Square Language

This is a very minimal toy language built for learning purposes, the objective was to create a language and write Fibonacci in it, the language uses flex and bison to parse a simple AST that is executed by a C program I have some plans on transforming the AST into x86 instructions in the future the language have the following syntax.

Fibonacci in square

[>:fib n:
  [:if n < 3:
    return n - 1
  ]
  return [:fib n - 1] + [:fib n - 2]
]
[:fib 10]

Function declaration

[>:fib n:
  return n
]

Function calls

[:fib 10]

If statements

[:if n < 3:
  return n - 1
]

Basic arithmetics

1 + 2
x + y
y + 3
