DESCRIPTION

  This software is a source code filter, a transpiler-modulino.

  Perl is said to have been able to handle Unicode since version 5.8. However,
  unlike JPerl, "Easy jobs easy" has been lost. (but we have got it again :-D)

  In Shift_JIS and similar encodings(Big5, Big5-HKSCS, GB18030, GBK, Sjis, UHC)
  have any DAMEMOJI who have metacharacters at second octet. Which characters
  are DAMEMOJI is depends on whether the enclosing delimiter is single quote or
  double quote.

  This software escapes DAMEMOJI in your script, generate a new script and
  run it.

  There are some MBCS encodings in the world.
  in Japan since 1978, JIS C 6226-1978,
  in China since 1980, GB 2312-80,
  in Taiwan since 1984, Big5,
  in South Korea since 1991, KS X 1002:1991, and more.
  Even if you are an avid Unicode proponent, you cannot change this fact. These
  encodings are still used today in most areas except the world wide web.

  This software ...
  * supports MBCS literals in Perl scripts
  * supports Big5, Big5-HKSCS, EUC-JP, GB18030, GBK, Sjis, UHC, UTF-8, and WTF-8
  * does not use the UTF8 flag to avoid MOJIBAKE
  * escapes DAMEMOJI in scripts
  * handles raw encoding to support GAIJI
  * adds multibyte anchoring to regular expressions
  * rewrites character classes in regular expressions to work as MBCS codepoint
  * supports special variables $`, $&, and $'
  * does not change features of octet-oriented built-in functions
  * lc(), lcfirst(), uc(), and ucfirst() convert US-ASCII only
  * codepoint range by hyphen of tr/// and y/// support US-ASCII only
  * You have to write mb::* subroutines if you want codepoint semantics

  Let's enjoy MBSC scripting in Perl!!

MBCS subroutines provided by this software

  This software provides traditional feature "as was." The new MBCS features
  are provided by subroutines with new names. If you like utf8 pragma, mb::*
  subroutines will help you. On other hand, If you love JPerl, those
  subroutines will not help you very much. Traditional functions of Perl are
  useful still now in octet-oriented semantics.

  Sometimes "compatibility" means "compromise." In that case, "best compatibility" means
  "most useful compromise." That's what mb::index_byte() and mb::rindex_byte() are.
  But sorry for the long name.

      system(qq{ $mb::PERL MBCS_perl_script.pl });   # for MBCS script
  • $mb::ORIG_PROGRAM_NAME

      if ($0 =~ /-x64\.pl\z/) { ... }                # had been write this...

What are DAMEMOJI?

  In single quote, DAMEMOJI are double-byte characters that include the
  following metacharacters ('', q{}, <<'END', qw{}, m'', s''', split(''),
  split(m''), and qr'')
  ------------------------------------------------------------------
  hex   character as US-ASCII
  ------------------------------------------------------------------
  5C    [\]    backslashed escapes

How to escape 2nd octet of DAMEMOJI

  ex. Japanese KATAKANA "SO" like [ `/ ] code is "\x83\x5C" in Sjis
 
                  see     hex dump
  -----------------------------------------
  source script   "`/"    [83 5c]

Command-line Wildcard Expansion on Microsoft Windows

cmd.exe that is default command shell of Microsoft Windows doesn't expand wildcard arguments supplied onto command line. But this software helps it.

  # @ARGV wildcard globbing
  if ($OSNAME =~ /MSWin32/) {
      my @argv = ();
      for (@ARGV) {
  
          # has space
          if (/\A (?:$x)*? [ ] /oxms) {
              if (my @glob = mb::dosglob(qq{"$_"})) {
                  push @argv, @glob;
              }
              else {
                  push @argv, $_;
              }
          }
  
          # has wildcard metachar
          elsif (/\A (?:$x)*? [*?] /oxms) {
              if (my @glob = mb::dosglob($_)) {
                  push @argv, @glob;
              }
              else {
                  push @argv, $_;
              }
          }
  
          # no wildcard globbing
          else {
              push @argv, $_;
          }
      }
      @ARGV = @argv;
  }

Yet Another Future of Multibyte Perl

JPerl is very useful software. -- Oops, note, this "JPerl" means "Japanized Perl" or "Japanese Perl". Therefore, it is unrelated to JPerl of the following.

 jperl -  Jamie's PERL scripts for bioinformatics
 https://code.google.com/archive/p/jperl/

 Jon Perl jperl
 https://github.com/jperl

Now, the last version of JPerl is 5.005_04 and is not maintained now.

