=head1 NAME
Term::Complete - Perl word completion module
=head1 SYNOPSIS
$input = Complete('prompt_string', \@completion_list);
$input = Complete('prompt_string', @completion_list);
=head1 DESCRIPTION
This routine provides word completion on the list of words in
the array (or array ref).
The tty driver is put into raw mode and restored using an operating
system specific command, in UNIX-like environments C<stty>.
The following command characters are defined:
=over 4
=item E<lt>tabE<gt>
Attempts word completion.
Cannot be changed.
=item ^D
Prints completion list.
Defined by I<$Term::Complete::complete>.
=item ^U
Erases the current input.
Defined by I<$Term::Complete::kill>.
=item E<lt>delE<gt>, E<lt>bsE<gt>
Erases one character.
Defined by I<$Term::Complete::erase1> and I<$Term::Complete::erase2>.
=back
=head1 DIAGNOSTICS
Bell sounds when word completion fails.
=head1 BUGS
The completion character E<lt>tabE<gt> cannot be changed.

PK u8�ZL�ze�6 �6 ReadLine.pmnu �[��� =head1 NAME
Term::ReadLine - Perl interface to various C<readline> packages.
If no real package is found, substitutes stubs instead of basic functions.
=head1 SYNOPSIS
use Term::ReadLine;
my $term = Term::ReadLine->new('Simple Perl calc');
my $prompt = "Enter your arithmetic expression: ";
my $OUT = $term->OUT || \*STDOUT;
while ( defined ($_ = $term->readline($prompt)) ) {
my $res = eval($_);
warn $@ if $@;
print $OUT $res, "\n" unless $@;
$term->addhistory($_) if /\S/;
}
=head1 DESCRIPTION
This package is just a front end to some other packages. It's a stub to
set up a common interface to the various ReadLine implementations found on
CPAN (under the C<Term::ReadLine::*> namespace).
=head1 Minimal set of supported functions
All the supported functions should be called as methods, i.e., either as
$term = Term::ReadLine->new('name');
or as
$term->addhistory('row');
where $term is a return value of Term::ReadLine-E<gt>new().
=over 12
=item C<ReadLine>
returns the actual package that executes the commands. Among possible
values are C<Term::ReadLine::Gnu>, C<Term::ReadLine::Perl>,
C<Term::ReadLine::Stub>.
=item C<new>
returns the handle for subsequent calls to following
functions. Argument is the name of the application. Optionally can be
followed by two arguments for C<IN> and C<OUT> filehandles. These
arguments should be globs.
=item C<readline>
gets an input line, I<possibly> with actual C<readline>
support. Trailing newline is removed. Returns C<undef> on C<EOF>.
=item C<addhistory>
adds the line to the history of input, from where it can be used if
the actual C<readline> is present.
=item C<IN>, C<OUT>
return the filehandles for input and output or C<undef> if C<readline>
input and output cannot be used for Perl.
=item C<MinLine>
If argument is specified, it is an advice on minimal size of line to
be included into history. C<undef> means do not include anything into
history. Returns the old value.
=item C<findConsole>
returns an array with two strings that give most appropriate names for
files for input and output using conventions C<"E<lt>$in">, C<"E<gt>out">.
The strings returned may not be useful for 3-argument open().
=item Attribs
returns a reference to a hash which describes internal configuration
of the package. Names of keys in this hash conform to standard
conventions with the leading C<rl_> stripped.
=item C<Features>
Returns a reference to a hash with keys being features present in
current implementation. Several optional features are used in the
minimal interface: C<appname> should be present if the first argument
to C<new> is recognized, and C<minline> should be present if
C<MinLine> method is not dummy. C<autohistory> should be present if
lines are put into history automatically (maybe subject to
C<MinLine>), and C<addhistory> if C<addhistory> method is not dummy.
If C<Features> method reports a feature C<attribs> as present, the
method C<Attribs> is not dummy.
=back
=head1 Additional supported functions
Actually C<Term::ReadLine> can use some other package, that will
support a richer set of commands.
All these commands are callable via method interface and have names
which conform to standard conventions with the leading C<rl_> stripped.
The stub package included with the perl distribution allows some
additional methods:
=over 12
=item C<tkRunning>
makes Tk event loop run when waiting for user input (i.e., during
C<readline> method).
=item C<event_loop>
Registers call-backs to wait for user input (i.e., during C<readline>
method). This supersedes tkRunning.
The first call-back registered is the call back for waiting. It is
expected that the callback will call the current event loop until
there is something waiting to get on the input filehandle. The parameter
passed in is the return value of the second call back.
The second call-back registered is the call back for registration. The
input filehandle (often STDIN, but not necessarily) will be passed in.
