whitespaces between two commas

[jangko]

this is the yaml script

scenes:
  - 
    duration: 9
    label:
      - {text: "...", position: {x:201, y:241} } 
      - {text: "...", position: {x:268, y:202} }
      - {text: "...", , position: {x:278, y:151} }
      - {text: "...", position: {x:348, y:111} }

this is the Nim code

import yaml/[parser, stream], streams

proc main() =
  var s = newFileStream("bug.yml")
  var p = newYamlParser()
  var ev = p.parse(s)
  
  try:
    for x in ev:
      echo x.kind
  except YamlStreamError as err:
    echo err.msg

main()

and this is the result:

...

[NimYAML] Please report this bug.

Is this really a bug?, I think I just put something wrong in the yaml script. Perhaps an alternate error message is better.

Btw, your yaml library is awesome

Well this is invalid YAML, but the parser does not properly handle it, therefore it is indeed a bug. It should not run into a failed assertion, but raise a proper parser error instead.
