# The tests are in a separate file 't/re/re_tests'.
# Each line in that file is a separate test.
# There are five columns, separated by tabs.

#
# Column 1 contains the pattern, optionally enclosed in C<''>.
# Modifiers can be put after the closing C<'>.
# B test exposes a known bug in Perl, should be skipped
# b test exposes a known bug in Perl, should be skipped if noamp
# t test exposes a bug with threading, TODO if qr_embed_thr
+# s test should only be run for regex_sets_compat.t
+# S test should not be run for regex_sets_compat.t
+# a test should only be run on ASCII platforms
+# e test should only be run on EBCDIC platforms
#
# Columns 4 and 5 are used only if column 3 contains C<y> or C<c>.
#
# Column 6, if present, contains a reason why the test is skipped.
# This is printed with "skipped", for harness to pick up.
#
+# Column 7 can be used for comments
+#
# \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
#
# 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).