For example, with AnyEvent:
$term->event_loop(sub {
my $data = shift;
$data->[1] = AE::cv();
$data->[1]->recv();
}, sub {
my $fh = shift;
my $data = [];
$data->[0] = AE::io($fh, 0, sub { $data->[1]->send() });
$data;
});
The second call-back is optional if the call back is registered prior to
the call to $term-E<gt>readline.
Deregistration is done in this case by calling event_loop with C<undef>
as its parameter:
$term->event_loop(undef);
This will cause the data array ref to be removed, allowing normal garbage
collection to clean it up. With AnyEvent, that will cause $data->[0] to
be cleaned up, and AnyEvent will automatically cancel the watcher at that
time. If another loop requires more than that to clean up a file watcher,
that will be up to the caller to handle.
=item C<ornaments>
makes the command line stand out by using termcap data. The argument
to C<ornaments> should be 0, 1, or a string of a form
C<"aa,bb,cc,dd">. Four components of this string should be names of
I<terminal capacities>, first two will be issued to make the prompt
standout, last two to make the input line standout.
=item C<newTTY>
takes two arguments which are input filehandle and output filehandle.
Switches to use these filehandles.
=back
One can check whether the currently loaded ReadLine package supports
these methods by checking for corresponding C<Features>.
=head1 EXPORTS
None
=head1 ENVIRONMENT
The environment variable C<PERL_RL> governs which ReadLine clone is
loaded. If the value is false, a dummy interface is used. If the value
is true, it should be tail of the name of the package to use, such as
C<Perl> or C<Gnu>.
As a special case, if the value of this variable is space-separated,
the tail might be used to disable the ornaments by setting the tail to
be C<o=0> or C<ornaments=0>. The head should be as described above, say
If the variable is not set, or if the head of space-separated list is
empty, the best available package is loaded.
export "PERL_RL=Perl o=0" # Use Perl ReadLine sans ornaments
export "PERL_RL= o=0" # Use best available ReadLine sans ornaments
(Note that processing of C<PERL_RL> for ornaments is in the discretion of the
particular used C<Term::ReadLine::*> package).

package Term::ReadKey;

=head1 NAME
Term::ReadKey - A perl module for simple terminal control
=head1 SYNOPSIS
use Term::ReadKey;
ReadMode 4; # Turn off controls keys
while (not defined ($key = ReadKey(-1))) {
# No key yet
}
print "Get key $key\n";
ReadMode 0; # Reset tty mode before exiting
=head1 DESCRIPTION
Term::ReadKey is a compiled perl module dedicated to providing simple
control over terminal driver modes (cbreak, raw, cooked, etc.,) support for
non-blocking reads, if the architecture allows, and some generalized handy
functions for working with terminals. One of the main goals is to have the
functions as portable as possible, so you can just plug in "use
Term::ReadKey" on any architecture and have a good likelihood of it working.
Version 2.30.01:
Added handling of arrows, page up/down, home/end, insert/delete keys
under Win32. These keys emit xterm-compatible sequences.
Works with Term::ReadLine::Perl.
=over 4
=item ReadMode MODE [, Filehandle]
Takes an integer argument or a string synonym (case insensitive), which
can currently be one of the following values:
INT SYNONYM DESCRIPTION
0 'restore' Restore original settings.
1 'normal' Change to what is commonly the default mode,
echo on, buffered, signals enabled, Xon/Xoff
possibly enabled, and 8-bit mode possibly disabled.
2 'noecho' Same as 1, just with echo off. Nice for
reading passwords.
3 'cbreak' Echo off, unbuffered, signals enabled, Xon/Xoff
possibly enabled, and 8-bit mode possibly enabled.
4 'raw' Echo off, unbuffered, signals disabled, Xon/Xoff
disabled, and 8-bit mode possibly disabled.
5 'ultra-raw' Echo off, unbuffered, signals disabled, Xon/Xoff
disabled, 8-bit mode enabled if parity permits,
and CR to CR/LF translation turned off.
These functions are automatically applied to the STDIN handle if no
other handle is supplied. Modes 0 and 5 have some special properties
worth mentioning: not only will mode 0 restore original settings, but it
cause the next ReadMode call to save a new set of default settings. Mode
5 is similar to mode 4, except no CR/LF translation is performed, and if
possible, parity will be disabled (only if not being used by the terminal,
however. It is no different from mode 4 under Windows.)
If you just need to read a key at a time, then modes 3 or 4 are probably
sufficient. Mode 4 is a tad more flexible, but needs a bit more work to
control. If you use ReadMode 3, then you should install a SIGINT or END
handler to reset the terminal (via ReadMode 0) if the user aborts the
program via C<^C>. (For any mode, an END handler consisting of "ReadMode 0"
is actually a good idea.)
