should we support plumatic style defn syntax (?) #28

Open jasonjckn opened 9 months ago

jasonjckn commented 9 months ago

Plumatic style function syntax :- can be found in a few libraries https://github.com/plumatic/schema#beyond-type-hints https://github.com/metosin/malli/blob/master/docs/function-schemas.md#function-schema-metadata https://github.com/gnl/ghostwheel

is there any desire to support this out-of-the-box? it might be challenging to add an user configuration mechanism for it , and there's not a lot of downside to understanding the optional syntax. This is a qualitatively distinct problem than supporting different function definition aliases 'defn', which is more amenable to user config.

:- appears both to denote function return type, as well as function parameter(s) type, the only place where support needs to be added is the function return type as far as I can tell.

it's a trivial change in clojure-ts--docstring-query , I'm using this rough code right now, but probably needs a :match expression the literal :-
