你好

I‘m charsbar( 石垣 憲一 ),

from Shibuya.pm, Tokyo, Japan.

I'm glad nothing is shaking or swaying this

year.

Today I'll talk about

something called CPANTS and Kwalitee.

So, what's CPANTS?

CPAN Testing Service.

One of the QA tools to keep

CPAN healthy and useful.

Actually, we have another

tool of the same origin.

CPAN Testers.

What's different?

Both of them do testing.

CPAN Testers test things module

authors wrote to assure quality

and portability.

They're doing really awesome.

Let's see.

CPAN Testers are not perfect,

though.

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

tests.

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

Your distribution is really

extractable?

If not, we can't use it.

Does it use "strict" pragma in everywhere?

If it does, Perl guesses

less.

That makes it easier for people to

collaborate.

Does it have POD tests?

If it does, you'll have

at least readable documentation.

Is it used in other modules?

If it is, someone thinks it useful.

And so on.

We have 24 tests, plus 10 extras now to

assure Kwalitee.

Some of them are "nice to

have."

Some of them are what

annoyed people in the past.

Broken meta data.

Broken build tool.

Version inconsistency.

License issue.

You probably can't remember all of the past

incidents.

CPANTS can.

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

To attract attention, CPANTS also offers

a "game".

More than 50 authors share the highest

mark around the world.

As for Taiwanese, Gugod is

maintaining a nice list.

Acme::CPANAuthors::Taiwanese

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

Most Kwalitative authors in

Taiwan(with 5 or more dists)

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

Note that KWALITEE IS

NOT QUALITY.

Kwalitee is not kind for people with long track

record.

Anyway.

You can get a lot of information

from the CPANTS site.

However.

CPANTS project had not been in a good state for

some time.

I wanted to use its database at

YAPC::Asia, but I couldn't.

So I decided to set up my own

mirror.

cpants.charsbar.org

I fixed some of the major issues

at that time.

But there are too many things

to be done.

I've been working on its refactoring.

As a proof of concept, I've renewed an

Acme::CPANAuthors site.

acme.cpanauthors.org

I also tested queries not to

scan tables without using

indices.

During Perl QA Hackathon held

in Paris this spring,

cpants.perl.org started redirecting

to my mirror.

New metrics is on the way.

Moose and the likes will be taken into

account soon.

There's still lots to be done.

Faster worker/analyser.

Query tuning.

Better UI.

JSON API.

Incoming links.

More metrics.

More tests.

If you find anything, feel

free to ping me.
