There was __idx assign missing, and I fine-tuned readibility, so final version:
_mybuf="A\AB'A'C" #input
while [[ $_mybuf = (#b)[^ABC\"\'\\]#(([ABC\"\'])|[\\](*))(*) ]]; do
[[ -n "${match[3]}" ]] && {
__idx+=${mbegin[1]}+1
_mybuf="${match[3]:1}" # also skip 1 quoted char
} || {
__idx+=${mbegin[1]}
[[ -z "$__quoting" ]] && {
if [[ "${match[1]}" = [ABC] ]]; then
echo "Got ${match[1]}"
fi
}
# Toggle quoting
[[ "${match[1]}" = \" && "$__quoting" != \' ]] && {
[[ "$__quoting" = \" ]] && __quoting= || __quoting=\";
}
[[ "${match[1]}" = \' && "$__quoting" != \" ]] && {
[[ "$__quoting" = \' ]] && __quoting= || __quoting=\';
}
# The last (*) in the pattern, i.e. remaining
# string, to become next input to while
_mybuf="${match[4]}"
}
done
