I have an ever-growing document where I keep track of all the small (and sometimes major) changes I want to make to Emacs. Today I picked a random item and had a go at it.
I’m a lousy speller and often misspell words in my comments and git commit messages. I do have fly-spell enabled to catch my mistakes but I would prefer not to make them in the first place. For functions, variable names etc. I have dabbrev-expand and my own home-grown solution based on ctags but nothing similar for words in the English dictionary, so I spent 15 minutes implementing a simple solution.
The picture above shows the command in action trying to complete the word
"dino". I invoked
ido-complete-word-ispell and typed in
"sa"; the list
shows the three remaining completions. I use
ido-vertical-mode to get the vertical representation of
The code for command is shown below. It depends on ido-mode.
(defun ido-complete-word-ispell () "Completes the symbol at point based on entries in the dictionary" (interactive) (let* ((word (thing-at-point 'symbol t)) (boundaries (bounds-of-thing-at-point 'symbol)) (start (car boundaries)) (end (cdr boundaries)) (words (ispell-lookup-words word))) (let ((selection (ido-completing-read "Words: " words))) (if selection (progn (delete-region start end) (insert selection))))))
To add a key-binding for any of the following:
;; To enable it in a specific mode (define-key markdown-mode-map "\M-?" 'ido-complete-word-ispell) ;; To enable it in all modes (global-set-key (kbd "M-?") 'ido-complete-word-ispell)
Simple as that. Now I just need to figure out how to bind the command to a specific key whenever the cursor is inside of a comment or a doc-string.
