7869 :: Getting varargs parameter from JS

• drkameleon (orginal) [2021-04-27T14:01:09+02:00] view original

  So, I have a proc in Nim, exposed to JS, like:

  proc main*(txt: cstring, params: varargs[JsObject] = []): JsObject {.exportc:"A$".}=
        for param in params:
              discard # do something with param
  Run

  However, it doesn't seem to be working ok. Basically, when the function (A$) gets called with just one parameter (txt), there is an error.

  How do I properly handle that?

  @drkameleon, I believe this is a bug. Please report it on the Nim issue tracker. If you call the function from Nim, you get the expected result, but when calling from js, there is an error in the browser console and params is not defined.
