It supports traditional options and some of Linux extended, and other original options. Empty lines are **not** ignored, though. ## COMPATIBLE OPTIONS The column utility formats its input into multiple columns. Rows are filled before columns. Input is taken from _file_ operands, or, by default, from the standard input. - **-c**#, **--width**=#, **--output-width**=# Output is formatted for a display columns wide. See ["CALCULATION"](#calculation) section. - **-s**#, **--separator**=# Specify a set of characters to be used to delimit columns for the \-t option. - **-t**, **--table** Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the characters supplied using the -s option. Useful for pretty-printing displays. - **-l**_#_, **--table-columns-limit** _number_ Specify maximal number of the input columns. The last column will contain all remaining line data if the limit is smaller than the number of the columns in the input data. - **-x**, **--fillrows** Fill columns before filling rows. - **-o**#, **--output-separator**=# When used **--table** or **-t** option, each columns are joined by two space characters (' ') by default. This option will change it. - **-R**_columns_, **--table-right**=_columns_ Right align text in these columns. Support only numbers. ## EXTENDED OPTION - **-P**\[_#_\], **--page**\[=_#_\] Page mode. Set these options. --height=# or 1- --linestyle=wrap --border --fillup If optional number is given, it is used as a page height unless option **--height** exists. Otherwise page height is set to terminal height minus one. - **-U**#, **--up**=#, **--2up** .. **--9up** Show in N-up format. Almost same as **-P** but does not set page height. This is convenient when you want multi-column output without page control. - **-D**, **--document** Document mode. Set these options. --widen --linebreak=all --linestyle=wrap --boundary=word --no-white-space --no-isolation Next command display DOCX text in 3-up format using [App::optex::textconv](https://metacpan.org/pod/App%3A%3Aoptex%3A%3Atextconv). optex -Mtextconv ansicolumn -DPC3 foo.docx | less - **-C**#, **--pane**=# Output is formatted in the specified number of panes. Setting number of panes implies **--widen** option enabled. See ["CALCULATION"](#calculation) section. - **-S**#, **--pane-width**=#, **--pw**=# Specify pane width. This includes border spaces. See ["CALCULATION"](#calculation) section. - **-W**, **--widen** Use full width of the terminal. Each panes are expanded to fill terminal width, unless **--pane-width** is specified. - **-p**, **--paragraph** Insert empty line between every successive non-empty lines. - **-B**, **--border**\[=_style_\] Print border. Enabled by **--page** option automatically. If the optional _style_ is given, it is used as a border style and precedes to **--border-style** option. Use **--border=none** to disable it. Border style is specified by **--border-style** option. - **-F**, **--fillup**\[=`pane`|`page`|`none`\] Fill up final pane or page by empty lines. Parameter is optional and considered as 'pane' by default. Set by **--page** option automatically. Use **--fillup=none** if you want to explicitly disable it. Option **-U** is a shortcut for **--border=pane**. - **--height**=# Set page height and page mode on. See ["CALCULATION"](#calculation) section. - **--column-unit**=#, **--cu**=# Each columns are placed at the unit of 8 by default. This option changes the number of the unit. - **--linestyle**=`none`|`truncate`|`wrap`|`wordwrap`, **--ls**=`...` Set the style of treatment for longer lines. Default is `none`. **--linestyle=wordrap** is equivalent to **--linestyle=wrap** **--boundary=word**. - **--boundary**=`none`|`word`|`space` Set text wrap boundary. If set as `word` or `space`, text is not wrapped in the middle of alphanumeric word or non-space sequence. Option **--document** set this as `word`. See [Text::ANSI::Fold](https://metacpan.org/pod/Text%3A%3AANSI%3A%3AFold) for detail. - **--linebreak**=`none`|`all`|`runin`|`runout`, **--lb**=... Set the linebreak mode. - **--runin**=#, **--runout**=# Set the number of runin/runout column. Default is both 2. - **--**\[**no-**\]**pagebreak** Move to next pane when form feed character found. Default true. - **--border-style**=_style_, **--bs**=... Set the border style. Current default style is `vbar`, which is light vertical line