Clojurians Log v2

did anyone upgrade to big sur yet? I'd be curious if this issue still exist in the final release. https://github.com/thheller/shadow-cljs/issues/767

apologies if theres an easy reachable answer to this (I wasn’t able to find it) — is there a way to reference an environment variable in the dev-http block of shadow-cljs.edn?

todo what exactly?

e.g. i want to be able to do something like:

{:nrepl    {:port 8777},
 :dev-http {8280 {:root             "resources/public",
                  :proxy-predicate  foo.bar/proxy-predicate,
                  :push-state/index "baz/index.html",
                  :proxy-url        (or (System/getenv "FOO_BAR_URL") "<https://bat.com/>")}},
...
}
 

#shadow/env ["FOO_BAR_URL" "<https://bat.com/>"] second value is default if env var is not set

https://shadow-cljs.github.io/docs/UsersGuide.html#shadow-env

ah, thank you… i did see that form in your docs, but i thought it had to occur in this block :closure-defines {http://your.app/URL #shadow/env "APP_URL"}`

foolish of me not to try, thanks for the help and love the tool!

yeah works everywhere. not specific to :closure-defines

So if I have cider connected to a shadow project and the repl is warning me `No available JS runtime.` yet jump-to-definition is working, what functionality will I be missing?

https://shadow-cljs.github.io/docs/UsersGuide.html#repl-troubleshooting

many cider operations don't actually require eval so they'll work. everything that does eval will need a runtime.

Ah, ok. Turns out I figured out the issue. Gotta load the right page 🙂

How can I use a local closure-compatible JS lib? Specifying :libs ["../path/to/lib"] and then requiring it as a namespace doesn't seem to work.

just needs to be on the classpath normally

no extra option required afterwards

With (:require ["sjcl/hmac" :as hmac]) I'm getting:

Execution error (AssertionError) at shadow.build.data/add-string-lookup (data.clj:119).
Assert failed: (symbol? sym)

hmm? whats the full stacktrace?

and src/sjcl/hmac.js exists

this is a file with goog.provide?

yes

then it should be (:require [sjcl.hmac :as hmac])

ah ok

does the FS path need to match the goog.provide value?

i.e. goog.provide("foo.bar.baz") need to be in src/foo/bar/baz.js or similar?

ideally yes but it doesn't have to

got it, thanks!

Hi everyone, I just stumbled on shadow.markup (https://github.com/thheller/shadow/wiki/shadow.markup) and thought it looked interesting but it hasn't been updated in 2 years. Is anyone here using it in production and would like to share their experience?
