1074 /* | |
1075 * EXPLANATION OF THE SYNTAX STATE STACK CACHE | |
1076 * | |
1077 * To speed up syntax highlighting, the state stack for the start of some | |
1078 * lines is cached. These entries can be used to start parsing at that point. | |
1079 * | |
1080 * The stack is kept in b_sst_array[] for each buffer. There is a list of | |
1081 * valid entries. b_sst_first points to the first one, then follow sst_next. | |
1082 * The entries are sorted on line number. The first entry is often for line 2 | |
1083 * (line 1 always starts with an empty stack). | |
1084 * There is also a list for free entries. This construction is used to avoid | |
1085 * having to allocate and free memory blocks too often. | |
1086 * | |
1087 * When making changes to the buffer, this is logged in b_mod_*. When calling | |
1088 * update_screen() to update the display, it will call | |
1089 * syn_stack_apply_changes() for each displayed buffer to adjust the cached | |
1090 * entries. The entries which are inside the changed area are removed, | |
1091 * because they must be recomputed. Entries below the changed have their line | |
1092 * number adjusted for deleted/inserted lines, and have their sst_change_lnum | |
1093 * set to indicate that a check must be made if the changed lines would change | |
1094 * the cached entry. | |
1095 * | |
1096 * When later displaying lines, an entry is stored for each line. Displayed | |
1097 * lines are likely to be displayed again, in which case the state at the | |
1098 * start of the line is needed. | |
1099 * For not displayed lines, an entry is stored for every so many lines. These | |
1100 * entries will be used e.g., when scrolling backwards. The distance between | |
1101 * entries depends on the number of lines in the buffer. For small buffers | |
1102 * the distance is fixed at SST_DIST, for large buffers there is a fixed | |
1103 * number of entries SST_MAX_ENTRIES, and the distance is computed. | |
