8221 :: Can't create sequence with newSeq

• Gadersd (orginal) [2021-07-11T21:34:09+02:00] view original

  I have a Matrix object defined as follows:

  type
     Matrix* = object
        numRows* : int
        numCol* : int
        data : seq[float]
  Run

  When I call newSeq[Matrix](3) I get the error "Error: expression 'Matrix' has no type (or is ambiguous)." What is the reason for this?

  All fine:

  type
    Matrix* = object
      numRows* : int
      numCol* : int
      data : seq[float]
  
  var m = newSeq[Matrix](3)
  Run

  Do you have Matrix declared in Matrix.nim if so you're refering to the module when you do Matrix so either rename the file to matricies or do Matrix.Matrix to access the type, the former is more idiomatic.

  Renaming the file to matrix.nim solved my problem. Thanks!
