Despite having bumped it from 2.x to 3.x yesterday, I'm calling v4.0 on blogmore.el today. There's a good reason for this though. While tinkering with some of the configuration yesterday, and also answering a configuration question last night, I realised that it made sense to make some of the internals into public utility functions.

Now, sure, Emacs Lisp doesn't really have internals in the private function sense, but I've always liked the approach that a package-- prefix communicates "internal, might go away" vs package- which tells me "this is a stable part of the API of this package". With this in mind I've always tried to write my code using this convention. I did this with blogmore.el too and a lot of the code had the blogmore-- prefix.

There's plenty of code in there that someone might want to make use of, if they wanted to add their own commands, or do fun things with the configuration. So with this in mind I've "promoted" a bunch of code to being "public" and, in that case, I feel this deserves another major version bump¹.

Things that are now part of the "public" interface include:

• blogmore-clean-time-string
• blogmore-get-frontmatter
• blogmore-remove-frontmatter
• blogmore-set-frontmatter
• blogmore-slug
• blogmore-toggle-frontmatter
• blogmore-with-post

Each one is documented via its docstring (just a quick Ctrl+h f function-name RET away) and hopefully is pretty self-explanatory.

blogmore-with-post is especially handy as it provides a quick and easy way of pulling information from a post file. So something like this:

(blogmore-with-post "~/write/davep.github.com/content/posts/2026/04/2026-04-05-blogmore-el-v3-1.md"
  (list
   (blogmore-get-frontmatter "title")
   (blogmore-get-frontmatter "date")))

resulting in:

("blogmore.el v3.1" "2026-04-05 20:04:44+0100")

Meaning that this snippet from yesterday's post:

(with-temp-buffer
  (insert-file-contents-literally file)
  (parse-iso8601-time-string
   (blogmore--clean-time-string (blogmore--get-frontmatter-property "date"))))

becomes:

(blogmore-with-post file
  (parse-iso8601-time-string
   (blogmore-clean-time-string (blogmore-get-frontmatter "date"))))

Not massively different, but it reads better and now all the calls are to the "public API" of the package.

Not all the changes are "promoted internals". I've also added a blogmore-remove-tag command (and also added it to the transient menu).

I've also changed the way that blogmore-add-tag works so that, now, if it's called from the transient, it immediately goes back to the tag input prompt, allowing for another tag to be immediately selected (you can quit out of this with Ctrl+g). Removal of a tag works in a similar way, making things a lot quicker.

I've also added some extra tests too, which makes it even easier for me to make future changes with confidence. The more I work with it the more I appreciate that ERT is available.
