Shorthand alternative for respond_to

If you have a simple respond_to block in your controller that looks like this:

respond_to do |format|
  format.html
  format.xml
end

You can use this alternate syntax and save a few keystrokes..

respond_to(:html, :xml)

Ok so it may not give you a huge performance boost, but if you’re obsessed with reducing the size of your code, this is a nice way to make a saving!

Comment on Shorthand alternative for respond_to by Anton Jenkins

Nice tip! It may only be a few keystrokes, but every little bit helps and it's certainly not obscuring the intent of the code. What I don't like is when these little tricks take something which did read perfectly and turn it into something which is considerably shorter, but you've no idea what it's doing at a glance!

You can use Markdown in your comment as well as plain HTML. You can use <filter:jscode lang="ruby"> and </filter:jscode> tags to surround code blocks (supported languages are css, html, javascript and ruby). Your email address will not be published.

If your comment doesn’t appear immediately after posting it could have been marked as spam. Don’t worry: we regularly check for and approve incorrectly filtered comments so you shouldn’t have to wait too long for it to be shown.
