Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12.

  • 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. +
+ +
+ + +

+Sample Images

+ + + + +
+ + +

+Download lv

+ + +
+You can download lv archive. +Changes between older versions are described in +release note +(in Japanese). +
+ + + +
+ + +

+Installation

+ + +
    + Standard installation: +

    +

      +
    1. Expand lv archive, using gunzip/tar. +
    2. Change your working directory to ``(extracted sub directory)/build''. +
    3. Execute ``../src/configure'' to configure compiler flags. +
    4. Launch ``make''. +
    5. Then, launch ``make install'' as root. +
    +

    + MSDOS installation: +

    + Before making lv, + you need to install + + LSI C-86 Compiler + + (limited and freeware version of LSI C-86 for sample usage). +

    +

      +
    1. Expand lv archive, using gunzip/tar. +
    2. Change your working directory to ``(extracted sub directory)/src''. +
    3. Launch ``make -f Makefile.dos''. +
    4. Copy ``lv.hlp'', brief help description, to the same directory + as lv.exe settled. +
    +

    + MSDOS version of lv directly outputs ANSI escape sequences + without regard to termcap and terminfo. + Perhaps you need an ANSI escape sequence driver named ``ANSI.SYS'' + (or more sophisticated one) on MSDOS + including DOS prompt on MS-Windoze. + Since Windoze-NT does not seem to prepare such drivers + for DOS prompt in default, + please look into the driver configuration + when lv fails to handle the terminal capability correctly. +

+ +
+ + +

+Usage

+ + +
    + +

  • How to launch lv?

    +     + When you just wish to display a file on a terminal, + please launch lv from command line like this: +

    +

    + % lv [options] files ...
    +
    +

    + Or, using redirect or pipe-line: +

    +

    + % another_command | lv [options]
    + % lv [options] < file +
    +

    + Compressed files that have suffix ``gz'', ``z'', or ``GZ'', ``Z'' are + extracted by lv using zcat (1), + and ``bz2'' or ``BZ2'' with bzcat (1). + Please install zcat and bzcat that can expand all of them. +

    + In case that standard output is not connected to an ordinal terminal + but to redirect or pipe-line, + lv works as a coding-system or code-points conversion filter + like nkf (1) and tcs (1). +

    + lv also works like grep (1) + by giving it another name, lgrep. + Please install symbolic (or hard) link + whose name is lgrep to lv (1). + Or, lgrep functionality is also turned on the option '-g'. + lgrep is used like below: +

    +

    + % lgrep [options] grep_pattern files ...
    + % another_command | lgrep [options] grep_pattern
    + % lgrep [options] grep_pattern < file +
    +

    + The coding-system of grep_pattern can be specified + as ``keyboard coding system'' (see below). +

    + +

  • Command line options

    +
    +

    +

    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. +

  • Configuration

    +     + Options can be described in the 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 the following order if there is. + Command line options are always read finally. +

    +

      +
    1. .lv located at your home directory +
    2. (_lv located at current working directory: MSDOS only) +
    3. Environment variable LV +
    4. Command line options +
    +

    + Examples: +

  • How to input search strings?

    +     + You can input a string which consists of multi-bytes characters + and search the string as a regular expression. + lv's regular expression is similar to Mule's one. +

