* Introduction
While the Emacs community have a plethora of options for generating a static website from org-formatted files, I keep my pretty simple, and use the standard =org-publish= feature.

While the following packages come with Emacs, they aren't necessarily loaded:

#+begin_src emacs-lisp :results silent
  (require 'ox-rss)
  (require 'ox-publish)
#+end_src

Variable settings:

#+begin_src emacs-lisp
  (setq org-export-with-broken-links t
        org-mode-websrc-directory "~/website"
        org-mode-publishing-directory (concat (getenv "HOME") "/website-pub/"))
#+end_src
* The Projects
I separate my /website/ into distinct projects separately built:

  - =blog-content= :: The bulk of rendering my =website= org files into HTML
  - =blog-static= :: All of the assets, like images are easily copied in place
  - =blog-rss= :: Regenerate the feeder files
  - =org-notes= :: Optionally render a non-web site collection of notes.

        `(("all"
           :components ("blog-content" "blog-static" "org-notes" "blog-rss"))

* Including Sections
In the project definitions, I reference a =pre-= and =postamble= that allow me to inject some standard HTML file headers and footers:

#+begin_src emacs-lisp
(defun org-mode-blog-preamble (options)
  "The function that creates the preamble top section for the blog.
    OPTIONS contains the property list from the org-mode export."
  (message "Preamble options: %s" (princ options))
  (let ((base-directory (plist-get options :base-directory)))
    (org-babel-with-temp-filebuffer (expand-file-name "top-bar.html" base-directory) (buffer-string))))

(defun org-mode-blog-postamble (options)
  "The function that creates the postamble, or bottom section for the blog.
  OPTIONS contains the property list from the org-mode export."
  (let ((base-directory (plist-get options :base-directory)))
    (org-babel-with-temp-filebuffer (expand-file-name "bottom.html" base-directory) (buffer-string))))
#+end_src

Another helper function for the content of website is to make sure to update =index.org=, so that the RSS gets generated.
#+begin_src emacs-lisp
(defun org-mode-blog-prepare (&optional options)
  "`index.org' should always be exported so touch the file before publishing."
  (let* ((base-directory (plist-get options :base-directory))
         (buffer (find-file-noselect (expand-file-name "index.org" base-directory) t)))
    (with-current-buffer buffer
      (set-buffer-modified-p t)
      (save-buffer 0))
    (kill-buffer buffer)))
#+end_src
* Keybindings
Make it easy to publish all or just some of my website:
#+begin_src emacs-lisp
  (with-eval-after-load 'ha-org
    (ha-local-leader 'org-mode-map
      "p"  '(:ignore t :which-key "publishing")
      "p a" '("all" . org-publish-all)
      "p p" '("project" . org-publish-project)))
#+end_src

And let's put a /leader key/ sequence for my favorite file on my website:
#+begin_src emacs-lisp
  (ha-leader
        "f h"  '(:ignore t :which-key "howards")
        "f h i" '("website index" . (lambda ()
                                      (find-file (expand-file-name "index.org" "~/website")))))
#+end_src
* Technical Artifacts :noexport:
Let's =provide= a name so we can =require= it:

#+begin_src emacs-lisp :exports none
(provide 'ha-org-publishing)
;;; ha-org-publishing.el ends here
#+end_src

Before you can build this on a new system, make sure that you put the cursor over any of these properties, and hit: ~C-c C-c~
