Subject: Discovered pattern that ideally parses any quoting. Brackets highlighting in FSH.
Date: Mon, 30 Jul 2018 09:09:02 +0200	[thread overview]
Message-ID: <CAKc7PVAbwaZr6Pr8weACs7W7E1A6GF5y7QpwRanssYFdGnzSww@mail.gmail.com> (raw)

Hello,
not only (z) can handle quoting, turns out regular pattern with while
loop can do it too:

    while [[ $_mybuf = (#b)[^"{}()[]\\\"'"]#((["({[]})\"'"])|[\\](*))(*) ]]; do
        [[ -n "${match[3]}" ]] && {
            __idx+=${mbegin[1]}+1
            _mybuf="${match[3]:1}" # also skip 1 quoted char
        } || {

the main point is [\\](*). Parentheses are placed in ${match[3]} and
allow to restart processing skipping e.g. a quoted backslash.

The rest is matching braces – it's an example from
Fast-Syntax-Highlighting, it now has ideal brackets highlighting – AND
ALSO ", '. Simple handling of those two quotings allows to switch mode
"in quoting" "outside quoting". That's all. The effect:
