Shadow-cljs setup instructions not working

[Risto-Stevcev]

I followed the instructions in the docs to set up vim-iced with shadow-cljs that you outlined in issue #105 , but it's not working.

After following the steps:

1. Generate a test project
   • https://github.com/thheller/shadow-cljs#quick-start
2. Set up shadow-cljs.edn
   • https://liquidz.github.io/vim-iced/vim-iced.html#vim-iced-manual-shadow-cljs
3. Start to watch
   • npx shadow-cljs watch frontend
4. Open app.cljs
   • vim src/main/acme/frontend/app.cljs
5. Connect and start cljs repl
   • :IcedConnect
   • :IcedStartCljsRepl shadow-cljs frontend

Everything was going ok until this step:

:IcedStartCljsRepl shadow-cljs frontend

Where I get:

Missing dependency: refactor-nrepl/refactor-nrepl => 2.5.0
Missing dependency: nrepl/nrepl => 0.7.0
Missing dependency: iced-nrepl/iced-nrepl => 1.0.4
Some dependencies or middlewares are missing. It will be the cause of malfunction.
Do you proceed? (Y/n):

How do I get it to install these? I have this shadow-cljs.edn:

;; shadow-cljs configuration
{:source-paths
 ["src/dev"
  "src/main"
  "src/test"]

 :dependencies [[refactor-nrepl "2.5.0"]
                [cider/cider-nrepl "0.25.3"]
                [iced-nrepl "1.0.4"]]

 :nrepl {:cider false
         :middleware [cider.nrepl/wrap-classpath
                      cider.nrepl/wrap-clojuredocs
                      cider.nrepl/wrap-complete
                      cider.nrepl/wrap-debug
                      cider.nrepl/wrap-format
                      cider.nrepl/wrap-info
                      cider.nrepl/wrap-macroexpand
                      cider.nrepl/wrap-ns
                      cider.nrepl/wrap-out
                      cider.nrepl/wrap-spec
                      cider.nrepl/wrap-test
                      cider.nrepl/wrap-trace
                      cider.nrepl/wrap-undef
                      cider.nrepl/wrap-xref
                      refactor-nrepl.middleware/wrap-refactor
                      iced.nrepl/wrap-iced]}

 :dev-http {8080 "public"}

 :builds
 {:frontend
  {:target :browser
   :modules {:main {:init-fn acme.frontend.app/init}}
   }}}

@Risto-Stevcev Thanks for your reporting!
Which version are you using?

Similar problem is fixed at ver 2.1.4.
https://github.com/liquidz/vim-iced/blob/master/CHANGELOG.adoc#214-2020-08-15
Could you try latest version?

[Risto-Stevcev]

Ah thanks. That fixed that warning about dependencies, but now it just fails sliently and returns :cljs/quit

[liquidz]

Oh, that's strange.
I'll have a look.

[liquidz]

@Risto-Stevcev I confirmed.

https://github.com/liquidz/vim-iced/blob/2.1.6/autoload/iced/nrepl/cljs.vim#L23-L24
:cljs/quit is a display issue and does not affect actual operation. (I'll fix it)

With nvim 0.4.4 and vim 8.2, I could confirm that evaluating :IcedEval (js/alert "foo") will show dialog on browser.

[Risto-Stevcev]

Oh that's odd, it's working now. I'm not sure what happened, sorry about that o_O
Maybe it was caching issue -- I ended up deleting all of the sample apps I was testing out with vim-iced and cider and went through this flow again

[Risto-Stevcev]

Ah I figured out how to reproduce the problem I was running into,

If you follow all of the steps but you don't visit http://localhost:8080/, then trying to evaluate anything will return nil and the following message:

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

If it's a shadow-cljs specific behavior it might be worth mentioning that you have to visit the http://localhost:8080/ first before eval-ing in the docs

@Risto-Stevcev Thanks!
I'll update documents soon.
Here is a document for dev branch.

[liquidz]

I've cut a new release, and documents are updated.
