#!./perl

# 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<'>.
#
# Column 2 contains the string to be matched.
#
# Column 3 contains the expected result:
# 	y	expect a match
# 	n	expect no match
# 	c	expect an error
#	T	the test is a TODO (can be combined with y/n/c)
#	M	skip test on miniperl (combine with y/n/c/T)
#	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
#
# Columns 4 and 5 are used only if column 3 contains C<y> or C<c>.
#
# Column 4 contains a string, usually C<$&>.
#
# 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.
#
# 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
# 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 re/pat.t instead.
#
# Note that the inputs get passed on as "m're'", so the re bypasses the lexer.
# This means this file cannot be used for testing anything that the lexer
# handles; in 5.12 this means just \N{NAME} and \N{U+...}.
#
# 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).
