On startup, rxvt will scan /opt/rxvt/lib/urxvt/perl-ext/
-for files and will load them. Everytime a terminal object gets created,
-the directory specified by the perl-lib resource will be additionally
-scanned.
Everytime a terminal object gets created, extension scripts specified via
+the perl resource are loaded and associated with it.
Scripts are compiled in a 'use strict' and 'use utf8' environment, and +thus must be encoded as UTF-8.
Each script will only ever be loaded once, even in rxvtd, where -scripts will be shared for all terminals.
-Hooks in scripts specified by perl-lib will only be called for the

+
+This section describes the extensions delivered with this release. You can +find them in /opt/rxvt/lib/urxvt/perl/.
+You can activate them like this:
++ rxvt -pe <extensionname>+
Or by adding them to the resource for extensions loaded by default:
++ URxvt.perl-ext-common: default,automove-background,selection-autotransform+
(More) intelligent selection. This extension tries to be more intelligent
+when the user extends selections (double-click and further clicks). Right
+now, it tries to select words, urls and complete shell-quoted
+arguments, which is very convenient, too, if your ls supports
+--quoting-style=shell.
A double-click usually selects the word under the cursor, further clicks +will enlarge the selection.
+The selection works by trying to match a number of regexes and displaying +them in increasing order of length. You can add your own regexes by +specifying resources of the form:
++ URxvt.selection.pattern-0: perl-regex + URxvt.selection.pattern-1: perl-regex + ...+
The index number (0, 1...) must not have any holes, and each regex must +contain at least one pair of capturing parentheses, which will be used for +the match. For example, the followign adds a regex that matches everything +between two vertical bars:
++ URxvt.selection.pattern-0: \\|([^|]+)\\|+
Another example: Programs I use often output ``absolute path: '' at the +beginning of a line when they process multiple files. The following +pattern matches the filename (note, there is a single space at the very +end):
++ URxvt.selection.pattern-0: ^(/[^:]+):\+
You can look at the source of the selection extension to see more +interesting uses, such as parsing a line from beginning to end.
+This extension also offers following bindable keyboard commands:
+Rot-13 the selection when activated. Used via keyboard trigger:
++ URxvt.keysym.C-M-r: perl:selection:rot13+
Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at +runtime.
+Other extensions can extend this popup menu by pushing a code reference
+onto @{ $term-{option_popup_hook} }>, which gets called whenever the
+popup is being displayed.
It's sole argument is the popup menu, which can be modified. It should +either return nothing or a string, the initial boolean value and a code +reference. The string will be used as button text and the code reference +will be called when the toggle changes, with the new boolean value as +first argument.
+The following will add an entry myoption that changes
+$self-{myoption}>:
+ push @{ $self->{term}{option_popup_hook} }, sub {
+ ("my option" => $myoption, sub { $self->{myoption} = $_[0] })
+ };
+Binds a popup menu to Ctrl-Button3 that lets you convert the selection +text into various other formats/action (such as uri unescaping, perl +evaluation, web-browser starting etc.), depending on content.
+Other extensions can extend this popup menu by pushing a code reference
+onto @{ $term-{selection_popup_hook} }>, which gets called whenever the
+popup is being displayed.
It's sole argument is the popup menu, which can be modified. The selection
+is in $_, which can be used to decide wether to add something or not.
+It should either return nothing or a string and a code reference. The
+string will be used as button text and the code reference will be called
+when the button gets activated and should transform $_.
The following will add an entry a to b that transforms all as in
+the selection to bs, but only if the selection currently contains any
+as:
+ push @{ $self->{term}{selection_popup_hook} }, sub {
+ /a/ ? ("a to be" => sub { s/a/b/g }
+ : ()
+ };
+Adds regex search functionality to the scrollback buffer, triggered
+by a hotkey (default: M-s). While in search mode, normal terminal
+input/output is suspended and a regex is displayed at the bottom of the
+screen.
Inputting characters appends them to the regex and continues incremental
+search. BackSpace removes a character from the regex, Up and Down
+search upwards/downwards in the scrollback buffer, End jumps to the
+bottom. Escape leaves search mode and returns to the point where search
+was started, while Enter or Return stay at the current position and
+additionally stores the first match in the current line into the primary
+selection.
The regex defaults to ``(?i)'', resulting in a case-insensitive search. To
+get a case-sensitive search you can delete this prefix using BackSpace
+or simply use an uppercase character which removes the ``(?i)'' prefix.
See perlre for more info about perl regular expression syntax.
+A support package that tries to make editing with readline easier. At +the moment, it reacts to clicking shift-left mouse button by trying to +move the text cursor to this position. It does so by generating as many +cursor-left or cursor-right keypresses as required (the this only works +for programs that correctly support wide characters).
+To avoid too many false positives, this is only done when:
+The normal selection mechanism isn't disabled, so quick successive clicks +might interfere with selection creation in harmless ways.
+This selection allows you to do automatic transforms on a selection +whenever a selection is made.
