Unhandled exception in example: hn.nim (Hacker News)

[Bahm]

hn.nim throws a KeyError exception when comments are disabled.

It works if you replace:

characters $call.json["descendants"].getInt() & " comments"

With:

try:
  characters $call.json["descendants"].getInt() & " comments"
except KeyError:
  characters "comments disabled"

The HN website just says "3 hours ago | hide" so it isn't a perfect match.

Here's the JSON for a HN post with comments disabled:

{
  "by": "thomaspaulmann",
  "id": 25217586,
  "score": 1,
  "time": 1606374063,
  "title": "Raycast (YC W20) Is Hiring Fullstack Software Engineers (EU, Remote)",
  "type": "job",
  "url": "https://raycast.com/jobs/software-engineer-fullstack"
}

Similar issue, solved with a similar fix:

try:
  let uri = parseUri(call.json["url"].getStr())
  characters "(" & uri.hostname & ")"
except KeyError:
  characters ""
