Blogging with org-mode for good

I've adapted much of the configuration provided by Thomas Ingram in Building a Emacs Org-Mode Blog so as to manage my blog posts.

FWIW some useful configuration bits (style may be improved):

(setq org-publish-project-alist
      '(
        ("publicwebsite"
         ;; ...
         )
        ("publicwebsiteblog"
         ;; ...
         :sitemap-title "Blog Posts"
         :sitemap-filename "index.org"
         :sitemap-sort-files anti-chronologically
         :sitemap-format-entry (lambda (entry style project)
                                 "Format ENTRY in org-publish PROJECT Sitemap format ENTRY ENTRY STYLE format that includes date."
                                 (let ((filename (org-publish-find-title entry project)))
                                   (if (= (length filename) 0)
                                       (format "*%s*" entry)
                                     (format "{{{timestamp(%s)}}} [[file:%s][%s]]"
                                             (format-time-string "%Y-%m-%d"
                                                                 (org-publish-find-date entry project))
                                             entry
                                             filename))))
         ; HTML5
         :html-doctype "html5"
         :html-html5-fancy t

         :exclude "settings.org\\|blogheaders.org"
         :sitemap-function (lambda (title sitemap)
                             "Prepend pages headers before the posts list"
                             (let* ((title "Blog posts") (subtitle "Posts")
                                    (posts (cdr sitemap))
                                    )
                               (concat (format "#+TITLE: %s\n\n" title)
                                       "\n#+SETUPFILE: ./settings.org\n\n"
                                       "\n#+OPTIONS: toc:nil\n\n"
                                       "\n#+INCLUDE: ./blogheaders.org\n"
                                       (format "\n* %s\n" subtitle)
                                       (org-list-to-org (cons (car sitemap) posts))
                                       )
                               ))
         )
        ;; ...

Here, you'll notice an example of an inline lambda in the sitemap-format-entry, instead of having to define a function name as Thomas did… YMMV.

Also, as I want the blog posts index to be generated with the same presentation as the rest of the blog pages, I need it to contain the following header in the generated index.org sitemap file for that blog section:

#+TITLE: Blog posts

#+SETUPFILE: ./settings.org
#+OPTIONS: toc:nil
#+INCLUDE: ./blogheaders.org

...

So, I've added a sitemap-function, taking inspiration from what Duncan Mac-Vicar P. is doing in duncan/archive-sitemap-function (see http://www.mac-vicar.eu/posts/2019-09-03-migrating-from-jekyll-to-org/index.html).