+It works by specifying perl snippets (most useful is a single s///
+operator) that modify $_ as resources:
+ URxvt.selection-autotransform.0: transform + URxvt.selection-autotransform.1: transform + ...+
For example, the following will transform selections of the form
+filename:number, often seen in compiler messages, into vi +$filename
+$word:
+ URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/+
And this example matches the same,but replaces it with vi-commands you can +paste directly into your (vi :) editor:
++ URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/+
Of course, this can be modified to suit your needs and your editor :)
+To expand the example above to typical perl error messages (``XXX at +FILENAME line YYY.''), you need a slightly more elaborate solution:
++ URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) + URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/+
The first line tells the selection code to treat the unchanging part of +every error message as a selection pattern, and the second line transforms +the message into vi commands to load the file.
+This transforms the terminal into a tabbar with additional terminals, that +is, it implements what is commonly refered to as ``tabbed terminal''. The topmost line +displays a ``[NEW]'' button, which, when clicked, will add a new tab, followed by one +button per tab.
+Clicking a button will activate that tab. Pressing Shift-Left and +Shift-Right will switch to the tab left or right of the current one, +while Shift-Down creates a new tab.
+The tabbar itself can be configured similarly to a normal terminal, but
+with a resource class of URxvt.tabbed. In addition, it supports the
+following four resources (shown with defaults):
+ URxvt.tabbed.tabbar-fg: <colour-index, default 3> + URxvt.tabbed.tabbar-bg: <colour-index, default 0> + URxvt.tabbed.tab-fg: <colour-index, default 0> + URxvt.tabbed.tab-bg: <colour-index, default 1>+
See COLOR AND GRAPHICS in the rxvt(1) manpage for valid
+indices.
Uses per-line display filtering (on_line_update) to underline urls and
+make them clickable. When middle-clicked, the program specified in the
+resource urlLauncher (default x-www-browser) will be started with
+the URL as first argument.
This (experimental) perl extension implements OnTheSpot editing. It does +not work perfectly, and some input methods don't seem to work well with +OnTheSpot editing in general, but it seems to work at leats for SCIM and +kinput2.
+You enable it by specifying this extension and a preedit style of
+OnTheSpot, i.e.:
+ rxvt -pt OnTheSpot -pe xim-onthespot+
A very primitive quake-console-like extension. It was inspired by a
+description of how the programs kuake and yakuake work: Whenever the
+user presses a global accelerator key (by default F10), the terminal
+will show or hide itself. Another press of the accelerator key will hide
+or show it again.
Initially, the window will not be shown when using this extension.
+This is useful if you need a single terminal thats not using any desktop +space most of the time but is quickly available at the press of a key.
+The accelerator key is grabbed regardless of any modifers, so this +extension will actually grab a physical key just for this function.
+If you want a quake-like animation, tell your window manager to do so +(fvwm can do it).
+This is basically a very small extension that dynamically changes the +background pixmap offset to the window position, in effect creating the +same effect as pseudo transparency with a custom pixmap. No scaling is +supported in this mode. Exmaple:
++ rxvt -pixmap background.xpm -pe automove-background+
A not very useful example of filtering all text output to the terminal +by replacing all line-drawing characters (U+2500 .. U+259F) by a +similar-looking ascii character.
+Displays a digital clock using the built-in overlay.
+Somewhat of a misnomer, this extension adds two menu entries to the +selection popup that allows one ti run external commands to store the +selection somewhere and fetch it again.
+We use it to implement a ``distributed selection mechanism'', which just +means that one command uploads the file to a remote server, and another +reads it.
+The commands can be set using the URxvt.remote-selection.store and
+URxvt.remote-selection.fetch resources. The first should read the
+selection to store from STDIN (always in UTF-8), the second should provide
+the selection data on STDOUT (also in UTF-8).
The defaults (which are likely useless to you) use rsh and cat:
++ URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection' + URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'+
This is a little rarely useful extension that Uploads the selection as +textfile to a remote site (or does other things). (The implementation is +not currently secure for use in a multiuser environment as it writes to +/tmp directly.).
+It listens to the selection-pastebin:remote-pastebin keyboard command,
+i.e.
+ URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin+
Pressing this combination runs a command with % replaced by the name of
+the textfile. This command can be set via a resource:
+ URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.+
And the default is likely not useful to anybody but the few people around +here :)
+The name of the textfile is the hex encoded md5 sum of the selection, so +the same content should lead to the same filename.
+After a successful upload the selection will be replaced by the text given
+in the selection-pastebin-url resource (again, the % is the placeholder
+for the filename):
+ URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%+
Displays a very simple digital clock in the upper right corner of the +window. Illustrates overwriting the refresh callbacks to create your own +overlays or changes.

