Every time a terminal object gets created, extension scripts specified via
the \f(CW\*(C`perl\*(C'\fR resource are loaded and associated with it.
.PP
Scripts are compiled in a 'use strict \*(L"vars\*(R"' and 'use utf8' environment, and
thus must be encoded as \s-1UTF\-8\s0.
.PP
Each script will only ever be loaded once, even in @@RXVT_NAME@@d, where
scripts will be shared (but not enabled) for all terminals.
.PP
You can disable the embedded perl interpreter by setting both \*(L"perl-ext\*(R"
and \*(L"perl-ext-common\*(R" resources to the empty string.
.SH "PREPACKAGED EXTENSIONS"
.IX Header "PREPACKAGED EXTENSIONS"
A number of extensions are delivered with this release. You can find them
in \fI@@RXVT_LIBDIR@@/urxvt/perl/\fR, and the documentation can be viewed
using \fIman urxvt\-<\s-1EXTENSIONNAME\s0>\fR.
.PP
You can activate them like this:

Extensions that add command line parameters or resources on their own are

.SH "API DOCUMENTATION"
.IX Header "API DOCUMENTATION"
.SS "General \s-1API\s0 Considerations"
.IX Subsection "General API Considerations"
All objects (such as terminals, time watchers etc.) are typical
reference-to-hash objects. The hash can be used to store anything you
like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
\&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
modified).
.PP
When objects are destroyed on the \*(C+ side, the perl object hashes are
emptied, so its best to store related objects such as time watchers and
the like inside the terminal object so they get destroyed as soon as the
terminal is destroyed.
.PP
Argument names also often indicate the type of a parameter. Here are some
hints on what they mean:
.ie n .IP "$text" 4
.el .IP "\f(CW$text\fR" 4
.IX Item "$text"
Rxvt-unicode's special way of encoding text, where one \*(L"unicode\*(R" character
always represents one screen cell. See ROW_t for a discussion of this format.
.ie n .IP "$string" 4
.el .IP "\f(CW$string\fR" 4
.IX Item "$string"
A perl text string, with an emphasis on \fItext\fR. It can store all unicode
characters and is to be distinguished with text encoded in a specific
encoding (often locale-specific) and binary data.
.ie n .IP "$octets" 4
.el .IP "\f(CW$octets\fR" 4
.IX Item "$octets"
Either binary data or \- more common \- a text string encoded in a
locale-specific way.
.ie n .IP "$keysym" 4
.el .IP "\f(CW$keysym\fR" 4
.IX Item "$keysym"
an integer that is a valid X11 keysym code. You can convert a string
into a keysym and viceversa by using \f(CW\*(C`XStringToKeysym\*(C'\fR and
\&\f(CW\*(C`XKeysymToString\*(C'\fR.
.SS "Extension Objects"
.IX Subsection "Extension Objects"
Every perl extension is a perl class. A separate perl object is created
for each terminal, and each terminal has its own set of extension objects,
which are passed as the first parameter to hooks. So extensions can use
their \f(CW$self\fR object without having to think about clashes with other
extensions or other terminals, with the exception of methods and members
that begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for
internal use.
.PP
Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
\&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
.PP
Additional methods only supported for extension objects are described in
the \f(CW\*(C`urxvt::extension\*(C'\fR section below.
.SS "Hooks"
.IX Subsection "Hooks"
The following subroutines can be declared in extension files, and will be
called whenever the relevant event happens.
.PP
The first argument passed to them is an extension object as described in
the in the \f(CW\*(C`Extension Objects\*(C'\fR section.
.PP
\&\fBAll\fR of these hooks must return a boolean value. If any of the called
hooks returns true, then the event counts as being \fIconsumed\fR, and the
relevant action might not be carried out by the \*(C+ code.
.PP
\&\fIWhen in doubt, return a false value (preferably \f(CI\*(C`()\*(C'\fI).\fR
.ie n .IP "on_init $term" 4
.el .IP "on_init \f(CW$term\fR" 4
.IX Item "on_init $term"
Called after a new terminal object has been initialized, but before
windows are created or the command gets run. Most methods are unsafe to
call or deliver senseless data, as terminal size and other characteristics
have not yet been determined. You can safely query and change resources
and options, though. For many purposes the \f(CW\*(C`on_start\*(C'\fR hook is a better
place.
.ie n .IP "on_start $term" 4
.el .IP "on_start \f(CW$term\fR" 4
.IX Item "on_start $term"
