NAME

       Text::ASCIITable - Create a nice formatted table using ASCII characters.

SHORT DESCRIPTION

       Pretty nifty if you want to output dynamic text to your console or other fixed-size-font
       displays, and at the same time it will display it in a nice human-readable, or "cool" way.

SYNOPSIS

         use Text::ASCIITable;
         $t = Text::ASCIITable->new({ headingText => 'Basket' });

         $t->setCols('Id','Name','Price');
         $t->addRow(1,'Dummy product 1',24.4);
         $t->addRow(2,'Dummy product 2',21.2);
         $t->addRow(3,'Dummy product 3',12.3);
         $t->addRowLine();
         $t->addRow('','Total',57.9);
         print $t;

         # Result:
         .------------------------------.
         |            Basket            |
         +----+-----------------+-------+
         | Id | Name            | Price |
         +----+-----------------+-------+
         |  1 | Dummy product 1 |  24.4 |
         |  2 | Dummy product 2 |  21.2 |
         |  3 | Dummy product 3 |  12.3 |
         +----+-----------------+-------+
         |    | Total           |  57.9 |
         '----+-----------------+-------'

FUNCTIONS

   new(options)
       Initialize a new table. You can specify output-options. For more options, check out the
       usage for setOptions()

         Usage:
         $t = Text::ASCIITable->new();

         Or with options:
         $t = Text::ASCIITable->new({ hide_Lastline => 1, reportErrors => 0});

   setCols(@cols)
       Define the columns for the table(compare with <TH> in HTML). For example
       "setCols(['Id','Nick','Name'])".  Note that you cannot add Cols after you have added a
       row. Multiline columnnames are allowed.

   addRow(@collist)
       Adds one row to the table. This must be an array of strings. If you defined 3 columns.
       This array must have 3 items in it. And so on. Should be self explanatory. The strings can
       contain newlines.

         Note: It does not require argument to be an array, thus;
         $t->addRow(['id','name']) and $t->addRow('id','name') does the same thing.

       This module is also overloaded to accept push. To construct a table with the use of
       overloading you might do the following:

         $t = Text::ASCIITable->new();
         $t->setCols('one','two','three','four');
         push @$t, ( "one\ntwo" ) x 4; # Replaces $t->addrow();
         print $t;                     # Replaces print $t->draw();

         Which would construct:
          .-----+-----+-------+------.
          | one | two | three | four |
          |=----+-----+-------+-----=|
          | one | one | one   | one  |  # Note that theese two lines
          | two | two | two   | two  |  # with text are one singe row.
          '-----+-----+-------+------'

       There is also possible to give this function an array of arrayrefs and hence support the
       output from DBI::selectall_arrayref($sql) without changes.

         Example of multiple-rows pushing:
         $t->addRow([
           [ 1, 2, 3 ],
           [ 4, 5, 6 ],
           [ 7, 8, 9 ],
         ]);

   addRowLine([$row])
       Will add a line after the current row. As an argument, you may specify after which row you
       want a line (first row is 1) or an array of row numbers. (HINT: If you want a line after
       every row, read about the drawRowLine option in setOptions())

       Example without arguments:
         $t->addRow('one','two'X'three');
         $t->addRowLine();
         $t->addRow('one','two'X'three');

       Example with argument:
         $t->addRow('one','two'X'three');
         $t->addRow('one','two'X'three');
         $t->addRow('one','two'X'three');
         $t->addRow('one','two'X'three');
         $t->addRowLine(1); # or multiple: $t->addRowLine([2,3]);

   alignCol($col,$direction) or alignCol({col1 => direction1, col2 => direction2, ... })
       Given a columnname, it aligns all data to the given direction in the table. This looks
       nice on numerical displays in a column. The column names in the table will be unaffected
       by the alignment. Possible directions is: left, center, right, justify, auto or your own
       subroutine. (Hint: Using auto(default), aligns numbers right and text left)

   alignColName($col,$direction)
       Given a columnname, it aligns the columnname in the row explaining columnnames, to the
       given direction. (auto,left,right,center,justify or a subroutine) (Hint: Overrides the
       'alignHeadRow' option for the specified column.)

   setColWidth($col,$width,$strict)
       Wordwrapping/strict size. Set a max-width(in chars) for a column.  If last parameter is 1,
       the column will be set to the specified width, even if no text is that long.

        Usage:
         $t->setColWidth('Description',30);

   getTableWidth()
       If you need to know how wide your table will be before you draw it. Use this function.

   setOptions(name,value) or setOptions({ option1 => value1, option2 => value2, ... })
       Use this to set options like: hide_FirstLine,reportErrors, etc.

