Hi Vagrant,

If I remember correctly the previous discussion, Debian uses an external
tool for spellchecking.  Here, the patch uses a list of “common”
mistakes.  It is seems an easy good start. :-)


> +  (define (check-description-typo description typo correction)

Instead, I would use a list of alist ’typo-corrections’ as argument.
For instance,

--8<---------------cut here---------------start------------->8---
(define (check-description-typo description typo-corrections)
  (for-each
   (match-lambda
     ((typo . correction)
      (if (string-contains description typo)
          (list
           (make-warning ...))
          '())))
   typo-corrections))
--8<---------------cut here---------------end--------------->8---

And the call reads,

            (check-description-typo description '(("This packages" . "This package")))

which allows easily to add new pattern; such as,

        '(("This packages" . "This package")
          ("this packages" . "this package")
          ("This modules" . "This module"))

Then, as a second step, depending on the patterns listed, let see if
there is a pattern inside these patterns. ;-) (Check both capitalize and
lower-case, etc.)


Cheers,
simon
