defstate macro is not recognized as var definition

[maxp]

The defstate macro from mount.core used to define special kind of vars.
But the editor shows an error popup with message that myvar is not defined.

(defstate myvar
  :start ...

As workaround for this problem declare could be used.

(declare myvar)

(defstate myvar
  ...

You are running into a limitation of the Joker linter. It doesn't do a full scan of all files and does not recognize defstate (in your case) as a macro. But all is not lost! To get rid of the error messages, add defstate to Joker's list of known macros. Create a .joker file somewhere in the path from the root of your project to where you are using the macro (I prefer to have it in the project root), and add:

{:known-macros [some-ns/defstate]}

Replace some-ns with whatever namespace you are requiring the macro from. Read more about Joker's linter mode here: https://github.com/candid82/joker#linter-mode

Please let me know if this solves your issue, and close the issue if so.
