NAME

Indent::Form - A perl module for form indenting.

SYNOPSIS

use Indent::Form;

my $indent = Indent::Form->new(%parametes);
my $string = $indent->indent($data_ar, $actual_indent, $non_indent_flag);
my @string = $indent->indent($data_ar, $actual_indent, $non_indent_flag);

METHODS

new

my $indent = Indent::Form->new(%parametes);

Constructor.

Returns instance of object.

• ansi

  Use with ANSI sequences.
  Default value is 0.

• align

  Align of left side of form.
  Default value is 'right'.

• fill_character

  Fill character for left side of form.
  Default value is ' '.

• form_separator

  Form separator.
  Default value of 'form_separator' is ': '.

• line_size

  Line size.
  Default value of 'line_size' is 79 chars.

• next_indent

  Next indent.
  Default value of 'next_indent' isn't define.

• output_separator

  Output separator.
  Default value of 'output_separator' is new line (\n).

indent

my $string = $indent->indent($data_ar, $actual_indent, $non_indent_flag);
my @string = $indent->indent($data_ar, $actual_indent, $non_indent_flag);

Indent data. Scalar output is controlled by 'output_separator' parameter.

Arguments:
$data_ar - Reference to data array ([['key' => 'value'], [..]]);
$actual_indent - String to actual indent.
$non_indent_flag - Flag, than says no-indent.

Returns string or array of strings in array context.

ENVIRONMENT

Output is controlled by env variable NO_COLOR via Term::ANSIColor Perl module. If we set 'ansi' parameter to 1 and env variable NO_COLOR will be 1, output will be without ANSI colors. See https://no-color.org/.

ERRORS

new():
        'align' parameter must be a 'left' or 'right' string.
        'line_size' parameter must be a number.
        Cannot load 'Text::ANSI::Util' module.
        From Class::Utils:
                Unknown parameter '%s'.
