I meant the mechanism of SynEdit not SynEdit it self, Let us call "Line
Feeding Highlighting", LFH if you like :P
RegEx used on whale file in memory, but that LFH do it line by line, you can
generate the colored and syntax online without load it in memory, just line
by line.
SynEdit use that way the LFH one.
I doubt SynEdit only uses a line by line method. What happens when a
comment block covers multiple lines. The syntax highlighter needs to
keep track of when the comment block started and continue marking
everything as a comment until it finds the matching closing comment
block tag.
It keeps a general state for the end of each (beginning of next) line:
- eg: currently in comment nested 3
if a change in a line, changes the end-state, then further lines are
scanned, until they match again. In the worst case, that is the rest of
the file; but very often, it doesn't need to look over the current line.
