Title:
Mawk does not support Posix character classes in expressions
Status in mawk package in Ubuntu:
Confirmed
Status in mawk package in Debian:
Confirmed
Bug description:
Binary package hint: mawk
Mawk does not support Posix character classes, such as [:upper:] and
[:lower:], in regular expressions. This makes it more difficult to
write portable Awk scripts (since [A-Z] match lower-case characters in
Gawk using non-English locales)
E.G.:
$ echo x | mawk '/[[:lower:]]/'
$ echo x | gawk '/[[:lower:]]/'
x
$
Attached is a patch to fix this issue.