         Usage:
         $t->setOptions('hide_HeadLine',1);

         Or set more than one option on the fly:
         $t->setOptions({ hide_HeadLine => 1, hide_HeadRow => 1 });

       Possible Options

       hide_HeadRow
           Hides output of the columnlisting. Together with hide_HeadLine, this makes a table
           only show the rows. (However, even though the column-names will not be shown, they
           will affect the output if they have for example ridiculoustly long names, and the rows
           contains small amount of info. You would end up with a lot of whitespace)

       reportErrors
           Set to 0 to disable error reporting. Though if a function encounters an error, it will
           still return the value 1, to tell you that things didn't go exactly as they should.

       allowHTML
           If you are going to use Text::ASCIITable to be shown on HTML pages, you should set
           this option to 1 when you are going to use HTML tags to for example color the text
           inside the rows, and you want the browser to handle the table correct.

       allowANSI
           If you use ANSI codes like <ESC>[1mHi this is bold<ESC>[m or similar. This option will
           make the table to be displayed correct when showed in a ANSI compliant terminal. Set
           this to 1 to enable. There is an example of ANSI support in this package, named
           ansi-example.pl.

       alignHeadRow
           Set wich direction the Column-names(in the headrow) are supposed to point. Must be
           left, right, center, justify, auto or a user-defined subroutine.

       hide_FirstLine, hide_HeadLine, hide_LastLine
           Speaks for it self?

       drawRowLine
           Set this to 1 to print a line between each row. You can also define the outputstyle of
           this line in the draw() function.

       headingText
           Add a heading above the columnnames/rows wich uses the whole width of the table to
           output a heading/title to the table. The heading-part of the table is automatically
           shown when the headingText option contains text. Note: If this text is so long that it
           makes the table wider, it will not hesitate to change width of columns that have
           "strict width".

           It supports multiline, and with Text::ASCIITable::Wrap you may wrap your text before
           entering it, to prevent the title from expanding the table. Internal wrapping-support
           for headingText might come in the future.

       headingAlign
           Align the heading(as mentioned above) to left, right, center, auto or using a
           subroutine.

       headingStartChar, headingStopChar
           Choose the startingchar and endingchar of the row where the title is. The default is
           '|' on both. If you didn't understand this, try reading about the draw() function.

       cb_count
           Set the callback subroutine to use when counting characters inside the table. This is
           useful to make support for having characters or codes inside the table that are not
           shown on the screen to the user, so the table should not count these characters. This
           could be for example HTML tags, or ANSI codes. Though those two examples are alredy
           supported internally with the allowHTML and allowANSI, options. This option expects a
           CODE reference. (\&callback_function)

       undef_as
           Sets the replacing string that replaces an undef value sent to addRow() (or even the
           overloaded push version of addRow()). The default value is an empty string ''. An
           example of use would be to set it to '(undef)', to show that the input really was
           undefined.

       chaining
           Set this to 1 to support chainging of methods. The default is 0, where the methods
           return 1 if they come upon an error as mentioned in the reportErrors option
           description.

             Usage example:
             print Text::ASCIITable->new({ chaining => 1 })
               ->setCols('One','Two','Three')
               ->addRow([
                 [ 1, 2, 3 ],
                 [ 4, 5, 6 ],
                 [ 7, 8, 9 ],
                 ])
               ->draw();

           Note that ->draw() can be omitted, since Text::ASCIITable is overloaded to print the
           table by default.

   draw([@topdesign,@toprow,@middle,@middlerow,@bottom,@rowline])
       All the arrays containing the layout is optional. If you want to make your own "design" to
       the table, you can do that by giving this method these arrays containing information about
       which characters to use where.

       Custom tables

       The draw method takes 6 arrays of strings to define the layout. The first, third, fifth
       and sixth is LINE layout and the second and fourth is ROW layout. The "fourth" parameter
       is repeated for each row in the table.  The sixth parameter is only used if drawRowLine is
       enabled.

        $t->draw(<LINE>,<ROW>,<LINE>,<ROW>,<LINE>,[<ROWLINE>])

       LINE
           Takes an array of 4 strings. For example "['|','|','-','+']"

           ·   LEFT - Defines the left chars. May be more than one char.

           ·   RIGHT - Defines the right chars. May be more then one char.

           ·   LINE - Defines the char used for the line. Must be only one char.

           ·   DELIMETER - Defines the char used for the delimeters. Must be only one char.

       ROW Takes an array of 3 strings. You should not give more than one char to any of these
           parameters, if you do.. it will probably destroy the output.. Unless you do it with
           the knowledge of how it will end up. An example: "['|','|','+']"

           ·   LEFT - Define the char used for the left side of the table.

           ·   RIGHT - Define the char used for the right side of the table.

           ·   DELIMETER - Defines the char used for the delimeters.

