Awesome

Crimson is an "object notation" language, similar in respect to JSON. It intends to build an object notation for a typed language. Heavily inspired by Ron 'Rust object notation'.

Maintenance/usage: This isn't a finished project, or a project under active sustained development. It's something I work on from time to time between other projects...

Expect it to change incompatibly from it's current state.

• Goals:

  • Typed(?)
  • Type inference
  • Differentiate between Ordered and unordered collections.
  • Natural support for graph-like data.
  • Allow type definitions and pure constructors.
  • Allow enum constants and user defined structs.
  • Ranges as first class types.
  • Constants
  • Efficient support for collections of data with fixed size children.

• Non-Goals:

  • Easily edited (If we run out of brackets, we may use ones from unicode)

• Array: [a, b, c],
• Set: {a, b, c},
• Map: {A=a, B=b}.
• Range: start..end,
• Char: 'c',
• String: "foo",
• N-tuple (a, b, c)

Types go first and are enclosed in <>

Types: <Array(<String({Len=3})>, {Len=2})>{"wor", "hel"}

Crimson allows user declared types, in a type header, subsequent values can then refer to these by name:

struct Foo {
  foo: String
}

#[repr(u8)]
enum Bar {
  A = 0,
  B,
  C,
}
