7538 :: Question about using "include"

• kcvinu (orginal) [2021-02-20T13:52:16+01:00] view original

  Hi all, Lets assume that i have a 3 nim source files like this.

  #file1.nim
  var v1 : int = 1500
  #----------------------file1 ends here-----------
  
  #file2.nim
  var v2 : int = 2500
  #----------------------file2 ends here-----------
  
  #file3.nim
  include file1
  include file2
  
  var v3 : int = 3500
  #----------------------file3 ends here-----------
  Run

  I can use v1 & v2 in file3. It's okay. I know that nim is considering file1, file2 & file3 as single file in this case. But how do i use v3 in file1 or file2 ?

  You'd need to declare v3 before you include file1 and file2, like so:

  var v3 = 3500
  
  include file1
  include file2
  Run

  It's not strange, include will literally copy-paste the contents of the file, and in Nim, you can only use variables after they're declared.

  Yes. Its like write all your code in a single file and split it into multiple files. Well, i was searching for an option to get rid of circular module dependency problem.
