Hi!
I’m glad to announce my new library, DataScript.
It’s an open-source, from-the-scratch implementation of in-memory immutable
database aimed at ClojureScript with API and data model designed after
Datomic. Full-featured Datalog queries included.
Library is here:
Hi Nikita
Can you explain what you mean from the limitations on the GitHub Readme?
This:
No history support, though history can be implemented on top of immutable
DB values
Seems to contradict:
Immutability simplifies things even in single-threaded browser
environment. Keep track of

I do as Dan does. Sometimes I prefer to use defrecord instead of a regular map,
e.g. when there are mutable values involved. In such a case I always define a
constructor for the record instances.

Hi Daniel,
First sentence was written from Datomic standpoint. In Datomic, all history is
kept in the database ref. Given ref to an immutable DB, you can rewind back to
any point in time. I can guess that each DB value consist of indexes to
current, latest state + append-only history log.
This morning I'm happy to announce the latest version of core.async:
0.1.295.0-9ea6ef-alpha
No new features to announce, but there are significant under-the-hood
changes:
ClojureScript changes -
* Fixed a bug where pending puts were not moved into buffer as items were
taken from the buffer
I know I used to be able to access clojuredocs from a repl, as in
(user/clojuredocs deftype)
but now I get
Loading clojuredocs-client...
Warning: Could not load the ClojureDocs client, so `clojuredocs` will
be unavailable
Details: #FileNotFoundException
I see that behavior, too, with Leiningen 2.3.4.
It looks like this commit probably caused the change in behavior. I am not
sure of the motivation for this change to Leiningen:

The clojuredocs macro still works in Leiningen 2.3.3, which there should be
a way to go back to if you wish.
I just checked on my system, and the Leiningen shell script for 2.3.3 and
2.3.4 seems to differ only in this line:
export LEIN_VERSION=2.3.3
You can edit that line's version to 2.3.3 and

I've based a ton of work on keywords where the second character is numeric.

The work is based on *reliance* on the definitions in the readers page. I

BTW, is there an issue tracker? Maybe I'm doing something wrong, but I'm

Hi,
There has been one thing bugging me for a long time that seems worth it to
fix, and I was wondering if anyone else has had the same problem. I have
enjoyed using Clojure's REPL and embracing a Clojure-style data model for
my app, where everything is a glorified map or vector and there are
Hmm... Ok I read
http://sritchie.github.io/2014/01/17/api-authentication-with-liberator-and-friend/

I'll add it later. The part explaining the authentication explains a lot
but still couldn't figure out how to implement

The most interesting thing I've learned from this release is just how
lenient old releases were in the face of erroneous code, of which I appear
to have had rather a lot. :)
That said, I have found at least one behavior I'm not able to understand.
This works perfectly with the new core.async:
You might be interested in this ticket
(http://dev.clojure.org/jira/browse/CLJ-1278) of which this is perhaps one
special case.
I don't know that I necessarily would want the equality semantics; at least
in the case of impure functions the equality does not hold.

feedback, I'll create a new release. Should be out sometime in the next few
I don't know if this is considered good Clojure, but you could define a
print-method within a macro to set up the normal string representation for
the partial function:
(defmacro partial* [fname arg0 args]
`(let [pf# (partial ~fname ~arg0 ~@args)
cpf# (class pf#)]
(defmethod
That's not going to work, all the return classes of partial are the same
class.

I guess I don't understand the problem, or what is meant by different
classes. A counter-example would be helpful.
Further transcript using the macro:
(def p6 (partial* + 1 2 3))
#'user/p6
user= (class p6)
clojure.core$partial$fn__4194
user= (def p10 (partial* + 1 2 3 4))

Ah, I think I was mistaken in a detail, but generally correct. Try it with
two partials of the same arity.

Got it. The macro, as is, will displace the print method for the same arity.

Hi all,
I'm working on an API at the moment, and I'm balancing whether to use
inline keyword args which I would destructure in the functions, or whether
to just pass an explicit params map as the last parameter. Comparison of
the two options in case I'm not explaining myself well:
Kwargs:
Is there a list somewhere of the various lein templates?
I'm especially interested in comparing the templates for clojure web
development and/or clojurescript.
The few I've sampled exhibit a wide variety of philosophies in terms of
whether to be minimalist or batteries-included (and which
Hi!
I have the same doubt!

Seesaw looks nice, but in retrospect I would use explicit maps if I had it
to do all over again for exactly the reasons you mention. These days, I
always use explicit maps for options.

If it's more than a few parameters, I prefer maps.. It enables the

Since these projects have to be named lein-template, you can actually get
the full list via `lein search`, provided you don't need to search
non-standard/private repositories.
I bumped my :user profile's :search-page-size to 1000, and got this when I
ran `lein search lein-template`:
