キタ━━(゚∀゚)━━ッ!!
Welcome to Japan
はい、ここで拍手! m(_ _)m
Yet Another Perl Conference
Where is
the Next
Conference?
次のカンファレンスはどこでやる?
Where is this place?
“waterfall”
滝
Come on in, the water's fine.
Waterfalls:
Not just for tourists.
ウォーターフォールは:
観光客だけのものじゃなくって
for most programmers! (except hackers)
職業プログラマにも必要ですから!
落ちるな危険
Waterfall Model
開発は
滝底に落ちない
ように気をつける…
デスマーチになるかも
Escape
a water grave
デスマーチから抜け出そう!

Talks#1: Ruby On Snails
新フレームワークで開発を遅くしよう
Slow down development
with this new framework
by Dave Thomas and Mike Clark
Waterfall 2006 Conference
Location
Niagara Falls, NY
ナイアガラの滝(ニューヨーク州)で開催
Date

開催日は4月1日
http://www.waterfall2006.com/
the day after
tomorrow !
Talks#2: Pair Managing
Is not Pair Programming
ペアプロじゃなくって、ペア管理
1人のプログラマにマネージャが2人
Two Managers per Programmer
☻
☻
by Jim Highsmith
☹
#3: Unfactoring from Patterns
読みにくいコードで職を守る
Job Security through Unreadability
by Joshua Kerievsky
You don’t need to
Unreadability?
Perl5?
Unreadable
Perl5 code
読みにくいPerlプログラム
Sorry, Damian…
and the other healthy nonsmokers
Prescription(処方箋)
a Programming
Language, too
プログラミング言語も同様に
Unreadable
Perl5→
読みにくいプログラムを量産し続けるPerl5
Sigils problem on Perl5
scalar
------$s
array hash
------ ------@a
%h
$$s
$a[0]
$h{'?'}
$s->foo
☹
☹
Sigils rule on Perl6
scalar
------$s
$$s
$s.foo
☺
array
-----@a
@a[0]
@a.foo
hash
------%h
%h<?>
%h.foo
Readable
Perl6!
読みやすいプログラムを書けるPerl6になる!
O’REILLY
NOT’REALLY
looks like…
Unreadable
JAPH!
解読困難なJAPHに似ているかも?
But, it’s
Okay…
でも、そんなことはどうでもいいんです
because…
なぜなら・・・
Job Security
through
Unreadability
読みにくいコードで職を守れるから(笑)
Good job!

Brainwashed by Ruby

Perl厨にRubyを使わせる
I have yet another idea
that every Perl mongers
want to use Ruby…
Perl厨にRubyを使わせる
もっと良い方法があります
The Best solution(最適解)
Steal the buttons of "$" and ";"
from Perl mongers' keyboard.
キーボードから「$」と「;」を盗めばいいんだ
most Perl mongers
will have
no alternative
but to use Ruby
そうすればPerl厨は仕方なくRubyを使う
It seems
Okay…
一見良さそうに見える…
けど
Yet another Perl lover
本当にPerlを愛する人はこんなプログラムを書き始める:
#!/usr/bin/perl -w
q chr uc and print chr ord uc qw q y q and
print chr ord uc q map m and print chr oct
ord q qx eq and print chr ord uc q oct do and
print chr oct ord uc q chr lc and print chr oct
ord uc q chr uc and print chr ord uc q map m
and print chr ord qw q s q and print chr ord
q tie gt and print chr ord q each le
→ print ”YAPC::Asia”;
予約語とスペースだけでプログラミング
Programming Perl with
only
reserved keywords
and white spaces!
記号を一切使わずに!
without symbols!
Reserved keywords(予約語)
■ Operators… (38)
lt gt le ge eq ne cmp not and or xor if else elsif while for foreach continue goto last
local map my next redo require return use tr y s m q qq qr qw qx x
■ Built-in functions… (182)

But JAPH should not
be written by
manually
でも、JAPHは手で書くもんじゃないよね
No coding

書かないのが最善
♨ ppencode ☣
So I wrote “ppencode”.
で、ppencodeというプログラムを書いてみました
Demoをどうぞ(Ajax風味)
http://namazu.org/~takesako/ppencode/demo.html
ppencode is a JAPH generator
I wrote only gen_ppencode.pl
♨
ppencode
(perl, JavaScirpt)
programming
autogen
gen_ppencode
(6KB)
autogen
input
a message
(8bit ok)
JAPH
output
No coding
