=head1 NAME
Latin7 - Source code filter to escape Latin-7 script
=head1 Install and Usage
There are two steps there:
=over 2
=item * You'll have to download Latin7.pm and Elatin7.pm and put it in your perl lib directory.
=item * You'll need to write "use Latin7;" at head of the script.
=back
=head1 SYNOPSIS
use Latin7;
use Latin7 ver.sion; --- require minimum version
use Latin7 ver.sion.0; --- expects version (match or die)
# "no Latin7;" not supported
or
$ perl Latin7.pm Latin-7_script.pl > Escaped_script.pl.e
then
$ perl Escaped_script.pl.e
Latin-7_script.pl --- script written in Latin-7
Escaped_script.pl.e --- escaped script
subroutines:
Latin7::eval(...);
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(...);
=head1 ABSTRACT
Latin7 software is "middleware" between perl interpreter and your Perl script
written in Latin-7.
Perl is optimized for problems which are about 90% working with text and about
10% everything else. Even if this "text" doesn't contain Latin-7, Perl3 or later
can treat Latin-7 as binary data.
By "use Latin7;", it automatically interpret your script as Latin-7. The various
functions of perl including a regular expression can treat Latin-7 now.
The function length treats length per byte. This software does not use UTF8
flag.
=head1 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.
http://www.javainc.com/projects/jperl/
jPerl - Perl on the JVM
http://www.dzone.com/links/175948.html
Jamie's PERL scripts for bioinformatics
http://code.google.com/p/jperl/
jperl (Jonathan Perl)
https://github.com/jperl
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 Latin-7
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.
=over 2
=item * Upper Compatibility like Perl4 to Perl5
=item * Maximum Portability like jcode.pl
=item * Remains One Language Handling Raw Latin-7, Doesn't Use UTF8 flag like JPerl
=item * Remains One Interpreter like Encode module
=item * Code Set Independent like Ruby
=item * Monolithic Script like cpanminus
=item * There's more than one way to do it like Perl itself
=back
I am excited about this software and Perl's future --- I hope you are too.
=head1 JRE: JPerl Runtime Environment
+---------------------------------------+
| JPerl Application Script | Your Script
+---------------------------------------+
| Source Code Filter, Runtime Routine | ex. Latin7.pm, Elatin7.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;
}
$status;
}
sub import {
filter_add(\&multibyte_filter);
}
1;
I am glad that I could confirm my idea is not so wrong.
=head1 Command-line Wildcard Expansion on DOS-like Systems
The default command shells on DOS-like systems (COMMAND.COM or cmd.exe or
Win95Cmd.exe) do not expand wildcard arguments supplied to programs. Instead,
import of Elatin7.pm works well.
in Elatin7.pm
#
# @ARGV wildcard globbing
#
sub import {
if ($^O =~ /\A (?: MSWin32 | NetWare | symbian | dos ) \z/oxms) {
my @argv = ();
for (@ARGV) {
# has space
if (/\A (?:$q_char)*? [ ] /oxms) {
if (my @glob = Elatin7::glob(qq{"$_"})) {
push @argv, @glob;
}
else {
push @argv, $_;
}
}
# has wildcard metachar
elsif (/\A (?:$q_char)*? [*?] /oxms) {
if (my @glob = Elatin7::glob($_)) {
push @argv, @glob;
}
else {
push @argv, $_;
}
}
# no wildcard globbing
else {
push @argv, $_;
}
}
@ARGV = @argv;
}
}
=head1 Software Composition
Latin7.pm --- source code filter to escape Latin-7
Elatin7.pm --- run-time routines for Latin7.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.
It means incompatible upgrade of Perl should be rewound.

=head1 Un-Escaping \ of \b{}, \B{}, \N{}, \p{}, \P{}, and \X (Latin7 software provides)
Latin7 software removes '\' at head of alphanumeric regexp metasymbols \b{}, \B{},
\N{}, \p{}, \P{} and \X. By this method, you can avoid the trap of the abstraction.

=head1 Yada Yada Operator (Latin7 software provides)
The yada yada operator (noted ...) is a placeholder for code. Perl parses it
without error, but when you try to execute a yada yada, it throws an exception
with the text Unimplemented:
sub unimplemented { ... }
eval { unimplemented() };
if ( $@ eq 'Unimplemented' ) {
print "I found the yada yada!\n";
}
You can only use the yada yada to stand in for a complete statement. These
examples of the yada yada work:
{ ... }
sub foo { ... }
...;
eval { ... };
sub foo {
my( $self ) = shift;
...;
}
do { my $n; ...; print 'Hurrah!' };
The yada yada cannot stand in for an expression that is part of a larger statement
since the ... is also the three-dot version of the range operator
(see "Range Operators"). These examples of the yada yada are still syntax errors:
print ...;
open my($fh), '>', '/dev/passwd' or ...;
if ( $condition && ... ) { print "Hello\n" };
There are some cases where Perl can't immediately tell the difference between an
expression and a statement. For instance, the syntax for a block and an anonymous
hash reference constructor look the same unless there's something in the braces that
give Perl a hint. The yada yada is a syntax error if Perl doesn't guess that the
{ ... } is a block. In that case, it doesn't think the ... is the yada yada because
it's expecting an expression instead of a statement:
my @transformed = map { ... } @input; # syntax error
You can use a ; inside your block to denote that the { ... } is a block and not a
hash reference constructor. Now the yada yada works:
my @transformed = map {; ... } @input; # ; disambiguates
my @transformed = map { ...; } @input; # ; disambiguates
=head1 Un-Escaping bytes::* Subroutines (Latin7 software provides)

=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
CHAR_NONBLOCK.
Example:
SET CHAR_NONBLOCK=1
(The value '1' doesn't have the meaning)
=head1 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 Latin7 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.
=over 2
=item * 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.
=item * 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.
=item * Named Character
A named character, such \N{GREEK SMALL LETTER EPSILON}, \N{greek:epsilon}, or
\N{epsilon} is not supported.
=item * 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.
=item * Delimiter of String and Regexp
qq//, q//, qw//, qx//, qr//, m//, s///, tr///, and y/// can't use a wide character
as the delimiter.
=item * \b{...} Boundaries in Regular Expressions
Following \b{...} available starting in v5.22 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

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.
/* You are not expected to understand this */

+--------------------------------------------+
http://perl-users.jp/articles/advent-calendar/2010/casual/4
Confusion of Perl string model is made from double meanings of
"Binary string."
Meanings of "Binary string"
1. Non-Text string
2. Digital octet string
Let's draw again using those term.
+----------------------+---------------------+

+--------------------------------------------+
There are people who don't agree to change in the character string
processing model of Perl 5.8. It is impossible to get to agree it to
majority of Perl user who hardly ever use Perl.
How to solve it by returning to a original 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.

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 Scripting
- 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, 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.
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.
=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 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,Latin7
+--------------+-------+-------+-------+-------+-------+
| 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.
(May the japerl take over JPerl!)
=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.
Someday, I want to ask Larry Wall about this goal in the elevator.
=item * 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.
Latin7 software remains one language and one interpreter.
=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 provides
programming environment like at that time.
=head1 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.
