Hello, I want to build a general data-building ui, that takes a description of the datastructure as input (a malli schema, this time around). I couldn’t find much prior work in this regard. I have a half-baked prototype here: https://escherize.com/w/data-desk/
So far, that mostly works for int? string? boolean? :vector and :map and combinations of them.
So do you know of anything similar?

As for the implementation, I’m using a local atom and this multimethod: https://github.com/escherize/data-desk/blob/main/src/data_desk/views.cljs#L37

Ok. Thanls

I'd like to validate inside a function that the function is called with valid arguments.
Should I use :=> ? How exactly?

The readme doens't cover it
Yehonathan Sharvit 2021-06-17T12:48:54.172900Z
Here is what I am doing
Yehonathan Sharvit 2021-06-17T12:51:18.173100Z
(def =>plus [:=> [:cat int? int?] int?])
(defn plus [x y]
(when-not
(m/validate (second =>plus) [x y])
(throw (ex-info "invalid input" {})))
(+ x y))Yehonathan Sharvit 2021-06-17T12:51:28.173300Z
Is there a more idiomatic way?
ikitommi 2021-06-17T15:58:29.173700Z
there will be malli.instrument, while waiting, there is malli-indtrument - https://github.com/setzer22/malli-instrument
Yehonathan Sharvit 2021-06-20T07:12:35.181Z
Very cool! Any reason why it's not yet part of malli?
ikitommi 2021-06-20T07:16:04.181300Z
just time to merge & cleanup, the original issue is here: https://github.com/metosin/malli/issues/349
ikitommi 2021-06-20T07:18:54.181600Z
the function checker code shuould be reused between malli.generate and malli.instrument.
Yehonathan Sharvit 2021-06-21T07:43:01.182Z
Is someone already working on this consolidation?
ikitommi 2021-06-21T08:10:44.182200Z
please ask on the issue. on my summer backlog if no-one has time. need this too after the vacations.
Yehonathan Sharvit 2021-06-22T09:07:09.188200Z
ok. will do
ikitommi 2021-06-17T06:21:00.172200Z
README should cover that

Is there something I can do to make the results of mu/union more condensed?
(mu/union (mu/union nil? empty?) empty?)
=> [:or [:or nil? empty?] empty?]
