ABSTRACT
Let's start with a bit of history: jperl 4.019+1.3 introduced Big5Plus 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, Big5Plus is widely used on mainframe I/O, the personal computer, and the cellular phone. This software treats Big5Plus directly, but doesn't treat Latin-1. Therefore, this software doesn't use UTF8 flag.
Shall we escape from the encode problem?
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 Char::Big5Plus.
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
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 Big5Plus 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.
I learned the following things from the successful software.
Upper Compatibility like Perl4 to Perl5
Maximum Portability like jcode.pl
Handles Raw Big5Plus, Doesn't use UTF8 flag like JPerl
Remains One Interpreter like Encode module
Code Set Independent like Ruby
There's more than one way to do it like Perl itself
Let's make yet another future by JPerl's future.

| JPerl Application Script | Your Script
+---------------------------------------+
| Source Code Filter, Runtime Routine | ex. Char/Big5Plus.pm, Char/Ebig5plus.pm

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.
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.

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.
Escaping Your Script (You do)
You need write 'use Char::Big5Plus;' in your script.
---------------------------------
Before You do
---------------------------------
(nothing) use Char::Big5Plus;
---------------------------------
Escaping Multiple-Octet Code (Char/Big5Plus.pm provides)
Insert chr(0x5c) before @ [ \ ] ^ ` { | and } in multiple-octet of
string in single quote ('', q{}, <<'END' and qw{})
string in double quote ("", qq{}, <<END, <<"END", ``, qx{} and <<`END`)
regexp in single quote (m'', s''', split(''), split(m'') and qr'')
regexp in double quote (//, m//, ??, s///, split(//), split(m//) and qr//)
character in tr/// (tr/// and y///)
ex. Japanese Katakana "SO" like [ `/ ] code is "\x83\x5C" in SJIS
see hex dump
-----------------------------------------
source script "`/" [83 5c]
-----------------------------------------
Here, use SJIS;
hex dump
-----------------------------------------
escaped script "`\/" [83 [5c] 5c]
-----------------------------------------
^--- escape by SJIS software
by the by see hex dump
-----------------------------------------
your eye's "`/\" [83 5c] [5c]
-----------------------------------------
perl eye's "`\/" [83] \[5c]

Multiple-Octet Anchoring Of Regular Expression (Char/Big5Plus.pm provides)
Char/Big5Plus.pm applies multiple-octet anchoring at beginning of regular expression.
--------------------------------------------------------------------------------
Before After
--------------------------------------------------------------------------------
m/regexp/ m/@{Char::Ebig5plus::anchor}(?:regexp).../
--------------------------------------------------------------------------------
Escaping Second Octet (Char/Big5Plus.pm provides)
Char/Big5Plus.pm escapes second octet of multiple-octet character in regular expression.
--------------------------------------------------------------------------------
Before After
--------------------------------------------------------------------------------
m<...`/...> m<...`/\...>
--------------------------------------------------------------------------------
Multiple-Octet Character Regular Expression (Char/Big5Plus.pm provides)
Char/Big5Plus.pm clusters multiple-octet character with quantifier, makes cluster from multiple-octet custom character classes. And makes multiple-octet version metasymbol from classic Perl character class shortcuts and POSIX-style character classes.
--------------------------------------------------------------------------------
Before After
--------------------------------------------------------------------------------
m/...MULTIOCT+.../ m/...(?:MULTIOCT)+.../
m/...[AN-EM].../ m/...(?:A[N-Z]|[B-D][A-Z]|E[A-M]).../
m/...\D.../ m/...@{Char::Ebig5plus::eD}.../
m/...[[:^digit:]].../ m/...@{Char::Ebig5plus::not_digit}.../
--------------------------------------------------------------------------------
Calling 'Char::Ebig5plus::ignorecase()' (Char/Big5Plus.pm provides)
Char/Big5Plus.pm applies calling 'Char::Ebig5plus::ignorecase()' instead of /i modifier.
--------------------------------------------------------------------------------
Before After
--------------------------------------------------------------------------------
m/...$var.../i m/...@{[Char::Ebig5plus::ignorecase($var)]}.../
--------------------------------------------------------------------------------

Un-Escaping \ Of \N, \p, \P and \X (Char/Big5Plus.pm provides)
Char/Big5Plus.pm removes '\' at head of alphanumeric regexp metasymbols \N, \p, \P and \X. By this method, you can avoid the trap of the abstraction.

