| * spell.c: code for spell checking |
| * |
| * The basic spell checking mechanism is: |
| * 1. Isolate a word, up to the next non-word character. |
| * 2. Find the word in the hashtable of basic words. |
| * 3. If not found, look in the hashtable with "prewords". These are prefixes |
| * with a non-word character following a word character, e.g., "de-". |
| * 4. If still not found, for each matching a prefix try if the word matches |
| * without the prefix (and with the "chop" string added back). |
| * 5. If still still not found, for each matching suffix try if the word |
| * matches without the suffix (and with the "chop" string added back). |
| * |
| * Matching involves checking the caps type: Onecap ALLCAP KeepCap. |
| * After finding a matching word check for a leadstring (non-word characters |
| * before the word) and addstring (more text following, starting with a |
| * non-word character). |
| * |
| * Why doesn't Vim use aspell/ispell/myspell/etc.? |
| * See ":help develop-spell". |
