| 1070 * EXPLANATION OF THE SYNTAX STATE STACK CACHE | |
| 1071 * | |
| 1072 * To speed up syntax highlighting, the state stack for the start of some | |
| 1073 * lines is cached. These entries can be used to start parsing at that point. | |
| 1074 * | |
| 1075 * The stack is kept in b_sst_array[] for each buffer. There is a list of | |
| 1076 * valid entries. b_sst_first points to the first one, then follow sst_next. | |
| 1077 * The entries are sorted on line number. The first entry is often for line 2 | |
| 1078 * (line 1 always starts with an empty stack). | |
| 1079 * There is also a list for free entries. This construction is used to avoid | |
| 1080 * having to allocate and free memory blocks too often. | |
| 1081 * | |
| 1082 * When making changes to the buffer, this is logged in b_mod_*. When calling | |
| 1083 * update_screen() to update the display, it will call | |
| 1084 * syn_stack_apply_changes() for each displayed buffer to adjust the cached | |
| 1085 * entries. The entries which are inside the changed area are removed, | |
| 1086 * because they must be recomputed. Entries below the changed have their line | |
| 1087 * number adjusted for deleted/inserted lines, and have their sst_change_lnum | |
| 1088 * set to indicate that a check must be made if the changed lines would change | |
| 1089 * the cached entry. | |
| 1090 * | |
| 1091 * When later displaying lines, an entry is stored for each line. Displayed | |
| 1092 * lines are likely to be displayed again, in which case the state at the | |
| 1093 * start of the line is needed. | |
| 1094 * For not displayed lines, an entry is stored for every so many lines. These | |
| 1095 * entries will be used e.g., when scrolling backwards. The distance between | |
| 1096 * entries depends on the number of lines in the buffer. For small buffers | |
| 1097 * the distance is fixed at SST_DIST, for large buffers there is a fixed | |
| 1098 * number of entries SST_MAX_ENTRIES, and the distance is computed. | |