filling the page height. Sample styles: none, space, vbar, heavy-vbar, fat-vbar, line, heavy-line, stick, heavy-stick, ascii-frame, ascii-box, c-box, box, heavy-box, fat-box, very-fat-box, round-box, heavy-round-box, frame, heavy-frame, fat-frame, very-fat-frame, page-frame, heavy-page-frame, shadow, shadow-box, heavy-shadow-box, comb, heavy-comb, rake, heavy-rake, mesh, heavy-mesh, dumbbell, heavy-dumbbell, ribbon, heavy-ribbon, round-ribbon, double-ribbon, etc. These are experimental and subject to change, and this document is not always up-to-date. See \`perldoc -m App::ansicolumn::Border\` for actual data. You can define your own style in module or startup file. Put next lines in your `$HOME/.ansicolumnrc` file, for example. option default --border-style myheart __PERL__ App::ansicolumn::Border->add_style( myheart => { left => [ "\N{WHITE HEART SUIT} ", "\N{BLACK HEART SUIT} " ], center => [ "\N{WHITE HEART SUIT} ", "\N{BLACK HEART SUIT} " ], right => [ "\N{WHITE HEART SUIT}" , "\N{BLACK HEART SUIT}" ], }, ); - **--**\[**no-**\]**ignore-space**, **--**\[**no-**\]**is** When used **-t** option, leading spaces are ignored by default. Use **--no-ignore-space** option to disable it. - **--**\[**no-**\]**white-space** Allow white spaces at the top of each panes, or clean them up. Default true. Negated by **--document** option. - **--**\[**no-**\]**isolation** Allow the first line of a paragraph (continuous non-space lines) is placed at the bottom of a pane. Default true. If false, move it to the top of next pane. Negated by **--document** option. - **--tabstop**=# Set tab width. - **--tabhead**=# - **--tabspace**=# Set head and following space characters. Both are space by default. If the option value is longer than single characger, it is evaluated as unicode name. - **--tabstyle**=# Set the style how tab is expanded. Select from `dot`, `symbol` or `shade`. Styles are defined in [Text::ANSI::Fold](https://metacpan.org/pod/Text%3A%3AANSI%3A%3AFold) library. - **--ambiguous**=`wide`|`narrow` Specifies how to treat Unicode ambiguous width characters. Take a value of 'narrow' or 'wide. Default is 'narrow'. # CALCULATION As for **--height**, **--width**, **--pane** and **--pane-width** options, besides giving numeric digits, you can calculate the number using terminal size. If the expression contains non-digit character, it is evaluated as a Reverse Polish Notation with the terminal size pushed on the stack. Initial value for **--height** options is terminal height, and terminal width for others. OPTION VALUE ================= ========================= --height 1- height - 1 --height 2/ height / 2 --height 1-2/ (height - 1) / 2 --height dup2%-2/ (height - height % 2) / 2 Space and comma characters are ignored in the expression. So `1-2/` and `1 - 2 /` and `1,-,2,/` are all same. See \`perldoc Math::RPN\` for the expression detail. Next example select number of panes by dividing terminal width by 85: ansicolumn --pane 85/ If you consider the case the terminal width is less than 85: ansicolumn --pane 85/,DUP,1>,EXCH,1,IF # STARTUP This command is implemented with [Getopt::EX](https://metacpan.org/pod/Getopt%3A%3AEX) module. So ~/.ansicolumnrc file is read at start up. If you want use **--no-white-space** always, put this line in your `~/.ansicolumnrc`. option default --no-white-space Also command can be extended by original modules with **-M** option. See \`perldoc Getopt::EX\` for detail. # INSTALL ## CPANMINUS $ cpanm App::ansicolumn or $ curl -sL http://cpanmin.us | perl - App::ansicolumn To get the latest code, use this: $ cpanm https://github.com/kaz-utashiro/App-ansicolumn.git # EXAMPLES [https://github.com/kaz-utashiro/App-ansicolumn/tree/master/images](https://github.com/kaz-utashiro/App-ansicolumn/tree/master/images) # SEE ALSO [column(1)](http://man.he.net/man1/column), [https://man7.org/linux/man-pages/man1/column.1.html](https://man7.org/linux/man-pages/man1/column.1.html) [App::ansicolumn](https://metacpan.org/pod/App%3A%3Aansicolumn), [https://github.com/kaz-utashiro/App-ansicolumn](https://github.com/kaz-utashiro/App-ansicolumn) [Text::ANSI::Printf](https://metacpan.org/pod/Text%3A%3AANSI%3A%3APrintf), [https://github.com/kaz-utashiro/Text-ANSI-Printf](https://github.com/kaz-utashiro/Text-ANSI-Printf) # AUTHOR Kazumasa Utashiro # LICENSE Copyright 2020-2022 Kazumasa Utashiro.
