@richiardiandrea I was looking for an easy way to be able to select a buffer or an expression, evaluate it and have it run in another emacs window.

Can Schema be used in Lumo? It produces a whole bunch of warnings:

@metametadata never tried schema with lumo

lumo -D prismatic/schema:1.1.6 myscript.cljs ?

I see

I hoped maybe there's already an easier way to specify deps (e.g. smt. akin to packages.json)

there’s no story for downloading maven deps if that’s what you’re asking

right

well, I looked at Calvin and cljs/tool

you can totally have a build.boot file

with your dependencies

and do boot show -c > cp.txt

right, or lein cp

then lumo -c $(cat cp.txt) ...

yeah

okay. And do you have any suspicions about why Schema would not work with Lumo?..

hm, I guess I don't quite understand how the compilation is different in Lumo vs. "traditional" lein-cljsbuild-based one

uh

the problem is macros

in JVM ClojureScript macros are expanded in Clojure

in Lumo there’s no Java

macros are expanded in ClojureScript

@metametadata so as soon as you use some java library, you’re done

haha, alright, now I get it

so macros should be written in "self-hosted" style?

okay I'll google that. And have you tried core.spec with Lumo?

I've tried it. Good news is that at least it doesn't barf on requiring the ns:

cljs.user=> (require '[clojure.spec.alpha :as s])
nil

yeah, spec should work great

we put a lot of effort making spec self-host compatible

that's awesome, then I'll probably use it instead of Schema. Thank you!

cool
