# regular expression test set
|
||||
# Lines are at least three fields, separated by one or more tabs. "" stands
|
||||
# for an empty field. First field is an RE. Second field is flags. If
|
||||
# C flag given, regcomp() is expected to fail, and the third field is the
|
||||
# error name (minus the leading REG_).
|
||||
#
|
||||
# Otherwise it is expected to succeed, and the third field is the string to
|
||||
# try matching it against. If there is no fourth field, the match is
|
||||
# expected to fail. If there is a fourth field, it is the substring that
|
||||
# the RE is expected to match. If there is a fifth field, it is a comma-
|
||||
# separated list of what the subexpressions should match, with - indicating
|
||||
# no match for that one. In both the fourth and fifth fields, a (sub)field
|
||||
# starting with @ indicates that the (sub)expression is expected to match
|
||||
# a null string followed by the stuff after the @; this provides a way to
|
||||
# test where null strings match. The character `N' in REs and strings
|
||||
# is newline, `S' is space, `T' is tab, `Z' is NUL.
