Primi 0.2.4

• NEW: Range definition literals
  • Syntax:
    • left .. right
      • Creates an array having integer values from left to right using steps of (minus) 1.
    • left ..[step..] right
      • Creates an array having values from left to right using steps of step.
  • Only integer numbers and integer number variables can be used as boundaries for range/step definition. (Current implementation will coerce floats into integers.)
  • Example:

    r = 1 .. 5; // (array) [0: 1, 1: 2, 2: 3, 3: 4, 4: 5]
    r = 1 .. -2 // (array) [0: 1, 1: 0, 2: -1, 3: -2]
    a = 1; b = 5; r = a .. b // (array) [0: 1, 1: 2, 2: 3, 3: 4, 4: 5] 
    r = 1 ..2.. 5; // (array) [0: 1, 1: 3, 2: 5]
    r = 1 ..4.. 7; // (array) [0: 1, 1: 5]
    r = 1 ..4.. 3; // ERR: Invalid step '4' for range
    

    The syntax is still experimental and may be subject to change.
• NEW: Added two hashing functions to Primi Standard Library.
  • hash_md5(string|number)
    • Returns a string containing MD5 hash of string or number.
    • Example:

      "hello".hash_md5(); // (string) "5d41402abc4b2a76b9719d911017c592"

  • hash_sha256(string|number)
    • Returns a string containing SHA256 hash of string or number.
    • Example:

      "hello".hash_sha256(); // (string) "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824"
      

• Minor optimizations and fixes.
