overlapping.toml | Explore in Territory

# NOTE: We define a number of tests where the *match* kind is 'leftmost-first'
# but the *search* kind is 'overlapping'. This is a somewhat nonsensical
# combination and can produce odd results. Nevertheless, those results should
# be consistent so we test them here. (At the time of writing this note, I
# hadn't yet decided whether to make 'leftmost-first' with 'overlapping' result
# in unspecified behavior.)

# This demonstrates how a full overlapping search is obvious quadratic. This
# regex reports a match for every substring in the haystack.