If you are executing another program that may be changing the terminal mode,
you will either want to say
ReadMode 1; # same as ReadMode 'normal'
system('someprogram');
ReadMode 1;
which resets the settings after the program has run, or:
$somemode=1;
ReadMode 0; # same as ReadMode 'restore'
system('someprogram');
ReadMode 1;
which records any changes the program may have made, before resetting the
mode.
=item ReadKey MODE [, Filehandle]
Takes an integer argument, which can currently be one of the following
values:
0 Perform a normal read using getc
-1 Perform a non-blocked read
>0 Perform a timed read
If the filehandle is not supplied, it will default to STDIN. If there is
nothing waiting in the buffer during a non-blocked read, then undef will be
returned. In most situations, you will probably want to use C<ReadKey -1>.
I<NOTE> that if the OS does not provide any known mechanism for non-blocking
reads, then a C<ReadKey -1> can die with a fatal error. This will hopefully
not be common.
If MODE is greater then zero, then ReadKey will use it as a timeout value in
seconds (fractional seconds are allowed), and won't return C<undef> until
that time expires.
I<NOTE>, again, that some OS's may not support this timeout behaviour.
If MODE is less then zero, then this is treated as a timeout
of zero, and thus will return immediately if no character is waiting. A MODE
of zero, however, will act like a normal getc.
I<NOTE>, there are currently some limitations with this call under Windows.
It may be possible that non-blocking reads will fail when reading repeating
keys from more then one console.
=item ReadLine MODE [, Filehandle]
Takes an integer argument, which can currently be one of the following
values:
0 Perform a normal read using scalar(<FileHandle>)
-1 Perform a non-blocked read
>0 Perform a timed read
If there is nothing waiting in the buffer during a non-blocked read, then
undef will be returned.
I<NOTE>, that if the OS does not provide any known mechanism for
non-blocking reads, then a C<ReadLine 1> can die with a fatal
error. This will hopefully not be common.
I<NOTE> that a non-blocking test is only performed for the first character
in the line, not the entire line. This call will probably B<not> do what
you assume, especially with C<ReadMode> MODE values higher then 1. For
example, pressing Space and then Backspace would appear to leave you
where you started, but any timeouts would now be suspended.
B<This call is currently not available under Windows>.
=item GetTerminalSize [Filehandle]
Returns either an empty array if this operation is unsupported, or a four
element array containing: the width of the terminal in characters, the
height of the terminal in character, the width in pixels, and the height in
pixels. (The pixel size will only be valid in some environments.)
I<NOTE>, under Windows, this function must be called with an B<output>
filehandle, such as C<STDOUT>, or a handle opened to C<CONOUT$>.
=item SetTerminalSize WIDTH,HEIGHT,XPIX,YPIX [, Filehandle]
Return -1 on failure, 0 otherwise.
I<NOTE> that this terminal size is only for B<informative> value, and
changing the size via this mechanism will B<not> change the size of
the screen. For example, XTerm uses a call like this when
it resizes the screen. If any of the new measurements vary from the old, the
OS will probably send a SIGWINCH signal to anything reading that tty or pty.
B<This call does not work under Windows>.
=item GetSpeed [, Filehandle]
Returns either an empty array if the operation is unsupported, or a two
value array containing the terminal in and out speeds, in B<decimal>. E.g,
an in speed of 9600 baud and an out speed of 4800 baud would be returned as
(9600,4800). Note that currently the in and out speeds will always be
identical in some OS's.
B<No speeds are reported under Windows>.
=item GetControlChars [, Filehandle]
Returns an array containing key/value pairs suitable for a hash. The pairs
consist of a key, the name of the control character/signal, and the value
of that character, as a single character.
B<This call does nothing under Windows>.
Each key will be an entry from the following list:
DISCARD
DSUSPEND
EOF
EOL
EOL2
ERASE
ERASEWORD
INTERRUPT
KILL
MIN
QUIT
QUOTENEXT
REPRINT
START
STATUS
STOP
SUSPEND
SWITCH
TIME
Thus, the following will always return the current interrupt character,
regardless of platform.
%keys = GetControlChars;
$int = $keys{INTERRUPT};
=item SetControlChars [, Filehandle]
Takes an array containing key/value pairs, as a hash will produce. The pairs
should consist of a key that is the name of a legal control
character/signal, and the value should be either a single character, or a
number in the range 0-255. SetControlChars will die with a runtime error if
an invalid character name is passed or there is an error changing the
settings. The list of valid names is easily available via
%cchars = GetControlChars();
@cnames = keys %cchars;
