var parser = matcher({
_ : "^",
user : "\\w+", // can also pass a JS RegExp here
_2 : "@",
host : "[^@]+",
_3 : "
quot;
});
var parts = parser("benji@somewhere.com");
console.log(parts.user); // benji
console.log(parts.host); // somewhere.com
Example primitive URL parser:
var m = matcher({
protocol : "http|https",
_1 : "://", // can also pass a RegExp here
host : "[^/]+",
_2 : "/",
path : ".+",
_3 : "quot;
})("http://www.google.com/search?foo=bar");
m.protocol; // http
m.host; // www.google.com
m.path; // search?foo=bar
Note: In "real code" use the built-in parsing capabilities of browsers/node to parse real URLs.
Motivation
Matching nested RegExps is hard to read. The goal of this package is to allow users to match common patterns without having to parse the capturing groups of complex regular expressions and put those in object fields. This "shims" the lack of named capturing groups in JavaScript.