Called at the very end of initialisation of a new terminal, just before
trying to map (display) the toplevel and returning to the main loop.
.ie n .IP "on_destroy $term" 4
.el .IP "on_destroy \f(CW$term\fR" 4
.IX Item "on_destroy $term"
Called whenever something tries to destroy terminal, when the terminal is
still fully functional (not for long, though).
.ie n .IP "on_reset $term" 4
.el .IP "on_reset \f(CW$term\fR" 4
.IX Item "on_reset $term"
Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or
control sequences. Here is where you can react on changes to size-related
variables.
.ie n .IP "on_child_start $term, $pid" 4
.el .IP "on_child_start \f(CW$term\fR, \f(CW$pid\fR" 4
.IX Item "on_child_start $term, $pid"
Called just after the child process has been \f(CW\*(C`fork\*(C'\fRed.
.ie n .IP "on_child_exit $term, $status" 4
.el .IP "on_child_exit \f(CW$term\fR, \f(CW$status\fR" 4
.IX Item "on_child_exit $term, $status"
Called just after the child process has exited. \f(CW$status\fR is the status
from \f(CW\*(C`waitpid\*(C'\fR.
.ie n .IP "on_sel_make $term, $eventtime" 4
.el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4
.IX Item "on_sel_make $term, $eventtime"
Called whenever a selection has been made by the user, but before the
selection text is copied, so changes to the beginning, end or type of the
selection will be honored.
.Sp
Returning a true value aborts selection making by urxvt, in which case you
have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR.
.ie n .IP "on_sel_grab $term, $eventtime" 4
.el .IP "on_sel_grab \f(CW$term\fR, \f(CW$eventtime\fR" 4
.IX Item "on_sel_grab $term, $eventtime"
Called whenever a selection has been copied, but before the selection is
requested from the server.  The selection text can be queried and changed
by calling \f(CW\*(C`$term\->selection\*(C'\fR.
.Sp
Returning a true value aborts selection grabbing. It will still be highlighted.
.ie n .IP "on_sel_extend $term" 4
.el .IP "on_sel_extend \f(CW$term\fR" 4
.IX Item "on_sel_extend $term"
Called whenever the user tries to extend the selection (e.g. with a double
click) and is either supposed to return false (normal operation), or
should extend the selection itself and return true to suppress the built-in
processing. This can happen multiple times, as long as the callback
returns true, it will be called on every further click by the user and is
supposed to enlarge the selection more and more, if possible.
.Sp
See the \fIselection\fR example extension.
.ie n .IP "on_view_change $term, $offset" 4
.el .IP "on_view_change \f(CW$term\fR, \f(CW$offset\fR" 4
.IX Item "on_view_change $term, $offset"
Called whenever the view offset changes, i.e. the user or program
scrolls. Offset \f(CW0\fR means display the normal terminal, positive values
show this many lines of scrollback.
.ie n .IP "on_scroll_back $term, $lines, $saved" 4
.el .IP "on_scroll_back \f(CW$term\fR, \f(CW$lines\fR, \f(CW$saved\fR" 4
.IX Item "on_scroll_back $term, $lines, $saved"
Called whenever lines scroll out of the terminal area into the scrollback
buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger
than the scroll back buffer or the terminal.
.Sp
It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1,
\&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total
number of lines that will be in the scrollback buffer.
.ie n .IP "on_osc_seq $term, $op, $args, $resp" 4
.el .IP "on_osc_seq \f(CW$term\fR, \f(CW$op\fR, \f(CW$args\fR, \f(CW$resp\fR" 4
.IX Item "on_osc_seq $term, $op, $args, $resp"
Called on every \s-1OSC\s0 sequence and can be used to suppress it or modify its
behaviour. The default should be to return an empty list. A true value
suppresses execution of the request completely. Make sure you don't get
confused by recursive invocations when you output an \s-1OSC\s0 sequence within
this callback.
.Sp
\&\f(CW\*(C`on_osc_seq_perl\*(C'\fR should be used for new behaviour.
.ie n .IP "on_osc_seq_perl $term, $args, $resp" 4
.el .IP "on_osc_seq_perl \f(CW$term\fR, \f(CW$args\fR, \f(CW$resp\fR" 4
.IX Item "on_osc_seq_perl $term, $args, $resp"
Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 =
operating system command) is processed. Cursor position and other state
information is up-to-date when this happens. For interoperability, the
string should start with the extension name (sans \-osc) and a semicolon,
to distinguish it from commands for other extensions, and this might be
enforced in the future.
.Sp
For example, \f(CW\*(C`overlay\-osc\*(C'\fR uses this:
