ysyx*:0001:Scala & Chisel

Scala

• val for immutable, var for mutable
• need {} to define a block of code
• if condition need ()
  if block return value, it will be the last line of the selected block
• function definition:
  def funcName(param1: Type1, param2: Type2): ReturnType = { ... }
def could in def (local function)
  return value is the last line of the block
• List is scheme like (head, tail)
• for loop: for (i <- 1 to 10) { ... }
to [left, right] (inclusive)
  until [left, right) (exclusive)
  by step len
  for (value <- randomList) { ... } iterate over iterable
• import A.B._ or import A.B.{C, D}
• OOP: like python, the class block is the constructor
  s"string $var, ${var1 + var2}" string interpolation
