Yup, juxt is definitely useful, but you need to understand what it is really doing. In your case you have three “functions” and you’re invoking them each with two arguments. Let’s look at those: (:who {:who 1 :when 2} missing) ;; where missing is {:who 4 :what 99} => 1 (:what {:who 1 :when 2} m

juxt uses each of the functions supplied on all of your arguments. The hash-map for :what is because (:what {} :default) returns :default - it's invoking get, which takes an optional "not found" argument. On Sat, Jul 15, 2017 at 8:52 PM wrote: > If I do this: > > ((juxt :who :what :when) {:who 1

I have a feeling that there is a better way to pass log config as implicit argument or implicit context without a global var. Perhaps, I'm being unreasonable, considering that logging itself is not a pure operation that shouldn't do I/O. On Sunday, July 26, 2015 at 1:21:14 AM UTC+9, Shantanu Kumar

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 "js/" in clojurescript?

As noted in the BR, it seems like JS style access after the / was actually intended. Is this behaviour documented somewhere? I see more and more examples in the wild that exploit this feature, it would be great to have it documented somewhere as it can cause confusion. > -- You received this

Re: what is the best way of seeding your database with leiningen

Awesome, Nelson. That's exactly what I want. One minor thing to improve is to isolate these fixture loading codes with app source. I tried to use Leiningen Dev Profile :source-paths. It didn't work. I'll investigate more time into it later. At least for now, I can just put codes in the repl.clj

Re: what is the best way of seeding your database with leiningen

You can use `lein run` to execute a function from your project while avoiding the complexity/distribution of a plugin. In order to seed from a command line I would:: 1. Write a function that can seed the data (like the blog post). 2. Use `lein run -m my.seed.ns/load-fixtures`. This will start a j

Re: What is fn* ?

All functions are eventually created via fn*. If you look for the source code of fn it's a macro that emits a call to fn*. It's done this way so that things like destructuring can be defined in clojure.core (and in Clojure) instead of in Compiler.java (and in java). On Mon, May 26, 2014 at 9:08 A

Hi, How about to port Clojure on top of golang? To get Clojure running on LLVM some of the ideas could be maybe looked from http://julialang.org/. Mic On Thursday, March 28, 2013 6:05:03 AM UTC+10, Joe Graham wrote: > > Hi Group, > Good afternoon I hope everyone is well. I just wanted to reach

Re: What is the right way to create dynamic var in another namespace?

This came up a while back and it appeared that the metadata just reflected whether the var was created with the ^:dynamic annotation. But the meta attribute is an output, so to speak; the info flows from the var declaration to the meta but not the reverse. Maybe it'll remain like that as there'

Re: What is a "state monad binding plan" (referring to code in core.async)

Well, I wrote the code, so I suppose I should comment on it a bit. The ioc_macros use a very loosely defined version of the state-monad. I don't know if the functions/macros follow all the monad laws, and I really don't care, but here's the problem: I needed to be able to track some state while pa

Re: What is the status of Clojure on LLVM or C?

So what I'm gathering (I'm still trying to grok) is that clojure-metal is an approach that somewhat parallels PyPy, except in Clojure, and except that instead of defining a type-inferrable subset RClojure, you instead define an internal DSL via mjolnir that allows you to specify the types withi
