* Post processing :noexport:
First we need to get all the posts

#+name: collect-posts
#+begin_src emacs-lisp
(setq posts (nreverse
             (directory-files (expand-file-name "../content" default-directory)
                              t "^[0-9]\\{4\\}-[0-9][0-9]-[0-9][0-9]-.+\\.org")))
#+end_src

Then we want to format the content for inclusion.

#+name: post-formatting
#+begin_src emacs-lisp
(defun post-item (file)
  (with-temp-buffer
    (insert-file-contents file)
    (setq keywords (org-collect-keywords '("TITLE" "SUBTITLE" "DATE")))
    (format "+ @@html:<a href='%s.html'>@@ *%s* %s@@html:</a>@@"
            (file-name-base file)
            (cadr (assoc "DATE" keywords))
            (or (cadr (assoc "SUBTITLE" keywords))
                (cadr (assoc "TITLE" keywords))))))
#+end_src

* Output :ignore:

#+begin_src emacs-lisp :noweb yes :results raw :exports results

(mapconcat
 (lambda (p) (post-item p))
 posts
