S2 has a special type of string that is
delimited by three quotes, which allows you to include quotes and
double quotes in the string, unescaped. (This is useful for
quote-heavy stuff like HTML.) It looks like this:
"""this is a "cool string" in which quotes - "" need not be escaped"""
Anyway, I'm trying to figure out how to fit this into my syntax
highlighting. I guess my biggest problem is that I do not understand
the canonical string region declaration; this one is from c.vim:
syn region s2String start=+L\="+ skip=+\\\\\|\\"+ end=+"+
What in the world do those pluses mean? And that queue of
backslashes? I don't understand how those specifications follow
pattern syntax.
It's just equivalent to
... start=/L\="/ skip=/\\\\\|\\"/ end=/"/
... [EMAIL PROTECTED]"@ [EMAIL PROTECTED]|\\"@ end=@"@
... start=;L\="; skip=;\\\\\|\\"; end=;";
Any delimiter can be used in place of '/' to delimit regexp!
BTW it's also true about :s/// command; all of the following mean the same:
:s;from;to;
:[EMAIL PROTECTED]@to@
:s+from+to+
(except when separattor occurs inside the regexp and replacement).
Backslashes mean to handle the "\n\\\"" C notation. Maybe you don't need it,
depending of whether S2 handlesh backslas inside quoted sring
specially or not.
