=head1 ABSTRACT
Let's start with a bit of history: jperl 4.019+1.3 introduced EUC-JP support.
You could apply chop() and regexps even to complex CJK characters.
JPerl in CPAN Perl Ports (Binary Distributions)
said before,
As of Perl 5.8.0 it is suggested that instead of JPerl (which is
based on a quite old release of Perl) you should just use Perl 5.8.0,
since it can do all that JPerl did, and more.
But was it really so?
In this country, EUC-JP is widely used on mainframe I/O, the personal computer,
and the cellular phone. This software treats EUC-JP directly, but doesn't treat
Latin-1. Therefor there is not UTF8 flag.
A difficult solution makes the problem more difficult.
Shall we escape from the encode problem?
=head1 Yet Another Future Of
JPerl is very useful software. -- Oops, note, this "JPerl" means Japanized or
Japanese Perl, so is unrelated to Java and JVM. Therefore, I named this software
better, fitter EUCJP.
Now, the last version of JPerl is 5.005_04 and is not maintained now.
Japanization modifier WATANABE Hirofumi said,
"Because WATANABE am tired I give over maintaing JPerl."
at Slide #15: "The future of JPerl" of
L<ftp://ftp.oreilly.co.jp/pcjp98/watanabe/jperlconf.ppt>
in The Perl Confernce Japan 1998.
When I heard it, I thought that someone excluding me would maintain JPerl.
And I slept every night hanging a sock. Night and day, I kept having hope.
After 10 years, I noticed that white beard exists in the sock :-)
This software is a source code filter to escape Perl script encoded by EUC-JP
given from STDIN or command line parameter. The character code is never converted
by escaping the script. Neither the value of the character nor the length of the
character string change even if it escapes.
What's this software good for ...
=over 2
=item * Upper Compatibility like Perl4 to Perl5
=item * Maximum Portability like jcode.pl
=item * Handles Raw EUC-JP, No UTF8 flag like JPerl
=item * Remains One Interpreter like Encode module
=item * Code Set Independent like Ruby
=item * There's more than one way to do it like Perl itself
=back
Let's make yet another future by JPerl's future.
=head1 JRE: JPerl Runtime Environment
+---------------------------------------+
| JPerl Application Script | Your Script
+---------------------------------------+
| Source Code Filter, Runtime Routine | ex. EUCJP.pm, Eeucjp.pm
+---------------------------------------+
| PVM 5.00503 or later | ex. perl 5.00503
+---------------------------------------+
A Perl Virtual Machine (PVM) enables a set of computer software programs and
data structures to use a virtual machine model for the execution of other
computer programs and scripts. The model used by a PVM accepts a form of
computer intermediate language commonly referred to as Perl byteorientedcode.
This language conceptually represents the instruction set of a byte-oriented,
capability architecture.
=head1 Basic Idea Of Source Code Filter
I discovered this mail again recently.
[Tokyo.pm] jus Benkyoukai
http://mail.pm.org/pipermail/tokyo-pm/1999-September/001854.html
save as: SJIS.pm
package SJIS;
use Filter::Util::Call;
sub multibyte_filter {
my $status;
if (($status = filter_read()) > 0 ) {
s/([\x81-\x9f\xe0-\xef])([\x40-\x7e\x80-\xfc])/
sprintf("\\x%02x\\x%02x",ord($1),ord($2))
/eg;
}
$status;
}
sub import {
filter_add(\&multibyte_filter);
}
1;
I am glad that I could confirm my idea is not so wrong.
=head1 Software Composition

Rename and install strict.pm_ of this distribution to strict.pm if your system
doesn't have strict.pm.
=head1 Upper Compatibility By Escaping
This software adds the function by 'Escaping' it always, and nothing of the
past is broken. Therefore, 'Possible job' never becomes 'Impossible job'.
This approach is effective in the field where the retreat is never permitted.
Modern Perl/perl can not always solve the problem. Often, it means an
incompatible upgrade part to traditional Perl should be rewound.