Japanization maintainer WATANABE Hirofumi said,

  "Because WATANABE am tired I give over maintaing JPerl."

at Slide #15: "The future of JPerl" in "jperlconf.ppt" on The Perl Confernce Japan 1998. And he taught us on [Tokyo.pm] jus Benkyoukai at 1999-09-09,

  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;

(Unfortunately, Filter::Util::Call module requires Perl 5.6, so I couldn't use it on Perl 5.00503 that's my home.)

I am excited about this software and Perl's future --- I hope you are too.

DEPENDENCIES

  This mb.pm modulino requires perl5.00503 or later to use. Also requires 'strict'
  module. It requires the 'warnings' module, too if perl 5.6 or later.

Fatal Bugs Unavoidable

For several reasons, we were unable to achieve the following features:

  • chdir() on Microsoft Windows

    Function chdir() cannot work if path is ended by chr(0x5C).

      This problem is specific to Microsoft Windows. It is not caused by the mb.pm
      modulino or the perl interpreter.
      
      # chdir.pl
      mkdir((qw( `/ ))[0], 0777);
      print "got=", chdir((qw( `/ ))[0]), " cwd=", `cd`;
      
      C:\HOME>perl5.00503.exe chdir.pl
        GOOD ==> got=1 cwd=C:\HOME\`/
      
      C:\HOME>strawberry-perl-5.8.9.5.exe chdir.pl
        BAD ==> got=1 cwd=C:\HOME

    This is a lost technology in this century.

      # suggested module name
      use mb::WinDir; # supports for all MBCS on Microsoft Windows
      my $wd = mb::WinDir->new('`/');
      $wd->chdir('..');
      $wd->open(my $fh, ...);
  • Look-behind Assertion

    The look-behind assertion like (?<=[A-Z]) or (?<![A-Z]) are not prevented from matching trail octet of the previous MBCS codepoint.

    Please give us your good hack on this.

  • Empty Variable in Regular Expression

    An empty literal string as regexp means empty string. Unlike original Perl, if 'pattern' is an empty string, the last successfully matched regexp is NOT used. Similarly, empty string made by interpolated variable means empty string, too.

Small Bugs Avoidable

You can avoid the following bugs with little hacks.

  • Hyphen of tr/// Supports US-ASCII Only

    Supported ranges of tr/// and y/// by hyphen are US-ASCII only.

  • Special Variables $` and $& need m/( Capture All )/

    If you use the special variables $ ` or $&, you must enclose the entire regular expression in parentheses. Because $` and $& needs $1 to implement its.

      ----------------------------------------------------------------------------------------------------------------------
      in your script      after m//, works as                         after s///, works as
      ----------------------------------------------------------------------------------------------------------------------
      $`                  CORE::substr($&, 0, -CORE::length($1))      $1
      ${`}                CORE::substr($&, 0, -CORE::length($1))      $1
      $PREMATCH           CORE::substr($&, 0, -CORE::length($1))      $1
      ${^PREMATCH}        CORE::substr($&, 0, -CORE::length($1))      $1
      $&                  $1                                          CORE::substr($&, CORE::length($1))
      ${&}                $1                                          CORE::substr($&, CORE::length($1))
      $MATCH              $1                                          CORE::substr($&, CORE::length($1))
      ${^MATCH}           $1                                          CORE::substr($&, CORE::length($1))
      ----------------------------------------------------------------------------------------------------------------------

    In the past, Perl scripts with special variables $` and $& had a problem with slow execution. Both that era and today, capturing by parentheses works well.

  • Return Value from tr///s

    tr/// (or y///) operator with /s modifier returns 1 always. If you need right number, you can use mb::tr().

      $var1 = 'AAA';
      $got = $var1 =~ tr/A/1/s; # works as $got = $var1 =~ s{[\x00-\xFF]*}{mb::tr($&,q/A/,q/1/,'sr')}e;
        BAD ==> got 1
      
      $var2 = 'BBB';
      $got = $var2 =~ tr/A/1/s; # works as $got = $var2 =~ s{[\x00-\xFF]*}{mb::tr($&,q/A/,q/1/,'sr')}e;
        BAD ==> got 1
      
      $var3 = 'AAA';
      $got = mb::tr($var3,'A','1','s'); # works as $got = mb::tr($var3,'A','1','s');
        GOOD ==> got 3
      
      Transliteration routine
      
      $return = mb::tr($MBCS_string, $searchlist, $replacementlist, $modifier);
      $return = mb::tr($MBCS_string, $searchlist, $replacementlist);
      
      This subroutine is a runtime routine to implement tr/// operator for MBCS
      codepoint. This subroutine scans an $MBCS_string by codepoint and replaces all
      occurrences of the codepoint found in $searchlist with the corresponding
      codepoint in $replacementlist. It returns the number of codepoint replaced or
      deleted except on /s modifier used.
      
