What is the reason for the dropping buffer not supporting size 0?
Why the most trivial option of "no buffering" is not supported out of the box
by core.async?

Hey Tzach,
If I understand what you're trying to do, you want something like this:
[ :uint32
:ubyte ;; or bit-seq, depending
(delimited-block (prefix uint24 #(- % 5) #(+ % 5))) ]
And then you'll need to parse the final block separately. I've left
defining the uint24 as an exercise for the
I'm not sure whether this counts as an answer. I put this definition in a
file that my leiningen project loads by default:
(defn set-pprint-width
"Sets width for pretty-printing with pprint and pp."
[cols]
(alter-var-root
#'clojure.pprint/*print-right-margin*
(constantly cols))
Hi,
Is it possible to change default value of
clojure.pprint/*print-right-margin* var and alikes in one place. I use
pprint in many places and would like to avoid wrapping it with "binding" in
every case.
Thanks,
Andy

If you want to boost performance a bit just memoize the conversion
functions. Memoize makes you vurnable to exploits though, better use
something with WeakRefs if you convert anything from untrusted sources (eg.
guava CacheBuilder). But given your usecase this will probably be the
biggest gain,
Btw, if you own the defrecord, extend a protocol to it directly in its
definition, rather than in a separate extend or extend-protocol form.
Doing it inline makes the record implement the protocol's backing
interface, which will be much more efficient. (If it's not your record you
don't really
On further investigation, it looks like you're suffering from

TL;DR: If you wait for that lein-ring pull to get merged, you can upgrade

current alpha doesn't have a fix). If you want your problem to go away

lein-ring uses AOT compilation to build war files. AOT compilation in
clojure is, well, problematic sometimes. Fortunately it can almost always
be avoided using clever indirection.
For example: https://github.com/pdenhaan/extend-test/pull/1 builds a war
that works =)

Thanks for this, Andy.
I see it uses postwalk and recursion for nested maps, so it will eventually
blow up the stack. Probably faster than a zipper though.
Also, for changing case it uses a custom split and join instead of regex, a
very interesting approach.
I won't be using it directly though
I have not used it, but from the docs it appears there is at least some
overlap with this library:
https://github.com/qerub/camel-snake-kebab
It mentions in its docs that it avoids using regex's.

Hi,
I've written a small library (1 ns, 100 lines) to transform nested maps
from "dash-case" keys to "camelCase" keys and back.
The original use case was taking MySQL records that use camelCase field
names and convert them to dash-case so they don't stick out like a sore
thumb in my code. Simi

There is also vertx.io with the clojure module.

Hi all,
I want to parse a stream of text which comes from a java.io.Reader with
https://github.com/Engelberg/instaparse.
But the stream of text will only start with what can be parsed by my
grammar. The rest of the text stream must be
consumed/parsed with some other grammar. I know of instpars
I'm a relative newcomer to Clojure, and I'm puzzled by problems I have
using extend in a webapp. Any help would be hugely appreciated.
My use case is basically this:
(defrecord FooRecord [msg])
(defprotocol FooProtocol
(bar [foo] "to use with extend-type"))
(extend FooRecord
FooProtocol
+1 - I think we are saying the same thing (not sure if you meant to
reply to me?)

I think the answer to questions like this is that you are testing the wrong
thing, or more correctly you are writing incomplete tests.
In your example, you stubbed out check-pw. But calling check-pw has a
contract, a contract that (at the moment) only exists in your head, but a
contract none-the-l
Fixed in master thanks to Michal Marczyk!

I don't think there is an easy answer here, and note that this is a problem
generic to mocking (i.e. not clojure or midje specific).
The usual advice applies though:
- do you really need to mock? Unit testing is about the coarseness of
granularity which is defined more by cohesion and abstract
Akos,
that is exactly the kind of problem I'm talking about! Right down to the
detail about stopping work and returning to the project later, and seeing
all the tests pass!

I'd suggest taking a look at the alts! function in core.async (or the
equivalent alt! macro).

I am also working on improving the backpressure story on all fronts at the

Some jetty adapters also supports the async interface using core.async:
