocol for a type within another namespace I 
wouldn't have had to. Is there such a way, or would it even be feasible to 
implement something like it?

Re: clojure.math.combinatorics/combinations throws exception on n=1

[Erik Assum]

Interesting that set doesn't implement distinct. It should be a pretty straight 
forward implementation.
