DESCRIPTION

       Multilingual file viewer
              lv  is  a powerful multilingual file viewer.  Apparently, lv looks like less (1), a
              representative file viewer on UNIX as you know, so UNIX people (and less people  on
              other OSs) don't have to learn a burdensome new interface.  lv can be used on MSDOS
              ANSI terminals and almost all UNIX platforms.  lv is a currently growing  software,
              so your feedback is welcome and helpful for us to refine the future lv.

       Multiple coding systems
              lv  can  decode  and  encode  multilingual streams through many coding systems, for
              example, ISO 2022 based coding systems such as iso-2022-jp, and EUC (Extended  Unix
              Code)  like  euc-japan.   Furthermore,  localized coding systems such as shift-jis,
              big5 and HZ are also supported.  lv can be used not only as a file viewer but  also
              as a coding-system translation filter like nkf (1) and tcs (1).

       Multilingual regular expressions / Multilingual grep
              lv  can recognize multi-bytes patterns as regular expressions, and lv also provides
              multilingual grep (1) functionality by giving  it  another  name,  lgrep.   Pattern
              matching is conducted in the charset level, so an EUC fragment, for example, can be
              found in the ISO 2022 tailored streams, of course.

       Supporting the Unicode standard
              lv provides Unicode facilities which enables you to handle Unicode streams  encoded
              in  UTF-7  or  UTF-8, and lv can also convert their code-points between Unicode and
              other charsets.  So you can display Unicode or  foreign  texts  on  your  terminal,
              using  the  code  conversion  function  to  your  favorite  charsets  via  Unicode.
              (However, MSDOS version of lv has none of the Unicode facility.)

       ANSI escape sequence through
              lv can recognize ANSI escape sequences for text decoration.  So you can look  ANSI-
              decorated  streams  such as colored source codes generated by another software just
              like intended image on ANSI terminals.

       Completely original
              lv is a completely original software including no code drawn from less and grep and
              other programs at all.

OPTIONS

       -A<coding-system>
              Set all coding systems to coding-system.

       -I<coding-system>
              Set input coding system to coding-system.

       -K<coding-system>
              Set  keyboard  coding  system  to  coding-system.   If it is not set, output coding
              system will be applied to it.

       -O<coding-system>
              Set output coding system to coding-system.

       -P<coding-system>
              Set pathname coding system to coding-system.

       -D<coding-system>
              Set default (fall-back) coding system to coding-system.

       coding-system:
              a: auto-select
              c: iso-2022-cn
              j: iso-2022-jp
              k: iso-2022-kr
              ec: euc-china
              ej: euc-japan
              ek: euc-korea
              et: euc-taiwan
              u7: UTF-7
              u8: UTF-8
              l1..9: iso-8859-1..9
              l0: iso-8859-10
              lb,ld,le,lf,lg: iso-8859-11,13,14,15,16
              s: shift-jis
              b: big5
              h: HZ
              r: raw mode

       Examples:
              -Il2: input coding system is iso-8859-2
              -Ks:  keyboard coding system is shift-jis
              -Oek: output coding system is euc-korea
              -Ab:  all coding systems are big5

       Coding-system translations / Code-points conversions:
              iso-2022-cn, -jp, -kr can be converted into euc-china or -taiwan,  euc-japan,  euc-
              korea, respectively (and vice versa).  shift-jis uses the same internal code-points
              as iso-2022-jp and euc-japan.

              Since big5  characters  can  be  converted  into  CNS  11643-1992  with  negligible
              incompleteness,  big5 streams can be translated into iso-2022-cn or euc-taiwan (and
              vice versa) with code-points conversion.  Note that the iso-2022-cn  referred  here
              is  not  GB  sequence,  only  just  CNS  one.   You  should remember that lv cannot
              translate big5 into GB directly.

              The search function of lv may not work  correctly  when  lv  additionally  performs
              ``code-points''  conversion  (not  ``coding-system''  translation), because visible
              code and internal code are different from each other.  lv will try  to  avoid  this
              problem  with  converting  charsets  of  search  patterns  automatically,  but this
              function is not always perfect.

       -W<number>
              Screen width

       -H<number>
              Screen height

       -E'<editor>' (default 'vi -c %d')
              Editor name (default 'vi -c %d')
              ``%d'' means the line number of current position in a file.

       -q     Assert there is delete/insert-lines control.
              Please set this option on a MSDOS ANSI  terminal  that  has  capability  to  delete
              and/or  insert  lines.   As  to  termcap  and  terminfo  version,  it  will  be set
              automatically.

       -Ss<seq>
              Set ANSI Standout sequence to seq  (default "7")

       -Sr<seq>
              Set ANSI Reverse sequence to seq   (default "7")

       -Sb<seq>
              Set ANSI Blink sequence to seq     (default "5")

       -Su<seq>
              Set ANSI Underline sequence to seq (default "4")

       -Sh<seq>
              Set ANSI Highlight sequence to seq (default "1")

              These sequences are inserted between ``ESC ['' and ``m''  to  construct  full  ANSI
              escape sequences.

       -T<number>
              Set  Threshold-code  which  divides  Unicode code-points in two regions. Characters
              belonging to the lower region are assumed to have a width of one,  and  the  higher
              characters are equated to a width of two. (Default: 12288, = 0x3000)

       -m     Force  Unicode code-points which have the same glyphs as iso-8859-* to be Mapped to
              iso-8859-* in a conversion from Unicode to another character set which also has the
              corresponding code-points, in particular, Asian charsets.

       -a     Adjust character set for search pattern (default)

       -c     Allow ANSI escape sequences for text decoration (Color)

       -d, -i Make regexp-searches ignore case (case folD search) (default)

       -f     Substitute Fixed strings for regular expressions

       -k     Convert X0201 Katakana to X0208 while decoding

       -l     Allow  physical lines of each logical line printed on the screen to be concatenated
              for cut and paste after screen refresh

       -s     Force old pages to be swept out from the screen Smoothly

       -u     Unify several character sets, eg. JIS X0208 and C6226.  In addition, lv equates ISO
              646 variants, eg. JIS X0201-Roman, and unknown charsets with ASCII.

       -g     Turn on lgrep mode.

       -n     Prefix each line of output with the line number within its input file on lgrep.

       -v     Invert the sense of matching on lgrep.

       -z     Enable HZ auto-detection (also enabled by run-time C-t).

       -+     Clear all options
              You can also turn OFF specified options, using ``+<option>'' like +c, +d, ... +z.

       -      Treat the following arguments as filenames

       grep-pattern
              lv works like grep (1) when its name is lgrep

       +number
              Jump to the specified line immediately when lv is invoked.

       +/grep-pattern
              Search  the specified pattern immediately when lv is invoked.

       -V     Show lv version

       -h     Show this help

CONFIGURATION

       Options  can  be described in configuration file ``.lv'' (``_lv'' on MSDOS) located at you
       HOME directory.  If and only if you use MSDOS, you can locate ``_lv'' at  current  working
       directory.    They   can  be  also  described  in  the  environment  variable  LV.   Every
       configuration will be overloaded in this order if  there  is.  Command  line  options  are
       always read finally.
