| 29 ;; Test syntax related functions. | |
| 30 ;; Right now it tests scan_words using forward-word and backward-word. | |
| 31 ;; See test-harness.el for instructions on how to run these tests. | |

| 33 ;;; Notation | |
| 34 ;; W: word constituent character. | |
| 35 ;; NW: non word constituent character. | |
| 36 ;; -!-: current point. | |
| 37 ;; EOB: end of buffer | |
| 38 ;; BOB: beginning of buffer. | |
| 39 | |
| 40 ;; Algorithm of scan_words is simple. It just searches SW and then | |
| 41 ;; moves to NW. When with MULE, it also stops at word boundary. Word | |
| 42 ;; boundary is tricky and listing all possible cases will be huge. | |
| 43 ;; Those test are omitted here as it doesn't affect core | |
| 44 ;; functionality. | |