.Sp
.Vb 2
\&   sub on_osc_seq_perl {
\&      my ($self, $osc, $resp) = @_;
\&
\&      return unless $osc =~ s/^overlay;//;
\&
\&      ... process remaining $osc string
\&   }
.Ve
.Sp
Be careful not ever to trust (in a security sense) the data you receive,
as its source can not easily be controlled (e\-mail content, messages from
other users on the same system etc.).
.Sp
For responses, \f(CW$resp\fR contains the end-of-args separator used by the
sender.
.ie n .IP "on_add_lines $term, $string" 4
.el .IP "on_add_lines \f(CW$term\fR, \f(CW$string\fR" 4
.IX Item "on_add_lines $term, $string"
Called whenever text is about to be output, with the text as argument. You
can filter/change and output the text yourself by returning a true value
and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this
might be very slow, however, as your hook is called for \fBall\fR text being
output.
.ie n .IP "on_tt_write $term, $octets" 4
.el .IP "on_tt_write \f(CW$term\fR, \f(CW$octets\fR" 4
.IX Item "on_tt_write $term, $octets"
Called whenever some data is written to the tty/pty and can be used to
suppress or filter tty input.
.ie n .IP "on_tt_paste $term, $octets" 4
.el .IP "on_tt_paste \f(CW$term\fR, \f(CW$octets\fR" 4
.IX Item "on_tt_paste $term, $octets"
Called whenever text is about to be pasted, with the text as argument. You
can filter/change and paste the text yourself by returning a true value
and calling \f(CW\*(C`$term\->tt_paste\*(C'\fR yourself. \f(CW$octets\fR is
locale-encoded.
.ie n .IP "on_line_update $term, $row" 4
.el .IP "on_line_update \f(CW$term\fR, \f(CW$row\fR" 4
.IX Item "on_line_update $term, $row"
Called whenever a line was updated or changed. Can be used to filter
screen output (e.g. underline urls or other useless stuff). Only lines
that are being shown will be filtered, and, due to performance reasons,
not always immediately.
.Sp
The row number is always the topmost row of the line if the line spans
multiple rows.
.Sp
Please note that, if you change the line, then the hook might get called
later with the already-modified line (e.g. if unrelated parts change), so
you cannot just toggle rendition bits, but only set them.
.ie n .IP "on_refresh_begin $term" 4
.el .IP "on_refresh_begin \f(CW$term\fR" 4
.IX Item "on_refresh_begin $term"
Called just before the screen gets redrawn. Can be used for overlay or
similar effects by modifying the terminal contents in refresh_begin, and
restoring them in refresh_end. The built-in overlay and selection display
code is run after this hook, and takes precedence.
.ie n .IP "on_refresh_end $term" 4
.el .IP "on_refresh_end \f(CW$term\fR" 4
.IX Item "on_refresh_end $term"
Called just after the screen gets redrawn. See \f(CW\*(C`on_refresh_begin\*(C'\fR.
.ie n .IP "on_user_command $term, $string" 4
.el .IP "on_user_command \f(CW$term\fR, \f(CW$string\fR" 4
.IX Item "on_user_command $term, $string"
Called whenever a user-configured event is being activated (e.g. via
a \f(CW\*(C`perl:string\*(C'\fR action bound to a key, see description of the \fBkeysym\fR
resource in the @@RXVT_NAME@@(1) manpage).
.Sp
The event is simply the action string. This interface is assumed to change
slightly in the future.
.ie n .IP "on_register_command $term, $keysym, $modifiermask, $string" 4
.el .IP "on_register_command \f(CW$term\fR, \f(CW$keysym\fR, \f(CW$modifiermask\fR, \f(CW$string\fR" 4
.IX Item "on_register_command $term, $keysym, $modifiermask, $string"
Called after parsing a keysym resource but before registering the
associated binding. If this hook returns \s-1TRUE\s0 the binding is not
registered. It can be used to modify a binding by calling
\&\f(CW\*(C`register_command\*(C'\fR.
.ie n .IP "on_resize_all_windows $term, $new_width, $new_height" 4
.el .IP "on_resize_all_windows \f(CW$term\fR, \f(CW$new_width\fR, \f(CW$new_height\fR" 4
.IX Item "on_resize_all_windows $term, $new_width, $new_height"
Called just after the new window size has been calculated, but before
windows are actually being resized or hints are being set. If this hook
returns \s-1TRUE\s0, setting of the window hints is being skipped.
.ie n .IP "on_x_event $term, $event" 4
.el .IP "on_x_event \f(CW$term\fR, \f(CW$event\fR" 4
.IX Item "on_x_event $term, $event"
Called on every X event received on the vt window (and possibly other
windows). Should only be used as a last resort. Most event structure
members are not passed.
.ie n .IP "on_root_event $term, $event" 4
.el .IP "on_root_event \f(CW$term\fR, \f(CW$event\fR" 4

