+
or \+
)
If the syntax bit RE_LIMITED_OPS
is set, then Regex doesn't recognize
this operator. Otherwise, if the syntax bit RE_BK_PLUS_QM
isn't
set, then +
represents this operator; if it is, then \+
does.
This operator is similar to the match-zero-or-more operator except that it repeats the preceding regular expression at least once; see Match-zero-or-more Operator, for what it operates on, how some syntax bits affect it, and how Regex backtracks to match it.
For example, supposing that +
represents the match-one-or-more
operator; then ca+r
matches, e.g., car
and
caaaar
, but not cr
.
