669 :: add()'ing to TTables with seq[T] values

• jester (orginal) [2014-12-12T17:48:01+01:00] view original

  I'm trying to make a hash table whose value is a sequence of some type and add to it. I'm probably missing something obvious.

  import tables
  
  var myTable = initTable[string, seq[string]]()
  
  myTable["keyA"] = newseq[string]()
  myTable["keyA"].add("a string")
  Run

  Compiling the above yields:

  main.nim(6, 7) Error: for a 'var' type a variable needs to be passed
  Run

  I changed the table's value-type to var seq[string] but I don't believe I understand the heart of the issue.

  What's the recommended way to make, and interact with, a table whose values are references to a sequence?

  It's a common gotcha (and about to be fixed). Use this instead:

  myTable.mget("keyA").add("a string")
  Run

  That's the ticket. Thank you very much.