.PP
You can use these objects, which are passed to all callbacks to store any
state related to the terminal and extension instance.

The methods (And data members) documented below can be called on extension
objects, in addition to call methods documented for the <urxvt::term>
class.

.IX Item "$self->enable ($hook_name => $cb[, $hook_name => $cb..])"
Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
this extension, replacing any previous hook. This is useful when you want
to overwrite time-critical hooks only temporarily.
.Sp
To install additional callbacks for the same hook, you can use the \f(CW\*(C`on\*(C'\fR
method of the \f(CW\*(C`urxvt::term\*(C'\fR class.
.ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
.el .IP "\f(CW$self\fR\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4

.IX Item "$guard = $self->on ($hook_name => $cb[, $hook_name => $cb..])"
Similar to the \f(CW\*(C`enable\*(C'\fR enable, but installs additional callbacks for
the given hook(s) (that is, it doesn't replace existing callbacks), and
returns a guard object. When the guard object is destroyed the callbacks
are disabled again.

The sole purpose of this class is to deliver an interface to the

further programming. The only exception is that you cannot wait on
condition variables, but non-blocking condvar use is ok.

the non-blocking variant should work.

.IX Item "$term = new urxvt::term $envhashref, $rxvtname, [arg...]"
Creates a new terminal, very similar as if you had started it with system
\&\f(CW\*(C`$rxvtname, arg...\*(C'\fR. \f(CW$envhashref\fR must be a reference to a \f(CW%ENV\fR\-like
hash which defines the environment of the new terminal.
.Sp
Croaks (and probably outputs an error message) if the new instance
couldn't be created.  Returns \f(CW\*(C`undef\*(C'\fR if the new instance didn't
initialise perl, and the terminal object otherwise. The \f(CW\*(C`init\*(C'\fR and
\&\f(CW\*(C`start\*(C'\fR hooks will be called before this call returns, and are free to
refer to global data (which is race free).
.ie n .IP "$term\->destroy" 4
.el .IP "\f(CW$term\fR\->destroy" 4

Destroy the terminal object (close the window, free resources

.el .IP "\f(CW$term\fR\->exec_async ($cmd[, \f(CW@args\fR])" 4
.IX Item "$term->exec_async ($cmd[, @args])"
Works like the combination of the \f(CW\*(C`fork\*(C'\fR/\f(CW\*(C`exec\*(C'\fR builtins, which executes
(\*(L"starts\*(R") programs in the background. This function takes care of setting
the user environment before exec'ing the command (e.g. \f(CW\*(C`PATH\*(C'\fR) and should
be preferred over explicit calls to \f(CW\*(C`exec\*(C'\fR or \f(CW\*(C`system\*(C'\fR.

optionally sets a new value. Setting values is most useful in the \f(CW\*(C`init\*(C'\fR
hook. Unset resources are returned and accepted as \f(CW\*(C`undef\*(C'\fR.

The new value must be properly encoded to a suitable character encoding
before passing it to this method. Similarly, the returned value may need
to be converted from the used encoding to text.

.el .IP "\f(CW$value\fR = \f(CW$term\fR\->x_resource ($pattern)" 4
.IX Item "$value = $term->x_resource ($pattern)"
Returns the X\-Resource for the given pattern, excluding the program or
class name, i.e.  \f(CW\*(C`$term\->x_resource ("boldFont")\*(C'\fR should return the
same value as used by this instance of rxvt-unicode. Returns \f(CW\*(C`undef\*(C'\fR if no
resource with that pattern exists.
.Sp
Extensions that define extra resource or command line arguments also need
to call this method to access their values.
.Sp
If the method is called on an extension object (basically, from an
extension), then the special prefix \f(CW\*(C`%.\*(C'\fR will be replaced by the name of
the extension and a dot, and the lone string \f(CW\*(C`%\*(C'\fR will be replaced by the
extension name itself. This makes it possible to code extensions so you
can rename them and get a new set of commandline switches and resources
without having to change the actual code.
.Sp
This method should only be called during the \f(CW\*(C`on_start\*(C'\fR hook, as there is
only one resource database per display, and later invocations might return
the wrong resources.
.ie n .IP "$value = $term\->x_resource_boolean ($pattern)" 4
.el .IP "\f(CW$value\fR = \f(CW$term\fR\->x_resource_boolean ($pattern)" 4
.IX Item "$value = $term->x_resource_boolean ($pattern)"
Like \f(CW\*(C`x_resource\*(C'\fR, above, but interprets the string value as a boolean
and returns \f(CW1\fR for true values, \f(CW0\fR for false values and \f(CW\*(C`undef\*(C'\fR if
the resource or option isn't specified.
.Sp
You should always use this method to parse boolean resources.

.IX Item "$term->register_command ($keysym, $modifiermask, $string)"
Adds a key binding. This is a lower level api compared to
\&\f(CW\*(C`parse_keysym\*(C'\fR, as it expects a parsed key description, and can be
used only inside either the \f(CW\*(C`on_init\*(C'\fR hook, to add a binding, or the
