Re: [ANN] Alia 2.1.1 - Clojure client for cassandra

Another cool feature I forgot to mention: https://github.com/mpenet/alia/blob/master/CHANGELOG.md#200-rc3 execute-chan-buffered: it basically allows you to do a query that would return a huge amount of data, and take advantage of java-driver streaming properties to read that data from a core.a

What is happening in this code?

I am new to Clojure, I am currently at Beginner level. While trying to run small programs, I found that I can load a file having duplicate code. Let me explain it with example. This is the code (ns clojure_begins_19_08_2014.core) (defn first-fn[x] (print x)) (defn first-fn[x] (print "Valu

Re: What is happening in this code?

Clojure is form-oriented so you can think of almost all of its evaluation as sending one form after another to a REPL. In that model of evaluation, you of course want to be able to re-define a symbol an arbitrary amount of times. The serialization of these forms into a file which has other forms i

Re: What is happening in this code?

Repeat several times the magic incantation, dynamic, dynamic, dynamic, :))) Your second definition overrides the first one. Generating a warning when a redefinition occurs appears to me as not practical. In the REPL, you would not like it at all. Add another top level var to enable/disable t

Hi Sam, total noob question coming up (just got started with om beginner tutorial). React components can be used from om apparently (not that i have seen an example of this). So, why is there a need for this library? Is it providing boilerplate around react-bootstrap or doing something more? T

destructuring help: `(let [{:keys [...]} ...]` in a `defn` vs in a `let`

Why is it that although this works: ~~~clojure (defn foo [& args] (let [{:keys [a b]} args] (str a \~ b))) ;;=> #'some-app.core/foo (foo :a 1 :b 2) ;;=> "1~2" ~~~ this does not: ~~~clojure (let [{:keys [a b]} [:a 1 :b 2 :c 3]] (str a \~ b)) ;;=> "~" ~~~ ? And even stranger, *this* *does* work:

Re: destructuring help: `(let [{:keys [...]} ...]` in a `defn` vs in a `let`

The reason is that in the macroexpansion of "let", map-based destructuring has a seq? test which the list passes but the vector doesn't: > (clojure.pprint/pprint (macroexpand-1 '(let [{:keys [a b]} [:a 1]] a))) (let* [map__34214 [:a 1] map__34214 (if (clojure.core/seq? map__34214) (cl

Re: destructuring help: `(let [{:keys [...]} ...]` in a `defn` vs in a `let`

... the other half of the answer being that when you have rest args with (defn foo [& args] ...), "args" is bound to a seq. On Wed, Aug 27, 2014 at 11:27 AM, Ben Wolfson wrote: > The reason is that in the macroexpansion of "let", map-based destructuring > has a seq? test which the list passes b

Re: destructuring help: `(let [{:keys [...]} ...]` in a `defn` vs in a `let`

Apparently a list can be destructured as a map, but a vector cannot. The "& args" syntax returns the result as a list, not a vector. - James On 27 August 2014 19:20, John Gabriele wrote: > Why is it that although this works: > > ~~~clojure > (defn foo [& args] (let [{:keys [a b]} args] (str a
