Elliott Hughes | 5b80804 | 2021-10-01 10:56:10 -0700 | [diff] [blame] | 1 | # This set of tests is not Perl-compatible. It checks on special features |
| 2 | # of PCRE2's API, error diagnostics, and the compiled code of some patterns. |
| 3 | # It also checks the non-Perl syntax that PCRE2 supports (Python, .NET, |
| 4 | # Oniguruma). There are also some tests where PCRE2 and Perl differ, |
| 5 | # either because PCRE2 can't be compatible, or there is a possible Perl |
| 6 | # bug. |
