1147 :: Array declaration

• svampa (orginal) [2015-04-20T16:56:07+02:00] view original

  I know it is a little arrogant from me, a beginner, to raise objections. But here they are:

  This is an array of integers

  var a: array [0..10,int]

  Wouldn't if had been better something like this?

  var a: array [0..10] of int

  or

  var a: int[0..10]

  Or whatever that don't make item's type look like an index.

  I think it's a great language. Of course, there are things I would prefer other way, probably because I'm used to do other way, but that's my problem. Nevertheless, such declaration of arrays is really weird.

  What's the logic behind such syntax? I can't recall any language with such mess of index an base type.

  It is the generics syntax, and in arrays case, you are passing two type parameters to array, [index, type], which is consistent with other parts of the language, like seq[int] etc.

  It was a little weird for me at first. Now it's not. That's the nature of languages.

  It isn't a matter of logic so much but to me it does show consistency with other type declarations, like seq[int].

  EDIT: ...like @hakand said. ;-)

  var a: int[0..10]
  Run

  This would collide with slice syntax.

  var a: array [0..10] of int
  Run

  I prefer the comma. Less verbose. In fact, Nim is NOT a verbose language (Fortunately)
