Crucial to the proper operation of this interface is that PW and ispell agree on what a word is. For example, "shouldn't" shouldn't be an error, although it contains a non-alphabetic character. Also, the Swedish word "räksmörgås" (shrimp sandwich) should be treated as a single word. So here is my attempt to feed ispell words it will recognize as words. Note that the list of characters that ispell should understand is incomplete. 0. Start ispell in a subprocess with the -a -wåäöÅÄÖ_-' options. 1. Find the longest stretch of characters consisting of characters entirely in the alphabetic set, or one of the characters in this string: åäöÅÄÖ_-´ 2. Trim away leading and trailing characters in this string: _-' 3. Feed the word as "^word\n" to ispell and read the response. 4. If ispell prints a line beginning with '*' or '+', the word is correct, otherwise a dialog with available options is displayed. 5. If the user decides to replace the word, this is done by deleting the original, inserting the replacement and forwarding point to directly after the newly inserted word. Otherwise point is advanced to directly after the original word. 6. The checking sequence is then continued with step 1. Ispell doesn't have a mode in which every line read on stdin is treated as a single word, regardless of character set. I consider this to be a bug in ispell. Before running the checker, PW offers to save the buffer. This is still only a test version.