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 _ptr or
-_hook) are reserved for internal uses and must not be accessed or
+_hook) are reserved for internal uses and MUST NOT be accessed or
modified).
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.
+Argument names also often indicate the type of a parameter. Here are some +hints on what they mean:
+Rxvt-unicodes special way of encoding text, where one ``unicode'' character +always represents one screen cell. See ROW_t for a discussion of this format.
+A perl text string, with an emphasis on text. It can store all unicode +characters and is to be distinguished with text encoded in a specific +encoding (often locale-specific) and binary data.
+Either binary data or - more common - a text string encoded in a +locale-specific way.
++
+Every perl extension is a perl class. A separate perl object is created
+for each terminal and each extension and passed as the first parameter to
+hooks. So extensions can use their $self object without having to think
+about other extensions, with the exception of methods and members that
+begin with an underscore character _: these are reserved for internal
+use.
Although it isn't a urxvt::term object, you can call all methods of the
+urxvt::term class on this object.
It has the following methods and data members:
+Returns the urxvt::term object associated with this instance of the
+extension. This member must not be changed in any way.

The following subroutines can be declared in loaded scripts, and will be called -whenever the relevant event happens.

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

+by calling $term->selection.
Returning a true value aborts selection grabbing. It will still be hilighted.
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 itelf 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.

It is called before lines are scrolled out (so rows 0 .. min ($lines - 1,
$nrow - 1) represent the lines to be scrolled out). $saved is the total
number of lines that will be in the scrollback buffer.
Called on every OSC 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 osc sequence within +this callback.

+on_osc_seq_perl should be used for new behaviour.
Called whenever the ESC ] 777 ; string ST command sequence (OSC = +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 and a colon, to distinguish +it from commands for other extensions, and this might be enforced in the +future.
+Be careful not ever to trust (in a security sense) the data you receive, +as its source can not easily be controleld (e-mail content, messages from +other users on the same system etc.).
+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 $term->scr_add_lines yourself. Please note that this
+might be very slow, however, as your hook is called for all text being
+output.
Called whenever some data is written to the tty/pty and can be used to +suppress or filter tty input.
+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.
+The row number is always the topmost row of the line if the line spans +multiple rows.
+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.
+Called just before the screen gets redrawn. Can be used for overlay or similar effects by modify terminal contents in refresh_begin, and restoring them in refresh_end.

+resource in the rxvt(1) manpage).
on_refresh_begin.
+The event is simply the action string. This interface is assumed to change +slightly in the future.
Called just after the new window size has been calculcated, but before +windows are actually being resized or hints are being set. If this hook +returns TRUE, setting of the window hints is being skipped.
+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.
+Like on_x_event, but is called for events on the root window.
Called whenever the window gets the keyboard focus, before rxvt-unicode +does focus in processing.
+Called wheneever the window loses keyboard focus, before rxvt-unicode does +focus out processing.
+Called whenever the corresponding X event is received for the terminal If +the hook returns true, then the even will be ignored by rxvt-unicode.
+The event is a hash with most values as named by Xlib (see the XEvent
+manpage), with the additional members row and col, which are the
+(real, not screen-based) row and column under the mouse cursor.
on_key_press additionally receives the string rxvt-unicode would
+output, if any, in locale-specific encoding.

+urxvt PackageThe rxvt-unicode library directory, where, among other things, the perl +modules and scripts are stored.
+The resource class and name rxvt-unicode uses to look up X resources.
+The basename of the installed binaries, usually urxvt.
The current terminal. This variable stores the current urxvt::term
+object, whenever a callback/hook is executing.
All coderefs in this array will be called as methods of the next newly
+created urxvt::term object (during the on_init phase). The array
+gets cleared before the codereferences that were in it are being executed,
+so coderefs can push themselves onto it again if they so desire.
This complements to the perl-eval commandline option, but gets executed +first.
+Works similar to @TERM_INIT, but contains perl package/class names, which
+get registered as normal extensions after calling the hooks in @TERM_INIT
+but before other extensions. Gets cleared just like @TERM_INIT.

