2. 你好

3. I‘m charsbar
( 石垣 憲一 ),
from Shibuya.pm,
Tokyo, Japan.

4. I'm glad nothing
is shaking or
swaying this year.

5. Today I'll talk
about something
called CPANTS
and Kwalitee.

6. So, what's
CPANTS?

7. CPAN Testing
Service.

8. One of the QA
tools to keep CPAN
healthy and useful.

9. Actually, we have
another tool of
the same origin.

10. CPAN Testers.

11. What's
different?

12. Both of them do
testing.

13. CPAN Testers test
things module
authors wrote to
assure quality

14. and portability.

15. They're doing
really awesome.

16. Let's see.

17. CPAN Testers
are not perfect,
though.

18. They can't help if
authors don't
write (good) tests.

19. CPANTS tests
things module
authors don't
(or can't) test.

20. Your distribution
is really
extractable?

21. If not,
we can't use it.

22. Does it use
"strict" pragma
in everywhere?

23. If it does,
Perl guesses less.

24. That makes it
easier for people
to collaborate.

25. Does it have
POD tests?

26. If it does,
you'll have
at least readable
documentation.

27. Is it used in
other modules?

28. If it is, someone
thinks it useful.

29. And so on.

30. We have 24
tests, plus 10
extras now to
assure Kwalitee.

31. Some of them are
"nice to have."

32. Some of them are
what annoyed
people in the
past.

33. Broken meta
data.

34. Broken build tool.

35. Version
inconsistency.

36. License issue.

37. You probably
can't remember
all of the past
incidents.

38. CPANTS can.

39. That's one of the
reasons why CPANTS
is important.

40. To attract attention,
CPANTS also offers
a "game".

41. More than 50
authors share the
highest mark
around the world.

42. As for Taiwanese,
Gugod is maintaining
a nice list.

43. Acme::CPANAuthors::Taiwanese

44. With a simple
script, you'll get
a list like this.

45. Most Kwalitative
authors in Taiwan
(with 5 or more dists)

46. Name Kwalitee
DRBEAN 98.214
CINDY 95.833
GSLIN 95.313
CLSUNG 94.583
SHELLING 94.444
SNOWFLY 92.262
AUDREYT 91.837
IJLIAO 91.667
CORNELIUS 90.694
GUGOD 90.126

47. Note that
KWALITEE IS
NOT QUALITY.

48. Kwalitee is not
kind for people
with long track
record.

49. Anyway.

50. You can get a lot of
information from
the CPANTS site.

51. However.

52. CPANTS project
had not been in a
good state for
some time.

53. I wanted to use
its database at
YAPC::Asia,
but I couldn't.

54. So I decided to
set up my own
mirror.

55. cpants.charsbar.org

56. I fixed some of
the major issues
at that time.

57. But there are too
many things to be
done.

58. I've been working
on its
refactoring.

59. As a proof of concept,
I've renewed an
Acme::CPANAuthors site.

60. acme.cpanauthors.org

61. I also tested
queries not to
scan tables
without using
indices.

62. During Perl QA
Hackathon held in
Paris this spring,

63. cpants.perl.org
started redirecting
to my mirror.

64. New metrics is on
the way.

65. Moose and the
likes will be taken
into account soon.

66. There's still lots
to be done.

67. Faster
worker/analyser.
Query tuning.

68. Better UI.

69. JSON API.
Incoming links.

70. More metrics.
More tests.

71. If you find
anything, feel
free to ping me.
