Spellchecking provided by Company

company-spell

An Emacs company-mode backend for any terminal spellchecker. Unlike company-ispell which requires a plaintext dictionary, this just pipes results from a spellchecking command on your computer into company-mode. I have not run into any notable performance issues with this approach.

It will automatically run on any buffer that has a major mode derived from text-mode, which includes almost all modes meant for human writing.

Instructions

1. Ensure a terminal spellchecker is installed (aspell, hunspell, ispell, etc)
2. Clone this repo and load it like this:

(add-to-list 'load-path "~/.emacs.d/local/company-spell")
(require 'company-spell)

3. Once loaded:

(add-to-list 'company-backends  'company-spell t)

4. Optionally, set a spellchecker that isn't the default value of aspell:

(setf company-aspell-command "hunspell")
;; or
(setf company-aspell-command "ispell")

5. You can further customize your results by setting custom args (only -a is enabled by default). For instance, search via "soundslike":

(setf company-spell-args "-a soundslike")
