=head1 NAME

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

=head1 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.

=head1 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 |
  '----+-----------------+-------'

=head1 FUNCTIONS

=head2 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});

=cut

sub new {
  my $self = {
		tbl_cols => [],
		tbl_rows => [],
		tbl_cuts => [],
		tbl_align => {},
		tbl_lines => {},

		des_top       => ['.','.','-','-'],
		des_middle    => ['+','+','-','+'],
		des_bottom    => ["'","'",'-','+'],
		des_rowline   => ['+','+','-','+'],

		des_toprow    => ['|','|','|'],
		des_middlerow => ['|','|','|'],

		cache_width   => {},

		options => $_[1] || { }
  };

  $self->{options}{reportErrors} = defined($self->{options}{reportErrors}) ? $self->{options}{reportErrors} : 1; # default setting
  $self->{options}{alignHeadRow} = $self->{options}{alignHeadRow} || 'auto'; # default setting
  $self->{options}{undef_as} = $self->{options}{undef_as} || ''; # default setting
  $self->{options}{chaining} = $self->{options}{chaining} || 0; # default setting
  $self->{options}{utf8} = defined($self->{options}{utf8}) ? $self->{options}{utf8} : 1; # default setting

  bless $self;

  return $self;
}

=head2 setCols(@cols)

Define the columns for the table(compare with
B that you cannot add Cols after you have added a row. Multiline columnnames are allowed.

=cut

sub setCols {
  my $self = shift;
  do { $self->reperror("setCols needs an array"); return $self->{options}{chaining} ? $self : 1; } unless defined($_[0]);
  @_ = @{$_[0]} if (ref($_[0]) eq 'ARRAY');
  do { $self->reperror("setCols needs an array"); return $self->{options}{chaining} ? $self : 1; } unless scalar(@_) != 0;
  do { $self->reperror("Cannot edit cols at this state"); return $self->{options}{chaining} ? $self : 1; } unless scalar(@{$self->{tbl_rows}}) == 0;

  my @lines = map { [ split(/\n/,$_) ] } @_;

  # Multiline support
  my $max=0;
  my @out;
  grep {$max = scalar(@{$_}) if scalar(@{$_}) > $max} @lines;
  foreach my $num (0..($max-1)) {
    my @tmp = map defined $$_[$num] && $$_[$num], @lines;
    push @out, \@tmp;
  }

  @{$self->{tbl_cols}} = @_;
	@{$self->{tbl_multilinecols}} = @out if ($max);
  $self->{tbl_colsismultiline} = $max;

  return $self->{options}{chaining} ? $self : undef;
}

=head2 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 ],
  ]);

=head2 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'¸'three');
  $t->addRowLine();
  $t->addRow('one','two'¸'three');

Example with argument:
  $t->addRow('one','two'¸'three');
  $t->addRow('one','two'¸'three');
  $t->addRow('one','two'¸'three');
  $t->addRow('one','two'¸'three');

=head2 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)

}

=head2 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 });

B

=over 4

=item 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)

=item 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.

=item 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.

=item allowANSI

If you use ANSI codes like [1mHi this is bold[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.

=item 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.

=item hide_FirstLine, hide_HeadLine, hide_LastLine

Speaks for it self?

=item 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.

=item 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. B 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.

=item headingAlign

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

=item 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.

=item 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)

=item 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.


=item 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.

=head2 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.

B

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

 $t->draw(,,,,,[])

=over 4

=item LINE

Takes an array of C<4> strings. For example C<['|','|','-','+']>

=over 4

=item *

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

=item *

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

=item *

LINE - Defines the char used for the line. B.

=item *

DELIMETER - Defines the char used for the delimeters. B.

=back

=item ROW

Takes an array of C<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: C<['|','|','+']>

=over 4

=item *

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

=item *

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

=item *

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.

B

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);

B

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($_);
  }

=cut

sub drawit {scalar shift()->draw()}

=head2 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";
  }

=cut

sub drawPage {
  my $self = shift;
  my ($pagenum,$top,$toprow,$middle,$middlerow,$bottom,$rowline) = @_;
  return $self->draw($top,$toprow,$middle,$middlerow,$bottom,$rowline,$pagenum);
}
