like (aget a "b") that generates a["b], how do I generate a["b"](c) with js interop?

in :advanced mode the property name might be uglified, but I don't want it to

@polymeris: there is https://github.com/untangled-web/untangled which works on top of Om.next and should make implementing some functionality easier.

Hi, I’m working on my first Clojure project, a consumer of RabbitMQ messages. I’ve created the project with leiningen but I used the single core.clj file to put everything. I’m cleaning this up and creating several files (smtp.clj, mq.clj, sms.clj, …) that I load in the main core.clj. Some functions (that are not in the same files) need the same clojars (like clj-http, log, …) what is the recommended way to load those commun lib ?

This is what the (ns yourproject.core (:require [clj-http :as http] [log :as l] …)) is for

@jswart great so loading them in the core makes them available to all the files loaded with (load « … ») ?

Hmm, so if you are writing the files you don’t want to use load.

Load is for the REPL mostly.

I’m kinda following this recommendation: http://stackoverflow.com/questions/4690758/splitting-a-clojure-namespace-over-multiple-files

Hmm, I would give this a read http://www.braveclojure.com/organization/

In general @lucj06 clojure has changed enough that any comment from > 1-2 years ago is likely not a best practice. Chouser is a smart dude but in general that is not the “state of the art” in clojure.

use would be considered a “worst practice” at this point.

I recommend reading all of braveclojure to get started. It is a super fast read but super packed with knowledge.

and probably the fastest way to go from 0 -> understanding clojure

yep, I’m reading it

oh cool

but I should probably reread all the namespace and organisation stuff

Yeah that part is unusual when you come from other languages

b/c the REPL and writing code are a bit different

thanks for your tips of requiring within the ns

you do different things

yeah no problem

you can use require too when you are working in a REPL

I’ll give a closer look to « use » also

lein repl and then (require ‘[myproject.core :as c]) then (c/my-fn 123)

got it

I would mostly avoid use. I write clojure for my job and I almost never use it.

I do what I just typed

or

I do the above and then: (in-ns ‘myproject.core)

to achieve a similar effect

just to be sure. Let’s say I have core.clj and smtp.clj

at the top of smtp.clj I use (in-ns ‘myproj.core)

and in core.clj I use (load « smtp »)

the load part is wrong ?

So when you are writing the files themselves, in your editor you would do this: (one sec I’m making a big snippet to paste in)

thanks. in term of file structure do you have project/core project/smtp and project/db ?

yeah that part sort of depends

basically src/myproject/core.clj -> project.core and src/myproject/db/core.clj would be project.db.core the NS macro just looks at the directory structure

that is honeslty something I usually forget and just mess with until it works

got it ! (I usually do the same :) )

thanks a lot for your help, that’s great.

So, I guess this has been asked many times, but I see that lists and vectors are pretty much similar - where would one favour lists over vectors?

(and perhaps why one is a sequence and the other is not?)

@dharrigan: http://stackoverflow.com/questions/11504236/as-a-data-container-what-are-the-main-differences-between-vector-and-list

vectors allow random access, lists only sequential

reading...

and other differences

so a vector is similar to an array/List in java, whereas a list is more akin to a LinkedList.

yes

coolio. ta.

(I think, I’m not big on Java)

Those Clojure Koans are pretty nifty
