titular.el 🔠

Emacs has convenient functions for upcasing and downcasing, but why not title casing? This package provides just that. Based on the code originally developed in this blog post.

Installation

This package isn’t on MELPA yet.

If you aren’t using Doom Emacs, the easiest way is probably to use straight.el like this:

(straight-use-package
 '(titular :type git :host github :repo "hungyiloo/titular.el"))

If you are using Doom like me, put this snippet in your packages.el then run doom sync:

(package! titular
  :recipe (:host github :repo "hungyiloo/titular.el"))

Usage & examples

titular-titlecase-dwim will title case the selection region, or the entire line if no region is selected. titular-titlecase-region will strictly title case the selected region only.

This will convert text to title case like:

original text	title cased text
the quick brown fox jumps over the lazy dog	The Quick Brown Fox Jumps Over the Lazy Dog
“To be, or not to be, that is the question”	“To Be, or Not to Be, That Is the Question”
they told me I could be anything I wanted; so I became an emacs lisp package	They Told Me I Could Be Anything I Wanted; So I Became an Emacs Lisp Package

Bonus Doom + evil integration

Put this in your config.el somewhere:

(evil-define-operator my/evil-titlecase-operator (beg end)
  (interactive "<r>")
  (save-excursion
    (set-mark beg)
    (goto-char end)
    (titular-titlecase-dwim)))

(after! evil
  (map! :nv "g`" #'my/evil-titlecase-operator))

Now in normal mode you can use g`` to title case a whole line, or in visual mode g` to title case the actively selected region.

Testing

Execute the bash script test.sh, which runs the ERT tests defined in titular-test.el.
