Since lately i've been working a lot with Ruby (Android and Java as well, but that's a different story), i figured i posted a couple of interesting gems that will make your life easier, especially but not only for rails.
Slim is a templating engine (like ERB or HAML) which pursues simplicity. It helps you write an insane amount less HTML and Rails code. You will not believe your eyes. An example:
<p>This example shows you how a basic Slim file looks like.</p>
<%= yield %>
The same in Slim
h1 Markup examples
p This example shows you how a basic Slim file looks like.
Now tell me which one you prefer to write ;)
A fantastic tool to format dates based on human readable formats. Why use Date.today.strftime("%Y/%m/%d") when you can use Date.today.stamp("2012/12/13")? Sweet, right?
Bugsnag is web site exception grabbing on steroids. It basically monitors your website alerting you of any exceptions and providing the relevant information needed so you don't have to debug your production server.
Cool thing is, there are "bindings" for multiple languages and frameworks. You can find the one for Ruby/Rails here.
Honey badger has a really simple purpose: To make sure you know which server you are in (say, testing, dev, production) by displaying a small "badge" with the name of your choosing.
If you are like me you can easily think you are debugging something in testing when you are really looking at production. Ok, maybe that's just me, but the badge does look cool, right? :)
Now, i'm not one to call the name of the Lord in vain (i am!), but God is something i can no longer do without. It's a process monitoring framework written in ruby that keeps an eye on your server's, say nginx, apache or mysql and makes sure they are always up.
Further checks can be done, like for example restart the server when memory usage goes above X or CPU usage goes above Y. It is also capable of notifying you by email, jabber, twitter, you name it, when things happen. It's a true life saver :)
Hope you find these gems useful, as i did, and if you have some that i might find interesting, please do share via twitter :)
