# The testregex tests are not wired up yet

The AT&T testregex program is available from:

http://www2.research.att.com/~astopen/testregex/

The so-called "testregex.c 2004-05-31" has a 2010 "what" string, so the
versioning is weird.

The original source code downloaded from the above URL is testregex.c.orig.
testregex.c has a few modification, for example, to support our regex's
"enhanced" mode, as well as pausing if the MallocStackLogging environment
variable is set.

The data files are in the datafiles subdirectory.  Several are part of the
testregex distribution:

basic.dat
categorize.dat
nullsubexpr.dat
leftassoc.dat	(not included, since our implementation is right-associative)
rightassoc.dat
forcedassoc.dat
repetition.dat

The rest are from radars, adapted from the conformance tests, collected from
internet sources or just created to test certain features.

Easy to compile:

% cc testregex.c -o testregex

and easy to run:

% testregex datafiles/union.dat
TEST	testregex union (AT&T Research) 2010-06-10
NOTE	regex
NOTE	unsupported: AUGMENTED,SHELL,CLASS_ESCAPE,COMMENT,DELIMITED,DISCIPLINE,ESCAPE,LEFT,LENIENT,MULTIPLE,MULTIREF,MUSTDELIM,NULL,RIGHT,SHELL_DOT,SHELL_ESCAPED,SHELL_GROUP,SHELL_PATH,SPAN,regnexec,regsubcomp,redecomp
TEST	testregex union, 8 tests, 0 errors

(Some of the locale tests print extra NOTE lines when it switches into a
different locale.)

All datafile should run without error, except:

regex-posix-unittest-1.1.dat
14189743.dat

The first has 8 failures:

TEST	testregex regex-posix-unittest-1.1, 149 tests, 8 errors

This seems to have something to do with repetitions or alterations of ^ and $.
Doesn't look like I ever filed a radar.

The second failure is from the corresponding radar:

Never had a chance to investigate.