      $modifier are:
      
      ---------------------------------------------------------------------------
      Modifier   Meaning
      ---------------------------------------------------------------------------
      c          Complement $searchlist.
      d          Delete found but unreplaced characters.
      s          Squash duplicate replaced characters.
      r          Return transliteration and leave the original string untouched.
      ---------------------------------------------------------------------------
      
      To use with a read-only value without raising an exception, use the /r modifier.
      
      print mb::tr('bookkeeper','boep','peob','r'); # prints 'peekkoobor'
  • mb::substr as Lvalue

    If perl version is older than 5.14, mb::substr differs from CORE::substr, and cannot be used as an lvalue. To change part of a string, you need use the optional fourth argument which is the replacement string.

    mb::substr($string, 13, 4, "JPerl");

    If you use perl 5.14 or later, you can use lvalue feature.

Not Supported Features

mb.pm modulino does not support the following features. In our experience with JPerl, these features are rarely needed. Moreover, if we are going to implement these, we will need a large amount of code, and we will need to update it frequently. If we are going to implement these, it's better to implement them as other modules.

  • Delimiter of String and Regexp

    qq//, q//, qw//, qx//, qr//, m//, s///, tr///, and y/// can't use a wide codepoint as the delimiter. I didn't implement this feature because it's rarely needed.

  • fc(), lc(), lcfirst(), uc(), and ucfirst()

    fc() not supported. lc(), lcfirst(), uc(), and ucfirst() support US-ASCII only.

      # suggested module name
      use mb::Casing; # supports for all MBCS, including UTF-8
      my $lc_string      = mb::Casing::lc($string);
      my $lcfirst_string = mb::Casing::lcfirst($string);
      my $uc_string      = mb::Casing::uc($string);
      my $ucfirst_string = mb::Casing::ucfirst($string);
      my $fc_string      = mb::Casing::fc($string);
  • Cloister of Regular Expression

    The cloister (?i) and (?i:...) of a regular expression on encoding of big5, big5hkscs, gb18030, gbk, sjis, and uhc will not be implemented for the time being. I didn't implement this feature because it was difficult to implement and less necessary. If you're interested in this issue, try challenge it.

  • Named Codepoint

    A named codepoint, such \N{GREEK SMALL LETTER EPSILON}, \N{greek:epsilon}, or \N{epsilon} is not supported.

      # suggested module name
      use mb::Charnames qw( %N ); # supports for all MBCS, including UTF-8
      print "$N{'GREEK SMALL LETTER EPSILON'}";
      
      # By the way, you know how great it is to be able to write MBCS literal strings in your Perl scripts, right?
  • Unicode Properties (aka Codepoint Properties) of Regular Expression

    Unicode properties (aka codepoint properties) of regexp are not available. Also (?[]) in regexp of perl 5.18 is not available. There is no plans to currently support these.

      # suggested module name
      use mb::RegExp::Properties qw( %p %P ); # supports for all MBCS, including UTF-8
      $string =~ /$p{Uppercase}/;

    This feature (\p{prop} and \P{prop}) is not stable in the Perl specification. Thus, this feature is not available in scripts that require long-term maintenance.

      For example, [:alpha:]
      at Perl 5.005   (not supported)
      at Perl 5.6     \p{IsAlpha}
      at Perl 5.12.1  \p{PosixAlpha}, and \p{Alpha}
      at Perl 5.14    \p{X_POSIX_Alpha}, \p{POSIX_Alpha}, \p{XPosixAlpha}, and \p{PosixAlpha}
  • \b{...} \B{...} Boundaries in Regular Expressions

    Following \b{...} \B{...} available starting in Perl 5.22 are not supported.

      \b{gcb} or \b{g}   Unicode "Grapheme Cluster Boundary"
      \b{sb}             Unicode "Sentence Boundary"
      \b{wb}             Unicode "Word Boundary"
      \B{gcb} or \B{g}   Unicode "Grapheme Cluster Boundary" doesn't match
      \B{sb}             Unicode "Sentence Boundary" doesn't match
      \B{wb}             Unicode "Word Boundary" doesn't match
    
      # suggested module name
      use mb::RegExp::Boundaries qw( %b %B ); # supports for all MBCS, including UTF-8
      $string =~ /$b{wb}(.+)$b{wb}/;

    This feature (\b{...} and \B{...}) considered not yet stable in the Perl specification.

  • Modifier /a /d /l and /u of Regular Expression

    I have removed these modifiers to remove your headache. The concept of this software is not to use two or more encoding methods as literal string and literal of regexp in one Perl script. Therefore, modifier /a, /d, /l, and /u are not supported. \d means [0-9] universally.

