I started on that a while ago with some Perl Expect module. The use of the module was a bit cumbersome, but it worked OK. The problem is that you end up just writing out another copy of tab-complete.c in a different language. So, for example, to test else if (Matches4("ALTER", "DOMAIN", MatchAny, "SET")) COMPLETE_WITH_LIST3("DEFAULT", "NOT NULL", "SCHEMA"); the test code would effectively look like test_completion(["ALTER", "DOMAIN", random_string(), "SET"], ["DEFAULT, "NOT NULL", "SCHEMA"]); That's not very interesting, and the regressions are more likely in keeping the test code up to date than in actual behavior changes. I do agree that having some tests would be good, because we're now so used to having tests that reviewing tab completion changes becomes strangely manual. But I don't have a good idea how to structure those tests efficiently. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
