explain-malli options documented here: https://github.com/paintparty/bling?tab=readme-ov-file#options-for-explain-malli

:callout-opts is what you would use to change the underlying callout label text (top header)

Options for the underlying callout documented here: https://github.com/paintparty/bling?tab=readme-ov-file#callout-blocks

Here’s a bunch of examples you can try on your side w/various options:

(require '[bling.explain :refer [explain-malli]])

(def Address
  [:map
   [:id string?]
   [:tags [:set keyword?]]
   [:address
    [:map
     [:street string?]
     [:city string?]
     [:zip int?]
     [:lonlat [:tuple double? double?]]]]])

(def v 
  {:id      "Lillan"
   :tags    #{:artesan "coffee" :garden}
   :address {:street "Ahlmanintie 29"
             :city   "Tempare"
             :zip    33100
             :lonlat [61.4858322, 87.34]}})

(explain-malli Address v {:display-schema? false :callout-opts {:label "Custom Label"}})

(explain-malli Address v {:display-schema? false :callout-opts {:label "Custom Label" :label-theme :minimal}})

(explain-malli Address v {:display-schema? false :callout-opts {:label "Custom Label" :theme :sideline-bold}})

(explain-malli Address v {:display-schema? false :callout-opts {:label "Custom Label" :theme :sideline-bold :label-theme :minimal}})

(explain-malli Address v {:display-schema? false :callout-opts {:label "Custom Label" :theme :gutter}})

(explain-malli Address v {:display-schema? false :callout-opts {:label "Custom Label" :theme :gutter :label-theme :minimal}})

(explain-malli Address v {:display-schema? false :callout-opts {:label "Custom Label" :theme :gutter :margin-left 3 :label-theme :minimal}})

Glad I found this thread. I need something similar, but I thought maybe just filtering out valid keys in maps would be sufficient. And for seqs, possibly just converting to a map of int (the idx) to error. But I'm assuming the problem is more complex than that.

@ambrosebs thanks for the referral! The new bling.explain/explain-malli function is now included the https://clojars.org/io.github.paintparty/bling. @joel380 Thanks for the ticket, I https://github.com/paintparty/bling/issues/38#issuecomment-2972605044. Let me know if you have any luck with the latest version. As far as compactness you can set :display-schema? to false and :spacing to :compact as https://github.com/paintparty/bling?tab=readme-ov-file#options-for-explain-malli

@joel380 yeah the :or handling is too verbose. I think other solutions have similar issues. I outlined some heuristics we could try implementing here https://clojurians.slack.com/archives/CLDK6MFMK/p1748559223421159?thread_ts=1748550434.774499&cid=CLDK6MFMK

@jcoyle Is there also a way to change “Malli Validation Error” (top header)?

So the value for us is often page(s) and the schema is at least a whole page (the whole registry), so while the info is there it’s definitely an overload with a bunch of irrelevant information. I’ll give bling a try, if it can highlight where the errors are that could be helpful, although it would be nice if it could make it concise as well.

It might be constructive to read the 3-4 threads gathering feedback about bling starting here https://clojurians.slack.com/archives/CLDK6MFMK/p1748550311357469

I think I had a couple of ideas for concision.

Pretty sure I found a bug with bling, which I’ll file a ticket for as it looks pretty promising, but maybe not quite there yet.

Was there a specific problem with humanized errors that made it too verbose?

I’m finding one problem

::test-specs [:or ::test-spec [:sequential ::test-spec]]}

I did still get an error like this… it’s indicating the position of the error.