=head1 Character Oriented Functions
=over 2
=item * Order Of Character
$ord = EUCJP::ord($string);
This function returns the numeric value ASCII or EUC-JP of the first character
of $string, not Unicode. The return value is always unsigned.
If you import ord "use EUCJP qw(ord);", ord of your script will be rewritten in
EUCJP::ord. EUCJP::ord is not compatible with ord of JPerl.
=item * Reverse List Or String
@reverse = EUCJP::reverse(@list);
$reverse = EUCJP::reverse(@list);
In list context, this function returns a list value consisting of the elements of
@list in the opposite order. The function can be used to create descending
sequences:
for (EUCJP::reverse(1 .. 10)) { ... }
Because of the way hashes flatten into lists when passed as a @list, reverse can
also be used to invert a hash, presuming the values are unique:
%barfoo = EUCJP::reverse(%foobar);
In scalar context, the function concatenates all the elements of LIST and then
returns the reverse of that resulting string, character by character.
If you import reverse "use EUCJP qw(reverse);", reverse of your script will be
rewritten in EUCJP::reverse. EUCJP::reverse is not compatible with reverse of
JPerl.
=item * Length By EUC-JP Character
$length = EUCJP::length($string);
$length = EUCJP::length();
This function returns the length in characters of the scalar value $string. If
$string is omitted, it returns the EUCJP::length of $_.
Do not try to use length to find the size of an array or hash. Use scalar @array
for the size of an array, and scalar keys %hash for the number of key/value pairs
in a hash. (The scalar is typically omitted when redundant.)
To find the length of a string in bytes rather than characters, say simply:
$bytes = length($string);
=item * Substr By EUC-JP Character
$substr = EUCJP::substr($string,$offset,$length,$replacement);
$substr = EUCJP::substr($string,$offset,$length);
$substr = EUCJP::substr($string,$offset);
This function extracts a substring out of the string given by $string and returns
it. The substring is extracted starting at $offset characters from the front of
the string.
If $offset is negative, the substring starts that far from the end of the string
instead. If $length is omitted, everything to the end of the string is returned.
If $length is negative, the length is calculated to leave that many characters off
the end of the string. Otherwise, $length indicates the length of the substring to
extract, which is sort of what you'd expect.
An alternative to using EUCJP::substr as an lvalue is to specify the $replacement
string as the fourth argument. This allows you to replace parts of the $string and
return what was there before in one operation, just as you can with splice. The next
example also replaces the last character of $var with "Curly" and puts that replaced
character into $oldstr:
$oldstr = EUCJP::substr($var, -1, 1, "Curly");
If you assign something shorter than the length of your substring, the string will
shrink, and if you assign something longer than the length, the string will grow to
accommodate it. To keep the string the same length, you may need to pad or chop your
value using sprintf or the x operator. If you attempt to assign to an unallocated
area past the end of the string, EUCJP::substr raises an exception.
To prepend the string "Larry" to the current value of $_, use:
EUCJP::substr($var, 0, 0, "Larry");
To instead replace the first character of $_ with "Moe", use:
EUCJP::substr($var, 0, 1, "Moe");
And finally, to replace the last character of $var with "Curly", use:
EUCJP::substr($var, -1, 1, "Curly");
=item * Index By EUC-JP Character
$index = EUCJP::index($string,$substring,$offset);
$index = EUCJP::index($string,$substring);
This function searches for one string within another. It returns the position of
the first occurrence of $substring in $string. The $offset, if specified, says how
many characters from the start to skip before beginning to look. Positions are
based at 0. If the substring is not found, the function returns one less than the
base, ordinarily -1. To work your way through a string, you might say:
$pos = -1;
while (($pos = EUCJP::index($string, $lookfor, $pos)) > -1) {
print "Found at $pos\n";
$pos++;
}
=item * Rindex By EUC-JP Character
$rindex = EUCJP::rindex($string,$substring,$position);
$rindex = EUCJP::rindex($string,$substring);
This function works just like EUCJP::index except that it returns the position of
the last occurrence of $substring in $string (a reverse index). The function
returns -1 if not $substring is found. $position, if specified, is the rightmost
position that may be returned. To work your way through a string backward, say:
$pos = EUCJP::length($string);
while (($pos = EUCJP::rindex($string, $lookfor, $pos)) >= 0) {
print "Found at $pos\n";
$pos--;

=head1 Environment Variable
This software uses the flock function for exclusive control. The execution of the
program is blocked until it becomes possible to read or write the file.
You can have it not block in the flock function by defining environment variable
SJIS_NONBLOCK.
Example:
SET SJIS_NONBLOCK=1
(The value '1' doesn't have the meaning)

Function "format" can't handle multiple octet code same as original Perl.
=item * EUCJP::substr As Lvalue
EUCJP::substr differs from CORE::substr, and cannot be used as a lvalue.
To change part of a string, you can use the optional fourth argument which is the
replacement string.
EUCJP::substr($string, 13, 4, "JPerl");

For multibyte anchoring,
<\G(?:\x8F[\xA1-\xFE][\xA1-\xFE]|[\x8E\xA1-\xFE][\x00-\xFF]|[^\x8E\x8F\xA1-\xFE])*?> is added.
Result

=item * Limitation Of Regular Expression
This software has limitation from \G in multibyte anchoring. On perl5.006,
perl5.008, perl5.010, perl5.012, and perl5.014, it doesn't match in the place
in which it should match at over 32,767 octets. Moreover, at that time, neither
the error nor warning are displayed.

