Is anybody here using Heroku to host a backend clojure app?

i’m running some prototypes on heroku

@hmaurer

anyone here using https://news.ycombinator.com/item?id=15600928 ? (closh, the clojure shell)

not yet, but plan to

startup time seems to be an issue

does that impact shell forking or just initial startup?

do you pay that startup cost once or repeatedly

I don't think closh supports forking yet?

oh. i thought shells had to fork just intrinsically.

tbh it's barely a shell

@bronsa what sort of startup time are you getting with it? Is it particularly slow?

lumo is pretty fast at startup.

i'm getting 0.8s startup

i noticed wide variance in lumo startup between macos/linux and different nodejs versions last i tested. like 800ms here, < 100 ms there. unhelpfully, i can't remember what was fastest/slowest tho. and i never found out why

where can we report bugs in clojure docs? found a broken source link

@dpsutton Which docs? if http://Clojure.org: https://github.com/clojure/clojure-site

https://clojuredocs.org/clojure.core/set!

the source link on that is broken

https://github.com/zk/clojuredocs

Hmm, the source links works for me. it just takes some time to load the whole file

ah yeah. it's set! https://clojuredocs.org/clojure.core/set!

oh it's dropping the ! from the url parsing haha

add the ! at the end

and the malformed link for source: https://github.com/clojure/clojure/blob/clojure-1.9.0-alpha14/src/clj/#L

set! is a special form so it is not defined in core.clj, but in clojure.lang.Compiler: https://github.com/clojure/clojure/blob/clojure-1.9.0-alpha14/src/jvm/clojure/lang/Compiler.java#L596, probably it would make sense to just hide the source link if no location can be found

ah ok. thanks for looking over that with me then. is there a place i can suggest that or are you in a position to do that?

Clojuredocs github repo should be good place to open an issue, I linked it few messages ago
