ShiftJIS::Regexp Description

ShiftJIS::Regexp contains regular expressions in Shift-JIS. ShiftJIS::Regexp contains regular expressions in Shift-JIS.SYNOPSIS use ShiftJIS::Regexp qw(:all); match($string, 'p{Hiragana}{2}p{Digit}{2}'); match($string, 'pH{2}pD{2}'); # these two are equivalent:This module provides some functions to use regular expressions in Shift-JIS on the byte-oriented perl.The legal Shift-JIS character in this module must match the following regular expression: |To avoid false matching in multibyte encoding, this module uses anchoring technique to ensure each matching position places at the character boundaries.cf. perlfaq6, "How can I match strings with multibyte characters?"Functionsre(PATTERN) re(PATTERN, MODIFIER)Returns a regular expression parsable by the byte-oriented perl.PATTERN is specified as a string. MODIFIER is specified as a string. Modifiers in the following list are allowed. i case-insensitive pattern (only for ascii alphabets) I case-insensitive pattern (greek, cyrillic, fullwidth latin) j hiragana-katakana-insensitive pattern (but halfwidth katakana are not considered.) s treat string as single line m treat string as multiple lines x ignore whitespace (i.e. ) unless backslashed or inside a character class; but comments are not recognized! o once parsed (not compiled!) and the result is cached internally.o modifier while () { print replace($_, '(perl)', '$1', 'igo'); } is more efficient than while () { print replace($_, '(perl)', '$1', 'ig'); } because in the latter case the pattern is parsed every time whenever the function is called.match(STRING, PATTERN) match(STRING, PATTERN, MODIFIER)An emulation of m// operator aware of Shift-JIS. But, to emulate @list = $string =~ m/PATTERN/g, the pattern should be parenthesized (capturing parentheses are not added automatically). @list = match($string, 'pH', 'g'); # wrong; returns garbage! @list = match($string,'(pH)','g'); # goodPATTERN is specified as a string. MODIFIER is specified as a string. i,I,j,s,m,x,o please see re(). g match globally z tell the function the pattern matches an empty string (sorry, due to the poor auto-detection)replace(STRING or SCALAR REF, PATTERN, REPLACEMENT) replace(STRING or SCALAR REF, PATTERN, REPLACEMENT, MODIFIER)An emulation of s/// operator but aware of Shift-JIS.If a reference to a scalar is specified as the first argument, substitutes the referent scalar and returns the number of substitutions made. If a string (not a reference) is specified as the first argument, returns the substituted string and the specified string is unaffected.MODIFIER is specified as a string. i,I,j,s,m,x,o please see re(). g,z please see match().jsplit(PATTERN or ARRAY REF of , STRING) jsplit(PATTERN or ARRAY REF of , STRING, LIMIT)An emulation of CORE::split but aware of Shift-JIS.In scalar/void context, it does not split into the @_ array; in scalar context, only returns the number of fields found.PATTERN is specified as a string. But ' ' as PATTERN has no special meaning; it splits the string on a single space similarly to CORE::split / /.When you want to split the string on whitespace, pass an undefined value as PATTERN or use the splitspace() function. jsplit(undef, " x81x40 This is x81x40 perl."); splitspace(" x81x40 This is x81x40 perl."); # ('This', 'is', 'perl.')If you want to pass pattern with modifiers, specify an arrayref of as the first argument. You can also use "Embedded Modifiers").MODIFIER is specified as a string. i,I,j,s,m,x,o please see re().splitspace(STRING) splitspace(STRING, LIMIT)This function emulates CORE::split(' ', STRING, LIMIT). It returns a list given by split STRING on whitespace including "x81x40" (IDEOGRAPHIC SPACE). Leading whitespace characters do not produce any field.Note: splitspace(STRING, LIMIT) is equivalent to jsplit(undef, STRING, LIMIT).splitchar(STRING) splitchar(STRING, LIMIT)This function emulates CORE::split(//, STRING, LIMIT). It returns a list given by split of STRING into characters.Note: splitchar(STRING, LIMIT) is equivalent to jsplit('', STRING, LIMIT).Requirements:· Perl
