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.

    unless title

# gather content

content = ""
loop do
    line = STDIN.gets
    break unless line
    content += line

# create entry

entry =
entry.title = title
#entry.updated =

author = = authorname
author.uri = bloguri
entry.authors << author

tags.each do |t|
    c =
    c["scheme"] = bloguri
    c["term"] = t.strip
    entry.categories << c

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

#puts entry.to_s

h =
h.user = username
h.pass = password
h.always_auth = :basic

c = + "/posts", h)
res =! 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.

  1. […] Use ruby and atompub to post to WordPress […]

  2. I can’t get this to work…
    I have WordPress hosted on my site (I don’t know if this makes a difference).
    At first I got an ECONNREFUSED error.
    I changes the https in the base string to http, and I got “No input file specified”.
    I also have a (related?) problem with my pipe:
    I get “The process tried to write to a nonexistent pipe”…

    Please help?

  3. Hi Tal,

    please send me a more detailed error report at

    Include details about which version of Ruby you utilise and perhaps make sure your WordPress has its AtomPub API turned on (I don’t know anything about WP administration as I gladly uses only).

  4. […] posting to wordpress via ruby and atompub (tags: blog wordpress atom ruby web programming) […]

  5. Strange thing is, I had build an auto email-to-wordpress system that pulled from a POP3 box, did some processing of attachments and the like and uploaded entries to WordPress… I last used in the first part of January 2008. I wanted to reactivate it, but now get weird errors when it tries to post, something about not having the right credentials even though it is logging in, getting the collections, and using that information to post the entries. It may be something the WP admin changed, or some WP change itself, but I was wondering if anyone else had seen this.

  8. Steve,

    > Atom::Unauthorized You must provide a username and password

    seems like you’re not providing a username and a password (or maybe they are outdated).

    The example I have blogged here used atom-tools 0.9.3.

    Best regards.

    update : I just tested this script with atom-tools 2.0.1 and it works fine.

  9. Strange. Well, I know I hadn’t changed anything, so it must be something the WP admin did or something in the WP updates. I just wanted to verify it wasn’t a general problem, at least now I know it’s all mine. ;)

  15. Hi John,

    Ok Thanks.

  17. Wow, thats a nice piece of code, It´s three years old and its still working, Thank you for coding and sharing it ;)

  18. Hi there, I am getting the same error. I changed the https in the base string to http, and I got “No input file specified”. Was there a solution to this previously??

    • Sorry, what error are you referring to ?

      This script is four years old, it probably needs some rework to adapt to the newer versions of atom-tools & co.