Escaping File Test Operators (Char/Big5Plus.pm and Char/Ebig5plus.pm provide)
Insert 'Char::Ebig5plus::' instead of '-' of operator.
--------------------------------------------------------------------------
Before After Meaning
--------------------------------------------------------------------------
-r Char::Ebig5plus::r File is readable by effective uid/gid
-w Char::Ebig5plus::w File is writable by effective uid/gid
-x Char::Ebig5plus::x File is executable by effective uid/gid
-o Char::Ebig5plus::o File is owned by effective uid
-R Char::Ebig5plus::R File is readable by real uid/gid
-W Char::Ebig5plus::W File is writable by real uid/gid
-X Char::Ebig5plus::X File is executable by real uid/gid
-O Char::Ebig5plus::O File is owned by real uid
-e Char::Ebig5plus::e File exists
-z Char::Ebig5plus::z File has zero size
-f Char::Ebig5plus::f File is a plain file
-d Char::Ebig5plus::d File is a directory
-l Char::Ebig5plus::l File is a symbolic link
-p Char::Ebig5plus::p File is a named pipe (FIFO)
-S Char::Ebig5plus::S File is a socket
-b Char::Ebig5plus::b File is a block special file
-c Char::Ebig5plus::c File is a character special file
-t -t Filehandle is opened to a tty
-u Char::Ebig5plus::u File has setuid bit set
-g Char::Ebig5plus::g File has setgid bit set
-k Char::Ebig5plus::k File has sticky bit set
-T Char::Ebig5plus::T File is a text file
-B Char::Ebig5plus::B File is a binary file (opposite of -T)
-s Char::Ebig5plus::s File has nonzero size (returns size in bytes)
-M Char::Ebig5plus::M Age of file (at startup) in days since modification
-A Char::Ebig5plus::A Age of file (at startup) in days since last access
-C Char::Ebig5plus::C Age of file (at startup) in days since inode change
--------------------------------------------------------------------------
As of Perl 5.00503, as a form of purely syntactic sugar, you can stack file test operators, in a way that -w -x $file is equivalent to -x $file && -w _ .
if ( -w -r $file ) {
print "The file is both readable and writable!\n";
}
Escaping Function Name (You do)
You need write 'Char::Big5Plus::' at head of function name when you want character- oriented function. See 'Character-Oriented Functions'.

