I’ve published new gems in the Ruby Gem of the Week series that presents a new Ruby library every week on Thursday on Planet Ruby. The new gems presented include: Week #4 - kramdown gem - turn easy-to-read and easy-to-write; wiki-style plain text in markdown into hypertext Week #5 - feedparser gem - web feed parser and normalizers (for RSS 2.0, Atom, n friends). Happy Planet. Cheers. PS: Have your say! Guest posts or ideas and suggestions about gems more than welcome.