  • ?? and m?? are Not Supported

    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 '?'. Here's a quote words from Dan Kogai-san. "I'm just a programmer, so I can't fix the bug of the spec."

  • format

    Unlike JPerl, mb.pm modulino does not support the format feature. Because it is difficult to implement and you can write the same script in other any ways.

Other Limitations

The following is a description of the minor incompatibilities. These are not likely to be programming constraints.

  • Limitation of Regular Expression

    This software has limitation from \G in multibyte anchoring. Only perl 5.30.0 or later can treat the codepoint string which exceeds 65534 octets with a regular expression, and only perl 5.10.1 or later can 32766 octets.

      see also,
      
      The upper limit "n" specifiable in a regular expression quantifier of the form "{m,n}" has been doubled to 65534

      In 5.10.0, the * quantifier in patterns was sometimes treated as {0,32767}

      perlre length limit
      http://stackoverflow.com/questions/4592467/perlre-length-limit

    Everything in this world has limits. If you use perl 5.10 or later, or perl 5.30 or later, you can increase those limits. That's all.

UTF8 Flag Considered Harmful, and Our Goals

Larry Wall must think that "escaping" is the best solution in this case.

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.

-- we have been taught so for a long time.

Perl is a powerful language for everyone, but UTF8 flag is a barrier for common beginners. Because everyone can only one task on one time. So calling Encode::encode() and Encode::decode() in application program is not better way. Making two scripts for information processing and encoding conversion may be better. Please trust me.

  In UNIX Everything is a File
  - In UNIX everything is a stream of bytes
  - In UNIX the filesystem is used as a universal name space

  - native encoding of file contents
  - native encoding of file name on filesystem
  - native encoding of command line
  - native encoding of environment variable
  - native encoding of API
  - native encoding of network packet
  - native encoding of database

Ideally, We'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.

    This software attempts to achieve this goal by embedded functions work as traditional and stably.

  • Goal #2:

    Old byte-oriented programs should magically start working on the new character-oriented data when appropriate.

    This software is not a magician, so cannot see your mind and run it.

    You must decide and write octet semantics or codepoint semantics yourself in case by case.

                                          JPerl,mb        utf8
          +--------------+-------+-------+-------+-------+-------+
          | data         |  Old  |  Old  |  New  |  Old  |  New  |
          +--------------+-------+-------+-------+-------+-------+
          | script       |  Old  |      Old      |      New      |
          +--------------+-------+---------------+---------------+
          | interpreter  |  Old  |              New              |
          +--------------+-------+-------------------------------+
          Old --- Old byte-oriented
          New --- New codepoint-oriented

    The reason why JPerl is very excellent is that it is at the position of (c). That is, it is almost not necessary to write a special code to process new codepoint oriented script.

  • 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 codepoint 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.

    mb.pm modulino keeps one "language" and one "interpreter."

  • Goal #5:

    mb.pm users will be able to maintain mb.pm by Perl.

    May the mb.pm 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 provides programming environment like at that time.

Perl's Motto

   Some computer scientists (the reductionists, in particular) would
  like to deny it, but people have funny-shaped minds. Mental geography
  is not linear, and cannot be mapped onto a flat surface without
  severe distortion. But for the last score years or so, computer
  reductionists have been first bowing down at the Temple of Orthogonality,
  then rising up to preach their ideas of ascetic rectitude to any who
  would listen.
 
   Their fervent but misguided desire was simply to squash your mind to
  fit their mindset, to smush your patterns of thought into some sort of
  Hyperdimensional Flatland. It's a joyless existence, being smushed.
  --- Learning Perl on Win32 Systems
 
  If you think this is a big headache, you're right. No one likes
  this situation, but Perl does the best it can with the input and
  encodings it has to deal with. If only we could reset history and
  not make so many mistakes next time.
  --- Learning Perl 6th Edition
 
   The most important thing for most people to know about handling
  Unicode data in Perl, however, is that if you don't ever use any Uni-
  code data -- if none of your files are marked as UTF-8 and you don't
  use UTF-8 locales -- then you can happily pretend that you're back in
  Perl 5.005_03 land; the Unicode features will in no way interfere with
  your code unless you're explicitly using them. Sometimes the twin
  goals of embracing Unicode but not disturbing old-style byte-oriented
  scripts has led to compromise and confusion, but it's the Perl way to
  silently do the right thing, which is what Perl ends up doing.
  --- Advanced Perl Programming, 2nd Edition
 
   However, the ability to have any character in a string means you can
  create, scan, and manipulate raw binary data as string -- something with
  which many other utilities would have great difficulty.

Combinations of mb.pm Modulino and Other Modules

  The following is a description of all the situations in mb.pm modulino is used in Japan.
