Publish a single file with emacs org-mode

I often write small articles on some experience I make, and since I want to move towards using static pages more often, I tried using emacs org-mode publishing for that. Strangely the simple usecase of publishing a single file seems quite a bit more complex than needed, so I document the steps here.

This is my first use of org-publish, so I likely do not use it perfectly. But as it stands, it works. You can find the org-publish version of this article at draketo.de/proj/orgmode-single-file.

1 Why static pages?

I recently lost a dynamic page to hackers. I could not recover the content from all the spam which flooded it. It was called good news and I had wanted to gather positive news which encourage getting active - but I never really found the time to get it running. See what is left of it: http://gute-neuigkeiten.de

Any dynamic page carries a big maintenance cost, because I have to update all the time to keep it safe from spammers who want to abuse it for commercial spam - in the least horrible case. I can choose a managed solution, but that makes me dependant on the hoster providing what I need. Or I can take the sledgehammer and just use a static site: It never does any writes to the webserver, so there is nothing to hack.

As you can see, that’s what I’m doing nowadays.

2 Why Emacs Org-Mode?

Because after having used MacOS for almost a decade and then various visual-oriented programs for another five years, Emacs is nowadays the program which is most convenient to me. It achieves a level of integration and usability which is still science-fiction in other systems - at least when you’re mostly working with text.

And Org-mode is to Emacs as Emacs is to the Operating System: It begins as a simple todo-list and accompanies you all the way towards programming, reproducible research - and publishing websites.

3 Current Solution

Currently I first publish the single file to FTP and then rename it to index.html. This translates to the following publish settings:

(setq private-publish-ftp-proj (concat "/ftp:" USER "@" HOST ":arnebab/proj/"))

(setq org-publish-project-alist
      '(("orgmode-single-file"
         :base-directory "~/.emacs.d/private/journal"
         :publishing-directory (concat private-publish-ftp-proj "orgmode-single-file/")
         :base-extension "org"
         :publishing-function org-html-publish-to-html
         :completion-function (lambda () (rename-file 
                                          (concat private-publish-ftp-proj 
                                                  "orgmode-single-file/2013-11-25-Mo-publish-single-file-org-mode.html") 
                                          (concat private-publish-ftp-proj 
                                                  "orgmode-single-file/index.html") t))
         :section-numbers nil
         :with-toc t
         :html-preamble t
         :exclude ".*"
         :include ["2013-11-25-Mo-publish-single-file-org-mode.org"])))

Now I can use C-c C-e P x orgmode-single-file to publish this file to the webserver whenever I change it.

Note the lambda: I just copy the published to index.html, because I did not find out, how to rename the file by just setting an option. :index-filename did not work. But likely I missed something which would make this much nicer.

Note that if I had wanted to publish a folder full of files, this would have been much easier: There actually is an option to create an automatic index-file and sitemap.

For more details, read the org-mode publishing guide.

4 Conclusion

This is not as simple as I would like it to be. Maybe (or rather: likely) there is a simpler way. But I can now publish arbitrary org-mode files to my webserver without much effort (and without having to switch context so some other program). And that’s something I’ve been missing for a long time, so I’m very happy to finally have it.

And it was less pain that I feared, though publishing this via my drupal-site, too, obviously shows that I’m still far from moving to static pages for everything. For work-in-progress, this is great, though - for example for my Basics for Guile Scheme.

Use Node:

⚙ Babcom is trying to load the comments ⚙

This textbox will disappear when the comments have been loaded.

If the box below shows an error-page, you need to install Freenet with the Sone-Plugin or set the node-path to your freenet node and click the Reload Comments button (or return).

If you see something like Invalid key: java.net.MalformedURLException: There is no @ in that URI! (Sone/search.html), you need to setup Sone and the Web of Trust

If you had Javascript enabled, you would see comments for this page instead of the Sone page of the sites author.

Note: To make a comment which isn’t a reply visible to others here, include a link to this site somewhere in the text of your comment. It will then show up here. To ensure that I get notified of your comment, also include my Sone-ID.
