Posix regular expressions seem to be inconsistent #105

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When used from Google Test, the posix regular expressions do not recognice
digit character class. Specifically, \d expression does not match digits. A
test in gtest-port_test.cc uses [0-9] in order to work. Is this due to the
way we use regex in gtest code or due to the particular implementation we
use? We should investigate.

It's not the way we use the POSIX regexp library.  It turns out that \d and \D
indeeded are not part of the POSIX extended regex syntax.

This is how POSIX extended regex is meant to work.
