/-- This set of tests is not Perl-compatible. It checks on special features
|
||
|
|
of PCRE's API, error diagnostics, and the compiled code of some patterns.
|
||
|
|
It also checks the non-Perl syntax the PCRE supports (Python, .NET,
|
||
|
|
Oniguruma). Finally, there are some tests where PCRE and Perl differ,
|
||
|
|
either because PCRE can't be compatible, or there is a possible Perl
|
||
|
|
bug.
|
||
|
|
|
||
|
|
NOTE: This is a non-UTF set of tests. When UTF support is needed, use
|
||
|
|
test 5, and if Unicode Property Support is needed, use test 7. --/
