About

can is a stack-based programming language written in rust. It is currently at the earliest stages of its development and basically copies the syntax of Tsoding's Porth.

Features

• arithmetic operations
• bitwise logic operations
• dump (print number from the top of the stack)
• if-else statements
• while loops
• memory addressing
• syscalls
• C-style comments (//)
• Turing complete

Basic program

While loop that prints numbers 1 to 10

10 0 while 2dup > do 
    1 +
    dup dump
end

Fibonacci sequence

// prints first 10 numbers of Fibonacci sequence

mem 1 + 0 . // first
mem 2 + 1 . // second
mem 3 + 0 . // temp

// breaks after number 255 because we're using bytes :)
10 0 while 2dup > do
    1 +
    mem 3 + mem 1 + , mem 2 + , + . // sum two numbers and put result in temp value
    mem 1 + mem 2 + , . // put second number in place of first
    mem 2 + mem 3 + , . // put temp value in place of second
    mem 3 + , dump // print
end
