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.
|
||
|
|
|
||
|
|
The full list of flags:

|

- placeholder, does nothing

b RE is a BRE, not an ERE
|

& try it as both an ERE and a BRE

C regcomp() error expected, third field is error name

m ("mundane") REG_NOSPEC
|

s REG_NOSUB (not really testable)

|
# REG_STARTEND (see below)
|
||
|
|
p REG_PEND
|
||
|
|
|
||
|
|
For REG_STARTEND, the start/end offsets are those of the substring
|
||
|
|
enclosed in ().
