Clojurians Log v2

FYI, ClojureScript also has (cljs.core/random-uuid)

But Clojure does not have this function in clojure.core

For Clojure:

(java.util.UUID/randomUUID)

In something we call an observer in our app, we trigger a re-frame subscription to happen only for the side-effect of having the rest of the code run. I’m hunting a bug in there but started to wonder about wether the way we do this thing could potentially stop working. So it happens in a let box:

...
(let [...
      _ @(rf/subscribe [:something])
      ... ]
...

let -bound variables aren’t DCE’d by the compiler (at least I would be very very surprised if they were). I’d try to verify that the subscription is being updated, maybe put a prn in the component to show you every time a render occurs, and in the subscription handler to print out the new value. Also be sure that you’re deref’ing the subscription inside of the Reagent render function, not like (let [_ @(rf/subscribe ,,,)] (fn [props] ,,,))

> Anyone knows if that could happen? It could not. It has side-effects.

It has nothing to do where the line is exactly - in let, in an unused def, within the let body just as a free line, anywhere else. It won't be removed.

Awesome. I know it is working, so no worries there. I just wanted to know that it will keep working. 😃

This is purely about aesthethics but I don't suppose there is a way to turn off that sort of warnings? The fact that the compiler munges a name that is a reserved keyword:

compiler- warning: Namespace helins.void contains a reserved JavaScript keyword, the corresponding Google Closure namespace will be munged to helins.void$

@adam678 :warnings {:munged-namespace false} in the compiler options

@thheller Thanks! This is rather safe, isn't it? It seems important only for accessing it directly from JS

yes

Salut. I'm using shadow-cljs + refactor-nrepl. cljr-clean-ns in cljr-refactor.el then cleans up the namespace's requirements, but that doesn't play nicely with npm imports (https://github.com/clojure-emacs/clj-refactor.el/issues/476). I saw that that lib has configuration :prune-ns-form (https://github.com/clojure-emacs/refactor-nrepl#configuration), which disables the pruning entirely. I've built refactor-nrepl locally with the default set to false, included it via deps.edn to verify this. Is there a simpler way to set that configuration? Either via shadow-cljs.edn or some separate config file? I dug through a few documentations, but I couldn't figure it out. Maybe there's a general way to do this that I don't know?

is it possible to access clojurescript vars in a clojure macro?