    + The following keys have special meanings in the keyboard input: +

    +

    +
    C-m, Enter

  • Regular expressions

    +     +
      +
    • `. (period)'
      + matches any single character. + For example, + ``a.b'' matches any three-character string which begins with + `a' and ends with `b'. +
    • `*'
      + constructs repetition of an expression more than 0 times. + For example, + ``ab*'' matches `a', `ab' `abb', etc. +
    • `+'
      + constructs repetition of an expression more than once. + For example, + ``ab+'' matches `ab', `abb', but not `a'. +
    • `?'
      + matches the preceding expression either once or not at all. + For example, + ``ca?r'' matches `car' or `cr'; nothing else. +
    • `[ ... ]'
      + makes a character set. + For example, + ``[ab]+'' matches any string composed of just `a's and `b's. + You can also include character ranges in a character set, + by writing two characters with a `-' between them. + For example, + ``[a-z]'' matches any lower-case letter. + If the characters implies a multi-bytes charset, + lv makes a multi-bytes range, + ordering code-points as unsigned integer. + Mutually overlapping ranges (or charset) are not guaranteed. +
    • `[^ ... ]'
      + makes a complemented character set. + For example, + ``[^a-z0-9A-Z]'' matches all characters + *except* letters and digits. +
    • `^'
      + matches the empty string at the beginning of a line. +
    • `$'
      + is similar to `^' but matches only at the end of a line. +
    • `\'
      + quotes the special characters. +
    • `\1'
      + matches characters each of which has a width of 1 column. +
    • `\2'
      + matches characters each of which has a width of 2 columns. +
    • `\|'
      + specifies an alternative. + For example, + ``foo\|bar'' matches either `foo' or `bar' but no other string. +
    • `\( ... \)'
      + \(, \) is a grouping construct. + For example, + ``ba\(na\)*'' matches `ba', `bana', `banana', etc. +
    +
+ +
+ + +

+Limitations

+ + +
    +

  • Up to 8192 bytes per a logical line

    + lv manages file location pointers logically, + separating LOGICAL lines by LF (line feed) or CR (carriage return), + or CR/LF. + The length of a logical line is limited up to 8192 bytes. + And lv insert a LF forcibly when a line has a length over 8192 bytes. + Note that all of CRs or CR/LF are replaced with single LF on UNIX + during decoding. + As to MSDOS, + CRs are inserted before every LFs without thinking. +

    +

  • Physical lines per a logical line

    + A logical line is divided into PHYSICAL lines + to fall into the screen width. + lv limits physical lines up to "characters / 16" lines length + per a logical line for management of them. + Note that when a logical line has more lines, + the rest of the limit are truncated and not displayed at all. +

    +

  • Limitation of encoding space

    + Encoding space is limited upto "characters * 4" bytes length + for each decoded string. + Even if encoded string would be longer than that, + the encoding process is dropped at the limit. +

    +

  • Limitation of the number of logical lines

    + The number of logical lines is also limited. + Currently, + lv can handle up to about 2 Giga lines on UNIX + (65000 lines on MSDOS). + Note that lines which exceed this limitation cannot be displayed at all. +
+ +
+ + +

+Coding systems

+ +
    + +

  • ISO 2022 based coding systems

    +     + lv handles ISO 2022 based coding systems as + they are stateless on the logical line level. + So you have to specify a coding system before decoding, + and lv maybe adds redundant codes during encoding. +

    +

    + Currently lv's mapping table is based on Unicode 1.1. +

    + +

    + +

  • Other coding systems

    +     +
      + +
    • iso-8859-*
      +       + ASCII and one of ISO 8859/1-16 are designated on G0:G1 + invoked to GL:GR, respectively. +

      + +

    • shift-jis
      +       + lv can decode mixture texts of shift-jis and iso-2022-jp, + when you select shift-jis as the input coding system. +

      + Note that euc-japan and shift-jis are mutually exclusive for decoding. +

      + +

    • big5
      +       + Since big5 characters can be partially converted + into CNS 11643-1992 Plane 1-2, + lv can load big5 streams + and output them through ISO 2022 based coding systems or euc-taiwan. + Several big5 characters which have no correspondence to CNS + are output as ``?'' (question mark). +

      + +

    • HZ
      +       + HZ is defined in RFC 1843. + It would consist of four escape sequences, ~~, ~{, ~}, and ~\n, + but lv does not support the last one, ~\n sequence, + and leaves it alone. + You should remember that lv does not conform full of RFC 1843. + HZ will be decoded as euc-china in lv. +

