A template literal tag that lets you write verbose regex syntax

demo.js

var r = require("./verboseRegex.js");

var regex = r`
^        # from the start of the string
\s*      # with any number of spaces
\(\s+    # find the first paren, followed by whitespace
([^)]+)  # capture anything that's not a closing paren
\s*\)     # followed by whitespace and a closing paren
`;

console.log(r); // logs out /^\s*\(\s+([^)]+)\s*\)/;

verboseRegex.js

var regex = function(parts) {
  var stripped = parts.raw.join("").replace(/\s|\n|\s*#.*$/gm, "");
  return new RegExp(stripped);
};

module.exports = regex;
