Tags as labels for the blog is a welcome feature.

That's an understatement.  Publishing from org to blogger is nearly
transparent and takes only seconds to confirm the information
(e.g. title, labels).  It is a treat to use org-googlecl.  Thank you
Richard.

Example of providing auto input to a waiting shell process

In this instance pipes "y" to the called process to confirm we want the blog deleted.

(let ((delcommand  (format "yes y | google blogger delete --blog '%s'  --title '%s'"  googlecl-blogname  btitle)))
                      (message "Delete command is : %s" delcommand)
                      (call-process-shell-command delcommand))

Now org-googlecl supports deleting of existing entries

If you try to blog a title that exists you can examine it and/or
delete prior to blogging the new version. See link in footer for git
files.

(if googlecl-blog-exists
   (with-temp-buffer
     (let* ((blogrc (call-process-shell-command  (concat "google blogger  list --blog '" googlecl-blogname "' --title '" btitle "' url") nil (current-buffer)))
          (blogurl (buffer-string)))
       (if (not (zerop(length blogurl)))
           (progn
             (if (y-or-n-p (concat "Blog entry exists :" blogurl ". View existing?"))
                 (browse-url (nth 0 (org-split-string blogurl))))
             (setq blogurl (nth 0 (org-split-string blogurl)))
             (if (y-or-n-p "Delete existing blog entry?")
                 (let ((delcommand  (format "yes y | google blogger delete --blog '%s'  --title '%s'"  googlecl-blogname  btitle)))
                   (message "Delete command is : %s" delcommand)
                   (call-process-shell-command delcommand))))))))

Moving my dot files into org chunks and blogging them

The influx of code chunks to the blog are because I am moving my init
files to smaller org chunks. I think this could be helpful to not
only others but surely myself further down the road.

dotemacs on github

My emacs files are now in github following a request for the files in
raw format. The main entry point is init.el at master from rileyrg's emacs - GitHub which processes emacs-init.org at master from rileyrg's emacs - GitHub to produce emacs-init.el at master from rileyrg's emacs - GitHub. Custom variables are stored in custom.el at master from rileyrg's emacs - GitHub. Not all of the things loaded by my init
files are in git. Some you will have to track down and install as
dependencies.

Gnus group line pretty printing with UNREAD indicators
