NAME

       Term::Complete - Perl word completion module

SYNOPSIS

	   $input = Complete('prompt_string', @completion_list);
	   $input = Complete('prompt_string', @completion_list);

DESCRIPTION

       This routine provides word completion on the list of words in the array (or array ref).

       The tty driver is put into raw mode and restored using an operating system specific command, in UNIX-like environments "stty".

       The following command characters are defined:

       <tab>
	   Attempts word completion.  Cannot be changed.

       ^D  Prints completion list.  Defined by $Term::Complete::complete.

       ^U  Erases the current input.  Defined by $Term::Complete::kill.

       <del>, <bs>
	   Erases one character.  Defined by $Term::Complete::erase1 and $Term::Complete::erase2.

DIAGNOSTICS

       Bell sounds when word completion fails.

BUGS

       The completion character <tab> cannot be changed.

NAME

       Term::Size - Retrieve terminal size (Unix version)

SYNOPSIS

	   use Term::Size;

	   ($columns, $rows) = Term::Size::chars *STDOUT{IO};
	   ($x, $y) = Term::Size::pixels;

DESCRIPTION

       Term::Size is a Perl module which provides a straightforward way to retrieve the terminal size.

       Both functions take an optional filehandle argument, which defaults to *STDIN{IO}.  They both return a list of two values, which are the
       current width and height, respectively, of the terminal associated with the specified filehandle.

       "Term::Size::chars" returns the size in units of characters, whereas "Term::Size::pixels" uses units of pixels.

       In a scalar context, both functions return the first element of the list, that is, the terminal width.

       The functions may be imported.

       If you need to pass a filehandle to either of the "Term::Size" functions, beware that the *STDOUT{IO} syntax is only supported in Perl
       5.004 and later.  If you have an earlier version of Perl, or are interested in backwards compatibility, use *STDOUT instead.

EXAMPLES

       1. Refuse to run in a too narrow window.

	   use Term::Size;

	   die "Need 80 column screen" if Term::Size::chars *STDOUT{IO} < 80;

       2. Track window size changes.

	   use Term::Size 'chars';

	   my $changed = 1;

	   while(1) {
		   local $SIG{'WINCH'} = sub { $changed = 1 };

		   if ($changed) {
			   ($cols, $rows) = chars;
			   # Redraw, or whatever.
			   $changed = 0;
		   }
	   }

RETURN VALUES

       Both functions return "undef" if there is an error.

       If the terminal size information is not available, the functions will normally return "(0, 0)", but this depends on your system.  On
       character only terminals, "pixels" will normally return "(0, 0)".

BUGS

       It only works on Unix systems.
