Usage

Usage of daleth is very simple:

var http = require('http');
var daleth = require('daleth')(
    [/^\/([a-z]+)\/?$/, function(request, response, args) {
        response.writeHead(200, {'Content-Type': 'text/html'});
        response.end('One argument: ' + args, 'utf8');
    }],
    [/^\/$/, function(request, response) {
        response.writeHead(200, {'Content-Type': 'text/html'});
        response.end('Pure root', 'utf8');
    }],
    [/^\/.*$/, function(request, response) { // Fallback
        response.writeHead(404, {'Content-Type': 'text/html'});
        response.end('Not found', 'utf8');
    }]
);

http.createServer(function (request, response) {
    daleth(request.url, function(handler, args) {
        handler(request, response, args);
    });
}).listen(8888);

daleth takes set of two-element arrays that contains regex and handler as arguments and returns "route" function. Regex is full JavaScript RegExp object that can include "search groups". Handler can be any object, not just a function.

"Route" function takes two arguments: path and callback. Callback also takes two arguments: routed handler and array of extracted matching search groups. If path includes "?" symbol, daleth trashes it and all trailing path.