=item * Modifier /a /d /l And /u Of Regular Expression
The concept of this software is not to use two or more encoding methods at the
same time. Therefore, modifier /a /d /l and /u are not supported.
\d means [0-9] always.

=head1 My Goal
P.401 See chapter 15: Unicode
of ISBN 0-596-00027-8 Programming Perl Third Edition.
Before the introduction of Unicode support in perl, The eq operator
just compared the byte-strings represented by two scalars. Beginning
with perl 5.8, eq compares two byte-strings with simultaneous
consideration of the UTF8 flag.
Information processing model beginning with perl 5.8
+----------------------+---------------------+
| Text strings | |
+----------+-----------| Binary strings |
| UTF8 | Latin-1 | |
+----------+-----------+---------------------+
| UTF8 | Not UTF8 |
| Flagged | Flagged |
+--------------------------------------------+
http://perl-users.jp/articles/advent-calendar/2010/casual/4
You should memorize this figure.
(Why is only Latin-1 special?)
This change consequentially made a big gap between a past script and
new script. Both scripts cannot re-use the code mutually any longer.
Because a new method puts a strain in the programmer, it will still take
time to replace all the in existence scripts.
The biggest problem of new method is that the UTF8 flag can't synchronize
to real encode of string. Thus you must debug about UTF8 flag, before
your script. How to solve it by returning to a past method, I will quote
page 402 of Programming Perl, 3rd ed. again.
Information processing model beginning with this software
+-----------------------------------+
| Octet Strings | aka Binary strings
+-----------------------------------+
| Character Strings | aka Text strings
+-----------------------------------+
| ASCII Compatible Encoding | ex. EUC-JP
+-----------------------------------+
(No UTF8 Flag)
You need not memorize this figure.
Ideally, I'd like to achieve these five Goals:
=over 2
=item * Goal #1:
Old byte-oriented programs should not spontaneously break on the old
byte-oriented data they used to work on.
It has already been achieved by EUC-JP designed for combining with
old byte-oriented ASCII.
=item * Goal #2:
Old byte-oriented programs should magically start working on the new
character-oriented data when appropriate.
Still now, 1 octet is counted with 1 by embedded functions length,
substr, index, rindex and pos that handle length and position of string.
In this part, there is no change. The length of 1 character of 2 octet
code is 2.
On the other hand, the regular expression in the script is added the
multibyte anchoring processing with this software, instead of you.
figure of Goal #1 and Goal #2.
GOAL#1 GOAL#2
(a) (b) (c) (d) (e)
+--------------+-------+-------+-------+-------+-------+
| data | Old | Old | New | Old | New |
+--------------+-------+-------+-------+-------+-------+
| script | Old | Old | New |
+--------------+-------+---------------+---------------+
| interpreter | Old | New |
+--------------+-------+-------------------------------+
Old --- Old byte-oriented
New --- New character-oriented
There is a combination from (a) to (e) in data, script and interpreter
of old and new. Let's add the Encode module and this software did not
exist at time of be written this document and JPerl did exist.
(a) (b) (c) (d) (e)
JPerl Encode,EUCJP
+--------------+-------+-------+-------+-------+-------+
| data | Old | Old | New | Old | New |
+--------------+-------+-------+-------+-------+-------+
| script | Old | Old | New |
+--------------+-------+---------------+---------------+
| interpreter | Old | New |
+--------------+-------+-------------------------------+
Old --- Old byte-oriented
New --- New character-oriented
The reason why JPerl is very excellent is that it is at the position of
(c). That is, it is not necessary to do a special description to the
script to process new character-oriented string.
Contrasting is Encode module and describing "use EUCJP;" on this software,
in this case, a new description is necessary.
=item * Goal #3:
Programs should run just as fast in the new character-oriented mode
as in the old byte-oriented mode.
It is impossible. Because the following time is necessary.
(1) Time of escape script for old byte-oriented perl.
(2) Time of processing regular expression by escaped script while
multibyte anchoring.
=item * Goal #4:
Perl should remain one language, rather than forking into a
byte-oriented Perl and a character-oriented Perl.
JPerl forked the perl interpreter so as not to fork the Perl language.
But the Perl core team might not hope for the perl interpreter's fork.
As a result, the Perl language forked, and the community was reduced
through necessity.
A character-oriented perl is not necessary to make it specially,
because a byte-oriented perl can already treat the binary data.
This software is only an application program of Perl, a filter program.
If perl can be executed, this software will be able to be executed.
And you will get support from the Perl community, when you solve the
problem by the Perl script.
=item * Goal #5:
JPerl users will be able to maintain JPerl by Perl.
May the JPerl be with you, always.
=back
Back when Programming Perl, 3rd ed. was written, UTF8 flag was not born
and Perl is designed to make the easy jobs easy. This software provide
programming environment like at that time.
