7349 :: Why JSON % proc doesn't work for Enum?

• alexeypetrushin (orginal) [2021-01-07T11:54:23+01:00] view original

  The % proc specifying how Enum should be converted to JSON doesn't work, why, and how to make it work?

  playground

  import json, re
  
  type SomeEnum* = enum SomeName, OtherName
  
  func `%`*(s: SomeEnum): JsonNode = %(($s).replace(re"Name$", ""))
  
  echo %SomeName
  echo @[SomeName]
  Run

  Would produce

  
  "Some"
  @[SomeName]
  Run

  What do you mean it doesn't work?

  import json
  
  type SomeEnum* = enum SomeName, OtherName
  
  echo %SomeName
  Run

  Outputs "SomeName" as you would expect (well, you might expect 0 instead, but who knows).

  I defined custom JSON conversion for it func `%`*(s: SomeEnum): JsonNode it should use it.

  It does produce "Some". What's your problem?

  Yes, sorry, it works ok, my bad, please delete this question.

  P.S. I created simplified test case from some more complicated code and missed the % operator in this line echo %(@[SomeName]) didn't noticed it.