Character-Oriented Functions
Order Of Character
$ord = Char::Big5Plus::ord($string); This function returns the numeric value (ASCII or Big5Plus character) of the first character of $string, not Unicode. If $string is omitted, it uses $_. The return value is always unsigned. If you import ord "use Char::Big5Plus qw(ord);", ord of your script will be rewritten in Char::Big5Plus::ord. Char::Big5Plus::ord is not compatible with ord of JPerl.
Reverse List Or String
@reverse = Char::Big5Plus::reverse(@list); $reverse = Char::Big5Plus::reverse(@list); In list context, this function returns a list value consisting of the elements of @list in the opposite order. 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 Char::Big5Plus qw(reverse);", reverse of your script will be rewritten in Char::Big5Plus::reverse. Char::Big5Plus::reverse is not compatible with reverse of JPerl.
Length By Big5Plus Character
$length = Char::Big5Plus::length($string); $length = Char::Big5Plus::length(); This function returns the length in characters (programmer-visible characters) of the scalar value $string. If $string is omitted, it returns the Char::Big5Plus::length of $_. Do not try to use Char::Big5Plus::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);
Substr By Big5Plus Character
$substr = Char::Big5Plus::substr($string,$offset,$length,$replacement); $substr = Char::Big5Plus::substr($string,$offset,$length); $substr = Char::Big5Plus::substr($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. For bytes, use the substr from built-in Perl functions. An alternative to using Char::Big5Plus::substr as an lvalue is to specify the $replacement string as the fourth argument. This lets you 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: $oldstr = Char::Big5Plus::substr($var, -1, 1, "Curly"); To prepend the string "Larry" to the current value of $var, use: Char::Big5Plus::substr($var, 0, 0, "Larry"); To instead replace the first character of $var with "Moe", use: Char::Big5Plus::substr($var, 0, 1, "Moe"); And, finally, to replace the last character of $var with "Curly", use: Char::Big5Plus::substr($var, -1, 1, "Curly");
Index By Big5Plus Character
$index = Char::Big5Plus::index($string,$substring,$offset); $index = Char::Big5Plus::index($string,$substring); This function searches for one string within another. It returns the character 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 = Char::Big5Plus::index($string, $lookfor, $pos)) > -1) { print "Found at $pos\n"; $pos++; }
Rindex By Big5Plus Character
$rindex = Char::Big5Plus::rindex($string,$substring,$offset); $rindex = Char::Big5Plus::rindex($string,$substring); This function works just like Char::Big5Plus::index except that it returns the character position of the last occurrence of $substring in $string (a reverse Char::Big5Plus::index). The function returns -1 if $substring is not found. $offset, if specified, is the rightmost character position that may be returned. To work your way through a string backward, say: $pos = Char::Big5Plus::length($string); while (($pos = Char::Big5Plus::rindex($string, $lookfor, $pos)) >= 0) { print "Found at $pos\n"; $pos--; }
Byte-Oriented Functions
Chop Byte String
$byte = CORE::chop($string); $byte = CORE::chop(@list); $byte = CORE::chop; This function chops off the last byte of a string variable and returns the byte chopped. The CORE::chop operator is used primarily to remove the newline from the end of an input record, and is more efficient than using a substitution (s/\n$//). If that's all you're doing, then it would be safer to use chomp, since CORE::chop always shortens the string no matter what's there, and chomp is more selective. You cannot CORE::chop a literal, only a variable. If you CORE::chop a @list of variables, each string in the list is chopped: @lines = `cat myfile`; CORE::chop @lines; You can CORE::chop anything that is an lvalue, including an assignment: CORE::chop($cwd = `pwd`); CORE::chop($answer = <STDIN>); This is different from: $answer = CORE::chop($temp = <STDIN>); # WRONG which puts a newline into $answer because CORE::chop returns the byte chopped, not the remaining string (which is in $tmp). One way to get the result intended here is with substr: $answer = substr <STDIN>, 0, -1; But this is more commonly written as: CORE::chop($answer = <STDIN>); In the most general case, CORE::chop can be expressed in terms of substr: $last_byte = CORE::chop($var); $last_byte = substr($var, -1, 1, ""); # same thing Once you understand this equivalence, you can use it to do bigger chops. To CORE::chop more than one byte, use substr as an lvalue, assigning a null string. The following removes the last five bytes of $caravan: substr($caravan, -5) = ""; The negative subscript causes substr to count from the end of the string instead of the beginning. If you wanted to save the bytes so removed, you could use the four-argument form of substr, creating something of a quintuple CORE::chop: $tail = substr($caravan, -5, 5, ""); If no argument is given, the function chops the $_ variable.
Order Of Byte
$ord = CORE::ord($expr); This function returns the numeric value of the first byte of $expr, regardless of "use Char::Big5Plus qw(ord);" exists or not. If $expr is omitted, it uses $_. The return value is always unsigned. If you want a signed value, use unpack('c',$expr). If you want all the bytes of the string converted to a list of numbers, use unpack('C*',$expr) instead.
Reverse List Or Byte String
@reverse = CORE::reverse(@list); $reverse = CORE::reverse(@list); In list context, this function returns a list value consisting of the elements of @list in the opposite order. In scalar context, the function concatenates all the elements of @list and then returns the reverse of that resulting string, byte by byte, regardless of "use Char::Big5Plus qw(reverse);" exists or not.
Index By Byte String
$index = CORE::index($string,$substring,$offset); $index = CORE::index($string,$substring); This function searches for one byte string within another. It returns the position of the first occurrence of $substring in $string. The $offset, if specified, says how many bytes 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 = CORE::index($string, $lookfor, $pos)) > -1) { print "Found at $pos\n"; $pos++; }
Rindex By Byte String
$rindex = CORE::rindex($string,$substring,$offset); $rindex = CORE::rindex($string,$substring); This function works just like CORE::index except that it returns the position of the last occurrence of $substring in $string (a reverse CORE::index). The function returns -1 if not $substring is found. $offset, if specified, is the rightmost position that may be returned. To work your way through a string backward, say: $pos = CORE::length($string); while (($pos = CORE::rindex($string, $lookfor, $pos)) >= 0) { print "Found at $pos\n"; $pos--; }
Un-Escaping bytes::* Functions (Char/Big5Plus.pm provides)
Char/Big5Plus.pm removes 'bytes::' at head of function name.
---------------------------------------
Before After Works as
---------------------------------------
bytes::chr chr Byte
bytes::index index Byte
bytes::length length Byte
bytes::ord ord Byte
bytes::rindex rindex Byte
bytes::substr substr Byte
---------------------------------------
Escaping Built-in Standard Module (Char/Ebig5plus.pm provides)
Char/Ebig5plus.pm does "BEGIN { unshift @INC, '/Perl/site/lib/Char::Big5Plus' }" at head. Store the standard module modified for Char::Big5Plus software in this directory to override built-in standard modules.
Escaping Standard Module Content (You do)
You need copy built-in standard module to /Perl/site/lib/Char::Big5Plus and change 'use utf8;' to 'use Char::Big5Plus;' in its. You need help yourself for now.
Back to and see 'Escaping Your Script'. Enjoy hacking!!

