| 1083 * EXPLANATION OF THE SYNTAX STATE STACK CACHE | |
| 1084 * | |
| 1085 * To speed up syntax highlighting, the state stack for the start of some | |
| 1086 * lines is cached. These entries can be used to start parsing at that point. | |
| 1087 * | |
| 1088 * The stack is kept in b_sst_array[] for each buffer. There is a list of | |
| 1089 * valid entries. b_sst_first points to the first one, then follow sst_next. | |
| 1090 * The entries are sorted on line number. The first entry is often for line 2 | |
| 1091 * (line 1 always starts with an empty stack). | |
| 1092 * There is also a list for free entries. This construction is used to avoid | |
| 1093 * having to allocate and free memory blocks too often. | |
| 1094 * | |
| 1095 * When making changes to the buffer, this is logged in b_mod_*. When calling | |
| 1096 * update_screen() to update the display, it will call | |
| 1097 * syn_stack_apply_changes() for each displayed buffer to adjust the cached | |
| 1098 * entries. The entries which are inside the changed area are removed, | |
| 1099 * because they must be recomputed. Entries below the changed have their line | |
| 1100 * number adjusted for deleted/inserted lines, and have their sst_change_lnum | |
| 1101 * set to indicate that a check must be made if the changed lines would change | |
| 1102 * the cached entry. | |
| 1103 * | |
| 1104 * When later displaying lines, an entry is stored for each line. Displayed | |
| 1105 * lines are likely to be displayed again, in which case the state at the | |
| 1106 * start of the line is needed. | |
| 1107 * For not displayed lines, an entry is stored for every so many lines. These | |
| 1108 * entries will be used e.g., when scrolling backwards. The distance between | |
| 1109 * entries depends on the number of lines in the buffer. For small buffers | |
| 1110 * the distance is fixed at SST_DIST, for large buffers there is a fixed | |
| 1111 * number of entries SST_MAX_ENTRIES, and the distance is computed. | |
