Message:  Could not find namespace: clojure.spec.alpha
Could not find namespace: clojure.spec.alpha

I tried adding https://github.com/clojure/clojurescript as a dependency in my nbb.edn, and then changing

[clojure.spec.alpha :as s]

[cljs.spec.alpha :as s]

@U03RD9KKKRS Currently clojure.spec doesn't work with nbb. However, malli does work

Gotcha. I guess I should've elaborated a little - the actual thing I was trying to accomplish is using Integrant with nbb. Is that a no-go since it makes use of clojure.spec? I assume I can just remove the spec parts from the integrant source code but I didn't know if there was an easier way

Ah right. Well, currently there's probably not an easier way. Babashka runs with a fork of clojure.spec.alpha (minor changes). Perhaps we can have a similar fork for nbb

I see. Yes, I read your post about the babashka/clojure.spec situation. Well okay, I'll have to play around with it a bit today and see what I can come up with

The steps that have been working for me: 1. Make sure clj-kondo is installed 2. Add the same version of promesa nbb uses to deps.edn 3. Open a file in an editor that makes use of clojure-lsp or clj-kondo It should generate the .clj-kondo/* config files which includes the promesa types. Would you be open to an nbb init cmd kind of like package.json that populates some of those things like the deps.edn?

What more should the nbb init command do?

Could generate an nbb.edn file as well, saw some commits earlier for that feature. Thinking near equivalent to npm init

An alternative would maybe be a npm init template or a feature in #babashka-neil to add a clj-kondo config for a library

Oh interesting, didn't realize npm init supported templates

Anyway yeah I think a npm init nbb package would definitely work if it was named create-nbb

% clj-kondo --lint $(clojure -Spath) --dependencies --parallel --copy-configs
No configs copied.
% cat deps.edn                                                               
; This file is only here to assist with editor integration, specifically Cursive on IntelliJ IDEA

; nbb DOES NOT USE THIS FILE - deps are built in (like promesa) or added via npm => package.json

{:paths ["src" "test"]
 :deps  {org.clojure/clojurescript {:mvn/version "1.11.51"}
         funcool/promesa           {:mvn/version "8.0.446"}
         reagent/reagent           {:mvn/version "1.1.0"}}}

is my field report

Do you have a .clj-kondo directory?

in the project

% mkdir .clj-kondo
% clj-kondo --lint $(clojure -Spath) --dependencies --parallel --copy-configs
Configs copied:
- .clj-kondo/funcool/promesa

updated field report

thanks @U04V15CAJ
