PizzaLang

This is about a new programming language called PizzaLang. Idea here is to explore implementing a new programming language.

Notes

This code has been crafted following the examples from https://llvm.org/docs/tutorial/MyFirstLanguageFrontend.
It does not use any engineering best practices and it certainly does not reflect my personal style of coding.
You can find many pizza program examples in the examples folder.

cd build
cmake ..
make

bake should be available at build/bin folder.

Keyword	Description	Example
base	Similar to `function` in other programming languages it declares a function	`base inc(x) x + 1;`
topping/in	Similar to `var` it delcares a variable	`topping x = 1 in print(x);`
sauce	Similar to `extern` it allows access to members declared in libs	`sauce print(x);`
if/then/else	Control flow, jumps depending on condition	`if x < 3 then print(0) else print(x);`
for/in	Control flow loops depending on condition	`for i=0, i<5 in print(i);`
binary	Allows creation of custom binary operators	`base binary\| 5 (L R) if L then 1 else if R then 1 else 0;`
unary	Allows creation of custom unary operators	`base unary!(v) if v then 0 else 1;`

Operator	Description	Example
`=`	Sets a topping (variable) or an argument's value	`base test(x) x = 1;` or `topping x = 1;`
`<`	Compare numbers return either 0, 1	`10 < 5;`
`+`	Adds numbers	`1 + 2;`
`-`	Subtracts numbers	`1 - 2;`
`*`	Multiplys numbers	`1 * 2;`
`/`	Divides numbers	`1 / 2;`
`()`	Lists args in bases (functions) and can change order of precedence	`base test(x) x = 1;` or `(1 + 2) * 3`
`{}`	Scopes, allows you to add groups of statements	`{ topping x = 1; x = x + 1; print(x); }`

Sauce	Description	Example
`print`	Prints to stdout argument's value	`print(10);`
`printchar`	Print the char to stdout	`printchar(10); # prints \n`
