# The tests are in a separate file 't/op/re_tests'.
# Each line in that file is a separate test.
# There are five columns, separated by tabs.
# Column 5 contains the expected result of double-quote
# interpolating that string after the match, or start of error message.
#
+# Column 6, if present, contains a reason why the test is skipped.
+# This is printed with "skipped", for harness to pick up.
+#
# \n in the tests are interpolated, as are variables of the form ${\w+}.
#
+# Blanks lines are treated as PASSING tests to keep the line numbers
+# linked to the test number.
+#
# If you want to add a regular expression test that can't be expressed
# in this format, don't add it here: put it in op/pat.t instead.
+#
+# Note that columns 2,3 and 5 are all enclosed in double quotes and then
+# evalled; so something like a\"\x{100}$1 has length 3+length($1).