BUGS AND LIMITATIONS
I have tested and verified this software using the best of my ability. However, a software containing much regular expression is bound to contain some bugs. Thus, if you happen to find a bug that's in Char::Big5Plus software and not your own program, you can try to reduce it to a minimal test case and then report it to the following author's address. If you have an idea that could make this a more useful tool, please let everyone share it.
format
Function "format" can't handle multiple-octet code same as original Perl.
chdir
Function chdir() can always be executed with perl5.005.
There are the following limitations for DOS-like system(any of MSWin32, NetWare, symbian, dos).
On perl5.006 or perl5.00800, if path is ended by chr(0x5C), it needs jacode.pl library.
On perl5.008001 or later, perl5.010, perl5.012, perl5.014, perl5.016, if path is ended by chr(0x5C), it needs Win32 module. Chdir succeeds when a short path name can be acquired according to Win32::GetShortPathName(). However, the current directory is a short path name.
see also, Bug #81839 chdir does not work with chr(0x5C) at end of path http://bugs.activestate.com/show_bug.cgi?id=81839
Char::Big5Plus::substr As Lvalue
Char::Big5Plus::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.
Char::Big5Plus::substr($string, 13, 4, "JPerl");
Special Variables $` And $& Need /( Capture All )/
Because $` and $& use $1. ------------------------------------------------------------------------------------------- Before After Works as ------------------------------------------------------------------------------------------- $` Char::Ebig5plus::PREMATCH() CORE::substr($&,0,CORE::length($&)-CORE::length($1)) $PREMATCH Char::Ebig5plus::PREMATCH() CORE::substr($&,0,CORE::length($&)-CORE::length($1)) ${^PREMATCH} Char::Ebig5plus::PREMATCH() CORE::substr($&,0,CORE::length($&)-CORE::length($1)) $& Char::Ebig5plus::MATCH() $1 $MATCH Char::Ebig5plus::MATCH() $1 ${^MATCH} Char::Ebig5plus::MATCH() $1 $' Char::Ebig5plus::POSTMATCH() $' $POSTMATCH Char::Ebig5plus::POSTMATCH() $' ${^POSTMATCH} Char::Ebig5plus::POSTMATCH() $' -------------------------------------------------------------------------------------------
Limitation Of Regular Expression
This software has limitation from \G in multibyte anchoring. On perl5.006, perl5.008, perl5.010, perl5.012, perl5.014 and perl5.016 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.
see also, Bug #89792 \G can't treat over 32,767 octets http://bugs.activestate.com/show_bug.cgi?id=89792
Empty Variable In Regular Expression
Unlike literal null string, an interpolated variable evaluated to the empty string can't use the most recent pattern from a previous successful regular expression.
Limitation Of ?? and m??
Multibyte character needs ( ) which is before {n,m} {n,} {n} * and + in ?? or m??. As a result, you need to rewrite a script about $1,$2,$3,... You cannot use (?: ) ? {n,m}? {n,}? and {n}? in ?? and m??, because delimiter of m?? is '?'.
Look-behind Assertion
The look-behind assertion like (?<=[A-Z]) is not prevented from matching trail octet of the previous multiple-octet code.
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.

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, let's drag out page 402 of the old dusty Programming Perl, 3rd ed. again.
Information processing model with this software
+--------------------------------------------+
| Text strings as Binary strings |
| Binary strings as Text strings |
+--------------------------------------------+
| Not UTF8 Flagged |
+--------------------------------------------+
Ideally, I'd like to achieve these five Goals:
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 Big5Plus designed for combining with old byte-oriented ASCII.
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,Char::Big5Plus +--------------+-------+-------+-------+-------+-------+ | 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 Char::Big5Plus;" on this software, in this case, a new description is necessary.
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.
Goal #4:
Perl should remain one language, rather than forking into a byte-oriented Perl and a character-oriented Perl.
JPerl remains one Perl language by forking to two interpreters. However, the Perl core team did not desire fork of the interpreter. As a result, Perl language forked contrary to goal #4.
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 byte-oriented Perl, a filter program.
And you will get support from the Perl community, when you solve the problem by the Perl script.
Goal #5:
JPerl users will be able to maintain JPerl by Perl.
May the JPerl be with you, always.
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.
