Some bug fixes:
* An important bug fix in reconnection logic. Previously, reply callbacks would be invoked twice after a reconnect. * Changed error callback argument to be an actual Error object. New feature: * Add friendly syntax for HMSET using an object.

## Friendlier hash commands
|
||||
|
||||
Most Redis commands take a single String or an Array of Strings as arguments, and replies are sent back as a single String or an Array of Strings. When dealing with hash values, there are a couple of useful exceptions to this.
|
||||
|
||||
### client.hgetall(hash)
|
||||
|
||||
The reply from an HGETALL command will be converted into a JavaScript Object by `node_redis`. That way you can interact
|
||||
with the responses using JavaScript syntax.
|
||||
|
||||
Example:
|
||||
|
||||
client.hmset("hosts", "mjr", "1", "another", "23", "home", "1234");
|
||||
client.hgetall("hosts", function (err, obj) {
|
||||
console.dir(obj);
|
||||
});
|
||||
|
||||
Output:
|
||||
|
||||
{ mjr: '1', another: '23', home: '1234' }
|
||||
|
||||
### client.hmset(hash, obj, [callback])
|
||||
|
||||
Multiple values in a hash can be set by supplying an object:
|
||||
|
||||
client.HMSET(key2, {
|
||||
"0123456789": "abcdefghij",
|
||||
"some manner of key": "a type of value"
|
||||
});
|
||||
|
||||
The properties and values of this Object will be set as keys and values in the Redis hash.
|
||||
|
||||
### client.hmset(hash, key1, val1, ... keyn, valn, [callback])
|
||||
|
||||
Multiple values may also be set by supplying a list:
|
||||
|
||||
client.HMSET(key1, "0123456789", "abcdefghij", "some manner of key", "a type of value");
