C++ Signatures

C++ function signature parsers.

Motivation

C++ is really hard to parse. However, we can still use regular expressions to tokenise some common expressions:

import { Signature } from "cpp-signatures";

const signature = new Signature("F map(std::function<A(A)> mapper, F vec)");

console.log(signature);

{
  "name": "map",
  "inputs": [
    {
      "name": "mapper",
      "typename": "std::function<A(A)>"
    },
    {
      "name": "vec",
      "typename": "F"
    }
  ],
  "output": {
    "name": null,
    "typename": "F"
  }
}

We can also format the signatures to Haskell style type signatures:

new Signature("int increment(const int &x)").format();

"const int & -> int"

This includes lambda expressions:

new Signature("FA map(const std::function<A(A)> &mapper, FA vec)").format();

"(A -> A) -> FA -> FA"

Note we have omitted the const and & from const (A -> A) & for brevity.
