posting to wordpress via ruby and atompub

The ruby script here uploads posts to WordPress blogs via AtomPub.

Once you’ve set your blog coordinates in the script (around line 20), you can post like that :

echo "I love Ruby" | post.rb -t "title" -c "thoughts,ruby"

The script will publish your post and then ouptput the WordPress server reply.

raise "please specify a title for the post with the -t option" \

#
# gather content

    line = STDIN.gets
    break unless line
    content += line

#
# create entry

entry = Atom::Entry.new
entry.title = title
#entry.updated = Time.now.httpdate
entry.updated!

author = Atom::Author.new
author.name = authorname
author.uri = bloguri
entry.authors << author

tags.each do |t|
    c = Atom::Category.new
    c["scheme"] = bloguri
    c["term"] = t.strip
    entry.categories << c
end

entry.content = content
entry.content["type"] = type if type

#puts entry.to_s

h = Atom::HTTP.new
h.user = username
h.pass = password
h.always_auth = :basic

c = Atom::Collection.new(base + "/posts", h)
res = c.post! entry

puts res.read_body

Next step for me, integration of the technique into ruote.

Updated 2007/11/11 : following the suggestions of Brendan Taylor, the author of atom-tools, I simplified the scripts, now relying on atom-tools for posting the entry.

Enjoy.
