| Test data was taken from the Go distribution, which was in turn taken from the |
| testregex test suite: |
| |
| http://www2.research.att.com/~astopen/testregex/testregex.html |
| |
| Unfortunately, the above link is now dead, but the test data lives on. |
| |
| The LICENSE in this directory corresponds to the LICENSE that the data was |
| originally released under. |
| |
| The tests themselves were modified for RE2/Go. A couple were modified further |
| by me (Andrew Gallant) (only in repetition.dat) so that RE2/Go would pass them. |
| (Yes, it seems like RE2/Go includes failing test cases.) This may or may not |
| have been a bad idea, but I think being consistent with an established Regex |
| library is worth something. |
| |
| After some number of years, these tests were transformed into a JSON format |
| using the fowler-to-json script in this directory, e.g., |
| |
| ./fowler-to-json basic.dat > basic.json |
| |
| which brings them into a sensible structured format in which other tests can |
| be written. |
