    One line publishing

    why, 1-liners are crucial:

    I’m not suggesting that one-liners are the heart of all programming. But they can be the hook to get someone exploring. A single line of code simply shows that a language can be focused. And it lets a beginner get comfortable with the basic atoms.

    Publishing a blog post using SPP:

    curl -d title=HAI!&content=I+has+SPP&status=published https://labotes.org/publish [authentication]

    I submit as evidence that any request you cannot illustrate with a one-liner curl is indistinguishable from SOAP.

      Great point. Love the illustration, and that’s why I love REST-like (though GET/POST only) web services like Amazons.

      (how come you can’t beat the comment spam with Spam Karma or Akismet?)

      I use Akismet and it works wonders, except for the occasional hiccups. I guess I should take the plunge and de-moderate comments.

      You can write Atompub POSTs with a curl one-liner too. The line will just be a little longer. :-)

      Of course, that ignores hypermedia, and hence it’s impossible to decide whether the protocol demonstrated by a curl one-liner uses HTTP merely as a transport or in fact as the application protocol.

      I’d like to see that one-liner, though I’ll need a 40″ monitor and very narrow font to fit it all in one line :-)

      Actually with an 8px font on my 1400×1050 screen (regular 20″ TFT), it fits on a single line:

      curl -H 'Content-Type: application/atom+xml;type=entry' \
      --data-binary 'HAI!I has APPurn:null:"'$(date -Is)"'' \
      https://labotes.org/publish

      So nyah. Now use some real text with actual HTML tags in the content instead of just 12 characters of filler total and we’ll see how much contrast remains.

      Or how about uploading a picture:

      curl -H 'Content-Type: image/jpeg' --data-binary @inurprotocolz.jpg https://labotes.org/publish

      That’s actually shorter! Errm, oops, I forgot SPP can’t even do that. :-)

      Err, d’oh, I forgot to escape the angle brackets:

      curl -H 'Content-Type: application/atom+xml;type=entry' \
      --data-binary '<entry xmlns="http://www.w3.org/2005/Atom"><title>HAI!</title><content>I has APP</content><id>urn:null:</id><updated>"'$(date -Is)"'</updated></entry>' \

      Generally speaking, Web browsers wouldn’t have a problem uploading images to SPP using multipart/form-data. To get the same effect using curl:

      curl -F ‘content=@inurprotocolz.jpg;type=image/jpg’

      I much prefer image/png, but otherwise looks fine to me :-)
