Simple script to get all Redis commands in a format that mranney/node_redis can use.

node_redis_commands.js

var http = require('http');
var fs = require('fs');
var redisio = http.createClient(80, 'redis.io');

function getCommands() {
	var commandrequest = redisio.request('GET', '/commands.json', {'Host': 'redis.io'});
	commandrequest.end();
	var commandsfile = fs.createWriteStream('commands.json');

	commandrequest.on('response', function (response) {
	  response.setEncoding('utf8');
	  response.on('data', function (chunk) {
	    commandsfile.write(chunk);
	  });
	  response.on('end', function() {
		fs.readFile('commands.json', 'utf8', function (err, res) {
			process(JSON.parse(res));
		});
	  });
	});
}

function process(commands) {
	var results = {};
	for (var command in commands) {
		if (!results[commands[command].group]) { results[commands[command].group] = []; }

		// Process 'em.
		var processed = command.toLowerCase();
		if (processed.indexOf(' ') !== -1) {
			continue;
			// Camel Case!
			var temp = processed.split(' ');
			for (var i = 1; i < temp.length; i++) {
				temp[i] = temp[i].charAt(0).toUpperCase() + temp[i].slice(1);
			}
			processed = temp.join('');
		}
		results[commands[command].group].push(processed);
	}

	// Output pretty
	var output = "[ \r\n";
	for (var group in results) {
		output += "    \/\/ " + group + "\r\n";
		output += "    \"" + results[group].join('", "') + "\",\r\n"
	}
	output = output.slice(0, -3);
	output += "\r\n]";
	console.log(output);
}
