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