Redcarpet 3.0.0 now available!

09 Jul 2013

Robin, Vicent ,and I are happy to announce the release of Redcarpet 3.0.0! We’ve got the usual line up of goodies to talk about, so let’s get to the good stuff.

Backwards Compatibility

We’ve removed support for Ruby 1.8.x in this release. If you still need Ruby 1.8.x support, then you’ll need to stick with Redcarpet 2.3.0.

We’ve also removed the sundown submodule that was included in the Redcarpet codebase. Sundown has been deprecated for some time and all the code has been included in the redcarpet repository for awhile as well. So long Sundown and thanks for all the fish.

New features

Highlight support

We’ve got a new option you can pass to the Redcarpet::Markdown object: :highlight. This feature will let you use wrap a bit of text in a pair of equals signs and Redcarpet will generate markup that will cause it to be highlighted. If you want to use this option, you can use the following Ruby code:

markdown = Redcarpet::Markdown.new(Redcarpet::Render::HTML, :highlight => true)

to render the following markdown

This is ==highlighted== text, yo.

as

This is <mark>highlighted</mark> text, yo.

Thanks to Sam Soffes for contributing this. If you want to see it in action before you give it a try, check out Sam’s blog.

Bug fixes

We’ve fixed several issues in the Redcarpet codebase in this release. Here are some of the highlights:

  • Fixed an issue where mixing code spans and emphasis mangled the output (#135 and #190)
  • Fixed an issue where nested parenthesis in a link didn’t render correctly (#237)
  • Fixed an issue where FTP URIs were misidentified as email links when using autolinking (#170)
  • Fixed an issue where emphasis inside parenthesis was not parsed correctly (#256)
  • Fixed an issue where HTML comments were being needlessly escaped (#268)

Thanks to Robin Dupret for fixing all of these!

Wrapping this up

We’re really excited about Redcarpet 3.0.0 and hope you enjoy using it as much as we enjoyed making it. If you have any issues, please feel free to file an issue and we’ll take a look at it.

Thanks!
