NAME

Term::ReadLine::Tiny - Read a line from STDIN.

VERSION

Version 0.010_05

SYNOPSIS

    use Term::ReadLine::Tiny;

    my $new = Term::ReadLine::Tiny->new( 'name' );
    my $line = $new->readline( 'Prompt: ', { default => 'abc' } );

DESCRIPTION

readline reads a line from STDIN. As soon as Return is pressed readline returns the read string without the newline character - so no chomp is required.

Keys

BackSpace or Strg-H: Delete the character behind the cursor.

Delete or Strg-D: Delete the character at point. Return nothing if the input puffer is empty.

Strg-U: Delete the text backward from the cursor to the beginning of the line.

Strg-K: Delete the text from the cursor to the end of the line.

Right-Arrow or Strg-F: Move forward a character.

Left-Arrow or Strg-B: Move back a character.

Home or Strg-A: Move to the start of the line.

End or Strg-E: Move to the end of the line.

METHODS

new

The new method returns a Term::ReadLine::Tiny object.

    my $new = Term::ReadLine::Tiny->new( 'name' );

The argument is the name of the application.

config

The method config sets the defaults for the current Term::ReadLine::Tiny object.

    $new->config( \%options );

The available options are:

• default

  Sets the default default string.

  Allowed values: a decoded string.

  Default: not set.

• no_echo

  Sets the default value for no_echo.

  Allowed values: 0, 1 or 2.

  Default: 0.

Options not available in the readline method:

• compat

  If compat is set to 1, the return value of readline is not decoded else the return value of readline is decoded.

  Setting the environment variable READLINE_TINY_COMPAT to a true value has the same effect as setting compat to 1 unless compat is defined. If compat is defined, READLINE_TINY_COMPAT has no meaning.

  Allowed values: 0 or 1.

  Default: no set

• reinit_encoding

  To get the right encoding Term::ReadLine::Tiny uses Encode::Locale. Passing an encoding to reinit_encoding changes the encoding reported by Encode::Locale. See "reinit-encoding" in Encode::Locale for more details.

  Allowed values: an encoding which is recognized by the Encode module.

  Default: not set.

readline

readline reads a line from STDIN.

    $line = $new->readline( $prompt, [ \%options ] );

The fist argument is the prompt string. The optional second argument is the default string if it is not a reference. If the second argument is a hash-reference, the hash is used to set the different options. The keys/options are

• default

  Sets a initial value of input.

• no_echo

  If no_echo is set to 1, "*" are displayed instead of the characters.

  If no_echo is set to 2, no output is shown apart from the prompt string.

See "config" for the default and allowed values.

REQUIREMENTS

Perl version

Requires Perl version 5.08.0 or greater.

Terminal

It is required a terminal which uses a monospaced font and understands ANSI escape sequences.

Encoding layer

It is required to use appropriate I/O encoding layers. If the encoding layer for STDIN doesn't match the terminal's character set, readline will break if a non ascii character is entered.

SUPPORT

You can find documentation for this module with the perldoc command.
