Subject: mawk: mawk's regexps don't conform to POSIX

Date: 15 Jun 2005 21:13:28 +0300

Package: mawk
Version: 1.3.3a-11
Severity: normal
Tags: patch

Hi.
As you may know, mawk's internal regular expression engine
doesn't support character classes and therefore is not conformant
to POSIX regexp.

I've written patch which builds mawk with external regexp engine.
There are lots of different regexp engines world-wide.
You can use any of them
On most modern systems system-wide regexp engine also conforms to POSIX.
As a result mawk conforms to POSIX regexp, if you build
it with appropriate regexp engine like this.

# regexec/regcomp functions from libc will be used
./configure && make

# TRE implementation will be used
CFLAGS='-O3 -I/usr/include/tre' LDFLAGS='-ltre' ./configure && make

Whether UTF-8 support is provided or not
also depends on external regexp library.

If you find bugs in it, let me know.

The patch is here.

Do not forget to run antoconf
to create new 'configure' script.

Do not forget to run 'autoconf'
before configuring mawk.
autoconf2.13 works fine.

Version: 1.3.4.20200120-1~exp1

As the previous discussion on this bug report seems to have concluded
that the problem was fixed in new upstream version I'm closing this
bug using the current version available in experimental as of now.
Please feel free to reopen and describe the current status if you
find the problem is not fixed in the new version.

Regards,
Andreas Henriksson