+that calls this function.
Using this function has the advantage that its output ends up in the correct place, e.g. on stderr of the connecting urxvtc client.
Messages have a size limit of 1023 bytes currently.
Returns all urxvt::term objects that exist in this process, regardless of +wether they are started, being destroyed etc., so be careful. Only term +objects that have perl extensions attached will be returned (because there +is no urxvt::term objet associated with others).
+Returns the ``current time'' (as per the event loop).
+Various constants for use in X calls and event processing.
++
+Rendition bitsets contain information about colour, font, font styles and +similar information for each screen cell.
+The following ``macros'' deal with changes in rendition sets. You should +never just create a bitset, you should always modify an existing one, +as they contain important information required for correct operation of +rxvt-unicode.
+Returns the default rendition, as used when the terminal is starting up or +being reset. Useful as a base to start when creating renditions.
+Return the rendition mask used for overlays by default.
+Return the bit that enabled bold, italic, blink, reverse-video and +underline, respectively. To enable such a style, just logically OR it into +the bitset.
+Return the foreground/background colour index, respectively.
+Replace the foreground/background colour in the rendition mask with the +specified one.
+Return the ``custom'' value: Every rendition has 5 bits for use by +extensions. They can be set and changed as you like and are initially +zero.
+Change the custom value.
++
+urxvt::anyevent ClassThe sole purpose of this class is to deliver an interface to the
+AnyEvent module - any module using it will work inside urxvt without
+further programming. The only exception is that you cannot wait on
+condition variables, but non-blocking condvar use is ok. What this means
+is that you cannot use blocking APIs, but the non-blocking variant should
+work.
urxvt::term ClassCreates a new terminal, very similar as if you had started it with system
+$rxvtname, arg.... $envhashref must be a reference to a %ENV-like
+hash which defines the environment of the new terminal.
Croaks (and probably outputs an error message) if the new instance
+couldn't be created. Returns undef if the new instance didn't
+initialise perl, and the terminal object otherwise. The init and
+start hooks will be called before this call returns, and are free to
+refer to global data (which is race free).
Destroy the terminal object (close the window, free resources +etc.). Please note that rxvt will not exit as long as any event +watchers (timers, io watchers) are still active.
+Works like the combination of the fork/exec builtins, which executes
+(``starts'') programs in the background. This function takes care of setting
+the user environment before exec'ing the command (e.g. PATH) and should
+be preferred over explicit calls to exec or system.
Returns the pid of the subprocess or undef on error.
Returns true if the option specified by $optval is enabled, and
+optionally change it. All option values are stored by name in the hash
+%urxvt::OPTION. Options not enabled in this binary are not in the hash.

+Return the current coordinates of the text cursor position and optionally +set it (which is usually bad as applications don't expect that).
Return the current values of the selection mark, begin or end positions, +and optionally set them to new values.
Tries to make a selection as set by selection_beg and
+selection_end. If $rectangular is true (default: false), a
+rectangular selection will be made. This is the prefered function to make
+a selection.
Try to request the primary selection text from the server (for example, as
+set by the next method). No visual feedback will be given. This function
+is mostly useful from within on_sel_grab hooks.
Return the current selection text and optionally replace it by $newtext.
Create a simple multi-line overlay box. See the next method for details.
+Create a new (empty) overlay at the given position with the given
+width/height. $rstyle defines the initial rendition style
+(default: OVERLAY_RSTYLE).
If $border is 2 (default), then a decorative border will be put
+around the box.
If either $x or $y is negative, then this is counted from the
+right/bottom side, respectively.
This method returns an urxvt::overlay object. The overlay will be visible +as long as the perl object is referenced.
$data to the tty (i.e. as program input). To
-pass characters instead of octets, you should convetr you strings first to

