5894 :: Extended routes that return json doesn't compile

• jjude (orginal) [2020-02-06T17:39:44+01:00] view original

  If I have all code in a single file:

  import jester, json
  
  routes:
    get "/":
      var jsonResp = $(%*{"id": 2})
      resp Http200, jsonResp
  Run

  This works well without any problem.

  Now if I split this into two files:

  main.nim

  import jester
  import api
  
  routes:
    extend apiv1, "/api/v1"
  Run

  api.nim (in the same folder)

  import jester, json
  
  router apiv1:
    get "/":
      var jsonResp = %*{"id": 2}
      echo jsonResp
      resp Http200, "hello"
  Run

  Then I get these errors:

  
  jester.nim(1277, 9) Hint: Asynchronous route: apiv1. [User]
  jester.nim(797, 9) Hint: 'settings' is declared but not used [XDeclaredButNotUsed]
  jester.nim(1307, 26) Hint: 'apiv1ErrorHandler' is declared but not used [XDeclaredButNotUsed]
  jester.nim(1280, 7) Hint: 'apiv1' is declared but not used [XDeclaredButNotUsed]
  jester.nim(1277, 9) Hint: Asynchronous route: match. [User]
  jester.nim(1283, 35) template/generic instantiation of `async` from here
  /server/src/api.nim(5, 20) Error: undeclared identifier: '%*'
  Run

  I think it is a problem with creating json nodes. Can't understand how to resolve this.

  Thanks for your help.

  Add import json everywhere and try again, the compiler will tell you if some import is not needed and then remove it.

  Imports are a constant problem when dealing with macros, the only solution seems to be to somehow use include

  export json
  Run

  in the api.nim also works
