NAME

Windows1252 - Source code filter to escape Windows-1252 script

Install and Usage

There are two steps there:

You'll have to download Windows1252.pm and Ewindows1252.pm and put it in your perl lib directory.
You'll need to write "use Windows1252;" at head of the script.

SYNOPSIS

use Windows1252;
use Windows1252 ver.sion;             --- require minimum version
use Windows1252 ver.sion.0;           --- expects version (match or die)

# "no Windows1252;" not supported

or

$ perl Windows1252.pm Windows-1252_script.pl > Escaped_script.pl.e

then

$ perl Escaped_script.pl.e

Windows-1252_script.pl  --- script written in Windows-1252
Escaped_script.pl.e --- escaped script


dummy functions:
  utf8::upgrade(...);
  utf8::downgrade(...);
  utf8::encode(...);
  utf8::decode(...);
  utf8::is_utf8(...);
  utf8::valid(...);
  bytes::chr(...);
  bytes::index(...);
  bytes::length(...);
  bytes::ord(...);
  bytes::rindex(...);
  bytes::substr(...);

ABSTRACT

Windows1252 software is "middleware" between perl interpreter and your Perl script written in Windows-1252.

Perl is optimized for problems which are about 90% working with text and about 10% everything else. Even if this "text" doesn't contain Windows-1252, Perl3 or later can treat Windows-1252 as binary data.

By "use Windows1252;", it automatically interpret your script as Windows-1252. The various functions of perl including a regular expression can treat Windows-1252 now. The function length treats length per byte. This software does not use UTF8 flag.

Yet Another Future Of

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 is an implementation of Perl written in Java.

jPerl - Perl on the JVM

jperl (Jonathan Perl)

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 Windows-1252 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
Remains One Language Handling Raw Windows-1252, Doesn't Use UTF8 flag like JPerl
Remains One Interpreter like Encode module
Code Set Independent like Ruby
Monolithic Script like cpanminus
There's more than one way to do it like Perl itself

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

JRE: JPerl Runtime Environment

+---------------------------------------+
|        JPerl Application Script       | Your Script
+---------------------------------------+
|  Source Code Filter, Runtime Routine  | ex. Windows1252.pm, Ewindows1252.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.

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.

Command-line Wildcard Expansion on DOS-like Systems

The default command shells on DOS-like systems (COMMAND.COM or cmd.exe or Win95Cmd.exe) do not expand wildcard arguments supplied to programs. Instead, import of Ewindows1252.pm works well.

in Ewindows1252.pm
#
# @ARGV wildcard globbing
#
sub import {

    if ($^O =~ /\A (?: MSWin32 | NetWare | symbian | dos ) \z/oxms) {
        my @argv = ();
        for (@ARGV) {

            # has space
            if (/\A (?:$q_char)*? [ ] /oxms) {
                if (my @glob = Ewindows1252::glob(qq{"$_"})) {
                    push @argv, @glob;
                }
                else {
                    push @argv, $_;
                }
            }

            # has wildcard metachar
            elsif (/\A (?:$q_char)*? [*?] /oxms) {
                if (my @glob = Ewindows1252::glob($_)) {
                    push @argv, @glob;
                }
                else {
                    push @argv, $_;
                }
            }

            # no wildcard globbing
            else {
                push @argv, $_;
            }
        }
        @ARGV = @argv;
    }
}

Software Composition

Windows1252.pm               --- source code filter to escape Windows-1252
Ewindows1252.pm              --- run-time routines for Windows1252.pm

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. It means incompatible upgrade of Perl should be rewound.

Escaping Your Script (You do)

You need write 'use Windows1252;' in your script.

Un-Escaping \ of \N, \p, \P, and \X (Windows1252.pm provides)

Windows1252.pm removes '\' at head of alphanumeric regexp metasymbols \N, \p, \P and \X. By this method, you can avoid the trap of the abstraction.

See also, Deprecate literal unescaped "{" in regexes. http://perl5.git.perl.org/perl.git/commit/2a53d3314d380af5ab5283758219417c6dfa36e9

Escaping Built-in Functions (Windows1252.pm and Ewindows1252.pm provide)

Insert 'Ewindows1252::' at head of function name. Ewindows1252.pm provides your script Ewindows1252::* subroutines.

Un-Escaping bytes::* Subroutines (Windows1252.pm provides)

Windows1252.pm removes 'bytes::' at head of subroutine 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 Standard Module Content (You do)

You need copy built-in standard module to /Perl/site/lib/Windows1252 and change 'use utf8;' to 'use Windows1252;' in its. You need help yourself for now.

Back to and see 'Escaping Your Script'. Enjoy hacking!!

Comment out pragma to ignore utf8 environment, and Ewindows1252.pm provides these
functions.

Dummy utf8::upgrade

$num_octets = utf8::upgrade($string);

Returns the number of octets necessary to represent the string.

Dummy utf8::downgrade

$success = utf8::downgrade($string[, FAIL_OK]);

Returns true always.

Dummy utf8::encode

utf8::encode($string);

Returns nothing.

Dummy utf8::decode

$success = utf8::decode($string);

Returns true always.

Dummy utf8::is_utf8

$flag = utf8::is_utf8(STRING);

Returns false always.

Dummy utf8::valid

$flag = utf8::valid(STRING);

Returns true always.

Dummy bytes::chr
```
This subroutine is same as chr.
```
Dummy bytes::index
```
This subroutine is same as index.
```
Dummy bytes::length
```
This subroutine is same as length.
```
Dummy bytes::ord
```
This subroutine is same as ord.
```
Dummy bytes::rindex
```
This subroutine is same as rindex.
```
Dummy bytes::substr
```
This subroutine is same as substr.
```

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)

BUGS, LIMITATIONS, and COMPATIBILITY

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 Windows1252 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.

cloister of regular expression

The cloister (?s) and (?i) of a regular expression will not be implemented for the time being. Cloister (?s) can be substituted with the .(dot) and \N on /s modifier. Cloister (?i) can be substituted with \F...\E.
Modifier /a /d /l and /u of Regular Expression

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.
Named Character

A named character, such \N{GREEK SMALL LETTER EPSILON}, \N{greek:epsilon}, or \N{epsilon} is not supported.
Unicode Properties (aka Character Properties) of Regular Expression

Unicode properties (aka character properties) of regexp are not available. Also (?[]) in regexp of Perl 5.18 is not available. There is no plans to currently support these.
eval "string"

The function which escapes "string" of eval has not been implemented yet. It will be supported in future versions.
Delimiter of String and Regexp

qq//, q//, qw//, qx//, qr//, m//, s///, tr///, and y/// can't use a wide character as the delimiter.

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 this method, let's drag out page 402 of the old dusty Programming Perl, 3rd ed. again.

Information processing model beginning with perl3 or this software of
UNIX/C-ism.

  +--------------------------------------------+
  |       Text strings as Binary strings       |
  |       Binary strings as Text strings       |
  +--------------------------------------------+
  |        Not UTF8 Flagged, UNIX/C-ism        |
  +--------------------------------------------+

Script could be written in native encoding of operating systems.
- Like contents of a file
- Like a file name on the file systems
- Like command lines
- Like environment variables
- Like parameters of API

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

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.

This goal has been achieved by that this software is additional code for perl like utf8 pragma. Perl should work same as past Perl if added nothing.

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 built-in 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,japerl    Encode,Windows1252
+--------------+-------+-------+-------+-------+-------+
| 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.

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.

Someday, I want to ask Larry Wall about this goal in the elevator.
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.

Windows1252 software remains one language and one interpreter.
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.

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.