+The methods currently supported on urxvt::overlay objects are:
Similar to $term->ROW_t and $term->ROW_r in that it puts
+text in rxvt-unicode's special encoding and an array of rendition values
+at a specific position inside the overlay.
If visible, hide the overlay, but do not destroy it.
+If hidden, display the overlay again.
+Creates a new urxvt::popup object that implements a popup menu. The
+$event must be the event causing the menu to pop up (a button event,
+currently).
Returns the number of screen-cells this string would need. Correctly +accounts for wide and combining characters.
+Convert the given text string into the corresponding locale encoding.
+Convert the given locale-encoded octets into a perl string.
+XORs the rendition values in the given span with the provided value
+(default: RS_RVid), which MUST NOT contain font styles. Useful in
+refresh hooks to provide effects similar to the selection.
Similar to scr_xor_span, but xors a rectangle instead. Trailing
+whitespace will additionally be xored with the $rstyle2, which defaults
+to RS_RVid | RS_Uline, which removes reverse video again and underlines
+it instead. Both styles MUST NOT contain font styles.
Ring the bell!
+Write the given text string to the screen, as if output by the application +running inside the terminal. It may not contain command sequences (escape +codes), but is free to use line feeds, carriage returns and tabs. The +string is a normal text string, not in locale-dependent encoding.
+Normally its not a good idea to use this function, as programs might be
+confused by changes in cursor position or scrolling. Its useful inside a
+on_add_lines hook, though.
Switch to given screen - 0 primary, 1 secondary.
+Similar to scr_add_lines, but the argument must be in the
+locale-specific encoding of the terminal and can contain command sequences
+(escape codes) that will be interpreted.
Write the octets given in $data to the tty (i.e. as program input). To
+pass characters instead of octets, you should convert your strings first
+to the locale-specific encoding using $term->locale_encode.
Replaces the event mask of the pty watcher by the given event mask. Can
+be used to suppress input and output handling to the pty/tty. See the
+description of urxvt::timer->events. Make sure to always restore
+the previous value.
Returns the master file descriptor for the pty in use, or -1 if no pty
+is used.
Return the window id of the toplevel window.
+Return the window id of the terminal window.
+Adds the specified events to the vt event mask. Useful e.g. when you want +to receive pointer events all the times:
++ $term->vt_emask_add (urxvt::PointerMotionMask);+
Deliver various fake events to to terminal.
+Return various integers describing terminal characteristics.
+Return the DISPLAY used by rxvt-unicode.
+Returns the LC_CTYPE category string used by this rxvt-unicode.
+Returns a copy of the environment in effect for the terminal as a hashref
+similar to \%ENV.
Returns the environment as array of strings of the form VAR=VALUE.
Return the argument vector as this terminal, similar to @ARGV, but +includes the program name as first element.
+Return the modifier masks corresponding to the ``ISO Level 3 Shift'' (often +AltGr), the meta key (often Alt) and the num lock key, if applicable.
+Returns the currently displayed screen (0 primary, 1 secondary).
+Returns wether the cursor is currently hidden or not.
+Returns the row number of the topmost displayed line. Maximum value is
+0, which displays the normal terminal contents. Lower values scroll
+this many lines into the scrollback buffer.
Requests a screen refresh. At the next opportunity, rxvt-unicode will +compare the on-screen display with its stored representation. If they +differ, it redraws the differences.
+Used after changing terminal contents to display them.
+Returns the text of the entire row with number $row_number. Row 0
+is the topmost terminal line, row $term->$ncol-1 is the bottommost
+terminal line. The scrollback buffer starts at line -1 and extends to
+line -$term->nsaved. Nothing will be returned if a nonexistent line
+is requested.
If $new_text is specified, it will replace characters in the current
+line, starting at column $start_col (default 0), which is useful
+to replace only parts of a line. The font index in the rendition will
+automatically be updated.
$text is in a special encoding: tabs and wide characters that use more
+than one cell when displayed are padded with $urxvt::NOCHAR (chr 65535)
+characters. Characters with combining characters and other characters that
+do not fit into the normal tetx encoding will be replaced with characters
+in the private use area.
You have to obey this encoding when changing text. The advantage is
+that substr and similar functions work on screen cells and not on
+characters.
The methods $term->special_encode and $term->special_decode
+can be used to convert normal strings into this encoding and vice versa.
Like $term->ROW_t, but returns an arrayref with rendition
+bitsets. Rendition bitsets contain information about colour, font, font
+styles and similar information. See also $term->ROW_t.
When setting rendition, the font mask will be ignored.
+See the section on RENDITION, above.
