  • C3

    C3 is a programming language project, inspired by C, Elixir and Common Lisp. It could be described as C with Elixir macros, pattern matching, and a semantic object system. The idea is to plug macros and pattern matching into C89 and use them to implement the graph database.

    The garbage collector is optional, like in C.

    defmodule C3 do
  
  def compile (c3, opts) when is_string(c3) do
    c3
    |> C3.parse(opts)
    |> C3.compile()
  end

  def eval (c3, env, opts) when is_string(c3) do
    c3
    |> C3.parse(opts)
    |> C3.eval(env)
  end

  defguard is_c3 (x) do
    is_tuple(x)
  end

  def compile (c3, opts) when is_c3(c3) do
    c3
    |> C3.to_assembly(opts)
    |> Assembly.to_elf(opts)
  end

  def eval (c3, env) when is_c3(c3) do
    [...]
  end
end

    Structure

    libc3

    C3 is implemented using libc3 a small C89 library implementing the core of the language.

    The library includes a parser and an interpreter for C3 code in C structures.

    Parser

    The parser is recursive descent for now.

    AST

    The AST is represented as C3 data structures and can be meta-programmed in C.

    Interpreter

    Under development.

    ic3

    Interactive shell. Under development.

    c3s

    Script interpreter. Under development.