       Examples:

       The easiest way:

        print $t;

       Explanatory example:

        print $t->draw( ['L','R','l','D'],  # LllllllDllllllR
                        ['L','R','D'],      # L info D info R
                        ['L','R','l','D'],  # LllllllDllllllR
                        ['L','R','D'],      # L info D info R
                        ['L','R','l','D']   # LllllllDllllllR
                       );

       Nice example:

        print $t->draw( ['.','.','-','-'],   # .-------------.
                        ['|','|','|'],       # | info | info |
                        ['|','|','-','-'],   # |-------------|
                        ['|','|','|'],       # | info | info |
                        [' \\','/ ','_','|'] #  \_____|_____/
                       );

       Nice example2:

        print $t->draw( ['.=','=.','-','-'],   # .=-----------=.
                        ['|','|','|'],         # | info | info |
                        ['|=','=|','-','+'],   # |=-----+-----=|
                        ['|','|','|'],         # | info | info |
                        ["'=","='",'-','-']    # '=-----------='
                       );

       With Options:

        $t->setOptions('drawRowLine',1);
        print $t->draw( ['.=','=.','-','-'],   # .=-----------=.
                        ['|','|','|'],         # | info | info |
                        ['|-','-|','=','='],   # |-===========-|
                        ['|','|','|'],         # | info | info |
                        ["'=","='",'-','-'],   # '=-----------='
                        ['|=','=|','-','+']    # rowseperator
                       );
        Which makes this output:
          .=-----------=.
          | col1 | col2 |
          |-===========-|
          | info | info |
          |=-----+-----=| <-- rowseperator between each row
          | info | info |
          '=-----------='

       A tips is to enable allowANSI, and use the extra charset in your terminal to create a
       beautiful table. But don't expect to get good results if you use ANSI-formatted table with
       $t->drawPage.

       User-defined subroutines for aligning

       If you want to format your text more throughoutly than "auto", or think you have a better
       way of aligning text; you can make your own subroutine.

         Here's a exampleroutine that aligns the text to the right.

         sub myownalign_cb {
           my ($text,$length,$count,$strict) = @_;
           $text = (" " x ($length - $count)) . $text;
           return substr($text,0,$length) if ($strict);
           return $text;
         }

         $t->alignCol('Info',\&myownalign_cb);

       User-defined subroutines for counting

       This is a feature to use if you are not happy with the internal allowHTML or allowANSI
       support. Given is an example of how you make a count-callback that makes ASCIITable
       support ANSI codes inside the table. (would make the same result as setting allowANSI to
       1)

         $t->setOptions('cb_count',\&myallowansi_cb);
         sub myallowansi_cb {
           $_=shift;
           s/\33\[(\d+(;\d+)?)?[musfwhojBCDHRJK]//g;
           return length($_);
         }

   drawPage($page,@topdesign,@toprow,@middle,@middlerow,@bottom,@rowline)
       If you don't want your table to be wider than your screen you can use this with
       $t->setOptions('outputWidth',40) to set the max size of the output.

       Example:

         $t->setOptions('outputWidth',80);
         for my $page (1..$t->pageCount()) {
           print $t->drawPage($page)."\n";
           print "continued..\n\n";
         }

FEATURES

       In case you need to know if this module has what you need, I have made this list of
       features included in Text::ASCIITable.

       Configurable layout
           You can easily alter how the table should look, in many ways. There are a few examples
           in the draw() section of this documentation. And you can remove parts of the layout or
           even add a heading-part to the table.

       Text Aligning
           Align the text in a column auto(matically), left, right, center or justify. Usually
           you want to align text to right if you only have numbers in that row. The 'auto'
           direction aligns text to left, and numbers to the right. The 'justify' alignment evens
           out your text on each line, so the first and the last word always are at the beginning
           and the end of the current line. This gives you the newspaper paragraph look.  You can
           also use your own subroutine as a callback-function to align your text.

       Multiline support in rows
           With the \n(ewline) character you can have rows use more than just one line on the
           output. (This looks nice with the drawRowLine option enabled)

       Wordwrap support
           You can set a column to not be wider than a set amount of characters. If a line
           exceedes for example 30 characters, the line will be broken up in several lines.

       HTML support
           If you put in <HTML> tags inside the rows, the output would usually be broken when
           viewed in a browser, since the browser "execute" the tags instead of displaying it.
           But if you enable allowHTML. You are able to write html tags inside the rows without
           the output being broken if you display it in a browser. But you should not mix this
           with wordwrap, since this could make undesirable results.

       ANSI support
           Allows you to decorate your tables with colors or bold/underline when you display your
           tables to a terminal window.

       Page-flipping support
           If you don't want the table to get wider than your terminal-width.

       Errorreporting
           If you write a script in perl, and don't want users to be notified of the
           errormessages from Text::ASCIITable. You can easily turn of error reporting by setting
           reportErrors to 0.  You will still get an 1 instead of undef returned from the
           function.