+Returns the number of screen cells that are in use (``the line
+length''). Unlike the urxvt core, this returns $term->ncol if the
+line is joined with the following one.
Returns true if the row is part of a multiple-row logical ``line'' (i.e. +joined with the following row), which means all characters are in use +and it is continued on the next row (and possibly a continuation of the +previous row(s)).
+Create and return a new urxvt::line object that stores information
+about the logical line that row $row_number is part of. It supports the
+following methods:
Returns or replaces the full text of the line, similar to ROW_t
Returns or replaces the full rendition array of the line, similar to ROW_r
Returns the length of the line in cells, similar to ROW_l.
Return the row number of the first/last row of the line, respectively.
+Returns the character offset of the given row|col pair within the logical +line. Works for rows outside the line, too, and returns corresponding +offsets outside the string.
+Translates a string offset into terminal coordinates again.
+Converts a perl string into the special encoding used by rxvt-unicode,
+where one character corresponds to one screen cell. See
+$term->ROW_t for details.
Converts rxvt-unicodes text reprsentation into a perl string. See
+$term->ROW_t for details.
Register/unregister a synchronous button grab. See the XGrabButton +manpage.
+Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
+synchronous ($sync is true). Also remembers the grab timestampe.
Calls XAllowEvents with AsyncBoth for the most recent grab.
+Calls XAllowEvents with SyncBoth for the most recent grab.
+Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for the most +recent grab.
+Calls XUngrab for the most recent grab. Is called automatically on +evaluation errors, as it is better to lose the grab in the error case as +the session.
+Various X or X-related functions. The $term object only serves as
+the source of the display, otherwise those functions map more-or-less
+directory onto the X functions of the same name.
+
+urxvt::popup ClassAdds a non-clickable title to the popup.
+Creates a separator, optionally using the character given as $sepchr.
Adds a clickable button to the popup. $cb is called whenever it is
+selected.
Adds a toggle/checkbox item to the popup. The callback gets called +whenever it gets toggled, with a boolean indicating its new value as its +first argument.
+Displays the popup (which is initially hidden).
+
urxvt::timer ClassThis class implements timer watchers/events. Time is represented as a fractional number of seconds since the epoch. Example:
- # create a digital clock display in upper right corner
+ $term->{overlay} = $term->overlay (-1, 0, 8, 1, urxvt::OVERLAY_RSTYLE, 0);
$term->{timer} = urxvt::timer
->new
- ->start (urxvt::NOW)
+ ->interval (1)
->cb (sub {
- my ($timer) = @_;
- my $time = $timer->at;
- $timer->start ($time + 1);
- $self->scr_overlay (-1, 0,
- POSIX::strftime "%H:%M:%S", localtime $time);
+ $term->{overlay}->set (0, 0,
+ sprintf "%2d:%02d:%02d", (localtime urxvt::NOW)[2,1,0]);
});
Create a new timer object in started state. It is scheduled to fire +immediately.
Set the callback to be called when the timer triggers.
Return the time this watcher will fire next.
Set the time the event is generated to $tstamp.
Normally (and when $interval is 0), the timer will automatically
+stop after it has fired once. If $interval is non-zero, then the timer
+is automatically rescheduled at the given intervals.
Start the timer.
+Set the event trigger time to $tstamp and start the timer.
$tstamp and start the timer.
+Like start, but sets the expiry timer to c<urxvt::NOW + $delay>.
Stop the timer.
urxvt::iow ClassCreate a new io watcher object in stopped state.
+Set the callback to be called when io events are triggered. $reventmask
+is a bitset as described in the events method.
Set the filedescriptor (not handle) to watch.
+Set the event mask to watch. The only allowed values are
+urxvt::EVENT_READ and urxvt::EVENT_WRITE, which might be ORed
+together, or urxvt::EVENT_NONE.
Start watching for requested events on the given handle.
+Stop watching for events on the given filehandle.
++
+urxvt::iw ClassThis class implements idle watchers, that get called automatically when +the process is idle. They should return as fast as possible, after doing +some useful work.
+Create a new idle watcher object in stopped state.
$reventmask
-is a bitset as described in the events method.
+Set the callback to be called when the watcher triggers.
Start the watcher.
1) enables watching for read
-data, Bit #1 (value 2) enables watching for write data.
+Stop the watcher.
+
+urxvt::pw ClassThis class implements process watchers. They create an event whenever a +process exits, after which they stop automatically.
+
+ my $pid = fork;
+ ...
+ $term->{pw} = urxvt::pw
+ ->new
+ ->start ($pid)
+ ->cb (sub {
+ my ($pw, $exit_status) = @_;
+ ...
+ });
+Create a new process watcher in stopped state.
+Set the callback to be called when the timer triggers.
+Tells the wqtcher to start watching for process $pid.
Stop the watcher.
This variable controls the verbosity level of the perl extension. Higher numbers indicate more verbose output.
