NAME

CP932NEC::R2 - provides minimal CP932NEC I/O subroutines by short name

SYNOPSIS

use CP932NEC::R2;

  @result = mbeach($utf8str)
  $result = mbtr($utf8str, 'ABC', 'XYZ', 'cdsr')
  $result = iolen($utf8str)
  $result = iomid($utf8expr, $offset_as_cp932nec, $length_as_cp932nec, $utf8replacement)
  @result = ioget(FILEHANDLE)
  $result = ioput(FILEHANDLE, @utf8str)
  $result = ioputf(FILEHANDLE, $utf8format, @utf8list)
  @result = iosort(@utf8str)

  $result = $utf8str =~ $mb{qr/$utf8regex/imsxo}
  $result = $utf8str =~ m<$mb{qr/$utf8regex/imsxo}>gc
  $result = $utf8str =~ s<$mb{qr/before/imsxo}><after>egr

MBCS SUBROUTINES for SCRIPTING

It is useful to treat regex in perl script as code point of UTF-8. Following subroutines and tied hash variable provide UTF-8 semantics for us.

MBCS SUBROUTINES for I/O

If you use following subroutines then I/O encoding convert is automatically. These subroutines provide CP932NEC octets semantics for you.

------------------------------------------------------------------------------------------------------------------------------------------

Octet in Script          Octet of I/O Encoding                       Note and Limitations
------------------------------------------------------------------------------------------------------------------------------------------
<FILEHANDLE>             ioget(FILEHANDLE)                           get UTF-8 codepoint octets from CP932NEC file
------------------------------------------------------------------------------------------------------------------------------------------
length                   iolen($utf8str)                             octet count of UTF-8 string as CP932NEC encoding
------------------------------------------------------------------------------------------------------------------------------------------
print                    ioput(FILEHANDLE, @utf8str)                 print @utf8str as CP932NEC encoding
------------------------------------------------------------------------------------------------------------------------------------------
printf                   ioputf(FILEHANDLE, $utf8format, @utf8list)  printf @utf8str as CP932NEC encoding
------------------------------------------------------------------------------------------------------------------------------------------
sort                     iosort(@utf8str)                            sort @utf8str as CP932NEC encoding

sprintf                  (nothing)                                   "iosputf" is bad interface because it makes confuse by bringing
                                                                     both internal code and external code into your script
------------------------------------------------------------------------------------------------------------------------------------------
substr                   iomid($utf8expr, $offset_as_cp932nec, $length_as_cp932nec, $utf8replacement)
                                                                     substr $utf8expr as CP932NEC octets
