oracle:11g$ ./doit2
COLUMNS =

oracle:11g$ echo $COLUMNS
80

oracle:11g$

Perhaps COLUMNS is not exported, try export COLUMNS before running doit2

If COLUMNS is not set scripts/programs could be using tput cols or similar to query the terminal for it's actual width.

Also see bash shopt checkwinsize, this keeps COLUMNS and LINES updated automatically, this is useful for an xterm where the users could resize the window after the shell has started.

html::formfu::element::combobox

HTML::FormFu::Element::ComboBox(3pm)			User Contributed Perl Documentation		      HTML::FormFu::Element::ComboBox(3pm)

NAME

       HTML::FormFu::Element::ComboBox - Select / Text hybrid

SYNOPSIS

	   ---
	   elements:
	     - type: ComboBox
	       name: answer
	       label: 'Select yes or no, or write an alternative:'
	       values:
		 - yes
		 - no

DESCRIPTION

       Creates a multi element containing a Select field and a Text field.

       A ComboBox element named "foo" would result in a Select menu named "foo_select" and a Text field named "foo_text". The names can instead be
       overridden by the "name" value in "select" and "text".

       If a value is submitted for the Text field, this will be used in preference to any submitted value for the Select menu.

       You can access the submitted value by using the ComboBox's name:

	   my $value = $form->param_value('foo');

METHODS

   default
       If the value matches one of the Select menu's options, that options will be selected. Otherwise, the Text field will use the value as its
       default.

   options
       See "options" in HTML::FormFu::Element::_Group for details.

   values
       See "values" in HTML::FormFu::Element::_Group for details.

   value_range
       See "value_range" in HTML::FormFu::Element::_Group for details.

   empty_first
       See "empty_first" in HTML::FormFu::Element::_Group for details.

   empty_first_label
       See "empty_first_label" in HTML::FormFu::Element::_Group for details.

   select
       Arguments: \%setting

       Set values effecting the Select menu. Known keys are:

       name

       Override the auto-generated name of the select menu.

   text
       Arguments: \%setting

       Set values effecting the Text field. Known keys are:

       name

       Override the auto-generated name of the select menu.

CAVEATS

       Although this element inherits from HTML::FormFu::Element::Block, its behaviour for the methods filter/filters, constraint/constraints,
       inflator/inflators, validator/validators and transformer/transformers is more like that of a field element, meaning all processors are
       added directly to the date element, not to its child elements.

       This element's get_elements and get_all_elements are inherited from HTML::FormFu::Element::Block, and so have the same behaviour. However,
       it overrides the "get_fields|HTML::FormFu/get_fields" method, such that it returns both itself and its child elements.

SEE ALSO

       Is a sub-class of, and inherits methods from HTML::FormFu::Element::Multi, HTML::FormFu::Element::Block, HTML::FormFu::Element
