Selective auto-capitalization in org-buffers

| categories: emacs, orgmode | tags:

I have been using auto-capitalize.el for a short time to automatically capitalize the beginning of sentences. I mostly like what it does, but in org-mode I tend to write short code blocks while still in org-mode, and it is pretty irritating for auto-capitalize to "fix" the capitalization of your code. Of course, I can type C-c ' to edit the block in its native mode, but I do not always want to do that.

Below, I illustrate an approach to turn off auto-capitalize-mode when the cursor is inside a code-block. Basically, we write a function that checks if you are in a src-block, and if auto-capitalize is on, turn it off. If you are not in the code-block, we turn auto-capitalize on if it is not on. Then we hook the function into post-command-hook, which will run it after every emacs command, including cursor movements.

Here is that code:

(defun dwiw-auto-capitalize ()
  (if (org-in-block-p '("src"))
      (when auto-capitalize
        (auto-capitalize-mode -1))
    (unless auto-capitalize
      (auto-capitalize-mode 1))))

(add-hook 'post-command-hook 'dwiw-auto-capitalize)

It works! Now the minor mode turns on and off depending on where the cursor is in my org document.