      + +

    • raw mode
      +       + No decoding and encoding is performed. +

    + +

  • Handling of invalid codes

    +     + Characters belonging to invalid character sets, for example, + JIS X 0212 for shift-jis, + are printed as ASCII at its code-point + up to originally supposed width. +

    + Invalid characters which cause error state + under specified coding system + might be ignored partially. + If it is printable, + it will be output as a control character. +

    + +

  • Backspace

    +     + BS (backspace) characters included in files + are interpreted as follows: +

    +

      +
    • <char> BS <char>
      + Highlighted <char> +
    • ``_'' BS <char>
      + Underlined <char> +
    • ``o'' BS ``+''
      + Highlighted ``o'' +
    • Otherwise
      + BS deletes a character on the left side of it. +
    +

    + +

  • How to look in a binary file?

    +     + Decoding of lv is robust even for binary files. + You can look in a binary file and decode embedded strings in it. + However, + there might be ignored characters if you decode binary files + through a particular coding system. + Option -Ir, raw decoding, saves such ignored characters other than CRs. +
+ +
+ + +

+Auto selection of a coding system

+ +
    + +

  • Default coding system

    +     + Default input coding system is auto-select described below. + In auto selection state, + lv decodes an input stream as iso-2022-kr. + Default output coding system is iso-2022-jp on UNIX, + or shift-jis on MSDOS (as long as Japanese version of lv). +

    + If you don't specify any input coding system, + that is, when auto-select is specified, + lv will select input coding system automatically. +

    + +

  • How does lv select a coding system?

    +     + Auto selection state continues until an 8bit code is found, + and the auto selection of input coding system is performed on demand. +

    + When a 8bit code is found during file loading + and the input coding syste is auto-select (its entity is iso-2022-kr), + lv examines ``the first line that contains the first 8bit code''. + Then lv tries several 8bit decodings as below: +

    +

      +
    • simple euc decoding test (included euc-china and euc-korea) +
    • euc-japan (or euc-taiwan) decoding test +
    • big5 decoding test +
    • shift-jis decoding test +
    • utf-8 decoding test (only on platforms other than MSDOS) +
    +

    + The coding system cheking results are examined in the following order: +

    +

      +
    1. Only when there is no error state in simple euc decoding, + lv will assumes the input coding system is + default EUC coding system, + which is defined by option -D. +
    2. Only when there is no error state in euc-japan (or euc-taiwan) decoding, + lv will assumes the input coding system is euc-japan + (Japanese version). + Since there is no syntactical difference + between euc-taiwan and euc-japan, + this action is to be altered in Taiwanese environment. +
    3. Only when there is no error state in big5 decoding, + lv will assumes the input coding system is big5. + Since big5 sequences are similar to EUCs, + sometimes its streams will be misunderstood as EUCs. +
    4. Only when there is no error state in shift-jis decoding, + lv will assumes the input coding system is shift-jis. + Since shift-jis shares code-points with EUCs partially, + its streams may be possibly misunderstood as EUCs. +
    5. Only when there is no error state in utf-8 decoding, + lv will assumes the input coding system is utf-8. + Like big5 and shift-jis, + sometimes its steams will be misinterpreted + as another coding system. +
    6. Otherwise, + lv will assumes the input coding system is + ISO 8859-1 (latin-1). +
    +

    + If a text contains only EUC code points, + it is hard to identify the language + the EUC coding system represents. + So lv provides default EUC coding system + used when lv chooses the input coding system from EUCs. + Default EUC coding system is set by option -D + (euc-japan on Japanese version LV). +

    + You can toggle coding systems even while viewing a file + by run-time command `t' and `T', + which traverses through all coding sytems implemented in LV. + In addition, + you can toggle HZ decoding mode by C-t on demand. +

    + You should remember that + the auto-selection mechanism of LV works incorrectly in some cases. + Especially, + if a text contains only JIS X 0201 Katakana in shift-jis, + it will be misinterpreted as euc-japan. +

