This is a test project for nim book.

Code

Inline code snippet:

proc twice*(a: int): int =
  a * 2

This snippet is tested during documentation build:

proc twice*(a: int): int =
  a * 2

assert 10.twice == 20

The same but using .. code:: directive:

proc twice*(a: int): int =
  a * 2

proc twice*(a: int): int =
  a * 2

assert 10.twice == 20

Code included from a source file:

proc double*(x: int): int =
  x * 2

Selective inclusuion:

proc double*(x: int): int =
  x * 2

Doesn't have to be Nim code:

# This is Python
def double(x: int) -> int:
    return x * 2
