6947 :: Aliases with templates for tables not working in v1.4

• jasonfi (orginal) [2020-10-18T09:53:56+02:00] view original

  Here is an example of code that worked in v1.2.6:

  template my_alias: untyped = my_table[my_id]
  Run

  I now get an error:

  key not found: 4387866928

  This key value is not the value of my_id. Is there a new syntax for creating aliases with templates in v1.4?

  Seems to work, what code are you using

  The problem seems to occur when the template declaration is in a for loop: https://play.nim-lang.org/#ix=2B80

  you can declare the template outside the for loop, or:

  for my_id in my_id_seq:
    
    template my_alias: untyped {.dirty.} = my_table[my_id]
    echo my_alias
  Run
