New version of AssetPackager

Thanks to Dan Kubb for alerting me to a new version of JSMin, the library used by AssetPackager to compress javascript.

With the release of the latest jQuery 1.1.1, it triggered a bug in how jsmin was treating characters within a regexp.

AssetPackager now has the latest version.

Also, for those using Prototype, the v1.5 release that comes with Rails 1.2.1 has a missing semi-colon on line 846. This of course breaks when compressed. To fix it, this line should have a semi-colon at the end. This:

if (params && /Konqueror|Safari|KHTML/.test(navigator.userAgent)) params += '&_='

Should be:

if (params && /Konqueror|Safari|KHTML/.test(navigator.userAgent)) params += '&_=';

Update: Michael Schuerig has posted this to the rails trac so hopefully this will be fixed soon. In the meantime, it’s pretty simple to make the change yourself.

Hash – to_query

Look what just appeared in Rails trunk – Hash#to_query – turn a hash of values into a form-encoded query string. I’ve wanted this on occasion in the past. Check it out:

Simple Conversion

{:a => 10}.to_query

Becomes this:

a=10

Nested Conversion

{:person => {:name => 'Nicholas', :login => 'seckar'}}.to_query

Becomes this:

person[name]=Nicholas&person[login]=seckar

Multiple Nested

{:person => {:id => 10}, :account => {:person => {:id => 20}}}.to_query

Becomes this:

account[person][id]=20&person[id]=10

Array Values

{:person => {:id => [10, 20]}}.to_query

Becomes this:

person[id][]=10&person[id][]=20

You can do the same thing in Prototype:

$H({ action: 'ship', order_id: 123, fees: ['f1', 'f2'], 'label': 'a demo' }).toQueryString();

Becomes this:

'action=ship&order_id=123&fees=f1&fees=f2&label=a%20demo'

It doesn’t look like Prototype handles the nested conversions yet though.
