Hue

A lisp-like that can fit into your pocket

Example

(do int
    (puts "Hello there")
    (int i)
    (set i (add 1 2 3))
    (if i (do void
        (puts "If works")
    ))
    (return i) ; Return i
)

Note: the print function is not provided anywhere. It is assumed that the programmer added it after code generation.

Why

Choose Hue because:

• smol: Written less than 200 lines of C++-code
• sped: Generates C-code, the fastest in the universe
• strong, independent: By default code generated by Hue does not have any library dependencies. It can always call C-functions tho.
• familiar errors: As long as you follow basic syntax rules, Hue won't send you any errors. But your C-compiler will.

Syntax specifics

HUE statements are written like so: (<statement name> <statement arguments) Arguments can be more statements or simply primitives. Primitives are how you know them already: Numbers and strings:

• 0
• 42
• 36.3636
• "This is a string""

Lambdas

Similarly to lisp, HUE features lambdas. They are created with the do statement and can return a value using the return statement. These lambdas can be used anywhere including in if and while conditions and variable assignments. They can contain any instruction like a loop or even another lambda. Also they are the only feature HUE has that C doesn't.

Hacking HUE

If you want to add custom code generation to HUE simply do so by adding an overruling for a specific statement name. An overruling is a function that takes an expression of type Expr and returns a string of type std::string. If you fell the urge to generate code that shouldn't be directly in-place like functions or structs, simply add a string to functions
