16 Using with flyspell-prog-mode

Strings and comments can be checked for spelling mistakes. There is a standard Emacs mode for this purpose, flyspell-prog-mode, that can be enabled in Haskell buffers. Spelling errors are underlined using squiggly red lines.

Documentation for flyspell-prog-mode can be found in See (emacs)Spelling. Here we point to a couple of useful keybindings:

• M-$ - Check and correct spelling of the word at point (ispell-word).
• digit - Replace the word, just this time, with one of the displayed near-misses. Each near-miss is listed with a digit; type that digit to select it.
• SPC - Skip this word—continue to consider it incorrect, but don’t change it here.

To enable spell checking of strings and comments add this line to your ~/.emacs file:

(add-hook 'haskell-mode-hook 'flyspell-prog-mode)
