lutcc

Lutin compiler. Complete description of the language in grammar.md.

Example lutin code

var x;
const n = 10, n2 = 100;

ecrire n + n2;
x := n + n2;
ecrire x + 2;
lire x;
ecrire x;

This program declares one variable and two constants, writes 110 to the standard output, affects a value to x which is then written, and finally, it writes the user input on the standard output.

Notes:

• Declarations (var and const) must be done before any instruction.
• ecrire means write to standard output, and lire means read from standard input.
• The language only supports integers
• If a litteral is on the right-hand side of an assignment, it can't be negative
• Constants must be initialized with a positive integer litteral
• Variables may not be initialized