    + If the result of auto selection is incorrect + and you know the input coding system, + please set it by the option -I, + which disables auto selection. +

+ +
+ + +

+Extension for text decoration

+ +
    +
  • + Option -c enables ANSI escape sequences + in the form of ESC [ ps ; ... ; ps m, + where ps takes following values: +

    +

      +
    • 1: Highlight +
    • 4: Underline +
    • 5: Blink +
    • 7: Reverse +
    • 30: Black +
    • 31: Red +
    • 32: Green +
    • 33: Yellow +
    • 34: Blue +
    • 35: Magenta +
    • 36: Cyan +
    • 37: White +
    • 40-47: Reverse of 30-37 +
    +

    +

  • Every sequence is independent of one another. + lv will reset all values before new value is set. + Meanwhile, + multiple pss are accepted within one sequence. +
  • Every sequence is only effective within a logical line. + On crossing logical lines, + all attributes are reset automatically. + Please recall that lv handles each logical line as stateless. +
  • You can specify one color at once. + When multiple colors are specified, + the last one is effective. +
  • As to reversed characters, + a specified color is applied to the ``reversed background color''. + You cannot specify the color of ``out-clipped characters''. +
  • You can customize actual sequences to be output to the screen. + Please specify them by option -S. +
+ +
+ + +

+Customization

+ +
    +
  • Customization for command key bindings
    + Please modify the keybind table in keybind.h. +

    +

  • Customization for terminal controls
    + When you add a new terminal control, + please add codes to console.c. + When you wish to change interpretation of escape sequences, + please modify console.c and escape.c. + However, some ANSI escape sequences are configurable through options. +

    +

  • Changing default screen size of MSDOS ANSI terminals
    + Default screen size is 80 columns by 24 rows. + To change this, + please modify console.c. + However, screen size can be specified through options. +

    +

  • Changing default coding systems
    + Currently, Japanese version of lv uses following values: +

    +

    + +
    MSDOS UNIX +
    Input: auto-select auto-select +
    Keyboard: shift-jis iso-2022-jp +
    Output: shift-jis iso-2022-jp +
    Pathname: shift-jis iso-2022-jp +
    Default EUC: euc-japan euc-japan +
    +
    +

    + To change above, + please modify lv.c. + However, + those coding systems can be specified through options. +

    +

  • Customization for coding systems
    + Currently, + an ISO 2022 universal decoder, + and EUC, HZ, shift-jis, big5, UTF-7, UTF-8 decoders are implemented. + When you wish to add another coding systems, + please add source codes, + referencing ctable_t.h, ctable.c, encode.c, decode.c, iso2022.c, etc. +

    +

  • Customization for character sets
    + Please add your favorite character sets, + referencing itable_t.h, itable.c, etc. + Currently recognized character sets are itemized below. + You have to specify code length (bytes) and graphical width (columns) + of each character as attributes. + There is no necessity that + code length and graphical width equal each other. + Current implementation does not support per character length, + but you can specify the maximum length of them in itable, + it may not cause problems. + You cannot add charsets whose code length is more than 3 bytes. + (If you desire to do it, + you can add only little modification to lv, + so up to 4bytes charsets can be supported by lv.) +

+Apparently, lv looks like \fIless\fP (1), +a representative file viewer on UNIX as you know, +so UNIX people (and \fIless\fP 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. +.IP "\fIMultiple coding systems\fP" +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 \fInkf\fP (1) and \fItcs\fP (1). +.IP "\fIMultilingual regular expressions / Multilingual grep\fP" +lv can recognize multi-bytes patterns as regular expressions, +and lv also provides multilingual \fIgrep\fP (1) functionality +by giving it another name, \fIlgrep\fP. +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. +.IP "\fISupporting the Unicode standard\fP" +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.) +.IP "\fIANSI escape sequence through\fP" +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. +.IP "\fICompletely original\fP" +lv is a completely original software +including no code drawn
