Emacs module that generates templates for my blog's static site generator

I wrote a simple emacs module that generates standard templates that I use for my blog's static site generator.

(defun hakyll-site-location ()
"Return the location of the Hakyll files."
"~/Sites/hblog/")

(defun hakyll-new-post (title tags)
"Create a new Hakyll post for today with TITLE and TAGS."
(interactive "sTitle: \nsTags: ")
(let ((file-name (hakyll-post-title title)))
(set-buffer (get-buffer-create file-name))
(markdown-mode)
(insert
(format "---\ntitle: %s\ntags: %s\ndescription: \n---\n\n" title tags))
(write-file
(expand-file-name file-name (concat (hakyll-site-location) "posts")))
(switch-to-buffer file-name)))

(defun hakyll-new-note (title)
"Create a new Note with TITLE."
(interactive "sTitle: ")
(let ((file-name (hakyll-note-title title)))
(set-buffer (get-buffer-create file-name))
(markdown-mode)
(insert (format "---\ntitle: %s\ndescription: \n---\n\n" title))
(write-file
(expand-file-name file-name (concat (hakyll-site-location) "notes")))
(switch-to-buffer file-name)))

(defun hakyll-post-title (title)
"Return a file name based on TITLE for the post."
(concat
(format-time-string "%Y-%m-%d")
"-"
(replace-regexp-in-string " " "-" (downcase title))
".markdown"))

(defun hakyll-note-title (title)
"Return a file name based on TITLE for the note."
(concat
(replace-regexp-in-string " " "-" (downcase title))
".markdown"))


Now, this works, but it could do with DRYing up a little bit, but I don't know enough elisp to do it myself.

• hakyll-new-post and hakyll-new-note are very similar and could do with DRYing up, but I'm not sure how to pass the correct parameter to any refactored function

• I'm hard coding hakyll-site-location. Is there any way that I can request for and store a configuration in my emacs dotfiles?

Any help or pointers to documentation are welcome.

DRY-ing it up:

It looks like variation is in:

• how the filename is obtained

• the contents of the inserted text

• the name of the file to write to.

Also note that if format is given extra arguments not needed by its format-spec that they are ignored.

So you could define a function which takes 3 arguments: the function to call to get the filename to read from, the file-name to write to, and a the format-spec string.

In order to pass a named function to a method you need to quote it as in the example:

(mapcar '1+ '(1 2 3))

If you want to pass an anonymous function to a function you defined it with #'(lambda ...). For example:

(mapcar #'(lambda (x) (1+ x)) '(1 2 3))

Making a configuration setting

I'd suggest changing your hakyll-site-location function into a variable. Use defvar to define it and then you can simply setq it in your emacs dotfiles.
