I tried to leverage the existing test as much as possible, to the point that the new test is pretty hacky. But I think that the result is cute, and it does save us from having to modify the downstream tests (or create unreachable commits, initialize another repository, etc). It looks something like this: --- 8< --- diff --git a/t/t4201-shortlog.sh b/t/t4201-shortlog.sh index 0abe5354fc..566d581e1b 100755 --- a/t/t4201-shortlog.sh +++ b/t/t4201-shortlog.sh @@ -356,6 +356,19 @@ test_expect_success 'shortlog can match multiple groups' ' test_cmp expect actual ' +test_expect_success 'shortlog can match multiple format groups' ' + cat >expect <<-\EOF && + 2 User B <b@xxxxxxxxxxx> + 1 A U Thor <author@xxxxxxxxxxx> + 1 User A <a@xxxxxxxxxxx> + EOF + git shortlog -ns \ + --group="%(trailers:valueonly,separator=%0x00,key=some-trailer)" \ + --group="%(trailers:valueonly,separator=%0x00,key=another-trailer)" \ + -2 HEAD >actual && + test_cmp expect actual +' + test_expect_success 'set up option selection tests' ' git commit --allow-empty -F - <<-\EOF subject --- >8 --- The gross bit there really is the 'separator=%0x00' thing, since the "trailers" pretty format gives us a NL character already. I suppose that you could do something like this on top instead: --- >8 --- diff --git a/t/t4201-shortlog.sh b/t/t4201-shortlog.sh index 566d581e1b..13ac0bac64 100755 --- a/t/t4201-shortlog.sh +++ b/t/t4201-shortlog.sh @@ -363,9 +363,10 @@ test_expect_success 'shortlog can match multiple format groups' ' 1 User A <a@xxxxxxxxxxx> EOF git shortlog -ns \ - --group="%(trailers:valueonly,separator=%0x00,key=some-trailer)" \ - --group="%(trailers:valueonly,separator=%0x00,key=another-trailer)" \ - -2 HEAD >actual && + --group="%(trailers:valueonly,key=some-trailer)" \ + --group="%(trailers:valueonly,key=another-trailer)" \ + -2 HEAD >actual.raw && + grep -v "^$" actual.raw >actual && test_cmp expect actual ' --- 8< --- which I think I prefer slightly. If this is all too hacky for your (or anybody's!) taste, let me know. But I think ultimately this results in a smaller, more easily digestible diff overall. Thanks, Taylor
