#+title: pebble-lang

* Usage

Run ~zig build run -- compile filename~ to execute the interpreter pipeline on the contents of =filename=

or

run ~zig build run -- interactive~ to start the interactive REPL shell.

* Example

Computing the first =N= fibonacci numbers:

#+begin_src

declare N = 10

declare n1 = 1, n2 = 1, i = 1

while i <= N  {

      i = i + 1

      print n1

      declare TMP = n1

      n1 = n1 + n2

      n2 = TMP

}

#+end_src

which results in output

#+begin_example
