zeal-lang

Zeal Programming Language.

Goals

• Syntax is lua-ish in ml style

• Native embedable Rust bindings.

• Unobstructive Static Typing (somewhat similar to Go)

• JIT or AOT compilation

• Module System

• documentation generation and typespecs similar to RustDoc or Elixir's @doc

• Runtime AST and compile time macros

• package manager & cli tool for Zeal (simliar to npm/cargo, name tentative)

• Structs, no classes

• Traits: Something between Rust and Go

• Pattern matching / Destructuring

• Optional Types (nil exists but I may remove it in favor of optional types, nonetheless Optional types will be a feature no matter what)

• Pipe operator

• Pass instance to method function automatically (instance.method() and method(instance) are both legal syntax and express the same method/function call)

Open Considerations

• No Nil and Optional Types? or both?
• Mutiple Dispatch or Static/Dyn Dispatch

Declarations

• var :: binding can be reassigned, eg: var x = 1; x = 3; Does not allow rebinding (shadowing).
• let :: similar to Rust's let, allows rebinding (shadowing), but not reassignment
• const :: Does not allow rebinding, or reassignment, unique identifier in current scope.

Compile Targets

• ECMAScrit/WebAssembly
• LLVM:
• Mu Micro Virtual Machine
• ZealVM

Tentative syntax

` mod math

fn add(a i32, b i32): i32 a + b end

fn sub(a, b) = a - b

struct Point x u32 y u32 end

fn mutate_point(p mut Point) p.x = p.x * p.x end

`
